Influence of hosting the world’s most popular football competition on Response and Transport Time of Ground Emergency Ambulances in Qatar
منشور في 2024"…Contrary to expectations, response and transport times were at their shortest during the tournament compared to prior years despite the increased population. This can probably be explained by the measures put in place by the Police Traffic Department to minimise the number of vehicles on the roads, promoting the use of public transport which was free to match ticket holders, closure of many roads around Doha and stadiums, and an increase of the size of the ambulance fleet and workforce enabling more ambulances to respond to emergency calls.…"

Effectiveness of Positron Emission Tomography for Predicting Chemotherapy Response in Colorectal Cancer Liver Metastases
منشور في 2010"…For example, a few years ago an extrahepatic metastasis effectively eliminated surgical resection, but a combination of chemotherapeutic options and surgical techniques has expanded the indications for resection and increased the population of patients who may benefit.1,2 Neoadjuvant chemotherapy has increased the resectability rate by 11% to 37%.1 Unfortunately, greater than 80% of patients undergoing hepatic resection will have recurrences, mostly within the first 2 years.2 Nonetheless, the only hope for cure is resection, and prior surgical dogma based on the number of lesions, size of the tumor-free resection margin, and presence of resectable extrahepatic disease must be questioned.3- 5 The current standard approach to surgical planning is contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) for specific tumor characteristics or contraindications to CT.6 Several series showed that focal extrahepatic disease, an isolated pulmonary lesion, can be safely resected, with 5-year survival rates of 29% to 58%.7,8 In 1 series,7 17 of 30 patients required 3 or more resections. …"
