Research has shown that patients with post-stroke aphasia may encounter difficulties in producing inflectional morphemes. Interestingly, they also show distinct challenges with the inflectional morphemes of homophones, such as the plural marker and the possessive marker in English. However, previous studies have predominantly focused on morphemes in European languages.

With the advancement of computer technology and imaging equipment, ultrasound has emerged as a crucial tool in breast cancer diagnosis. To gain deeper insights into the research landscape of ultrasound in breast cancer diagnosis, this study employed bibliometric methods for a comprehensive analysis spanning from 2004 to 2024, analyzing 3523 articles from 2176 institutions in 82 countries/regions. Over this period, publications on ultrasound diagnosis of breast cancer showed a fluctuating growth trend from 2004 to 2024.

Article Synopsis
  • The study aimed to identify factors that predict upgrading in Gleason Grading Group (GGG) in low-risk prostate cancer patients who had undergone radical prostatectomy, focusing on data from 160 patients.
  • Key independent predictors found were age, the ratio of free to total prostate-specific antigen (f/tPSA), and positive targets in MRI, with a predictive model showing significant accuracy.
  • Results indicated that as GGG levels increased, the number of patients who experienced upgrading also increased, demonstrating distinct trends based on these predictive factors.

Objective: To evaluate the diagnostic performance of different ultrasound sections of thyroid nodule (TN) using computer-aided diagnosis system based on artificial intelligence (AI-CADS) in predicting thyroid malignancy.

Materials And Methods: This is a retrospective study. From January 2019 to July 2019, patients with preoperative thyroid ultrasound data and postoperative pathological results were enrolled, which were divided into two groups: lower risk group (ACR TI-RADS 1, 2 and 3) and higher risk group (ACR TI-RADS 4 and 5).

Purpose: The aim of this study was to investigate the value of S-Detect for predicting the malignant risk of cytologically indeterminate thyroid nodules (CITNs).

Methods: The preoperative prediction of 159 CITNs (Bethesda III, IV and V) were performed using S-Detect, Thyroid Imaging Reporting and Data System of American College of Radiology (ACR TI-RADS) and Chinese TI-RADS (C-TIRADS). First, Linear-by-Linear Association test and chi-square test were used to analyze the malignant risk of CITNs.

The clinical data of 15 cases that planned to receive totally laparoscopic associating liver partition and portal vein ligation for staged hepatectomy were retrospectively collected. Before the stage 1 operation, the size and number of the tumors in future liver remnant (FLR) and the presence of cancer embolus in the portal vein were assessed using contrast-enhanced ultrasound (CEUS) and contrast-enhanced computed tomography (CECT). Before the stage 2 operation, CEUS was performed to assess the presence of traffic blood flow between the diseased liver and FLR after round-the-liver ligation.

Purpose: To explore the utility of the BRAF mutation in combination with the Chinese Thyroid Imaging Reporting and Data System (C-TIRADS) in the management of atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) thyroid nodule (TN).

Methods: 138 AUS/FLUS TNs in 129 patients were included. Each TN underwent preoperative BRAF mutation analysis and was classified using the C-TIRADS.

For oil sand reservoirs, the steam-assisted gravity drainage (SAGD) technique is one of the most efficient thermal recovery technologies. However, the high oil viscosity and the severe heat loss seriously affect the production effect of SAGD in developing thin oil sand reservoirs by the traditional SAGD technology. Therefore, it is essential to improve the SAGD technology to enhance the recovery of the thin oil sand reservoir.

Purpose The purpose of this study was to measure Mandarin Chinese vowel-plus-tone identification in quiet and noise for younger and older listeners. Method Two types of noise served as the masker, namely, six-talker babble and babble-modulated noise, at two signal-to-noise ratios (SNRs) of -4 and -8 dB. Fourteen listeners from both age groups were recruited, and three sets of data analyses were conducted: the identification of vowel plus tone, the identification of vowel, and the identification of tone.

Background: Polyacrylamide hydrogel (PAAG) injections were once common in breast augmentation and have been prohibited for augmentation mammaplasty in China since a large number of patients who underwent breast augmentation with PAAG injections have continued to seek medical advice as a result of related complications. Among all these complications, distant migration is relatively rare.

Case Summary: A 49-year-old female presented at the hospital with a one-year history of a vulvar lump.

Purpose: To assess alteration of diaphragmatic function by ultrasonography in a population of mechanically ventilated patients with or without sepsis.

Methods: We performed a prospective, 6-month, single-center, observational cohort study. Mechanically ventilated septic and nonseptic patients were studied within 24 hours following intubation and before the moment of ventilator liberation.

Purpose: The purpose of the study was to examine the aging effect on the categorical perception of Mandarin Chinese Tone 2 (rising F0 pitch contour) and Tone 3 (falling-then-rising F0 pitch contour) as well as on the thresholds of pitch contour discrimination.

Method: Three experiments of Mandarin tone perception were conducted for younger and older listeners with Mandarin Chinese as the native language. The first 2 experiments were in the categorical perception paradigm: tone identification and tone discrimination for a series of stimuli, the F0 contour of which systematically varied from Tone 2 to Tone 3.

Objective: To investigate the value of thyroglobulin measurement in ultrasound guided fine-needle aspiration(FNA-Tg)for detecting neck node metastasis in patients with papillary thyroid carcinoma(PTC)after thyroidectomy.

Methods: A total of 128 suspicious metastatic lymph nodes in 112 patients were retrospectively analyzed. Postoperative pathologic results were taken as the gold standard.

Mandarin Chinese speech sounds (vowels × tones) were presented to younger and older Chinese-native speakers with normal hearing. For the identification of vowel-plus-tone, vowel-only, and tone-only, younger listeners significantly outperformed older listeners. The tone 3 identification scores correlated significantly with the age of older listeners.

Enlargement of the left atrium is an independent predictor of adverse cardiovascular outcomes, and an accurate, convenient imaging modality is necessary for clinical practice. The objectives of this study were to evaluate the feasibility of a novel imaging technique, two-dimensional tissue tracking (2DTT), for assessment of left atrial (LA) volume and function and to compare its correlation and agreement with biplane area length (AL) method and real time three-dimensional echocardiography (RT3DE). A total of 105 patients prospectively underwent 2DTT, AL and RT3DE.

A novel echocardiographic method, vector flow mapping (VFM), acquires velocity vector from color Doppler velocity data. The purpose of this study was to evaluate whether VFM could provide useful information on intracardiac flow and helpful to evaluate left ventricular (LV) function. Thirty-eight patients with uremia undergoing hemodialysis and 30 healthy volunteers were enrolled.
