Machine learning validation of a simple prediction model for the correlation between advanced age and clinical outcomes in patients with aneurysmal subarachnoid hemorrhage.

Adverse effects of advanced age and poor initial neurological status on outcomes of patients with aneurysmal subarachnoid hemorrhage (SAH) have been documented. While a predictive model of the non-linear correlation between advanced age and clinical outcome has been reported, no previous model has been validated. Therefore, we created a prediction model of the non-linear correlation between advanced age and clinical outcome by machine learning and validated it using a separate cohort.

Risk factors of short-term poor functional outcomes and long-term durability of ruptured large or giant intracranial aneurysms.

Objective: Aneurysmal subarachnoid hemorrhage (SAH) is associated with high morbidity and mortality rates. In particular, functional outcomes of SAH caused by large or giant (≥ 10 mm) ruptured intracranial aneurysms are worsened by high procedure-related complication rates. However, studies describing the risk factors for poor functional outcomes specific to ruptured large/giant aneurysms are sparse.

Cilostazol Alleviates Delayed Cerebral Ischemia After Subarachnoid Hemorrhage by Attenuating Microcirculatory Dysfunction.

Cilostazol, a phosphodiesterase 3 (PDE3) inhibitor that exerts antiplatelet effects, has therapeutic potential for delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH). However, its mechanism of action remains unclear. We hypothesized that cilostazol alleviates DCI by improving cerebral microcirculatory dysfunction, which is a component of early brain injury.

Interplay of co-cultured chimeric adipose and gingival tissues exacerbates inflammatory dysfunction relevant to periodontal and metabolic conditions.

Adipose tissue dysfunction is a key feature of metabolic syndrome, which increases the risk of periodontitis, an inflammatory disease induced by bacteria that affects the gingiva and other components of periodontal tissue. Recent studies indicate that molecules from inflamed periodontal tissue contribute to adipose tissue dysfunction. However, the cellular mechanisms and interactions between adipose tissue and gingiva driving the progression of metabolic and periodontal conditions remain unclear.

Long-term postoperative prognosis and associated risk factors of chronic subdural hematoma in the elderly.

Surgical treatment for chronic subdural hematoma（CSDH）has contributed to good outcome. However, several recent studies have revealed that surgical outcomes for elderly patients were not decisively good. In this study, prognosis of CSDH patients in elderly were analyzed.
