Prediction of spatial distribution for some land use allometric characteristics in land use planning models with geostatistic and Geographical Information System (GIS) (Case study: Boein and Miandasht, Isfahan Province, Iran)

Although traditional census can present unbiased information about different land uses, it is spatial independent and do not present particular  information about spatial distribution of studied characteristic. In this study, we used geostatistic and Geographical Information System (GIS) to estimate some different land uses allometric characteristics in Isfahan Province (Iran). Thus, samples information was surveyed considering their geographic position in the studied area. After optimizing variogram parameters,  empirical variogram was prepared to investigate spatial structure of different land uses allometric characteristics. Our results confirme that spatial  structure for the quantitative characteristics of different land uses has a moderate degree of spatial correlation, except for type variable that has no spatial structure. Nugget effect for variogram obtained from the quantitative characteristics of different land uses was equal to 35 to 64%. We used ordinary Kriging for preparing Kriging map and Kriging standard deviation of different land uses. Also, we used geostatistic and GIS to compare geostatistical and algebraic interpolation methods and nine different interpolation methods (Kriging, local polynomial methods, inverse distance weighted, radial basis functions, global polynomial, moving average  weighted, natural neighbor, nearest neighbor and triangulation with Linear Interpolation) were investigated. Spatial distribution of different land uses quantitative characteristics were validated with ordinary Kriging and algebraic methods. Our results confirm that ordinary Kriging has more accuracy than other methods for spatial prediction of different land uses quantitative characteristics.Key words: Geostatistic, interpolation method, land use allometric  characteristics, Kriging

COVID-19 pneumonia in a child with hepatic encephalopathy: A case study

Coronavirus disease 2019 (COVID-19) is caused by the seventh coronavirus, known as the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2). Children often have milder diseases than adults with very rare mortality. Gastrointestinal manifestations and a mild increase in liver enzymes have been reported in 8.8% to 53% of COVID-19 cases. However, liver failure is extremely rare and has not been reported so far in the literature. The prevalence of comorbidities is not clear in children with COVID-19. Here, we reported a fatal case of simultaneous pneumonia secondary to SARS-CoV-2and acute liver failure in a 14-year-old boy with liver cirrhosis. &nbsp

Strategic planning, components and evolution in zoonotic diseases frameworks: one health approach and public health ethics

Zoonotic diseases are seen as a major public health concern. Routes of the rapid transmission of zoonotic diseases and the economic damage they cause to communities are all reasons why health institutions and systems need to pay more attention to these diseases. Strategic planning is one of the important tasks of policymakers in every organization and system. It is a very reliable and useful tool for leading all kinds of organizations, including health organizations. Countries with clear policy plans have succeeded in controlling and reducing zoonotic diseases. Such countries used appropriate strategic planning and pursued annual goals to control and prevent diseases. Three important steps (strategy development, strategy implementation and strategy evaluation) should be considered in developing a strategic planning for controlling and prevention of zoonotic diseases. Health systems need to develop strategic planning in order to upgrade their capabilities in combating zoonotic diseases. These programs must be flexible, in line with the one health approach, based on the current needs, and aligned with the new challenges faced with health systems. The strategic planning is directly related to national and international policies, organizational goals and missions, dynamism, degree of complexity, and organizational structure of each country's health system

A policy analysis of agenda-setting of Brucellosis in Iran using multiple streams framework: health policy and historical implications

Background: Brucellosis, a major zoonotic disease, is highly present in Iran, especially in Lorestan province. The aim of this study was to understand the issues related to Brucellosis utilizing the multiple streams framework. Methods: A two-step method was adopted: i) assessment of brucellosis-related documents and ii) interviews with stakeholders. Results: The problem stream was characterized by: 1) high prevalence of the disease, 2) traditional livestock production, 3) unsafe animal slaughtering, 4) centers for the sale and distribution of non-authorized dairy products, 5) raw milk and 6) traditional unsafe dairy products consumption, 7) incomplete livestock vaccination, 8) lack of knowledge of Brucellosis, 9) neighboring countries with high prevalence of Brucellosis, 10) lack of livestock quarantine, and 10) nomadic immigration. The policy stream was characterized by 1) primary healthcare networks, 2) guidelines, 3) medicines, insurance, and 4) diagnostic services. Finally, the political stream was characterized by: 1) support of the University of Medical Sciences, 2) sponsorship by the Ministry of Health and Medical Education, 3) Health transformation plan, and 4) Working Group on Health and Food Security in Lorestan. Conclusion: This study examined the brucellosis-related agenda setting: if different issues are taken into consideration, it can be perceived as a health priority

Universal Health Coverage to counteract the economic impact of the COVID-19 infection

In December 2019, the first case of Coronavirus was identified. The novel virus appears to be highly contagious and is rapidly spreading worldwide, becoming a pandemic. The disease is causing a high toll of deaths. Effective public health response to a new infectious disease is expected to mitigate and counteract its negative impact on the population. However, time and economic-financial constraints, as well as uncertainty, can jeopardize the answer. Appropriate financing of the health system and ensuring equitable access to health services for all can protect individuals against high medical costs, which is one of the most important goals of any health system. Financing profoundly affects the performance of the health system, and any policy that the health system decides to implement or not directly depends on the amount of available funding. Various countries are injecting new funding to cope with the disease and prevent it faster. In addition to psychological support and increased social participation for the prevention, control, and treatment of COVID-19, extensive financial support to governments by the community should be considered. Developed and rich countries should support countries that do not have financial viability. This disease cannot be controlled without international cooperation. The experience of the COVID-19 should be a lesson for further developing universal health coverage in all countries. In addition to promoting equity in health, appropriate infrastructure is provided to address these crises. Governments should make a stronger political commitment to implement this crucial policy fully

Diagnostic Accuracy of Ultrasonography and Radiography in Detection of Pulmonary Contusion; a Systematic Review and Meta-Analysis

Introduction: Ultrasonography is currently being used as one of the diagnostic modalities in various medical emergencies for screening of trauma patients. The diagnostic value of this modality in detection of traumatic chest injuries has been evaluated by several studies but its diagnostic accuracy in diagnosis of pulmonary contusion is a matter of discussion. Therefore, the present study aimed to determine the diagnostic accuracy of ultrasonography and radiography in detection of pulmonary contusion through a systematic review and meta-analysis. Methods: An extended systematic search was performed by two reviewers in databases of Medline, EMBASE, ISI Web of Knowledge, Scopus, Cochrane Library, and ProQuest. They extracted the data and assessed the quality of the studies. After summarization of data into true positive, false positive, true negative, and false negative meta-analysis was carried out via a mixed-effects binary regression model. Further subgroup analysis was performed due to a significant heterogeneity between the studies. Results: 12 studies were included in this meta-analysis (1681 chest trauma patients, 76% male). Pooled sensitivity of ultrasonography in detection of pulmonary contusion was 0.92 (95% CI: 0.81-0.96; I2= 95.81, p<0.001) and its pooled specificity was calculated to be 0.89 (95% CI: 0.85-0.93; I2 = 67.29, p<0.001) while these figures for chest radiography were 0.44 (95% CI: 0.32-0.58; I2= 87.52, p<0.001) and 0.98 (95% CI: 0.88-1.0; I2= 95.22, p<0.001), respectively. Subgroup analysis showed that the sources of heterogeneity between the studies were sampling method, operator, frequency of the transducer, and sample size. Conclusion: Ultrasonography was found to be a better screening tool in detection of pulmonary contusion. Moreover, an ultrasonography performed by a radiologist / intensivist with 1-5MHz probe has a higher diagnostic value in identifying pulmonary contusions
