Aim: Paediatric evidence about the clinical implications of enlarged abdominal lymph nodes (EALN) is not univocal. The main purpose of our study was to evaluate the clinical significance and the morphological evolution of enlarged abdominal nodes in children with recurrent abdominal pain.
Methods: All children with recurrent abdominal pain diagnosed with EALN were enrolled at the involved centres between September 2017 and June 2018. Number, size, localisation, shape and architecture of nodes were accurately recorded along with clinical and laboratory data at enrolment and after three and six months.
Results: A total of 38 children were enrolled. After the six-month study period, 58% of them had lymph nodes reduced in size, 13% had unchanged lymph nodes, and 29% had lymph nodes increased in size. Overall, we observed a gradual, albeit slight reduction in the average size of enlarged nodes over the six-month period. The extent of size changes was not correlated with any clinical parameter.
Conclusion: Our data suggest that EALN are a non-specific finding, which is not worth a change in the diagnostic and therapeutic management of children with abdominal pain.

To evaluate the clinical value of multi-slice spiral CT in preoperative TNN staging and postoperative recurrence and metastasis of colon carcinoma, and to provide evidence for the reliability of CT in the diagnosis of colon carcinoma METHODS: 89 patients with colon carcinoma diagnosed pathologically in our hospital from July 2020 to April 2023 were selected retrospectively. The preoperative TNN staging and postoperative recurrence and metastasis were monitored by 64 row 128 layer spiral CT. The diagnostic coincidence rate, TNM staging coincidence rate and postoperative recurrent TNM staging accuracy were evaluated according to the pathological diagnosis RESULTS: The diagnostic coincidence rate of multi-slice spiral CT was 97.

Protective antibodies against HIV-1 require unusually high levels of somatic mutations introduced in germinal centers (GCs). To achieve this, a sequential vaccination approach was proposed. Using HIV-1 antibody knockin mice with fate-mapping genes, we examined if antigen affinity affects the outcome of B cell recall responses.

The use of dual-tracer contrast agents in clinical applications, such as sentinel lymph node (SLN) identification, offers significant advantages including enhanced accuracy, sensitivity, as well as comprehensive and multimodal visualization. In the current clinical practice, SLNs are typically marked prior to surgical resection by multiple and sequential injections of two tracers, the radioactive tracer and methylene blue (MB) dye. This imposes physical and psychological burden on patients and medical staff.

Background: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive lethal malignancy with limited options for treatment and a 5-year survival rate of 11% in the United States. As for other types of tumors, such as colorectal cancer, aberrant lipid synthesis and reprogrammed lipid metabolism have been suggested to be associated with PDAC development and progression.
Aim: To identify the possible involvement of lipid metabolism in PDAC by analyzing in tumoral and non-tumoral tissues the expression level of the most relevant genes involved in the long-chain fatty acid (FA) import into cell.

Objectives: We present a case series of patients with granulomatous myocarditis presenting as atrial arrhythmias accompanied by lymphadenopathy.
Background: Atrial myocarditis (AM) may be the cause of atrial fibrillation (AF) in patients without risk factors.
Methods: Patients with atrial fibrillation without risk factors underwent 18F-Fluorodeoxyglucose positron emission tomography (18F-FDG-PET).
