Acute hydrocephalus and delayed cerebral infarction after aneurysmal subarachnoid hemorrhage

Association of Hemoglobin Decrement During Hospitalization with Prognosis of Aneurysmal Subarachnoid Hemorrhage and Mediation Effects of Cerebral Infarction and Pneumonia

Background

Hemoglobin decrement is a common complication after aneurysmal subarachnoid hemorrhage (aSAH) and is associated with poor outcome. However, the mediating variables on the causal pathway between hemoglobin decrement and poor outcome in aSAH are not clear.

Methods

This is a single-center retrospective observational study containing all consecutive patients with aSAH admitted to our hospital between January 1, 2019, and June 30, 2022. Hemoglobin decrement was defined as the hemoglobin at admission minus the minimum hemoglobin during hospitalization. Calculation of cutoff value using ROC curve Youden index. The main exposure of interest was a hemoglobin decrement greater than the cutoff value. The primary outcome was poor outcome at 3 months (mRS 4-6).

Results

A total of 480 patients with aSAH were included in the study, 414 (71.1%) had a favorable and 66 (28.9%) had a poor outcome at 3 months. The cut-off value for calculating the degree of hemoglobin decrease using the ROC curve was 12.5 g/l. Hemoglobin decrement greater than the cutoff value was significantly associated with pneumonia (OR 3.12; 95% CI 1.78-5.57; p < 0.001), cerebral infarction (OR 3.06; 95% CI 1.80-5.30; p < 0.001), and poor prognosis (OR 2.88; 95% CI 1.44-5.92; p = 0.003) at 3 months. The mediation effect was significant for both pneumonia and cerebral infarction, with the average causal mediation effect (ACME) were 0.04 (95% CI 0.02-0.08; p < 0.05) and 0.05 (95% CI 0.02-0.08; p < 0.001), respectively.

Conclusion

Hemoglobin decrement during hospitalization was significantly associated with poor prognosis after aSAH, and the increased risk of cerebral infarction and pneumonia might mediate this effect. Avoiding hemoglobin decrement greater than 12.5g/l may improve the prognosis of patients with aSAH.

The value of modified hijdra score in patients with aneurysmal subarachnoid hemorrhage

Background

The complexity of calculating the Hijdra score has limited its clinical utility in aiding the diagnosis of intracranial ruptured aneurysms.

Objective

This study aimed to investigate the diagnostic and prognostic value of the modified Hijdra score in patients with aneurysmal subarachnoid hemorrhage (aSAH).

Methods

Data from 773 patients with subarachnoid hemorrhage (SAH) at the First People's Hospital of Lianyungang from January 2018 to June 2023 were collected. The modified Hijdra scoring method simplifies the assessment of 10 basal cisterns/cisterns fissures compared to the traditional scoring method, with scores ranging from 0 to 2 for each item, and assigns specific scores to hematomas larger than 1 cm in diameter. The data were divided into an evaluation group (n = 641) and a validation group (n = 132). In the evaluation group, the performance of the modified Hijdra score in diagnosis and prognostic prediction was assessed, while the diagnostic and prognostic prediction efficacy of the modified Hijdra method was evaluated using the validation set.

Results

Among the 641 patients in the evaluation group,550 (85. 8%) were diagnosed with intracranial aneurysms. The modified Hijdra score demonstrated an AUC of 0. 894 for aneurysm diagnosis, with a sensitivity of 98. 0% and a specificity of 64. 8% at a CutOff value of 7. 5. The diagnostic efficacy of the modified Hijdra score was 93. 24%, with a negative predictive value of 84. 29%, while the Hijdra score 's diagnostic efficacy was 85. 34% with a negative predictive value of 48. 89%. The AUC of the modified Hijdra score for predicting prognosis in patients with aneurysms was 0. 824, with a sensitivity of 84. 3% and a specificity of 70. 0% at a CutOff value of 16. 5. In CTA-negative patients, the modified Hijdra score was significantly higher (P < 0. 0001) in patients with aneurysmal SAH (15. 48 ± 3. 93) compared to those with non-aneurysmal SAH (6. 31 ± 4. 52).

Conclusions

The modified Hijdra score is a valuable tool for assisting in the diagnosis and prognosis prediction of aneurysmal subarachnoid hemorrhage.

Impacts of evidence-based nursing combined with enteral nutrition on nutritional status and quality of life in acute cerebral infarction patients: A randomized controlled trial

OBJECTIVE

To explore the impacts of evidence-based nursing (EBN) combined with enteral nutrition (EN) on nutritional status as well as quality of life in acute cerebral infarction (ACI) patients.

METHODS

In this randomized controlled cluster trial, 80 ACI patients admitted to our hospital from January 2021 to December 2022 were selected and randomly separated into study group (SG) and control group (CG), with 40 patients in each group. Patients in CG received routine nursing, and patients in the SG received EBN combined with EN. The neurological function, limb movement ability, nutritional status, anxiety and depression, incidence of complications and quality of life between two groups were compared.

RESULTS

After intervention, the NIHSS score in the SG was lower than that in the CG (CG = 5.62 ± 0.56, SG = 3.27 ± 0.33. p < .001). The FMA score in the SG was higher compared with the CG (CG = 52.58 ± 5.32, SG = 68.85 ± 6.87. p < .001). The Hb level, TP level and ALB level in the SG were higher relative to the CG (p < .001). The Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores in the SG were lower in comparison with the CG (SAS score: CG = 42.32 ± 4.25, SG = 36.28 ± 3.64; SDS score: CG = 48.27 ± 4.85, SG = 40.06 ± 4.05. p < .001). The incidence of complications in SG was lower than that in CG. Finally, we found that SF-36 scores in the SG in all dimensions were higher than those in the CG (Physiological function: CG = 70.23 ± 7.05, SG = 82.71 ± 8.26. Role function: CG = 66.28 ± 6.64, SG73.39 ± 7.36. Physical pain: CG = 70.67 ± 7.06, SG = 82.69 ± 8.29. General health: CG = 58.74 ± 5.86, SG66.62 ± 6.65. Mental health: CG = 53.68 ± 5.37, SG = 62.39 ± 6.31. Energy: CG = 60.75 ± 6.08, SG = 67.87 ± 6.78. Social function: CG = 76.25 ± 7.25, SG = 85.78 ± 8.59. Emotional function: CG = 61.23 ± 6.15, SG = 75.74 ± 7.56. p < .001).

CONCLUSION

EBN combined with EN can improve the nutritional status and the quality of life in ACI patients compared with the traditional routine nursing, and is suggested as a valuable strategy for clinical management of ACI.

Predicting the need for cerebrospinal fluid shunt implantation after spontaneous intracerebral hemorrhage: a challenging task

Objectives

The development of persistent hydrocephalus in patients after spontaneous intracerebral hemorrhage (ICH) is still poorly understood, and many variables predicting the need for a cerebrospinal fluid (CSF)-shunt have been described in the literature with varying results. The aim of this study is to find predictive factors for shunt dependency.

Methods

We performed a retrospective, single-center study of 99 neurosurgically treated patients with spontaneous ICH. Variables, including age, Glasgow Coma Scale (GCS), intraventricular hemorrhage (IVH), location of hemorrhage, acute hydrocephalus, and volumetric analysis of IVH, ICH, and intraventricular CSF were compared between patients with and without CSF-shunt implantation. Furthermore, receiver operating characteristics (ROC) for ICH, IVH, and intraventricular CSF volume parameters were calculated.

Results

CSF-shunt implantation was performed significantly more often in patients after thalamic (p = 0.03) and cerebellar ICH (p = 0.04). Moreover, a lower ratio between the total hemorrhage volume and intraventricular CSF volume (p = 0.007), a higher IVH distribution in the third ventricle, and an acute hydrocephalus (p < 0.001) with an increased intraventricular CSF volume (p < 0.001) were associated with shunt dependency. Our ROC model demonstrated a sensitivity of 82% and a specificity of 65% to predict the necessity for a shunt at a cutoff value of 1.9 with an AUC of 0.835.

Conclusion

Volumetric analysis of ICH, IVH, and intraventricular CSF may improve the prediction of CSF shunt implantation in patients with spontaneous ICH.

Risk factors and predictive models of poor prognosis and delayed cerebral ischemia in aneurysmal subarachnoid hemorrhage complicated with hydrocephalus

Objective

To evaluate the correlation of serum biological markers and related scales to the occurrence of delayed cerebral ischemia and clinical prognosis in patients with aneurysmal subarachnoid hemorrhage (aSAH) complicated with acute hydrocephalus before admission.

Methods

The clinical data of 227 patients with pre-admission aSAH complicated with acute hydrocephalus admitted to Henan Provincial People's Hospital from April 2017 to December 2020 were retrospectively analyzed. Patients were grouped according to the presence or absence of delayed cerebral ischemia (DCI) after surgery and the prognosis at 6 months after discharge. Univariate and multivariable logistic regression analysis were performed to analyze the relationship between serum biological indicators combined with aneurysm related clinical score scale and the occurrence and prognosis of delayed cerebral ischemia. ROC curves and nomogram were drawn.

Results

Multivariable Logistic regression analysis showed that high Hunt-Hess grade and surgical clipping were independent risk factors for postoperative DCI (P < 0.05). Older age, higher Hunt-Hess grade, higher CRP and neutrophil levels were independent risk factors for poor prognosis at 6 months after surgery (P < 0.05). ROC curve analysis showed that the area under the curve (AUC) of Hunt-Hess grade and surgical method for predicting DCI in patients with aSAH combined with hydrocephalus after surgery were 0.665 and 0.593. The combined AUC of Hunt-Hess grade and surgical method was 0.685, the sensitivity was 64.9%, and the specificity was 64.7%. The AUC of CRP, neutrophil, age and Hunt-Hess grade for predicting poor prognosis in patients with aSAH combined with hydrocephalus at 6 months after surgery were 0.804, 0.735, 0.596, 0.757, respectively. The combined AUC of CRP, neutrophil, age, Hunt-Hess grade was 0.879, the sensitivity was 79%, and the specificity was 84.5%. According to the correction curve, the predicted probability of the nomogram is basically consistent with the actual probability.

Conclusion

Hunt-Hess grade and surgical method are independent predictors of postoperative DCI in patients with aSAH complicated with hydrocephalus. “CRP,” “neutrophil,” “age” and “Hunt-Hess grade” at admission are independent predictors of clinical prognosis in patients with aSAH complicated with hydrocephalus. The combination of the above indicators has high predictive value.
