BACKGROUND
COVID-19 has been spreading worldwide at hitherto unknown speed, and the treatment of neuro-oncology patients without COVID-19 has been greatly affected.
Methods
To compare the medical records and surgical results of surgical patients before and after the pandemic. We collected a total of 80 patients form April 2020 to May 2020 after pandemic and from April 2019 to May 2019 before pandemic. The patient's demographics, past medical history, comorbidities, imaging, pathology, laboratory teat, and Karnofsky Performance Score (KPS) were analyzed.
Results
The most common presenting symptom was intracranial hypertension and neurological deficit. Hypertension and diabetes were the most common comorbid diseases. The pre-operation KPS were 83.21 ± 15.60, 80 ± 14.77, 78.57 ± 12.83 and 74.14 ± 12.72, respectively. The post-operation KPS were 94.64 ± 8.65, 95.45 ± 6.56, 91.43 ± 10.82 and 84.21 ± 22.55, respectively. The tumor volume was larger and the midline shift distance was greater after the pandemic than before. For pathological grade, meningiomas were mostly grade I, while gliomas were mainly grade III and IV.
Conclusion
Although affected by the COVID-19 pandemic, patients with glioma should be operated as soon as possible to obtain better surgical results, however, for patients with meningiomas, their operation can be postponed slightly when the patients are tolerable.
Background
Although multiple signaling cascades and molecules contributing to the pathophysiological process have been studied, the treatments for stroke against present targets have not acquired significant clinical progress. Although CARD3 (caspase activation and recruitment domain 3) protein is an important factor involved in regulating immunity, inflammation, lipid metabolism, and apoptosis, its role in cerebral stroke is currently unknown.
Methods and Results
Using a mouse model of ischemia‐reperfusion (I‐R) injury based on transient blockage of the middle cerebral artery, we have found that CARD3 expression is upregulated in a time‐dependent manner during I‐R injury. Further animal study revealed that, relative to control mice, CARD3‐knockout mice exhibited decreased inflammatory response and neuronal apoptosis, with reduced infarct volume and lower neuropathological scores. In contrast, neuron‐specific CARD3‐overexpressing transgenic (CARD3‐TG) mice exhibited increased I‐R induced injury compared with controls. Mechanistically, we also found that the activation of TAK1 (transforming growth factor‐β–activated kinase 1) was enhanced in CARD3‐TG mice. Furthermore, the increased inflammation and apoptosis seen in injured CARD3‐TG brains were reversed by intravenous administration of the TAK1 inhibitor 5Z‐7‐oxozeaenol.
Conclusions
These results indicate that CARD3 promotes I‐R injury via activation of TAK1, which not only reveals a novel regulatory axis of I‐R induced brain injury but also provides a new potential therapeutic approach for I‐R injury.
Rationale:Extracranial–intracranial saphenous vein bypass (EC-IC SVB) remains indispensable for treating giant cavernous aneurysms. We report an unusual case of a giant cavernous aneurysm in an elderly patient treated with EC-IC SVB in a hybrid operating room. Immediately following proximal ligation of the internal carotid artery (ICA), she suffered an acute intraoperative encephalocele.Patient concerns:A 71-year-old woman had suffered from severe headache and double vision for 4 months.Diagnoses:The woman was diagnosed with a right giant cavernous aneurysm.Interventions:She was treated with an EC-IC SVB with therapeutic ICA occlusion in the first biplane hybrid operating room in China. Just after proximal ligation of the ICA, she developed an acute encephalocele, and immediately underwent decompressive craniectomy. During the surgery she underwent 3 angiographic explorations.Outcomes:After surgery, the aneurysm disappeared, and the graft was patent. Postoperative computed tomography and computed tomography angiography indicated a cranial defect and graft patency.Lessons:Although a hybrid operating room could improve the patency of grafts, the timing of ICA ligation for giant cavernous aneurysm via EC-IC bypass deserves further discussion. Second-stage ICA occlusion could offer an alternative for elderly patients requiring such treatment. In addition, cranial flap removal could prevent further neurologic deficits in a case of acute intraoperative encephalocele.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
