Moderate Alcohol Consumption Research Articles

Alcohol consumption-none is better than alittle.

Alcohol is socially accepted and widely consumed as arecreational beverage. Furthermore, it is used as adisinfectant for medicinal purposes and as acultural asset it is also part of religious rituals. However, it is also an intoxicant and an addictive substance. The deleterious side of alcohol is reflected in the fact that around 3million people worldwide die every year as adirect or indirect result of alcohol consumption. For several decades, epidemiological studies suggested that drinking alcohol in moderate quantities was beneficial. This was referred to as the "French paradox," which described differences in mortality between France and Finland mainly, but also other countries, that were found in epidemiological studies. The difference in the levels of alcohol consumption was found to explain the differences in mortality in view of the otherwise similar risk factors. When alcoholic drinks per day were plotted against all-cause mortality this led to aJ-shaped curve. This finding represented awindow of benefit for moderate alcohol consumption. However, the recent publication by Zhao etal. in 2023 revisited the relationship between the quantity of alcohol consumed and mortality risk and led to aparadigm change, which has influenced not only the recommendations of Canada's Guidance on Alcohol and Health but also the recommendations and guidelines of major health organizations: "No alcohol is better than alittle." The J‑shaped curve as an explanation of the French paradox became alinear relationship between the amount of alcohol consumption and the increasing mortality from tumors and cardiovascular diseases. The renewed review of several control groups in previous epidemiological studies revealed arecruitment error due to the inclusion of abstinent ex-drinkers. Taking this bias into account, the alcohol-friendly view of small amounts of alcohol being cardioprotective had to be revised. The combined misuse of alcohol and other risk factors for carcinogenesis and heart diseases still needs further attention. The misuse of both alcohol and cocaine led to the conclusion that when the two risky substances are consumed together, it is even more detrimental than the mere sum of the two.

Employee well-being in the digital age: Assessing the impacts of a smartphone application in the workplace

Recently, providing smartphone-based health-improving applications to employees has emerged as a promising strategy for sustaining their well-being. This study estimates the impact of the routine use of an application, introduced in 2020 by a Japanese manufacturing company, on various health-related behaviours and outcomes among employees by exploiting a distinctive large-scale longitudinal dataset and personnel records. The analysis addresses potential selection biases arising from the non-random nature of application usage by employing the instrumental variable approach. Regular application use generates significant positive impacts on health-related habits, including moderate alcohol consumption, regular breakfast intake and refraining from eating two hours before bedtime. Furthermore, regarding physical and psychological stress, noteworthy reductions in physical burden and less frequent experiences of annoyance are observed. Employees also report a lower frequency of dizziness, headaches and palpitations, albeit an increase in the frequency of strained eyes is noted. Additionally, application use is associated with lower systolic and diastolic blood pressure, as well as decreased levels of triglycerides and gamma-GTP.

Exploring the effects of reduced alcohol consumption on major adverse cardiovascular and cerebrovascular events in chronic heavy drinkers: a nationwide population-based cohort study

Abstract Background/Introduction Chronic heavy alcohol consumption is a well-established risk factor for cardiovascular disease (CVD), and the potential cardiovascular benefits of mild to moderate alcohol consumption need validation, particularly in the context of behavioral change from heavy drinking. Currently, there is a lack of research examining the potential benefits of reduced alcohol consumption in chronic heavy drinkers, specifically in relation to different subtypes of CVD. We hypothesized that habitual changes in alcohol consumption among chronic heavy drinkers would have a long-term prognostic effect on future CVD outcomes. Purpose We investigated the association between reduced alcohol consumption and the risk of major adverse cardiovascular and cerebrovascular events (MACCE) in chronic heavy drinkers. Methods From the Korean National Health Insurance Service-Health Screening database, we included a cohort of chronic heavy drinkers who underwent serial health examinations over two consecutive time-periods (first period: 2005–2008; second period: 2009–2012). Heavy drinking was defined according to the National Institute on Alcohol Abuse and Alcoholism criteria as >56 g/day or >196 g/week for men, and >42 g/day or >98 g/week for women. Overall, 13,854 heavy drinkers at baseline (mean age 55.84 ± 5.98 years; 91.6 % men) were categorized into two groups based on the alcohol consumption changes in the second period: sustained heavy drinking (n=9,403; 67.9%) or reduced drinking (n=4,451; 32.5%). The primary outcome was MACCE, a composite of nonfatal myocardial infarction or angina undergoing revascularization, any stroke accompanied by hospitalization, and all-cause death during follow-up. Results In this nationwide population-based cohort study, during a total follow-up of 107,102 person-years, the sustained heavy drinking group experienced a significantly higher incidence of MACCE than the reduced drinking group (incidence rate, 825 vs. 655 per 100,000 person-years; log-rank p=0.004). Reduced alcohol consumption was associated with a 28% lower risk of MACCE compared to sustained heavy drinking (adjusted-hazard ratio [HR]: 0.780, 95% confidence interval [CI] 0.656–0.928). These benefits were mostly driven by a significant reduction in the incidence of angina (adjusted-HR: 0.631, 95% CI 0.425–0.926) and ischemic stroke (adjusted-HR: 0.657, 95% CI 0.472–0.914). The preventive effects of reduced alcohol intake were consistently observed across various subgroups of heavy drinkers, except for smoking status (p-interaction=0.015) and even after including abstainers in the sensitivity analysis. Conclusion Reduced alcohol consumption in heavy drinkers could lower the future risk of CVD, with the most pronounced benefits expected for stable/unstable angina and ischemic stroke. Further research is warranted to explore the optimal strategies for promoting sustained reductions in alcohol intake.Cumulative MACCE incidence curves

Alcohol consumption confers lasting impacts on prefrontal cortical neuron intrinsic excitability and spontaneous neurotransmitter signaling in the aging brain in mice

Both alcohol use disorder (AUD) and cognitive decline include disruption in the balance of excitation and inhibition in the cortex, but the potential role of alcohol use on excitation and inhibition on the aging brain is unclear. We examined the effect of moderate voluntary binge alcohol consumption on the aged, pre-disease neuronal environment by measuring intrinsic excitability and spontaneous neurotransmission on prefrontal cortical pyramidal (excitatory, glutamatergic) and non-pyramidal (inhibitory, GABAergic) neurons following a prolonged period of abstinence from alcohol in mice. Results highlight that binge alcohol consumption has lasting impacts on the electrophysiological properties of prefrontal cortical neurons. A profound increase in excitatory events onto layer 2/3 non-pyramidal neurons following alcohol consumption was seen, along with altered intrinsic excitability of pyramidal neurons, which could have a range of effects on cognitive disorder progression, such as Alzheimer’s Disease, in humans. These results indicate that moderate voluntary alcohol influences the pre-disease environment in aging and highlight the need for further mechanistic investigation into this risk factor.

Low to moderate ethanol exposure reduces astrocyte-induced neuroinflammatory signaling and cognitive decline in presymptomatic APP/PS1 mice

Alcohol use disorder has been associated with the development of neurodegenerative diseases, including Alzheimer’s disease (AD). However, recent studies demonstrate that moderate alcohol consumption may be protective against dementia and cognitive decline. We examined astrocyte function, low-density lipoprotein (LDL) receptor-related protein 1 (LRP1), and the NF-κB p65 and IKK-α/β signaling pathways in modulating neuroinflammation and amyloid beta (Aβ) deposition. We assessed apolipoprotein E (ApoE) in the brain of APP/PS1 mice using IHC and ELISA in response to low to moderate ethanol exposure (MEE). First, to confirm the intracerebral distribution of ApoE, we co-stained with GFAP, a marker for astrocytes that biosynthesize ApoE. We sought to investigate whether the ethanol-induced upregulation of LRP1 could potentially inhibit the activity of IL-1β and TNF-α induced IKK-α/β towards NF-κB p65, resulting in a reduction of pro-inflammatory cytokines. To evaluate the actual Aβ load in the brains of APP/PS1 mice, we performed with a specific antibody Aβ (Thioflavin S) on both air- and ethanol-exposed groups, subsequently analyzing Aβ levels. We also measured glucose uptake using 18F- fluorodeoxyglucose (FDG)-positron emission tomography (PET). Finally, we investigated whether MEE induced cognitive and memory changes using the Y maze, noble object recognition test, and Morris water maze. Our findings demonstrate that MEE reduced astrocytic glial fibrillary acidic protein (GFAP) and ApoE levels in the cortex and hippocampus in presymptomatic APP/PS1 mice. Interestingly, increased LRP1 protein expression was accompanied by dampening the IKK-α/β-NF-κB p65 pathway, resulting in decreased IL-1β and TNF-α levels in male mice. Notably, female mice show reduced levels of anti-inflammatory cytokines IL-4, and IL-10 without altering IL-1β and TNF-α concentrations. In both males and females, Aβ plaques, a hallmark of AD, were reduced in the cortex and hippocampus of APP/PS1 mice exposed to ethanol starting at pre-symptomatic stage. Consistently, MEE increased FDG-PET-based brain activities and normalized cognitive and memory deficits in the APP/PS1 mice. Our findings suggest that MEE may benefit AD pathology via modulating LRP1 expression, potentially reducing neuroinflammation and attenuating Aβ deposition. Our study implies that reduced astrocyte-derived ApoE and LDL cholesterol levels are critical for attenuating AD pathology.

To Drink or Not to Drink? Investigating Alcohol’s Impact on Prostate Cancer Risk

Background/Objectives: Prostate cancer (PCa) is a significant global health issue. The relationship between alcohol consumption and PCa risk has been the subject of extensive research, yet findings remain inconsistent. This review aims to clarify the association between alcohol intake and PCa risk, its aggressiveness, and the potential metabolic pathways involved in PCa onset. Methods: A comprehensive literature search was conducted across multiple databases, including PubMed and MEDLINE, focusing on epidemiological studies, meta-analyses, cohort studies, and case–control studies. Studies evaluating alcohol consumption, prostate-specific antigen (PSA) levels, and PCa risk were included. The review also explored the roles of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) in alcohol metabolism. Results: The analysis reveals a complex relationship between alcohol consumption and PCa. Heavy alcohol intake is associated with an increased risk of PCa, particularly more aggressive forms, and higher mortality rates. However, studies also show weak or no association between moderate alcohol consumption and PCa. The variability in findings may be attributed to differences in alcohol types, regional factors, and study methodologies. Conclusions: The link between alcohol consumption and PCa risk is multifaceted. While heavy drinking appears to increase the risk of aggressive PCa, the overall relationship remains unclear. Further research is needed to better understand these associations and inform public health recommendations and cancer prevention strategies.

Association of moderate alcohol intake with the risks of cirrhosis and steatotic liver disease: Results from a large population-based cohort study

Background&AimsThere is uncertainty about the associations between moderate alcohol consumption and liver-related outcomes. We aimed to explore the associations of moderate drinking with cirrhosis, steatotic liver disease (SLD), and liver cancer in a large cohort study. MethodsA total of 215,559 non-drinkers and moderate drinkers (< 20 g/day alcohol for females or < 30 g/day for males) were enrolled between 2006 and 2010 and followed up to 2022. The primary outcome is incident cirrhosis, and the secondary outcomes are the incidence of steatotic liver disease and liver cancer. Hazard ratios (HRs) and 95% confidence interval (CI) were calculated for liver-related outcomes in relation to moderate drinkers, as well as the quantity and type of their alcohol intake. All analyses were stratified by sex. ResultsA total of 705 cirrhosis, 2,010 SLD, and 350 liver cancer cases were documented during a median follow-up period of 12.7 years. Compared with non-drinkers, moderate drinkers had a lower risk of SLD (HR: 0.77; 95% CI: 0.66, 0.89). Among the moderate drinkers, alcohol intake [per standard deviation (SD) increment] was associated with an increased risk of incident cirrhosis (HR: 1.11; 95% CI: 1.02, 1.20), but the association was attenuated after restricting alcohol intake to no more than 16 g/day. Wine consumption (per SD increment of the percentage of wine consumption of total alcohol intake) had an inverse association with incident cirrhosis and SLD (HR: 0.82; 95% CI: 0.75, 0.89 for cirrhosis; HR: 0.91; 95% CI: 0.87, 0.96 for SLD). The inverse associations between moderate wine use and SLD were likely to be sex-dependent (P for interaction = 0.01). ConclusionsThe excessive alcohol threshold of 30 g/day for males may be set high for liver health. Further work is needed to make sex-specific recommendations on moderate drinking for liver health.

Cancer survivors' adherence to the American cancer society and American institute of cancer research dietary guidelines in Lebanon.

Adequate diet and lifestyle practices are postulated to improve health and enhance wellbeing of cancer survivors. Despite the heavy cancer burden in Lebanon, little is known about the diet quality of survivors. This cross-sectional study assessed the compliance of survivors in remission with the American Cancer Society/American Institute Research Fund (ACS/AICR) diet and physical activity guidelines. Cancer survivors in remission for at least 3 months and attending oncology clinics in two referral centers in Beirut, Lebanon were recruited. Adherence to the ACS/AICR was assessed by examining the compliance to guidelines promoting fruits, vegetables and whole grain and discouraging elevated alcohol, meat and energy dense foods intake. Dietary data was assessed through food frequency and lifestyle questionnaires administered face to face and through phone interviews. Anthropometrics, food security and sociodemographic data was also collected. Univariate and bivariate descriptive and logistic regressions were used to determine predictors of adherence rates to the ACS/AICR score. A total of 268 participants were recruited (mean age = 59 ± 23 years, 83% females, 70% breast cancer). Mean time since remission was 3.2 ± 4 years and the majority (72%) had food insecurity. Low physical activity and overweight/obesity were present in 65% and 67% of the survivors, respectively. Median adherence score with the ACS/AICR score was 9.0 out of 15. The majority of survivors had complete adherence to the moderate meat and alcohol consumption guidelines. However, 98% were noncompliant with the whole grains' consumption guidelines. Cancer type, site of recruitment and education were the significant predictors of the ACS/AICR diet adherence score. This study highlights the elevated rates of overweight/obesity, physical inactivity and the alarmingly low adherence with the whole grains consumption guideline among cancer survivors in remission. Policy makers ought to use study findings to redirect government subsidization and educational interventions in the country and physicians should stress the importance of adherence to a healthy diet during remission through counseling and timely referral.

Examining the causal association between moderate alcohol consumption and cardiovascular risk factors in the Taiwan Biobank: a Mendelian randomization analysis.

The Mendelian randomization approach uses genetic variants as instrumental variables to study the causal association between the risk factors and health outcomes of interest. We aimed to examine the relation between alcohol consumption and cardiovascular risk factors using two genetic variants as instrumental variables: alcohol dehydrogenase 1B (ADH1B) rs1229984 and aldehyde dehydrogenase 2 (ALDH2) rs671. Using data collected in the Taiwan Biobank-an ongoing, prospective, population-based cohort study-our analysis included 129,032 individuals (46,547 men and 82,485 women) with complete data on ADH1B rs1229984 and ALDH2 rs671 genotypes and alcohol drinking status. We conducted instrumental variables regression analysis to examine the relationship between alcohol drinking and body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose, glycated hemoglobin (HbA1c), triglycerides, high-density lipoprotein cholesterol (HDLc), and low-density lipoprotein cholesterol (LDLc). In the rs1229984-instrumented analysis, alcohol drinking was only associated with higher levels of SBP in men and lower levels of DBP in women. In the rs671-instrumented analysis, alcohol drinking was associated with higher levels of BMI, SBP, DBP, fasting glucose, triglycerides, HDLc and lower levels of LDLc in men; alcohol drinking was associated with higher levels of HDLc and lower levels of SBP, HbA1c, and triglycerides in women. Using Mendelian randomization analysis, some of our study results among men echoed findings from the previous systematic review, suggesting that alcohol drinking may be causally associated with higher levels of BMI, SBP, DBP, fasting glucose, triglycerides, HDLc, and lower levels of LDLc. Although alcohol drinking is beneficial to a few cardiovascular risk factors, it is detrimental to many others. The assumptions that underlie the Mendelian randomization approach should also be carefully examined when interpreting findings from such studies.

B-260 Prevalence and Relative Distributions of Major Phosphatidylethanol (PEth) Homologs in a Large-Scale Clinical Study

Abstract Background Ethanol abuse remains a significant public health challenge in the United States. Detection of ethanol exposure is crucial for preventive, diagnostic, and therapeutic endeavors. Phosphatidylethanol (PEth) is a specific and direct ethanol biomarker. Compared to other metabolites, such as ethyl glucuronide and ethyl sulfate in urine (average 2-3 days), PEth in blood has a longer window of detection (average 1-2 weeks). Among the known 48 PEth homologs, PEth 16:0/18:1 (POPEth) and PEth 16:0/18:2 (PLPEth) are the most abundant species accounting for 37% to 46% and 26% to 28%, respectively. PLPEth is synthesized at a greater rate than POPEth, but POPEth has a longer half-life than PLPEth. The purpose of this study was to understand the prevalence and levels of POPEth and PLPEth in a large number of clinical specimens. Methods Briefly, lavender-top whole blood specimens were diluted with isotopically labeled internal standard (IS) in an organic buffer to precipitate proteins on an automated Hamilton platform. The mixture was centrifuged, and a supernatant portion isolated for injection onto a Sciex QTRAP 5500 liquid chromatography tandem mass spectrometry (LC-MS/MS) system using electrospray ionization (ESI) in negative mode. The assay was fully validated under CLIA regulations for lab developed tests: the analytical measurement range (AMR) was 10-400 ng/mL; the administrative reporting threshold for PEth positivity was 20 ng/mL based on clinical literature and a consensus among other United States laboratory methods. Results Precision of 4 QC levels was evaluated with between-run CV% (n=25) ranging from 1.6-6.3%, and accuracy across the AMR was achieved with 87-110%. No significant matrix effects were observed; variation in different whole blood specimens was corrected with IS normalization. No significant interferences were observed from 137 commonly seen prescription and nonprescription drugs and 6 other PEth homologs. Of the clinical specimens, most (20,833, 71.3%) were negative (&amp;lt;20 ng/mL) for both analytes. Meanwhile, 8,222 specimens (28.3%) were positive with either POPEth, or PLPEth or both ≥ 20ng/mL. There were 150 specimens excluded from the statistics due to interference challenges. Interestingly, 757 specimens (2.6%) were PLPEth negative and POPEth positive (mean value 40.1 ng/mL). Conversely, 62 specimens (0.2%) were POPEth negative and PLPEth positive (mean value 24.6 ng/mL). Among the specimens with both POPEth and PLPEth levels within the AMR, the average POPEth/PLPEth ratio was 1.4 supporting the overall prevalence of higher POPEth concentrations than PLPEth. However, the POPEth/PLPEth ratio varied widely, from 0.3 to 8.8, reflecting patient differences in PEth metabolism patterns. Conclusions To help verify probable ethanol abstinence, we have developed, validated, and deployed a high-throughput clinical assay for the major PEth homologs, POPEth and PLPEth. In a retrospective analysis of 29,205 clinical specimens: 71.3% of results were consistent with abstinence; 28.3% of the results were positive suggesting moderate alcohol consumption within the last 1-2 weeks. With POPEth most prevalent, yet variation observed, there were 62 specimens with PLPEth positive and negative for POPEth. This clinical PEth study including both POPEth and PLPEth provides greater sensitivity to identify ethanol exposure than only testing a single homolog.

Modified 5-Item Frailty Index (mFI-5) may predict postoperative outcomes after pancreatoduodenectomy for pancreatic Cancer.

Pancreatic Ductal Adenocarcinoma (PDAC) primarily affects older individuals with diminished physiological reserves. The Modified 5-Item Frailty Index (mFI-5) is a novel risk stratification tool proposed to predict postoperative morbidity and mortality. This study aimed to validate the mFI-5 for predicting surgical outcomes in patients undergoing pancreatoduodenectomy (PD) for PDAC. Our retrospective PDAC database included patients who underwent PD between 2014 and 2023. Patients were stratified by mFI-5 scores (0 best - 5 worst), which assess preoperative CHF, diabetes mellitus, history of COPD or pneumonia, functional health status, and hypertension requiring medication. Associations between mFI-5 scores and outcomes, including postoperative complications and mortality, were analyzed using logistic regression, Cox proportional hazards models, and Kaplan-Meier survival analysis. Among 250 PDAC patients undergoing PD, 142 (56.8%) had mFI-5 scores ≤ 1, and 25 (10%) had scores ≥ 3. No patients had scores > 4. Higher mFI-5 scores correlated with older age (p < 0.001) and tobacco use (p = 0.036). Multivariate analysis identified age (RR 1.02, p = 0.038), ASA class (ASA III; RR 2.61, p < 0.001; ASA IV; RR 2.63, p = 0.026), and moderate alcohol consumption (RR 0.56, p = 0.038) as frailty predictors. An mFI-5 score > 2 independently associated with higher mortality (HR 2.08, p = 0.026). Median overall survival was significantly lower for patients with mFI-5 scores > 2 than for those with scores ≤ 2 (21.3 vs. 42.1 months, p = 0.022). The mFI-5 is a valuable tool for predicting postoperative morbidity and mortality in PDAC patients undergoing PD. Integrating frailty assessment into preoperative evaluations can enhance patient selection and surgical outcomes. Future research should focus on incorporating frailty assessments into surgical planning and patient management to improve outcomes in this vulnerable population.

Effects of moderate alcohol consumption and hypobaric hypoxia: implications for passengers’ sleep, oxygen saturation and heart rate on long-haul flights

BackgroundPassengers on long-haul flights frequently consume alcohol. Inflight sleep exacerbates the fall in blood oxygen saturation (SpO2) caused by the decreased oxygen partial pressure in the cabin. We investigated the...

Associations of socioeconomic status and healthy lifestyle with incident dementia and cognitive decline: two prospective cohort studies

Little is known about the complex associations of socioeconomic status (SES) and healthy lifestyle with cognitive dysfunction. Using data from the Health and Retirement Study (HRS) [2008-2020] and the English Longitudinal Study of Ageing (ELSA) [2004-2018], SES was constructed by latent class analysis using education level, total household income and wealth. Overall healthy lifestyle was derived using information on never smoking, low to moderate alcohol consumption (drinks/day: (0, 1] for women and (0, 2] for men), top tertile of physical activity, and active social contact. A total of 12,437 and 6565 participants from the HRS and ELSA were included (40.8% and 46.0% men and mean age 69.3 years and 65.1 years, respectively). Compared with participants of high SES, those of low SES had higher risk of incident dementia (hazard ratio 3.17, 95% confidence interval 2.72-3.69 in the HRS; 1.43, 1.09-1.86 in the ELSA), and the proportions mediated by overall lifestyle were 10.4% (7.3%-14.6%) and 2.7% (0.5%-14.0%), respectively. Compared with participants of high SES and favorable lifestyle, those with low SES and unfavorable lifestyle had a higher risk of incident dementia (4.27, 3.40-5.38 in the HRS; 2.02, 1.25-3.27 in the ELSA) and accelerated rate of global cognitive decline (β=-0.058 SD/year; 95% CI:-0.073,-0.043 in the HRS; β=-0.049 SD/year; 95% CI:-0.063,-0.035 in the ELSA). Unhealthy lifestyle only mediated a small proportion of the socioeconomic inequality in dementia risk in both US and UK older adults.

Cardiac rehabilitation for patients with coronary artery disease

Background: Coronary artery disease (CAD) is the leading cause of death in Korea, with high rates of recurrence and mortality associated with relapse. Therefore, various strategies are required to prevent recurrent CAD. Cardiac rehabilitation (CR) is proven to be safe and highly effective and is therefore considered essential treatment for secondary prevention of CAD. CR is reimbursed in Korea since February 2017.Current Concepts: CR comprises the following main components: education, evaluation, and treatment. CR education includes increasing awareness regarding the chronic risk factors associated with CAD and motivating patients to manage these factors independently. Such management includes smoking cessation, moderation in alcohol consumption, weight management, maintenance of physical activity, medication adherence, and psychosocial interventions. CR evaluation through cardiopulmonary exercise tests is useful to predict prognosis and provides basic information for exercise prescriptions. CR treatment includes prescription of a personalized exercise program, with aerobic exercise as the main component supported by resistance training.Discussion and Conclusion: CR is an important treatment modality that significantly improves exercise capacity while reducing readmission rates and mortality in patients with CAD . Therefore, it is essential to understand CR methods and concepts and encourage patients with CAD to participate in CR programs.

Alcohol Consumption and Cardiovascular Disease: A Narrative Review of Evolving Perspectives and Long-Term Implications.

Cardiovascular illnesses remain the primary cause of death, accounting for at least 17.9 million fatalities per year and posing a significant public health problem because of its extensive predominance and effect on healthcare systems. The etiology of cardiovascular disease is complex and involves several environmental and lifestyle factors. Alcohol use is a highly important determinant because of its dual-edged effect on cardiovascular health. Multiple studies indicate that moderate alcohol consumption may have certain advantages, such as slight enhancements in lipid profiles. Conversely, excessive alcohol intake is associated with serious negative consequences, including cardiomyopathy, hypertension, arrhythmias, and even mortality. The aim of this study is to provide a comprehensive analysis of the several effects of alcohol on cardiovascular health and their understanding within the medical field over time. It uses an interpretative narrative review methodology and analyzes studies that focus on genetic risk factors, gender differences, and shifts in paradigms in recent years. This article highlights the need for obtaining a thorough understanding of the effects of alcohol on cardiovascular health to support public health guidelines and clinical practice, and it underscores the significance of including alcohol consumption into the broader context of cardiovascular risk management and identifies important subjects for further study.

The Interaction Effects of Sex, Age, APOE and Common Health Risk Factors on Human Brain Functions.

Nonlinear changes in brain function during aging are shaped by a complex interplay of factors, including sex, age, genetics, and modifiable health risk factors. However, the combined effects and underlying mechanisms of these factors on brain functional connectivity remain poorly understood. To comprehensively investigate the combined associations of sex, age, APOE genotypes, and ten common modifiable health risk factors with brain functional connectivities during aging. This analysis used data from 36,630 UK Biobank participants, aged 44-81, who were assessed for sex, age, APOE genotypes, 10 health risk factors, and brain functional connectivities through resting-state functional magnetic resonance imaging. Brain functional connectivities were evaluated through within- and between-network functional connectivities and connectivity strength. Associations between risk factors and brain functional connectivities, including their interaction effects, were analyzed. Hypertension, BMI, and education were the top three influential factors. Sex-specific effects were also observed in interactions involving APOE4 gene, smoking, alcohol consumption, diabetes, BMI, and education. Notably, a negative sex-excessive alcohol interaction showed a stronger negative effect on functional connectivities in males, particularly between the dorsal attention network and the language network, while moderate alcohol consumption appeared to have protective effects. A significant negative interaction between sex and APOE4 revealed a greater reduction in functional connectivity between the cingulo-opercular network and the posterior multimodal network in male APOE4 carriers. Additional findings included a negative age-BMI interaction between the visual and dorsal attention networks, and a positive age-hypertension interaction between the frontoparietal and default mode networks. The findings highlight significant sex disparities in the associations between age, the APOE-ε4 gene, modifiable health risk factors, and brain functional connectivity, emphasizing the necessity of jointly considering these factors to gain a deeper understanding of the complex processes underlying brain aging.

Association Between Alcohol Consumption and Disability Accumulation in Multiple Sclerosis.

Previous studies have indicated that alcohol consumption is associated with multiple sclerosis (MS) disease progression. We aimed to study the influence of alcohol consumption habits on disease progression and health-related quality of life in MS. We categorized patients from 2 population-based case-control studies by alcohol consumption habits at diagnosis and followed them up to 15 years after diagnosis through the Swedish MS registry regarding changes in the Expanded Disability Status Scale (EDSS) and Multiple Sclerosis Impact Scale 29 (MSIS-29). We used Cox regression models with 95% confidence intervals (CIs) using 24-week confirmed disability worsening, EDSS 3, EDSS 4, and physical and psychological worsening from the patient's perspective as end points. Our study comprised 9,051 patients with MS, with a mean age of 37.5 years at baseline/diagnosis. Compared with nondrinking, low and moderate alcohol consumption was associated with reduced risk of EDSS-related unfavorable outcomes (hazard ratios between 0.81 and 0.90) and with reduced risk of physical worsening. The inverse association was confined to relapsing-remitting MS and was more pronounced among women. High alcohol consumption did not significantly affect disease progression. The inverse relationship between low-moderate alcohol consumption and disability progression became stronger when we only included those who had not changed their alcohol consumption during follow-up (hazard ratios between 0.63 and 0.71). There were no differences in measures of disability at baseline between drinkers who continued drinking alcohol after diagnosis and those who later discontinued. Our findings speak against bias due to reverse causation. Low and moderate alcohol consumption was associated with more favorable outcomes in relapsing-remitting MS, compared with nondrinking, while there was no significant influence of high alcohol consumption on disease outcomes.

Alcohol consumption and frailty risk: a dose-response meta-analysis of cohort studies.

While previous studies suggest that light-to-moderate alcohol consumption may reduce the frailty risk, the dose-response relationship is still under question. To address the knowledge gap, we conducted a systematic review and dose-response meta-analysis of cohort studies to examine the association of alcohol consumption with the risk of both prefrailty and frailty in adults. We searched MEDLINE (Ovid), PubMed and Scopus to identify relevant cohort studies published before 8 May 2024. The dose-response meta-analysis was performed to investigate the associations between alcohol drinking and the risk of developing pre-frailty and frailty. We used random-effects models to calculate pooled relative risks (RR) with 95% CIs. We included nine cohort studies with 64 769 participants and 15 075 cases, of which eight studies were rated to have a serious risk of bias as assessed by the ROBINS tool. Based on our analysis, each 12g increase in alcohol intake did not appear to be associated with risks of prefrailty (RR: 1.08, 95% CI 0.89, 1.31; I2= 91%, n = 3; GRADE = very low) and frailty (RR: 0.94, 95% CI 0.88, 1.00; I2= 63%, n = 9; GRADE = low). The nonlinear dose-response meta-analysis indicates a slight inverse association with frailty risk up to an alcohol intake of 20 grams per day, beyond which an upward trend is observed. The inverse association found between moderate alcohol consumption and frailty risk appears to be stronger among older adults, which might be due to the lower and less popular alcohol consumption among older people than the general population. However, because this finding is based on low-quality evidence, more research is needed to develop specific dietary recommendations for alcohol consumption, particularly among young people.

Nutrigenetics and Nutritional Strategies in Systemic Arterial Hypertension: Evidence From a Scoping Review.

Nutrition and genetics have individual roles in systemic arterial hypertension (SAH); however, they can interact, influencing the regulation of blood pressure (BP) levels. The aim of this study was to evaluate the available evidence regarding gene-nutrient interactions in modulating BP levels in adults with SAH. The review followed the recommendations of the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Twelve studies met the inclusion criteria for this review, reporting on 20 genes and 31 single nucleotide polymorphisms (SNPs), with 19 of them associated with BP variations. The most frequently evaluated SNPs were ACE rs4646994 and AT1R rs5186. Among the nutritional interventions, dietary sodium content was the focus of most studies (n = 11). Interactions with sodium consumption were observed for the following SNPs: KDM1A rs587168, EDNRB rs5351, LSS rs2254524, IRS1 rs1801278, KCNK9 rs6997709, ACE rs4646994, GNB3 rs5443, PPARG rs4684847, EDN1 rs5370, BCAT1 rs7961152, IL18 rs5744292, NOS3 rs2070744, and AT1R rs5186. In the presence of a diet rich in fruits and vegetables, moderate alcohol consumption, and reduced sodium intake, the SNP AT2R rs11091046 was associated with a decrease in BP levels. Furthermore, the SNP MTHFR rs1801133 exhibited an interaction with riboflavin supplementation in affecting BP levels. The evidence regarding the interaction between genetics and diet on BP levels remains limited. Among the existing findings, an interaction was observed between sodium, calcium, riboflavin, and specific polymorphisms; however, the underlying mechanisms for these interactions have yet to be identified.

Evaluation and comparison of sensitivity of alcohol biomarkers PEth, EtG and EtPa in civil cases in England 2022–2023

This study details trends in direct alcohol biomarker concentrations from civil cases within the United Kingdom (UK). Our subject cohort in this study related to family law litigation, where an individual was subject to an alcohol monitoring order by the court. This monitoring was conducted by quantification of alcohol biomarkers Phosphatidlyethanol (PEth) in dried blood spots (DBS) and Ethyl Glucuronide (EtG) and Ethyl Palmitate (EtPa) from hair segments. In total 298 PEth cases predominantly from the South East of England during the period July 2022 to August 2023 were analysed for alcohol biomarkers in DBS and hair. Subjects alcohol intake was classified as abstinence/low alcohol consumption, moderate or excessive alcohol consumption, based on a combination of Society for Hair Testing and PEth Net guidelines. Our results indicate that 33 % of PEth concentrations were consistent with excessive alcohol use (>200 ng/mL DBS), with 36 % consistent with social or moderate alcohol use (20–200 ng/mL DBS). In relation to EtG and EtPa 23 % and 31 % of subjects were classified as excessive alcohol users respectively. This study indicates that DBS sampling of PEth is a more sensitive predictor of alcohol use, in particular, at differentiating between moderate and excessive alcohol use compared to EtG and EtPa testing in hair. The authors suggest that increased frequency in the sampling of PEth in DBS (multiple occasions per month) may provide a more accurate assessment and simplification of the interpretation criteria of alcohol patterns rather than the combined hair testing and DBS sampling that are typically requested by UK courts.
