The association of steatotic liver disease with recurrent ischemic events in patients with chronic coronary syndrome: a multicenter cohort study

Abstract Background/introduction A panel of multi-society experts has proposed new subcategories under the term steatotic liver disease (SLD), replacing the exclusive term non-alcoholic fatty liver disease with the new nomenclature metabolic dysfunction-associated steatotic liver disease (MASLD). However, the prognostic impact of SLD subtypes in patients with chronic coronary syndrome (CCS) remains unknown. Purpose We aimed to investigate the associations between SLD subtypes and recurrent event risks in CCS patients. Methods Our analysis included a total of 9,448 patients with CCS from a large multicenter nationwide cohort. Hepatic steatosis was defined as hepatic steatosis index ≥36 and ultrasound evidence. Patients were categorized into four groups based on the evidence of steatosis, cardiometabolic risk factors and alcohol intake: 1) no SLD; 2) MASLD; 3) MASLD with increased alcohol intake (MetALD) and 4) SLD with other causes. The primary outcome was major adverse cardiac and cerebrovascular events (MACCE), a composite of all-cause mortality, myocardial infarction, stroke and unplanned revascularization. Results The prevalence of no SLD, MASLD, MetALD and SLD with other causes in our population was 37.3%, 47.7%, 14.7% and 0.3%, respectively. During a median follow-up of 2.0 years, 759 (8.0%) MACCE events occurred. After multivariable adjustment, MASLD (HR 1.25, 95%CI 1.06-1.48), MetALD (HR 1.31, 95%CI 1.04-1.65) and SLD with other causes (HR 2.81, 95%CI 1.04-7.57) were all significantly associated with higher MACCE risks compared to no SLD. Conclusions A significant proportion of SLD was observed in CCS patients. Patients with various SLD subcategories all had higher risks of recurrent events.

Alcohol intake and patterns of multi-site musculoskeletal pain in the British Whitehall II study

Abstract Background Patterns of multi-site musculoskeletal (MSK) pain and its relationship with alcohol drinking among white-collar employees and retirees remain unclear compared to blue-collar workers. This study aimed to examine the relationship between alcohol drinking and MSK pain through latent class analysis (LCA) in current and retired white-collar employees. Methods We used the data from the 7th phase (2000-2002, n = 6,967, response rate 71.6%) of the British Whitehall II study, chosen for its availability of MSK items and approximately 1:1 ratio of employees to retirees, allowing for an evaluation of the relationship between alcohol drinking and MSK pain by employment status. LCA was used to distinguish patterns of multi-site MSK pain. A multinomial logistic regression model was used to examine the association between alcohol drinking and the identified pain patterns, with analyses conducted separately for employees and retirees. Results We identified five latent classes for pain (back/cervical: 7.1%, cervical: 28.9%, upper limb: 29.4%, combined LBP/upper limb/cervical: 13.2%, and LBP alone: 21.5%). Increased alcohol intake might be associated with elevated odds of upper limb pain in current drinkers, but this could not be statistically confirmed (OR: 1.04, 95% CI: 0.99-1.09). Employment status may modify the association with a significant interaction found between alcohol intake and retirement (p-value: 0.043). Every 7-unit increase in alcohol intake is associated with 18% and 12% higher odds of pain in LBP/UBP/cervical and upper limbs, respectively (95% CI: 1.02-1.37; 1.02-1.23). Conclusions Increased alcohol intake was associated with pain patterns only among retired white-collar employees but not the current ones. Interventions on alcohol consumption could help confirm if, reducing alcohol intake or avoiding hazardous drinking, for white-collar retirees prevents not only upper limb pain but also more complex pain patterns. Key messages • Musculoskeletal pain in white-collar employees and retirees contributes to the cervical and upper extremities, differing from low back/neck pain studies among general or blue-collar workers. • The association between alcohol drinking and pain patterns may differ across employment status. Reducing alcohol intake might be advised to retired drinkers for preventing multi-site pain.

Differential effects of chronic and intermittent administration of taurine on alcohol binge drinking in male rats

Episodic consumption of high doses of alcohol in a short period (binge drinking - BD) among adolescents is known to be harmful to their brain development. Chronic use of taurine increases voluntary alcohol consumption and shows an anxiolytic-like effect in rats. In this study, we evaluated the differential effects of chronic and intermittent taurine administration on alcohol consumption and behavioral changes in adolescent and young adult rats subjected to the BD model. Male Wistar rats (35 days old) were divided into 4 groups for daily intraperitoneal administration of saline (SAL); taurine, 100 mg/kg (TAU); taurine on BD days and saline on intervals (TAU/SAL); and saline on BD days and taurine on intervals (SAL/TAU). They were exposed to 4 cycles of BD, with free access to alcoholic solution (20 % w/v), for 2 h, 3 days per week. At the end of the 3rd cycle, anxiety-like behaviors were assessed using the light-dark task. After euthanasia, plasma and prefrontal cortex samples were collected to measure corticosterone and BDNF levels, respectively. Chronic taurine treatment did not alter alcohol consumption in rats, whereas intermittent administration increased alcohol intake after 4 BD exposures (TAU/SAL: +19.4 % and SAL/TAU: +21.6 %). No anxiolytic-like effects were found by taurine administration, nor were there changes in serum corticosterone or BDNF levels in the frontal cortex of young adult rats. Intermittent taurine, but not chronic treatment, increased alcohol intake among rats after the second week of exposure. The translation of these results to humans is concerning since the combination of alcohol and drinks containing taurine is common among adolescent and young adult individuals.

Increasing rates of early-onset Luminal A breast cancers correlate with binge drinking patterns

BackgroundBreast cancer (BC) rates have been increasing in young women in the U.S. Alcohol is an established risk factor for breast cancer and has been consistently associated with hormone receptor positive cancers, the type of breast cancer that has been increasing the fastest in young women. Given these trends, we conducted an ecological study to examine whether alcohol consumption, and specifically binge drinking trends, were correlated with female breast cancer diagnosed under 40 years of age using breast cancer data from the Surveillance, Epidemiology, and End Results (SEER) Cancer Registry. We accounted for a latent period before cancer diagnosis by using exposure 10 years before the outcome (lag model); we also conducted a separate cumulative analysis of 10-year aggregate exposure.FindingsModerate (Incidence Rate Ratio (IRR) = 1.05, 95% Confidence Interval (CI) = 1.02–1.07) and heavy (IRR = 1.05, 95% CI = 1.02–1.07)(≥ 1 and ≥ 2 drinks/day, respectively) alcohol consumption were each associated with Luminal A breast cancer but not the other molecular subtypes. Binge drinking was associated with an increased rate of early-onset Luminal A BC in both the 10-year lag model (IRR = 1.06, 95% CI = 1.02 to 1.11) and the cumulative model (IRR = 1.05, 95% CI = 1.02–1.07). Binge drinking was also associated with early-onset Luminal B BC in the cumulative model (IRR = 1.04, 95% CI = 1.01–1.07), but not associated with ERBB2-enriched or triple negative early-onset BC in either model.ConclusionThese trends support the hypothesis that one reason for the increase in early-onset breast cancer is from increased alcohol intake including binge drinking.

Acute Alcohol Consumption and Arrhythmias in Young Adults: The MunichBREW II Study.

and aims: Acute excessive alcohol intake may cause the holiday heart syndrome, characterized by cardiac arrhythmias including atrial fibrillation. Since underlying data are scarce, the study aimed to prospectively investigate the temporal course of occurring cardiac arrhythmias following binge drinking in young adults. A total of 202 volunteers planning acute alcohol consumption with expected peak breath alcohol concentrations (BAC) of ≥1.2 g/kg were enrolled. The study comprised 48-hour electrocardiogram (ECG) monitoring covering baseline (hour 0), 'drinking period' (hours 1-5), 'recovery period' (hours 6-19), and two control periods corresponding to 24 hours after the 'drinking' and 'recovery periods', respectively. Acute alcohol intake was monitored by BAC measurements during the 'drinking period'. ECGs were analyzed for mean heart rate, atrial tachycardia, premature atrial complexes (PAC), premature ventricular complexes (PVC), and heart rate variability (HRV) measures. Data revealed an increase in heart rate and an excess of atrial tachycardias with increasing alcohol intake. HRV analysis indicated an autonomic modulation with sympathetic activation during alcohol consumption and the subsequent 'recovery period', followed by parasympathetic predominance thereafter. PACs occurred significantly more frequently in the 'control periods', whereas PVCs were more frequent in the 'drinking period'. Ten participants experienced notable arrhythmic episodes, including atrial fibrillation and ventricular tachycardias, primarily during the 'recovery period'. The study demonstrates the impact of binge drinking on heart rate alterations and increased atrial tachycardias during 'drinking period', and the occurrence of clinically relevant arrythmias during the 'recovery period', emphasizing the holiday heart syndrome as a health concern.

Metabolic dysfunction‐associated steatotic liver disease and MetALD increases the risk of liver cancer and gastrointestinal cancer: A nationwide cohort study

SummaryBackgroundThe new nomenclature of metabolic dysfunction‐associated steatotic liver disease (MASLD) substituting nonalcoholic fatty liver disease was proposed along with a new category of MASLD with increased alcohol intake (MetALD).AimsWe aimed to explore the cancer risk by MASLD and MetALD.MethodsThis nationwide cohort study included 3,596,709 participants who underwent a health check‐up in 2011 in South Korea. Steatotic liver disease (SLD) was defined as a fatty liver index ≥30. Participants were categorized into four exclusive groups: MASLD, MetALD, other combination aetiology and no SLD. The subdistribution hazard ratio (SHR) was calculated using the Fine–Gray model after adjusting other variables.ResultsDuring the 33.9 million person‐years of follow‐up, 285,845 participants (7.9%) developed cancers. Compared with no SLD, MASLD, MetALD and other combination aetiology had an increased risk of all cancer. Liver cancer risk escalated from no SLD to MASLD (SHR, 1.16; 95% CI, 1.12–1.21), MetALD (SHR, 2.06; 95% CI, 1.92–2.20) and other combination aetiology (SHR, 8.16; 95% CI, 7.69–8.67). Gastrointestinal cancers including oesophagus, stomach, colorectal, biliary and pancreas cancers increased in MASLD (SHR, 1.13; 95% CI, 1.11–1.15), MetALD (SHR, 1.17; 95% CI, 1.14–1.21) and other combination aetiology (SHR, 1.09; 95% CI, 1.05–1.13). A modest increase in lung cancer and hormone‐sensitive cancer was observed with MASLD.ConclusionsThis study showed that MASLD and MetALD are associated with an increased risk of cancer, particularly liver and gastrointestinal cancers. The findings build new evidence for the clinical outcomes of MetALD while highlighting the importance of managing alcohol intake properly in MASLD and MetALD.

Spleen stiffness measurement by vibration-controlled transient elastography at 100 Hz for non-invasive predicted diagnosis of clinically significant portal hypertension in patients with compensated advanced chronic liver disease: a modelling study

In patients with compensated advanced chronic liver disease (cACLD), risk of clinically significant portal hypertension (CSPH) can be estimated by applying non-invasive tests such as liver stiffness measurement (LSM), platelet count, and, in some cases, BMI. We aimed to assess the diagnostic utility of spleen stiffness measurement (SSM) at 100 Hz as a standalone non-invasive test for CSPH and to evaluate its incremental value compared with the ANTICIPATE±NASH model in patients with cACLD. For this modelling study, patients were recruited from 16 expert centres in Europe. Patients who underwent characterisation by hepatic venous pressure gradient (HVPG) and non-invasive tests (ie, LSM, platelet count, and SSM at 100 Hz) at one of the participating centres between Jan 1, 2020, and Dec 31, 2023, were considered for inclusion. Only patients aged 18 years or older with Child-Pugh class A cACLD, shown by LSM 10 kPa or more or F3 or F4 fibrosis on liver histology, were included. The overall cohort was split into the derivation cohort (patients recruited between Jan 1, 2020, and Dec 31, 2022) and the temporal validation cohort (patients recruited between Jan 1, 2023, and Dec 31, 2023). The ANTICIPATE±NASH model was applied to assess individual CSPH probability and SSM was investigated as a standalone non-invasive test for CPSH; in combination with platelet count and BMI; and in a full model of SSM, LSM, platelet count, and BMI (ie, the Non-Invasive CSPH Estimated Risk [NICER] model). All models were binary logistic regression models. The primary outcome was CSPH. We evaluated the discriminative utility of the models by calculating the area under the receiver operating characteristics curve (AUC) and creating calibration plots and calibration of intercept, slope, and integrated calibration index. 407 patients with cACLD were included, 202 (50%) in the derivation cohort and 205 (50%) in the validation cohort. Median age was 60·0 years (IQR 55·0-66·8); 275 (68%) of 407 patients were male and 132 (32%) were female. 164 (40%) of 407 patients had metabolic dysfunction-associated steatotic liver disease (MASLD), 133 (33%) had MASLD with increased alcohol intake or alcohol-related liver disease, 75 (18%) had viral hepatitis (61 [81%] of whom had sustained virologic response of hepatitis C virus or suppression of hepatitis B virus DNA), and 35 (9%) had other chronic liver diseases. 241 (59%) patients had CSPH. Median SSM was 45·0 kPa (32·1-65·4) and LSM was 21·4 kPa (14·1-31·6). SSM and LSM had similar AUCs for prediction of CSPH in the derivation cohort (0·779 [95% CI 0·717-0·842] vs 0·781 [0·718-0·844]; p=0·97) and in the validation cohort (0·830 [0·772-0·887] vs 0·804 [0·743-0·864]; p=0·50). The SSM-based model comprising platelet count and BMI had a similar AUC as the ANTICIPATE±NASH model in both the derivation cohort (0·849 [0·794-0·903] vs 0·849 [0·794-0·903]; p=0·999) and in the validation cohort (0·873 [0·819-0·922] vs 0·863 [0·810-0·916]; p=0·75). The NICER model had a significantly higher AUC for prediction of CSPH than the ANTICIPATE±NASH model in the derivation cohort (0·889 [0·843-0·934] vs 0·849 [0·794-0·903]; p=0·022) and in the validation cohort (0·906 [0·864-0·946] vs 0·863 [0·810-0·916]; p=0·012). The addition of SSM to LSM, BMI, and platelet count outperformed the ANTICIPATE±NASH model for CSPH risk stratification in our cohort of contemporary patients with cACLD. SSM improves the non-invasive diagnosis of CSPH, supporting its implementation into clinical practice. Echosens.

Metabolic dysfunction-associated steatotic liver disease (MASLD) with increased alcohol intake (MetALD): a nonsensical concept and unwanted confusion

Metabolic dysfunction-associated steatotic liver disease (MASLD) with increased alcohol intake (MetALD): a nonsensical concept and unwanted confusion

Metabolic bariatric surgery, alcohol misuse and liver cirrhosis: a narrative review

Bariatric surgery and liver cirrhosis have considerable overlap. Bariatric procedures intend to reduce metabolic dysfunction-associated steatotic liver disease (MASLD); however, these procedures are thought to increase the propensity for alcohol misuse. This may predispose the bariatric surgical patient to a new form of liver insult in the postoperative period. This review explores the complex relationship between obesity and alcohol misuse in the context of the bariatric surgical patient. There is evidence to support the safety of bariatric procedures in compensated cirrhotic patients, with an improvement of liver function and architecture. However, data suggest that after a two-year period, these patients exhibit an increased propensity for alcohol misuse postoperatively, particularly after sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) procedures. A paucity of evidence exists with respect to alcohol-induced liver dysfunction, or MASLD and increased alcohol intake (MetALD) in the post-bariatric surgery patient. This review aims to provide an overview of the current evidence and offer recommendations for further robust studies.

Mortality outcomes in individuals with MASLD versus MASLD and increased alcohol intake.

Metabolic dysfunction-associated steatotic liver disease (MASLD) has become a leading cause of chronic liver disease worldwide. A new entity termed MetALD has also been described and is defined as individuals with MASLD and increased alcohol intake. However, the natural history of MetALD compared with MASLD is unknown. We aimed to compare longitudinal outcomes in patients with MASLD versus MetALD. This study was performed using data from the National Health and Nutrition Examination Survey from 2011 to 2018. MASLD patients (defined by the United States Fatty Liver Index >30) who met cardiometabolic criteria including body mass index (BMI) >25 (BMI>23 in Asians), hypertension, diabetes mellitus, dyslipidemia, and hypertriglyceridemia were included. MetALD was defined as MASLD with increased alcohol intake (3-6 standard drinks per day in males; 2-5 standard drinks per day in females). A comparison of overall, cardiovascular, cancer-related, and other causes of mortality in patients with MASLD versus MetALD was performed. A total of 2838 individuals with MASLD and 2557 individuals with MetALD were included with a median follow-up time of 56months. MetALD patients were at increased risk of cancer-related mortality compared with patients with MASLD (hazard ratio 1.32; 95% confidence interval 1.14-1.53; P<0.01). However, there was no significant difference in overall, cardiovascular, and other causes of mortality. Patients with MetALD were at higher risk for cancer-related mortality than MASLD. Close attention to regular cancer surveillance and accurate classification of alcohol consumption in individuals with diagnosed MASLD is warranted to help improve patient care and outcome.

Metabolic dysfunction-associated steatotic liver disease (SLD) and alcohol-associated liver disease, but not SLD without metabolic dysfunction, are independently associated with new onset of chronic kidney disease during a 10-year follow-up period.

The new nomenclature of steatotic liver disease (SLD) including metabolic dysfunction-associated SLD (MASLD), MASLD and increased alcohol intake (MetALD), and alcohol-associated liver disease (ALD) has recently been proposed. We aimed to elucidate the relationship between each category of SLD and chronic kidney disease (CKD). We investigated the effects of various SLDs on the development of CKD, defined as estimated glomerular filtration rate (eGFR)<60mL/min/1.73m2 or positive for urinary protein, during a 10-year period in 12138 Japanese subjects (men/women, 7984/4154; mean age, 48years) who received annual health examinations including abdominal ultrasonography. The prevalences of SLD without metabolic dysfunction (SLD-MD[-]), MASLD, MetALD, and ALD were 1.7%, 26.3%, 4.9%, and 1.9%, respectively. During the follow-up period, 1963 subjects (16.2%) (men/women, 1374 [17.2%]/589 [14.2%]) had new onset of CKD. Multivariable Cox proportional hazard model analyses after adjustment of age, sex, eGFR, current smoking habit, diabetes mellitus, hypertension, and dyslipidemia showed that the hazard ratios (HR [95% confidence interval]) for the development of CKD in subjects with MASLD (1.20 [1.08-1.33], p=0.001) and those with ALD (1.41 [1.05-1.88], p=0.022), but not those with MetALD (1.11 [0.90-1.36], p=0.332), were significantly higher than the HR in subjects with non-SLD. Interestingly, subjects with SLD-MD[-] had a significantly lower HR (0.61 [0.39-0.96], p=0.034) than that in subjects with non-SLD. The addition of the novel classification of SLDs into traditional risk factors for the development of CKD significantly improved the discriminatory capacity. MASLD and ALD, but not SLD-MD[-], are independently associated with the development of CKD.

Alcoholic Liver Disease/Nonalcoholic Fatty Liver Disease Index for Classification of Patients with Steatotic Liver Disease.

Steatotic liver disease (SLD) encompasses metabolic dysfunction-associated steatotic liver disease (MASLD) and alcohol-associated liver disease (AALD) at extremes as well as an overlap group termed MASLD with increased alcohol intake (MetALD). The Alcoholic Liver Disease/Nonalcoholic Fatty Liver Disease Index (ANI) was proposed to differentiate ALD from nonalcoholic fatty liver disease (NAFLD). We analysed the performance of the ANI in differentiating within the SLD spectrum. In a cross-sectional study at a tertiary care center, 202 adults (>18 years) who were prospectively diagnosed with SLD defined by magnetic resonance imaging-proton density fat fraction >6.4% were enrolled. Alcohol consumption (AC) was recorded according to thresholds for significant AC: 140-350 g/week (or 20-50 g/day) for females and 210-420 g/week (or 30-60 g/day) for males. The ANI was calculated, and area under the receiver operating characteristic curve (AUROC) was generated. Of 202 patients (47 years [interquartile range, IQR, 38 to 55], 23.75% females, 77% obese, 42.1% with diabetes, 38.1% hypertensive, 28.7% statin use), 40.5% were ever-alcohol consumers; 120 (59%), 50 (24.7%), and 32 (15.8%) were MASLD (ANI, -3.7 [IQR, -7 to -1.6]; MetALD, - 1.45 [IQR, -2.4 to 0.28]; and AALD, 0.71 [IQR, -1.3 to 4.8], respectively; P<0.05 for all). The AUROC of the ANI for MASLD and AALD was 0.79 (IQR, 0.72 to 0.84; cut-off <-3.5) and 0.80 (IQR, 0.74 to 0.86; cut-off >-1.49), respectively. The ANI outperformed aspartate transaminase/alanine transaminase (AST/ALT) ratio (AUROC=0.75 [IQR, 0.69 to 0.81]) and gamma glutamyl transpeptidase (GGT) (AUROC=0.74 [IQR, 0.67 to 0.80]). Addition of GGT did not improve model performance (AUCdiff=0.004; P=0.33). AC is common in MASLD. The ANI distinguishes MASLD and AALD, with individual cut-offs within the intermediate zone indicating MetALD. ANI also outperforms AST/ALT ratio or GGT.

Impact of Physical Activity on Overall Survival and Liver Cirrhosis Incidence in Steatotic Liver Disease: Insights from a Large Cohort Study Using Inverse Probability of Treatment Weighting.

Physical activity is a cornerstone of a healthy lifestyle, with benefits in managing chronic diseases. This study investigates the relationship between physical activity and liver-related outcomes with or without steatotic liver diseases, including metabolic dysfunction-associated steatotic liver disease (MASLD) and MASLD and increased alcohol intake (MetALD). The primary outcomes of interest were overall survival in the entire population, individuals without steatotic liver disease, patients with MASLD, and those with MetALD. The secondary outcomes included the incidence of liver cirrhosis. Participants were categorized based on physical activity frequency and Kaplan-Meier survival curves and Cox proportional hazards models were used for analysis. Higher physical activity was associated with significantly better survival in the overall cohort and MASLD cohort before and after inverse probability of treatment weighting (IPTW). In participants without steatotic liver disease and the MetALD cohort, higher physical activity showed significant survival improvement after IPTW. For the incidence of liver cirrhosis, higher physical activity showed significant associations before IPTW in the overall cohort and MASLD cohort, but these associations were not significant after IPTW. Marginal significance was observed in the MetALD cohort before and after IPTW. In conclusion. promoting physical activity may be key in improving liver-related outcomes.

Clinical Characteristics of Steatotic Liver Disease Categories in a Large Cohort of Japanese Health Checkup Participants

Background and AimsThe clinical characteristics and risk factors involved in the development of liver fibrosis in the subtypes of steatotic liver disease (SLD) remain unknown. We examined the clinical characteristics of SLD subtypes using a large Japanese cohort. MethodsWe performed a cross-sectional analysis (total n=108,446). In this cohort, SLD was diagnosed by ultrasonography. Individuals with none of the cardiometabolic risk factors were excluded. ResultsAccording to their NAFLD and metabolic dysfunction-associated SLD (MASLD) status based on the database, participants with cardiometabolic criteria were allocated to the MASLD, MASLD with increased alcohol intake (MetALD), and alcohol-associated liver disease (ALD) with metabolic dysfunction groups. Of 30,857 subjects with SLD, 21,488 (69.6%) had nonalcoholic fatty liver disease (NAFLD), and 20,922 (67.8%) had MASLD. There were few differences in the clinical characteristics between NAFLD and MASLD. After adjustment for clinical variables, we found that male patients with MetALD [odds ratio (OR) 2.26; 95% confidence interval (CI) 1.87–2.84] and ALD with metabolic dysfunction (OR 3.92; 95% CI 2.85–5.39) had a significantly higher risk for advanced liver fibrosis (diagnosed by Fibrosis-4 (FIB-4) index >2.67) compared to those with MASLD. In female patients with ALD, metabolic dysfunction (OR 5.80; 95% CI 2.51–13.4) and systemic blood pressure of ≥130 mmHg were significant risk factors for high FIB-4 (males: OR 3.38, 95% CI 2.51–4.55; females: OR 4.34, 95% CI 2.66–7.07, P<0.001). ConclusionsAlcohol intake and systolic blood pressure are independent contributors to liver fibrosis progression assessed by FIB-4 in SLD.

A novel alcohol+nicotine co-use self-administration procedure reveals sex differences and differential alteration of mesocorticolimbic TLR- and cholinergic-related neuroimmune gene expression in rats

Although alcohol and nicotine are two of the most commonly co-used drugs with upwards of 90% of adults with an alcohol use disorder (AUD) in the US also smoking, we don't tend to study alcohol and nicotine use this way. The current studies sought to develop and assess a novel alcohol + nicotine co-access self-administration (SA) model in adult male and female Long-Evans rats. Further, both drugs are implicated in neuroimmune function, albeit in largely opposing ways. Chronic alcohol use increases neuroinflammation via toll-like receptors (TLRs) which in turn increases alcohol intake. By contrast, nicotine produces anti-inflammatory effects, in part, through the monomeric alpha7 receptor (ChRNa7). Following long-term co-access (6 months), rats reliably administered both drugs during daily sessions, however males generally responded for more alcohol and females for nicotine. This was reflected in plasma analysis with translationally relevant intake levels of both alcohol and nicotine, making it invaluable in studying the effects of co-use on behavior and CNS function. Moreover, male rats show sensitivity to alterations in alcohol concentration whereas females show sensitivity to alterations in nicotine concentration. Rats trained on this procedure also developed an anxiogenic phenotype. Finally, we assessed alterations in neuroimmune-related gene expression in the medial prefrontal cortex – prelimbic, (mPFC-PL), nucleus accumbens core (AcbC), and ventral tegmental area (VTA). In the AcbC, where α7 expression was increased and β2 was decreased, markers of pro-inflammatory activity were decreased, despite increases in TLR gene expression suggesting that co-use with nicotine modulates inflammatory state downstream from the receptor level. By contrast, in mPFC-PL where α7 was not increased, both TLRs and downstream proinflammatory markers were increased. Taken together, these findings support that there are brain regional and sex differences with co-use of alcohol + nicotine SA and suggest that targeting nicotinic α7 may represent a novel strategy for treating alcohol + nicotine co-dependence.

May Measurement Month 2021: an analysis of blood pressure screening results from Albania.

This article describes the May Measurement Month (MMM) 2021 campaign, which was the fourth time this annual hypertension screening campaign was conducted in Albania, a Mediterranean country in southeastern Europe. The MMM21 was conducted during the period of 28 September-30 November 2021, in 32 sites across several districts of Albania. Overall, 11 788 participants aged ≥18 years were included (63% women), with a mean age of 49.7 ± 14.9 years. Blood pressure (BP) was measured three times with Omron sphygmomanometers (model M3, Omron Healthcare, Kyoto, Japan), which are automatic upper arm BP monitors. Hypertension was defined as SBP ≥ 140 mmHg or diastolic blood pressure (DBP) ≥ 90 mmHg (based on the mean of the second and third recordings for SBP and DBP, respectively) or on antihypertensive medication. Self-reported data included pre-existing conditions, physical activity, smoking, alcohol consumption, COVID-19 testing, and use of contraception in women. Overall, 47.3% of screened participants had hypertension. Of those with hypertension, 70.1% were aware of their condition and 67.0% were on antihypertensive medication. About half (49.3%) of participants on antihypertensive medication had controlled BP (<140/90 mmHg). On average, BP was higher in those on antihypertensive medication and with increasing alcohol intake but lower in those with a history of stroke and those with higher levels of physical activity, previous positive COVID-19 test, and contraception use in women. In Albania, the MMM campaign continues to contribute to the early detection of hypertension among adults. Hence, it constitutes a valuable opportunistic screening instrument among other routine tools applied in the general Albanian population.

Low-to-moderate alcohol consumption is associated with increased fibrosis in individuals with metabolic dysfunction-associated steatotic liver disease

Both metabolic dysfunction and alcohol consumption cause steatotic liver disease (SLD). The distinction between metabolic dysfunction-associated SLD (MASLD) and MetALD categories is based on arbitrary thresholds of alcohol intake. Thus, we assessed the impact of different levels of alcohol consumption on SLD severity and their interaction with metabolic comorbidities. We performed a population-based study with transient elastography (FibroScan®) data from participants in Spain (derivation cohort) and the US (validation cohort). A controlled attenuation parameter ≥275dB/m was used to define SLD. At least one cardiometabolic risk factor was required to define MASLD. Among patients with MASLD, low alcohol consumption was defined as an average of 5-9 drinks/week, moderate consumption as 10-13 drinks/week for females and 10-20 drinks/week for males, and increased alcohol intake (MetALD) as 14-35 drinks/week for females and 21-42 drinks/week for males. Significant fibrosis was defined as a liver stiffness measurement ≥8kPa and at-risk metabolic dysfunction-associated steatohepatitis (MASH) as a FAST score ≥0.35. The derivation cohort included 2,227 individuals with MASLD (9% reported low, 14% moderate alcohol consumption) and 76 cases with MetALD. Overall prevalences of significant fibrosis and at-risk MASH were 7.6% and 14.8%, respectively. In the multivariable analysis, alcohol consumption was independently associated with significant fibrosis and at-risk MASH. A dose-dependent increase in the prevalence of significant fibrosis and at-risk MASH was observed between the number of drinks/week and the number of cardiometabolic factors. The validation cohort included 1,732 participants with MASLD, of whom 17% had significant fibrosis and 13% at-risk MASH. This cohort validated the association between moderate intake and MASLD at risk of progression (odds ratio 1.69, 95% CI 1.06-2.71). Moderate alcohol intake is commonly seen in MASLD and increases the risk of advanced disease to a level similar to that observed in MetALD. Metabolic risk factors such as overweight, diabetes or dyslipidemia, and alcohol consumption can cause liver disease. These factors frequently coexist, but their joint effects on liver fibrosis remain uncertain. In this study, we have analyzed individuals from the general population with MASLD (metabolic dysfunction-associated steatotic liver disease) enrolled in Spain and the US. We show that moderate alcohol consumption has a supra-additive effect with metabolic risk factors, exponentially increasing the risk of liver fibrosis. These results suggest that there are no safe limits of daily alcohol intake in patients with unhealthy metabolic status and MASLD.

Liver Cancer Risk Across Metabolic Dysfunction-Associated Steatotic Liver Disease and/or Alcohol: A Nationwide Study.

New terminologies of metabolic dysfunction-associated steatotic liver disease (MASLD) have been developed. We assessed hepatocellular carcinoma (HCC) risk across MASLD and/or alcohol intake. We included participants aged 40-79 years receiving a national health checkup from 2009 to 2010 in the Republic of Korea, classified as follows: non-MASLD, MASLD, MASLD with increased alcohol intake (MetALD; weekly alcohol 210-420 g for male and 140-350 g for female individuals), and alcohol-associated liver disease (ALD; excessive alcohol intake with weekly alcohol ≥420 g for male or ≥350 g for female individuals). The primary outcome was HCC incidence. HCC risk was estimated using multivariable Cox proportional hazard models. Among 6,412,209 participants, proportions of non-MASLD, MASLD, MetALD, and ALD cases were 59.5%, 32.4%, 4.8%, and 3.4%, respectively. During follow-up (median 13.3 years), 27,118 had newly developed HCC. Compared with non-MASLD, the HCC risk increased from MASLD (adjusted hazard ratio [aHR] 1.66, 95% confidence interval [CI] 1.62-1.71) and MetALD (aHR 2.17, 95% CI 2.08-2.27) to ALD (aHR 2.34, 95% CI 2.24-2.45) in a stepwise manner. Furthermore, the older and non-cirrhosis subgroups were more vulnerable to detrimental effects of MASLD and/or alcohol intake, concerning HCC risk. Among the older, female, and cirrhosis subgroups, MetALD poses similar HCC risks as ALD. HCC risk increased from MASLD and MetALD to ALD in a stepwise manner, compared with non-MASLD. For an effective primary prevention of HCC, a comprehensive approach should be required to modify both metabolic dysfunction and alcohol intake habit.

Reassessing the Impact of Coffee Consumption on Liver Disease: Insights from a Large-Scale Cohort Study with IPTW Adjustment.

Coffee consumption is globally widespread and has become a lifestyle habit. This study investigated coffee consumption and liver-related survival in a large cohort of 455,870 individuals with UK biobank, categorized into without steatosis, metabolic dysfunction-associated steatotic liver disease (MASLD), and MASLD and increased alcohol intake (MetALD). Inverse probability of treatment weighting (IPTW) adjusted for confounding variables was used, followed by Kaplan-Meier analysis. Moderate coffee consumption (1-2 cups per day) was associated with lower all-cause mortality across the entire cohort, without the steatosis, MASLD (p < 0.0001), and MetALD cohorts (p = 0.0047 for pre-IPTW, p = 0.027 for post-IPTW). Before IPTW adjustment, consuming one or more cups of coffee per day appeared to significantly reduce liver-related mortality in the overall (p = 0.015) and MASLD cohorts (p = 0.011). However, post-IPTW application, no significant differences in liver-related mortality were observed between the coffee intake groups (p = 0.778, 0.319, 0.564, 0.238 for each group). While increased coffee consumption initially seemed to reduce liver-related mortality, after IPTW adjustment, only all-cause mortality significantly decreased (p < 0.0001 and p = 0.027). These findings suggest that previous studies might have overestimated the favorable effect of coffee intake on chronic liver disease due to confounding factors.

Impact of Alcohol Consumption upon Ischemic Heart Disease: Comparative Study

Objective: the aim of the study is to evaluate the effectiveness of alcohol consumption on the ischemic heart disease Methodology: An descriptive design was used to carried out this study in medical ward at Ibn Al-Biter Specialized Center for Cardiac Surgery for the period from October 2022 to April 2023. The size of sample was 50 Ischemic Heart Disease patients divided into two groups each one consisted of 25 patients as control group and study group. The study group was drinking alcohol while the control group was not drinking alcohol. The study instrument consisted from four parts, socio – demographic data; Clinical Characteristics data; Assessment of Alcohol Drinking forma and Assessment for IHD was performed by Echo cardiograph Results: The results of the study presented left ventricular function scores for the none drinking group remained essentially the abnormal less than normal while the left ventricular function scores for the drinking group remained essentially the normal less than abnormal Conclusion: Increasing alcohol intake is associated with subtle alterations in cardiac structure and function Recommendations: more research is needed to better understand the effects of alcohol consumption on the CV systems of older populations.
