AI Article Synopsis
- Inflammation after intracerebral hemorrhage (ICH) can lead to secondary brain injury, and ACEIs/ARBs may help manage this issue, but their effectiveness in clinical settings is still unclear.
- A study analyzed data from 635 ICH patients with hypertension, comparing those on ACEIs/ARBs to those not on these medications; results showed lower mortality and incidence of pneumonia in the ACEIs/ARBs group.
- Although there was no significant difference in overall favorable outcomes between groups, patients on ACEIs/ARBs had less perihematomal edema on days 3 and 7 post-ICH.
Article Abstract
Background: Inflammation plays an essential role in secondary brain injury after intracerebral hemorrhage (ICH). Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) have been suggested to suppress neuroinflammation after central nervous system (CNS) damage in animal models. However, the role of ACEIs and ARBs in ICH patients with hypertension remains unresolved in clinic. The aim of the present study is to evaluate the effect of ACEIs/ARBs on ICH patients with hypertension using a retrospective, single-center data analysis.
Methods: ICH patients diagnosed by computerized tomographic (CT) at Southwest Hospital, Third Military Medical University were included in the present research from January 2015 to December 2019. According to the medical history for the usage of antihypertensive drugs, patients were assigned into either ACEIs/ARBs group or non-ACEIs/ARBs group. Demographics, clinical baseline, radiological documents and treatments were collected and these data were statistically analyzed between the two groups.
Results: A total of 635 ICH patients with hypertension were included and allocated into 2 groups according to the usage of antihypertensive drugs: 281 in the ACEIs/ARBs group and 354 in the non-ACEIs/ARBs group. The results presented that the 3-months mortality and prevalence of ICH-associated pneumonia were lower in ACEIs/ARBs group than that in non-ACEIs/ARBs group (5.0% vs 11.9%, p=0.002; 58.4% vs 66.7%, p=0.031). While, there was no significant difference in favorable outcome (40.2% vs 33.9%, p=0.101) between the two groups. Furthermore, patients in ACEIs/ARBs group exhibited significantly less perihematomal edema volume on days 3 (23.5 ± 14.4 versus 28.7 ± 20.1 mL, p=0.045) and 7 (21.0 ± 13.7 versus 25.7 ± 17.6 mL, p=0.044), compared to that in non- ACEIs/ARBs group.
Conclusion: The usage of ACEIs/ARBs helps decrease mortality, perihematomal edema volume, and prevalence of ICH-associated pneumonia in ICH patients with hypertension.

Non-Invasive Brain Stimulation to Improve Functional Recovery and Predict Outcome After Intracerebral Hemorrhage: A Narrative Review.

Intracerebral hemorrhage (ICH) is a leading cause of stroke-related mortality and long-term disability, with initial ICH volume, age, location of the hemorrhage, and clinical severity being key predictors of outcome. While clinical scores incorporating these elements are validated and exhibit good inter-rater reliability, their accuracy in predicting long-term recovery remains suboptimal. Non-invasive brain stimulation (NIBS) has emerged as a potential adjunct for improving both prognostication and functional recovery in ICH survivors.

This study aimed to evaluate the effect of sample size on the development of a three-dimensional convolutional neural network (3DCNN) model for predicting the binary classification of three types of intracranial hemorrhage (ICH): intraparenchymal, subarachnoid, and subdural (IPH, SAH, SDH, respectively). During the training, we compiled all images of each brain computed tomography scan into a single 3D image, which was then fed into the model to classify the presence of ICH. We divided the non-hemorrhage quantities into 20, 30, 40, 50, 100, and 150 and the ICH quantities into 20, 30, 40, and 50.

Background: Mucopolysaccharidosis (MPS) are a group of lysosomal storage diseases with substantial unmet medical needs-for both patients and caregivers. Approved therapies are limited, and the perception of investigative ones remains enigmatic.
Method: Using an innovative survey concept based on the discrete choice experiment method (DEC) with neuronopathic and non-neuronopathic patient scenarios, we aimed to evaluate how parents of children with MPS perceive different approved and innovative therapies.

Background: Left ventricular assist devices (LVADs) are used as definitive therapy or as a bridge to heart transplant in patients with advanced heart failure. Thromboembolic complications such as acute ischemic stroke (AIS) are common among patients with LVAD support. This study aims to evaluate the current evidence on the efficacy and safety of mechanical thrombectomy (MT) in patients with AIS due to large vessel occlusions (LVO) and LVAD-support.
