Background : The treatment strategy of early nutritional support after cardiac surgery has gradually been adopted. However, there are no scientific guidelines for the timing and specific programs of early nutritional support. Methods: A retrospective, single-center analysis (2021-2023) was carried out including elderly patients who were admitted for valvular heart disease and received open-heart valve replacement surgery. ⋯ The EN group also seemed to have shorter hospital stays and lower hospitalization expenses ( P < 0.001). In the comparison of postoperative gastrointestinal complications, fewer patients experienced diarrhea ( P = 0.021) and abdominal distension ( P = 0.033) in the EN group compared with the TN group. Conclusion: The optimal nutritional support strategy could effectively improve the clinical outcome of high-risk patients with valvular heart disease.

Severe respiratory syncytial virus (RSV) pneumonia is a leading cause of hospitalization and morbidity in infants and young children. Early identification of severe RSV pneumonia is crucial for timely and effective treatment by pediatricians. Currently, no prediction model exists for identifying severe RSV pneumonia in children. ⋯ This study identified specific biomarkers and developed a diagnostic model for severe RSV pneumonia in children. These findings provide a robust foundation for early identification and treatment of severe RSV pneumonia, offering new insights into its pathogenesis and improving pediatric care.

The neuronal biomarker NSE correlates with the volume of lung contusion in polytraumatized patients.
Severe injuries caused by accidents, like traumatic brain injury (TBI) or thoracic trauma (TT) continue to be the leading cause of death in younger people with relevant socio-economic impact. Fast and targeted diagnostics is essential for further therapy decisions and prognosis. The following study investigates NSE as a potential biomarker for lung injury after blunt TT. ⋯ A significant NSE release after isolated thoracic trauma peaks on the day of admission. The extent of lung contusion volume (defined as alveolar parenchymal density) correlates with NSE serum concentration. Thus, NSE has predictive value for the extent of pulmonary contusion. However, according to these data, NSE seems to have no diagnostic value as a TBI biomarker in concomitant TT.

Background: Sepsis accounts for substantial morbidity and mortality motivating investigators to continue the search for pathways and molecules driving the pathogenesis of the disease. The current study examined if the novel C-type lectin receptor (CLR), Clec2d, plays a significant role in the pathogenesis of sepsis. Methods: Clec2d knockout (KO) mice were fully backcrossed onto the C57/BL6 background. ⋯ These values were also lower in the KO mice compared to the WT in CLP, but the breath rate and body temperature were increased in the KO pneumonia mice. Conclusion: The C-type lectin receptor Clec2d plays a complicated role in the pathogenesis of sepsis, which varies with source of infection as demonstrated in the models used to study the disease. These data highlight the heterogeneity of the responses to sepsis and provide further evidence that a single common pathway driving sepsis organ injury and death likely does not exist.

Background: Histidine-rich glycoprotein (HRG), a potential prognostic factor in sepsis, lacks clarity regarding its relevance in septic-induced shock, disseminated intravascular coagulation (DIC), and acute respiratory distress syndrome (ARDS) pathogenesis. This study investigated the association between HRG concentrations and these critical conditions. Methods: Blood samples were collected from 53 critically ill patients on days 1, 3, 5, and 7 after ICU admission at the Kyushu University Hospital. ⋯ On day 5, an HRG level with a cutoff of 25.5 μg/mL showed a sensitivity of 0.77 and a specificity of 0.75, indicating significantly lower survival rates (log-rank test, P < 0.05). Conclusion: HRG presents a potential intervention for critically ill sepsis patients, providing a novel strategy to enhance outcomes. Further research is needed to explore the therapeutic potential of HRG in sepsis management.
