Abstract
BACKGROUND AND OBJECTIVE The COVID-19 pandemic placed considerable pressure on the health care systems and caused many disruptions to the care hospital system around the globe. This study aimed to analyze the performance of hospitals affiliated with the University of Medical Sciences and Health Services of South Khorasan Province before and during COVID-19. METHOD This cross-sectional study tracked the financial performance (FP) and service performance (SP) of 12 hospitals affiliated with South Khorasan University of Medical Sciences and Health Services using the Farabar system and Hospital Information System (HIS). Our study covered two time periods: from February 2018 to February 2020 (pre-COVID-19) and from February 2020 to February 2021 (during COVID-19). SP analysis of hospitals was performed by examining the trend of monthly changes before and during the COVID-19 pandemic and analyzed using SPSS software version 22 and Paired Sample T-Test. FP of hospitals was analyzed through relevant ratios and analyzed using Microsoft Office Excel. RESULTS Most SP indicators decreased considerably in all hospitals during COVID-19. FP ratios (e.g., activity and leverage ratios) increased during either or both pre-COVID or COVID periods. Compared to before COVID-19, the operating margin ratio and operating expenses coverage from operating income increased from -0.50 and 66.55 to -1.42 and 41.32, respectively, during COVID-19. Moreover, the net profit margin ratio and Return On Assets (ROA) ratio were increased during COVID-19. CONCLUSION COVID-19 has decreased the FP and SP of hospitals due to limitations in providing services to patients since the beginning of COVID-19. Measures such as providing various financing resources and improving the financial resilience of hospitals are essential. Funds should be disbursed to offset hospitals' losses due to reduced elective and outpatient revenue. Policymakers should come up with holistic policies to tackle the adverse impact of such crises in the future, support hospitals financially, and consider allocating additional funding to them during emergencies.

Abstract
Background and Aims Type 2 diabetes mellitus (T2DM) is a prevalent public health problem worldwide, and the economic burden of the disease poses one of the main challenges for health systems in low- and middle-income countries. This study aimed to estimate the economic burden of T2DM in Iran, in 2018. Methods This was a cost-of-illness study. Three hundred and seventy-five patients with T2DM who were referred to Imam Reza and Sina's educational and therapeutic centers and Asad Abadi clinic in Tabriz, Iran, in 2018 were included. A researcher-constructed checklist was used for data collection. Data were analyzed using EXCEL and SPSS software version 22. Results Total economic burden of diabetes was estimated at 152,443,862,480.3 (purchasing power parity [PPP], Current International $) (approximately 7.69% of GDP, PPP, Current International $). The mean total direct and indirect costs were 11,278.68 (PPP) (62.35% of mean total cost) and 6808.88 (PPP, Current International $) (37.64% of the total cost), respectively. The mean total direct medical cost and the direct nonmedical cost were 10,819.43 (PPP, Current International $) (59.81% of mean total cost) and 459.24 (PPP, Current International $) (2.53% of mean total cost) per patient, respectively. Besides, the mean direct medical cost was 6.18 times the total per capita expenditure on health, and the total direct medical cost was 8.9% times the total expenditure on health. Conclusion Diabetes imposes a substantial economic burden on patients, health systems, and the whole economy. Besides, since the cost of the disease in patients treated with insulin and those with diabetes complications is significantly higher, the reinforcement of self-care measures and focusing on modifying lifestyle (dietary modification and physical activity) in patients with T2DM can significantly reduce the costs of the disease.

Abstract
Background and Aims Diabetes can lead to multiple complications that can reduce the quality of life, impose additional costs on the healthcare systems and ultimately lead to premature death. Proper self-care in diabetic patients can impede or delay the onset of diabetes complications. This study aimed to investigate diabetes complications and their association with diet knowledge, skills, and self-care barriers. Methods This was a cross-sectional study. A total of 1139 patients with Type 2 Diabetes Mellitus (T2DM) referring to health centers in Tabriz, Iran, were included from January to July 2019. Data were collected using two questionnaires: (1) a sociodemographic questionnaire and (2) a Personal Diabetes Questionnaire (PDQ). Data were analyzed using SPSS software version 22. χ 2 test was used to examine the association between the socioeconomic and disease-related variables and the prevalence of diabetes complications. T-test was used to examine the association between diet knowledge and skills, self-care barriers, and the incidence of diabetes complications. Results In this study, 76.1% of patients had at least one complication, and 30.2% had a history of hospitalization due to diabetes complications during the past year. Approximately 49% and 43% were diagnosed with high blood pressure and hyperlipidemia, respectively. Cardiovascular disease was the most common diabetes complication (15.9%) and the cause of hospitalization (11.01%) in patients with diabetes. Barriers to diet adherence, blood glucose monitoring, and exercise were significantly associated with self-reported diabetes complications (p < 0.001). Our results showed no significant association between the number of complications and diet knowledge and skills (p = 0.44). Conclusion This study indicated that the prevalence of diabetes complications was higher among patients with more barriers to self-care. In light of these findings, taking appropriate measures to reduce barriers to self-care can prevent or delay the onset of diabetes complications.

Abstract
Background and Aims Elderly people are potentially vulnerable with a higher need for health services, and utilization of Essential Public Health Services (EPHS) among this group is of high importance. This study aimed to examine the utilization of health services among the elderly in Iran during the coronavirus disease 2019 outbreak. Methods This was a cross-sectional study conducted in 21 public health centers in Sirjan, Southern Iran, from May to December 2020. A total of 420 elderly patients were selected through a systematic random sampling method. Data were collected using a questionnaire and were analyzed using SPSS v22.0. The binary logistic regression was used to examine the effect of demographic, socioeconomic and morbidity status on inpatient and outpatient healthcare utilization. Results Our results showed that 56% of the elderly had a history of hospitalization during the last year. Although 60% of the elderly reported they had a perceived need for outpatient services, only 49% of them reported that they utilized outpatient services. 51% and 35.5% of the elderly reported that their inpatient and outpatient costs were covered by health insurance, respectively. Others reported their health spending was financed through out-of-pocket payments. Male gender aged 80 and above, urban residents, higher socioeconomic and supplemental insurance coverage were associated with an increase in health services utilization. The elderly with Cancer, mental disorders, kidney disease, and cardiovascular diseases (CVDs) were more likely to be hospitalized. Conclusion There were demographic and socioeconomic inequalities in health services utilization among the elderly. Therefore, appropriate interventions and strategies are needed to reduce these inequalities in health services utilization among the elderly. In addition, given that the hospitalization rate was significantly higher among the elderly with chronic diseases than those without, it is crucial and necessary to take interventions to reduce the burden of chronic diseases in the future.

Abstract
OBJECTIVES This study aimed to estimate the cost of COVID-19 patients and some affecting factors in Iran. METHODS This was a prevalence-based cost-of-illness study based on a bottom-up costing approach which was conducted from March 2020 to July 2020. Data were extracted from the hospital's Hospital Information System (HIS) and Cost-of-illness (COI) assessment checklist. Indirect costs were assessed based on the Human Capital Approach. Data were analyzed using SPSS software version 22 and Microsoft EXCEL 2016. RESULTS A total of 745 Covid-19 patients were included in the analysis. The mean total cost was estimated at 8813.15 (PPP, Current International $), accounting for 60% of GDP per capita. The mean direct and indirect cost was 3362.49 (PPP, Current International $) (38% of the total cost and 23% of the GDP per capita), and 5450.66 (PPP, Current International $) (62% of the total cost and 37% of the GDP per capita), respectively. The mean hospitalization cost was higher among patients who died and those who were covered by supplemental insurance. Also, the costs of disease experienced a dramatic rise with increasing age. For different scenarios in terms of outbreak rate, hospitalization rate and mortality rate, the total estimated cost of illness for Covid-19 ranged from 6263 million (PPP, Current International $) to 63,474 million (PPP, Current International $). CONCLUSIONS Covid-19 imposes a substantial financial burden on people, health care systems, insurance organizations and the country's economy as a whole. Since the economic burden of this disease increases dramatically by increasing disease outbreak, more attention should be paid to the development and implementation of appropriate preventive programs.

Abstract
BACKGROUND AND OBJECTIVE Diabetes mellitus is a complex chronic disease requiring appropriate continuous medical care and delayed, or forgone care may exacerbate the severity of the disease. This study aimed to investigate the factors affecting forgone care in patients with type2 diabetes. MATERIALS AND METHODS This was a cross-sectional study involving 1139 patients with type 2 diabetes aged> 18 years in 2019 in Tabriz, Iran. The researcher-made questionnaire was used for data collection. Data were analyzed using IBM SPSS software version 22 and IBM AMOS 22. Exploratory Factor Analysis (EFA) was performed for dimension reduction of the questionnaire, and Confirmatory Factor Analysis (CFA) used to verify the result of EFA. We applied the binary logistic regression model to assess the factors affecting forgone care. RESULTS Of the 1139 patients, 510 patients (45%) reported forgone care during the last year. The percentage of forgoing care was higher in patients without supplementary insurance coverage (P = 0.01), those with complications (P = 0.01) and those with a history of hospitalization (P = 0.006). The majority of patients (41.5%) reported that the most important reason for forgoing care is financial barriers resulting from disease treatment costs. Of the main four factors affecting, quality of care had the highest impact on forgone care at 61.28 (of 100), followed by accessibility (37.01 of 100), awareness and attitude towards disease (18.52 of 100) and social support (17.22 of 100). CONCLUSION The results showed that, despite the implementation of the Islamic Republic of Iran on a fast-track to beating non-communicable diseases (IraPEN), a considerable number of patients with type2 diabetes had a history of forgoing care, and the most important reasons for forgoing care were related to the financial pressure and dissatisfaction with the quality of care. Therefore, not only more financial support programs should be carried out, but the quality of care should be improved.

Abstract
BACKGROUNDS Breast cancer is the most prevalent cancer among women. Breast cancer imposes a considerable economic burden on the health system. This study aimed to compare the cost of breast cancer among patients who referred to private and public hospitals in Iran (2017). METHODS This was a prevalence-based cost of illness study. A total of 179 patients were selected from private and public hospitals using the census method. The researcher-constructed checklist was used for data collection. Data were analyzed using SPSS software version 22. RESULTS The estimated total mean (SD) direct cost of patients who referred to the private hospital and the public hospital was $10,050 (19,480) and $3960 (6780), respectively. Further, the total mean indirect cost of patients who referred to the private hospital was lower than those referring to the public hospital at $1870 (15 % of total costs) and $22,350 (85 % of total costs), respectively. These differences were statistically significant (P < 0.05). CONCLUSIONS Breast cancer imposes a substantial cost on patients, health insurance organizations and the whole society in Iran. Therefore, the adoption of effective measures for the prevention and early diagnosis of breast cancer is urgently needed.

Abstract
BACKGROUND AND OBJECTIVE Despite the expansion of salinity in arid and semiarid regions, the measurement of exchangeable cations concentrations such as exchangeable sodium ratio in saline soils remains difficult. Exchangeable sodium ratio (ESR) often measured by using the time-consuming laboratory tests. The correlation between ESR and sodium adsorption ratio (SAR) has documented in many studies. However, no studies have undertaken to model soil ESR in the Sarakhs Plain, Northeast Iran. The aim of this study was to evaluate a linear regression model between soluble and exchangeable cations in this area. MATERIALS AND METHODS In this study, 124 soil samples randomly taken from surface and subsurface the experimental site. The soil samples collected using a soil auger at 0-30 cm and 30-60 cm depth. Then the linear regression model was used for predicting soil (ESR) on saline soil. The soil ESR values measured in soil samples compared to the soil ESR values predicted using the soil ESR-SARmodel. RESULTS The statistical results indicate that in surface soil (0-30 cm) and subsurface soil (30-60 cm), to predict soil ESR from soil SAR, the linear regression model ESR = 0.0182SAR-0.027 with (R2 = 0.92, p<0.001) and ESR = 0.0157SAR-0.020 with (R2 = 0.83, p<0.001) can be recommended, respectively. CONCLUSION In conclusion, the soil ESR-SAR model recommended for the prediction of soil ESR to its significant importance reducing in time and field checking.

Abstract
BACKGROUND Despite the popularity of ice cream, its high content of sugar and fat is worrisome. Substituting sugar with natural and useful resources is one possible solution. Dates (Phoenix dactylifera) are rich in carbohydrates and are a good source of energy; they also have a large amount of phenolic compounds and anthocyanin. AIMS The aim of this study is to evaluate the effect of ice cream sugar replacement with date products. METHODS Accordingly, four ice cream samples with different sweeteners including 1) sucrose (as a control), 2) date pulp + sucrose, 3) date liquid sugar, and 4) sucrose + date liquid sugar, were produced. Total phenolics, anthocyanins, and antioxidant activities of dates and their effects on physicochemical and sensory properties of ice cream were investigated. RESULTS A large amount of phenolic compounds and anthocyanin was found in the ice cream contained date pulp and liquid sugar, which enhanced the reducing power and antioxidant effect of it. The overrun and density of an ice cream did not change with sugar replacement. Total substitution of sucrose by date liquid sugar, increased the titratable acidity, viscosity, and antioxidant properties of ice cream, but it was found to have some negative effects on the organoleptically score of color. However, the partial replacement of granular sugar with date pulp/liquid sugar, improved the antioxidant value of this dairy dessert without any change in its color. CONCLUSION It seems that the addition of date pulp to an ice cream, not only maintain the quality and sensory properties of an ice cream, but also provides an antioxidant property.

Abstract
Background: The genes encoding IL9, IL9R, IL17A, and IL17F have recently been implicated in the genetic basis of rhinitis and allergy. Aim: The purpose of this study was to assess the association of the single nucleotide polymorphisms (SNPs) of IL9, IL9R, IL17A, and IL17F and potential interaction of these genes with the determination of IgE levels in women with allergic rhinitis (AR) in Shahrekord, Iran. Subjects and Methods: In a case–control study, SNPs from the IL9, IL9R, IL17A, and IL17F were genotyped in 394 random samples including 195 AR patients and 199 normal controls. Enzyme-linked immunosorbent assay was performed for the determination of serum total IgE levels. The Student's t-test was used to compare the differences. The Chi-square test was performed to compare proportions of cases with different clinical features among cases with different genotypes. The genotype and allele frequencies were obtained by direct counting. Hardy–Weinberg equilibrium was tested between cases and controls separately. The relative risk associated with rare alleles was estimated as an odds ratio with 95% confidence interval. P ≤ 0.05 was considered statistically significant. Results: The rs731476 SNP in the IL9R was significantly associated with the AR phenotype in women. No association was found between any of the other SNPs in IL9, IL17A, and IL17F genes and AR. In the gene–gene interaction analysis, we found that IL9R/IL9 genotype rs731476 T-/rs2069885 G conferred a higher risk for AR phenotype development. We also did not find a significant association in terms of IgE levels between cases and controls. Conclusion: Our result suggests that the rs731476 SNP located in the IL9R is associated with an increased susceptibility to AR in females. In a subsequent gene–gene interaction analysis, the rs731476 T-/rs2069885 G-genotype combination (IL9R/IL9) has significantly been associated with the development of the AR phenotype.

Abstract
In the transplant recipient patients receive immunosuppressive therapy, the possibility of reactivation of the old infection or acquisition of infection from a donor's tissue increases. In this study, IgM and IgG anti-Toxoplasma immunoglobulins seroconversion in renal transplant recipients (RTRs) have been evaluated before and after transplantation. This is a prospective cohort study on a total of 102 RTRs. Two serum samples were obtained from each patient. The first was taken before administration of any immunosuppressive drugs such as corticosteroids and the second was taken 3 months after transplantation. The IgM and IgG anti-Toxoplasma antibodies were assayed by enzyme-linked flourescence assay (ELFA) and enzyme-linked immunosorbent assay (ELISA) techniques. IgM/immunosorbent agglutination assay (ISAGA) method has also been used. All RTRs were tested for toxoplasmosis before and after transplantation. ELFA identified 65 (63·7%) pre-transplantation samples as IgG+ and did not detect any positive IgM samples. However, IgM was detected in three (2·9%) post-transplantation samples by this method. Forty-nine (48%) pre-transplantation samples were reported IgG+ by ELISA and no IgM positive sample was identified by this method. ELISA has detected two (1·9%) IgM-positive reactions in post-transplantation samples. By IgM/ISAGA method, we have detected no IgM positive reactions in pre-transplantation samples, whereas 3 months later (second sampling) IgM antibody was detected in 3 (2·9%) cases. Secondary toxoplasmosis infection was observed in 30 cases per 1000 RTRs, which indicates that screening for toxoplasmosis infection should be performed in developed countries for these patients. On the other hand, as the risk of re-active toxoplasmosis infection exists in developing nations, they should consider the necessary preventive measures to control this condition.

Abstract
Regional differences in the content of intramyocellular lipids (IMCL), extramyocellular lipids, and total creatine (TCr) were quantified in soleus (S), tibialis posterior (TP), and tibialis anterior (TA) muscles in humans using in vivo 1H proton spectroscopic imaging at 4 T. Improved spatial resolution (0.25-ml nominal voxel resolution) made it feasible to measure IMCL in S, TP, and TA simultaneously in vivo. The most significant regional difference was found in the content of IMCL compared with extramyocellular lipids or TCr. The concentrations of TCr were found to be 29-32 mmol/kg, with little regional variation. IMCL content was measured to be 4.8 +/- 1.6 mmol/kg tissue wt in S, 2.8 +/- 1.3 mmol/kg tissue wt in TP, and 1.6 +/- 0.9 mmol/kg tissue wt in TA in the order of S > TP > TA (P < 0.05). It is likely that these IMCL values are consistent with the known fiber types of these muscles, with S having the greatest fraction of type I (slow-twitch, oxidative) fibers and TA having a large fraction of type IIb (fast-twitch, glycolytic) fibers.
