    This study aims to assess the relationship between structural dimensions of organization including centralization, complexity and formalization on one side and strategy effectiveness on the other side. Structural dimensions are determined based on Robbins theory, and each of them is considered as independent variables of research. Strategy effectiveness, which includes achieving strategic goals or successful implementation of strategies are the independent variable of the research, based on Noble’s strategy implementation model. One primary thesis and three secondary these are defined. This is a descriptive research of two variable correlation. The target population includes 600 senior managers of Payam-e-noor university around the country, including staff administrative managers, province and unit headmasters, of Iran at the time of data collection. Simple random sampling is used, with sample size of 120. Library resources are used for theoretical foundation data collection and note-taking. Questionnaires are used to collect data and evaluate research theses. Inferential Statistics and Pearson correlation coefficient are used to analyze the research theses. The first two theses are confirmed, at 95% and 99% respectively, but the third thesis is rejected based on the collected data. Therefore, based on this study, complexity and formalization have respectively inverse and direct effect on strategy effectiveness, but centralization does not affect strategy effectiveness in Payam-e-noor University

    Background: Universal Design (UD) means designing the products and environments everyone can use as far as possible without requiring specialized compatibility or design. The present study aimed to design and develop a comprehensive and valid checklist to evaluate the design of banks based on UD principles and implement it in Iranian banks.Methods: Based on the seven UD principles and using a mixed methods sequential exploratory design, an initial checklist with 61 items was developed. Then, its psychometric properties were evaluated based on face and content validity and inter-rater agreement. The final checklist was prepared based on the results of this stage and used in the next stage to evaluate the design of 17 banks.Results: The final checklist consisted of 10 areas (as per the seven UD principles). The Content Validity Ratio (CVR) and Content Validity Index (CVI) were calculated as 0.91 and 0.93, respectively. Based on areas of the checklist, all the evaluated banks showed many problems, the most significant of which were related to the areas of equal use by different groups, flexibility in use, and the size and space of access and use.Conclusion: The present study’s findings led to the design of a comprehensive and standard checklist to evaluate the design of banks in terms of UD principles. The results indicated that the UD principles were not observed in most studied banks, and they need to implement targeted design interventions

    Objective: The annual incidence of squamous cell carcinoma (SCC) has been increasing worldwide. The causative role of human papillomavirus (HPV) in SCC development of cutaneous has been controversial in the literature. In this study, we aimed to assess the presence of the histopathological features of HPV in SCC samples. Materials and Methods: This retrospective study was conducted at a tertiary referral skin center in 2020. Specimens of patients with a definite SCC diagnosis were evaluated for histopathological features of HPV, including koilocytosis, hyperkeratosis, acanthosis, hypergranulosis, parakeratosis, solar elastosis, papillomatosis, as well as the grade of the tumor. All the samples were re-evaluated by two dermatopathologists independently. Results: a total of 331 (male:female ratio= 3.9:1) cases of SCC were analyzed. The mean age was 68.1, with a 15.1 standard deviation. Most lesions were located on the face (40.5%), followed by the scalp (22.7%) and extremities (20.8%). Koilocytes were detected in 50 (15.1%) of lesions. The koilocytosis proportion was significantly higher in lesions on nails (38.1%, P-value= 0.007), oral cavity (36.8%, P-value= 0.014), and genitalia lesions (60.0%, P-value= 0.026). Although SCCs in-situ were found in 6.6% of our specimens, the highest koilocytosis proportion (64.7%) was detected in in-situ tumors, which was significantly more than other grades (P-value< 0.001). Conclusions: The histopathological features of HPV and in specific koilocytes can be frequently seen in SCC pathology. This association is more prominent in nail, oral, and genital lesions and is significantly higher in well-differentiated SCC

    Inflammatory bowel disease (IBD) is a chronic condition of the intestine with unknown etiology involving multiple immune, genetic and environmental factors. We were interested to examine the effect of total extract from Zataria multiflora Boiss, a folk medicinal plant on prevention and treatment of experimental IBD. Z. multiflora was administered (400, 600, 900 p.p.m.) through drinking water to IBD mice induced by intrarectal administration of acetic acid. Prednisolone was used as the standard drug for comparison. Biochemical, macroscopic and microscopic examinations of colon were performed. Biochemical evaluation of inflamed colon was done using assay of myeloperoxidase (MPO) activity and thiobarbituric acid reactive substances (TBARS) concentration as indicators of free radical activity and cell lipid peroxidation. The activity of MPO and lipid peroxidation products (TBARS) increased in acetic acid-treated groups while recovered by pretreatment of animals with Z. multiflora (400–900 p.p.m.) and prednisolone. Z. multiflora (600 and 900 p.p.m.) and prednisolone-treated groups showed significantly lower score values of macroscopic and microscopic characters when compared with the acetic acid-treated group. The beneficial effect of Z. multiflora (900 p.p.m.) was comparable with that of prednisolone. The antioxidant, antimicrobial and anti-inflammatory potentials of Z. multiflora might be the mechanisms by which this herbal extract protects animals against experimentally induced IBD. Proper clinical investigation should be carried out to confirm the activity in human

    Background Child mortality as one of the key Millennium Development Goals (MDG 4—to reduce child mortality by two-thirds from 1990 to 2015), is included in the Sustainable Development Goals (SDG 3, target 2—to reduce child mortality to fewer than 25 deaths per 1000 livebirths for all countries by 2030), and is a key indicator of the health system in every country. In this study, we aimed to estimate the level and trend of child mortality from 1990 to 2015 in Iran, to assess the progress of the country and its provinces toward these goals. Methods We used three different data sources: three censuses, a Demographic and Health Survey (DHS), and 5-year data from the death registration system. We used the summary birth history data from four data sources (the three censuses and DHS) and used maternal age cohort and maternal age period methods to estimate the trends in child mortality rates, combining the estimates of these two indirect methods using Loess regression. We also used the complete birth history method to estimate child mortality rate directly from DHS data. Finally, to synthesise different trends into a single trend and calculate uncertainty intervals (UI), we used Gaussian process regression. Findings Under-5 mortality rates (deaths per 1000 livebirths) at the national level in Iran in 1990, 2000, 2010, and 2015 were 63·6 (95% UI 63·1–64·0), 38·8 (38·5–39·2), 24·9 (24·3–25·4), and 19·4 (18·6–20·2), respectively. Between 1990 and 2015, the median annual reduction and total overall reduction in these rates were 4·9% and 70%, respectively. At the provincial level, the difference between the highest and lowest child mortality rates in 1990, 2000, and 2015 were 65·6, 40·4, and 38·1 per 1000 livebirths, respectively. Based on the MDG 4 goal, five provinces had not decreased child mortality by two-thirds by 2015. Furthermore, six provinces had not reached SDG 3 (target 2). Interpretation Iran and most of its provinces achieved MDG 4 and SDG 3 (target 2) goals by 2015. However, at the subnational level in some provinces, there is substantial inequity. Local policy makers should use effective strategies to accelerate the reduction of child mortality for these provinces by 2030. Possible recommendations for such strategies include enhancing the level of education and health literacy among women, tackling sex discrimination, and improving incomes for families

    An updated exploration of the burden of thyroid cancer across a country is always required for making correct decisions. The objective of this study is to present the thyroid cancer burden and attributed burden to the high Body Mass Index (BMI) in Iran at national and sub-national levels from 1990 to 2019. The data was obtained from the GBD 2019 study estimates. To explain the pattern of changes in incidence from 1990 to 2019, decomposition analysis was conducted. Besides, the attribution of high BMI in the thyroid cancer DALYs and deaths were obtained. The age-standardized incidence rate of thyroid cancer was 1.57 (95% UI: 1.33–1.86) in 1990 and increased 131% (53–191) until 2019. The age-standardized prevalence rate of thyroid cancer was 30.19 (18.75–34.55) in 2019 which increased 164% (77–246) from 11.44 (9.38–13.85) in 1990. In 2019, the death rate, and Disability-adjusted life years of thyroid cancer was 0.49 (0.36–0.53), and 13.16 (8.93–14.62), respectively. These numbers also increased since 1990. The DALYs and deaths attributable to high BMI was 1.91 (0.95–3.11) and 0.07 (0.04–0.11), respectively. The thyroid cancer burden and high BMI attributed burden has increased from 1990 to 2019 in Iran. This study and similar studies’ results can be used for accurate resource allocation for efficient management and all potential risks’ modification for thyroid cancer with a cost-conscious view

    Global burden of chronic respiratory diseases and risk factors, 1990–2019: an update from the Global Burden of Disease Study 2019

    Background: Updated data on chronic respiratory diseases (CRDs) are vital in their prevention, control, and treatment in the path to achieving the third UN Sustainable Development Goals (SDGs), a one-third reduction in premature mortality from non-communicable diseases by 2030. We provided global, regional, and national estimates of the burden of CRDs and their attributable risks from 1990 to 2019. Methods: Using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we estimated mortality, years lived with disability, years of life lost, disability-adjusted life years (DALYs), prevalence, and incidence of CRDs, i.e. chronic obstructive pulmonary disease (COPD), asthma, pneumoconiosis, interstitial lung disease and pulmonary sarcoidosis, and other CRDs, from 1990 to 2019 by sex, age, region, and Socio-demographic Index (SDI) in 204 countries and territories. Deaths and DALYs from CRDs attributable to each risk factor were estimated according to relative risks, risk exposure, and the theoretical minimum risk exposure level input. Findings: In 2019, CRDs were the third leading cause of death responsible for 4.0 million deaths (95% uncertainty interval 3.6–4.3) with a prevalence of 454.6 million cases (417.4–499.1) globally. While the total deaths and prevalence of CRDs have increased by 28.5% and 39.8%, the age-standardised rates have dropped by 41.7% and 16.9% from 1990 to 2019, respectively. COPD, with 212.3 million (200.4–225.1) prevalent cases, was the primary cause of deaths from CRDs, accounting for 3.3 million (2.9–3.6) deaths. With 262.4 million (224.1–309.5) prevalent cases, asthma had the highest prevalence among CRDs. The age-standardised rates of all burden measures of COPD, asthma, and pneumoconiosis have reduced globally from 1990 to 2019. Nevertheless, the age-standardised rates of incidence and prevalence of interstitial lung disease and pulmonary sarcoidosis have increased throughout this period. Low- and low-middle SDI countries had the highest age-standardised death and DALYs rates while the high SDI quintile had the highest prevalence rate of CRDs. The highest deaths and DALYs from CRDs were attributed to smoking globally, followed by air pollution and occupational risks. Non-optimal temperature and high body-mass index were additional risk factors for COPD and asthma, respectively. Interpretation: Albeit the age-standardised prevalence, death, and DALYs rates of CRDs have decreased, they still cause a substantial burden and deaths worldwide. The high death and DALYs rates in low and low-middle SDI countries highlights the urgent need for improved preventive, diagnostic, and therapeutic measures. Global strategies for tobacco control, enhancing air quality, reducing occupational hazards, and fostering clean cooking fuels are crucial steps in reducing the burden of CRDs, especially in low- and lower-middle income countries

    The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019

    Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

    BACKGROUND: This study was carried out aiming to investigate the identity crisis and emotional intelligence in prediction of addiction susceptibility among students. METHODS: This study was a correlational-descriptive design with the population consisting of all high school students of Tehran City, Iran, in 2017-2018. 358 high school students were selected by cluster sampling method. Instruments for gathering data were identity crisis questionnaire (Ahmadi), emotional intelligence questionnaire (Bradbury-Graves), and tendency to substance use scale. Then, the data were analyzed using SPSS software and statistical tests such as Pearson correlation coefficient and stepwise regression analysis. RESULTS: Based on study findings, there was a statistically significant relationship between identity crisis and emotional intelligence with addiction susceptibility among students. In addition, the results of stepwise regression analysis indicated that social awareness, identity crisis, and relation management significantly predicted 26% of changes in addiction susceptibility. CONCLUSION: By designing psychological interventions based on these variables, one can diminish the probability of substance use in at-risk groups. Theoretical and practical implications of the results presented have been discussed
