Shopping Smart With RFID Equipped Trolleys

RFID (RadioFrequency Identification) technology is an innovative measure that will make purchasing and shopping more convenient and comfortable. There would be no need to stand in long queues to pay the bill. Shoppers can be guided electronically to find desired products that are tagged with RFID chips and whose locations are tracked by RFID readers in the store (e.g., smart shelves or other reader systems). Smart shopping carts with electronic displays, in communication with a retail computer system, can display a shopping list downloaded by a shopper to identify a route to obtain the desired items. The smart cart, also equipped with RFID tags, can also verify the purchase of the items as they are placed in the cart and communicate with a billing system to automatically bill the shopper for the purchases

Predictors of inhospital mortality following out-of-hospital cardiac arrest: insights from a single-centre consecutive case series

PURPOSE OF THE STUDY: Out-of-hospital cardiac arrest (OHCA) has a poor prognosis despite bystander resuscitation and rapid transfer to hospital. Optimal management of patients after arrival to hospital continues to be contentious, especially the timing of emergency coronary angiography±revascularisation. Robust predictors of inhospital outcome would be of clinical value for initial decision-making.STUDY DESIGN: A retrospective analysis of consecutive patients who presented to a university hospital following OHCA over a 70-month period (2008-2013). Patients were identified from the emergency department electronic patient registration and coding system. For those patients who underwent emergency percutaneous coronary intervention, details were crosschecked with national databases.RESULTS: We identified 350 consecutive patients who were brought to our hospital following OHCA. Return of spontaneous circulation (ROSC) for &gt;20 min was achieved either before arrival or inhospital in 196 individuals. From the 350 subjects, 114 (32.6%) survived to hospital discharge. When sustained ROSC was achieved, either before or inhospital, survival to discharge was 58.2% (114 of 196). Non-shockable rhythm, absence of bystander cardiopulmonary resuscitation, 'downtime' &gt;15 min and initial pH ≤7.11 were predictors of inhospital death. 12% patients who underwent angiography in the presence of ST elevation had no acute coronary occlusion. 21% patients with acute coronary occlusion at angiography did not have ST elevation.CONCLUSIONS: In our cohort of patients with OHCA, those who achieve ROSC had a survival-to-discharge rate of 58.2%. We identified four predictors of inhospital death, which are readily available at the time of patient presentation. Reliance on ST elevation to decide about coronary angiography and revascularisation may be flawed. More data are required.</p
