Effects of Adding Ultrasound Biofeedback to Individualized Pelvic Floor Muscle Training on Extensibility of the Pelvic Floor Muscle and Anterior Pelvic Organ Prolapse in Postmenopausal Women.

The aim of the study was to determine effects of adding transperineal ultrasound (TPUS) biofeedback to individualized pelvic floor muscle training (PFMT) on extensibility of the pelvic floor muscle and anterior pelvic organ prolapse (POP) in postmenopausal women. A total of 77 patients with POP at stage I or stage II were admitted to Beijing Shijitan Hospital, China, from January 2017 to October 2018. They were randomly divided into a control group (CG) ( = 37) or a study group (SG) ( = 40).

Investigating the effectiveness of COVID-19 pandemic countermeasures on the use of public transport: A case study of The Netherlands.

During the COVID-19 pandemic, public transport in many cities faces dramatic reduction of passenger demand. Various countermeasures such as social distancing and in-vehicle disinfection have been implemented to reduce the potential risks concerning infection, the effectiveness in promoting the use of public transport however remains unclear. Unlike the usual situation where time and cost are the main factors affecting travel decisions, the uncertainty hiding behind the behavior change of public transport users in a pandemic might be greatly affected by the control measures and the perception of people.

Role of latent factors and public policies in travel decisions under COVID-19 pandemic: Findings of a hybrid choice model.

Policy measures to control the spread of COVID-19 imposed by different countries have a devastating impact on people's travel behaviors. Differing from the normal situation where general concerns on travel time and cost determine the travel choices, the uncertainty underlying behavior change in the case of a pandemic might be largely attributed to the latent aspects, i.e.

Contrast-enhanced ultrasound in uterine artery embolization treatment of cesarean scar pregnancy.

Objective: The current study aimed to investigate the application of contrast-enhanced ultrasound (CEUS) in diagnosis and treatment of cesarean scar pregnancy (CSP).

Methods: A retrospective study was performed in 35 patients with clinically suspected CSP who requested termination of pregnancy and underwent contrast-enhanced ultrasound (CEUS). The patients were classified into two groups on the basis of whether they received uterine artery embolization (UAE).

Resting Energy Expenditure, Fetal Biometric Parameters by Ultrasound, and Birthweight in Chinese Pregnant Women With Gestational Diabetes Mellitus.

Objectives: To explore the relationships between resting energy expenditure (REE) according to indirect calorimetry, fetal biometric parameters by ultrasound, and birthweight in gestational diabetes mellitus (GDM).

Methods: Sixty-five women with GDM and 60 in the control group were enrolled. The REE, birthweight, and fetal biometric parameters according to ultrasound, including biparietal diameter, head circumference, abdominal circumference (AC), and femur length, were measured.

Application of contrast-enhanced ultrasound for scar pregnancy cases misdiagnosed as other diseases.

Objective: To demonstrate the feasibility of utilizing contrast-enhanced ultrasound (CEUS) in scar pregnancies misdiagnosed by transvaginal ultrasound (TVS).

Methods: CEUS was performed in three patients with clinically suspected abnormal pregnancy, and the diagnosis were inconclusive by TVS. Clinical manifestations and features of TVS and CEUS in these cases were analyzed.

The ultrasonic whirlpool sign combined with plasma d-dimer level in adnexal torsion.

Objectives: The whirlpool sign (WS) and plasma d-dimer are used as a sonographic marker and laboratory index for adnexal torsion (AT), respectively. The aim of this study was to evaluate whether their combination improved diagnostic efficiency of AT in patients presenting with a benign ovarian mass and abdominal pain and clinically suspected AT.

Materials And Methods: Fifty-four patients with clinically suspected AT with benign ovarian mass and abdominal pain were analyzed and divided into an AT group (n = 28) and control group (n = 26).

Fetal Hemodynamics and Fetal Growth Indices by Ultrasound in Late Pregnancy and Birth Weight in Gestational Diabetes Mellitus.

Background: The offspring of women with gestational diabetes mellitus (GDM) are prone to macrosomia. However, birth weight is difficult to be correctly estimated by ultrasound because of fetal asymmetric growth characteristics. This study aimed to investigate the correlations between fetal hemodynamics, fetal growth indices in late pregnancy, and birth weight in GDM.

[Diagnostic values of breast imaging and reporting data system and ultrasonic elastography for benign and malignant breast lesions].

Objective: To explore the diagnostic values of breast imaging and reporting data system (BI-RADS) and ultrasonic elastography (UE) for benign and malignant breast lesions.

Methods: A total of 122 breast lesions were studied with BI-RADS and UE scoring to compare the sensitivity and specificity according to the pathologic results. Receiver operating characteristic (ROC) curves were used to assess the diagnostic value of BI-RADS, UE and combination.

[The application value of BI-RADS lexicon and high-frequency CDFI scoring in differentiation of benign from malignant lesions of the breast].

Objective: To explore the diagnostic value with BI-RADS lexicon and high-frequency color doppler ultrasonic scoring for breast diseases.

Methods: A total of 108 breast lesions were studied with BI-RADS lexicon and high-frequency color doppler ultrasonic scoring, and compared with pathologic results. Calculated the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value.

Neck circumference positively related with central obesity, overweight, and metabolic syndrome in Chinese subjects with type 2 diabetes: Beijing Community Diabetes Study 4.

Objective: To investigate the association between neck circumference and central obesity, overweight, and metabolic syndrome in Chinese individuals with type 2 diabetes.

Research Design And Methods: A total of 3,182 diabetic subjects (aged 20-80 years) were recruited from 15 community health centers in Beijing using a multistage random sampling approach.

Results: Receiver operating characteristic analysis showed that the area under the curve for neck circumference and central obesity was 0.
