Abstract
Background Acute stroke is an important cause of morbidity and mortality. Myocardial injury is an important complication of acute cerebrovascular events. Neurogenic stress cardiomyopathy (NSC) is a condition of acute myocardial systolic dysfunction that can be observed after acute cerebrovascular events. Objective In this study, we aimed to investigate the relationship between myocardial function assessed by two-dimensional speckle-tracking echocardiography and National Institutes of Health Stroke Scale (NIHSS) score in patients with acute ischemic stroke. Materials and Methods This cross-sectional study screened 97 patients (males, 42; females, 55; 65 ± 16 years) with acute ischemic stroke. Around 17 patients were excluded and 80 patients were studied. Patients were divided into two groups based on the calculated NIHSS score (Group 1, NIHSS score <16; Group 2, NIHSS score ≥16). Demographic, clinical, and laboratory data for all patients were collected. Cardiac function was evaluated by two-dimensional speckle tracking echocardiography within 48 h of admission to the neurology care unit. Results There were no significant differences in the demographic parameters of patients. The absolute value of global longitudinal systolic strain (GLS) was significantly higher in Group 1 patients than in Group 2 patients (21.4 ± 2.2 vs 15.9 ± 2.7, P = 0.0281). We found that thirteen patients (22%) had normal LVEF and abnormal LV GLS in Group 1 (P = 0.036). Eight patients (36%) had normal LVEF and abnormal LV GLS in Group 2 (P = 0.042). E/e', QT on ECG, and serum troponin levels were significantly higher in Group 2 patients than in Group 1 patients (P < 0.05). Conclusions Our results suggest that GLS is associated with stroke severity on admission in patients with acute ischemic stroke. GLS is an indicator of myocardial deformation with a different from LVEF. GLS can detect early myocardial dysfunction despite preserved LVEF.

Abstract
BACKGROUND Pediatric brain injury is accompanied by hemodynamic perturbations complicating the optimization of cerebral physiology. Point-of-care ultrasound (POCUS) uses dynamic real-time imaging to complement the physical examination and identify hemodynamic abnormalities in preload, contractility, and afterload conditions, but the contribution of cardiac POCUS in the context of pediatric brain injury is unclear. METHODS We reviewed cardiac POCUS images integrated in clinical care to examine those with neurological injury and hemodynamic abnormalities. RESULTS We discuss three children with acute brain injury and myocardial dysfunction identified using cardiac POCUS by bedside clinicians. CONCLUSIONS Cardiac POCUS may have an important role in caring for children with neurologic injury. These patients received personalized care informed by POCUS data in attempts to stabilize hemodynamics and optimize clinical outcomes.

Abstract
OBJECTIVE Myocardial speckle-tracking echocardiography can detect subtle abnormalities in the left atrial function. In this study, we aimed to investigate the relationship between left atrial myocardium and tissue function n assessed by two-dimensional speckle-tracking echocardiography and the National Institutes of Health Stroke Scale score in patients with acute ischemic stroke. METHOD The study was composed of 80 patients (45 men, 35 women, mean age: 67±15 years) with acute ischemic stroke. The patients were divided into two groups based on the calculated National Institutes of Health Stroke Scale score (group 1, National Institutes of Health Stroke Scale score < 16; group 2, National Institutes of Health Stroke Scale score ≥ 16). Demographic, clinical, and laboratory data for all patients were collected. Cardiac functions were evaluated using two-dimensional speckle-tracking echocardiography within 48 hours from admission to the neurology care unit. RESULTS There were no significant differences between the patients' clinical parameters. Left ventricular ejection fraction was significantly higher in group 1 than in group 2 (59.2±5.6 to 51.4±6.3, p=0.024). Left atrial longitudinal strain was significantly higher in group 1 than in group 2 (34.48±9.73 to 26.27±7.41, p=0.019). There were no significant differences between other echocardiographic parameters. CONCLUSION Our results suggest that left atrial longitudinal strain is associated with stroke severity during admission in patients with acute ischemic stroke. Left atrial longitudinal strain is an indicator of left atrial myocardial function.

Abstract
Extracerebral complications, especially pulmonary and cardiovascular, are frequent in brain-injured patients and are major outcome determinants. Two major pathways have been described: brain-lung and brain-heart interactions. Lung injuries after acute brain damages include ventilator-associated pneumonia (VAP), acute respiratory distress syndrome (ARDS) and neurogenic pulmonary œdema (NPE), whereas heart injuries can range from cardiac enzymes release, ECG abnormalities to left ventricle dysfunction or cardiogenic shock. The pathophysiologies of these brain-lung and brain-heart crosstalk are complex and sometimes interconnected. This review aims to describe the epidemiology and pathophysiology of lung and heart injuries in brain-injured patients with the different pathways implicated and the clinical implications for critical care physicians.

Abstract
Background Cerebral-cardiac syndrome, newly developed cardiac damage manifestations subsequent to cerebral injuries, is a common complication of stroke and leads to increased morbidity and mortality. The current study is aimed to develop a risk prediction scale to stratify high-risk population of CCS among ischemic stroke patients. Methods The study included 410 cases from four tertiary medical centers from June 2018 to April 2019. The risk prediction model was established via logistic regression from the derivation cohort including 250 cases admitted between June 2018 and December 2018. Another 160 cases admitted from January 2019 to April 2019 were included as the validation cohort for external validation. The performance of the model was determined by the area under curve of the receiver operating characteristic curve. A rating scale was developed based on the magnitude of the logistic regression coefficient. Results The prevalence of CCS was 55.2% in our study. The predictive model derived from the derivation cohort showed good calibration by Hosmer-Lemeshow test (P = 0.492), and showed sensitivity of 0.935, specificity of 0.720, and Youden index of 0.655. The C-statistic for derivation and validation cohort were 0.888 and 0.813, respectively. Our PANSCAN score (0 to 10 points) was then established, which consists of the following independent risk factors: PT(12 s–14 s = 0; otherwise = 1), APTT(30s–45s = 0, otherwise = 1), Neutrophils(50–70% = 0; otherwise = 1), Sex(female = 1), Carotid artery stenosis(normal or mild = 0; moderate to severe = 2), Age(≥65 years = 1), NIHSS score(1 to 4 = 2; ≥5 = 3). Patients scored 3 or more points were stratified as high risk. Conclusion The risk prediction model showed satisfactory prediction effects. The PANSCAN scale provides convenient reference for preventative treatment and early management for high-risk patients. Trial registration The study was retrospectively registered in Chinese Trial Registry. The date of registration is April 17, 2019. Trial registration number: ChiCTR1900022587.

Abstract
Myocardial infarction (MI) is defined as myocardial cell death due to prolonged myocardial ischemia. Clinically, troponin rise and/or fall have become the “defining feature of MI” according to the universal definition of MI (UD-MI). Takotsubo syndrome (TS) and TS-related disease conditions also cause troponin elevation with typical rise and/or fall pattern but through a mechanism other than coronary ischemia. By strict application of the clinical diagnostic criteria for type-1 MI, type-2 MI, type-3 MI, and MI with non-obstructive coronary arteries according to the UD-MI including the fourth one published recently, TS and most of the 26 other causes of troponin elevation mentioned in the fourth UD-MI may erroneously be classified as MI. The existing evidence argues for the case that TS by itself is not a MI. Hyper-activation of the autonomic-sympathetic nervous system including local cardiac sympathetic hyper-activation and disruption with nor-epinephrine churn and spillover is the most probable cause of TS. This autonomic neuro-cardiogenic (ANCA) mechanism results in myocardial “cramp” (stunning), the severity and duration of which depend on the degree of the sympathetic-hyperactivation and nor-epinephrine spillover. The myocardial cramp may squeeze the cytosolic free troponin pools causing mild to moderate troponin elevation in TS and TS-related disease conditions. This ANCA syndrome, which has hitherto been enveloped by the UD-MI over more than one decade, may occur in acute, recurrent, and chronic forms. In this critical review, the controversies of UD-MI, evidence for ANCA syndrome, and a hypothetical mechanism for the troponin elevation in ANCA syndrome are provided.

Inhibition of microRNA-124-3p as a novel therapeutic strategy for the treatment of Gulf War Illness: Evaluation in a rat model. Neurotoxicology 2018; 71:16-30.

Abstract
Gulf War Illness (GWI) is a chronic, multisymptom illness that continues to affect up to 30% of veterans deployed to the Persian Gulf during the 1990-1991 Gulf War. After nearly 30 years, useful treatments for GWI are lacking and underlying cellular and molecular mechanisms involved in its pathobiology remain poorly understood, although exposures to pyridostigmine bromide (PB) and pesticides are consistently identified to be among the strongest risk factors. Alleviation of the broad range of symptoms manifested in GWI, which involve the central nervous system, the neuroendocrine system, and the immune system likely requires therapies that are able to activate and inactivate a large set of orchestrated genes. Previous work in our laboratory using an established rat model of GWI identified persistent elevation of microRNA-124-3p (miR-124) levels in the hippocampus whose numerous gene targets are involved in cognition-associated pathways and neuroendocrine function. This study aimed to investigate the broad effects of miR-124 inhibition in the brain 9 months after completion of a 28-day exposure regimen of PB, DEET (N,N-diethyl-3-methylbenzamide), permethrin, and mild stress by profiling the hippocampal expression of genes known to play a critical role in synaptic plasticity, glucocorticoid signaling, and neurogenesis. We determined that intracerebroventricular infusion of a miR-124 antisense oligonucleotide (miR-124 inhibitor; 0.05-0.5 nmol/day/28 days), but not a negative control oligonucleotide, into the lateral ventricle of the brain caused increased protein expression of multiple validated miR-124 targets and increased expression of downstream target genes important for cognition and neuroendocrine signaling in the hippocampus. Off-target cardiotoxic effects were revealed in GWI rats receiving 0.1 nmol/day as indicated by the detection in plasma of 5 highly elevated protein cardiac injury markers and 6 upregulated cardiac-enriched miRNAs in plasma exosomes determined by next-generation sequencing. Results from this study suggest that in vivo inhibition of miR-124 function in the hippocampus is a promising, novel therapeutic approach to improve cognition and neuroendocrine dysfunction in GWI. Additional preclinical studies in animal models to assess feasibility and safety by developing a practical, noninvasive drug delivery system to the brain and exploring potential adverse toxicologic effects of miR-124 inhibition are warranted.
