Introduction: Acute intervention (AI) for solid organ injury (SOI) is rare in hemodynamically stable children. Pediatric guidelines recommend admission with follow-up laboratories, even for low-grade injuries.
Methods: Data sets from two large multicenter prospective observational studies were used to analyze a cohort of children (age, <17 years) with grade I to III SOI following blunt abdominal trauma. Children with hollow viscus injuries were excluded. Patients were divided into (a) those with or without other major injuries (OMIs) (traumatic brain injury, hemothorax or pneumothorax, pelvic fracture, urgent orthopedic or neurosurgical operations) and (b) with grade I or II versus grade III injuries. Outcomes included AIs (transfusion, angiography, abdominal operation) and disposition (admission unit and length of stay).
Results: There were 14,232 children enrolled in the two studies, and 791 patients had a SOI (5.6%). After excluding patients with hollow viscus injuries and higher-grade SOIs, 517 patients with a grade I to III SOI were included, and 262 of these had no OMI. Among patients with no OMI, none of 148 patients with grade I or II SOI underwent AI, while only 3 of 114 patients with grade III injuries underwent AI (3 transfusions/1 angioembolization). All three had hemoperitoneum; two of three had an additional organ with a grade II injury. Among grade I and II SOIs with no OMI, 28 (18.9%) of 148 were admitted to an intensive care unit, 110 (74.3%) of 148 to floor, and 7 (4.7%) of 148 discharged home from emergency department; median length of stay 2 days. Among grade III SOIs with no OMI, 38 (33.3%) of 114 were admitted to an intensive care unit and 61.4% to the floor; median length of stay was 4 days. Among 255 patients with a grade I to III SOI and other major organ system injuries, 31 (12.2%) underwent AI.
Conclusion: No patient with a grade I and II SOI and no OMI following blunt abdominal trauma received intervention, suggesting that patients with low-grade SOI without OMIs could be safely observed and discharged from the emergency department.
Level Of Evidence: Therapeutic study, level IV.

Objective: In clinical practice, diagnosing the benignity and malignancy of solid-component-predominant pulmonary nodules is challenging, especially when 3D consolidation-to-tumor ratio (CTR) ≥ 50%, as malignant ones are more invasive. This study aims to develop and validate an AI-driven radiomics prediction model for such nodules to enhance diagnostic accuracy.
Methods: Data of 2,591 pulmonary nodules from five medical centers (Zhengzhou People's Hospital, etc.

Background: Numerous studies have demonstrated limited survival benefits of transarterial chemoembolization (TACE) alone in the treatment of intermediate-stage hepatocellular carcinoma (HCC) beyond up-to-seven criteria. The advent of immunotherapy, particularly immune checkpoint inhibitors (ICIs), has opened new avenues for HCC treatment. However, TACE combined with ICIs has not been investigated for patients with intermediate-stage HCC beyond the up-to-seven criteria.

Nanocarriers have shown significant promise in the diagnosis and treatment of various diseases, utilizing a wide range of biocompatible materials such as metals, inorganic substances, and organic components. Despite diverse design strategies, key physicochemical properties, including hydrodynamic diameter, shape, surface charge, and hydrophilicity/lipophilicity, are crucial for optimizing biodistribution, pharmacokinetics, and therapeutic efficacy. However, these properties are often influenced by drug payload, presenting an ongoing challenge in developing versatile platform technologies for theranostics.

Background: Post-transplant lymphoproliferative disease (PTLD) is a significant complication that can arise following solid organ transplantation or hematopoietic stem cell transplantation. It encompasses a spectrum of lymphoproliferative lesions, ranging from benign reactive hyperplasia to malignant tumors, and is among the most severe complications following liver transplantation in children. It is essential for clinicians to gain a comprehensive understanding of the prevention, clinical manifestations, early diagnosis, and treatment strategies for PTLD in order to reduce mortality rates.

Fever of unknown origin (FUO) can be a common manifestation of multiple disease processes like infections, hematological & solid organ malignancies, autoimmune disorders, and autoinflammatory diseases. Endocrine causes of FUO are rare but should be considered in differential diagnosis. We present a case of a 35-year-old female with prolonged on-and-off fever and intermittent vomiting for nine months, where extensive workups for chronic infections, malignancy, and autoimmune conditions initially yielded no definitive diagnosis.
