To evaluate the diagnostic values of shear wave elastography (SWE) alone and in combination with the Toronto clinical scoring system (TCSS) on diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes mellitus (T2DM). The study included 41 DPN patients, 42 non-DPN patients, and 21 healthy volunteers. Conventional ultrasonography and SWE were performed on the 2 sides of the tibial nerves, and cross-sectional area (CSA) and nerve stiffness were measured. ⋯ Mean elasticity of the tibial nerve with a cutoff of 71.3 kPa was the most sensitive (68.3%) and had a higher area under the curve (0.712; 0.602-0.806) among the 3 shear elasticity indices for diagnosing DPN when used alone. When combining SWE with TCSS in diagnosing DPN, the most effective parameter was the EMax, which yielded a sensitivity of 100.00% and a specificity of 95.24%. SWE is a better diagnostic tool for DPN than the conventional ultrasonic parameter CSA, and a higher diagnostic value is attained when combining SWE with TCSS.

Observational Study
Coronavirus disease 2019 pandemic, restriction, and orthopedic trauma: Retrospective observational study.
In 2019, the Coronavirus disease 2019 (Covid-19) was reported in Wuhan, China. Governments in various countries had taken many safeguards. This study investigated the incidence of orthopedic trauma in a rural region epidemiologically and guided source distribution and medical professionals to sustain healthcare systems. ⋯ There were significant differences between admission dates and the fractures (P < .001). In this study, a decrease in orthopedic trauma rates was observed by half in the restriction period compared with the other 2 periods. Public health precautions had led to a reduction in the incidence of orthopedic trauma in all age groups.

To investigate the difference in chorioretinal microcirculation between acute central serous chorioretinopathy (aCSC) and chronic central serous chorioretinopathy (cCSC) using optical coherence tomography angiography. In total, 65 patients previously diagnosed with central serous chorioretinopathy (33 aCSC and 32 cCSC) were included in our cross-sectional study. All patients underwent complete ophthalmologic assessment including logarithm of the minimum angle of resolution best-corrected visual acuity, fundus fluorescein angiography, and optical coherence tomography angiography. ⋯ Further analysis of the data reveals the presence of a distinct choroidal neovascularization (CNV) in 8 patients (25%) with cCSC while there was no evidence of CNV in patients with aCSC. Our study can contribute to a better understanding of the difference in retinochoroid microcirculation between aCSC and cCSC. The vessel density of inner retina was lower and the vessel density of superficial choroid was higher in cCSC, and patients with cCSC were more susceptible to CNV than patients with aCSC.

The aim of this study was to retrospectively analyze 18F-FDG positron emission tomography/computed tomography (18F-FDG PET/CT) metabolic variables, programmed death-ligand 1 (PD-L1) and phosphorylated signal transducer and activator of transcription 3 (p-STAT3) tumor expression, and other factors as predictors of disease-free survival (DFS) in patients with lung adenocarcinoma (LUAD) (stage IA-IIIA) who underwent surgical resection. We still lack predictor of immune checkpoint (programmed cell death-1 [PD-1]/PD-L1) inhibitors. Herein, we investigated the correlation between metabolic parameters from 18F-FDG PET/CT and PD-L1 expression in patients with surgically resected LUAD. ⋯ The results indicated that TNM stage, PD-L1 positivity, and high 18F-FDG PET/CT metabolic volume parameters (TLG ≥90.85 or MTV ≥14.87) were independent predictors of worse DFS in resected LUAD. No 18F-FDG metabolic parameters associated with PD-L1 expression were observed (chi-square test), but we found that patients with positive PD-L1 expression have significantly higher SUVmax (P = .01), MTV (P = .00), and TLG (P = .00) than patients with negative PD-L1 expression.18F-FDG PET/CT metabolic volume parameters (TLG ≥90.85 or MTV ≥14.87) were more helpful in prognostication than the conventional parameter (SUVmax), PD-L1 expression was an independent predictor of DFS in patients with resected LUAD. Metabolic parameters on 18F-FDG PET/CT have a potential role for 18F-FDG PET/CT in selecting candidate LUAD for treatment with checkpoint inhibitors.

This retrospective study appraised the preventive effect of statin after carotid artery stenting (CAS). Records were extracted for 100 patients with CAS surgery indicator, aged between 20 and 75 years old, and treated for statin. The cohort study included treatment group (statin and routine treatment) and control group (routine treatment), each group 50 patients. ⋯ After treatment, there were no significant differences in National Institute of Health Stroke Scale, lipid profiles, and mortality rate between 2 groups. However, significant differences in total cholesterol (mg/dL, P = .03), low-density lipoprotein (mg/dL, P = .01), transient ischemic attack (P = .03), ischemic stroke (P = .04), and cardiac complications (P = .03) were identified within 30 days after CAS between 2 groups. The results of this study showed that prior statin treatment may be effective for the prevention of CAS complications.
