Abnormal heart rate characteristics of reduced variability and transient decelerations are
present early in the course of neonatal sepsis. To investigate the dynamics, we calculated …

We have applied principles of statistical signal processing and nonlinear dynamics to
analyze heart rate time series from premature newborn infants in order to assist in the early …

Publisher Summary This chapter presents Sample Entropy (SampEn) alogorithm as an
alternative method for entropy estimation in real world data. The chapter discusses the problems …

OBJECTIVE: To test the hypothesis that heart rate characteristics (HRC) monitoring improves
neonatal outcomes. STUDY DESIGN: We conducted a two-group, parallel, individually …

Entropy estimation is useful but difficult in short time series. For example, automated detection
of atrial fibrillation (AF) in very short heart beat interval time series would be useful in …

Significance: Quiescin sulfhydryl oxidase 1 (QSOX1) is an enzyme that oxidizes thiols during
protein folding, reducing molecular oxygen to hydrogen peroxide. Tumor cells may take …

Late-onset neonatal sepsis is a significant cause of morbidity and mortality, and early
detection could prove beneficial. Previously, we found that abnormal heart rate characteristics (…

Objective. Monitoring of regulated physiologic processes using physiomarkers such as heart
rate variability may be important in the early diagnosis of subacute, potentially catastrophic …

To test the hypothesis that heart rate characteristic (HRC) monitoring adds information to
clinical signs of illness in diagnosing neonatal sepsis, we prospectively recorded clinical data …

Objective: To determine the association of new-onset atrial fibrillation with outcomes,
including ICU length of stay and survival. Design: Retrospective cohort of ICU admissions. We …
