Association between skin sympathetic nerve activity and electrocardiogram alterations after subarachnoid hemorrhage.

While autonomic dysregulation and repolarization abnormalities are observed in subarachnoid hemorrhage (SAH), their relationship remains unclear. We aimed to measure skin sympathetic nerve activity (SKNA), a novel method to estimate stellate ganglion nerve activity, and investigate its association with electrocardiogram (ECG) alterations after SAH. We recorded a total of 179 SKNA data from SAH patients at three distinct phases and compared them with 20 data from controls.

Objective: The study aims to investigate the long-term impacts of traumatic brain injury (TBI) on neuroinflammation and neuronal apoptosis in pediatric and adult mice, specifically focusing on how age-at-injury influences these processes.
Methods: Controlled cortical impact (CCI) was used to induce TBI in pediatric (21-25 days old) and adult (8-12 weeks old) C57Bl/6 male mice. Neuroinflammation was evaluated through immunoreactivity for Iba-1 and GFAP, while apoptosis was assessed using markers such as Bax, Bcl- 2, and pro-caspase-3.
Constitutive loss of kynurenine-3-monooxygenase changes circulating kynurenine metabolites without affecting systemic energy metabolism.

Kynurenic acid (KYNA) and quinolinic acid (QUIN) are metabolites of the kynurenine pathway of tryptophan degradation with opposing biological activities in the central nervous system. In the periphery, KYNA is known to positively affect metabolic health, whereas the effects of QUIN remain less explored. Interestingly, metabolic stressors, including exercise and obesity, differentially change the balance between circulating KYNA and QUIN.

As infants suffer significant morbidity and mortality due to norovirus-related acute gastroenteritis (AGE), we assessed four formulations of the bivalent virus-like particle (VLP) vaccine candidate (HIL-214) in Panamanian and Colombian infants. 360 infants aged 6 weeks to 5 months were randomly allocated to 8 groups to receive three doses of HIL-214 or two doses of HIL-214 and one dose of placebo (Days 1, 56 and 112), where HIL-214 doses contained 15/15, 15/50, 50/50 or 50/150 μg of GI.1/GII.

Purpose: To report a case of transient diplopia and upgaze paresis in the setting of acute dorsal midbrain infarcts from a cervical vertebral artery dissection in an otherwise healthy man.
Observations: A 33-year old man presented to the ophthalmology urgent clinic with a 1 h history of blurred and double vision, asthenopia, and a mild focal left posterior headache. Ocular motility examination revealed a profound upgaze palsy and convergence-retraction horizontal jerk nystagmus in attempted upgaze that gradually improved over the course of 1 h.
