Elastography and contrast-enhanced ultrasound to assess the effect of varicocelectomy: A case-controlled study.

To evaluate the changes in testicular stiffness and microcirculation caused by spermatic vein ligation in patients with varicocele, we conducted a case-controlled study. A total of 27 grade III left varicocele cases were enrolled. Testicular stiffness and perfusion were evaluated by shear wave elastography and contrast-enhanced ultrasound during subinguinal microscopic varicocelectomy.

Validation of two risk assessment models for venous thromboembolism in patients undergoing gynecologic surgery.

Background: According to published guidelines, gynecologic surgical patients should be stratified into different risk level groups to receive prophylaxis for venous thromboembolism (VTE), but the applicability of available risk assessment models (RAMs) in common gynecologic surgical patients remained to be confirmed. We aimed to validate the use of the Caprini RAM and gynecologic Caprini (G-Caprini) RAM for assessing postoperative VTE risk in gynecologic surgical patients.

Methods: The database of a randomized controlled trial (RCT) was used to select patients who underwent gynecologic surgeries for benignant and malignant diseases in five institutions in China between 2011 and 2018.

Specification and guideline for technical aspects and scanning parameter settings of neonatal lung ultrasound examination.

Lung ultrasound (LUS) is now widely used in the diagnosis and monitor of neonatal lung diseases. Nevertheless, in the published literatures, the LUS images may display a significant variation in technical execution, while scanning parameters may influence diagnostic accuracy. The inter- and intra-observer reliabilities of ultrasound exam have been extensively studied in general and in LUS.

The Value of Preoperative and Intraoperative Ultrasound in the Localization of Intrathyroidal Parathyroid Adenomas.

Methods: Between June 2016 and December 2018, a total of 30 patients with symptomatic uterine fibroids (≥5cm) who underwent transvaginal US-guided RFA combined with mifepristone were included in this retrospective study. A matching cohort of 30 patients underwent transvaginal US-guided RFA without mifepristone as controls.

Ultrasound-guided transvaginal radiofrequency ablation combined with levonorgestrel-releasing intrauterine system for symptomatic uterine adenomyosis treatment.

Objective: To evaluate the clinical outcomes of transvaginal ultrasound-guided radiofrequency ablation (RFA) combined with a levonorgestrel-releasing intrauterine system (LNG-IUS) for the treatment of symptomatic uterine adenomyosis.

Methods: Patients with symptomatic uterine adenomyosis treated with ultrasound-guided RFA in combined with an LNG-IUS from January 2013 to January 2016 and followed up for 3 years after treatment were selected. Assessment endpoints included the uterine volume reduction rate, dysmenorrheal score, symptom severity score and adverse events.

Coherently forming a single molecule in an optical trap.

Ultracold single molecules have wide-ranging potential applications, such as ultracold chemistry, precision measurements, quantum simulation, and quantum computation. However, given the difficulty of achieving full control of a complex atom-molecule system, the coherent formation of single molecules remains a challenge. Here, we report an alternative route to coherently bind two atoms into a weakly bound molecule at megahertz levels by coupling atomic spins to their two-body relative motion in a strongly focused laser with inherent polarization gradients.

Application of lung ultrasonography in critically ill patients with COVID-19.

Purpose: Lung ultrasonography (LU) is useful to assess lung lesions and variations at bedside. To investigate the results of LU in severe and critical patients with coronavirus disease 2019 (COVID-19), we performed a single-institution study to evaluate the related lung lesions and variations, and prophylactic strategies, in a large referral and treatment center.

Methods: We included 91 adult patients with severe and critical COVID-19, namely 62 males and 29 females, with an average age of 59 ± 11 years, who underwent LU.

Applicability of bedside ultrasonography for the diagnosis of deep venous thrombosis in patients with COVID-19 and treatment with low molecular weight heparin.

Purpose: The aim of this study was to evaluate the applicability of bedside ultrasonography for the diagnosis of deep venous thrombosis (DVT) in patients infected with corona virus disease 2019 (COVID-19) with and without treatment with low molecular weight heparin (LMWH).

Methods: We retrospectively analyzed the records of deceased and surviving patients in whom ultrasonography detected or not a DVT, and in whom LMWH was or not prescribed.

Results: The incidence of DVT is higher in the deceased (33/35) than in the surviving (22/46) patients.

Balanced Coherence Times of Atomic Qubits of Different Species in a Dual 3×3 Magic-Intensity Optical Dipole Trap Array.

We construct a polarization-mediated magic-intensity (MI) optical dipole trap (ODT) array, in which the detrimental effects of light shifts on the mixed-species qubits are efficiently mitigated so that the coherence times of the mixed-species qubits are both substantially enhanced and balanced for the first time. This mixed-species magic trapping technique relies on the tunability of the coefficient of the third-order cross term and ground state hyperpolarizability, which are inherently dependent on the degree of circular polarization of the trapping laser. Experimentally, polarization of the ODT array for ^{85}Rb qubits is finely adjusted to a definite value so that its working magnetic field required for magic trapping amounts to the one required for magically trapping ^{87}Rb qubits in another ODT array with fully circular polarization.

Application of ultrasound fusion imaging technique for unilateral percutaneous vertebroplasty in treatment of osteoporotic thoracolumbar compression fracture.

Objective: To evaluate application of a computed tomography (CT)-ultrasound fusion imaging technique to unilateral percutaneous vertebroplasty (PVP) for treating patients with osteoporotic thoracolumbar compression fracture.

Patients in the first group underwent unilateral PVP using real-time CT-ultrasound fusion imaging.

Asymmetric biomechanical characteristics of the paravertebral muscle in adolescent idiopathic scoliosis.

Background: We sought to assess the biomechanical properties of the paravertebral muscles in adolescent idiopathic scoliosis patients with Lenke Type 1, 2, or 3 (Lenke 1-3) curves.
