The practical utility of psychometric scales for the assessment of the impact of posttraumatic scars on mental health.

Background: Scars are a natural consequence of the healing process, but with an impact on the psychological and social level for the individual, which can even lead to withdrawal and social stigmatization. We aimed to analyze the psychosocial impact determined by post-traumatic scars, using psychometric scales, to assess the effectiveness of the Mekereș' Psychosocial Internalization Scale (MPIS), and to identify relevant predictors of traumatic and surgical scar internalization. Methods: Our cohort included 293 participants, 149 women and 144 men, aged 18-64 years who were screened for scar characteristics and completed a set of psychological scales. We compared the results obtained in two subgroups: 153 subjects with posttraumatic scars and 140 with surgical scars. Results: Relevant predictors for posttraumatic scar internalization (R 2 = 0.721) are adaptation time, age of the occurrence and subjective appraisal, while for the depression, and hopelessness relevant predictors are the subjective appraisal of the scars and the posttraumatic quality of life. Conclusion: The psychological and social reporting of the aftermath of trauma, that has been followed by scar-ring, is an indicator of how a person will react and could indicate the susceptibility to psycho-pathology.

Assessment of arterial stiffness in patients with CKD stage 5 when initiating chronic hemodialysis for vascular access and for preventing cardiovascular events.

We consider that re-assessment of the vascular status is necessary, even mandatory, in patients with CKD when initiating dialysis because of two reasons:--assessment of vascular remodelling is important for establishing the artery-venous fistula as it can supply appreciative data on its success and duration;--vascular remodelling plays an important part in cardio-vascular pathology of patients dialysed, with the required consecutive prophylactic measures. In chronic kidney disease, calcium deposits at extra-skeletal level also affect the vessels, determining calcifications of both the vascular intima and media. Atherosclerosis and arteriosclerosis are present in patients with CKD and they contribute to diminishing the elasticity of the artery wall by vascular remodelling. Vascular remodelling determines thickening of the artery wall, respectively of the thickness of the arterial intima-media. Thus, arteries lose their elasticity, and the wall of the arterial tree wall turns stiff. Arterial stiffness is a process that precedes the development-proper of atherosclerosis, determined by cumulative exposure to various risk factors. Atherosclerosis is a focal process, in which indemne areas alternate with areas with atheroma plaques at intima level, and arteriosclerosis is a diffuse process located at the level of the arterial media. Non-invasive assessment of arterial stiffness can be achieved by analyzing pulse wave velocity and the augmentation index. We studied a group of 35 patients with chronic kidney insufficiency, CKD, stage 5, with an average age of 52.03 +/- 17.36 years, of whom 15 (43%) were females and 20 (57%) were males. The investigated parameters presented the following average values: PWV = 16.7 +/- 1.27 m/s; IMT = 1.63 +/- 0.18 mm; Aix = 36.14 +/- 9.98%; AAI = 0.78 +/- 0.2. The assessment of vascular stiffness in chronically dialysed patients offers better appreciation of vascular stiffness. Knowing the amplitude of the vascular remodelling process is of special importance for deciding the place and modality of performing the vascular access with regard to replacing the kidney function and to preventing cardiovascular events in dialysed patients.
