BackgroundThe present study aimed to evaluate the short-term efficacy and safety of drug-eluting beads transarterial chemoembolization (DEB-TACE) with CalliSpheres Beads loaded with doxorubicin (DOX) in the treatment of Chinese patients with hepatocellular carcinoma (HCC) compared to conventional TACE (cTACE).MethodsA total of 54 patients with HCC treated by TACE from June 2016 to February 2017 were retrospectively analyzed. These included 24 cases in the DEB-TACE group and 30 cases in the cTACE group. The clinical efficacy, tumor recurrence rate, and complications were compared between the two groups. Furthermore, liver function tests and alpha-feto protein levels were compared between the two groups before and at 1 week and 1 month after interventional treatment.ResultsThere were no significant differences in baseline characteristics (p > 0.05). Tumor response rates and disease control rates in the DEB-TACE group were significantly higher than those in the cTACE group at 3 and 6 months after treatment (p < 0.05). Recurrence rates at 6 months were significantly higher for cTACE compared to DEB-TACE (43.3 vs. 16.7%; p = 0.036). At 1 month, the AFP level in the DEB-TACE group was significantly lower than that in the cTACE group (p = 0.008). At the end of follow-up, four cases in the DEB-TACE group and two cases in the cTACE group were treated with salvage surgery after downstaging the disease. Liver function of both groups improved at 1 month. However, alanine aminotransferase, aspartate aminotransferase, and total bilirubin levels in the DEB-TACE group were better than those in the cTACE group (p < 0.05). The incidence of DOX-related complications in the DEB-TACE group was significantly lower than in the cTACE group (p < 0.05).ConclusionThe short-term efficacy of DEB-TACE is better, and the complication rates are lower compared to cTACE in the treatment of Chinese patients with HCC. However, long-term clinical efficacy and survival benefit should be analyzed in future studies.
Background: Recently, the World Health Organization has declared the coronavirus disease 2019 (COVID-19) outbreak a public health emergency of international concern. So far, however, limited data are available for children. Therefore, we aimed to investigate the clinical and chest CT imaging characteristics of COVID-19 in preschool children.Methods: From January 26, 2020 to February 20, 2020, the clinical and initial chest CT imaging data of eight preschool children with laboratory-confirmed COVID-19 from two hospitals were retrospectively collected. The chest CT imaging characteristics, including the distribution, shape, and density of lesions, and the pleural effusion, pleural changes, and enlarged lymph nodes were evaluated. Results: Two cases (25%) were classified as mild type, and they showed no obvious abnormal CT findings or minimal pleural thickening on the right side. Five cases (62.5%) were classified as moderate type. Among these patients, one case showed consolidation located in the subpleural region of the right upper lobe, with thickening in the adjacent pleura; one case showed multiple consolidation and ground-glass opacities with blurry margins; one case displayed bronchial pneumonia-like changes in the left upper lobe; and two cases displayed asthmatic bronchitis-like changes. One case (12.5%) was classified as critical type and showed bronchial pneumonia-like changes in the bilateral lungs, presenting blurred and messy bilateral lung markings and multiple patchy shadows scattered along the lung markings with blurry margins.Conclusions: The chest CT findings of COVID-19 in preschool children are atypical and various. Accurate diagnosis requires a comprehensive evaluation of epidemiological, clinical, laboratory and CT imaging data.
Patterns of change in whole‐brain functional networks remain poorly understood in patients with end‐stage renal disease (ESRD) undergoing hemodialysis (HD). We conducted a prospective research to investigate the topological properties of whole‐brain functional networks in those patients using a graph‐based network analysis. Resting‐state functional magnetic resonance imaging was performed on 51 ESRD patients (25 HD and 26 nondialysis patients) and 36 healthy controls (HCs). We compared the topological properties of brain functional networks among the three groups, and analyzed the relationships between those significant parameters and clinical variables in ESRD patients. Progressively disrupted global topological organizations were observed from nondialysis patients to HD patients compared with HCs (all p < 0.05 after Bonferroni correction). HD patients, relative to HCs, showed significantly decreased nodal centralities in the left temporal pole: superior temporal gyrus, bilateral median cingulate and paracingulate gyri, bilateral hippocampus, bilateral parahippocampal gyrus, and bilateral amygdala, and showed increased nodal centralities in the orbital part of the bilateral middle frontal gyrus, left cuneus, and left superior occipital gyrus (all p < 0.05 after Bonferroni correction). Furthermore, nodal centralities in the bilateral hippocampus were significantly decreased in HD patients compared with nondialysis patients (p < 0.05 after Bonferroni correction). Dialysis duration negatively correlated with global efficiency in ESRD patients undergoing HD (r = −0.676, FDR q = 0.004). This study indicates that ESRD patients exhibit disruptions in brain functional networks, which are more severe in HD patients, and these alterations are correlated with cognitive performance and clinical markers.

Background: Neuroimaging studies have demonstrated disrupted brain functional networks in major depression disorder (MDD); however, alterations to whole-brain networks specifically associated with adolescent MDD remain poorly understood. Purpose: To investigate the topological architecture of intrinsic brain functional networks in drug-naïve, first-episode adolescent MDD patients using graph theoretical analysis. Study type: Prospective. Subjects: In all, 109 adolescent MDD patients and 70 healthy control subjects. Field Strength/Sequences: 3.0T; gradient-echo echo-planar imaging sequence. Assessment: After the construction of whole-brain functional networks by thresholding partial correlation matrices of 90 brain regions, we calculated the topological properties (eg, small-world, efficiency, and nodal centrality) using graph theoretical analysis. Statistical Tests: A chi-squared test was used to compare the gender-ratio difference, and a two-sample t-test was used in the comparison of age. We compared network measures between the two groups using nonparametric permutation tests. Exploratory partial correlation analyses were used to determine the relationships between the topological metrics showing significant between-group differences and the clinical variables for adolescent MDD patients. Results: Small-world architecture in brain functional networks was identified for both the MDD and control groups. However, depressed adolescents exhibited lower characteristic path length, normalized characteristic path length and clustering coefficient, and higher global efficiency than controls (false discovery rate [FDR] q < 0.05). Compared with controls, depressed adolescents exhibited increased nodal centralities in the default mode regions, including the right anterior cingulate and paracingulate gyri, left posterior cingulate gyrus, right superior frontal gyrus (medial part), bilateral hippocampus, and bilateral parahippocampal gyrus, and decreased nodal centralities in the orbitofrontal, temporal, and occipital regions (FDR q < 0.05). Data Conclusion: This study indicated that drug-naïve, first-episode adolescent MDD patients exhibit disruptions in wholebrain functional networks. Level of Evidence: 1 Technical Efficacy Stage: 2
