Introduction: Women with hypertensive disorders of pregnancy such as HELLP (hemolysis, elevated liver enzyme, low platelet) Syndrome are affected by acute kidney injury during pregnancy (PR-AKI) at higher rates than women without hypertension. Both hypertensive disorders of pregnancy and Acute Kidney Injury (AKI) outside the context of pregnancy have been associated with an increased risk of developing Chronic Kidney Disease (CKD) and cognitive impairment. In our current study, we set out to determine if PR-AKI led to the development of CKD and impaired cognition in the postpartum period and if HELLP syndrome exacerbates the impairments.

Inhibition of PCSK9 Protects against Cerebral Ischemia‒Reperfusion Injury via Attenuating Microcirculatory Dysfunction.

Neurochem Res

November 2024

Department of Neurology, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing, China.

Proprotein convertase substilin/kexin type 9 (PCSK9), a pivotal protein regulating lipid metabolism, has been implicated in promoting microthrombotic formation and inflammatory cascades, thereby contributing to cardiovascular ischemia/reperfusion (I/R) injury. However, its involvement in cerebral I/R injury and its potential role in microcirculation protection remain unexplored. In this investigation, we utilized a middle cerebral artery occlusion/reperfusion (MCAO/R) mouse model to simulate ischemic stroke.

Article Synopsis
  • Type 2 diabetes mellitus (T2DM) leads to smaller pial vessels and lower blood flow velocity before and after a stroke, contributing to poor recovery outcomes.
  • After a stroke, T2DM mice showed persistent deficits in blood flow and increased leukocyte adhesion to blood vessel walls, highlighting chronic inflammation's role in complicating recovery.
  • The study used two-photon microscopy to analyze blood flow dynamics, vessel remodeling, and inflammation in the brain, suggesting that T2DM-induced changes worsen stroke effects.

Article Synopsis
  • * Recent studies suggest that mild hypercapnia—administering CO2—might have protective effects for brain tissue, especially in situations like cardiac arrest, but its impact on ischemic stroke is still not fully understood.
  • * The study found that CO per-conditioning in rat models with middle cerebral artery occlusion reduced infarct size and neurological deficits, preserved blood-brain barrier integrity, and mitigated oxidative stress, indicating potential benefits for ischemic stroke therapy that merit further investigation.

Pediatric CNS-isolated hemophagocytic lymphohistiocytosis with brain hemorrhages: a case report.

BMC Neurol

Division of Pediatric Hematology, Oncology, and Cellular Therapy, Nemours Children's Hospital, Wilmington, Delaware, USA.

Article Synopsis
  • Hemophagocytic lymphohistiocytosis (HLH) is a rare immune disorder, and this case presents a unique instance of it affecting the central nervous system (CNS) in a pediatric patient.
  • A 15-year-old boy exhibited symptoms like ataxia and MRI findings of multiple brain hemorrhages, which led to a confirmed diagnosis of familial CNS-HLH through genetic testing.
  • After failing initial treatments, he underwent stem cell transplantation and showed significant improvement, underlining the importance of considering CNS-HLH in similar cases to avoid delays in diagnosis and treatment.

Article Synopsis
  • Cerebral microbleeds (CMBs) are frequently observed in patients undergoing extracorporeal membrane oxygenation (ECMO), with findings linked to clinical factors.
  • A study involving 138 ECMO patients showed that those with CMBs had significant abnormalities in blood coagulation profiles and lower Glasgow Coma Scale (GCS) scores, suggesting worse neurological outcomes.
  • The research indicates a correlation between CMB burden and coagulation parameters, emphasizing the need for careful monitoring and management of these factors in ECMO patients.

Article Synopsis
  • Primary atopic disorders (PAD) are rare genetic conditions caused by specific gene variants that affect skin and immune function, making diagnosis challenging among common allergic disease cases.
  • Identifying PAD requires recognizing clinical red flags like family history and unusual infections, as conventional lab tests are inadequate for definitive diagnosis.
  • Whole-genome sequencing (WGS) enhances diagnostic efficiency and accuracy, but requires careful interpretation and collaboration among specialists to effectively manage PAD cases.

Article Synopsis
  • - Cardiomyocyte-derived C-type natriuretic peptide (CNP) plays a vital role in heart health by regulating blood flow and heart function, with its effects becoming crucial during myocardial infarction (MI).
  • - Studies on mice showed that those lacking CNP had larger heart damage after MI and worse long-term heart function, while those given CNP treatment showed improvements.
  • - The research suggests that CNP serves as an important protective response from heart cells after an MI, primarily working through a specific receptor (NPR-C), indicating its potential as a new treatment for heart attacks.

This is a case of a young male patient with no known prior risk factors who presented for acute-onset right-sided neurological deficits suspicious for stroke, and magnetic resonance angiography (MRA) identified the development of an occlusion at the level of a basilar artery (BA) fenestration in the setting of right vertebral artery occlusion. The patient was treated with dual-antiplatelet therapy in the hospital and was able to return to work shortly after discharge. The case provides insights into several possibilities for the clinical significance of BA fenestration and its potential causal or contributory relationship with ischaemic stroke of the brainstem.

Article Synopsis
  • Impaired blood flow in the brain due to blood vessel constriction and microthrombi can lead to delayed cerebral ischemia following a subarachnoid hemorrhage (SAH).
  • The overexpression of 12/15-Lipooxygenase (12/15-LOX) is linked to poor early brain injury outcomes, and the study investigates its role in delayed effects after SAH.
  • Results show that inhibiting 12/15-LOX improves brain perfusion and reduces negative outcomes like microvessel constriction and platelet activation, suggesting it could be a key target for treatment after SAH.

Cerebral reperfusion injury in stroke, stemming from interconnected thrombotic and inflammatory signatures, often involves platelet activation, aggregation and its interaction with various immune cells, contributing to microvascular dysfunction. However, the regulatory mechanisms behind this platelet activation and the resulting inflammation are not well understood, complicating the development of effective stroke therapies. Utilizing animal models and platelets from hemorrhagic stroke patients, our research demonstrates that human cerebral dopamine neurotrophic factor (CDNF) acts as an endogenous antagonist, mitigating platelet aggregation and associated neuroinflammation.
