Hippocampus-prefrontal cortex inputs modulate spatial learning and memory in a mouse model of sepsis induced by cecal ligation puncture.

Aims: Sepsis-associated encephalopathy (SAE) often leads to cognitive impairments. However, the pathophysiology of SAE is complex and unclear. Here, we investigated the role of hippocampus (HPC)-prefrontal cortex (PFC) in cognitive dysfunction in sepsis induced by cecal ligation puncture (CLP) in mice.

Association between albumin infusion and septic patients with coronary heart disease: A retrospective study based on medical information mart for intensive care III database.

Coronary heart disease (CHD) is a common comorbidity in intensive care unit (ICU) patients, particularly in the elderly. This particular population may have worse conditions during sepsis, and it presents an overwhelming challenge for clinical practice. Previous studies suggested that patients with CHD have an increased risk of cardiovascular events, and low albumin concentration worsens the prognosis of patients with stable CHD.

SS-31 Improves Cognitive Function in Sepsis-Associated Encephalopathy by Inhibiting the Drp1-NLRP3 Inflammasome Activation.

Neuroinflammation and microglial activation are involved in the pathogenesis of sepsis-associated encephalopathy (SAE). Mitochondrial dynamics emerged as a new player in the regulation of immunological processes. In this study, we aimed at exploring the effects of mitochondrial-targeted antioxidant peptide SS-31 on cognitive function in mice with SAE.

Association of variants in the KIF1A gene with amyotrophic lateral sclerosis.

Background: Amyotrophic lateral sclerosis (ALS) is a devastating progressive neurodegenerative disease that affects neurons in the central nervous system and the spinal cord. As in many other neurodegenerative disorders, the genetic risk factors and pathogenesis of ALS involve dysregulation of cytoskeleton and neuronal transport. Notably, sensory and motor neuron diseases such as hereditary sensory and autonomic neuropathy type 2 (HSAN2) and spastic paraplegia 30 (SPG30) share several causative genes with ALS, as well as having common clinical phenotypes.

Machine learning for early prediction of sepsis-associated acute brain injury.

Background: Sepsis-associated encephalopathy (SAE) is defined as diffuse brain dysfunction associated with sepsis and leads to a high mortality rate. We aimed to develop and validate an optimal machine-learning model based on clinical features for early predicting sepsis-associated acute brain injury.

Methods: We analyzed adult patients with sepsis from the Medical Information Mart for Intensive Care (MIMIC III) clinical database.

[Current satus and future direction of neuromonitoring in patients on extracorporeal membrane oxygenation].

Neurological complications significantly affect the short-and long-term outcomes of patients with extracorporeal membrane oxygenation (ECMO). With the increasing application of ECMO, more and more attention has been paid to the neuromonitoring in ECMO patients. Although many neuromonitoring approaches have already been used clinically, the sensitivity and specificity utilizing one single neuromonitoring assessment to predict brain injury is still insufficient.

Sarcopenia and Mortality Risk of Patients with Sepsis: A Meta-Analysis.

Background: The association between sarcopenia at admission and mortality in patients with sepsis has not been comprehensively evaluated. We performed a meta-analysis to systematically evaluate the above association.

Methods: This meta-analysis included relevant observational studies from Medline, Embase, and Web of Science databases.

PINK1-mediated Drp1 phosphorylation modulates synaptic development and plasticity via promoting mitochondrial fission.

Dynamic change of mitochondrial morphology and distribution along neuronal branches are essential for neural circuitry formation and synaptic efficacy. However, the underlying mechanism remains elusive. We show here that Pink1 knockout (KO) mice display defective dendritic spine maturation, reduced axonal synaptic vesicles, abnormal synaptic connection, and attenuated long-term synaptic potentiation (LTP).

Clinical values of cerebral oxygen saturation monitoring in patients with septic shock.

Objectives: Sepsis associated encephalopathy (SAE) is a common neurological complication of sepsis. Delirium is a common symtom of SAE. The pathophysiology of SAE is still unclear, but several likely mechanisms have been proposed, such as mitochondrial and endothelial dysfunction, neurotransmission disturbances, derangements of calcium homeostasis, cerebral microcirculation dysfunction, and brain hypoperfusion.

[A preliminary study on the classification and prognosis of microcirculation alterations in patients with septic shock].

To explore the correlation between different types of microcirculation alterations and the prognosis in patients with septic shock. This research employed a prospective observational study methodology for selecting subjects with septic shock. Side-stream dark field(SDF) was used to monitor the sublingual microcirculation to determine the total vascular density (TVD), perfused vessel density (PVD), the proportion of perfused vessels (PPV), and the microvascular flow index (MFI), heterogeneity index (HI) indicators.

Lung ultrasound score based on the BLUE-plus protocol is associated with the outcomes and oxygenation indices of intensive care unit patients.

Purpose: The primary objective was to demonstrate the relationship between lung ultrasound (LUS) manifestations and the outcomes of intensive care unit (ICU) patients. The secondary objective was to determine the characteristics of LUS manifestations in different subgroups of ICU patients.

Methods: This prospective multi-center cohort study was conducted in 17 ICUs.

Differences in clinical characteristics between younger and older patients with COVID-19 and their relationship with the length of hospital stay.

Background: The coronavirus disease 2019 (COVID-19) pandemic is currently threatening the health of individuals worldwide. We compared the clinical characteristics between younger patients (aged <60 years) and older patients (aged ≥60 years) with COVID-19, detected the risk factors associated with a prolonged hospital stay, and examined the treatments commonly used with a particular focus on antiviral therapies.

Methods: This retrospective study was conducted at the West Campus, Union Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology (Wuhan, China).
