Purpose: Alcohol consumption is an established breast cancer risk factor, though further research is needed to advance our understanding of the mechanism underlying the association. We used global metabolomics profiling to identify serum metabolites and metabolic pathways that could potentially mediate the alcohol-breast cancer association.
Methods: A cross-sectional analysis of reported alcohol consumption and serum metabolite concentrations was conducted among 211 healthy women 25-29 years old who participated in the Dietary Intervention Study in Children 2006 Follow-Up Study (DISC06). Alcohol-metabolite associations were evaluated using multivariable linear mixed-effects regression.
Results: Alcohol was significantly (FDR p < 0.05) associated with several serum metabolites after adjustment for diet composition and other potential confounders. The amino acid sarcosine, the omega-3 fatty acid eicosapentaenoate, and the steroid 4-androsten-3beta,17beta-diol monosulfate were positively associated with alcohol intake, while the gamma-tocopherol metabolite gamma-carboxyethyl hydroxychroman (CEHC) was inversely associated. Positive associations of alcohol with 2-methylcitrate and 4-androsten-3beta,17beta-diol disulfate were borderline significant (FDR p < 0.10). Metabolite set enrichment analysis identified steroids and the glycine pathway as having more members associated with alcohol consumption than expected by chance.
Conclusions: Most of the metabolites associated with alcohol in the current analysis participate in pathways hypothesized to mediate the alcohol-breast cancer association including hormonal, one-carbon metabolism, and oxidative stress pathways, but they could also affect risk via alternative pathways. Independent replication of alcohol-metabolite associations and prospective evaluation of confirmed associations with breast cancer risk are needed.

Introduction: Optimal control of cardiovascular risk factors remains challenging in non-classical patient groups, including those with metabolic dysfunction-associated steatotic liver disease (MASLD). Dietary restrictions are among the interventions that may be helpful in such cases.
Aim: To evaluate if the declared type of fasting influences the most common cardiovascular risk factor control in patients with MASLD.

Background: Alcohol dependence remains a significant global health issue, exacerbated by the coronavirus disease 2019 (COVID-19) pandemic. Phosphatidylethanol (PEth), a direct biomarker of recent alcohol consumption, offers improved specificity, sensitivity, and a longer detection window of 2 - 4 weeks compared to traditional biomarkers. This study evaluates the association between PEth testing and hospital outcomes in hospitalized patients by comparing outcomes among patients with positive PEth and negative PEth test results.

Background: The strong association between type 2 diabetes mellitus (T2DM) and fatty liver is well known, and its nomenclature has even recently changed to metabolic dysfunction-associated steatotic liver disease (MASLD). Healthy MASLD patients are frequently overlooked and maltreated, especially in Bangladesh. In this present study, we tried to correlate T2DM burden in apparently healthy, incidentally diagnosed fatty liver patients on ultrasound.

Introduction: Excessive alcohol use is a major public health concern, for which internet interventions have shown to be effective. Group-average effects may however mask substantial inter-individual variations in changes; identifying predictors of this variation remains an important research question. Biological sex is associated with pharmacokinetic differences in alcohol tolerance, which is reflected in many national guidelines recommending sex-specific thresholds for excessive drinking.

Methods: An RCT of CBT-I (n = 31) compared to Quasi-Desensitization therapy (QDT, n = 32), eight weekly in-person sessions, with assessments at baseline, end of treatment (8 weeks), and 3- and 6-months post-treatment. Primary outcomes were the Insomnia Severity Index (ISI) total score, and Percent Days Abstinent (PDA).
