Nimodipine Reappraised: An Old Drug With a Future.
Abstract Nimodipine is a dihydropyridine calcium channel antagonist that blocks the flux of extracellular calcium through L-type, voltage-gated calcium channels. While nimodipine is FDA-approved for the prevention and treatment of neurological deficits in patients with aneurysmal subarachnoid hemorrhage (aSAH), it affects myriad cell types throughout the body, and thus, likely has more complex mechanisms of action than simple inhibition of cerebral vasoconstriction. Newer understanding of the pathophysiology of delayed ischemic injury after a variety of acute neurologic injuries including aSAH, traumatic brain inj...

Serum calcium channel subunit α2δ-1 concentrations and outcomes in patients with acute spontaneous intracerebral hemorrhage
CONCLUSIONS: Serum α2δ-1 subunit concentrations are intimately correlated with illness severity and are independently associated with poor 90-day outcome, substantializing serum α2δ-1 subunit as a potential prognostic biomarker for ICH.PMID:35007528 | DOI:10.1016/j.cca.2022.01.002

Dihydrolipoic Acid Inhibits Lysosomal Rupture and NLRP3 Through Lysosome-Associated Membrane Protein-1/Calcium/Calmodulin-Dependent Protein Kinase II/TAK1 Pathways After Subarachnoid Hemorrhage in Rat Basic Sciences
Conclusions—DHLA treatment improved neurofunction and alleviated inflammation through the lysosome-associated membrane protein-1/CaMKII/TAK1 pathway in early brain injury after SAH. DHLA may provide a promising treatment to alleviate early brain injury after SAH.

Low Serum Calcium and Magnesium Levels and Rupture of Intracranial Aneurysms Brief Report
Conclusions—In this large case–control study, hypocalcemia and hypomagnesemia at diagnosis were significantly associated with ruptured aneurysms. Impaired hemostasis caused by hypocalcemia and hypomagnesemia may explain this association.

The Role of Serum Calcium Level in Intracerebral Hemorrhage Hematoma Expansion: Is There Any?
AbstractSpontaneous intracerebral hemorrhage (ICH) is a devastating form of stroke, with a high rate of mortality and morbidity. Even with the best current medical or surgical interventions, outcomes remain poor. The location and initial hematoma volume are strong predictors of mortality. Hematoma expansion (HE) is a further marker of poor prognosis that may be at least partly preventable. Several risk factors for HE have been identified, including baseline ICH volume, anticoagulation, and computed tomography angiography spot signs. Recent studies have shown the correlation of serum calcium (Ca++) levels on admission with ...

Summary: International Kidney Cancer Symposium
Conclusions: Ideal ischemia time is 20-25 minutes or less improves short and long term renal function. >25 minutes carried 5 year risk of new onset stage 4 CKD No differences on GFR for cold vs. warm ischemia times Preoperative GFR and the percent of kidney preserved was a better predictor of post op GFR. No ischemia preserves renal function better than warm. Longer cold ischemia times were equivalent to shorter warm ischemia times. Quality and quantity of the remaining kidney is associated with ultimate renal function. Robotics in RCC Surgery Gennady Bratslavsky, MD The opening question ...

Exposure to low-level metalaxyl impacts the cardiac development and function of zebrafish embryos
Publication date: Available online 28 March 2019Source: Journal of Environmental SciencesAuthor(s): Yuqiong Wu, Ying Zhang, Meng Chen, Qihong Yang, Shanshan Zhuang, Liangju Lv, Zhenghong Zuo, Chonggang WangAbstractMetalaxyl is an anilide pesticide that is widely used to control plant diseases caused by Peronosporales species. In order to study the toxic effects, zebrafish embryos were exposed to metalaxyl at nominal concentrations of 5, 50 and 500 ng/L for 72 hr, and the cardiac development and functioning of larvae were observed. The results showed that metalaxyl exposure resulted in increased rates of pericardial ede...

Resveratrol ameliorates brain injury via the TGF- β-mediated ERK signaling pathway in a rat model of cerebral hemorrhage.
In conclusion, these results indicate that resveratrol decreases ischemia/reperfusion-induced neuronal apoptosis by downregulating the TGF-β-mediated ERK pathway in a rat model of cerebral hemorrhage and may serve as a potential agent for the treatment of cerebral hemorrhage.

Review on the Diagnosis and Treatment of Reversible Cerebral Vasoconstriction Syndrome in Children and Adolescents
Semin Neurol DOI: 10.1055/s-0040-1702942Reversible cerebral vasoconstriction syndrome (RCVS) is a clinical–radiologic diagnosis that affects children and adolescents, but it is much more frequently reported in adults. Clinically, patients present with severe and commonly recurrent thunderclap headaches. Typical precipitating triggers include vasoactive substances, serotonergic agents, and the postpartum period. There may be associated neurologic complications at presentation or in the weeks following, such as convexity subarachnoid hemorrhage, stroke, cerebral edema, cervical artery dissection (CeAD), and seizures. Angio...

Current Treatment Options in Cardiovascular Medicine: Update on Reversible Cerebral Vasoconstriction Syndrome
ConclusionRCVS can now be accurately diagnosed using clinical and imaging features available upon presentation. Advances in knowledge about the risk factors, prognosis, and potential harmful effects of certain therapeutic strategies, are expected to optimize the management of this increasingly well recognized syndrome.

Can brain natriuretic peptide, S100b, and interleukin-6 prognosticate the neurological consequences in Egyptian patients presented with supratentorial intracerebral hemorrhage?
Conclusion: Pro-BNP, IL-6, and S100b are greatly associated with the presence of IVH that, in turn, correlated well with poor clinical outcome measures. PMID: 33408945 [PubMed]

Preconditioning Exercise in Rats Attenuates Early Brain Injury Resulting from Subarachnoid Hemorrhage by Reducing Oxidative Stress, Inflammation, and Neuronal Apoptosis
AbstractSubarachnoid hemorrhage (SAH) is a catastrophic form of stroke responsible for significant morbidity and mortality. Oxidative stress, inflammation, and neuronal apoptosis are important in the pathogenesis of early brain injury (EBI) following SAH. Preconditioning exercise confers neuroprotective effects, mitigating EBI; however, the basis for such protection is unknown. We investigated the effects of preconditioning exercise on brain damage and sensorimotor function after SAH. Male rats were assigned to either a sham-operated (Sham) group, exercise (Ex) group, or no-exercise (No-Ex) group. After a 3-week exercise p...

The Current Role of Clevidipine in the Management of Hypertension
AbstractAcute hypertension, which may damage blood vessels, causes irreversible organ damage to the vasculature, central nervous system, kidney, and heart. Clevidipine, the first third-generation calcium channel antagonist approved by the Food and Drug Administration (FDA) in the past 20 years, is an ultra-short-acting calcium channel blocker that inhibits L-type calcium channels with high clearance and low distribution, can be rapidly metabolized into the corresponding inactive acid, and is rapidly hydrolyzed into inactive metabolites by esterase in arterial blood. Clevidipine is the same as nicardipine in that the main p...
