Abstract

DM), Chronic Obstructive Pulmonary Disease (COPD), Coronary Artery Disease (CAD), and Hypertension (HTN) were assessed with respect to their incidence in the group that was readmitted and the group that was not. Results: The cohort consisted of 155 women and 133 men with a mean age of 59.0 ± 15.2 yr. One hundred fifty seven patients (57%) required ICU readmission (118 were discharged elsewhere, 13 expired). The mean CCI for ICU readmissions was not significantly different compared to those not readmitted (5.0 ± 2.9 vs. 4.6 ± 2.7, p = 0.22). Further subgroup analysis of those with HTN (67.3%), DM (52.7%), COPD (34.2%), and CAD (23.6%) was performed and demonstrated that patients who required ICU readmission had a higher incidence of these specific comorbidities compared to those who did not (mean number of comorbidities 1.9 ± 1.2 vs. 1.6 ± 1.0, p = 0.04). Conclusions: Comorbidity burden as represented by CCI does not strongly correlate with discharge disposition in survivors of critical illness. However, patients who are readmitted to the ICU have a greater total number of specific comorbidities. Thus, physicians should be mindful of the increased likelihood of readmission when DM, HTN, COPD, or CAD are present in ICU survivors.

Current key options for management of industrial alkaline waste of alumina production (red mud)

“…If RM is discharged into deep sea, sea water is contaminated with toxic components, harmful metals and metalloids: As, Pb, Hg, Cd, Cr, Ni, Mo, V, etc. ; radioactive elements: 238 U, 232 Th and their decay products; as well as fine and colloidal particles such as aluminum and magnesium compounds, leading to an increase in turbidity of the sea [8]. In the case of lagooning, alkaline (pH ~ 10-13) RM slurry is directly pumped into specially equipped ground-based filler sludge ponds.…”
