Abstract
Background & Objective: Clinically Chronic Allograft Dysfunction (CAD) is characterized by a progressive decline in Glomerular Filtration Rate (GFR) over time, the pattern of disease progression determined by the five-stage model. In this paper, we used Erlang and Hypo-exponential distributions as Phase- Type distributions to describe hazard of kidney failure at over time in RTR with CAD.
Methods: In a single-center retrospective study, 214 patients with RTR with CAD were investigated at the Emam Hospital of Urmia University of Medical Sciences from 1997 to 2005. Kidney function at each visit assessed with GFR and categorized based on NKF and KCOQI staging system.
Results: The estimated hazard rates of disease progression from stage 1 to 2 , 0.0378 from stage 2 to 3 ,0.04 from stage 3 to 4 , 0.0458 and from stage 4 to 5 0.0541 were respectively based on each expected month . This estimates yield a mean waiting time of disease progression from stage 1 to Kidney failure or dialysis 91.63 month. The 18th, 58th, 118th and 155th months of death-censored graft survival were 0.99, 0.75, 0.25 and 0.10 respectively.
Conclusions: The findings of this study are compatible with hyperfiltration theory in chronic kidney disease and give us more detailed information about the daynamic process of disease which would help to manage it effictevliy.

Abstract
Background and Objectives: Traffic accidents are a leading cause of disability and mortality worldwide. This study was conducted to determine the days of disability and severity of injuries caused by traffic accidents in patients admitted to Imam Khomeini Hospital, Urmia in 2016.
Methods: This cross-sectional study was performed on 1705 traffic accident victims admitted to Imam Khomeini Hospital, Urmia in 2016. Data were collected using a checklist containing demographic information, accident, severity of injury, and days of disability along with a telephone follow-up after 3 months upon return to work or school. The ISS (Injury Severity Score) was categorized from 1 to 6 according to the experts’ opinions.
Results: The results showed that 1231 subjects (72.1%) were male and the mean and SD age of the participants was 33.63 (30.00) years. Moreover, 77 (0.04%) of the subjects died and 593 (42.5%) resumed a normal life after two months. The mean time to resuming a normal life was 86.78 (24.104) days. Most of the subjects had mild limb injury, while the majority of the deaths had life-threatening injuries.
Conclusion: In this study, most of the victims were male, married, young, and concerned about financial compensation. The majority of the deceased had life-threatening injuries requiring vital measures to return to work quickly.

Abstract
Background and Objectives: Animal bites are one of the most important public health problems that cause rabies. This study aimed to investigate the preventive measures taken for animal bite cases that occurred in West Azerbaijan province during 2012 to 2019.
Methods: This cross-sectional study involved the review data from all animal bite cases referred to rabies care centers in West Azerbaijan province. Information regarding prophylactic measures to prevent rabies, including post-bite procedures (washing, disinfection, dressing, stitches and receiving antibiotics), anti-rabies vaccine status (referral delay, vaccine dose received, vaccination history, anti-rabies serum, tetanus vaccination history) was analyzed using descriptive statistics. The relationship between delay in referral and the measures taken was investigated using the Chi-square test.
Results: Over the studied years, there were 47131 cases of animal bites. Among these, 63.9% were referred without delay, while 36.1% experienced a delay in referral. Notably, 99.6% of wounds were washed with soap and water, 94.5% were disinfected, and 31.3% received antibiotics. The proportion of individuals receiving antibiotics was significantly higher among those with delayed referrals. Regarding rabies vaccination, 77.3% had received all three initial doses, 15.4% had completed five doses, and 1.1% had not received any vaccine.
Conclusion: While prophylaxis measures for animal bite cases are commendable, there is a critical need for timely administration of rabies vaccine in rabies care centers. Implementing educational programs for general population to encourage prompt treatment-seeking in the event of animal bites is essential.
