The physiological changes of pregnancy may predispose females to develop sleep-disordered breathing (SDB) or protect against it. Studies evaluating outcomes of SDB symptoms in pregnancy are scarce. The goal of this study was to evaluate the prevalence of SDB symptoms in pregnancy and their relationship with pregnancy and neonatal outcomes. A cross-sectional survey of randomly selected immediate...
Question: What are the identifiable risk factors for retained foreign bodies in surgical patients? Design: Case–control study. Setting: A malpractice insurance agency and 10 hospitals in the state of Massachusetts from January 1, 1985 to January 1, 2001. Participants: Fifty-four patients with a total of 61 retained foreign bodies, and 235 control patients. Assessment of risk factors: Risk facto...
in this paper a new algorithm has been proposed to predict unplanned islanding. To predict unplanned islanding, rotor angle and speed time series have been used. Times of fault occurrence and clearance are estimated using monitoring system response based on the variation of phasor measure data. The estimated times of fault occurrence and clearance are used to determine suitable calculation wind...
OBJECTIVES To determine the incidence of outcomes, unanticipated admissions and cancellations in patients operated in an Ambulatory surgery unit, and to establish the relationships with their body mass index (BMI). SUBJECTS AND METHODS An observational descriptive prospective study was conducted in the Ambulatory surgery unit of the University Hospital Virgen del Rocío of Seville, on ASA I or...
BACKGROUND AND OBJECTIVES Unplanned extubation can be a significant event that places the patient at risk for adverse events. Our goal was to reduce unplanned extubations to <1 unplanned extubation per 100 patient-intubated days. METHODS All unplanned extubations in the NICU beginning in October 2009 were audited. Data collected included time of day, patient weight, and patient care activity ...
BACKGROUND AND OBJECTIVE Appropriate patient placement at the time of admission to avoid unplanned transfers to the ICU and codes outside of the ICU is an important safety goal for many institutions. The objective of this study was to determine if the overall rate of unplanned ICU transfers within 12 hours of admission to the inpatient medical/surgical unit was higher for direct admissions comp...
BACKGROUND Rehospitalizations (RHs) after ST-elevation myocardial infarction carry a high economic burden and may deteriorate quality of life. Characterizing patients at higher risk may allow the design of preventive measures. We studied the frequency, reasons, and predictors for unplanned cardiac and noncardiac RHs in ST-elevation myocardial infarction patients undergoing primary percutaneous ...
The dilution of jet engine exhaust in the plume behind cruising aircraft is determined from measured plume properties. The data set includes in situ measurements of CO 2 , NO, NO y , SO 2 , H 2 O, temperature, and contrail diameters behind subsonic and supersonic aircraft in the upper troposphere and lower stratosphere, for plume ages of seconds to hours. The set of data is extended into the ra...
