This paper provides guidelines for the optimal, rather than minimal, performance of ultrasonic examination of the heart for current clinical applications using conventional echocardiographic equipment. Since the original report of this Inter-Society Commission on Heart Disease Resources Committee in 1975, M-mode echocardiography has continued to be a valuable clinical tool, and two-dimensional echocardiography has been developed. Guidelines are presented for optimal physician and cardiac sonographer training, case loads, space and support systems, equipment design features and performance testing, and administrative considerations. The developing area of Doppler ultrasound and the competitive technologies are noted.

Immunogenic cell death (ICD) offers a promising avenue for the treatment of triple-negative breast cancer (TNBC). However, optimizing immune responses remains a formidable challenge. This study presents the design of RBCm@Pt-CoNi layered double hydroxide (RmPLH), an innovative sonosensitizer for sonodynamic therapy (SDT), aimed at enhancing the efficacy of programmed cell death protein 1 (PD-1) inhibitors by inducing robust ICD responses.

Department of Medical Ultrasonics, First Affiliated Hospital of Medical College, Xi'an Jiao tong University, No.277 Yanta West Road, Xi'an, 710061, Shaanxi, China.
Background: Abdominal aortic calcification (AAC) is considered as a strong predictor of cardiovascular disease (CVD) events. Our study aimed to investigate whether the predicted risk for cardiac death with the Framingham risk score (FRS) could be further improved with the addition of AAC score in general population aged ≥ 40 years.
Methods: A total of 2971 participants aged ≥ 40 years in the National Health and Nutrition Examination Surveys (NHANES) 2013-2014 were followed up.
Diagnostic Performance of O-RADS US (Version 2019 and Version 2022) Incorporating Acoustic Shadowing by Junior Radiologists: Analyzing 1061 Adnexal Masses.

Department of Ultrasonic Medicine, Fetal Medical Centre, The First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China.
Introduction: Acoustic shadowing is an important benign ultrasound (US) feature for adnexal masses (AMs). To validate the diagnostic performance and interobserver agreement of the 2019 version and 2022 version of Ovarian-Adnexal Reporting and Data System Ultrasound (O-RADS US) and ascertain whether adding acoustic shadowing to O-RADS US v2019 as a benign ultrasound feature can enhance its diagnostic efficacy among junior radiologist.
Methods: This retrospective study included consecutive women with suspected adnexal masses who underwent ultrasound examinations between September 2022 and January 2024.
Structural and load-dependent arterial stiffness across the adult life span.
J Hypertens
December 2024
Department of Ultrasound Medicine, Tangdu Hospital, Air Force Medical University.
Background: The arterial stiffening is attributed to the intrinsic structural stiffening and/or load-dependent stiffening by increased blood pressure (BP). The respective lifetime alterations and major determinants of the two components with normal aging are not clear.
Methods: A total of 3053 healthy adults (1922 women) aged 18-79 years were enrolled.
5.6% lidocaine aerosol anesthesia for supragingival ultrasonic scaling in patients with chronic periodontitis or dental plaque-induced gingivitis.

Department of Periodontology, Peking University School and Hospital of Stomatology, National Clinical Research Center for Oral Diseases, National Engineering Laboratory for Digital and Material Technology of Stomatology, Beijing Key Laboratory of Digital Stomatology, No. 22 Zhongguancun South Street, Haidian District, Beijing, 100081, China.
The aim of this study was to evaluate the efficacy and patient satisfaction of lidocaine aerosol for pain management during periodontal scaling and root planning in patients with chronic periodontitis or dental plaque-induced gingivitis. This study specifically concentrated on comparing the effectiveness of lidocaine aerosol as a topical anesthetic against a placebo, assessing its impact on pain perception during the procedure. Additionally, the relationship between periodontal treatment and the reduction of oxidative stress markers in these patients was assessed.
