Cardiopulmonary resuscitation performed by trained providers and shorter time to emergency medical team arrival increased patients' survival rates in Istra County, Croatia: a retrospective study.

AIM: To assess the effect of the time for emergency medical services (EMS) arrival on resuscitation outcome in the transition period of the EMS system in Istra County. METHODS: This retrospective study analyzed the data from 1440 patients resuscitated between 2011 and 2017. The effect of demographic data, period of the year, time for EMS arrival, initial cardiopulmonary resuscitation (CPR) provider, initial cardiac rhythm, and airway management method on CPR outcome was assessed with multivariate logistic regression. RESULTS: Survivors were younger than non-survivors (median of 66 vs 70 years, P<0.001) and had shorter time for EMS arrival (median of 6 vs 8 min, P<0.001). The proportion of non-survivors was significantly higher when initial basic life support (BLS) was performed by bystanders without training (83.8%) or when no CPR was performed before EMS team arrival (87.3%) than when BLS was performed by medical professionals (66.8%) (P<0.001). Sex, airway management, and tourist season had no effect on CPR outcome. CONCLUSION: Since the time for arrival and level of CPR provider training showed a significant effect on CPR outcome, further organizational effort should be made to reduce the time for EMS arrival and increase the number of individuals trained in BLS.

The Role of CD44 and RHAMM in Endometrial (Endometrioid Type) Cancer: An Immunohistochemical Study.

Hyaluronan controls cell migration, differentiation, and proliferation, and it is involved in tumor invasion. The extracellular matrix containing hyaluronan regulates cell behavior via cell surface receptors such as CD44 and receptor for hyaluronan-mediated motility (RHAMM, CD168). We investigated the expression of CD44 and RHAMM in tissue samples of endometrial cancer and the relation of their expression with clinicopathologic parameters of patients. In order to evaluate the value of CD44 and RHAMM as prognostic factors, we investigated the relation of their expression with patients' survival. Our results demonstrated a statistically significant correlation with the depth of myometrial invasion, lymphovascular invasion (LVSI), The International Federation of Gynecology and Obstetrics stage of disease, and, in the case of RHAMM expression, a significant correlation with histologic tumor grade as well. CD44 expression was present in the cell membrane in all cases, but in a proportion of tumors in the cytoplasm as well. In this group of patients, we noticed a significantly greater number of cases with deeper myometrial invasion and LVSI. Finally, we sorted out the group of tumors with simultaneous strong CD44 and strong RHAMM expression, and found a statistically significant correlation with the depth of myometrial invasion and LVSI. Using an univariate analysis, we demonstrated that, in our sample of patients, CD44 expression showed a statistically significant influence on patients' 5-year survival. However, using a multivariate Cox regression analysis, neither CD44 nor RHAMM confirmed themselves as independent prognostic factors.
