Background: Contrast-enhanced ultrasound (CEUS) has been used as an additional imaging technique to conventional ultrasound in order to clarify gallbladder findings, CEUS is easy and fast to perform, overcomes the limitations of gray-scale ultrasonography and is a safe tool.
Objective: The aim of this retrospective mono-center analysis study is to evaluate the diagnostic performance of CEUS in the assessment of gallbladder disease by comparing its results with additional CT findings.
Methods: A total of 24 patients between 2009 and 2017 with unclear gallbladder appearance were retrospectively analysed. The contrast agent administered was a second-generation blood pool agent (SonoVue®, Bracco, Milan, Italy). Examinations were performed and interpreted by a single experienced radiologist with more than fifteen years' experience.
Results: 24 patients were successfully examined without any adverse reaction. CEUS presented a sensitivity of 75%, a specificity of 100.0%, a positive predictive value of 100.0% and a negative predictive value of 95%.
Conclusions: In conclusion, the excellent results in this study acknowledged that CEUS is a feasible alternative tool to differentiate gallbladder pathologic alterations.

VA Center for Health Information and Communication, US Department of Veterans Affairs, Veterans Health Administration, Health Systems Research CIN 13-416, Richard L. Roudebush VA Medical Center, Indianapolis, Indiana.
Importance: Compared with cisgender (CG) individuals, transgender and gender-diverse (TGD) individuals experience substantial social and economic disparities that can result in adverse mental health consequences. It is critical to understand potential barriers to care and to address the causes of the disparities in the future.
Objective: To characterize mental health care utilization among TGD veterans with depression.

Purpose: To investigate potential modes of programmed cell death in the lens epithelial cells (LECs) of patients with early age-related cortical cataract (ARCC) and to explore early-stage intervention strategies.
Methods: Anterior lens capsules were collected from early ARCC patients for comprehensive analysis. Ultrastructural examination of LECs was performed using transmission electron microscopy.

Background: Computed tomography (CT)-derived low muscle mass is associated with adverse outcomes in critically ill patients. Muscle ultrasound is a promising strategy for quantitating muscle mass. We evaluated the association between baseline ultrasound rectus femoris cross-sectional area (RF-CSA) and intensive care unit (ICU) mortality.
