Objective: To quantify how the first public announcement of confirmed coronavirus disease 2019 (COVID-19) in Italy affected a metropolitan region's emergency medical services (EMS) call volume and how rapid introduction of alternative procedures at the public safety answering point (PSAP) managed system resources.
Methods: PSAP processes were modified over several days including (1) referral of non-ill callers to public health information call centers; (2) algorithms for detection, isolation, or hospitalization of suspected COVID-19 patients; and (3) specialized medical teams sent to the PSAP for triage and case management, including ambulance dispatches or alternative dispositions. Call volumes, ambulance dispatches, and response intervals for the 2 weeks after announcement were compared to 2017-2019 data and the week before.
We consider a zero-temperature one-dimensional system of bosons interacting via the soft-shoulder potential in the continuum, typical of dressed Rydberg gases. We employ quantum Monte Carlo simulations, which allow for the exact calculation of imaginary-time correlations, and a stochastic analytic continuation method, to extract the dynamical structure factor. At finite densities, in the weakly interacting homogeneous regime, a rotonic spectrum marks the tendency to clustering.

However, just an overall number of about 40 cases have been previously reported. Giant occipital meningocele has been described only in three newborns.

Study Design: Included in the study were all consecutive euploid non-malformed singleton fetuses with accurate dating diagnosed as growth restricted (sonographic abdominal circumference <10th percentile) between January 1995 and December 1998 and who were delivered at > or =34 weeks. Delivery was expedited for biophysical profile 6 or less with nonreactive nonstress test, preeclampsia, oligohydramnios, absent fetal growth over 2 weeks, absent or reversed diastolic flow in the umbilical artery (UA), or UA pulsatility index (PI) greater than the 95th percentile after 37 weeks.
