Aim: Changes in the pH of chronic wounds can inhibit the optimal activity of various enzymes in the wound environment, thereby delaying wound healing. The aim of the present study is to monitor the effect of limited access dressing (LAD) on the pH on the surface of chronic wounds. Methods: A total of 140 patients with chronic wounds of more than 4 weeks duration were divided into two groups by ...

to standardize the neuroticism, extroversion, openness personality inventory (neo pi-r), the persian version of the test was prepared and administered to a group of shiraz residents (n = 502). the means and standard deviations for the five main scales and the total 30 subscales are reporteed in this paper. the results of analysis for internal consistency and correlation coefficient showed high ...

In this paper, the high-dimensional sparse linear regression model is considered, where the overall number of variables is larger than the number of observations. We investigate the L1 penalized least absolute deviation method. Different from most of other methods, the L1 penalized LAD method does not need any knowledge of standard deviation of the noises or any moment assumptions of the noises...

Critical care environments are complex and dynamic. To adapt to such environments, clinicians may be required to make alterations to their workflows resulting in deviations from standard procedures. In this work, deviations from standards in trauma critical care are studied. Thirty trauma cases were observed in a Level 1 trauma center. Activities tracked were compared to the Advance Trauma Life...
