AIM To study the effect of enteral feeding on splanchnic blood flow velocity in preterm infants. METHOD Coeliac axis and superior mesenteric artery (SMA) blood flow velocity were measured longitudinally in a cohort of 61 babies using Doppler ultrasound. RESULTS Babies fed 1 hourly had significantly higher preprandial SMA peak systolic velocity (PSV) than those fed 3 hourly (70 vs 53 cm/s). ...

There has been debate in the field of nursing regarding the benefit of performing structured hourly rounds on patients. Many hospitals, if not already using the system, are beginning to implement structured hourly rounds in their institutions. The decision for hospitals to implement hourly rounding as part of patient care is primarily driven by patient satisfaction scores and efforts to increas...

The Mechanical Turk crowdsourcing platform currently fails to provide the most basic piece of information to enable workers to make informed decisions about which tasks to undertake: what is the expected hourly pay? Mechanical Turk advertises a reward amount per assignment, but does not give any indication of how long each assignment will take. We have developed a browser plugin that tracks the...

We study the volatility of the MIB30–stock–index high–frequency data from November 28, 1994 through September 15, 1995. Our aim is to empirically characterize the volatility random walk in the framework of continuous–time finance. To this end, we compute the index volatility by means of the log–return standard deviation. We choose an hourly time window in order to investigate intraday propertie...

Professional members of the National Academy of Neuropsychology (NAN) completed a survey focusing on clinicians' time requirements for activities, number of yearly claims to funding sources, average reimbursement rates, reimbursement rates associated with specific current procedural terminology (CPT) codes, managed care tolerance, hourly reimbursement rates, and other relevant practice issues s...

We develop and evaluate time-series models of call volume to the emergency medical service of a major Canadian city. Our objective is to offer simple and effective models that could be used for realistic simulation of the system and for forecasting daily and hourly call volumes. Notable features of the analyzed time series are: a positive trend, daily, weekly, and yearly seasonal cycles, specia...

1. The present study sought to determine the possible existence of a pool of proteins which turn over with life-time kinetics. The pattern of enrichment of ammonia and urea in hourly samples of urine was determined in normal adults to whom oral doses of [15N]glycine were given hourly for 36 h. The subjects received hourly meals throughout, and in six the study commenced at 06.00 hours, in five ...
