Background: A proportion of patients with acute pancreatitis develop severe organ dysfunction requiring admittance in an intensive care unit. Patient characteristics associated with ICU admittance were evaluated in this consecutive series of patients. Methods: The clinical course of patients with first attack of acute pancreatitis in urban Norway between 01.01.1996 and 31.12.2006 was reviewed. Patient characteristics, comorbidity, pre hospital delay and likely aetiology of acute pancreatitis were analysed as risk factors for ICU admittance. Results: This study includes 565 patients, 299 women and 266 men (p = 0.089), with a median age of 60 years (range: 17 - 98). 50 (9%) of the patients were admitted to the ICU. Men were more at risk than women for ICU admittance (OR 2.34;95% CI: 1.27 - 4.32). Patients with alcohol associated pancreatitis (OR 5.94;95%, CI: 2.61 - 13.53), miscellaneous aetiologies (OR: 2.81, 95% CI: 1.02 - 7.73) and non-assessed aetiology (OR: 2.71, 95%, CI: 1.26 - 5.82) were more at risk of ICU admittance than patients with bile stones associated pancreatitis. Pre hospital delay increased the risk of ICU admittance amongst patients with alcohol associated pancreatitis (OR: 4.23;95%, CI: 1.11 - 16.18). Two comorbid conditions conveyed increased risk (OR: 8.78;95%, CI: 1.87 - 41.22). The case fatality rate was 24% in the ICU and 1.6% in the ward (OR 20.01, 95% CI: 7.71 - 51.93). Conclusions: Aetiology of acute pancreatitis, especially alcohol, pre-hospital delay and male gender are associated with increased of risk of ICU admittance and increased fatality rate during first attack of AP.

A set of forty-three hetero-junction CNTs, made of forty-four homogeneous carbon nanotubes of different chiralities and configurations with all possible hetero-connection types, were numerically simulated, based on the finite element method in a commercial finite element software and their Young's and shear moduli, and critical buckling loads were obtained and evaluated under the tensile, torsional and buckling loads with an assumption of linear elastic deformation and also compared with each other. The comparison of the linear elastic behavior of hetero-junction CNTs and their corresponding fundamental tubes revealed that the size, type of the connection, and the bending angle in the structure of hetero-junction CNTs considerably influences the mechanical properties of these hetero-structures. It was also discovered that the Stone-Wales defect leads to lower elastic and torsional strength of hetero-junction CNTs when compared to homogeneous CNTs. However, the buckling strength of the hetero-junction CNTs was found to lie in the range of the buckling strength of their corresponding fundamental tubes. It was also determined that the shear modulus of hetero-junction carbon nanotubes generally tends to be closer to the shear modulus of their wider fundamental tubes while critical buckling loads of these heterostructures seem to be closer to critical buckling loads of their thinner fundamental tubes. The evaluation of the elastic properties of hetero-junction carbon nanotubes showed that among the hetero-junction models, those with armchair-armchair and zigzag-zigzag kinks have the highest elastic modulus while the models with armchair-zigzag connections show the lowest elastic stiffness. The results from torsion tests also revealed the fact that zigzag-zigzag and armchair-zigzag hetero-junction carbon nanotubes have the highest and the lowest shear modulus, respectively. Finally, it was observed that the highest critical buckling loads belong to armchair-armchair heter
