Objectives: A liver stiffness × spleen size/platelet count score (LSPS) model which can rule out high-risk varices and identify high likelihood of clinically significant portal hypertension in patients with compensated cirrhosis has been endorsed by American Association for the Study of Liver Diseases in the 2016 practice guidance on portal hypertension bleeding. This study aims to evaluate the accuracy of LSPS model assessed by ultrasound in well characterized patients with compensated advanced chronic liver disease.
Methods: Eligible patients with compensated advanced chronic liver disease were retrospectively enrolled between January 2017 and March 2018, who had undergone routine clinical and laboratory tests, liver stiffness measurement, ultrasound examination, and computed tomography scanning. Spleen sizes were evaluated by ultrasound and computed tomography reconstructed model, respectively. The correlation and agreement of spleen size and LSPS derived from ultrasound and computed tomography imaging modality were compared.
Results: A total of 158 patients were included and analyzed. Spleen size showed a moderate correlation (R = 0.649, P < 0.001) according to ultrasound and computed tomography imaging. Also, the correlation between the two LSPS models based on ultrasound and computed tomography was excellent (R = 0.985, P < 0.001). The Bland-Altman plots demonstrated a superior agreement of LSPS model values evaluated by ultrasound and computed tomography, respectively.
Conclusion: This study demonstrated the accuracy of LSPS model based on ultrasound in a well characterized cohort of fully compensated patients with advanced chronic liver disease.

Multiple sclerosis (MS) falls within the spectrum of central nervous system (CNS) demyelinating diseases that may lead to permanent neurological disability. Fundamental to the diagnosis and clinical surveillance is magnetic resonance imaging (MRI) that allows for the identification of T2-hyperintensities associated with autoimmune injury that demonstrate distinct spatial distribution patterns. Here, we describe the clinical experience of a 31-year-old, right-handed, White man seen in consultation at The University of Texas Southwestern Medical Center in Dallas, Texas, following complaints of headaches that began after head trauma related to military service.

3D multifunctional wearable piezoresistive sensors have aroused extensive attention in the fields of motion detection, human-computer interaction, electronic skin, etc. However, current research mainly focuses on improving the foundational performance of piezoresistive sensors, while many advanced demands are often ignored. Herein, a 3D piezoresistive sensor based on rGO@C-ZIF-67@PU is fabricated via high temperature carbonization and a solvothermal reduction method.

This target product profile (TPP) highlights the minimal and optimal characteristics for ex-vivo and in-vivo cell and gene therapy-based products aimed at achieving an HIV cure (ie, durable antiretroviral-free viral control). The need for an effective, safe, scalable, affordable, accessible, and acceptable cure for HIV infection remains a major global priority. The possibilities for cell and gene therapy-based products for an HIV cure are rapidly expanding.

Colloidal quantum-dot light-emitting diodes (QD-LEDs) have been significantly improved in terms of device performance and lifetime by employing zinc oxide (ZnO) as an electron transport layer (ETL). Although atomic layer deposition (ALD) allows fabrication of uniform, high-quality ZnO films with minimal defects, the high conductivity of ZnO has hindered its straightforward application as an ETL in QD-LEDs. Herein, we propose fabrication of Al-doped ZnMgO (Al:ZnMgO) ETLs for QD-LEDs through a supercycle ALD, with alternating depositions of various metal oxides.
