Abstract
Background and Objectives: Diabetes is considered as one of the most common endocrine disorders worldwide. The aim of this study was to investigate the factors associated with diabetic complications.
Methods: A case-control study was performed on the data of 70089 diabetic patients (4622 cases and 53613 controls) extracted from the SINA Electronic Health Record (SinaEHR®) in a population covered by Mashhad University of Medical Sciences in 2018. The effect of independent variables on the likelihood of diabetic complications was investigated using single-variable and multivariate logistic regression models with the control of the potential confounding effects.
Results: Using the multivariate logistic regression, the odds of developing diabetic complications were 0.35 (0.31-0.38) for living in the city, 0.73(0.67-0.79) for living in the suburbs and 0.31(0.28-0.33) for living in rural areas relative to the metropolises, 0.84 (0.78-0.91) for illiterate subjects, 0.70 (0.66-0.75) for physical activity, 1.51(1.34-1.71) for stage 1 hypertension and 1.87 (1.43-2.44) for stage 2 hypertension relative to normal blood pressure, 0.79(0.74-0.85) for uncontrolled low density lipoprotein and 1.42(1.33-1.51) for uncontrolled hemoglobin A1C.
Conclusion: Various risk factors were identified to increase the odds ratio of diabetic complications. The most important risk factors were uncontrolled glycosylated hemoglobin and stage 1 and 2 hypertension. Control of these factors can reduce the chance of diabetic complications in diabetic patients.

Abstract
Background and Objectives: In the late 2019, the SARS-CoV-2 virus was identified as the cause of an outbreak of acute respiratory illness known as the COVID-19, which began to spread in the world very quickly. Preventive measures have been a significant issue in preventing the spread of COVID-19. This rapid review study was conducted to summarize selected countries' preventive policies and strategies in the East and Southeast Asia, including China, South Korea, Japan, Vietnam, and Singapore, during the COVID-19 epidemic.
Methods: In this rapid review study, the Scopus, PubMed, Embase, and Web of Science databases were searched. The keywords applied in the search strategy were primary health care, public health, prevent* and plan, policy, program, initiative, intervention, measure, and COVID-19 in addition to the name of each country. Furthermore, we searched the World Health Organization (WHO) and the United Nations Development Program (UNDP) websites to retrieve more key sources as grey literature. The relevant data were extracted from the final studies and categorized.
Results: After screening, 33 studies met the inclusion criteria. Dominant measures implemented in these countries were categorized into different categories including communication and information, physical distancing, quarantine, monitoring, and testing axes.
Conclusion: Education and information, extensive testing and screening, contact tracing, isolation of infected and suspected cases, and observance of physical distancing has been very effective in reducing Covid-19 transmission and its mortality.

Abstract
Background and Objectives: Viral hepatitis is one of the most prevalent diseases and an important underlying cause of death and disability in the world. This case-control study was conducted to investigate the outbreak of hepatitis A in Boroujerd in 2019.
Methods: This case-control study was conducted to investigate the epidemic of hepatitis A in Boroujerd in 2019. Fifty hepatitis A patients were recruited. For each patient diagnosed, two controls with no history of the disease were selected from a neighboring village. Data were collected using a demographic questionnaire as well as the results of experiments. To investigate the association between the disease and risk factors, odds ratio and 95% confidence interval were used.
Results: In this study, the odds ratios were significant for a number of risk factors including washing fruits and vegetables with a source other than tap water [OR = 3.2], washing dishes with a source other than tap water [OR = 3.7], non-sanitary toilets [OR = 8.3], using sources other than tap water when there is no tap water [OR = 4.4], being unaware of the disease and its transmission methods [OR = 4.8] and water well dug less than 15 m from the sewage well (OR = 4.1).
Conclusion: Increased public awareness and improved health status of the environment and rural sewage can preclude similar epidemics in the study area and other regions.

Abstract
Background and Objectives: COVID-19 is a new disease and little information is available on its risk factors. The aim of this study was to determine the mortality risk factors in patients with COVID-19 in the northeast of Iran.
Materials and Methods: A case-control study was conducted. Patients of both sexes with a confirmed diagnosis of Covid-19 infection who died during the study were studied as the case group and patients who were in good general health and ready for discharge were studied as the control group. Data analysis was performed with the STATA software version 14 using descriptive statistics and univariate and multiple logistic regression tests.
Results: Six hundred and eleven patients were studied (27% cases and 73% controls). Multiple logistic regression analysis showed that the odds of death were 2.8 times higher in patients over 80 years compared to patients aged 50-60 years. In addition, age under 40 years reduced the odds of mortality by 85% and living in rural areas increased odds of death by 2.2 times. Cough, general fatigue, pain, nausea and vomiting increased the odds of COVID19 survival.
Conclusion: The odds of mortality were higher in elder patients with COVID-19. In addition, living in rural areas increased the odds of mortality in patients. Cough and fatigue reduced mortality; however, it is needed to address other hidden factors for sound judgment.

Abstract
Background and Objectives: During the COVID-19 pandemic, vaccination was crucial in preventing the spread of SARS-CoV-2 and saving numerous lives. Countries implementing COVID-19 vaccination programs have reported significant reductions in cases, ICU admissions, and COVID-19-related deaths. This study aimed to evaluate the effectiveness of vaccines used in Hamadan province, explicitly focusing on their impact on hospitalization and death caused by COVID-19.
Methods: A test-negative case-control design (TND) was conducted involving patients aged 12 and above who were admitted to hospitals in Hamadan province, Iran, and had symptoms of acute respiratory diseases. Data were extracted from hospital and health system databases. Multiple logistic regression analysis was performed to estimate vaccine effectiveness for the first, second, and reminder doses in prevention of hospitalization, and severe outcomes (ICU admission or death).
Results: The study was conducted on 3,702 patients, and the maximum effectiveness of vaccines against hospitalization was 50% for patients who received a booster dose. The effectiveness of the first dose of vaccine on severe outcomes (admission to ICU or death) was estimated as 42%, but the effectiveness of the vaccines in the second and booster doses were not significant.
Conclusion: Despite the predominant use of inactivated virus vaccines and delayed initiation of vaccination in Iran, this study shows the effect of vaccination on reducing hospitalization and improving the outcomes of COVID-19. The use of more effective vaccines at a more appropriate time plays an important role in reducing the burden on health services and preventing further transmission in future epidemics.
