Background and Aim: Kidney transplantation is the treatment of choice in most patients with kidney disease. It is a surgical operation in which a person’s kidney with chronic failure is replaced with a healthy kidney. The present study was conducted with the aim of estimating the survival probability of a transplanted kidney in patients with chronic kidney failure in Zahedan city, Iran. Materials and Methods: This was a descriptive-analytical retrospective cohort study using the survival analysis method carried out in 2020. The sample size was estimated to be 211 patients. Data were analyzed with SPSS.VER22 software using descriptive tests, the Kaplan-Meier method and the Cox proportional hazards model of survival. Results: The data obtained showed that in general 45 (21.3%) clients had been rejected. In the multiple logistic regression model of kidney transplantation several variables, including survival time, patient survival variables, marital status, donor status, blood pressure and diabetes remained in the model (P<0.05). Further analysis of the data revealed that in the kidney disease patients with transplant survival in Zahedan city, only donor status variables, high blood pressure and diabetes remained in the final multiple Cox regression model. Conclusion: Based on the results, it can be said that the probability of survival of kidney disease patients is independent of the type of donor and the characteristics of the recipient, which indicates the evolution of kidney transplant management over the past few years; dialysis before kidney transplantation also has an effect on the probability of survival. These factors can help to increase the probability of kidney transplant survival. [ABSTRACT FROM AUTHOR]

The brain noradrenergic system supplies the neurotransmitter norepinephrine throughout the brain via widespread efferent projections, and plays a pivotal role in modulating cognitive activities in the cortex. Profound noradrenergic degeneration in Alzheimer's disease (AD) patients has been observed for decades, with recent research suggesting that the locus coeruleus (where noradrenergic neurons are mainly located) is a predominant site where AD-related pathology begins. Mounting evidence indicates that the loss of noradrenergic innervation greatly exacerbates AD pathogenesis and progression, although the precise roles of noradrenergic components in AD pathogenesis remain unclear. The aim of this review is to summarize current findings on noradrenergic dysfunction in AD, as well as to point out deficiencies in our knowledge where more research is needed. [ABSTRACT FROM AUTHOR]
