AI Article Synopsis
- The study aimed to evaluate a neuropsychological assessment battery to determine if it could effectively predict driving ability in individuals with cognitive impairments.
- 104 individuals with various cognitive impairments participated in the study, which compared their performance on the assessment battery to actual on-road driving tests.
- The assessment battery showed a moderate ability to predict driving performance, with specific tests correlating significantly with outcomes, supporting the use of multiple assessments to evaluate a person's fitness to drive.
Article Abstract
Primary Objective: The study evaluated a neuropsychological assessment battery used to assess fitness to drive in cognitively impaired individuals and hypothesized that the battery would be associated with on-road outcome measures. A secondary aim was to explore the relationships between individual neuropsychological tests and driving performance.
Research Design: The study used a cross-sectional design in which a sample of individuals with various types of cognitive impairment completed the test battery and an on-road driving test.
Methods And Procedures: Performance on the test battery was compared to on-road driving performance in 104 individuals with acquired cognitive impairment.
Main Outcomes And Results: The battery had 73% sensitivity and 76% specificity in terms of agreement with the 'pass/fail' classification of the on-road driving test. Scores on the battery accounted for 18% of the variance in the total number of corrective interventions performed by a driving instructor during the on-road test. Most tests correlated significantly with driving test outcomes. While one test, the Rey Complex Figure Test, emerged as an independent predictor of driving performance in multiple regression analyses, the variance explained by this single test was small.
Conclusions: The results provide support for the use of a battery approach to assess fitness to drive.

Introduction: Driving safety may be compromised in people with dementia or mild cognitive impairment (MCI). Occupational therapists assess and screen for driving safety in older people with cognitive impairment. However, little is known about their perspectives relating to these assessments.

Oncogenic mutations that drive colorectal cancer can be present in healthy intestines for long periods without overt consequence. Mutation of Adenomatous polyposis coli (Apc), the most common initiating event in conventional adenomas, activates Wnt signalling, hence conferring fitness on mutant intestinal stem cells (ISCs). Apc mutations may occur in ISCs that arose by routine self-renewal or by dedifferentiation of their progeny.

Drugged driving is associated with an increased risk of road accidents worldwide. In Italy, driving under the influence (DUI) of alcohol and drugs is a reason for driving disqualification or revocation of the driving license. Drivers charged with driving under the influence of alcohol and drugs must attend a Local Medical Commission (LMC) to undergo mandatory examinations to regain the suspended license.

Plant microbiomes have a major influence on forest structure and functions, as well as tree fitness and evolution. However, a comprehensive understanding of variations in fungi along the soil-plant continuum, particularly within tree seedlings, under global warming is lacking. Here, we investigated the dynamics of fungal communities across different compartments (including bulk soil and rhizosphere soil) and plant organs (including the endosphere of roots, stems and leaves) of Schima superba seedlings exposed to experimental warming and drought using AccuITS absolute quantitative sequencing.

The long-term stability of many gut microbiome strains within the microbiome suggests the existence of strain-specific strategies that have evolved to foster resilience to such insults. Despite this, little is known about the mechanisms that mediate this resistance.
