Simvastatin, but Not Atorvastatin, Is Associated with Higher Peak Rivaroxaban Serum Levels and Bleeding: an Asian Cohort Study from Singapore
ConclusionOur findings suggest that concomitant use of simvastatin with rivaroxaban may be associated with bleeding events in an Asian cohort. Further studies using physiologically based pharmacokinetic modelling are required to investigate the drug-drug interactions between these drugs.

Post-Stroke Lateropulsion: Resolution and Function After Discharge From Inpatient Rehabilitation - A Cohort Study
CONCLUSIONS: Lateropulsion can continue to resolve after discharge from inpatient rehabilitation. Larger cohort studies are needed to further explore associations between persistent lateropulsion and long-term outcomes.PMID:37736404 | PMC:PMC10510537 | DOI:10.3138/ptc-2021-0078

PPP1R12C Promotes Atrial Hypocontractility in Atrial Fibrillation
CONCLUSIONS: Patients with AF exhibit increased levels of PPP1R12C protein compared with controls. PPP1R12C overexpression in mice increases PP1c targeting to MLC2a and causes MLC2a dephosphorylation, which reduces atrial contractility and increases AF inducibility. These findings suggest that PP1 regulation of sarcomere function at MLC2a is a key determinant of atrial contractility in AF.PMID:37737016 | DOI:10.1161/CIRCRESAHA.123.322516

The prevalence and prognosis of asymptomatic intracranial atherosclerosis in a community-based population: Results based on high-resolution magnetic resonance imaging
CONCLUSIONS: We found that ICAD detected using HR-MRI increases the long-term risk of a first-ever ischemic stroke in a stroke-free population, suggesting that the current primary prevention protocol of stroke awaits further optimization.PMID:37738517 | DOI:10.1111/ene.16057

Scoping Review on Brain-Computer Interface-Controlled Electrical Stimulation Interventions for Upper Limb Rehabilitation in Adults: A Look at Participants, Interventions, and Technology
CONCLUSIONS: Future BCI-ES interventional studies could address this gap. Additionally, standardization of device and rehabilitation modalities, and study-appropriate involvement with therapists, can be considered to advance this intervention towards clinical implementation.PMID:37736411 | PMC:PMC10510539 | DOI:10.3138/ptc-2021-0074

Dense dopaminergic innervation of the peri ‐infarct cortex despite dopaminergic cell loss after a pure motor‐cortical stroke in rats
In this study, we assessed the reorganization of dopaminergic innervation of the PIC in a rat model of focal cortical stroke. Our data suggest a sprouting of dopaminergic fibers into the PIC and point to a role for dopaminergic signaling in reparative mechanisms post-stroke, potentially related to recovery. AbstractAfter ischemic stroke, the cortex directly adjacent to the ischemic core (i.e., the peri-infarct cortex, PIC) undergoes plastic changes that facilitate motor recovery. Dopaminergic signaling is thought to support this process. However, ischemic stroke also leads to the remote degeneration of dopaminergic midbrai...

Perceived performance of activities of daily living by stroke patients: key in decision to call EMS and outcomes
ConclusionPerception of unimpaired performance of ADL is a crucial barrier to appropriate help-seeking behavior after acute stroke, leading to undertreatment and less improvement in clinical symptoms. Thus, beyond improving the public’s knowledge of stroke symptoms, future public education campaigns should focus on the need for calling the EMS in case of stroke symptoms even if daily activities do not seem to be severely impaired.

Prospective analysis of video head impulse tests in patients with acute posterior circulation stroke
ConclusionSignificantly abnormal vHIT results were rare in patients with acute PCS, even in the presence of DBS. Moreover, vHIT effectively differentiated dizziness between PCS and VN, highlighting its potential for aiding differential diagnosis of acute dizziness.

Alterations in the preferred direction of individual arm muscle activation after stroke
DiscussionThese findings imply that alterations in the preferred direction of individual muscle activation contribute to various aspects of motor deficit following stroke. This insight may serve as a foundation for the development of innovative stroke neurorehabilitation approaches that take into account specific attributes of individual muscle activation, including their preferred activation direction.

To block or not to block: Targeting SK channels in diseased hearts
Atrial fibrillation (AF) is the most common arrhythmia, affecting more than 1% of general population and reaching over 10% in advanced age in the USA. Atrial fibrillation drastically increases the risk of stroke and promotes development of cardiomyopathy and congestive heart failure. Existing pharmacological approaches using β-blockers and inhibitors of Na+, Ca2+ and K+ channels to treat AF are effective only in 50% of cases. Furthermore, these drugs could affect ventricular tissue promoting proarrhythmic changes in electrical conduction, intracellular Ca2+ homeostasis, or action potential duration (APD).

Hemispheric Asymmetry in TMS-Induced Effects on Spatial Attention: A Meta-Analysis
AbstractHemispheric asymmetry is a fundamental principle in the functional architecture of the brain. It plays an important role in attention research where right hemisphere dominance is core to many attention theories. Lesion studies seem to confirm such hemispheric dominance with patients being more likely to develop left hemineglect after right hemispheric stroke than vice versa. However, the underlying concept of hemispheric dominance is still not entirely clear. Brain stimulation studies using transcranial magnetic stimulation (TMS) might be able to illuminate this concept. To examine the putative hemispheric asymmetr...

Electrocardiogram alterations in non-traumatic brain injury: a systematic review
AbstractThe presence of abnormal electrocardiograms in individuals without known organic heart disease is one of the most common manifestations of cardiac dysfunction occurring during acute non traumatic brain injury. The primary goal of the present review is to provide an overview of the available data and literature regarding the presence of new-onset electrocardiographic (ECG) alterations in acute non traumatic brain injury. The secondary aim is to identify the incidence of ECG alterations and consider the prognostic significance of new-onset ECG changes in this setting. To do so, English language articles from January ...
