Insights into the dependence of post-stroke motor recovery on the initial corticospinal tract connectivity from a computational model.

There is a consensus that motor recovery post-stroke primarily depends on the degree of the initial connectivity of the ipsilesional corticospinal tract (CST). Indeed, if the residual CST connectivity is sufficient to convey motor commands, the neuromotor system continues to use the CST predominantly, and motor function recovers up to 80%. In contrast, if the residual CST connectivity is insufficient, hand/arm dexterity barely recovers, even as the phases of stroke progress.

The serotonergic psychedelic N,N-dipropyltryptamine alters information-processing dynamics in in vitro cortical neural circuits.

Most of the recent work in psychedelic neuroscience has been done using noninvasive neuroimaging, with data recorded from the brains of adult volunteers under the influence of a variety of drugs. While these data provide holistic insights into the effects of psychedelics on whole-brain dynamics, the effects of psychedelics on the mesoscale dynamics of neuronal circuits remain much less explored. Here, we report the effects of the serotonergic psychedelic N,N-diproptyltryptamine (DPT) on information-processing dynamics in a sample of in vitro organotypic cultures of cortical tissue from postnatal rats.

Anaesthesia and climate change: time to wake up? A rapid qualitative appraisal exploring the views of anaesthetic practitioners regarding the transition to TIVA and the reduction of desflurane.

Background: The National Health Service (NHS) has pledged to reach carbon net-zero by 2040. In alignment with this goal, a London hospital's anaesthesia department is actively reducing desflurane use and transitioning towards total intravenous anaesthesia (TIVA) as a sustainable alternative, contributing to environmentally responsible practices within the healthcare sector.

Methods: We conducted a rapid qualitative appraisal through online interviews with 17 anaesthetic practitioners to explore their perspectives regarding this climate change mitigation strategy.

Palliative care for older adults with cardiovascular disease.

Heart disease is the number one cause of death in the United States. Advanced cardiac conditions, such as heart failure, are characterized by severe symptoms, recurrent hospitalizations, limited/uncertain prognosis, decreased quality of life, and high levels of caregiver burden. The burden of heart failure is highest in older adults, for whom cardiovascular symptoms are layered on existing age-related problems such as geriatric syndromes, polypharmacy, depression, frailty, inadequate social support, decreased representation in clinical trials, and aging caregivers.
