A lightweight and secure multilayer authentication scheme for wireless body area networks in healthcare system

Wireless body area networks (WBANs) have lately been combined with different healthcare equipment to monitor patients' health status and communicate information with their healthcare practitioners. Since healthcare data often contain personal and sensitive information, it is important that healthcare systems have a secure way for users to log in and access resources and services. The lack of security and presence of anonymous communication in WBANs can cause their operational failure. There are other systems in this area, but they are vulnerable to offline identity guessing attacks, impersonation attacks in sensor nodes, and spoofing attacks in hub node. Therefore, this study provides a secure approach that overcomes these issues while maintaining comparable efficiency in wireless sensor nodes and mobile phones. To conduct the proof of security, the proposed scheme uses the Scyther tool for formal analysis and the Canetti–Krawczyk (CK) model for informal analysis. Furthermore, the suggested technique outperforms the existing symmetric and asymmetric encryption-based schemes

An Evaluation of Space Use Efficiency in Residential Houses, Kabul City

Space efficiency is one of the significant segments of building that requires consideration. This study focuses on the evaluation of space use efficiency in existing residential buildings and seeks to look at the current space use practices in interior design. The study analyzes (1) how the interior space of buildings is used. (2) Considering the architectural guidelines to evaluate the space deficit of buildings. Therefore, the study takes the form of a literature review, with direct observation used for data collection. A total of six residential houses were observed, with interior space dimensions and areas measured using measurement tools. Comparative analysis is a technique used for data analysis. The findings of this study revealed that most residential buildings are not meeting space use regulations and standards ascribed to not considering the interior design process and governmental building guidelines. Most of the constructed buildings were not properly designed, the architectural design procedure was not considered. The study concluded with suggestions for raising public awareness about architectural design significance, imposing governmental regulation and building laws, and eradicating nonengineered construction in the city. Findings will serve clients and municipalities; policymakers should concentrate on public awareness and imposing building laws to ensure affordable houses in Kabul city

Attitudes among young adults in Palestine about peers with substance use problems: Challenges and opportunities for community intervention design

Social reintegration is necessary to support people in recovery from addiction, but it is often difficult in Palestine due to stigma. Bin Hussein’s instrument for measuring receptivity to social reintegration in various contexts in Saudi Arabia was employed for comparison in the West Bank. Data were collected in 2013 at Al-Quds University at the Abu Dis campus. More than half of the respondents have moderate attitudes toward social reintegration of people in recovery. There were no significant relationships between perceptions about social reintegration and gender, age, year in college, area of academic focus, and form of residence. Implications are discussed.The author(s) received no financial support for the research, authorship, and/or publication of this article

Kidney Sparing Huge Retroperitoneal Liposarcoma

Retroperitoneal Liposarcoma is a rare malignant tumor of mesenchymal origin and is the most common type of soft tissue sarcoma with a rate of 3-4 individuals for every million people. It usually appears between 50-70 years of age, and the proportion between the sexes are equal. Due to their retroperitoneal location they are much more difficult to diagnose and often came into notice as incidental findings when they became very large or start to invade adjacent organs. The Gold Standard treatment of Retroperitoneal Liposarcoma is resection as per the European Society for Medical Oncology guideline (ESMO). Chemotherapy and radiotherapy can be offered as palliative treatment because of the extremely massive size of primary tumors rendering them inoperable as well as in high-grade cases. In this case study, a case of 40 years old male was reported, who underwent surgical resection of retroperitoneal liposarcoma. The complete resection of the mass was successful and the kidney was spared in the procedure. Keywords: Retroperitoneal Liposarcoma; Multimodality Treatment; Chemotherapy; Radiotherapy

Halal Food Crime in Malaysia: An Analysis On Illegal Meat Cartel Issues

Malaysia is a known for its high level of sensitivity in the halal and haram aspects. Its status as an international halal hub reflects the sustainable halal ecosystem in the country, supported by the sensitivities of the government, industry and consumers. Unfortunately, there are irresponsible parties who make halal food a medium of crime. Thus, various food crime issues rise such as food crime, food fraud, food adulteration, food terrorism and cases that cover it. Accordingly, the objective of this article is to target the analysis of food crime issues in Malaysia, focusing on the issue of illegal meat cartels. In addition, various causative factors have been put forward, as well as modern technological alternatives as practical solutions. Data were analysed in a qualitative approach, in which data were collected through document analysis from various primary and secondary sources. As a result, the issue of illegal cartel meat has betrayed all consumers in Malaysia. The government needs to empower halal control in the country, including making practical use of the Industrial Revolution 4.0 era technology

Mapping 123 million neonatal, infant and child deaths between 2000 and 2017

Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2—to end preventable child deaths by 2030—we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000–2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that had attained rates of 25 or fewer child deaths per 1,000 live births by 2017, and that 58% of child deaths between 2000 and 2017 in these countries could have been averted in the absence of geographical inequality. This study enables the identification of high-mortality clusters, patterns of progress and geographical inequalities to inform appropriate investments and implementations that will help to improve the health of all populations

Global, regional, and national comparative risk assessment of 84 behavioural, environmental and occupational, and metabolic risks or clusters of risks for 195 countries and territories, 1990–2017 : a systematic analysis for the Global Burden of Disease Study 2017

Background: The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 comparative risk assessment (CRA) is a comprehensive approach to risk factor quantification that offers a useful tool for synthesising evidence on risks and risk outcome associations. With each annual GBD study, we update the GBD CRA to incorporate improved methods, new risks and risk outcome pairs, and new data on risk exposure levels and risk outcome associations. Methods: We used the CRA framework developed for previous iterations of GBD to estimate levels and trends in exposure, attributable deaths, and attributable disability-adjusted life-years (DALYs), by age group, sex, year, and location for 84 behavioural, environmental and occupational, and metabolic risks or groups of risks from 1990 to 2017. This study included 476 risk outcome pairs that met the GBD study criteria for convincing or probable evidence of causation. We extracted relative risk and exposure estimates from 46 749 randomised controlled trials, cohort studies, household surveys, census data, satellite data, and other sources. We used statistical models to pool data, adjust for bias, and incorporate covariates. Using the counterfactual scenario of theoretical minimum risk exposure level (TMREL), we estimated the portion of deaths and DALYs that could be attributed to a given risk. We explored the relationship between development and risk exposure by modelling the relationship between the Socio-demographic Index (SDI) and risk-weighted exposure prevalence and estimated expected levels of exposure and risk-attributable burden by SDI. Finally, we explored temporal changes in risk-attributable DALYs by decomposing those changes into six main component drivers of change as follows: (1) population growth; (2) changes in population age structures; (3) changes in exposure to environmental and occupational risks; (4) changes in exposure to behavioural risks; (5) changes in exposure to metabolic risks; and (6) changes due to all other factors, approximated as the risk-deleted death and DALY rates, where the risk-deleted rate is the rate that would be observed had we reduced the exposure levels to the TMREL for all risk factors included in GBD 2017. Findings: In 2017,34.1 million (95% uncertainty interval [UI] 33.3-35.0) deaths and 121 billion (144-1.28) DALYs were attributable to GBD risk factors. Globally, 61.0% (59.6-62.4) of deaths and 48.3% (46.3-50.2) of DALYs were attributed to the GBD 2017 risk factors. When ranked by risk-attributable DALYs, high systolic blood pressure (SBP) was the leading risk factor, accounting for 10.4 million (9.39-11.5) deaths and 218 million (198-237) DALYs, followed by smoking (7.10 million [6.83-7.37] deaths and 182 million [173-193] DALYs), high fasting plasma glucose (6.53 million [5.23-8.23] deaths and 171 million [144-201] DALYs), high body-mass index (BMI; 4.72 million [2.99-6.70] deaths and 148 million [98.6-202] DALYs), and short gestation for birthweight (1.43 million [1.36-1.51] deaths and 139 million [131-147] DALYs). In total, risk-attributable DALYs declined by 4.9% (3.3-6.5) between 2007 and 2017. In the absence of demographic changes (ie, population growth and ageing), changes in risk exposure and risk-deleted DALYs would have led to a 23.5% decline in DALYs during that period. Conversely, in the absence of changes in risk exposure and risk-deleted DALYs, demographic changes would have led to an 18.6% increase in DALYs during that period. The ratios of observed risk exposure levels to exposure levels expected based on SDI (O/E ratios) increased globally for unsafe drinking water and household air pollution between 1990 and 2017. This result suggests that development is occurring more rapidly than are changes in the underlying risk structure in a population. Conversely, nearly universal declines in O/E ratios for smoking and alcohol use indicate that, for a given SDI, exposure to these risks is declining. In 2017, the leading Level 4 risk factor for age-standardised DALY rates was high SBP in four super-regions: central Europe, eastern Europe, and central Asia; north Africa and Middle East; south Asia; and southeast Asia, east Asia, and Oceania. The leading risk factor in the high-income super-region was smoking, in Latin America and Caribbean was high BMI, and in sub-Saharan Africa was unsafe sex. O/E ratios for unsafe sex in sub-Saharan Africa were notably high, and those for alcohol use in north Africa and the Middle East were notably low. Interpretation: By quantifying levels and trends in exposures to risk factors and the resulting disease burden, this assessment offers insight into where past policy and programme efforts might have been successful and highlights current priorities for public health action. Decreases in behavioural, environmental, and occupational risks have largely offset the effects of population growth and ageing, in relation to trends in absolute burden. Conversely, the combination of increasing metabolic risks and population ageing will probably continue to drive the increasing trends in non-communicable diseases at the global level, which presents both a public health challenge and opportunity. We see considerable spatiotemporal heterogeneity in levels of risk exposure and risk-attributable burden. Although levels of development underlie some of this heterogeneity, O/E ratios show risks for which countries are overperforming or underperforming relative to their level of development. As such, these ratios provide a benchmarking tool to help to focus local decision making. Our findings reinforce the importance of both risk exposure monitoring and epidemiological research to assess causal connections between risks and health outcomes, and they highlight the usefulness of the GBD study in synthesising data to draw comprehensive and robust conclusions that help to inform good policy and strategic health planning
