This systematic review was conducted to compare the effectiveness of sutureless closure and conventional surgery as the primary repair for TAPVC. Systematic search was performed in June 2021 on 12 databases. All studies comparing sutureless and conventional surgery for TAPVC were included. The primary endpoints were early mortality, overall mortality, postoperative pulmonary venous stenosis (PVS), and reoperation. Meta-analysis of two-arm studies was performed with several sensitivity and subgroup analyses. Six retrospective studies with 767 patients were included in meta-analyses. Sutureless closure significantly reduced the risk of early mortality, overall mortality, postoperative PVS, and reoperation by 53%, 45%, 77%, and 67% compared to conventional technique, respectively. No heterogeneity was found and presence of publication bias was non-significant. The results were consistent in all sensitivity analyses. Subgroup analyses revealed that sutureless closure was superior to conventional technique in patients with and without preoperative pulmonary venous obstruction, and neonates and non-neonates. Sutureless closure is better than conventional closure as the primary surgery for TAPVC patients. We advocate using sutureless closure for patients with TAPVC. Future large-scale observational studies or clinical trials are required to confirm our findings.Congenital heart disease (CHD) is a common birth defect in the United States. CHD infants are more likely to have smaller head circumference and neurodevelopmental delays; however, the cause is unknown. Altered cerebrovascular hemodynamics may contribute to neurologic abnormalities, such as smaller head circumference, thus we created a novel Cerebrovascular Stability Index (CSI), as a surrogate for cerebral autoregulation. We hypothesized that CHD infants would have an association between CSI and head circumference. We performed a prospective, longitudinal study in CHD infants and healthy controls. We measured CSI and head circumference at 4 time points (newborn, 3, 6, 9 months). We calculated CSI by subtracting the average 2-min sitting from supine cerebral oxygenation (rcSO2) over three consecutive tilts (0-90°), then averaged the change score for each age. Linear regressions quantified the relationship between CSI and head circumference. We performed 177 assessments in total (80 healthy controls, 97 CHD infants). The average head circumference was smaller in CHD infants (39.2 cm) compared to healthy controls (41.6 cm) (p  less then  0.001) and head circumference increased by 0.27 cm as CSI improved in the sample (p = 0.04) overall when combining all time points. Similarly, head circumference increased by 0.32 cm as CSI improved among CHD infants (p = 0.04). We found CSI significantly associated with head circumference in our sample overall and CHD infants alone, which suggests that impaired CSI may affect brain size in CHD infants. Future studies are needed to better understand the mechanism of interaction between CSI and brain growth.
To investigate the utility of radiomics features of diffusion-weighted magnetic resonance imaging (DW-MRI) to differentiate fat-poor angiomyolipoma (fpAML) from clear cell renal cell carcinoma (ccRCC).

This multi-institutional study included two cohorts with pathologically confirmed renal tumors 65 patients with ccRCC and 18 with fpAML in the model development cohort, and 17 with ccRCC and 13 with fpAML in the external validation cohort. All patients underwent magnetic resonance imaging (MRI) including DW-MRI. Radiomics analysis was used to extract 39 imaging features from the apparent diffusion coefficient (ADC) map. The radiomics features were analyzed with unsupervised hierarchical cluster analysis. A random forest (RF) model was used to identify radiomics features important for differentiating fpAML from ccRCC in the development cohort. The diagnostic performance of the RF model was evaluated in the development and validation cohorts.

The cases in the developmental cohort were classified into three groups with different frequencies of fpAML by cluster analysis of radiomics features. RF analysis of the development cohort showed that the mean ADC value was important for differentiating fpAML from ccRCC, as well as higher-texture features including gray-level run length matrix (GLRLM)_long-run low gray-level enhancement (LRLGE), and GLRLM_low gray-level run emphasis (LGRE). The area under the curve values of the development [0.90, 95% confidence interval (CI) 0.80-1.00] and validation cohorts (0.87, 95% CI 0.74-1.00) were similar (P = 0.91).

The radiomics features of ADC maps are useful for differentiating fpAML from ccRCC.

Somatostatin receptor (SSTR) PET has now emerged as the reference standard for the evaluation of NENs and is particularly critical in the context of peptide receptor radionuclide therapy (PRRT) eligibility. SSTR PET/MRI with liver-specific contrast agent has a strong potential for one-stop-shop multiparametric evaluation of GEP-NENs. 18F-FDG is a complementary radiotracer to SSTR, especially in the context of high-grade neuroendocrine neoplasms. Knowledge gaps in quantitative evaluation of molecular imaging studies and their role in assessment of response to PRRT and combination therapies are active research areas. Selleck Colivelin Novel radiotracers have the potential to overcome existing limitations in the molecular imaging of GEP-NENs. The purpose of this article is to provide an overview of the current trends, pitfalls, and recent advancements of molecular imaging for GEP-NENs.We report a case of congenital capillary proliferation of the kidney (CCPK) along with the multimodality imaging findings. Four-day-old boy who had managed due to his mother's gestational diabetes underwent abdominal ultrasound and a mass was detected in the right kidney. On gray scale ultrasound, the mass exhibited a hyperechoic, slight lobulated shape and a circumscribed margin. On Doppler mode, the mass showed hypervascularity in its peripheral to central zones. On MRI, the mass was hyperintense on the T2-weighted image, and no diffusion restriction was noted on DWI/ADC. On computed tomography, strong enhancement was shown at center of the mass at the post-contrast early phase; homogeneous enhancement at the entirety of the mass was observed at the delayed phase. We suspected hemangioma but did not rule out the possibility of malignancy. Surgery was performed. Pathologically, the specimen showed a proliferation of capillaries which were positive for vascular endothelial markers and negative for GLUT1 in immunohistochemistry. A small number of entrapped tubules and glomeruli were also observed. After an intensive pathological examination, the diagnosis of CCPK was finally considered. CCPK was recently described as an extremely rare childhood renal vascular lesion, and to our knowledge, only five other cases have been reported. Our patient's multimodality imaging findings well reflected the characteristics of a vascular lesion.Isomerization of aspartic acid (Asp) residues in long-lived proteins is a key feature associated with neurodegenerative proteinopathies such as Alzheimer's disease (AD). Recently, using ultra high-performance liquid chromatography (UHPLC) coupled with drift tube ion mobility mass spectrometry (DTIMS-MS), we documented the extensive Asp isomerization in amyloid-beta (Aβ) peptides depositing in the extracellular cortical plaques (senile plaques) of the AD brain. Aβ1-15 was estimated to be ~ 85% isomerized, while Aβ4-15 another major constituent of these senile plaques was ~ 50% isomerized in AD brain. Low resolution on the standard demultiplexed ion mobility resulted in poor separation of these N-truncated Aβ isomers in the ion mobility domain. Here, using the same ion multiplexed dataset, we applied new post-acquisition data reconstruction technique, high-resolution demultiplexing (HRdm), to improve the resolution of these Aβ isomers in the ion mobility dimension. We demonstrate that for the complex proteomic AD brain digests, HRdm could successfully resolve three out of four major Asp isomers of Aβ1-15. For Aβ2-15 and Aβ4-15, the significant resolution enhancement in the HRdm data resulted in baseline peak separation of the respective Asp isomers. An analysis of two-peak resolution (Rpp) and peak-to-peak separation (ΔP) indicated twofold enhancement for the Asp-isomerized Aβ species. HRdm performed with an effective resolving power (Rp) of between 150 and 160 for the highest deconvolution settings in comparison to ~ 40 to 65 in the standard settings. These major resolution improvements in the ion mobility domain for the endogenous Aβ isomers demonstrate the feasibility of in situ measurement of peptide isomers and their role in the mechanism of amyloid plaque formation in AD.Lateral flow assays (LFAs) widely deployed for on-site diagnosis have predominantly utilized antibodies as recognition molecules. Antibodies with limited thermal stability deteriorate the performance of the LFA over time. Herein, we demonstrate a stable and robust LFA by utilizing thermally stable peptide-based 12-14 kDa affimers as recognition molecules, in lieu of conventional protein-based antibodies to analyze complex samples with a significantly improved shelf life at room temperature. The model system studied here is that of interleukin-8 (IL8) biomarker for validating the efficacy of the proposed approach, using a pair of affimer probes that demonstrates dual functionality of capturing and reporting. Affimers immobilized on the test zone of LFA serve as capture probes for IL8-affimer-MB complexes. Whereas affimers conjugated with the MBs that enable extraction of IL8 from the sample matrix serve as reporters for visual detection. The MB complexes captured at the test zone resulted in brownish test bands that enable concentration-dependent detection of IL8. The assay yielded sensitive visual detection of IL8 at ng/mL levels (~ 0.1 ng/mL and 1 ng/mL in buffer and human plasma, respectively), within 20 min, using sample volumes of ~ 100 µL. Importantly, the stability of affimer-incorporated LFA improved significantly in contrast to antibody-incorporated LFA over time, even when stored at 4 °C. Therefore, the proposed affimer-based LFA in conjunction with MBs offer stable and reliable detection of biomarkers at clinically relevant concentration ranges in complicated matrices, even without requiring cold storage, hence, offering a promising avenue for on-site diagnosis in resource-limited settings.
