In Houston, a total of 4808 cases were assessed. There was an initial drop of~30% in cases at the pandemic onset. Compared to 2019, there was a significant reduction in mild strokes (NIHSS 1-5) [N (%), 891 (43) vs 635 (40), P=0.02]. There were similar mean (SD) (mins) DTN [44 (17) vs 42 (17), P=0.14] but significantly prolonged DTG times [94 (15) vs 85 (20), P=0.005] in 2020. The COVID-19 pandemic led to a global reduction in stroke admissions and treatment interventions and prolonged treatment time metrics. The COVID-19 pandemic led to a global reduction in stroke admissions and treatment interventions and prolonged treatment time metrics. We evaluated the various accompanied malformations in patients with anal atresia or tracheoesophageal fistula (TEF). Furthermore, we determined the prevalence of VACTERL association and compared the clinical findings with those of patients without VACTERL association. We enrolled the patients with anal atresia or TEF with/without esophageal atresia. We collected the patient data pertaining to accompanied vertebral, cardiovascular, renal or limb anomalies, single umbilical artery, maternal diabetes mellitus or drug history, and gene research. A total 155 patients (65 boys and 90 girls) were enrolled with 147 cases of anal atresia, 3 cases of TEF, and 5 cases of anal atresia with TEF. The prevalence of accompanied anomalies was 67.1% in cardiovascular, 27.1% in renal, 9.7% in vertebral, 2.6% in limb anomalies, and 3.9% in single umbilical artery. Thirty-six (23.2%) patients were diagnosed with VACTERL association. The patients with VACTERL association had a significantly higher number of male patients (58.3 vs. 37.0%, p = .033) and single umbilical artery (11.1 vs. 1.7%, p = .026), and had a significantly lower birth weight (2.8 vs. 3.1 kg, p = .033) than the patients without VACTERL association. Genetic studies were performed in 111 patients, and 8 (7.2%) had chromosomal abnormalities-3 in VACTERL and 5 in no VACTERL group. We recommend a careful evaluation for VACTERL association in patients with anal atresia or TEF. It is particularly important to screen for a single umbilical artery for features of VACTERL association as well as for other congenital anomalies.

To validate a synthetic computed tomography (sCT) software with continuous HUs and large field-of-view (FOV) coverage for magnetic resonance imaging (MRI)-only workflow of general pelvis anatomy in radiotherapy (RT). An sCT software for general pelvis anatomy (prostate, rectum, and female pelvis) has been developed by Philips Healthcare and includes continuous HUs assignment along with large FOV coverage. General pelvis sCTs were generated using a two-stack T1-weighted mDixon fast-field echo (FFE) sequence with a superior-inferior coverage of 36cm. Seventy-seven prostate, 43 rectum, and 27 gynecological cases were scanned by three different institutions. mDixon image quality and sCTs were evaluated for soft tissue contrast by using a confidence level scale from 1 to 5 for bladder, prostate/rectum interface, mesorectum, and fiducial maker visibility. Dosimetric comparison was performed by recalculating the RT plans on the sCT after rigid registration. For 12 randomly selected cases, the mean absolute error.4±4.1HU, respectively. Average PCC of all evaluated DRR pairs was 0.975. The average offset between CT and sCT as reference was (LR, AP, SI)=(0.19±0.35, 0.14±0.60, 0.44±0.54)mm. The continuous HU sCT software-generated realistic sCTs and DRRs to enable MRI-only planning for general pelvis anatomy.

This study aimed to investigate the correlation of sirtuin 2 (SIRT2) with acute ischemic stroke (AIS) risk, severity, inflammation, and prognosis. A hundred and sixty-four first episode AIS patients and 164 age and gender matched non-AIS patients with high-stroke-risk factors (controls) were enrolled. Peripheral blood was collected and serum was separated for SIRT2 and pro-inflammatory cytokines detection by enzyme-linked immunosorbent assay. AIS patients were continually followed up to 36months or death, then recurrence-free survival (RFS) and overall survival (OS) were calculated. Serum SIRT2 expression was increased in AIS patients compared to controls (p<0.001), then receiver operative characteristic curve disclosed that the serum SIRT2 expression could differentiate AIS patients from controls with a good area under curve of 0.890 (95%CI 0.854-0.926), a sensitivity of 78.7% and a specificity of 91.5% at the best cut-off point. Serum SIRT2 expression was positively correlated with National Institute of Health stroke scale score (p<0.001), serum tumor necrosis factor-α (p<0.001), interleukin (IL)-6 (p=0.012) and IL-17 (p<0.001) expressions in AIS patients. In addition, serum SIRT2 expression was elevated in recurrent/dead AIS patients compared to non-recurrent/dead AIS patients (p=0.025), and was also increased in dead AIS patients compared to survivors (p=0.006). Moreover, RFS (p=0.029) and OS (p=0.049) were both worse in AIS patients with SIRT2 high expression compared to AIS patients with SIRT2 low expression. SIRT2 may serve as a marker for AIS risk and prognosis in clinical practice. SIRT2 may serve as a marker for AIS risk and prognosis in clinical practice. Angiopoietin-like protein 4 (ANGPTL-4) had been reported to be associated with the risk of ischemic stroke, but its prognostic value remained unclear. The aim of this study was to investigate the association between plasma ANGPTL-4 concentrations and prognosis of ischemic stroke. Baseline plasma ANGPTL-4 concentrations were measured in 3379 acute ischemic stroke patients. The primary outcome was a combination of death or major disability (modified Rankin Scale score, ≥3) at 3months after ischemic stroke. At 3months after ischemic stroke, 850 (26.16%) participants experienced major disability or died (750 major disabilities and 100 deaths). After adjusting for important covariates, odds ratios for the highest tertile of plasma ANGPTL-4 concentrations were 1.59 (1.22-2.06) for primary outcome, 1.53 (1.18-1.97) for major disability, and 2.03 (1.03-4.00) for death when compared with the lowest tertile of plasma ANGPTL-4 concentrations. For 1-SD increase in log-ANGPTL-4 concentrations (0.44ng/mL), the adjusted odds ratios were 1.
