On Estimating the Number of Vital Events in Demographic Surveys
Journal of the American Statistical Association, 1977Abstract An examination is made of the effectiveness of the Chandrasekar-Deming technique for estimating the number of vital events using both the registration (continuous recording) of events and a periodic retrospective survey. It is shown that, under a general model for response errors, the technique may produce estimates that are considerably ...

Estimators of vital events in dual-record systems
Journal of Applied Statistics, 2000Dual-record system estimation has been widely used to obtain vital events in the past. Because of the weakness of the statistical assumptions of the model, as well as the biases involved in the estimators, its use became limited. The proposed estimators for dual-record systems are based on further division of the cells of the original table.

The Interdependence of Vital Events: Twentieth-Century Indian Kerala
The Journal of Interdisciplinary History, 2000The parish records of Syrian Catholics and Latin Catholics in twentieth-century Kerala, India, can be used to assess the seasonal fluctuations and interdependence of such vital events as births, deaths, and marriages in the short run. That the effect of seasonality has been more pronounced among the Syrian Catholic community than among the Latin ...

Fish intake and risk of cardiovascular events: an analysis of the VITAL cohort
European Journal of Clinical Nutrition, 2022Dietary habits with fish consumption have been associated with a lower risk of cardiovascular (CV) disease, based on heterogenous observational studies. Current recommendations suggest eating at least 1-2 fish servings per week for CV prevention.We conducted a retrospective evaluation of a cohort study that enrolled a large primary prevention ...

MOVER: Medical Informatics Operating Room Vitals and Events Repository
2023AbstractArtificial Intelligence (AI) holds great promise for transforming the healthcare industry. However, despite its potential, AI is yet to see widespread deployment in clinical settings in significant part due to the lack of publicly available clinical data and the lack of transparency in the published AI algorithms.

Vital Auxiliaries — The Underrated Events
1984Auxiliary systems, such as instrument air, DC power and cooling water play an important part in keeping a nuclear power plant operating. This paper looks at failures which have occurred in these systems. A new technique for analyzing plant auxiliary systems to detect potential interactions between the auxiliary systems and other plant systems is ...

Prediction of Serious Adverse Events from Nighttime Vital Signs Values
2022 44th Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2022The period directly following surgery is critical for patients as they are at risk of infections and other types of complications, often summarized as severe adverse events (SAE). We hypothesize that impending complications might alter the circadian rhythm and, therefore, be detectable during the night before.

Frequency spectra of flow and volume events for forced vital capacity
Journal of Applied Physiology, 1982We determined the frequency content of forced expiratory flow-time (FT) and volume-time (VT) curves by a fast Fourier transform to determine the dynamic responses required of devices to reproduce these curves. We analyzed 304 FT and VT curves from 15 normal (N) subjects (ages 8– yr), 15 cystic fibrosis (CF) patients (ages 7–36 yr), and 9 smokers (S ...

Vitality and recurrent event risk in acute myocardial infarction survivors
European Journal of Cardiovascular Prevention & Rehabilitation, 2009Background Low vitality, characterized by fatigue and lack of energy, is common among survivors of acute myocardial infarction (AMI) and has been shown to be associated with increased risk of primary and secondary cardiac events. The goal of this study was to determine whether an association between vitality and recurrent cardiac events (nonfatal MI ...
