Should the septum be included in the assessment of right ventricular longitudinal strain? An ultrasound two-dimensional speckle-tracking stress study

AbstractRight ventricular longitudinal strain (RVLS) by 2D speckle-tracking echocardiography (2D-STE) is a useful parameter for assessing systolic function. However, the exact method to perform it is not well defined as some authors evaluate only free wall (FW) segments while others include all six RV segments. To compare the assessment of RVLS at rest and during exercise by these two approaches. Echocardiography was performed on 80 healthy subjects at rest and during exercise. The analysis consisted of standard and 2D-STE assessment of RV global and segmental strain tracing only RVFW and also tracing all six RV segments. At rest, RVLS could be assessed in 78 (feasibility 97.5%) subjects by both methods. However, during exercise, RVLS by RVFW method was  feasible in 67 (83.8%) as compared to 74 (92.5%) by RV6S approach. Both at rest and during exercise, RVLS values by the two methods showed excellent correlation (r =  >  0.90). However, RVLS values assessed by RV6S were lower (absolute values) than those by RVFW approach (RV6S vs. RVFW; rest: − 27.0 ± 3.9 vs. − 9.5 ± 3.9, p

In this study, we investigated the benefits of the electrocardiogram (ECG)-based R wave pulse wave index (ERWVI) for the diagnosis of CA. MATERIAL AND METHODS According to CA examinations by color Doppler ultrasound, patients were assigned to positive and negative groups. The ECG R wave-Pulse wave transit time (ERWPTT) was obtained by synchronously collecting ECG signals (R wave in ECG) and the time variations in maximum finger pulse oxygen (DOP) on the ECG monitor. RESULTS ERPWI was positively correlated with sex, age, BMI, diastolic/systolic blood pressure, fasting blood glucose, uric acid, cholesterol and triglyceride l...

We report a case of a 15-year-old girl who presented acute severe pain, a tenderness and a palpable mass in the left upper abdominal quadrant in a context of known ovarian cyst. An ultrasound described an ovarian cyst with uncertain vascularization. An urgent laparoscopy showed us a normal left ovary and revealed a very unusual combination of isolated fallopian tube torsion, with a big fallopian cyst and an elongated tube folded over the mesosigmoid. We performed a cystectomy without salpingectomy. This case reminds that paraadnexal and adnexal cysts can be found outside the pelvic area especially in children.

ConclusionsA nomenclature of 54 actions in Rheumatology was compiled. Biopsies (bone, sural nerve, synovial), inpatient visits, visits to the patient's home, infiltrations in children, and the preparation of the expert report were identified as the most complex actions. Musculoskeletal ultrasound is twice as complex as subsequent visits, capillaroscopy or bone densitometry.ResumenIntroducciónUna misión de la Sociedad Española de Reumatología es aportar las herramientas necesarias para alcanzar la excelencia asistencial. En la actualidad no existe una referencia que cuantifique la complejidad de ...

ConclusionsPseudoerosions are common at the dorsal metacarpal heads, lunate, triquetrum, and ulna, which should not be mistaken for true inflammatory erosions. The characteristic appearances of dorsal joint capsules and recesses should not be confused with synovial hypertrophy.

Nonetheless, olive leaves (containing thin branches), which are separated during olives cleaning in the mill, have received little attention. In this context, a multiple response optimization was performed to maximize at once the yield, total phenolic content, oleouropein and antioxidant activity obtained by ultrasound...

AbstractParathyroid surgery is frequently performed after at least two preoperative localisation studies, in addition to the use of intraoperative ioPTH. The key to performing a successful parathyroidectomy is reliant on the surgeon having an outstanding knowledge of parathyroid embryology and anatomy. With this, it is possible to undertake surgery with a simple neck ultrasound and without more expensive pre- and intraoperative localisation studies.

Authors: Patra A, Cai Y, Chatelain P, Sharma H, Drukker L, Papageorghiou A, Noble JA Abstract Recent automated medical image analysis methods have attained state-of-the-art performance but have relied on memory and compute-intensive deep learning models. Reducing model size without significant loss in performance metrics is crucial for time and memory-efficient automated image-based decision-making. Traditional deep learning based image analysis only uses expert knowledge in the form of manual annotations. Recently, there has been interest in introducing other forms of expert knowledge into deep learning architectu...
