A reconfigurable, wearable, wireless ECG system.

New emerging concepts as "wireless hospital", "mobile healthcare" or "wearable telemonitoring" require the development of bio-signal acquisition devices to be easily integrated into the clinical routine. In this work, we present a new system for Electrocardiogram (ECG) acquisition and its processing, with wireless transmission on demand (either the complete ECG or only one alarm message, just in case a pathological heart rate detected). Size and power consumption are optimized in order to provide mobility and comfort to the patient.

Postoperative changes in serum interleukin-2 concentrations.

Objective: To evaluate the postoperative changes in circulating interleukin-2 (IL-2) concentration according to the severity of the surgical injury and other postoperative variables that could influence IL-2 production.

Design: Prospective observational study.

Setting: University hospital, Italy.
