AI Article Synopsis
- The study investigates the link between Val279Phe SNPs in the PAF-AH gene and intracranial hemorrhage in preterm infants.
- A case-control design compared 58 preterm infants with hemorrhage and 65 without, using PCR to analyze genetic variations.
- Results showed significant differences in genotype and allele frequencies between groups, suggesting that specific SNPs may increase the risk of intracranial hemorrhage.
Article Abstract
Objective: To explore whether Val279Phe single nucleotide polymorphisms (SNPs) in the 9th exon of platelet-activating factor acetylhydrolase (PAF-AH) are associated with intracranial hemorrhage in preterm infants.
Methods: A case-control study was performed. Polymerase chain reaction (PCR) was used to test genotype and allele frequencies of the 9th exon Val279Phe SNPs of PAF-AH in 58 preterm infants with intracranial hemorrhage (hemorrhage group) and 65 preterm infants without intracranial hemorrhage (control group).
Results: There were significant differences in genotype frequency of Val279Phe SNPs in the 9th exon of PAF-AH between the hemorrhage and control groups (P<0.05). Frequency of normal genotype in the hemorrhage group (63.8%) was significantly lower than in the control group (81.5%). In contrast, frequency of heterozygous genotype (34.5%) in the hemorrhage group was significantly higher than in control group (16.9%). There were also significant differences in allele frequency of Val279Phe SNPs in the 9th exon of PAF-AH between the two groups (P<0.05). T allele frequency in the hemorrhage group (19.0%) was significantly higher than in the control group (10.0%).
Conclusions: Val279Phe SNPs in the 9th exon of PAF-AH may be associated with intracranial hemorrhage in preterm infants.

Introduction: Preclinical studies have shown that oxygen therapy can improve ischaemic brain tissue oxygen tension, reduce reperfusion injury after revascularisation, promote neuroregeneration and inhibit inflammatory responses potentially exerting a beneficial effect after endovascular treatment (EVT) in patients with acute ischaemic stroke (AIS). However, the optimal fraction of inspired oxygen (FiO) during EVT under general anaesthesia is currently unknown. Therefore, we are conducting a randomised controlled trial (RCT) to evaluate the impact of high-concentration oxygen vs low-concentration normobaric oxygen on early neurological function after EVT.

Ventriculoperitoneal shunt (VPS) insertion is a neurosurgical procedure done routinely for managing hydrocephalus. However, the technique of shunt insertion remains controversial. In this study, we retrospectively compared the accuracy of shunt placement using ultrasound (US) guidance to freehand insertion.

It is estimated that two billion people worldwide are infected with hepatitis B. In such cases, patients exposed to the virus may experience HBV-reactivation(HBVr), which is usually due to immunosuppression. It is not anticipated that spontaneous-HBVr will occur in the absence of immunosuppression in resolved HBV.

Background: There are limited therapeutic options in cases of failed reperfusion (modified thrombolysis in cerebral infarction [mTICI] score < 2b) after stent-retriever and/or aspiration based endovascular treatment (EVT) for acute ischemic stroke. Despite the absence of data supporting its use, rescue therapy (balloon angioplasty and/or stent implantation) is often utilized in such cases. Studies are limited to large vessel occlusions, while the outcomes and complications after rescue therapy in medium/distal vessel occlusions (MDVOs) have not been reported.

Rationale: The Chemical Optimization of Cerebral Embolectomy (CHOICE) trial suggested that the administration of intra-arterial alteplase after successful endovascular thrombectomy (EVT) may improve neurological outcomes in patients with acute ischemic stroke due to large vessel occlusion (AIS-LVO) in the anterior circulation. However, the use of adjunctive intra-arterial alteplase following successful EVT in acute posterior circulation stroke remains unexplored.
Aims: This study aims to investigate the efficacy and safety of intra-arterial alteplase after successful EVT for AIS-LVO in the posterior circulation.
