Objective: The purpose of this study is to determine the accuracy of retrospective estimated blood alcohol concentrations (eBACs) for re-creating intoxication resulting from a naturally occurring drinking event. This study identified five eBAC equations, applied them to self-report data and compared the results to actual blood alcohol concentration obtained by a breath test.
Method: A convenience sample of 109 drinkers was recruited near drinking establishments and asked to provide breath alcohol concentration (BrAC) samples. Participants were contacted by telephone on the next waking day to gather data required for five algorithms that determine eBAC. BrAC and eBAC obtained from each equation were compared to determine the level of agreement between the two approaches.
Results: eBACs correlated highly with each other (r > or = 0.99); R2 for all algorithms ranged from 0.54 to 0.55 with BrAC as the criterion. On average, eBAC equations overestimated BrAC. Regression analysis identified the amount of time spent drinking, number of standard drinks, weight and year in school as factors related to discrepancy.
Conclusions: These data indicate that, although all equations produce eBACs that are highly related, their relationship to BrAC does vary across equations. Using the best fitting equation, eBAC is more strongly correlated with BrAC when intoxication is less than 0.08 g/210 L of breath, and the magnitude of the relationship decreases as intoxication rises.

Chronic kidney disease (CKD) is a global health challenge associated with lifestyle factors such as diet, alcohol, BMI, smoking, sleep, and physical activity. Metabolomics, especially nuclear magnetic resonance(NMR), offers insights into metabolic profiles' role in diseases, but more research is needed on its connection to CKD and lifestyle factors. Therefore, we utilized the latest metabolomics data from the UK Biobank to explore the relationship between plasma metabolites and lifestyle factors, as well as to investigate the associations between various factors, including lifestyle-related metabolites, and the latent phase of CKD onset.

Bacterial-infected wounds usually lead to slow wound healing due to increased inflammation, especially wounds infected by drug-resistant bacteria, which is a serious challenge in the biomedical field. Traditional antimicrobial strategies such as antibiotics lead to a significant increase in drug-resistant strains and have limited efficacy. Therefore, there is an urgent need to develop multifunctional dressings with excellent antibacterial activity and promotion of wound healing.

Background: Contingency management (CM) is an intervention for alcohol use disorder (AUD) that reinforces abstinence, as confirmed by alcohol biomarkers. CM is usually brief (12-16 weeks) despite evidence that longer interventions have better long-term outcomes. Most CM models are in-person which can also be a barrier for treatment.

Background: Non-communicable diseases (NCDs) are governed by a cluster of unhealthy behaviours and their determinants, like tobacco and alcohol, unhealthy diet, lack of physical activity, overweight and obesity, pollution (air, water, and soil), and stress. Regulation of these unhealthy behaviours plays a crucial role in blood pressure control among individuals on hypertensive treatment, especially those suffering from uncontrolled hypertension. Hence, the present study aims at identifying the unhealthy behaviours associated with uncontrolled hypertension.
