Objectives: Aging entails deterioration in sensory, physical, and cognitive functions, raising doubt in the driving capacity of older drivers, especially when the deficits are severe, as in dementia. Many older drivers, especially women, adapt their driving habits in order to compensate for these deficits and eventually stop driving. The present prospective study assessed driving cessation in men and women throughout the dementia process, including a 2-year pre-dementia phase.
Methods: The study was based on a three-city cohort of subjects who were aged 65 years and older in 2000 and followed for more than 10 years. Active dementia detection was conducted at each follow-up. The probability of driving cessation was assessed in men and women during the 2-year pre-dementia phase and until 5 years after diagnosis.
Results: In the 2-year pre-dementia phase, both men and women ceased driving earlier than drivers with no central nervous system pathology (p < 0,001), and women ceased driving earlier than men. A total of 45% of men and 74% of women had already ceased driving at dementia diagnosis. In contrast, the probability of cessation within 3 years after diagnosis was similar between men and women.
Conclusion: The study showed that, in this French urban population, few demented drivers, especially women, were still driving after diagnosis. Those who continued to drive 3 years after the diagnosis all had Alzheimer-type dementia. There is certainly a need for physicians to help these drivers to adapt their driving activity to their deficits and to prepare them to stop driving. Copyright © 2016 John Wiley & Sons, Ltd.

Background: Identification of mother-infant pairs predisposed to early cessation of exclusive breastfeeding is important for delivering targeted support. Machine learning techniques enable development of transparent prediction models that enhance clinical applicability. We aimed to develop and validate two models to predict cessation of exclusive breastfeeding within one month among infants born after 35 weeks gestation using machine learning techniques.

Flow cessation leads to severe degradation of river corridor landscape structure, habitat quality, and ecological functions. This study focuses on the representative river with ceased flow in northern China, the Yongding River plain section. Utilizing long-term, high-resolution satellite remote sensing imagery and the InVEST model, we analyzed the spatiotemporal evolution of landscape structure and habitat quality (HQ) before and after river corridor flow cessation over the past 50 years.

Article Synopsis
- Cellular senescence is the process where cells permanently stop dividing and secrete inflammatory factors, known as the senescence-associated secretory phenotype (SASP), which can contribute to aging and diseases.
- Recent studies show that senescent cells can also play important roles in tumor suppression, tissue development, and repair, highlighting their dual nature.
- The review discusses potential therapies called senolytic agents that target harmful senescent cells while balancing the benefits of transient senescence to improve health as we age.

Background: Existing research highlights an increase in psychedelic microdosing, particularly for therapeutic purposes and as a means for self-enhancement. However, we know little about the different routes into and out of microdosing, particularly by those who do not consume other illicit substances, and of the processes involved in the development, maintenance, and cessation of practices.
Methods: Drawing upon a trans-national interview-based study of 23 participants actively microdosing (n = 19), about to start (n = 3), or who were past users (n = 1), we develop a phased-based analysis of different user pathways.
