The estimated 10-year risk of first-onset cardiovascular disease in Swedish-born and non-Swedish-born primary healthcare patients

BackgroundSCORE2 has been introduced as an updated risk assessment tool for calculating the 10-year risk of first-onset cardiovascular disease (CVD). However, it does not account for ethnicity or socioeconomic status, known to affect CVD risk. This study investigated and compared SCORE2 estimates in Swedish-born and non-Swedish-born primary healthcare patients. The second aim was to examine if several risk factors could explain differences in CVD risk between the groups.MethodsThis was an observational, cross-sectional study. Data were obtained from the 4D Diabetes Project study, providing a total of 444 participants aged between 40 and 69 years. All participants had complete risk variable data necessary for the SCORE2 tool and no history of previous CVD. Descriptive analysis was conducted to compare distributions of risk factors between Swedes and immigrants and odds ratios of risk factors amongst these two groups in correlation to elevated CVD risk were calculated using logistic regression.ResultsSwedish-born patients showed a significantly higher risk of elevated CVD risk estimates (≥ 2.5% CVD risk increase for individuals < 50 years, respectively, ≥ 5% for individuals aged 51–69) than the non-Swedish-born population, even after adjustment for educational level (OR = 1.61, 95% CI 1.08–2.39). Weekly alcohol consumption implicated a risk of being classified as high risk of CVD risk, regardless of country of birth (OR = 1.93 CI 1.25-3.00). However, Swedes accounted for most of the alcohol consumption (62.6% vs. 19.6%). No other explanatory variable showed significance in association with elevated CVD risk.ConclusionsSwedish-born patients were found to be at higher risk of an increased 10-year CVD risk. The association of alcohol consumption with elevated CVD risk needs to be further studied in longitudinal studies in representative populations, notably among Sweden’s diverse ethnic groups.

Associations of Alcohol Consumption With Left Atrial Morphology and Function in a Population at High Cardiovascular Risk.

Excessive alcohol consumption has been associated with increased risk of atrial fibrillation, although the underlying mechanisms remain unclear. An enlarged left atrium and impaired left atrial function may lead to atrial fibrillation. The association of alcohol consumption with structural and functional left atrial measures, however, has received limited attention. We studied 503 participants from the PREDIMED-Plus (Prevención con Dieta Mediterránea) trial, a randomized trial testing intensive weight loss intervention with an energy-reduced Mediterranean diet and physical activity promotion in preventing cardiovascular disease in adults with metabolic syndrome. Participants underwent transthoracic echocardiography at baseline, year 3, and year 5 of the study. Outcomes of interest included volume index and reservoir, conduit, and contractile strains of the left atrium. Alcohol consumption was calculated through food frequency questionnaires and presented as drinks consumed per day. Multiple linear regression and mixed models estimated the association of alcohol consumption with left atrial measurements at baseline and through follow-up. Cross-sectionally, higher alcohol consumption (per 1 drink/day increases) was associated with larger left atrial volume (0.65 mL/m2 [95% CI, 0.18-1.11]) and lower left atrial reservoir and contractile strain (-0.44% [95% CI, -0.87 to -0.01]; and -0.44% [95% CI, -0.75 to -0.14]). Baseline alcohol consumption was not associated with changes in left atrial measurements, but increases in alcohol consumption (per 1 drink/day increase) during follow-up were associated with left atrial enlargement (0.71 mL/m2 [95% CI, 0.17-1.26]). In a population at high cardiovascular risk, increased alcohol consumption was associated with left atrial enlargement and worsening atrial function.

Association of Alcohol Consumption with Cognition and Functionality in Older Adults Aged 75+ Years: The Pietà Study.

The relationship between alcohol consumption and cognition is still controversial. This is a cross-sectional population-based study conducted in Caeté (MG), Brazil, where 602 individuals aged 75+ years, 63.6% female, and with a mean education of 2.68years, were submitted to thorough clinical assessments and categorized according to the number of alcoholic beverages consumed weekly. The prevalence rates of previous and current alcohol consumption were 34.6% and 12.3%, respectively. No association emerged between cognitive diagnoses and current/previous alcohol consumption categories. Considering current alcohol intake as a dichotomous variable, the absence of alcohol consumption was associated with dementia (OR=2.34; 95%CI: 1.39-3.90) and worse functionality (p=0.001). Previous consumption of cachaça (sugar cane liquor) increased the risk of dementia by 2.52 (95%CI: 1.25-5.04). The association between the consumption of cachaça and dementia diagnosis has not been described before.

Alcohol Consumption, High-Density Lipoprotein Particles and Subspecies, and Risk of Cardiovascular Disease: Findings from the PREVEND Prospective Study.

The associations of HDL particle (HDL-P) and subspecies concentrations with alcohol consumption are unclear. We aimed to evaluate the interplay between alcohol consumption, HDL parameters and cardiovascular disease (CVD) risk. In the PREVEND study of 5151 participants (mean age, 53 years; 47.5% males), self-reported alcohol consumption and HDL-P and subspecies (small, medium, and large) by nuclear magnetic resonance spectroscopy were assessed. Hazard ratios (HRs) with 95% CIs for first CVD events were estimated. In multivariable linear regression analyses, increasing alcohol consumption increased HDL-C, HDL-P, large and medium HDL, HDL size, and HDL subspecies (H3P, H4P, H6 and H7) in a dose-dependent manner. During a median follow-up of 8.3 years, 323 first CVD events were recorded. Compared with abstainers, the multivariable adjusted HRs (95% CIs) of CVD for occasional to light, moderate, and heavy alcohol consumers were 0.72 (0.55-0.94), 0.74 (0.54-1.02), and 0.65 (0.38-1.09), respectively. These associations remained consistent on additional adjustment for each HDL parameter. For CVD, only HDL-C was associated with a statistically significant decreased risk of CVD in a fully adjusted analysis (HR 0.84, 95% CI 0.72-0.97 per 1 SD increment). For coronary heart disease, HDL-C, HDL-P, medium HDL, HDL size, and H4P showed inverse associations, whereas HDL-C and HDL size modestly increased stroke risk. Except for H6P, alcohol consumption did not modify the associations between HDL parameters and CVD risk. The addition of HDL-C, HDL size, or H4P to a CVD risk prediction model containing established risk factors improved risk discrimination. Increasing alcohol consumption is associated with increased HDL-C, HDL-P, large and medium HDL, HDL size, and some HDL subspecies. Associations of alcohol consumption with CVD are largely independent of HDL parameters. The associations of HDL parameters with incident CVD are generally not attenuated or modified by alcohol consumption.

Interaction of genetic variation at ADH1B and MLXIPL with alcohol consumption for elevated serum urate level and gout among people of European ethnicity

BackgroundAlcohol consumption is a risk factor for hyperuricaemia and gout. Multiple single-nucleotide polymorphisms (SNPs) have been identified as associated with both alcohol consumption and serum urate or gout in separate genome-wide association studies (GWAS). This study aimed to identify and characterise interactions between these shared signals of genetic association and alcohol consumption for serum urate level, hyperuricaemia, and gout.MethodsThis research was conducted using the UK Biobank resource. The association of alcohol consumption with serum urate and gout was tested among 458,405 European participants. Candidate SNPs were identified by comparing serum urate, gout, and alcohol consumption GWAS for shared signals of association. Multivariable-adjusted linear and logistic regression analyses were conducted with the inclusion of interaction terms to identify SNP-alcohol consumption interactions for association with serum urate level, hyperuricaemia, and gout. The nature of these interactions was characterised using genotype-stratified association analyses.ResultsAlcohol consumption was associated with elevated serum urate and gout. For serum urate level, non-additive interactions were identified between alcohol consumption and rs1229984 at the ADH1B locus (P = 3.0 × 10−44) and rs6460047 at the MLXIPL locus (P = 1.4 × 10−4). ADH1B also demonstrated interaction with alcohol consumption for hyperuricaemia (P = 7.9 × 10−13) and gout (P = 8.2 × 10−9). Beer intake had the most significant interaction with ADH1B for association with serum urate and gout among men, while wine intake had the most significant interaction among women. In the genotype-stratified association analyses, ADH1B and MLXIPL were associated with serum urate level and ADH1B was associated with hyperuricaemia and gout among consumers of alcohol but not non-consumers.ConclusionsIn this large study of European participants, novel interactions with alcohol consumption were identified at ADH1B and MLXIPL for association with serum urate level and at ADH1B for association with hyperuricaemia and gout. The association of ADH1B with serum urate and gout may occur through the modulation of alcohol metabolism rate among consumers of alcohol.

Association of Alcohol Consumption with Impaired Beta-Cell Function Independent of Body Mass Index Among Indian Men

Heavy alcohol consumption is linked to the development of type 2 diabetes. Alcohol's effects on the function of cells are not completely known at this time. This investigation looked into the relationships that exist between all of these different characteristics. All of the males who participated in this study were of Indian descent, and their ages ranged anywhere from 25 to 80 years old. Participants were categorized as abstainers, teetotalers, light drinkers (drinking between 0.1 and 20 grams of alcohol per day), moderate drinkers (consuming between 21.0 and 40 grams of alcohol per day), or heavy drinkers (consuming more than 41 grams of alcohol per day). Light drinkers consumed between 0.1 and 20 grams of alcohol per day. Moderate drinkers consumed between 21.0 and 40 kilos of alcohol per day. Heavy drinkers used more than 41 grams of alcohol per day. After that, the participants were separated into two groups: those with a body mass index (BMI) of less than 25 kilograms per square meter and those with a BMI of 25 kilograms per square meter or more. A number of parameters, such as age, smoking status, body mass index (BMI), waist circumference, blood pressure, lipids, and serum uric acid levels, were taken into consideration. In comparison to individuals who refrained from alcohol use, those who drank alcohol had a lower HOMA- score, and this was the case independent of their body mass index. In the group with a BMI of less than 25 \(kg/m^{2}\), both past and current alcohol use were substantially connected with HOMA-IR. However, this association was not seen in the group with a BMI of more than 25 \(kg/m^{2}\). According to the results of multiple research, drinking alcohol is associated with -cell dysfunction in boys of Indian heritage, independent of the BMI of the participants in the studies.

Association of Alcohol Consumption With CD4 Recovery After Antiretroviral Therapy Initiation in St. Petersburg, Russia.

Delayed CD4 recovery after initiating antiretroviral therapy (ART) is a novel potential mechanism by which alcohol consumption leads to increased morbidity and mortality in people with HIV. We hypothesized that alcohol consumption at ART initiation is associated with slower CD4 recovery. We retrospectively analyzed 2 pooled longitudinal alcohol/HIV cohorts (2014-2019) in St. Petersburg, Russia. Eligible participants initiated the first ART during parent studies; had alcohol consumption assessed by the blood biomarker, phosphatidylethanol (PEth), at the last research visit before ART initiation; and had ≥1 CD4 count measurement before and after initiating ART. Participants were stratified by low, moderate, and high PEth (<8, 8-80, and >80 ng/mL, respectively). We used random-effects piecewise linear regression models to estimate CD4 recovery, defined as CD4 count change per 30 days after ART initiation, by the alcohol group. Of 60 eligible participants, median age was 34 years and 28% were female. The median pre-ART PEth in the low, moderate, and high PEth groups were <8, 23, and 232 ng/mL, respectively. After starting ART, the CD4 count increased by 13.60 cells/mm3/mo (95% CI: 0.33 to 26.87) with low PEth, 0.93 cells/mm3/mo (95% CI: -6.18 to 8.04) with moderate PEth, and 2.33 cells/mm3/mo (95% CI: -3.44 to 8.09) with high PEth. Among Russians with HIV, we observed faster CD4 recovery after ART initiation in those with low alcohol consumption compared with those with moderate and high alcohol consumption, as assessed by PEth. This analysis provides further evidence for the possible value of alcohol reduction interventions for people with HIV who are initiating ART.

Associations of Alcohol Consumption and Smoking Behaviors with Depressed Mood According to Gender in Korean Young Adults.

Recent studies have reported that chronic mental health problems often emerge in young adulthood. This study elucidated the independent effects of smoking and drinking on depressed mood in young adults by sex. We used Data from the Korea National Health and Nutrition Examination Surveys conducted in 2014, 2016, and 2018. A total of 3,391 participants aged 19-35 years, without serious chronic diseases, were recruited for this study. Depression was evaluated using the Patient Health Questionnaire (PHQ-9). Smoking behavior, current smoking, and number of days smoked were significantly associated with higher PHQ-9 scores in both men and women (all P<0.05). However, past and ever smoking were positively associated with PHQ-9 scores only in women (all P<0.001). Regarding alcohol consumption, the age at which drinking first began was negatively associated with PHQ-9 scores in both men and women (all P<0.001), but the amount of alcohol consumed at 1 time was positively associated with PHQ-9 scores only in women (P=0.013). Men who drank 2-4 times a month and women who had not drunk during the past year had the lowest PHQ-9 scores. Smoking and alcohol consumption were independently associated with depressed mood in young Korean adults, which was more pronounced in women, and exhibited sex-specific characteristics.

Drinking alcohol in moderation is associated with lower rate of all-cause mortality in individuals with higher rather than lower educational level: findings from the MORGAM project.

The association between socioeconomic status (SES) and alcohol-related diseases has been widely explored. Less is known, however, on whether the association of moderate drinking with all-cause mortality is modified by educational level (EL). Using harmonized data from 16 cohorts in the MORGAM Project (N = 142,066) the association of pattern of alcohol intake with hazard of all-cause mortality across EL (lower = primary-school; middle = secondary-school; higher = university/college degree) was assessed using multivariable Cox-regression and spline curves. A total of 16,695 deaths occurred in 11.8years (median). In comparison with life-long abstainers, participants drinking 0.1-10g/d of ethanol had 13% (HR = 0.87; 95%CI: 0.74-1.02), 11% (HR = 0.89; 0.84-0.95) and 5% (HR = 0.95; 0.89-1.02) lower rate of death in higher, middle and lower EL, respectively. Conversely, drinkers > 20g/d had 1% (HR = 1.01; 0.82-1.25), 10% (HR = 1.10; 1.02-1.19) and 17% (HR = 1.17; 1.09-1.26) higher rate of death. The association of alcohol consumption with all-cause mortality was nonlinear, with a different J-shape by EL levels. It was consistent across both sexes and in various approaches of measuring alcohol consumption, including combining quantity and frequency and it was more evident when the beverage of preference was wine. We observed that drinking in moderation (≤ 10g/d) is associated with lower mortality rate more evidently in individuals with higher EL than in people with lower EL, while heavy drinking is associated with higher mortality rate more evidently in individuals with lower EL than in people with higher EL, suggesting that advice on reducing alcohol intake should especially target individuals of low EL.

Association of Alcohol Consumption with Cognition in Older Population: The A4 Study.

Alcohol use disorders have been categorized as a 'strongly modifiable' risk factor for dementia. To investigate the cross-sectional association between alcohol consumption and cognition in older adults and if it is different across sexes or depends on amyloid-β (Aβ) accumulation in the brain. Cognitively unimpaired older adults (N = 4387) with objective and subjective cognitive assessments and amyloid positron emission tomography (PET) imaging were classified into four categories based on their average daily alcohol use. Multivariable linear regression was then used to test the main effects and interactions with sex and Aβ levels. Individuals who reported no alcohol consumption had lower scores on the Preclinical Alzheimer Cognitive Composite (PACC) compared to those consuming one or two drinks/day. In sex-stratified analysis, the association between alcohol consumption and cognition was more prominent in females. Female participants who consumed two drinks/day had better performance on PACC and Cognitive Function Index (CFI) than those who reported no alcohol consumption. In an Aβ-stratified sample, the association between alcohol consumption and cognition was present only in the Aβ- subgroup. The interaction between Aβ status and alcohol consumption on cognition was not significant. Low or moderate consumption of alcohol was associated with better objective cognitive performance and better subjective report of daily functioning in cognitively unimpaired individuals. The association was present only in Aβ- individuals, suggesting that the pathophysiologic mechanism underlying the effect of alcohol on cognition is independent of Aβ pathology. Further investigation is required with larger samples consuming three or more drinks/day.

Association of alcohol consumption with all-cause mortality, new-onset stroke, and coronary heart disease in patients with abnormal glucose metabolism-Findings from a 10-year follow-up of the REACTION study.

Type 2 diabetes mellitus (T2DM) and diabetic complications threaten human health seriously. Healthy lifestyles can lower the risk of cardiovascular disease (CVD) and long-term complications. However, the relationship between alcohol consumption and CVD mortality is still controversial, and there is a lack of evidence from large-scale longitudinal studies in the Chinese population. Based on the REACTION study (Risk Evaluation of Cancers in Chinese Diabetic Individuals: A Longitudinal Study), this paper explores the association between alcohol consumption and all-cause mortality, stroke, and coronary heart disease (CHD) in patients with abnormal glucose metabolism during a 10-year follow-up period to provide evidence for lifestyle counselling for these patients. First, baseline data were collected from the REACTION study cohort in Changchun, Jilin Province, China, in 2011-2012. A questionnaire survey was performed among patients with abnormal glucose metabolism aged over 40 years. The frequency of their alcohol intake, the type of alcohol, and the amount of alcohol consumed daily were surveyed. Physical and biochemical examinations were also performed. Then, through the Primary Public Health Service System of Jilin Province, we collected outcomes during the 10-year follow-up up to October 1, 2021, including all-cause mortality, stroke, and CHD. Next, we conducted logistic regression to analyze the relationship between baseline alcohol consumption and 10-year outcomes, and risk ratio (RR) and 95% CI were calculated by adjusting for different clinical indicators. A p value < 0.05 was considered statistically significant. A total of 4855 patients with T2DM and prediabetes (35.2% men and 64.8% women) were included in the baseline analysis. Outcomes of 3521 patients during the 10-year follow-up were obtained, including 227 deaths, 296 new-onset strokes and 445 new-onset CHD. Occasional drinking (less than once a week) was associated with a reduced 10-year all-cause mortality, with an RR of 0.511 (95% CI [0.266, 0.982]) after adjustment for age, gender, medical history, and lifestyles and an RR of 0.50 (95% CI [0.252, 0.993]) in a fully adjusted model including additional biochemical indicators. In addition, heavy alcohol consumption (≥30 g/day for men and ≥15 g/day for women) was significantly associated with an increased incidence of stroke, with an RR of 2.503 (95% CI [1.138, 5.506]) after the adjustment for age, gender, medical history, lifestyles, and biochemical indicators. No significant association was found between alcohol consumption and new-onset CHD. For patients with abnormal glucose metabolism, occasional drinking (less than once a week) reduces the risk of all-cause mortality, while heavy alcohol consumption (≥30 g/day for men and ≥15 g/day for women) significantly increases the risk of new-onset stroke. They should avoid heavy alcohol intake, but light alcohol consumption or occasional drinking is acceptable. Additionally, it is crucial to control blood glucose and blood pressure and keep performing physical activities.

Associations of alcohol consumption with breast tissue composition

BackgroundWe investigated the associations of alcohol with percentage of epithelium, stroma, fibroglandular tissue (epithelium + stroma), and fat in benign breast biopsy samples.MethodsWe included 857 cancer-free women with biopsy-confirmed benign breast disease within the Nurses’ Health Study (NHS) and NHSII cohorts. Percentage of each tissue was measured on whole slide images using a deep-learning algorithm and then log-transformed. Alcohol consumption (recent and cumulative average) was assessed with semi-quantitative food frequency questionnaires. Regression estimates were adjusted for known breast cancer risk factors. All tests were 2-sided.ResultsAlcohol was inversely associated with % of stroma and fibroglandular tissue (recent ≥ 22 g/day vs. none: stroma: β = − 0.08, 95% Confidence Interval [CI] − 0.13; − 0.03; fibroglandular: β = − 0.08, 95% CI − 0.13; − 0.04; cumulative ≥ 22 g/day vs. none: stroma: β = − 0.08, 95% CI − 0.13; − 0.02; fibroglandular: β = − 0.09, 95% CI − 0.14; − 0.04) and positively associated with fat % (recent ≥ 22 g/day vs. none: β = 0.30, 95% CI 0.03; 0.57; cumulative ≥ 22 g/day vs. none: β = 0.32, 95% CI 0.04; 0.61). In stratified analysis, alcohol consumption was not associated with tissue measures in premenopausal women. In postmenopausal women, cumulative alcohol use was inversely associated with % of stroma and fibroglandular tissue and positively associated with fat % (≥ 22 g/day vs. none: stroma: β = − 0.16, 95% CI − 0.28; − 0.07; fibroglandular: β = − 0.18, 95% CI − 0.28; − 0.07; fat: β = 0.61, 95% CI 0.01; 1.22), with similar results for recent alcohol use.ConclusionOur findings suggest that alcohol consumption is associated with smaller % of stroma and fibroglandular tissue and a greater % of fat in postmenopausal women. Future studies are warranted to confirm our findings and to elucidate the underlying biological mechanisms.

Association of Alcohol Consumption With Liver Cancer and All-Cause Mortality in Chronic Hepatitis B Patients Without Cirrhosis

Association of Alcohol Consumption With Liver Cancer and All-Cause Mortality in Chronic Hepatitis B Patients Without Cirrhosis

Abstract P617: Light to Moderate Alcohol Consumption is Not Associated With Breast Cancer Incidence in Italian Adult Women: Results From the Moli-Sani Study

Introduction: Epidemiologic studies suggest that heavy alcohol drinking is associated with unhealthy profile, whereas its light to moderate intake is associated with reduced hazard of total mortality as compared with lifetime abstention, a result largely driven by a reduction in cardiovascular mortality. Up to date, there is no agreement on a possible safe threshold for alcohol consumption in relation with cancer risk, especially breast cancer (BC) in women. Hypothesis: We assessed the hypothesis that the association of alcohol consumption with development of BC is mostly dependent on the average daily volume consumed. Methods: A prospective investigation was conducted on 11,394 women (age ≥35y) from the Moli-sani study (apparently free from any cancer at baseline; 2005-2010). The alcohol volume consumed in the year before enrolment was classified as: lifetime or former or occasional drinkers and current drinkers who drank 1-12, 12.1-24, and &gt; 24 g/d. Incident cases of BC were validated through medical and histological records. Multivariable hazard ratio (HR) and 95% confidence interval (CI) for BC were estimated using Cox proportional hazard models and multiple imputation for missing data on covariates. Results: During a median follow-up of 13.2 years, 296 BC events occurred. In comparison with lifetime abstention, intake of alcohol up to 12 g/d was not associated with BC, while consumption &gt;12 g/d had higher hazard of BC (Table). These findings remained consistent after the exclusion of BC events occurred during the first 12 months of follow-up or stratifying by BC subtypes (Table). Conclusions: Drinking up to one unit of alcohol (12 g) per day was not associated with either a protection or an increased BC risk in women. In contrast, drinking more than 12 g/d of alcohol had hazardous impact on BC incidence. These findings contribute to the current literature debate, suggesting that there is indeed an alcohol threshold below which alcohol drinking would not affect breast cancer risk.

Association of alcohol consumption and fatigue in SLE: A cross-sectional study from Lupus Registry of Nationwide Institution (LUNA) cohort.

Fatigue is one of the most common complaints and is a potentially modifiable issue in systemic lupus erythematosus (SLE). Studies suggest that alcohol consumption has a protective effect against the development of SLE; however, an association between alcohol consumption and fatigue in patients with SLE has not been studied. Here, we assessed whether alcohol consumption was associated with fatigue using lupus patient-reported outcomes (LupusPRO). This cross-sectional study, conducted between 2018 and 2019, included 534 patients (median age, 45years; 87.3% female) from 10 institutions in Japan. The main exposure was alcohol consumption, which was defined as the frequency of drinking [<1day/month (none group), ≤1day/week (moderate group), and ≥2days/week (frequent group)]. The outcome measure was the Pain Vitality domain score in LupusPRO. Multiple regression analysis was performed as the primary analysis after adjusting for confounding factors, such as age, sex, and damage. Subsequently, the same analysis was performed as a sensitivity analysis after multiple imputations (MIs) for missing data (n = 580). In total, 326 (61.0%) patients were categorized into the none group, 121 (22.7%) into the moderate group, and 87 (16.3%) into the frequent group. The frequent group was independently associated with less fatigue compared with none group [β = 5.98 (95% CI 0.19-11.76), p = 0.04], and the results did not substantially deviate after MI. Frequent drinking was associated with less fatigue, which highlights the need for further longitudinal studies focusing on drinking habits in patients with SLE.

Association between Alcohol Intake and Prostate Cancer Mortality and Survival.

We conducted a systematic review and meta-analysis to investigate the role of alcohol consumption with the prognosis of prostate cancer (PCa). Published reports were gathered on 15 October 2022, from PUBMED/MEDLINE and EMBASE. We found 19 independent eligible studies on the association between consumption of alcoholic beverages and the risk of fatal PCa (n = 5), PCa mortality (n = 5) in healthy subjects, and PCa patients' survival (n = 7) or surrogates thereof (n = 2). We used random effects meta-analysis to obtain a summary risk estimate (SRE) and 95% confidence intervals (95%CI) for incidence of fatal PCa and PCa mortality. The meta-analysis revealed no association between alcohol consumption and fatal prostate cancer incidence risk in healthy subjects with an indication for publication bias, but omitting the study that mainly increased the between-study heterogeneity, the SRE becomes significant (SRE 1.33, 95%CI 1.12-1.58), and the heterogeneity disappeared (I2 = 0%) with no indication of publication bias. No association of alcohol consumption was found with mortality risk in PCa patients (SRE 0.97, 95%CI 0.92-1.03) and PCa mortality risk in healthy subjects (SRE 1.03, 95%CI 0.82-1.30). In conclusion, this study suggests that there is some evidence of an association between high alcohol consumption and an increased risk of incidence of fatal prostate cancer in healthy subjects. Given the inconsistencies this result warrants further confirmation.

Association of alcohol consumption with telomere length in humans: a systematic review

Telomeres are complex nucleoprotein structures with specific proteins of noncoding terminal regions of linear chromosomes of eukaryotic cells. Telomere DNA consists of a large number of short sequence repeats (TTAGGG in vertebrates). Telomeres protect chromosomes from their fusion and degradation, limit the proliferative potential of the cell, participate in the segregation of chromosomes during cell division, etc. Reduction of telomeres length is an important factor with significant impact on cell viability and function, aging, and leads to the development of various diseases including cancer.&#x0D; Alcohol abuse has a significant impact on a person's health. Ethanol consumption by a human potentially affects the length of chromosome telomeres on the cellular level.&#x0D; Current review represents systematic analysis of studies on the effect of alcohol consumption on telomere length in humans. PubMed and eLIBRARY.RU databases were explored for the combinations of the terms ("Ethanol" OR "Alcohol") AND "Telomer" with a limitation on the publication date until 01 January 2011. The search resulted in 269 studies. In accordance with the preset criteria, total 238 studies were excluded from the analysis, and 3 publications were excluded due to unavailability of full text. A total of 28 epidemiological and clinical studies were included for this study review.&#x0D; The association of alcohol consumption with shortening of telomeres was reported in 16 of the studies conducted with various populations and cohorts including individuals with alcohol abuse, alcohol dependence, and some genetic variants of alcohol metabolism enzymes. 12 studies reported alcohol consumption was not associated with change in telomere length.&#x0D; The analysis of reviewed studies allows to conclude that they are ambiguous and that there is further urgency to study the effect of alcohol on telomere length by engaging modern methods for its determination.

Association of alcohol consumption with the prevalence and various stages of chronic kidney disease.

Considering that the effect of alcohol consumption trend on the prevalence of kidney damage and its progression has not been determined yet, the study aimed at investigating the association between alcohol consumption and the risk of chronic kidney disease (CKD) prevalence and progression at various stages of the disease. This cross-sectional study was performed on 3374 participants that referred to health-care centers in Isfahan from 2017 to 2019. Participants' basic and clinical characteristics (such as sex, age, education level, marital status, body mass index, blood pressure, alcohol consumption, comorbidities, and laboratory parameters) were evaluated and recorded. The alcohol consumption trend was classified as never, occasional (<6 drinks/week), and frequent (≥6 drinks/week) based on the amount of alcohol consumption over the last 3 months. Moreover, CKD stages were recorded based on the Kidney Disease: Improving Global Outcomes guideline, as well. In the present study, the occasional and frequent drinking of alcohol did not have a significant effect on the odds of CKD prevalence (odds ratio [OR]: 1.32 and 0.54; P > 0.05) and the odds of stage 2 CKD prevalence as compared to stage 1 CKD prevalence (OR: 0.93 and 0.47; P > 0.05). However, adjusting the confounding factors revealed that occasional drinking as compared to nondrinking increased the odds of stage 3 and 4 CKD prevalence as compared to stage 1 CKD prevalence by 3.35 folds, respectively (P < 0.05). According to the results of this study, occasional drinking as compared to nondrinking significantly increased the odds of stage 3 and 4 CKD prevalence as compared to stage 1 CKD prevalence.

Alcohol consumption: context and association with mortality in Switzerland

PurposeNon-communicable diseases generate the largest number of avoidable deaths often caused by risk factors such as alcohol, smoking, and unhealthy diets. Our study investigates the association between amount and context of alcohol consumption and mortality from major non-communicable diseases in Switzerland.MethodsGeneralized linear regression models were fitted on data of the cross-sectional population-based National Nutrition Survey menuCH (2014–2015, n = 2057). Mortality rates based on the Swiss mortality data (2015–2018) were modeled by the alcohol consumption group considering the amount and context (i.e., during or outside mealtime) of alcohol consumption and potential confounders. The models were checked for spatial autocorrelation using Moran’s I statistic. Integrated nested Laplace approximation (INLA) models were fitted when evidence for missing spatial information was found.ResultsHigher mortality rates were detected among drinkers compared to non-drinkers for all-cancer (rate ratio (RR) ranging from 1.01 to 1.07) and upper aero-digestive tract cancer (RR ranging from 1.15 to 1.20) mortality. Global Moran’s I statistic revealed spatial autocorrelation at the Swiss district level for all-cancer mortality. An INLA model led to the identification of three districts with a significant decrease and four districts with a significant increase in all-cancer mortality.ConclusionSignificant associations of alcohol consumption with all-cancer and upper aero-digestive tract cancer mortality were detected. Our study results indicate the need for further studies to improve the next alcohol-prevention scheme and to lower the number of avoidable deaths in Switzerland.

Insulin resistance phenotype is associated with vascular risk phenotype at the end of the second decade of life: a population-based study

We hypothesize that early events of diabetes and cardiovascular disease continuums would be ongoing and associated in adolescents. We investigated the association between the Insulin Resistance Phenotype and the Vascular Risk Phenotype at the end of the second decade of life and indirect pathways from social vulnerability, alcohol consumption, and body fat mass. It is a population-based study in the RPS cohort of 18–19 years (n = 2,515), São Luís, Brazil. The theoretical model analyzed the association between Insulin Resistance Phenotype and Vascular Risk Phenotype by sex, using structural equation modeling (SEM). The Insulin Resistance Phenotype was a latent variable deduced from the correlations of Triglyceride to HDL ratio, Triglyceride Glycemic index, and VLDL; the Vascular Risk Phenotype was deduced from Systolic Blood Pressure, Diastolic Blood Pressure, and Pulse Wave Velocity. The Insulin Resistance Phenotype was directly associated with the Vascular Risk Phenotype in males (standardized coefficient SC = 0.183; p < 0.001) and females (SC = 0.152; p < 0.001). The Insulin Resistance Phenotype was an indirect pathway in the association of alcohol consumption and higher values of fat mass index with the Vascular Risk Phenotype. VLDL presented the highest factor loading, appearing as a marker of insulin resistance linked to cardiovascular risk in young people. Lower values of socioeconomic status, harmful use of alcohol, and high body fat values were also associated with higher values of the two phenotypes. The association of the Insulin Resistance Phenotype with the Vascular Risk Phenotype suggests common pathophysiological mechanisms present in early events in the continuums of diabetes and cardiovascular disease in adolescence.
