Article Title: Missed Down Syndrome Cases after First Trimester False-Negative Screening—Lessons to be Learned

doi: 10.3390/medicina56040199

Figure Lengend Snippet: The seven cases with DS and false-positive risk calculation after first-trimester ultrasound risk assessment.

Article Snippet: We conducted traditional first-trimester screening, using maternal age at the time of measurement, of standardized ultrasound parameters (NT, nasal bone, DV, tricuspid flow, and fetal heart rate) and MoM values for biochemical markers (free beta-hCG level and serum PAPP-A), using ASTRAIA software.

Article Title: Chronic vagus nerve stimulation is associated with multi-year improvement in intrinsic heart rate recovery and left ventricular ejection fraction in ANTHEM-HF

doi: 10.1007/s10286-021-00780-y

Figure Lengend Snippet: Comparison of the pattern of intrinsic heart rate recovery (HRR) based on spontaneous heart rate changes in ambulatory electrocardiograms (AECGs). Essentially, an initial heart rate (HR) maximum point (HR peak ) is identified, and subsequent HRR to the final heart rate (HR trough ) is fit to a mono-exponential decay with time constant of recovery (tau), based on a sequence of smoothed and decaying heart rate maxima and minima, as described in detail in the methods section. The x -axis represents a portion of the 24 h monitoring period, and the y -axis displays the patient’s heart rate. In a representative patient, VNS reduced tau by 40.6%, from 18.0 s at screening (upper panel) to 10.7 s at 36 months of therapy (lower panel)

Article Title: Impaired autonomic function in adolescents born preterm

doi: 10.14814/phy2.13620

Figure Lengend Snippet: Resting heart rate variability. Standard deviation of R‐R intervals, SDRR. B. Root means squared of successive differences, RMSSD. Percentage of differences higher than 50 msec in RR intervals, pRR50. Box and whisker plots describe the mean of the data for each group, with bars showing the max and min values. Data are from 13 control and 12 preterm subjects.

Article Snippet: The frequency‐domain variables were determined offline using the heart rate variability software package by PowerLab and was analyzed via LabChart software (ADInstruments, Inc., Colorado Springs, CO).

Techniques: Standard Deviation, Whisker Assay, Control
