Summary: The study found that obstructive sleep apnea (OSA) is associated with the risk of intracerebral hemorrhage (ICH). Cases with OSA were more likely to be male and have hypertension, heart disease, hyperlipidemia, and higher body mass index compared to those without OSA. Logistic regression analysis showed that OSA is a risk factor for ICH.

Summary: Recently, there has been increased recognition of iatrogenic cerebral amyloid angiopathy (iCAA) cases globally. This case study examines the clinicoradiological features of a probable iCAA case in Australia, with extensive history documentation and MRI data spanning two decades. The study highlights the aggressive course and early disease manifestations of iCAA, providing insights for the more commonly seen sporadic cases.

Summary: This study investigated the cognitive function of patients with cerebral amyloid angiopathy (CAA) with and without intracerebral hemorrhage (ICH) and found that cognitive impairment is common in CAA, indicating the potential role of underlying neurodegeneration, possibly related to co-existing Alzheimer's disease pathology.

Summary: Cerebral amyloid angiopathy (CAA) is a significant cerebral small vessel disease that is associated with brain haemorrhage and cognitive change. While the common form affects individuals in mid- to later life, rare early-onset forms are increasingly recognized and may be caused by genetic or iatrogenic factors. This review provides an overview of the causes of early-onset CAA and proposes a structured approach for investigation and management, aiming to raise awareness among healthcare professionals.

Summary: Hemorrhagic stroke is the deadliest form of stroke and includes the subtypes of intracerebral hemorrhage and subarachnoid hemorrhage. Inflammatory immune responses play a crucial role in the pathophysiology of these types of stroke, both affecting tissue recovery and injury. Understanding these processes can lead to the development of effective therapeutic strategies.

Summary: This study provides an in-depth analysis of the role of hypertension in adult MMA patients and finds that hypertension does not increase the risk of postoperative complications or negative angiographic development after revascularization procedures. It may actually improve bypass patency and filling following the surgery.

Summary: This study aimed to investigate the risk of future cerebrovascular events in patients with ischemic stroke (IS) or transient ischemic attack (TIA) and cortical superficial siderosis (cSS), as well as the benefits and safety of antithrombotic drugs for secondary prevention. The study found that cSS was associated with an increased risk of stroke, and the risk of IS was higher than that of intracranial hemorrhage (ICrH) in patients receiving antiplatelet or anticoagulant treatment alone, while the risk of ICrH was higher than that of IS in patients receiving both treatments. Therefore, the study suggests that using antiplatelet or anticoagulant drugs alone is safe in patients with cSS, but combined antithrombotic therapy might be hazardous.

Summary: The study longitudinally evaluated families with dominantly inherited Alzheimer disease to investigate the risk associated with cerebral microhemorrhages (CMHs) or microbleeds. Eight percent of carriers developed CMHs, associated with increased clinical, cognitive, and motor impairments, highlighting the significant relationship between CMHs and the development of hemorrhagic amyloid-related imaging abnormality (ARIA-H).

Summary: Moyamoya disease (MMD) and moyamoya syndrome (MMS) are progressive vascular pathologies unique to the cerebrovasculature, with distinct features and pathophysiological characteristics. While MMD shares some molecular pathways with arterial stenosis diseases like atherosclerosis and fibromuscular dysplasia (FMD), there are still central questions regarding the underlying pathogenesis of these diseases.

Summary: This study found that cerebral venous reflux (CVR) is more closely associated with cerebral amyloid angiopathy (CAA) than hypertensive microangiopathy in intracerebral hemorrhage (ICH) survivors. The results suggest that venous drainage dysfunction potentially plays a role in CAA and cerebral amyloid deposition.

Summary: Traumatic brain injury (TBI) impairs cellular energy demand, compromising neuronal function and plasticity. This study demonstrates that the mitochondrial activator humanin (HN) can counteract the reduction in mitochondrial bioenergetics caused by TBI, restore memory function and synaptic protein levels, and suppress inflammation and astrocyte proliferation. HN plays an integral role in normalizing fundamental aspects of TBI pathology.

Summary: Colorectal cancer often requires adjuvant therapies to reduce tumor burden, and the efficacy of these therapies is significantly influenced by reactive oxygen species (ROS). ROS-mediated colorectal cancer adjuvant therapies involve multiple mechanisms, and preliminary clinical trials have shown the potential of ROS-manipulating therapy in enhancing treatment outcomes.

Summary: Pancreatic adenocarcinoma (PAAD) is a common digestive malignant tumor with limited treatment options. This study demonstrates that TGM2 may serve as a marker for treatment and prognosis in pancreatic cancer patients. Co-treatment of low dose cisplatin (DDP) and the TGM2 inhibitor GK921 effectively inhibits PAAD cell viability and proliferation in vitro and in vivo, by inhibiting epithelial-to-mesenchymal transition (EMT) induced by TGM2 and enhancing cell cycle arrest and apoptosis caused by DDP. These findings suggest that the combination of GK921 and DDP holds promise as a treatment for PAAD patients.

Summary: Depression is a common neuropsychiatric comorbidity in Alzheimer's disease (AD) and other Tauopathies. Selective serotonin reuptake inhibitor (SSRI) treatment, such as Citalopram, not only has anti-depressive and anxiolytic effects, but also helps improve neurogenesis, reduce amyloid burden & Tau pathologies, and neuroinflammation in AD. In this study, Citalopram was found to reduce pathologically pTau level, increase synaptic gene expression and cytoskeletal structure, as well as improve cell survival, mitochondrial respiration, and mitochondrial morphology in cells expressing mutant APP and Tau. These findings suggest that Citalopram could be a promising therapeutic drug for treating depression and AD.

Summary: Bone is a self-healing organ that undergoes continuous regeneration through the cooperation of osteoclasts and osteoblasts. This study used ATAC-seq and RNA-Seq techniques to investigate the chromatin accessibility and transcriptomic landscape of osteoblast differentiation and mineralization. The results showed that global chromatin accessibility was extensively improved during osteoblastogenesis. Additionally, several transcription factors including MEF2A, PRRX1, Shox2, and HOXB13 were found to modulate the promoter accessibility of target genes during osteoblast differentiation.

Summary: Congenital sucrase-isomaltase deficiency (CSID) is an autosomal recessive disorder caused by variants in the SI gene. A frameshift mutation called c.273_274delAG (p.Gly92Leufs*8) has been identified in CSID patients in Greenlandic population, which leads to loss of digestive function of SI. Surprisingly, the truncated mutant can still be located on the cell surface and interacts with wild type SI, negatively affecting its enzymatic function. Furthermore, heterozygote carriers of this mutation may also exhibit CSID symptoms.
