This triggers compensatory mechanisms resulting in fetal vasoconstriction. Hemodynamic modelling has shown that the appearance of a second systolic peak P2, in addition to the main systolic peak P1, in the middle cerebral artery (MCA) Doppler waveform, thus creating a systolic M-sign, may indicate increased fetal vasoconstriction. Hence, the M-sign could be expected in twins with TTTS. The Quintero staging system has been used to stage TTTS. However, TTTS does not always develop in line with the Quintero stages and/or the criteria are not always fulfilled. This study investigates whether the M-sign could be an additional TTTS criterion indicating significant imbalance between the fetuses.38 women who underwent fetoscopic laser coagulation (FLC) for TTTS were included. The MCA Doppler waveforms were retrospectively analyzed for the presence of an M-sign. We subdivided the M-signs into 2 groups: Group A: the main systolic peak P1 dominates P2, i.e., P2/P1 <1; Group B: P2 exceeds P1: P2/P1 >1.Before FLC, an M-sign was found in 17/38 (45%) pregnancies. Both twins showed M-signs in 9 pregnancies, only the recipient in 6, and only the donor in 2. In 6 (35%) fetuses, an M-sign appeared before the Quintero criteria were fulfilled. Postoperatively, M-signs disappeared in all cases.The appearance of an M-sign could be an additional marker of cardiovascular imbalance in monochorionic-diamniotic twins with developing or already present TTTS. Postoperative M-sign disappearance may indicate fetal recovery.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144210060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, 4 rheumatologist ultrasonographers identified on B-mode imaging the tissue patterns of the structures in the dorsal aspect of the MCPJ in fresh-frozen cadaveric hands. In the second step, 2 anatomists performed dissections on fresh-frozen and embalmed cadaveric hands to characterize the components of the dorsal MCPJ, providing anatomy-based feedback to aid ultrasound tissue interpretation. Histological and immunohistochemical analyses were also conducted on selected dorsal MCPJ tissues. In the third step, the anatomy and histology-based knowledge were applied to identify and evaluate these structures in healthy subjects using B-mode and Doppler mode ultrasound.Ultrasound examination of the cadaveric hands identified the key dorsal MCPJ structures, including the extensor tendon, joint capsule, dorsal plate, synovial recesses, and metacarpal head cartilage. Anatomical and histological analyses further characterized these structures, enhancing their identification in healthy subjects.

Since cardiac function and size may also be altered, we hypothesized that abnormal cardiac function may contribute in their impaired brain development. The aim of this study is to evaluate if cardiac dimensions and function correlate with brain development in CDH fetuses. Materials and Methods All fetuses with left CDH who underwent ultrasound evaluation of cardiac function and brain development between 2018 and 2023 were included. We analyzed the correlation between cardiac size and function parameters with the parieto-occipital (POF) and Sylvian (SF) fissures and insular depth (ID) at two gestation periods (GP). Cardiac and brain anatomical measures were corrected for head circumference, cardiac function parameters were corrected for estimated fetal weight or GA. Correlations were analyzed using Pearson test, p value <0.05 was considered significant. Results 24 fetuses with left CDH were included. Between 20 and 24 weeks gestation, POF, SF, and ID were significantly correlated with aortic flow. Right ventricle E/A was significantly correlated with POF and SF, with a trend toward correlation with ID, approaching the threshold of significance. In this GP, ID was also significantly correlated to the Left ventricle area, E/A, and E', S' and A'. Most correlations were lost in next GP. Conclusions Between 20 and 24 weeks gestation, brain development of fetuses with CDH is significantly correlated with cardiac function. Most of these correlations were lost at 25-28 weeks' gestation.

Both parameters were correlated with each other and with the duration of the disease, TCNS, and HbA1c. The CSA cut-off value of both tibial and median nerves to detect DPN in patients was 13.5 mm2, meanwhile, the SWE cut-off values were 68.5 and 61.5 KPa, respectively. SWE showed a higher AUC than CSA for the prediction of DPN.Measurement of the CSA and stiffness of the peripheral nerves could be a reliable tool for early detection of DPN.

Of the 150 studies identified, 6 met the inclusion criteria. Among the cases of non-dilated ventricular asymmetry, 36.8-46.2% progressed to ventriculomegaly on follow-up by neurosonography or magnetic resonance imaging. Additional findings in the central nervous system were observed in 5.5-10.5% of cases, while 7.6% had additional fetal body findings. Abnormal genetic findings were present in 5.1% of cases. Postnatal follow-up indicated no abnormal developmental findings during the first year of life. By the age of 9-11 years, lower writing speed was observed, yet verbal fluency scores were higher than in the general population. In conclusion, non-dilated ventricular asymmetry in fetuses showed the potential for progression to ventriculomegaly, and linkage to genetic abnormalities.

A prerequisite for reliable and Europe-wide comparable diagnostic reliability of PoCUS performed by primary care physicians is high-quality training limited to relevant, frequently encountered PoCUS applications that are easy to learn and master. A European Federation of Societies for Ultrasound in Medicine (EFSUMB) task force commenced with a brainstorming exercise to identify all possible ultrasound examinations that could be performed in primary care. A three-stage Delphi process was launched. Delphi panellists were 95 primary care physicians from 28 European countries with more than two years of experience using and teaching ultrasound. Solely focusing on the complexity of performing PoCUS, panellists stepwise reduced the brainstorming list to a basic core curriculum intended for primary care frontline physicians including 40 diagnostic PoCUS examinations within 13 different anatomical areas and no ultrasound-guided procedures. A 75% cut-off was used for agreement. Despite the great heterogeneity of the Delphi panel representing different views and contexts from across Europe, kappa statistics showed substantial or moderate agreement across Delphi round two and three for 85% of the 40 diagnostic PoCUS applications. The results of this study offer guidance for EFSUMB to establish training recommendations for the basic core curriculum that can be adapted to the needs of different regions of Europe and thus create a basis for PoCUS to become a reliable diagnostic service in primary care across Europe, based on common quality standards.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144003907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the most commonly used examination method, the accuracy of pelvic floor ultrasound diagnosis is influenced by subjective factors such as doctor experience and fatigue level, making it challenging to achieve high accuracy, consistency, and repeatability of diagnosis. This study aims to propose a high-precision and fully automatic cystocele evaluation method based on pelvic floor ultrasound video images.Materials and methods: This study retrospectively collected pelvic floor ultrasound images of 158 female G1P1 (first gestation and first parturition) patients from 2020 to 2024. According to the the ultrasound diagnosis of two senior doctors as the standard, 81 cystoceles and 66 non-cystocele patients were enrolled. Firstly, the ResNet34-UNet was used for automatic urethra segmentation. Then, key points were generated based on the automatically extracted urethra centerline. Features such as urethral key point displacement, urethral curvature change, and urethral inclination angles and their change were extracted for patients between rest and maximum Valsalva states. The support vector machine (SVM) classification model was used for cystocele prediction.Results: This study constructed two classification models to predict cystocele. One extracted the above features based on the automatic urethra segmention, while the other extracted them based on the doctor-annotated urethra. The experimental results show that both models have achieved good prediction results, with AUCs of 91.37% and 98.58%, respectively. Model performance based on the urethral image delineated by the doctor is better, with an AUC improvement of 7.21% on the independent test set.Conclusion: The proposed method can achieve high-precision, repeatable, fully automatic quantitative cystocele evaluation in pelvic floor ultrasound examinations.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144056949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
