[Comparison of clinical features of septic shock in children with hematological malignancies versus children without malignant tumors].

Objective: To investigate the clinical features of septic shock in children with hematological malignancies compared with those without malignant tumor in the pediatric intensive care unit (PICU). Methods: This retrospective study enrolled children with septic shock at the PICU of Capital Institute of Pediatrics' Children's Hospital from June 2015 to July 2022. According to the presence of hematological malignancies, patients were divided into the hematological malignancies group and without malignant tumor group. Clinical data were compared between the two groups, and logistic regression analysis was used to identify related factors for mortality. Results: A total of 164 children (97 males and 67 females) with a median age of 3.6 (interquartile range 0.8, 7.8) years were enrolled, including 75 (45.7%) patients with hematological malignancies and 89 (54.3%) patients without malignant tumors. Patients in the hematological malignancies group were older [6.0(3.6, 9.4) years vs 1.2 (0.4, 4.3) years, P<0.001] and more experienced hospital-acquired infections [48.0%(36/75) vs 21.3%(19/89),P=0.001], compared with patients without malignant tumors. Surgical emergencies were more frequent in patients without malignant tumors (32.6% vs 14.7%, P=0.013). Patients with hematological malignancies mainly had blood stream infections (58.7%), with Gram-negative bacilli (46.7%), meanwhile, patients without malignant tumors more experienced Gram-positive cocci infections (22.5%) of the respiratory system (40.4%) or digestive system (28.1%). There were significant differences regarding the infection sites (P<0.001) and pathogens (P=0.001). The types of antibacterial agents (P<0.001) and the frequency of noradrenaline (P=0.013) used in patients with hematological malignancies were significantly higher than those without malignant tumors. Patients with hematological malignancies had a higher incidence of multiple organ dysfunction (MODS) [100.0%(75/75) vs 80.9%(72/89), P<0.001] and higher 28-day mortality [34.8%(23/66) vs 19.0%(15/79),P=0.048]. Multivariate logistic regression analysis showed that Pediatric Critical Illness Score (PCIS) was an independent factor for death (odds ratio, OR=1.387, 95%CI: 1.161-1.657, P<0.001) in patients with hematological malignancies, and PCIS (OR=1.419, 95%CI: 1.140-1.767, P=0.002) and the 6-hour lactate clearance rate (OR=65.857, 95%CI: 2.953-1 468.638, P=0.008) were independent factors for death in patients without malignant tumors. Conclusions: Children with hematological malignancies were older, more frequently experienced bloodstream infections, and had a higher incidence of MODS and higher 28-day mortality. PCIS is related to poor prognosis of septic shock in children.

[Clinical characteristics and prognosis analysis of 17 cases of SMARCA4-deficient chest tumors].

Objective: To analyze the clinical characteristics and prognosis of 17 patients with pathologically confirmed SMARCA4-deficient chest tumors. Methods: Seventeen patients with SMARCA4-deficient thoracic tumors diagnosed by pathology in the Affiliated Hospital of Jining Medical University from September 2021 to January 2023 were collected through Results Query System of Pathology Department, and the patients' general conditions, clinical symptoms, tumor markers, imaging features, treatment and regression were retrospectively analyzed, and literature review was performed. Results: A total of 17 patients were included in this study. Their clinical characteristics were characterized as follows: male/female=16/1, age 42-74 years, mean (64.0±5.7)years. Only 1 female had no clear smoking history, and 16 males had a smoking history, of whom 1 had 5 smoking pack-years, and the remaining 15 case had a smoking history of 20-100 smoking pack-years, with a mean of (68.5±44.5) smoking pack-years. Clinical symptoms were mainly cough and sputum, followed by chest tightness, hemoptysis and chest pain. Tumor markers CYFRA19-9 was elevated in 9 cases (3.79-16.61 ng/ml), CEA was elevated in 8 cases (5.37-295.93 ng/ml), and NSE was elevated in 6 cases (17.18-70.37 ng/ml). Imaging manifestations were intrapulmonary or mediastinal mass shadows, and the tumor involved the mediastinum in 9 cases, the upper lobe of the right lung in 6 cases, the upper lobe of the left lung in 5 cases, the lower lobe of the right lung in 3 cases, the lower lobe of the left lung in 3 cases; cervical or supraclavicular lymph node metastasis in 8 cases, pleural metastasis in 4 cases, hepatic metastasis in 3 cases, cerebral metastasis in 3 cases, bone metastasis in 2 cases, and subcutaneous metastasis in 1 case. Combining immuno-histochemistry and pathology, there were 6 cases of SMARCA4-deficient NSCLC and 11 cases of SMARCA4-deficient undifferentiated tumor. Eight patients were treated with platinum-contained chemotherapy agents, four of which were combined with immune checkpoint inhibitors, and one was treated with enzatinib; only one of the 9 patients achieved partial remission after treatment, and the remaining eight had progression of the tumors on chest CT after treatment. Five patients abandoned the treatment, and died in 6-month of follow-up. Three patients underwent surgery for resection, and there was no significant progression in the three patients in the 6 months of follow-up. Conclusions: Clinically, middle-aged and elderly men with a history of heavy smoking should be given high priority, especially in patients whose imaging mostly showed intrapulmonary, especially in upper lobes, and/or mediastinal masses, rapid lesion progression, and early distant metastasis, and who should be alerted to the possibility of SMARCA4-deficient thoracic tumors. Late clinical stage is a high risk factor for poor overall patient survival, and platinum-containing chemotherapy agents combined with immune checkpoint inhibitor therapy may be effective, and early surgery may improve patient prognosis.

Prognostic and immune roles of UROC1 in human cancers: from mechanism exploration of NAFLD and HCC to pan-cancer analysis.

OBJECTIVE: Both non-alcoholic fatty liver disease (NAFLD) and hepatocellular carcinoma (HCC) are prevalent diseases worldwide. This study aimed to explore the underlying mechanisms of NAFLD and HCC and identify new therapeutic targets for human cancers. MATERIALS AND METHODS: NAFLD and HCC gene expression profiles were obtained from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) and weighted gene co-expression network analysis (WGCNA) were utilized to identify co-expressed genes associated with NAFLD and HCC. Public databases were consulted to find common targets of NAFLD and HCC. Enrichment analysis and CIBERSORT techniques were employed to analyze the pathways enriched with DEGs and the attributes of infiltrating immune cells. Furthermore, the expression data of UROC1 and clinical information of patients were acquired from The Cancer Genome Atlas (TCGA) database. Finally, the expression of the UROC1 was validated by immunohistochemistry (IHC). RESULTS: Through a comprehensive bioinformatics analysis, eight hub genes (CCL2, CCR2, IL6, CSF3R, ATL2, SESN3, UROC1, FIGNL1) were identified. Enrichment analysis indicated that inflammatory and immune response may be common features between NAFLD and HCC. CIBER-SORT analysis revealed an imbalance of plasma cells and macrophages in NAFLD and HCC. Pan-cancer analysis demonstrated that UROC1 expression was related to clinical outcomes and tumor immunity in various cancers. Moreover, a strong correlation was exhibited between UROC1 expression and crucial elements, including tumor mutation burden (TMB), microsatellite instability (MSI), multiple immune checkpoints (ICP), and tumor microenvironment (TME). Importantly, an adverse clinical prognosis of HCC was linked to decreased UROC1 expression, which was consistent with IHC results. CONCLUSIONS: We identified eight hub genes (CCL2, CCR2, IL6, CSF3R, ATL2, SESN3, UROC1, FIGNL1), which may become early diagnostic and therapeutic targets for NAFLD and HCC. The pan-cancer analysis of UROC1 provides new evidence for its broad application prospects in the field of HCC and other cancers.

Study on the correlation between dietary structure and sleep in patients with insomnia disorder.

OBJECTIVE: Insomnia disorder (ID) is a persistent difficulty sleeping, often accompanied by anxiety and depression, which seriously reduces a person's quality of life. Dietary changes in insomnia patients have been a concern. To explore the rationality of diet in patients with ID and its correlation with insomnia in ID patients. PATIENTS AND METHODS: This study included 216 patients diagnosed with ID and 197 individuals as the healthy control (HC) group who attended the neurology outpatient clinic or sleep clinic at Henan Provincial People's Hospital between September 2018 and November 2019. Through the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Hamilton Anxiety Scale (HAMA), and Hamilton Depression Scale (HAMD), sleep and mental conditions were assessed in the ID and HC groups. The dietary intake structure of both groups was observed using the food frequency table. Meanwhile, the relationship between dietary intake and sleep quality was analyzed based on the logistics regression. RESULTS: Individuals in the ID group had significantly higher age, weight, and body mass index compared to the HC group (p<0.01). Individuals within the ID category demonstrated a heightened daily consumption of carbohydrates, grains, tubers, and legumes relative to the healthy control group. In contrast, the intake levels of vegetables, fruits, and nuts were diminished compared to the HC group, with this difference being statistically significant (p<0.01). A positive correlation was observed between the daily consumption of grains, tubers, and legumes and PSQI scores. Conversely, a negative association was found between daily consumption of vegetables and fruits. CONCLUSIONS: ID patients exhibit an elevated intake of carbohydrates, whereas the consumption of vegetables, fruits, and nuts is deficient in comparison to the healthy cohort, implying that a distorted dietary structure might be a contributing factor to ID onset. Sensible and scientific dietary guidance is of considerable significance in preventing the onset of ID and facilitating its management. However, the derived conclusions warrant further extensive research.

[Accurate localization and successful treatment of 23 cases of migrating pharynx and cervical esophageal foreign bodies].

Objective: To explore clinical features, diagnosis, localization, and therapeutic strategy of migratory pharyngeal and cervical esophageal foreign bodies. Methods: A total 23 cases of pharyngeal and cervical esophageal migratory foreign bodies were admitted between January 2015 and December 2021. There were 14 females and 9 males with the age ranged from 35 to 82 (55.0±12.7)years. In all the cases, esophageal CT was taken to confirm the esophageal foreign body. Multiplanar reconstruction (MPR) was performed to locate the foreign body from the horizontal, coronal and sagittal dimensions as well as the corrected reconstructed MPR. According to the location of the foreign body, appropriate surgical method was selected.The symptoms, complications, types of foreign body, positioning, surgical methods, and relevant information were recorded.Data were analyzed using the descriptive method and SPSS 25.0 software. Results: The clinical symptoms of 23 migrating esophageal foreign bodies included pharyngodynia (20/23), foreign body sensation (6/23), hoarsenss (1/23), difficulty in turning neck(1/23), difficulty in opening mouth (1/23), fever (7/23), poor appetite (1/23), and abdominal pain (1/23). The foreign bodies included 19 fish bones, 2 wires, 1 embroidery needle and 1 chicken bone. There were 9 cases (39.1%) of foreign bodies located in extraluminal cervical esophagus, 2 cases (8.7%) of foreign bodies located in the muscular layer of the cervical esophagus and 12 cases (52.2%) of foreign bodies located in pharynx. Twenty-one cases of foreign bodies were removed by cervical lateral incision, in which 11 were removed by cervical lateral incision directly, 10 by the second lateral cervical incision after the foreign bodies were accurately located by MPR and/or corrected MPR, 1 foreign body was removed by incision of the pharyngeal mucosa under suspension laryngoscope, 1 foreign body was removed by tracheoscopy. Compared with patients with intraluminal foreign bodies (n=308) treated in the same period, intake of fishbone [19 (19/23) vs. 133 (82.6% (43.2%, 133/308), OR=7.31] and first visit was more than 24 hours [20(87.0%, 20/23) vs. 77(25.0%, 77/308),OR=17.2] were the significant risk factors of migratory esophageal foreign bodies. Conclusions: MPR and the corrected MPR can accurately locate the migrating pharyngeal and cervical esophageal foreign bodies, by providing more intuitive imaging evidence for doctors, which provide imaging basis for formulation of surgical programs. Foreign bodies in pharyngeal and cervical esophagus need to be treated as soon as possible, otherwise they are easy to migrate, leading lead to serious complications.
