AI Article Synopsis
- The study introduces the TOT-AL, a new online tool for measuring past week alcohol consumption, and evaluates its reliability and accuracy compared to traditional face-to-face methods.
- Students tested the tool twice in one day and also participated in both online and in-person interviews to assess its effectiveness.
- Results show a very strong correlation between the TOT-AL results and face-to-face measurements, indicating that the tool is reliable and efficient for online alcohol consumption assessment, particularly for those with internet access.
Article Abstract
Objective: This paper reports on the development of a new online measure of beverage-specific past week alcohol consumption (the TOT-AL), its test-retest reliability, and comparability with the face-to-face approach of ascertaining alcohol intake.
Methods: University students participating in the reliability study completed the TOT-AL twice on the same day with at least 3 h apart. Students in the comparability study attended a face-to-face interview and completed the TOT-AL on the same day, in a randomised order, at least 3 h apart.
Results: There was a strong correlation between the repeated measurements of the TOT-AL (r=0.99; 95% CI: 0.98, 0.99) and between the units calculated by the TOT-AL and the face-to face interview (r=0.97; 95% CI: 0.95, 0.99). A high level of agreement between measurements was also observed in a Bland-Altman analysis.
Conclusions: The TOT-AL is a reliable, time efficient means of ascertaining alcohol intake, equivalent to that obtained face-to-face. These findings support the use of this approach to online alcohol assessment in populations with access to the Internet.

Background: Preferred walking speed (PWS), maximal walking speed (MWS), and walking speed reserve (WSR)-the difference between MWS and PWS-can be easily obtained from the 10-m walk test (10MWT) to assess walking ability and function. However, their test-retest reliability has not been determined in persons with unilateral lower-limb amputation (LLA).
Objectives: To determine the reliability of the PWS, MWS, and WSR obtained from the 10MWT in persons with LLA.
Electrochemical aptasensor based on zirconium/copper oxides embedded in mesoporous carbon derived from bimetallic metal-organic framework for ultrasensitive detection of miR-21.

A novel electrochemical aptasensor based on bimetallic zirconium and copper oxides embedded within mesoporous carbon (denoted as ZrOCuO@mC) was constructed to detect miRNA. The porous ZrOCuO@mC was created through the pyrolysis of bimetallic zirconium/copper-based metal-organic framework (ZrCu-MOF). The substantial surface area and high porosity of ZrOCuO@mC nanocomposite along with its robust affinity toward aptamer strands, facilitated the effective anchoring of aptamer strands on the ZrOCuO@mC-modified electrode surface.
