Cognitive dysfunction caused by diabetes has become a serious global medical issue. Diabetic kidney disease (DKD) exacerbates cognitive dysfunction in patients, although the precise mechanism behind this remains unclear. Here, we conducted an investigation using RNA sequencing data from the Gene Expression Omnibus (GEO) database.

Oxidative stress and inflammation seem to be the main factors responsible for cognitive impairment in sepsis. Genistein (GEN) is claimed to exert many beneficial effects on health, however, its possible effects on brain sepsis remains unclear. Here, we assess the influence and underling mechanisms of GEN on cognitive impairments in cecal ligation and puncture (CLP)-induced septic model.

Background: Sepsis is defined as organ dysfunction caused by an uncontrolled response to infection and is followed by a high incidence of cognitive dysfunction, which can severely affect patients' quality of life. Previous studies have suggested that electroacupuncture (EA) is protective against sepsis-associated cognitive dysfunction and that pyroptosis plays a vital role in cognitive function. The aim of this study was to investigate the effect of EA on cognition and neuronal pyroptosis in a mouse model of sepsis.

Objective: Fungal infections are common in pediatric intensive care units (PICUs), but the monitoring methods are limited. This study analyzed the differences in clinical features, diagnosis, and treatment between PICU patients with and without fungal infection.

Methods: This retrospective study analyzed PICU patients at the Maternal and Child Health Hospital of Hubei Province diagnosed with severe pneumonia between January 2015 and January 2020.

Article Synopsis
  • The study aimed to determine if measuring the optic nerve sheath diameter (ONSD) with ultrasound can predict brain injury in cases of sepsis-associated encephalopathy (SAE) using a rabbit model.
  • A total of 48 male rabbits were induced with sepsis, and various biomarkers (like MPO, NSE, and S100B) were tracked alongside changes in ONSD over time.
  • Results showed that ONSD increased more significantly in SAE-affected rabbits compared to controls and had a strong correlation with the injury biomarkers, indicating that monitoring ONSD could be a reliable predictor of brain injury in SAE.

Background: Propofol acts as an intravenous anesthetic cure which is widely used as a therapy for the craniocerebral injury that comprised surgical anesthesia as well as the sedation done in the intensive care units. Propofol is one of the most commonly used and efficient anesthetics where the painful effects are followed by an injection of propofol. In many cases, patients experience pain followed by anxiety, boredom, fear, and even myocardial ischemia.

Article Synopsis
  • Osteosarcoma is a prevalent bone cancer primarily affecting children and adolescents, and this study examines how gas anesthetics impact the behavior of osteosarcoma cells, particularly focusing on invasion, metastasis, and response to chemotherapy.
  • Isoflurane and sevoflurane significantly inhibit osteosarcoma cell migration and proliferation at clinically relevant doses, while desflurane is less effective; all anesthetics enhance the effects of chemotherapeutic drugs.
  • The research concludes that gas anesthetics influence the survival, movement, growth, and sensitivity to chemotherapy in osteosarcoma cells, potentially by affecting specific cellular pathways like PI3K/AKT and IGF-1.

Background: To analyze the application of neurally adjusted ventilatory assist in ventilator weaning of infants.

Methods: A total of 25 infants (15 boys and 10 girls) who were mechanically ventilated by PICU in Hubei Maternal and Child Health Hospital were selected as the study subjects. After the improvement of the basic disease, regular spontaneous breathing, and the withdrawal of the ventilator, all the children obtained the electrical activity of the diaphragm (EAdi) signal.

Objective: To investigate the diagnostic value of plasma miRNA-497, cardiac troponin I (cTnI), fatty acid binding protein 3 (FABP3), glycogen phosphorylase isoenzyme BB (GPBB) in pediatric sepsis complicated with myocardial injury.

Methods: From August 2018 to February 2020, 82 children with sepsis admitted to our hospital and 50 health children who came for physical examination (defined as control group) were enrolled in this study. Children with sepsis and myocardial injury were enrolled in the combined group (n=35), and those without myocardial injury were enrolled in the sepsis group (n=47).

Invasive pulmonary aspergillosis (IPA) is a serious infectious disease with high mortality. However, the rapid diagnosis of IPA remains difficult since the microbiological evidence is difficult to obtain or time-consuming. Thus, we attempted to rapidly diagnose two pediatric cases with respiratory failure due to IPA via bronchoalveolar lavage fluid with Calcofluor White fluorescence staining, which has rarely been used before.

Background: Mycobacterium bovis could infect patients with immunodeficiency or immunosuppressive conditions via Bacillus Calmette-Guérin (BCG) vaccination. Tuberculosis-related hemophagocytic syndrome (HPS) is reported, but not HPS caused by Mycobacterium bovis in children.

Case Presentation: A 4-month Chinese boy presented fever and cough.

Background: The intra- and postoperative effects of dexmedetomidine are not completely consistent and midazolam/fentanyl is most widely used in peripheral surgeries. The objectives of the study were to evaluate the sedative, analgesic, hemodynamic, anti-inflammatory, and antioxidant effects of dexmedetomidine against midazolam in patients undergoing peripheral surgeries with mild traumatic brain injuries.

Methods: Medical records of patients who underwent peripheral surgeries with mild traumatic brain injury were included in the analysis.
