RESUMO
BACKGROUND: The incidence of perioperative stroke following spinal surgery, including ischemic and hemorrhagic stroke, has not been fully investigated in the Chinese population. Whether specific spinal or emergency/elective procedures are associated with perioperative stroke remains controversial. This study aimed to investigate the incidence of perioperative stroke, health economic burden, clinical outcomes, and associated risk factors. METHOD: A retrospective cohort study using an electronic hospital information system database was conducted from Jan 1, 2015, to Jan 1, 2021, in a tertiary hospital in China. Patients aged ≥18 years who had undergone spinal surgery were included in the study. We recorded patient demographics, comorbidities, and health economics data. Clinical outcomes included perioperative stroke during hospitalization and associated risk factors. The patients' operative data, anesthetic data, and clinical manifestations were recorded. RESULT: A total of 17,408 patients who had undergone spinal surgery were included in this study. Twelve patients had perioperative stroke, including seven ischemic stroke (58.3%) and five hemorrhagic stroke (41.7%). The incidence of perioperative stroke was 0.07% (12/17,408). In total, 12 stroke patients underwent spinal fusion. Patients with perioperative stroke were associated with longer hospital stay (38.33 days vs. 9.78 days, p < 0.001) and higher hospital expenses (RMB 175,642 vs. RMB 81,114, p < 0.001). On discharge, 50% of perioperative patients had severe outcomes. The average onset time of perioperative stroke was 1.3 days after surgery. Stroke history (OR 146.046, 95% CI: 28.102-759.006, p < 0.001) and hyperlipidemia (OR 4.490, 95% CI: 1.182-17.060, p = 0.027) were associated with perioperative stroke. CONCLUSION: The incidence of perioperative stroke of spinal surgery in a tertiary hospital in China was 0.07%, with a high proportion of hemorrhagic stroke. Perioperative stroke patients experienced a heavy financial burden and severe outcomes. A previous stroke history and hyperlipidemia were associated with perioperative stroke.

BACKGROUND: Intracranial hemorrhage after spinal surgery is a rare and devastating complication. AIM: To investigate the economic burden, clinical characteristics, risk factors, and mechanisms of intracranial hemorrhage after spinal surgery. METHODS: A retrospective cohort study was conducted from January 1, 2015, to December 31, 2022. Patients aged ≥ 18 years, who had undergone spinal surgery were included. Intracranial hemorrhage patients were selected after spinal surgery during hospitalization. Based on the type of spinal surgery, patients with intracranial hemorrhage were randomly matched in a 1:5 ratio with control patients without intracranial hemorrhage. The patients' pre-, intra-, and post-operative data and clinical manifestations were recorded. RESULTS: A total of 24472 patients underwent spinal surgery. Six patients (3 males and 3 females, average age 71.3 years) developed intracranial hemorrhage after posterior spinal fusion procedures, with an incidence of 0.025% (6/24472). The prevailing type of intracranial hemorrhage was cerebellar hemorrhage. Two patients had a poor clinical outcome. Based on the type of surgery, 30 control patients were randomly matched in 1:5 ratio. The intracranial hemorrhage group showed significant differences compared with the control group with regard to age (71.33 ± 7.45 years vs 58.39 ± 8.07 years, P = 0.001), previous history of cerebrovascular disease (50% vs 6.7%, P = 0.024), spinal dura mater injury (50% vs 3.3%, P = 0.010), hospital expenses (RMB 242119.1 ± 87610.0 vs RMB 96290.7 ± 32029.9, P = 0.009), and discharge activity daily living score (40.00 ± 25.88 vs 75.40 ± 18.29, P = 0.019). CONCLUSION: The incidence of intracranial hemorrhage after spinal surgery was extremely low, with poor clinical outcomes. Patient age, previous stroke history, and dura mater damage were possible risk factors. It is suggested that spinal dura mater injury should be avoided during surgery in high-risk patients.
RESUMO
OBJECTIVES: Stroke is the leading cause of death and adult disability in China, following a rise in incidence over the last few decades. We aimed to explore the geographic variations in hospital mortality and endovascular therapy (EVT) use among ischaemic stroke (IS) patients in China, and investigate the associated potential risk factors. DESIGN: Observational cross-sectional study of patients hospitalised for stroke. SETTING: Hospital discharge data for 1267 tertiary hospitals between 1 January 2015 and 31 December 2015 were derived from the Nationwide Hospital Discharge Database operated by the National Health Commission of China. PARTICIPANTS: 1 826 332 patients aged ≥18 years, hospitalised following stroke. OUTCOME MEASURES: In-hospital mortality and EVT use. RESULTS: The nationwide hospital mortality rate of IS patients was 0.88% (95% CI 0.86% to 0.90%); there was a significantly greater risk of mortality in the Northeast (OR 2.37; 95% CI 2.23 to 2.52), West (1.65; 1.54 to 1.78), South (1.25; 1.17 to 1.33) and North (1.29; 1.20 to 1.39) than in the East. Tertiary B hospitals (OR 1.05; 95% CI 1.00 to 1.09), patients admitted from emergency departments and older patients were associated with higher hospital mortality. The national EVT use rate was 0.45% (95% CI 0.44% to 0.46%). Compared with in East China, EVT use was significantly lower in the Northeast (OR 0.22; 95% CI 0.20 to 0.24) and West (0.64; 0.58 to 0.71), though not the North (1.23; 1.14 to 1.33). Tertiary A hospitals (OR 2.62; 95% CI 2.43 to 2.83), male patients and patients admitted from emergency departments were also associated with higher EVT use rates. CONCLUSIONS: There were substantial disparities in mortality and EVT use for hospitalised patients with IS among China's tertiary hospitals, linked with both geographic and hospital characteristics. More targeted intervention at regional and hospital levels is needed for providing effective health technologies and eventually improving post-stroke outcomes.

Amyloid ß and alpha 1-antichymotrypsin (ACT) play an important role in the pathogenesis of sporadic Alzheimer's disease (AD). The present study was to investigate whether a combination of plasma biomarkers and clinical data would discriminate AD from vascular dementia, other neurodegenerative dementia and non-demented controls. The study included 112 patients with AD, 85 patients with vascular dementia, 30 patients with other neurodegenerative dementia and 116 age-matched, non-demented controls. Although ACT, Aß42 and the ratio of Aß42/Aß40 had significant differences between AD, vascular dementia, other neurodegenerative dementia and non-demented controls (P<0.001), none of them reached the sensitivity and specificity required for AD biomarkers. The combination of biomarkers and clinical data had higher discriminating power than either alone. Our results indicated that plasma biomarkers of ACT and the ratio of Aß42/Aß40 could discriminate AD from non-demented controls, vascular dementia, or other neurodegenerative dementias with higher diagnostic accuracy than clinical data and that if plasma biomarkers were combined with clinical data, the discriminating power was enhanced.
