    Abstract: The underlying cause of death represents the most important information on death certificates. Often, conditions that cannot represent a true underlying cause of death are listed as such. This phenomenon affects the quality of vital statistics and results of studies using cause-specific mortality as endpoints. We aimed at exploring the magnitude and factors associated with the use of heart failure to describe the underlying cause of death. Methods: In this cross-sectional, register based study we linked data from the Norwegian Cause of Death Registry and the Norwegian Patient Registry. We used logistic regression models to analyse the association between external factors and heart failure listed as the underlying cause of death. Results: Heart failure was listed as the underlying cause of death in 3.6% of all deaths. The odds of heart failure increased: (a) by 35% for 5-year increment in age; (b) by 78% for deaths occurring at nursing homes (compared with in-hospital deaths); and (c) by 602% for deaths not followed by an autopsy (compared with those followed by an autopsy). Deceased with a previous hospitalisation with heart failure as the discharge diagnosis had 514% higher odds of having heart failure listed as their underlying cause of death. Of the deceased with heart failure listed as the underlying cause of death, 9.4% did not have any, and 69.2% had only irrelevant additional information for assessing the true underlying cause of death in their death certificates. Conclusions: Heart failure listed as the underlying cause of death was associated with age, place of death, autopsy and previous hospitalisations – all factors that should not influence coding procedures. Better completion of death certificates in accordance with the World Health Organization rules will help reduce the use of heart failure to describe the underlying cause of death.

    Abstract: Aquatic environments and water resources face a variety of risks from numerous sources of pollution. In this paper, we propose a preliminary mechanism for realizing robotic technology practically and cost-effectively for monitoring these pollutions. The presented system is a small robotic fish propelled by a beam of ionic polymer-metal composite (IPMC) artificial muscle that imitates the motion of a small Scorpis Georgiana fish. One of the superiorities of the proposed model is the IPMC actuation mechanism powered by a battery that is charged wirelessly from a solar panel source. This approach enables us to produce a robotic fish that works ceaselessly without being forced to carry the solar panel load. Moreover, we present a method to control the flapping motion of a robotic fish by taking advantage of a tiny Wi-Fi module that yields more working range, bulky data sending, low power consumption, simple programing, and convenient communication for creating a network with other similar robots. All these beneficial characteristics make the proposed structure a promising candidate for detecting pollution on the surface of aquatic environments and sending/recording necessary data in collaboration with desirable sensors. Theoretical considerations support experimental results reported in the paper.

    Non-uniform deformation and curvature identification of ionic polymer metal composite actuators

    Abstract: Modeling and identification of dynamic behavior of ionic polymer metal composites as a widely used smart material is an inevitable work. In this article, unlike other conventional methods that modeled the tip displacement or uniform deformation of the ionic polymer metal composite, we have modeled the nonuniform deformation of the ionic polymer metal composite actuator. Final target of this method is estimation and prediction of a multi-criteria dynamic mathematical model. This dynamic mathematical model has been defined in such a way that all geometrical characteristics, shape, and curvature of it are consistent with the ionic polymer metal composite characteristics in all the time. This model can be useful to extract and predict many geometrical and even physical characteristics of the ionic polymer metal composite such as torque due to the ionic polymer metal composite weight, curvature, and bending angle. Experimental results demonstrate that the proposed method is capable to identify and predict the ionic polymer metal composite nonuniform deformation and curvature trajectory accurately even in a large deformation situation.

    Abstract: Ionic polymer–metal composites are an emerging kind of electroactive polymer actuators, which can bend in response to a relatively low driving voltage. However, to enhance the actuation performance of ionic polymer–metal composites, some of their drawbacks should be considered. One of the most important drawbacks is “back relaxation.” The so-called back relaxation effect means, when a step input voltage is applied to the ionic polymer–metal composite, the conventional bending displacement toward the anode is followed by an unwanted and slow back relaxation toward the cathode. Control-based methods for restraining the ionic polymer–metal composite back relaxation effect are feedback-based schemes which apply significant constraints to dominant applications of ionic polymer–metal composite actuators especially in biomedical applications. In this article, we present an entirely scientific-based mathematical modeling to achieve a practical method for restraining the back relaxation effect in Nafion-based ionic polymer–metal composites, relying on creating a specific pattern on Pt layers of the ionic polymer–metal composites and applying a local Gaussian disturbance to this patterned ionic polymer–metal composites.

    Abstract: Zinc deficiency is one of the most preva- lent micronutrient deficiencies in developing countries, including Iran. The main direct causes of zinc deficiency are insufficient zinc intake, absorption or metabolic disorder, and increase in need during acute growth periods. Objective To determine the prevalence of zinc defi- ciency in preschool boys and girls in urban and rural populations in order to assist policy makers. Children of preschool age (i. e., 6 years old in Iran) were studied because interventions in this age group are believed to result in greater improvement in learning skills once these children enter school. Methods A national cross-sectional study was carried out on 4,374 randomly selected healthy preschool children from Iranian families in 2001. Serum zinc concentration was measured by atomic absorption spectrometry. The cutoff point for zinc deficiency was set at a serum level of 10 μmol/L (65 μg/dL). Results The prevalence of zinc deficiency was esti- mated at approximately 19.3%. The highest preva- lence was seen in the region that includes Sistan and Baluchistan, South Khorasan, and the southeast area of Kerman and the lowest in the region of Boushehr, Hor- mozgan, and South Khoozestan. The prevalence of zinc deficiency was significantly higher in rural areas than in urban areas. No significant difference in prevalence was seen between boys and girls. Conclusions In the long run, nutritional security and increased access to and intake of foods with high levels of zinc are the most sustainable strategies to overcome zinc deficiency. Fortification of staple foods, improved qual- ity of traditional bread, and supplementation for at-risk population groups are considered short- and mid-term nterventions. Nutrition education and behavioral change may be long-term strategies.

    Abstract: Skin diseases can have high morbidity that can be costly to society and individuals. To date, there has been no comprehensive assessment of the burden of skin disease in Canada. Objectives To evaluate the burden of 18 skin and subcutaneous diseases from 1990 to 2017 in Canada using the Global Burden of Disease (GBD) data. Methods The 2017 GBD study measures health loss from 359 diseases and injuries in 195 countries; we evaluated trends in population health in Canada from 1990 to 2017 using incidence, prevalence, mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs). Data are presented as rates (per 100 000), counts, or percent change with the uncertainty interval in brackets. Results From 1990 to 2017 for all skin diseases, DALY rates increased by 8% to 971 per 100 000 (674-1319), YLD rates increased by 8% to 897 per 100 000 (616-1235), YLL rates increased by 4% to 74 per 100 000 (53-89), and death rates increased by 18% to 5 per 100 000 (3-6). DALY rates for melanoma increased by 2% to 54 per 100 000 (39-68), for keratinocyte carcinoma by 14% to 17 per 100 000 (16-19), and for skin and subcutaneous disease by 8% to 900 per 100 000 (619-1233). The observed over expected ratios were higher for skin and subcutaneous disease (1.37) and keratinocyte carcinoma (1.17) and were lower for melanoma (0.73). Conclusions The burden of skin disease has increased in Canada since 1990. These results can be used to guide health policy regarding skin disease in Canada.
