Fetal Cardiac Function Evaluation

The study population comprises 50 pregnant women between 20 and 28 gestational weeks, who underwent transabdominal echocardiography in the Department of Ultrasound, The First Maternal and Infant Health Care Hospital, Shanghai, China, between March 2015 and December 2015. All fetuses were with normal cardiac functions (the stroke volume (SV): 0.23~1.21 ml, the ejection fraction (EF): 0.38~0.85). All echocardiographic examinations were performed with a GE VOLUSON 730 system (General Electric Healthcare, Milwaukee, WI, USA) with a RAB6-1 probe using the spatiotemporal image correlation (STIC) imaging mode. Each echocardiographic sequence spanned a cardiac cycle and contained 40 views. For the following analysis and comparisons, 3DE data was stored for each view, in which 2DE in 4-chamber view was extracted from the 3DE by an experienced doctor. The LV border for each 2DE four-chamber view was also delineated by the experienced doctor.
The study protocol was approved by the local ethics committees, and informed consent was obtained from all patients.

All examinations were performed using a Philips IU22, IU elite, or HD11 system (Philips, Best, The Netherlands), a GE E8 or Voluson 730 system (GE Healthcare, Waukesha, WI), a Sequoia 512 system (Siemens Healthineers, German), or an Esaote Mylab (Esaote, Italy). Transducers included abdominal convex array probes with a frequency of 3.5 to 5.0 MHz and endovaginal probes with a frequency of 5.0 to 7.0 MHz.

Embryo Transfer Protocol for IVF

Check if the same lab product or an alternative is used in the 5 most similar protocols

Between one and three embryos were transferred under transabdominal ultrasound guidance using the Voluson® 730 system (GE Healthcare) 2, 3 or 5 days after oocyte retrieval, depending on the number and quality of the embryos available.
The Gardner and Schoolcraft blastocyst grading system was adopted (Gardner and Schoolcraft, 1999) . According to this classification, a blastocyst of grade 3CC (when the blastocele completely fills the embryo, with very few cells in both the inner cell mass and the trophectoderm), was considered to be the cut-off for embryo freezing. Surplus blastocysts of grade 3CC or higher that showed no signs of degeneration were cryopreserved on day 5 or 6 after fertilization (Gardner and Schoolcraft, 1999) .
The luteal phase was supported with 400 mg progesterone pessaries (Cyclogest®; Actavis UK Ltd, Barnstaple, Devon, UK) twice daily commencing on the day of oocyte retrieval and continuing until 8 weeks' gestation. A urine pregnancy test using a commercially available kit was performed 16 days after oocyte retrieval to confirm a pregnancy. A clinical pregnancy was defined as the detection of a fetal heartbeat using ultrasound performed 3-4 weeks after a positive pregnancy test. A live birth was defined as delivery of a live baby beyond 24 weeks' gestation.

Fetal Sonographic Examination Protocol

All patients were scanned in a semi recumbent position by the same sonographer with the help of Voluson 730 system (RAB 2-5 MHz transducer; GE Healthcare Austria, Tiefenbach, Austria). Same instrumental settings were used in all cases ('Obstetrics/2-3 trimester' in 2D mode). An initial two-dimensional conventional examination provided data about fetal position, body movements and fetal heart rate, placental localization, insertion of umbilical cord, the volume of amniotic fluid and fetal biometry according to the formula B of Hadlock [13] , followed by two-dimensional color Doppler investigation of uterine arteries [14] , where pulsatility index (PI) was measured as well [15] .

Comparison of DCIS Imaging Modalities

Check if the same lab product or an alternative is used in the 5 most similar protocols

This retrospective analysis reviewed the US and mammographic data from 173 patients with DCIS at the University of Cologne -Department of Senology between the years 2007 and 2010. Of the 173 patients, 34 fulfilled the following requirements: unilateral, pure DCIS, no invasive component, no prior breast cancer nor other malignancy, having undergone mammography as well as bilateral breast US evaluation, no prior chemotherapy or radiation therapy. Identifying patient data was only available to the reviewing physician. Surgical techniques included breastconserving surgery (BCS), mastectomy and skin-sparing or subcutaneous mastectomy (SSM). The average patient age was 57.7 years. Both pre-and postmenopausal patients were evaluated. For the purpose of this work, it was considered to be beneficial to patients if tumor size were overestimated rather than underestimated, as this might require revision surgery due to a R1 resection.
Diagnostic equipment. Mammography was performed using a Selenia Dimensions mammography system (Hologic, Bedford, MA, USA). US was performed by personnel qualified to at least DEGUM Level 2 (Deutsche Gesellschaft für Ultraschall in der Medizin e.V.) using Voluson E8 and a Voluson 730 system (GE Healthcare, Little Chalfont, UK).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
