After screening by ASA grade III or IV, 248 patients who met the inclusion criteria were identified, involving 104 open and 144 laparoscopic rectal resections. The distribution of the Charlson Comorbidity Index was similar between the two groups. Compared with open rectal resection, laparoscopic resection had a significantly lower total complication rate (P smaller than .0001), lower pain rate (P=.0002),

and lower blood loss (P smaller than .0001). It is notable that the two groups of patients had no significant Selleckchem GSK1904529A difference in cardiac and pulmonary complication rates. Thus, these data showed that the laparoscopic group for rectal cancer could provide short-term outcomes similar to those of their open resection counterparts with high operative risk. The 5-year actuarial survival rates were 0.8361 and 0.8119 in the laparoscopic and open groups for stage I/II (difference not significant), as was the 5-year overall survival rate in stage III/IV (P=.0548). In patients with preoperative cardiovascular or pulmonary disease, the 5-year survival curves were significantly different (P=.0165 and P=.0210), respectively. The cost per patient did not differ between the two procedures. The results of this analysis demonstrate the potential advantages of laparoscopic rectal cancer resection for high-risk patients, although a randomized

controlled trial should be conducted to confirm the findings of the present study.”
“Time waveform see more analysis is an important tool in biomedical engineering. Common signal analysis methods use scalar products and predefined signals to construct a representation for the signal of interest. Here we use a novel method to represent and analyze signals. The method relies on the Schrodinger equation and uses its eigenvalues and eigenfunctions for the representation and analysis of a given signal. We extend this so called semi-classical signal analysis method, apply it to an ECG recording and discuss its properties.”
“Aim of our study

was to compare the diagnostic performance of F-18-FDG PET/CT and MR imaging (MRI) in the detection of liver metastases in patients with adenocarcinomas of the gastrointestinal tract. A total of 49 patients with adenocarcinomas of the gastrointestinal tract who had undergone F-18-FDG PET/CT and MRI of the liver were included in this study. The MRI protocol included diffusion-weighted imaging and dynamic contrast-enhanced MR imaging after intravenous injection of Gd-DTPA. PET and MR images were analyzed by two experienced radiologists. Imaging results were correlated with histopathological findings or imaging follow-up as available. Sensitivities of both modalities were compared using McNemar Test. Receiver operating characteristic (ROC) curves were calculated to determine the diagnostic performance in correctly identifying liver metastases. A total of 151 metastases were confirmed.
