Finally, the review ends up with subjective views on present limitations and some appropriate advice for future research directions.

Neurological injury following successful resuscitation from sudden cardiac arrest (CA) is common. The pathophysiological basis of this injury remains poorly understood, and treatment options are limited. Microglial activation and neuroinflammation are established contributors to many neuropathologies, such as Alzheimer disease and traumatic brain injury, but their potential role in post-CA injury has only recently been recognized. Here, we hypothesize that microglial activation that occurs following brief asystolic CA is associated with neurological injury and represents a potential therapeutic target.

Adult C57BL/6 male and female mice were randomly assigned to 12-min, KCl-induced asystolic CA, under anesthesia and ventilation, followed by successful cardiopulmonary resuscitation (n = 19) or sham intervention (n = 11). Neurological assessments of mice were performed using standardized neurological scoring, video motion tracking, and sensory/motor testing. Mice were killed at 72h for histological studies; and the dentate gyrus of the hippocampus are evident following brief asystolic CA and are associated with severe neurological injury.

Meta-analyses of observational studies report a 1.1-1.7% pooled risk of stroke among patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection requiring hospitalization, but consultations for stroke and reperfusion procedures have decreased during the outbreak that occurred during the first half of the year 2020. It is still unclear whether a true increase in the risk of stroke exists among patients with coronavirus disease 2019 (COVID-19). SodiumLascorbyl2phosphate In-hospital ischemic stroke (IHIS) complicated the 0.04-0.06% of all admissions in the pre-COVID-19 era, but its incidence has not been assessed among inpatients with COVID-19. We aimed to compare IHIS incidence among patients with SARS-CoV-2 infection with that of inpatients with non-COVID-19 illnesses from the same outbreak period and from previous periods.

This historical cohort study belongs to the COVID-19@Vallecas cohort. The incidence of IHIS was estimated for patients with SARS-CoV-2 hospitalized during March-April 2020 [COVID-19 cohoe in the increased frequency of IHIS.

We investigated whether model-based indices of cerebral autoregulation (CA) are associated with outcomes after pediatric traumatic brain injury.

This was a retrospective analysis of a prospective clinical database of 56 pediatric patients with traumatic brain injury undergoing intracranial pressure monitoring. CA indices were calculated, including pressure reactivity index (PRx), wavelet pressure reactivity index (wPRx), pulse amplitude index (PAx), and correlation coefficient between intracranial pressure pulse amplitude and cerebral perfusion pressure (RAC). Each CA index was used to compute optimal cerebral perfusion pressure (CPP). Time of CPP below lower limit of autoregulation (LLA) or above upper limit of autoregulation (ULA) were computed for each index. Demographic, physiologic, and neuroimaging data were collected. Primary outcome was determined using Pediatric Glasgow Outcome Scale Extended (GOSE-Peds) at 12months, with higher scores being suggestive of unfavorable outcome. Univariate and multig CPP more than LLA based on wPRx may improve outcomes and warrants prospective investigation.

Children supported with extracorporeal membrane oxygenation (ECMO) have been shown to be at risk for developing seizures. However, previous studies have consisted of heterogeneous patient populations. We aimed to describe the rate of seizures in pediatric patients receiving ECMO for cardiac indications and to identify risk factors for the occurrence of this complication.

This is a retrospective cohort study of consecutive pediatric patients on ECMO for congenital or acquired cardiac disease between 2014 and 2018 at a tertiary care pediatric hospital.

We reviewed 110 children, of whom 104 (95%) received continuous electroencephalogram for at least 48h after ECMO initiation. Seizures were observed in 20 (18%) children. Seizures were subclinical only in 13 (65%) patients, and 8 (40%) developed status epilepticus. The median time from ECMO initiation to first seizure was 34h (25%, 75% 19, 44). Children with seizures were more likely to have suffered pre-ECMO cardiac arrest (odds ratio 5.7, 95% confidence inmetabolic acidosis.

Seizures in pediatric patients on ECMO for cardiac indications are common, occurring in nearly one in five patients. Seizures are frequently subclinical only and often progress to status epilepticus. Continuous electroencephalogram is therefore warranted for this patient population, especially in the setting of cardiac arrest, extracorporeal cardiopulmonary resuscitation, or severe metabolic acidosis.

We define dehydration and its relationship to pain physiology including both primary and secondary headache disorders.

Intravenous fluids administered for acute migraine attacks in an emergency department setting have not been shown to improve pain outcomes. However, increased intravascular volume before diagnostic lumbar puncture may reduce the frequency of post-lumbar puncture headache from iatrogenic spinal fluid leak. Maintenance of euhydration can help treat orthostatic and "coat-hanger" headache due to autonomic disorders. Similarly, prevention of fluid losses can mitigate secondary headaches provoked by dehydration such as cerebral venous thrombosis or pituitary apoplexy. Dehydration alone may cause headache, but oftentimes exacerbates underlying medical conditions such as primary headache disorders or other conditions dependent on fluid balance.

Metastasis is one of the most leading causes of death in these patients. Early-stage or locally advanced breast cancer is limited to the breast or nearby lymph nodes. When breast cancer spreads to farther tissues/organs from its original site, it is referred to as metastatic or stage IV breast cancer. Normal breast development is regulated by specific genes and signalling pathways controlling cell proliferation, cell death, cell differentiation and cell motility. Dysregulation of genes involved in various signalling pathways not only leads to the formation of primary tumour but also to the metastasis as well. The metastatic cascade is represented by a multi-step process including invasion of the local tumour cell followed by its entry into the vasculature, exit of malignant cells from the circulation and ultimately their colonization at the distant sites. These stages are referred to as formatediting technologies that can target specific genes in the affected areas by making knock-in and knock-out alternations and thereby bring significant treatment outcomes in breast cancer have also been summarized.

Since frameless stereotactic radiosurgery (SRS) techniques have been recently introduced, hypofractionated SRS (HF-SRS) for large brain metastases (BMs) is gradually increasing. To verify the efficacy and safety of HF-SRS for large BMs, we aimed to perform a systematic review and compared them with SF-SRS.

We systematically searched the studies regarding SF-SRS or HF-SRS for large (> 2cm) BM from databases including PubMed, Embase, and the Cochrane Library on July 31, 2018. Biologically effective dose with the α/β ratio of 10 (BED

), 1-year local control (LC), and radiation necrosis (RN) were compared between the two groups, with the studies being weighted by the sample size.

The 15 studies with 1049 BMs that described 1-year LC and RN were included. HF-SRS tended to be performed in larger tumors; however, higher mean BED

(50.1 Gy

versus 40.4 Gy

, p < 0.0001) was delivered in the HF-SRS group, which led to significantly improved 1-year LC (81.6 versus 69.0%, p < 0.0001) and 1-year overall survival (55.1 versus 47.2%, p < 0.0001) in the HF-SRS group compared to the SF-SRS group. In contrast, the incidence of radiation toxicity was significantly decreased in the HF-SRS group compared to the SF-SRS group (8.0 versus 15.6%, p < 0.0001).

HF-SRS results in better LC of large BMs while simultaneously reducing RN compared to SF-SRS. Thus, HF-SRS should be considered a priority for SF-SRS in patients with large BMs who are not suitable to undergo surgical resection.

Although it has a global distribution, there have been relatively few studies on PSV in domestic animals. We isolated a PSV strain, SHCM2019, from faecal specimens from swine, using PK-15 cells. To investigate its molecular characteristics and pathogenicity, the genomic sequence of strain SHCM2019 was analysed, and clinical manifestations and pathological changes occurring after inoculation of neonatal piglets were observed. The virus isolated using PK-15 cells was identified as PSV using RT-PCR, transmission electron microscopy (TEM), and immunofluorescence assay (IFA). Sequencing results showed that the full-length genome of the SHCM2019 strain was 7,567 nucleotides (nt) in length, including a 27-nucleotide poly(A) tail. Phylogenetic analysis demonstrated that this virus was a PSV isolate belonging to the Chinese strain cluster. Recombination analysis indicated that there might be a recombination breakpoint upstream of the 3D region of the genome. Pathogenicity experiments demonstrated that the virus isolate could cause diarrhoea and pneumonia in piglets. In breif, a recombinant PSV strain, SHCM2019, was isolated and shown to be pathogenic. Our results may provide a reference for future research on the pathogenic mechanism and evolutionary characteristics of PSV.The world often goes too fast for children with autism spectrum disorder (ASD) to process. We tested the therapeutic effectiveness of input slowing in children with ASD. Over 12 months, 12 children with ASD had weekly speech therapy sessions where stimuli were slowly played on a PC, while 11 age- and level-matched children with ASD had speech therapy using real-time stimuli. At the beginning and end of the study, all participants were assessed on communication, imitation, facial emotion recognition, behavior, and face exploration. Whereas communication and facial emotion recognition improved in both groups, imitation increased, inappropriate behaviors decreased, and time spent fixating mouth and eyes increased solely in the group using slowness. Slowness therapy seems very promising for ASD children.
