Abstract
Background and Objectives: Iran is classically located in the Palearctic zoogeographic zone, but southern pasts of Iran are drastically different from other parts in terms of fauna and flora. Nowadays, considering the technological advances and the ability to locate the zone border using aerial photos, and the need for comparing the prevalence of the diseases in different locations, it is necessary to identify the border of tropical-like zones as detailed as possible.
Methods: The shapefile of the political classification of Iran was used as the base map and metrological and terrestrial data were obtained from Iran Climatologic Research Center and literature review. Data were arranged in the Geospatial Information System and after geostatistical analysis, a raster map was generated and a probability map for all tropical conditions was calculated and generated as a raster map. Tropical areas were proposed in two layers.
Results: According to our study, between 113 to 125 districts from 8 provinces were located in tropical-like zones. Three of these districts had typical criteria of the Indo-Malayan zone and others resembled the Afrotropical zone. The table of the districts located in the tropical-like zones and the shapefile of these areas are available on the website of Iran Epidemiology Society.
Conclusion: Although Iran in located in the Palearctic zoogeographic area, there are some southern areas which resemble tropical regions and accurate definition of borders is a basic essential need for geo-referenced epidemiology and determining the disease pattern. This study provided a preliminary map for this field of study.

Abstract
Background and Objectives: The cancer of the pancreatic head and Ampulla of Vater is a malignant disease usually seen in advanced stages with symptoms caused by stomach and biliary obstruction. Curative treatment is possible in the early stage. Unfortunately, most symptomatic patients are in the advanced stage and have an unrespectable tumor; therefore, they should undergo palliative surgery. This study was performed to determine the complications and survival rate of patients who underwent palliative surgery for advanced stages of cancer in the Ampulla Vater and pancreatic head.
Methods: In this study, 49 patients with advanced stages of cancer in the Ampulla of Vater and pancreatic head who had undergone palliative surgery from 2003 to 2014 at Baqiyatallah Hospital were studied and the complications and survival rate were determined.
Results: Eleven patients (22.44%) underwent biliary bypass, 6 (12.24%) underwent gastric bypass, and 32 (65.32) underwent both procedures. Twelve (24.49%) patients developed complications. Anastomotic leak and peritonitis were the most common complications seen in 6 (12.2%). Seven patients (14.28%) died in the hospital. The mean survival was 5.47 ± 8.38 months. Upon follow up, survival was significantly longer in older patients (P=0.01).
Conclusion: In one-fourth of the patients with advanced stages of cancer, palliative surgery of the pancreatic head and Ampulla of Vater caused complications, and the mean survival rate was less than six months. The results of this study recommend the use of less invasive procedures such as biliary stenting in the advanced stages of the disease.

Abstract
Background and Objectives: Neuropathy is a common complication of diabetes that can cause disability in diabetic patients. The aim of this study was to determine of effective factors in the Event Time of neuropathy in type 2 diabetic patients using the Cox proportional hazards model.
Methods: This study included 371 patients with type II diabetes without neuropathy who were registered at Fereydunshahr Diabetes Clinic. Subjects were followed up for the development of neuropathy between 2006 until March 2016. The data were analyzed using the R software (ver. 3.2.3). The test was conducted at an error level of 5%.
Results: At the end of 10 years of study, the cumulative incidence and prevalence of neuropathy was 30.7% and 41.6%, respectively. The Kaplan-Meier method showed the mean time to detection of neuropathy was 76.6 ± 5 months after the first diagnosis of diabetes (83.8 ± 8 in men and 72.7 ± 6 in women). The semi-parametric Cox regression model revealed the one-year, two-year, five-year, and eight-year disease-free survival was 0.867, 0.819, 0.647, and 0.527, respectively. Also, four variables of duration of diabetes, sex, family history of diabetes, and HbA1c can be considered as strong determinants of the time of development of neuropathy in the semi-parametric model (COX) (P<0.05).
Conclusion: Optimal glycemic control and regular evaluation of legs in elderly patients, especially women with a positive family history, decrease the occurrence and progression of neuropathy and improve the quality of life in diabetic patients.

Abstract
Background and Objectives: This study was conducted to compare the personality type and alexithymia between opiates dependents, concurrent opiates and methamphetamine users and control groups presenting to drug abuse treatment centers in Kerman in 2020.
Methods: In this cross-sectional analytical study, three groups with a sample size of 130 participants were recruited through convenience sampling from six drug abuse treatment centers (two governmental and four private centers) in Kerman, 2020. The first group comprised opiates-only users. The second group included concurrent opiates and methamphetamine users. The third group included never-drug users. The data were collected using three questionnaires including a demographic questionnaire, the Friedman and Rosenman personality types questionnaire and Toronto Alexithymia Scale. Comparison of variables between the three groups was done using multivariable multinomial logistic regression.
Results: The research outcomes indicated a higher chance of type A personality in the opiates with methamphetamine dependents (adjusted odds ratio (AOR):1.97; 95% confidence interval (95% CI): 3.64, 1.06) compared to the control group. The chance of severe alexithymia was higher among opiates dependents (AOR: 1.86; 95% CI: 3.27, 1.06) and concurrent opiates and methamphetamine users (AOR: 2.7; 95% CI: 4.83, 1.51) compared to the control group. The concurrent opiates and methamphetamine users were more likely to be male (AOR: 3.1; 95% CI: 6.25, 1.53), single (AOR: 2.6; 95% CI: 4.72, 1.43) and unemployed (AOR: 4.01; 95% CI: 9.09, 1.77) compared to the control group. Compared to the control group, the opiates dependents (AOR: 4.14; 95% CI: 7.71, 2.22) and the opiates with methamphetamine dependents (AOR: 1.95; 95% CI: 3.69, 1.03) were more likely to have education levels lower than secondary school diploma.
Conclusion: Considering the relationship between the personality type and alexithymia with opiates and methamphetamine use, early screening, continuous care, and necessary trainings are required to prevent drug dependency in high-risk people, especially at younger ages.

Abstract
Background and Objectives: One of the important basis of health planning in any society is to identify the causes of death and the trend of each cause in that country over time. The purpose of this study is to investigate the trend of youth mortality and causes od death among young population of the Eastern Mediterranean region.
Methods: The present study conducted based on a secondary longitudinal analysis of death data to analyze the trend of youth mortality aged 15-24 and causes of death based on the ICD-10 in Eastern Mediterranean Region between 1990 and 2019. Study data were collected from the IHME Global Burden of Disease (GBD) website and analyzed using descriptive statistical and linear regression analysis. Death rate or cause is the dependent variable and time is the independent variable.
Results: The mortality rate of young people (15 to 24 years old) in all the countries of the Eastern Mediterranean region decreased from 1990 to 2019 except in Syria and Libya. Syria was the only country with a significant increase in the death rate. The most common cause of death was accidents; in general, the death rate related to this cause decreased during 30 years. Among the sub-groups of death causes among young people, the highest rate until 2010 was due to road accidents, which decreased over the study years. From 2010 onwards, death due to self-harm and interpersonal violence had the first rank.
Conclusion: Although a declining trend was observed during the last three decades among young people of Eastern Mediterranean region, deaths due to accidents are still considerable. It seems that the interventions to reduce death due to road accidents were successful; however, any policy and intervention to reduce death due to self-harm and interpersonal violence has a high priority.

Abstract
Background and Objectives: Masks play a crucial role in preventing and controlling viral epidemics transmitted predominantly through the air. This study aimed to develop and validate a tool to measure people’s attitudes and behaviors related to mask usage during highly contagious viral epidemics.
Methods: In this psychometric study, the initial questionnaire was developed and face validity and content validity were assessed by 17 experts and three lay experts. Reliability was evaluated through internal consistency using Cronbach’s alpha and test-retest reliability using the Intraclass Correlation Coefficient (ICC). Construct validity was measured using exploratory factor analysis (EFA) with the principal component extraction method and Varimax rotation.
Results: Based on a review of previous studies, an initial 27-item questionnaire was crafted. During the face validity stage, two items were excluded. Through calculating the Content Validity Ratio (CVR) and the Content Validity Index (CVI), three and one items respectively removed. The average scale level content validity index (S-CVI/Ave) was 0.95. Cronbach's alpha coefficient was found to be 0.76 for attitude and 0.66 for practice sections; the ICC was equal to 0.873. EFA revealed two factors explaining 63.98% of the total variance.
Conclusion: This questionnaire demonstrated sound reliability and validity in Persian, providing an effective means to assess attitude and behavior related to mask usage during highly contagious viral epidemics. It stands as a valuable tool for use in Iran and other countries.
