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.

Seasonally of vital events in a pacific island population
Biodemography and Social Biology, 1991Analyses of vital data derived from a family record register for the native population of Guam reveal significant variations in births, deaths, and marriages over the period 1901-41. Although lacking marked photoperiod or temperature changes of temperate zones, the tropical island is subject to marked seasonal differences in rainfall characteristic of ...

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 ...

Meta-Analysis of Relation of Vital Exhaustion to Cardiovascular Disease Events
The American Journal of Cardiology, 2017To assess the net impact of vital exhaustion on cardiovascular events and all-cause mortality, we conducted a systematic search of PubMed, EMBASE, and PsychINFO (through April 2016) to identify all studies which investigated the relation between vital exhaustion (VE) and health outcomes.

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 ...

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 ...

Automatic recognition of significant events in the vital signs of neonatal infants
Computers and Biomedical Research, 1979Abstract A method is presented which automatically detects and reports on some of the commonly described irregularities in the vital signs of neonatal infants. The program is compact and may be used on-line in a minicomputer system which monitors these infants.

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.

When to Be a Nonconformist Entrepreneur? Organizational Responses to Vital Events
SSRN Electronic Journal, 2012Salient successes and failures among organizations, such as spectacular venture capital investments or agonizing bankruptcies, affect consensus beliefs about the viability of particular markets. We argue that collective sense making in the wake of such vital events triggers overreactions in shared perceptions of particular markets.

Access and accessibility to Canadian vital event records
1993The transfer of copies of vital event records into a government archives repository is necessary not only to ensure their ongoing preservation, but also to provide access and accessibility to them for all researchers in an appropriate setting. At present all vital event records gatekeepers in Canada, except two, do not have in place a system providing ...
