Alcohol Consumption, Diabetes Risk, and Cardiovascular Disease Within Diabetes

Who is asked about alcohol consumption? A retrospective cohort study using a national repository of Electronic Medical Records

Documentation of alcohol use in electronic medical record (EMR) informs interventions to reduce alcohol-related morbidity and mortality. This retrospective cohort study explored EMR data from 960 primary care providers participating in the Canadian Primary Care Sentinel Surveillance Network to describe documentation of alcohol use (e.g. none, current or past use) in the EMR. Included providers represented 700,620 adult patients from across Canada with an encounter between 2015 and 2018. Bivariate comparisons characterized the patients with, and without, documentation of alcohol use. Multivariate generalized estimating equation models with logit function assessed patient and provider characteristics associated with (1) documentation of alcohol and (2) patients with heightened risk for alcohol-related problems. Forty percent of patients had alcohol use documentation in the EMR. Light alcohol consumption was recorded for 43.6% of these patients. Male patients (OR1.09, CI 1.07-1.12), who were older (OR1.26, CI 1.23-1.30), had more frequent visits to their provider (OR1.11, CI 1.09-1.13) and had hypertension (OR1.07, CI 1.06-1.09) or depression (OR1.07, CI 1.09-1.14) had higher odds of alcohol documentation. There were 4.7% of patients with a record indicating heightened risk for alcohol-related problems. Male patients (OR3.27 CI 3.14-3.4), patients with depression (OR2.01 CI1.93-2.1) and rural residency (OR1.35 CI1.29-1.42) was associated with risk for alcohol-related problems. Heavy alcohol consumption is associated with an increased risk of negative health outcomes, particularly for patients with certain chronic conditions. However, these patients do not have alcohol use consistently documented in the EMR. Strategies should be designed and implemented to support more consistent alcohol-screening among high-risk patients.

Moderate Consumption of Beer and Its Effects on Cardiovascular and Metabolic Health: An Updated Review of Recent Scientific Evidence

There is growing interest in the potential health-related effects of moderate alcohol consumption and, specifically, of beer. This review provides an assessment of beer-associated effects on cardiovascular and metabolic risk factors to identify a consumption level that can be considered “moderate”. We identified all prospective clinical studies and systematic reviews that evaluated the health effects of beer published between January 2007 and April 2020. Five of six selected studies found a protective effect of moderate alcohol drinking on cardiovascular disease (beer up to 385 g/week) vs. abstainers or occasional drinkers. Four out of five papers showed an association between moderate alcohol consumption (beer intake of 84 g alcohol/week) and decreased mortality risk. We concluded that moderate beer consumption of up to 16 g alcohol/day (1 drink/day) for women and 28 g/day (1–2 drinks/day) for men is associated with decreased incidence of cardiovascular disease and overall mortality, among other metabolic health benefits.

Executive summary: Updates to the dietary treatment of prediabetes and type 2 diabetes mellitus

Adequate lifestyle changes significantly reduce the cardiovascular risk factors associated with prediabetes and type 2 diabetes mellitus. Therefore, healthy eating habits, regular physical activity, abstaining from using tobacco, and good sleep hygiene are recommended for managing these conditions. There is solid evidence that diets that are plant-based; low in saturated fatty acids, cholesterol, and sodium; and high in fiber, potassium, and unsaturated fatty acids are beneficial and reduce the expression of cardiovascular risk factors in these subjects. In view of the foregoing, the Mediterranean diet, the DASH diet, a low-carbohydrate diet, and a vegan-vegetarian diet are of note. Additionally, the relationship between nutrition and these metabolic pathologies is fundamental in targeting efforts to prevent weight gain, reducing excess weight in the case of individuals with overweight or obesity, and personalizing treatment to promote patient empowerment. This document is the executive summary of an updated review that includes the main recommendations for improving dietary nutritional quality in people with prediabetes or type 2 diabetes mellitus.

Prevalence of Cardiovascular Disease and Associated Factors Among Type 2 Diabetes Patients in Selected Hospitals of Harari Region, Eastern Ethiopia

Background: Cardiovascular disease (CVD) is the most prevalent complication and the leading cause of death among patients with diabetes mellitus (DM). Type 2 diabetes mellitus (T2DM) patients have a 2- to 4-fold increased risk of CVD. There is a scarcity of data about the magnitude of CVD among patients with diabetes in Ethiopia. This study aimed to assess the prevalence and associated factors of CVD among T2DM patients at selected hospitals of Harari regional state of Ethiopia. Methods: This hospital-based retrospective data review was conducted among T2DM patients on follow-up in the diabetes clinics of selected hospitals of Harari regional state. The records of T2DM patients who have been diagnosed between January 1, 2013, and December 31, 2017, were reviewed from March to April 2018. Data were collected by using structured checklists from all necessary documents of T2DM patients. Statistical analysis was done using STATA 14.1. Bivariate and multivariate logistic regressions were used to identify factors associated with CVD. Result: The records of 454 T2DM patients were extracted from three government hospitals in Harari regional state. Their age was ranging from 15 to 86 years with a mean age (±SD) of 45.39 (14.76). The overall prevalence of CVD among T2DM patients was 42.51%, composed of hypertensive heart diseases (38.99%), heart failure (6.83%), and stroke (2.20%). The final multivariate logistic regression model revealed that age older than 60 years [adjusted odds ratio (AOR) = 3.22; 95% CI: 1.71-6.09], being physically inactive (AOR = 1.45; 95 CI: 1.06-2.38), drinking alcohol (AOR = 2.39; 95% CI: 1.17-6.06), hypertension (AOR = 2.41; 95% CI: 1.52-3.83), body mass index >24.9 kg/m2 (AOR = 1.81; 95% CI: 1.07-3.07), and experiencing microvascular diabetic complications (AOR = 3.62; 95% CI: 2.01-6.53) were significantly associated with the odds of having CVD. Conclusion: The prevalence of CVD was high and associated with advanced age, physical inactivity, drinking alcohol, higher body mass index, hypertension, and having microvascular complications. Health care workers should educate T2DM patients about healthy lifestyles like physical activity, weight reduction, blood pressure control, and alcohol secession, which can reduce the risk of CVD.

Associations of Smoking and Drinking with New Lipid-Related Indices in Women with Hyperglycemia

Background: Lipid-related indices are useful for early detection of the risk of cardiovascular disease. The relationships of smoking and alcohol drinking with lipid-related indices in women with diabetes remain to be clarified. Methods: In female participants with hyperglycemia, four lipid-related indices, ratio of low-density lipoprotein cholesterol to high-density lipoprotein cholesterol (LDL-C/HDL-C ratio), atherogenic index of plasma (AIP), lipid accumulation product (LAP), and cardiometabolic index (CMI), were compared in smokers and nonsmokers and in occasional drinkers, regular drinkers, and nondrinkers. Analysis of covariance and logistic regression analysis were used for comparison with adjustment for age, hemoglobin A1c, history of regular exercise, and history of alcohol drinking or smoking. Results: Mean levels of LDL-C/HDL-C ratio, AIP, and CMI were significantly higher in smokers than in nonsmokers, and the odds ratios in smokers versus nonsmokers for high LDL-C/HDL-C ratio, high AIP, and high CMI were significantly higher than the reference level. These differences in mean levels and odds ratios were not found in analysis of LAP. Mean levels of LDL-C/HDL-C ratio, LAP, AIP, and CMI were significantly lower in regular drinkers than in nondrinkers. The odds ratios versus nondrinkers for high LDL-C/HDL-C ratio, high AIP, high LAP, and high CMI in regular drinkers were significantly lower than the reference level. The odds ratios versus nondrinkers for high LDL-C/HDL-C ratio, high LAP, and high CMI in occasional drinkers were also significantly lower than the reference level. Conclusions: In women with hyperglycemia, smoking was positively associated with LDL-C/HDL-C ratio, AIP, and CMI, and habitual alcohol drinking was inversely associated with LDL-C/HDL-C ratio, AIP, LAP, and CMI. Thus, LDL-C/HDL-C ratio, AIP, and CMI are thought to be affected by both smoking and alcohol drinking, which accelerates and suppresses atherosclerotic progression, respectively.

COVID-19 and alcohol in Mexico: A serious health crisis, strong actions on alcohol in response-Commentary on Stockwell et al

The present text comments on Stockwell and colleagues' paper documenting the high burden of alcohol use in COVID-19 related mortality in the USA and Canada in North America and the absence of a control policy in several countries of the world. This comment adds information about the third country in North America, Mexico. It describes alcohol use during the COVID lockdown and its consequences, highlighting the control efforts through public health policies and ponders the weaknesses of the current response to the health crisis and opportunities in the aftermath.

Preconception Alcohol Exposure Increases the Susceptibility to Diabetes in the Offspring

Heavy alcohol drinking alters glucose metabolism, but the inheritability of this effect of alcohol is not well understood. We used an animal model of preconception alcohol exposure in which adult female rats were given free access to 6.7% alcohol in a liquid diet and water for about 4 weeks, went without alcohol for 3 weeks, and then were bred to generate male and female offspring. Control animals were either ad lib-fed rat chow or pair-fed an isocaloric liquid diet during the time of alcohol-feeding in the experimental animals. Our results show that the female rats fed with alcohol in the liquid diet, but not with the isocaloric liquid diet, prior to conception had an altered stress gene network involving glucose metabolism in oocytes when compared with those in ad lib-fed chow diet controls. The offspring born from preconception alcohol-fed mothers showed significant hyperglycemia and hypoinsulinemia when they were adults. These rats also showed increased levels of inflammatory cytokines and cellular apoptosis in the pancreas, altered insulin production and actions in the liver, and a reduced number of proopiomelanocortin neurons in the hypothalamus. Replenishment of proopiomelanocortin neurons in these animals normalized the abnormal glucose to restore homeostasis. These data suggest that preconception alcohol exposures alter glucose homeostasis by inducing proopiomelanocortin neuronal functional abnormalities. Our findings provide a novel insight into the impact of high doses of alcohol on the female gamete that may cause inheritance of an increased susceptibility to diabetes.

Interventions to prevent periodontal disease in tobacco-, alcohol-, and drug-dependent individuals

Substance abuse affects more than one sixth of the world's population. More importantly, the nature of the abuse and the type of addictive substances available to individuals is increasing exponentially. All substances with abusive potential impact both the human immuno-inflammatory system and oral microbial communities, and therefore play a critical role in the etiopathogenesis of periodontal diseases. Evidence strongly supports the efficacy of professionally delivered cessation counseling. Dentists, dental therapists, and hygienists are ideally placed to deliver this therapy, and to spearhead efforts to provide behavioral and pharmacologic support for cessation. The purpose of this review is to examine the biologic mechanisms underlying their role in disease causation, to understand the pharmacologic and behavioral basis for their habituation, and to investigate the efficacy of population-based and personalized interventions in prevention of periodontal disease.

Association of Alcohol Consumption and Ideal Cardiovascular Health Among South Asians: The Mediators of Atherosclerosis in South Asians Living in America (MASALA) Study

BACKGROUND

Observational studies have shown that alcohol consumption above the recommended limit is associated with increased cardiovascular disease (CVD), although its association in South Asians is unclear. Less is known regarding the association between alcohol consumption and cardiovascular health (CVH), assessed by the American Heart Association's Life's Simple 7 (LS7) health metrics among those with South Asian ancestry.

METHODS

This analysis included 701 participants without CVD from the Mediators of Atherosclerosis in South Asians Living in America (MASALA) cohort (2015 to 2018). Based on a personal history questionnaire, participants were divided into never, former, and current drinkers. The current drinking category was further classified into 1 to 3 drinks/wk, 4 to 7 drinks/wk, and >7 drinks/wk. The consumption of 5 or more drinks on 1 occasion in the past month was defined as binge drinking. Each LS7 component was given a point score of 0, 1, or 2. The total score was categorized into 0 to 6, 7 to 10, and 11 to 14 to represent poor, intermediate, and ideal CVH, respectively. We use multinomial logistic regression to examine the association between alcohol consumption and CVH.

RESULTS

In the MASALA cohort (mean age = 59 years, 43% female), participants consuming >7 drinks/wk had the lowest mean CVH score. Compared with never drinkers, male participants consuming >7 drinks/wk were less likely to have intermediate CVH (0.44 [0.08, 0.91]) and ideal CVH (0.23 [0.03, 0.96]). Binge drinking was associated with significantly lower odds of ideal CVH compared with never drinkers.

CONCLUSION

We found evidence of an inverse association of moderate to heavy alcohol consumption and ideal CVH in South Asian men. These findings further underscore the important relationship between alcohol consumption and CVH in this unique population of South Asians.

A nomogram model for screening the risk of diabetes in a large-scale Chinese population: an observational study from 345,718 participants

Our study is major to establish and validate a simple type||diabetes mellitus (T2DM) screening model for identifying high-risk individuals among Chinese adults. A total of 643,439 subjects who participated in the national health examination had been enrolled in this cross-sectional study. After excluding subjects with missing data or previous medical history, 345,718 adults was included in the final analysis. We used the least absolute shrinkage and selection operator models to optimize feature selection, and used multivariable logistic regression analysis to build a predicting model. The results showed that the major risk factors of T2DM were age, gender, no drinking or drinking/time > 25 g, no exercise, smoking, waist-to-height ratio, heart rate, systolic blood pressure, fatty liver and gallbladder disease. The area under ROC was 0.811 for development group and 0.814 for validation group, and the p values of the two calibration curves were 0.053 and 0.438, the improvement of net reclassification and integrated discrimination are significant in our model. Our results give a clue that the screening models we conducted may be useful for identifying Chinses adults at high risk for diabetes. Further studies are needed to evaluate the utility and feasibility of this model in various settings.

Microbiota and Lifestyle: A Special Focus on Diet

It is widely known that a good balance and healthy function for bacteria groups in the colon are necessary to maintain homeostasis and preserve health. However, the lack of consensus on what defines a healthy gut microbiota and the multitude of factors that influence human gut microbiota composition complicate the development of appropriate dietary recommendations for our gut microbiota. Furthermore, the varied response to the intake of probiotics and prebiotics observed in healthy adults suggests the existence of potential inter- and intra-individual factors, which might account for gut microbiota changes to a greater extent than diet. The changing dietary habits worldwide involving consumption of processed foods containing artificial ingredients, such as sweeteners; the coincident rise in emotional disorders; and the worsening of other lifestyle habits, such as smoking habits, drug consumption, and sleep, can together contribute to gut dysbiosis and health impairment, as well as the development of chronic diseases. This review summarizes the current literature on the effects of specific dietary ingredients (probiotics, prebiotics, alcohol, refined sugars and sweeteners, fats) in the gut microbiota of healthy adults and the potential inter- and intra-individual factors involved, as well as the influence of other potential lifestyle factors that are dramatically increasing nowadays.

Incidence of cancer and mortality among heavy alcoholics

BACKGROUND AND AIMS

Cancer risk is increased in alcoholics. Heavy ethanol consumption is also associated with other potentially lethal conditions such as cirrhosis, diabetes, hypertension, dyslipidemia or malnutrition, that increase mortality. The aim of the present study is to analyze the impact on mortality of new cancer development in a cohort of heavy alcoholics.

METHODS

Three hundred and thirty nine heavy alcoholics (about 200 g ethanol/daily during more than 15 years), initially admitted for organic problems to our service (reference hospital) were prospectively followed up for a maximum period of 120 months (median = 26, interquartile range = 12-60 months), either as outpatients or during successive admissions. Clinical and laboratory evaluation including incidence of new cancer and drinking habits were recorded at each appointment, as well as mortality.

RESULTS

During the study period 57 patients developed cancer and 151 died. Only 75 did not relapse in alcohol drinking. Mortality was related to deranged liver function, relapse of alcohol drinking, and malnutrition, whereas age, the development of new cancer, or the presence of diabetes, dyslipidemia or hypertension did not influence on mortality, especially in cirrhotics and among those who did not quit drinking. Cancer was related to mortality only among non-cirrhotics, together with ethanol abstention and age.

CONCLUSIONS

Heavy drinking is associated with high mortality among alcoholic patients admitted to the hospital. If a patient is already cirrhotic or if there is drinking relapse, the development of a new cancer, the concurrent presence of diabetes, hypertension, dyslipidemia, or advanced age have no impact on survival. Mortality is only related to deranged liver function, relapse of alcohol drinking, and malnutrition.

Oxidative stress inhibition by resveratrol in alcohol-dependent mice

OBJECTIVES

Uncontrolled ingestion of alcohol has dramatic consequences on the entire organism that are also associated with the oxidation process induced by alcohol and elevate radical oxygen species. Resveratrol, a nonflavonoid phenol, shows well-documented antioxidant properties. We investigated the potential antioxidant ability of this natural compound in a mouse model of alcohol addiction.

METHODS

We administered (per os) for 60 d 10 mg · kg^-1 · d^-1 of resveratrol in alcoholic adult male mice. Oxidative stress was evaluated by measuring serum-free oxygen radicals defense and free oxygen radical levels. Resveratrol metabolites were measured in the serum of mice that were administered with resveratrol. Finally, the effect of resveratrol on the alcohol-induced alteration of brain-derived neurotrophic factors (BDNF) in the liver was investigated.

RESULTS

Prolonged consumption of resveratrol strongly counteracts serum radical oxygen species formation caused by chronic alcohol intake without effects on natural, free oxygen radical defense. The presence of resveratrol metabolites in the serum only of animals supplemented with resveratrol potentiates the evidence that the antioxidant effect observed is due to the ingestion of the natural compound. Moreover, resveratrol supplementation can counteract alcohol-induced BDNF elevation in the liver, which is the main target of organ alcohol-induced damage.

CONCLUSIONS

The consumption of resveratrol through metabolite formation may play a protective role by decreasing free radical formation and modulating the BDNF involved in hepatic disruption induced by chronic alcohol consumption. Further investigation into the mechanism underlying the protective effect could reinforce the potential use of resveratrol as a dietary supplement to prevent damage associated with chronic alcohol abuse.

Inverse association between habitual alcohol drinking and d-dimer in patients with type 2 diabetes mellitus

Alcohol is known to inhibit blood coagulation. Patients with diabetes mellitus are prone to show hypercoagulability. However, it remains to be clarified whether and how habitual alcohol drinking affects coagulability in patients with diabetes. The purpose of this study was to determine the relationship between alcohol intake and d-dimer, a sensitive marker of blood coagulation, in patients with diabetes. We investigated the relationship between alcohol intake and d-dimer in plasma of 269 patients with type 2 diabetes by using analysis of covariance and logistic regression analysis after adjustment for age, gender, body mass index, hemoglobin A1c, and histories of smoking and anti-coagulation therapy. Log-transformed d-dimer and HDL cholesterol were significantly lower and higher, respectively, in regular drinkers than in nondrinkers, while there were no significant differences in log-transformed d-dimer and HDL cholesterol in occasional drinkers and nondrinkers. Odds ratios of regular drinkers vs. nondrinkers for high d-dimer (0.46 [0.21-0.98]) and low HDL cholesterol (0.20 [0.08-0.50]) were significantly lower than the reference level, while the odds ratios of occasional drinkers for high d-dimer (1.24 [0.41-3.73]) and low HDL cholesterol (0.43 [0.15-1.25]) were not significantly different from the reference level. HDL cholesterol showed a significant inverse correlation with log-transformed d-dimer both in overall subjects and in nondrinkers. Regular drinking, but not occasional drinking, was associated with lower d-dimer levels, suggesting that habitual alcohol drinking suppresses hypercoagulability in patients with diabetes. There is an alcohol intake-independent inverse association between HDL cholesterol and d-dimer.

Analysis of the relationship between lifestyle habits and glycosylated hemoglobin control based on data from a Health Management Plan

BACKGROUND/OBJECTIVES

Type 2 Diabetes mellitus (T2DM) is a hereditary disease that is also strongly dependent on environmental factors, lifestyles, and dietary habits. This study explored the relationship between lifestyle habits and glycosylated hemoglobin management in T2DM patients to provide empirical outcomes to improve T2DM management and patient health literacy.

SUBJECTS/METHODS

This study enrolled 349 diabetic patients with more than 5 care visits to a Diabetes Mellitus care network under the Health Management Plan led by Taiwan Department of Health (DOH). Based on relevant literature, an Outpatient Record Form of Diabetes Mellitus Care was designed and lipid profile tests were conducted for data collection and analysis.

RESULTS

When modeling the data, the results showed that the odds for HbA1c > 7.5% in T2DM patients duration over 10 years was 3.785 (P = 0.002) times that in patients with disease duration of fewer than 3 years. The odds of HbA1c > 7.5% in illiterate patients was 3.128 (P = 0.039) times that in patients with senior high school education or above. The odds of HbA1c > 7.5% in patients with other chronic illness was 2.207 (P = 0.019) times that in participants without chronic illness. Among 5 beneficial lifestyle habits, the odds of HbA1c > 7.5% in patients with 2 or 3 good habits were 3.243 (P = 0.003) and 3.424 (P = 0.001) times that in patients with more than 3 good habits, respectively.

CONCLUSION

This empirical outcome shows that maintaining a good lifestyle improves T2DM management and patients' knowledge, motivation, and ability to use health information. Patients with longer disease duration, education, or good lifestyle habits had optimal HbA1c management than those in patients who did not. Thus, effective self-management and precaution in daily life and improved health literacy of diabetic patients are necessary to increase the quality of T2DM care.

Identification of Potential Type II Diabetes in a Large-Scale Chinese Population Using a Systematic Machine Learning Framework

BACKGROUND

An estimated 425 million people globally have diabetes, accounting for 12% of the world's health expenditures, and the number continues to grow, placing a huge burden on the healthcare system, especially in those remote, underserved areas.

METHODS

A total of 584,168 adult subjects who have participated in the national physical examination were enrolled in this study. The risk factors for type II diabetes mellitus (T2DM) were identified by p values and odds ratio, using logistic regression (LR) based on variables of physical measurement and a questionnaire. Combined with the risk factors selected by LR, we used a decision tree, a random forest, AdaBoost with a decision tree (AdaBoost), and an extreme gradient boosting decision tree (XGBoost) to identify individuals with T2DM, compared the performance of the four machine learning classifiers, and used the best-performing classifier to output the degree of variables' importance scores of T2DM.

RESULTS

The results indicated that XGBoost had the best performance (accuracy = 0.906, precision = 0.910, recall = 0.902, F-1 = 0.906, and AUC = 0.968). The degree of variables' importance scores in XGBoost showed that BMI was the most significant feature, followed by age, waist circumference, systolic pressure, ethnicity, smoking amount, fatty liver, hypertension, physical activity, drinking status, dietary ratio (meat to vegetables), drink amount, smoking status, and diet habit (oil loving).

CONCLUSIONS

We proposed a classifier based on LR-XGBoost which used fourteen variables of patients which are easily obtained and noninvasive as predictor variables to identify potential incidents of T2DM. The classifier can accurately screen the risk of diabetes in the early phrase, and the degree of variables' importance scores gives a clue to prevent diabetes occurrence.

Alcohol intake and periodontitis in adults aged ≥30 years: NHANES 2009-2012

BACKGROUND

Whether an association between alcohol consumption and periodontitis exists is still unclear. This study aimed to assess the association between alcohol consumption and periodontitis.

METHODS

7062 adults 30 years or older who participated in 2009-2010 and 2011-2012 cycles of the National Health and Nutrition Examination Survey (NHANES) were included. Alcohol consumption measurement included self-reported average number of alcoholic drinks per week over the previous 12 months and was categorized into four groups (0, < 1, 1- < 8, and ≥8 drinks per week). Participants were categorized using surveillance case definitions for periodontitis that included both clinical attachment level (CAL) and periodontal probing depth (PD) measurements. The association between alcohol consumption and chronic periodontitis was evaluated by multivariable regression analyses adjusting for age, gender, race/ethnicity, education level, income-to-poverty ratio, smoking, self-rated overall oral health, and HbA_1c .

RESULTS

The odds ratio (95% confidence interval) of having severe periodontitis was 1.9 (1.2-3) among participants who reported alcohol consumption of ≥8 drinks compared to participants consuming some alcohol but < 1 drink per week on average. Participants who consumed 1- < 8, and ≥8 drinks per week, on average, also had higher mean PD, percentage of sites with PD ≥4 mm, mean CAL, and percentage of sites with CAL ≥3 mm compared to participants reporting consumption of < 1 drink per week. Meanwhile, the odds of having periodontitis, mean PD, extent PD ≥4 mm, mean CAL, and extent CAL ≥3 mm were not significantly different for nondrinkers than for participants who consumed some alcohol but < 1 drink per week on average.

CONCLUSIONS

Alcohol consumption was associated with an increase in the likelihood of having periodontitis, particularly severe periodontitis. Consumption of some alcohol, < 1 drink per week on average, was associated with similar odds of having periodontitis compared to consumption of no alcohol.

Ethanol and its metabolites: update on toxicity, benefits, and focus on immunomodulatory effects

This article summarizes recent experimental and epidemiological data on the toxic and beneficial effects of ethanol and its metabolites (acetaldehyde), and focuses on their immunomodulatory effects. The section dealing with the toxic effects of alcohol focuses on its chronic toxicity (liver disorders, carcinogenic effects, cardiovascular disorders, neuropsychic disorders, addiction and withdrawal syndrome, hematologic disorders, reprotoxicity, osteoporosis) although acute toxicity is considered. The role of oxidative metabolism of ethanol by alcohol dehydrogenase, cytochrome P450 2E1, and aldehyde dehydrogenase, as well as the impact of genetic polymorphism in its physiopathology are also highlighted. The section dealing with the beneficial effects of low to moderate alcohol consumption (on cardiovascular system, diabetes, the nervous system and sensory organs, autoimmune diseases, and rheumatology) highlights the importance of anti-inflammatory and immunomodulatory effects in these observations. This knowledge, enriched by a focus on the immunomodulatory effects of ethanol and its metabolites, in particular on the NLRP3 inflammasome pathway, might facilitate the development of treatments that can reduce ethanol's harmful effects or accentuate its beneficial effects.

Changes in behaviors after diagnosis of type 2 diabetes and 10-year incidence of cardiovascular disease and mortality

Background

Large changes in health behaviors achieved through intensive lifestyle intervention programs improve cardiovascular disease (CVD) risk factors among adults with type 2 diabetes. However, such interventions are not widely available, and there is limited evidence as to whether changes in behaviors affect risk of CVD events.

Methods

Among 852 adults with screen-detected type 2 diabetes in the ADDITION-Cambridge study, we assessed changes in diet, physical activity, and alcohol use in the year following diabetes diagnosis. Participants were recruited from 49 general practices in Eastern England from 2002 to 2006, and were followed through 2014 for incidence of CVD events (n = 116) and all-cause mortality (n = 127). We used Cox proportional hazards regression to estimate hazard ratios (HR) for the associations of changes in behaviors with CVD and all-cause mortality. We estimated associations with CVD risk factors using linear regression. We considered changes in individual behaviors and overall number of healthy changes. Models adjusted for demographic factors, bodyweight, smoking, baseline value of the health behavior, and cardio-protective medication use.

Results

Decreasing alcohol intake by ≥ 2 units/week was associated with lower hazard of CVD vs maintenance [HR: 0.56, 95% CI 0.36, 0.87]. Decreasing daily calorie intake by ≥ 300 kcal was associated with lower hazard of all-cause mortality vs maintenance [HR: 0.56, 95% CI 0.34, 0.92]. Achieving ≥ 2 healthy behavior changes was associated with lower hazard of CVD vs no healthy changes [HR: 0.39, 95% CI 0.18, 0.82].

Conclusions

In the year following diabetes diagnosis, small reductions in alcohol use were associated with lower hazard of CVD and small reductions in calorie intake were associated with lower hazard of all-cause mortality in a population-based sample. Where insufficient resources exist for specialist-led interventions, achievement of moderate behavior change targets is possible outside of treatment programs and may reduce long-term risk of CVD complications.

Trends in the Incidence and Mortality of Diabetes in China from 1990 to 2017: A Joinpoint and Age-Period-Cohort Analysis

Background: The prevalence of diabetes mellitus is rapidly increasing in China, but the secular trends in incidence and mortality remain unknown. This study aims to examine time trends from 1990 to 2017 and the net age, period, and cohort effects on diabetes incidence and mortality. Methods: Incidence and mortality rates of diabetes (1990⁻2017) were collected for each 5-year age group (from 5⁻9 to 80⁻84 age group) stratified by gender from the Global Burden of Disease 2017 Study. The average annual percentage changes in incidence and mortality were analyzed by joinpoint regression analysis; the net age, period, and cohort effects on the incidence and mortality were estimated by age-period-cohort analysis. Results: The joinpoint regression analysis showed that age-standardized incidence significantly rose by 0.92% (95% CI: 0.6%, 1.3%) in men and 0.69% in women (95% CI: 0.3%, 1.0%) from 1990 to 2017; age-standardized mortality rates rose by 0.78% (95% CI: 0.6%, 1.0%) in men and decreased by 0.12% (95% CI: -0.4%, 0.1%) in women. For age-specific rates, incidence increased in most age groups, with exception of 30⁻34, 60⁻64, 65⁻69 and 70⁻74 age groups in men and 25⁻29, 30⁻34, 35⁻39 and 70⁻74 age groups in women; mortality in men decreased in the younger age groups (from 20⁻24 to 45⁻49 age group) while increased in the older age groups (from 50⁻54 to 80⁻84 age group), and mortality in women decreased for all age groups with exception of the age group 75⁻79 and 80⁻84. The age effect on incidence showed no obvious changes with advancing age while mortality significantly increased with advancing age; period effect showed that both incidence and mortality increased with advancing time period while the period trend on incidence began to decrease since 2007; cohort effect on incidence and mortality decreased from earlier birth cohorts to more recent birth cohorts while incidence showed no material changes from 1982⁻1986 to 2012⁻2016 birth cohort. Conclusions: Mortality decreased in younger age groups but increased in older age groups. Incidence increased in most age groups. The net age or period effect showed an unfavorable trend while the net cohort effect presented a favorable trend. Aging likely drives a continued increase in the mortality of diabetes. Timely population-level interventions aiming for obesity prevention, healthy diet and regular physical activity should be conducted, especially for men and earlier birth cohorts at high risk of diabetes.

Alcohol Intake and Weight Loss During Intensive Lifestyle Intervention for Adults with Overweight or Obesity and Diabetes

OBJECTIVE

This study aimed to assess whether alcohol consumption decreases during an intensive lifestyle intervention (ILI) and whether alcohol consumption is associated with weight loss among participants with overweight or obesity and type 2 diabetes.

METHODS

Participants (n = 4,901) were from the Action for Health in Diabetes (Look AHEAD) study, a randomized controlled trial that compared an ILI with a diabetes support and education (DSE) control. Mixed-effects models were used to estimate the effect of the ILI on alcohol consumption and the influence of alcohol consumption on weight loss at year 4.

RESULTS

ILI and DSE participants did not differ in changes in alcohol consumption. Alcohol intake was not associated with weight loss at year 1 of the ILI. ILI participants who abstained from alcohol lost 5.1% ± 0.3% of initial weight at year 4 compared with a significantly (P = 0.04) smaller 2.4% ± 1.3% for consistent heavy drinkers. ILI participants who abstained from alcohol consumption over the 4 years lost 1.6% ± 0.5% more weight relative to individuals who drank alcohol at any time during the intervention (P = 0.003). DSE participants did not differ in weight loss by alcohol consumption.

CONCLUSIONS

Heavy alcohol drinkers are at risk for suboptimal long-term weight loss. Decreasing alcohol consumption may improve weight management among individuals with diabetes.

Metabolic syndrome is a risk factor for cancer mortality in the general Japanese population: the Jichi Medical School Cohort Study

BACKGROUND

Metabolic syndrome (MetS) and cancer are major public health problems worldwide. The relationship between MetS and cancer death is of great interest. We examined the predictive value of MetS for cancer mortality in Japan.

METHODS

Study participants included 4495 men and 7028 women aged 18-90 years who were registered between 1992 and 1995 as part of the Jichi Medical School Cohort Study. We used a definition of MetS modified for the Japanese population. The primary outcome was cancer mortality. Additionally, the relationship between MetS and cancer-type specific mortality was examined. Analyses were conducted with Cox's regression models adjusted for age, smoking status, alcohol drinking status, marital status, educational attainment, physical activity, occupational category, and menopausal status (only in women).

RESULTS

During a mean follow-up of 18.5 years, 473 men and 297 women died from cancer. MetS was positively associated with cancer mortality in women (hazard ratio [HR], 1.69; 95% confidence interval [CI] 1.21-2.36), but not in men (HR, 1.21; 95% CI 0.90-1.62). Additionally, MetS was associated with a high risk of colorectal (HR, 3.48; 95% CI 1.68-7.22) and breast (HR, 11.90; 95% CI 2.25-62.84) cancer deaths in women.

CONCLUSION

MetS was a significant predictor of cancer mortality in women.

Lifetime Alcohol Use Patterns and Risk of Diabetes Onset in the National Alcohol Survey

BACKGROUND

Studies of the role of alcohol use in diabetes risk have rarely included lifetime alcohol use measures, including the frequency of heavy occasions, or evaluated risks among Black or Hispanic respondents in US samples.

METHODS

Data from the 2014 to 2015 National Alcohol Survey of the U.S. population were used to estimate diabetes risk from drinking patterns at the time of onset in Cox proportional hazards models in a retrospective cohort design. Models for the population, males and females, and for White, Black, and Hispanic respondents of both genders were estimated using 2 versions of drinking pattern groupings at each age.

RESULTS

While a number of significant results were found with the first version of the drinking measures, we focus on those confirmed with measures from responses strictly prior to the age of risk estimation. Compared to the lifetime abstainer group, the "drinking at least weekly with less than monthly 5+" group had a significantly lower hazard ratio (HR) for the total sample (HR = 0.64) and among Whites (HR = 0.42). Significantly reduced risks were found in the same models for those who drank 5+ at least monthly but not weekly. No significantly elevated risks were found for either current or prior heavy occasion drinking.

CONCLUSIONS

These results are consistent with some prior studies in finding reduced risks for regular light-to-moderate drinkers, but not consistent with findings from other studies showing increased risk from heavy occasion drinking, particularly among women. New and larger studies with well-defined drinking pattern measures are needed, particularly for U.S. Blacks and Hispanics, to address varying results in this literature.

Inverse association of light-to-moderate alcohol drinking with cardiometabolic index in men with diabetes mellitus

AIMS

Cardiometabolic index (CMI), calculated as the product of waist-to-height ratio and triglycerides-to-HDL cholesterol ratio, has been proposed as a discriminator of diabetes and has been reported to be associated with progression of atherosclerosis. The purpose of this study was to determine the relationship between alcohol drinking and CMI in men with diabetes.

METHODS

The subjects were Japanese male workers aged from 35 to 65 years with diabetes mellitus (n = 1411). The subjects were divided by average daily alcohol consumption (g ethanol/day) into 4 categories of alcohol drinking (nondrinkers; light drinkers, < 22; moderate drinkers, ≥ 22 and < 44; heavy drinkers, ≥ 44). CMI and variables comprising CMI were compared in the nondrinker and each of the drinker groups. Age, habits of smoking and regular exercise, and a present history of medication therapy for diabetes were adjusted in each analysis.

RESULTS

Log-transformed CMI was significantly lower in light and moderate drinkers than in nondrinkers. Waist-to-height ratio was significantly lower in moderate drinkers than in nondrinkers, while log-transformed triglycerides was significantly higher in heavy drinkers than in nondrinkers. HDL cholesterol tended to be higher with an increase of alcohol consumption. Odds ratios with their 95% confidence intervals vs. nondrinkers for high CMI were 0.53 (0.36-0.78) in light drinkers, 0.61 (0.46-0.80) in moderate drinkers, and 0.74 (0.55-1.00) in heavy drinkers.

CONCLUSIONS

In men with diabetes, CMI is lower in light-to-moderate drinkers than in nondrinkers, and this results mainly from a positive association between alcohol drinking and HDL cholesterol.
