Associations Between Two Single-Nucleotide Polymorphisms in NINJ2 Gene and Risk of Psychiatric Disorders
AbstractNINJ2 encodes a transmembrane protein that contributes in neurodevelopment and regeneration of neurons. Single-nucleotide polymorphisms (SNPs) within this gene have been associated with Alzheimer ’s disease, ischemic stroke, and multiple sclerosis. The rs11833579 and rs3809263 SNPs have been associated with risk of ischemic stroke in Iranian population. While theNINJ2 rs12425791 has been with risk of ischemic stroke in East Asian population, the rs11833579 has not been associated with this condition either in East Asian population or Chinese Han population. In the current project, we genotyped rs11833579 and rs38...

Poststroke Bipolar Disorder
Various diseases that impact different systems and organs in the body may trigger manic episodes. Strokes are often associated with psychiatric symptoms, particularly depressive and, more rarely, manic. We herein report a case of bipolar disorder secondary to cerebrovascular disease in a 67-year-old man with no personal or family history of psychiatric illness who, at the age of 64, had a bilateral ischemic stroke in the middle cerebral artery territory. About 20 days after this stroke, he experienced a manic episode. Three years later, he experienced a second manic episode, with another hospitalization in a psychiatric wa...

Phosphorylation of PI3K/Akt at Thr308, but not MAPK kinase, mediates lithium-induced neuroprotection against cerebral ischemia in mice
Exp Neurol. 2022 Feb 2:113996. doi: 10.1016/j.expneurol.2022.113996. Online ahead of print.ABSTRACTLithium, in addition to its effect on acute and long-term bipolar disorder, is involved in neuroprotection after ischemic stroke. Yet, its mechanism of action is still poorly understood, which was only limited to its modulatory effect on GSK pathway. Therefore, we initially analyzed the dose-dependent effects of lithium on neurological deficits, infarct volume, brain edema and blood-brain barrier integrity, along with neuronal injury and survival in mice subjected to focal cerebral ischemia. Thereafter, we investigated the in...

Valproic Acid: A New Candidate of Therapeutic Application for the Acute Central Nervous System Injuries.
Abstract Acute central nervous system (CNS) injuries, including stroke, traumatic brain injury (TBI), and spinal cord injury (SCI), are common causes of human disabilities and deaths, but the pathophysiology of these diseases is not fully elucidated and, thus, effective pharmacotherapies are still lacking. Valproic acid (VPA), an inhibitor of histone deacetylation, is mainly used to treat epilepsy and bipolar disorder with few complications. Recently, the neuroprotective effects of VPA have been demonstrated in several models of acute CNS injuries, such as stroke, TBI, and SCI. VPA protects the brain from injury p...

Can forearm muscle activity be selectively recorded using conventional surface EMG-electrodes in transcranial magnetic stimulation? A feasibility study
Conclusion: Neither with peripheral electrical stimulation nor with TMS it was possible to selectively record extensor or flexor forearm muscle activity using conventional surface EMG-electrodes.Significance: Despite this negative result, the important role of the forearm extensor muscles in the prognosis of motor recovery after stroke warrants further research into novel methods for selectively recording muscle activity in TMS other than by conventional surface EMG.

Preliminary Evidence of Disparities in Physical Activity among Adolescents with Bipolar Disorder
Conclusions Frontal-executive dysfunction implicates frontal brain regions, which are known to be susceptible to oxidative damage. Further studies are needed, and those examining psychiatric populations may be especially fruitful. Focusing on youth may yield enhanced signal detection. Further study is needed to identify which antioxidant interventions work best for which cognitive functions and for which patients.

Impact of Atrial Fibrillation Duration on the Success of First-Time Concomitant Cox Maze Procedures
Conclusions Longer AF duration significantly impacted CM success and may result from extensive tissue remodeling. Patients with longer AF duration can expect reasonable success rates, especially when on AAD, and low stroke rates during follow-up. Cryoablation may reduce AF duration impact on success compared with combined bipolar radiofrequency and cryothermia.

HRS 2016 roundup: Leadless pacers at the fore
Medtronic (NYSE:MDT) and St. Jude Medical (NYSE:STJ), aiming to distinguish their respective leadless pacemaker offerings, presented new data last week in San Francisco at the Heart Rhythm Society’s annual meeting. St. Jude said a subset of data from the Leadless II trial showed that its Nanostim device was was successfully retrieved in 14 patients up to 3.2 years after implantation, with no serious adverse events. “We’ve now shown that for patients requiring device upgrades or new leadless pacing options, late retrievability – even up to 3 years – is possible with the Nanostim leadless pacemak...
