Abstract 567: Combined Treatment With Irbesartan and Vitamin D Retards Renal Injury in Salt-loaded Uni-nephrectomized Stroke-prone Spontaneously Hypertensive Rats Poster Session II
Vitamin D diminishes renin expression. In addition, we previously reported that vitamin D increased renal expression of klotho in rats with normal kidney function. In the present study, effects of vitamin D on renal injury was assessed in four groups of rats (n=6-8 for each group); uni-nephrectomized stroke-prone spontaneously hypertensive rats fed high salt (6%) diet as a control (C), those treated with irbesartan (100 mg/kg/day) (I), rats treated with calcitriol (30 ng/kg/day) (V), and rats treated with both irbesartan and calcitriol (I+V). Six weeks later, rats were killed with over-anesthesia, and harvested right kidne...

Epidermal Growth Factor Receptor Is Critical For Angiotensin II-Mediated Hypertrophy in Cerebral Arterioles Renin-Angiotensin System
We examined the molecular mechanism of Ang II–mediated cerebrovascular remodeling that involves the epidermal growth factor receptor (EGFR) pathway. Mutant EGFR mice (waved-2), their heterozygous control (wild-type [WT]), and C57BL/6J mice were infused with Ang II (1000 ng kg–1 min–1) or saline via osmotic minipumps for 28 days (n=8 per group). Eight of the Ang II–infused C57BL/6J mice were cotreated with AG1478 (12 mg/kg per day, IP), a specific EGFR tyrosine kinase inhibitor. Systolic arterial pressure was measured by a tail-cuff method. Pressure and diameter of cerebral arterioles were measured t...

Abstract P159: Effect of Pharmacological Kinin Receptor Activation on Brain Damage and Mortality in Experimental Cerebral Ischemia in Non-diabetic and Diabetic Mice Session Title: Cerebrovascular Disease and Stroke
Brain ischemia is a major complication of arterial diseases and has a poorer prognosis in diabetic patients. As activation of the kallikrein-kinin system has been shown to enhance cardiac and renal tolerance to ischemia we tested effect of kinin receptor activation by pharmacological agonists, selective B1R or B2R, in a mouse model of transient middle cerebral artery occlusion [C57bl6 male, 10 week-old, anaesthesia, occlusion 60 min (MCAO)]. Treatment with the B1R agonist NG29 (B1Rago) or the B2R agonist NG291 (B2Rago) was started at reperfusion using osmotic micropumps. Neurological deficit (ND) was evaluated at 1 and 2 d...

Perioperative stroke following TURP: high index of suspicion and stabilization of physiological parameters can save lives
We report a case of a 72 year old hypertensive male who developed severe hypertension followed by neurological deterioration in the immediate postoperative period after TURP. While arterial blood gas and laboratory tests excluded TURP syndrome or any other metabolic cause, reduction of blood pressure failed to ameliorate the symptoms. A cranial CT done 4h after the onset of neurological symptoms revealed bilateral gangliocapsular and right thalamic infarcts. Oral aspirin was advised to prevent early recurrent stroke. Supportive treatment and mechanical ventilation ensured physiological stability and the patient recovered c...

Letter to the Editor: Pneumocephalus: Is the needle size significant?
Discussion. Pneumocephalus is defined by two mechanisms: a ball-valve and an inverted bottle concept.1 The ball-valve type implies positive pressure events, such as coughing or valsalva maneuvers, that prevent air escape. Tension pneumocephalus is included in this mechanism, causing a parenchymal mass effect. The inverted bottle theory includes a negative intracranial pressure gradient following cerebrospinal fluid drainage, relieved by air influx. A small pneumocephalus is usually sealed by blood clots or granulation, allowing spontaneous reabsorption and resolution.[1] Otherwise, the lateral positioning of a patient duri...

Perioperative stroke following transurethral resection of prostate: high index of suspicion and stabilization of physiological parameters can save lives
We report a case of a 72 year old hypertensive male who developed severe hypertension followed by neurological deterioration in the immediate postoperative period after transurethral resection of prostate. While arterial blood gas and laboratory tests excluded transurethral resection of prostate syndrome or any other metabolic cause, reduction of blood pressure failed to ameliorate the symptoms. A cranial CT done 4hours after the onset of neurological symptoms revealed bilateral gangliocapsular and right thalamic infarcts. Oral aspirin was advised to prevent early recurrent stroke.

Hemodynamic Management of Patients During Endovascular Treatment of Acute Ischemic Stroke Under Conscious Sedation: A Retrospective Cohort Study
Background: Anesthetic modality and hemodynamic management during mechanical thrombectomy (MT) for acute ischemic stroke (AIS) are potential contributors to the success of revascularization. The aims of our study were to review the hemodynamic management by anesthesiologists and clinical outcomes in patients undergoing MT under conscious sedation. Methods: Retrospective cohort study of patients with anterior circulation AIS from January 2012 to March 2016. Primary outcome was hemodynamic intervention, defined as administration of vasoactive drugs to maintain systolic blood pressure (BP) between 140 and 180 mm Hg. ...

Anesthetic Management for Endovascular Treatment of Stroke in Patients With Coronavirus Disease 2019: A Case Series
A significant number of patients with coronavirus disease 2019 develop strokes with large vessel obstructions that may require endovascular treatment for revascularization. Our series focuses on periprocedural issues and the anesthetic management of these patients. We analyzed medical records of 5 patients with positive reverse transcription polymerase chain reaction tests for severe acute respiratory syndrome coronavirus 2 during their hospitalization who underwent endovascular treatment at our hospital between March and mid-June 2020. We found that our patients were different from the typical patients with ischemic strok...

The Outcome of Status Epilepticus and Long-Term Follow-Up
Conclusion: This study highlights the importance of regular care and patient follow-up. Introduction Status epilepticus (SE) is a condition and most extreme form of epilepsy (1), which leads to abnormal and prolonged seizure (at least 5 min). In case SE persists over 30 min, it may have severe long-term consequences (2). Referring to the new classification scheme of SE, there are two operational dimensions of the definition: time point 1 (T1) is associated with abnormally prolonged seizure, when therapy should be initiated, while time point 2 (T2) is related to the time of on-going seizure activity involving a risk...

New Data From Two Large Studies Reinforce Effectiveness of Dual Pathway Inhibition (DPI) with XARELTO ® (rivaroxaban) Plus Aspirin in Patients with Coronary Artery Disease (CAD) and/or Peripheral Artery Disease (PAD)
RARITAN, N.J., May 23, 2022 – Findings from the XARELTO® (rivaroxaban) Phase 3 COMPASS Long-Term Open Label Extension (LTOLE) study and the XARELTO® in Combination with Acetylsalicylic Acid (XATOA) registry have been published in the European Society of Cardiology’s (ESC) European Heart Journal, Cardiovascular Pharmacotherapy. Additionally, the XATOA registry was presented at the American Congress of Cardiology’s 71st Annual Scientific Session (ACC.22).
