The Effects of Air Pollution on Ischemic Stroke Admission Rate / 전남의대학술지

The present study aimed to determine the relationship between the level of air pollutants and the rate of ischemic stroke (IS) admissions to hospitals. In this retrospective cross-sectional study, stroke admissions (January-March 2012 and 2013) to an emergency department and air pollution and meteorological data were gathered. The relationship between air pollutant levels and hospital admission rates were evaluated using the generalize additive model. In all 379 patients with IS were referred to the hospital (52.5% male; mean age 68.2+/-13.3 years). Both transient (p<0.001) and long-term (p<0.001) rises in CO level increases the risk of IS. Increased weekly (p<0.001) and monthly (p<0.001) average O3 levels amplifies this risk, while a transient increase in NO2 (p<0.001) and SO2 (p<0.001) levels has the same effect. Long-term changes in PM(10) (p<0.001) and PM(2.5) (p<0.001) also increase the risk of IS. The findings showed that the level of air pollutants directly correlates with the number of stroke admissions to the emergency department.

Prophylactic fluid therapy in crushed victims of Bam earthquake.

BACKGROUND: Acute kidney injury (AKI) is a severe and preventable problem of crushed earthquake victims. Early hydration therapy started before fully removing earthquake rubbles has been claimed to play a decisive role in AKI prevention, which saves the necessity of later dialysis. However, the extent, quality, and appropriateness of its know-how are controversial. METHODS: Processing clinical and paraclinical data gathered from Bam earthquake victims older than 15 years, we tried to determine correlations between the time of being under the rubbles (TUR), the level of serum creatine phosphokinase (CPK), the delayed onset of fluid therapy (DFT), and finally the volume of intravenous fluid received per day (VFR) with the formation of AKI and the need for dialysis. RESULTS: There is a direct and significant relation between the intensity of the trauma (TUR and CPK) and DFT with the occurrence of AKI and need for dialysis (P < .001). However, as the VFR increases, the occurrence of AKI and the need for dialysis significantly decrease (P = .005). Based on multivariate analysis, the occurrence of AKI and the need for dialysis are primarily affected by CPK, TUR, and VFR; and DFT has been dropped out. The analysis showed the preventive role of VFR more than 6 L in severe rhabdomyolysis patients and of at least 3 L in moderate ones in development of AKI and dialysis. CONCLUSIONS: In the severely rhabdomyolized patients (CPK ≥ 15,000), higher volumes of prophylactic fluid (VFR >6 L) are required, whereas in less-traumatized patients, lower volumes (3-6 L) would be effective.
