Iranian Journal of Public Health Tehran University of Medical Sciences en-US Iranian Journal of Public Health 2251-6085 Theoretical and Practical Principles on Nanoethics: A Narrative Review Article <p>&nbsp;</p> <p><strong>Abstract</strong></p> <p><strong>Background:</strong> Interests in nanotechnology and its application in medical research, diagnosis, and treatment of diseases continuously grow. The study identified the theoretical and practical principles of ethics in developed countries’ nanomedical research to be used as the first step of development of a national nanoethics standard or guideline in Iran and developing countries.</p> <p><strong>Methods:</strong> The present study was done between 2012-2016 in Ethics and Law Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran, which comprised a literature review and a comparative study to describe and compare the nanoethics situation and considerations of nanoethics in Australia, Canada, and USA.</p> <p><strong>Results:</strong> The main ethical considerations in the three countries contain two major categories, including firstly, the nature of nanoparticles such as its diversity, rapid development of new and not well-defined nanoproducts and particles and unpredictable side effects of such nanoparticles; and secondly, the application of developed nanoparticles in areas such as justice, privacy protection, patient-physician relations, etc.</p> <p><strong>Conclusion:</strong> It is controversial to develop an independent nanoethics standard or codes; however, national priorities and concerns, as well as specific nanoethics considerations, should be investigated before deciding to create such standards in each country. Overall, careful considerations have to take into account the justice, privacy protection, the inherent risks of nanomaterials and their possible side effects on patients and other study subjects, as well as considering characteristics of new developed nanoproducts and particles.</p> <p><strong>&nbsp;</strong></p> <p>&nbsp;</p> Saeed BIROUDIAN Mahmoud ABBASI Mehrzad KIANI ##submission.copyrightStatement## 2019-10-04 2019-10-04 48 10 1760 1767 Comparative Analyses of the Dominant and Non-Dominant Up-per Limbs during the Abduction and Adduction Motions <p>&nbsp;</p> <p><strong>Background:</strong> Asymmetry in repeated motion may lead to dyskinesia through imbalance in the involved musculoskeletal structures. The dominance sides are also involved greater movement involvement over the non-dominant sides. The upper limbs with multiple joints and largest range of motion are prone for unsynchronized coordination. Natural movement analysis is required for application to everyday activities.</p> <p><strong>Methods:</strong> Thirty participants were first recruited from Inha University, Incheon, Korea in 2019. Twenty subjects were assessed for comparisons of asymmetrical motion between the dominant and non-dominant arms during the abduction and adduction lateral raises after excluding ten subjects for shoulder pain and left-handedness.</p> <p><strong>Results:</strong> The abduction and adduction motions of the bilateral arms were compared for the angular locations, velocity, and acceleration for every 10 degrees. The angular locations of the dominant side occurred significant earlier in the initial (10°, 20°, 30°) phase and later in the last (10°, 20°) phase of abduction and adduction in comparison to the non-dominant side (<em>P</em>&lt;.05). The angular accelerations of the dominant side were also significantly greater during the initial phase (0°, 10°, 30°) and last phase (0°, 10°, 30°) (<em>P</em> &lt;.05). The angular velocities were significantly greater during the later phase (40, 50, 60°) of abduction (<em>P</em> &lt;.04).</p> <p><strong>Conclusion:</strong> Comparative dominant side indicated more controlled movements through the range of motion with greater stability in angular acceleration and deceleration especially during the initial and last phase of abduction and adduction, respectively. Training for control of the specific angular points should be considered during abduction and adduction motions to prevent asymmetry of the bilateral arms.</p> <p><strong>&nbsp;</strong></p> <p>&nbsp;</p> Haemi JEE Jaehyun PARK ##submission.copyrightStatement## 2019-10-04 2019-10-04 48 10 1768 1776 Application Effects of Whole Course High-Quality Nursing on Patients with Liver Cancer during Radiotherapy <p><strong>Abstract</strong></p> <p><strong>Background:</strong> To explore the application effects of whole course high-quality nursing on patients with liver cancer during radiotherapy.</p> <p><strong>Methods:</strong> One hundred and five patients with liver cancer who received radiotherapy in Liaocheng People’s Hospital, Liaocheng, China from March 2010 to February 2012 were selected and divided into a control group (42 cases with routine nursing) and an experimental group (63 cases with whole course high-quality nursing).

Predictably, the disadvantaged and poor population groups in both developing and developed countries have high rate of malign disease. The aim of this study was to evaluate the prevalence of head and neck cancers (HNCs) and to compare them between Syrian and Turkish population.</p> <p><strong>Methods:</strong> A total of 4570 patients confirmed to have HNC histopathologically from Hatay Mustafa Kemal University Hospital Pathology report archive were retrospectively evaluated. Among them, 452 were Syrian patients while 4118 were Turkish patients. Data were collected from 2010 to 2017. Gender and age information were taken from medical records. According to the pathological results, HNCs were classified.</p> <p><strong>Results:</strong> In 474 patients, HNCs were inscriptived, of which 317 were in males and 157 in females aged 23–80 years with histologically approved cancer of head and neck area. Overall, 100 were Syrian patients while 374 were Turkish patients. In both Syrian and Turkish patients, the most observed HNC was squamous cell carcinoma (SCC).</p> <p><strong>Conclusion:</strong> Nowadays, the prevalence of cancer is higher because of the excessive consumption of alcohol, tobacco, chewing, and smoking. For the higher cancer incidence in Syrian refugees, we thought that the impact of war such as stress may have been effective as well as the known several etiologic factors of cancer. For the increased risk of cancer, the early diagnosis of this become more important.</p> <p>&nbsp;</p> Gozde SERİNDERE Behiye BOLGUL Didar GURSOY Sibel HAKVERDİ Nazan SAVAS ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1810 1816 Expression of miR-664-3p in Osteosarcoma and Its Effects on the Proliferation and Apoptosis of Osteosarcoma Cells <p><strong>Abstract</strong></p> <p><strong>Background:</strong> To explore the expression level of miR-664-3p in osteosarcoma and its effects on the proliferation and apoptosis of osteosarcoma cells.</p> <p><strong>Methods:</strong> Specimens of osteosarcoma tissues were collected from 41 cases undergoing surgical treatment in the Orthopedics Department of Wuhan Puai Hospital, Wuhan, China from January 2015 to February 2018. Another 40 cases of normal bone tissue were collected. The expression of miR-664-3p were detected using quantificational real-time polymerase chain reaction. miR-664-3p mimics, miR-664-3p inhibitor and miR-664-3p negative control (NC) were used to transfect U2-OS, which were named as mimics group, inhibitor group and NC group, respectively. MTT assay was adopted to detect the effects of microRNA-664-3p on the proliferation of U2-OS after 24, 48, 72, 96 and 120 hours of transfection. Flow cytometry was applied to measure the apoptosis rate of U2-OS after miR-664-3p transfection. Finally, Western Blot was employed to detect the expression of proteolipid protein 2 (PLP2).</p> <p><strong>Results:</strong> The total apoptosis rate of cells in the inhibitor group was obviously higher than those in the mimics group and the NC group (<em>P</em>&lt;0.001). The relative expression level of PLP2 in the inhibitor group was significantly lower than those in the mimics group and the NC group (<em>P</em>&lt;0.001).</p> <p><strong>Conclusion:</strong> MiR-664-3p may be involved in the occurrence and development of osteosarcoma, and can regulate the proliferation and apoptosis of U2-OS cells, and the expression of PLP2. Besides, miR-664-3p may become a novel molecular biological indicator for the diagnosis, targeted treatment and prognosis assessment of osteosarcoma.</p> <p>&nbsp;</p> Ye LI Jie TANG Yong HU Yonghai PENG Junwen WANG ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1817 1826 Association of LOXL1 Gene Polymorphisms with Exfoliation Glaucoma Patients <p><strong>Abstract</strong></p> <p><strong>Background:</strong> Pseudoexfoliation syndrome (XFS) is pathogenetically related to exfoliative glaucoma (XFG), which is the most common type of secondary glaucoma. We aimed to investigate the relationship between <em>LOXL1</em> SNPs (rs1048661, rs3825942) and XFS and/or XFG in a cohort of Iranian subjects.</p> <p><strong>Methods:</strong> This cross-sectional study investigated possible association between LOXL1 gene polymorphisms and exfoliative glaucoma in Northeastern part of Iran between May 2014 and May 2015. Sixty unrelated XFS/XFG patients, as well as 40 control subjects, were studied by direct sequencing. In fifteen senile cataract patients without glaucoma and fifteen patients with coexisting XFG and cataract, capsulorhexis specimen of the anterior lens capsule was used to evaluate <em>LOXL1</em> gene transcripts by Real-Time PCR technique. We analyzed the results for allele frequencies and haplotype association and investigated the relative gene expression.</p> <p><strong>Results:</strong> Significant associations between the rs382594 SNP and XFG and between rs1048661 SNP and XFG were observed (<em>P</em>&lt;0.05 for both). The frequency of the G allele in the exonic SNP (rs1048661) appeared to be higher in XFS or XFG patients compared to control subjects (<em>P</em>= 0.0497). Moreover, in the rs3825942 SNP, the G allele was more frequent in XFS/XFG patients compared to control subjects (<em>P</em>=0.0016). The highest cumulative frequency was for the GG haplotype. GG haplotype was associated with increased risk of XFG compared to the rs1048661 G/T and rs3825942 G/A haplotypes. <em>LOXL1</em> mRNA expression was not statistically significantly different between XFS/XFG and control subjects.</p> <p><strong>Conclusion:</strong> We reported the <em>LOXL1</em> gene polymorphism in an Iranian XFS/XFG cohort.

We aimed to estimate the prevalence and complications of substance use in teenagers referring to a tertiary hospital following intoxication.</p> <p><strong>Methods:</strong> In a cross-sectional study between 2012 and 2013 in Loghman Hakim Hospital, Tehran, Iran, sixteen substances were checked in teenagers referring due to poisoning. They divided into two groups of young (13 to &lt;16 yr; group 1) and old-teenagers (16 to 19 yr; group 2). History of lifetime substance use and drug use within the week prior to admission were recorded.</p> <p><strong>Results:</strong> Mean (range) age of young teenagers was 14.5±0.6 [13, 15] and 17.7±1.1 [16, 19] in old-teenagers with female predominance. Of 264 teenagers, four in group 1 and 27 in group 2 were admitted due to drug overdose. Six and 69 patients in groups 1 and 2 claimed that they had used some kind of substance in the week prior to admission. Twenty (37%) and 106 (50.5%) patients in the young and old-teenager groups were defined as drug users and rates of unreported substance use were 27.8% (15 cases) and 23.8% (50 cases) respectively. Ninety-six substance users (36.4%) had referred due to poisonings other than recreational intoxication (<em>P</em>&lt;.001).

We assessed the reform by changes in variables representing distribution of health payments and catastrophic expenditures.</p> <p><strong>Methods:</strong> Using data from households’ income-expenditure survey, this study computed the financial variables, representing poverty line and households at poor state, household’s catastrophic health expenditure, fairness in financial contribution (FFC) index, and household’s impoverishment state, in the years 2010-2016, in urban and rural areas. The variables were computed by special software designed for this study, based on C-Sharp(C#) programming language, with yearly data on more than 38000 households, each with 1072 information sources.</p> <p><strong>Results:</strong> The food share-based poverty line after sharp rise in 2010-2013, in 2014-2016 raised slowly, and the average percent of households facing catastrophic health expenditure, after sharp rise in 2011-2013, left at 3.25 in 2014-2015 and raised to 3.45 in 2016. The average FFC index remained at 0.839 to 0.837 in 2013-2016. However, interestingly, the average percent of households impoverished after out-of-pocket payments improved from 1.36 to 0.912 in 2013-2016.</p> <p><strong>Conclusion:</strong> In three years of health reform, the major impact of reform was considerable improvements in the rate of the impoverished after out-of-pocket payments.

The aim of this study was to determine the spatial distribution of cutaneous leishmaniasis in northeastern Iran.</p> <p><strong>Methods:</strong> In this cross-sectional study, information on positive cases of cutaneous leishmaniasis in the three provinces located in northeastern Iran during Jul 2011 to Jul 2017 was obtained from the Iranian Ministry of Health. Based on the postal address of each case, the geographical coordinates of each patient were determined for spatial analysis of cutaneous leishmaniasis. For spatial analysis, Moran’s index autocorrelation and Kriging interpolation method were used in GIS software.</p> <p><strong>Results:</strong> Moran’s index autocorrelation showed that spatial distribution of disease incidence in the study area was cluster pattern (Z-score &gt; 1). In addition, Kriging interpolation method revealed that 90% of southern parts of North Khorasan province and northern parts of Razavi Khorasan Province formed hot spots.</p> <p><strong>Conclusion:</strong> The CL incidence is a function of spatial and geographical trends. In addition, spatial trends in the disease incidence distribution indicate that it is not greatly increased or decreased from one area to another. It appears as hot spots areas.

The aim of this study was to develop a new sample preparation method with high accuracy and validity, simplicity and short retention time for determination of malathion.</p> <p><strong>Methods:</strong> Dispersive liquid-liquid micro-extraction (DLLME) technique coupled with high-performance liquid chromatography equipped with ultraviolet detector (HPLC-UV) developed for trace extraction and determination of malathion pesticide in human urine samples. This study was done in 2017 at Tehran University of Medical Sciences, Tehran, Iran. One variable at a time (OVAT) method was used to optimize parameters affecting the malathion extraction. Different parameters such as extraction solvent, disperser solvent, and volume of the extraction solvent, volume of the disperser solvent, centrifugation time and speed, salt addition, and sample pH were studied and optimized.</p> <p><strong>Results:</strong> Under the optimized conditions, the limit of detection and enrichment factor of the method were 0.5 µg L<sup>-1</sup> and 200, respectively. The calibration curve was linear in the concentration range of 2-250 µg L<sup>-1</sup>. The relative standard deviation for six replicate experiments at 200 µg L<sup>-1</sup> concentration was less than 3%. The relative recoveries of spiked urine samples were 96.3%, 101.7% and 97.3% at three different concentration levels of 50, 200 and 1000 µg L<sup>-1</sup>, respectively.</p> <p><strong>Conclusion:</strong> DLLME procedure was successfully developed for the extraction of malathion from human urine samples. Compared to other extraction techniques, the proposed procedure had some advantages such as shorter extraction time, better reproducibility, and higher enrichment factor.</p> <p><strong>&nbsp;</strong></p> <p>&nbsp;</p> Maryam RAMIN Monireh KHADEM Fariborz OMIDI Mehran POURHOSEIN Farideh GOLBABAEI Seyed Jamaleddin SHAHTAHERI ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1893 1902 Trends of HIV/AIDS Phenomenon Dynamics in Romania from 2017-2027 <p><strong>Abstract</strong></p> <p><strong>Background:</strong> HIV infection remains of major public health importance in all world and in Romania. In Romania there are a large number of long-term survivors coming from the 1987-1990 generation, the circumstances are due to the fact that an increased number of HIV-infected persons receive a specific therapy.</p> <p><strong>Methods:</strong> The study was conducted using sociological analysis methods such as comparative analysis, statistical analysis, and with the help of the method of regression analysis, to capture the dynamics of the HIV / AIDS phenomenon in Romania, as well as forecasting the dynamics of the phenomenon over the next decade.</p> <p><strong>Results:</strong> This longitudinal analysis of the statistical data provided by the Matei Bals Institute of Romania during the period 2004-2016, shows a progressive increase 1.4 times higher in 2016 compared to 2004, the prediction of the extension of the HIV / AIDS phenomenon for the period 2017-2027, in Romania being almost constant. Regarding the prognosis of the number of persons affected by HIV / AIDS in Romania, for the next 10 years an upward dynamic is predicted with an increasing annual rate of 506 new persons taken into evidence. As the prediction function shows, the trend the access to treatment is increasing for the next decade. After 2006 in Romania, the deaths dynamics is an exponential decreasing one, keeping the same rate of decrease, until 2015.</p> <p><strong>Conclusion:</strong> The HIV/AIDS pandemic has changed considerably in the past 27 years. AIDS incidence and mortality in industrialised countries have fallen, and paediatric HIV disease has almost been eliminated as a public health issue, largely through antiretroviral drugs.</p> <p><strong>&nbsp;</strong></p> <p>&nbsp;</p> Andrioni FELICIA ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1903 1909 Brief Report of Variants Detected in Hereditary Hearing Loss Cases in Iran over a 3-Year Period <p><strong>Abstract</strong></p> <p><strong>Background:</strong> Diagnosis of hereditary hearing loss (HHL) as a heterogeneous disorder is very important especially in countries with high rates of consanguinity where the autosomal recessive pattern of inheritance is prevalent. Techniques such as next-generation sequencing, a comprehensive genetic test using targeted genomic enrichment and massively parallel sequencing (TGE + MPS), have made the diagnosis more cost-effective. The aim of this study was to determine HHL variants with comprehensive genetic testing in our country.</p> <p><strong>Methods:</strong>&nbsp; Fifty <em>GJB2</em> negative individuals with HHL were referred to the <a href="">Kariminejad-Najmabadi Pathology and Genetics Cente</a>r, Tehran, one of the reference diagnostic genetic laboratories in Iran, during a 3-year period between 2014 and 2017. They were screened with the OtoSCOPE test, the targeted genomic enrichment and massively parallel sequencing (TGE + MPS) platform after a detailed history had been taken along with clinical evaluation.</p> <p><strong>Results:</strong> Among 32 out of 50 <em>GJB2</em> negative patients (64%), 34 known pathogenic and novel variants were detected of which 16 (47%) were novel, identified in 10 genes of which the most prevalent were <em>CDH23, MYO7A </em>and <em>MYO15A.</em></p> <p><strong>Conclusion:</strong> These results provide a foundation from which to make appropriate recommendations for the use of comprehensive genetic testing in the evaluation of Iranian patients with hereditary hearing loss.</p> <p>&nbsp;</p> Niloofar BAZAZZADEGAN Raheleh VAZEHAN Mahsa FADAEE Zohreh FATTAHI Ayda ABOLHASSANI Elham PARSIMEHR Zahra KALHOR Mehrshid FARAJI ZONOOZ Fatemeh AHANGARI Shima DEHDAHSI Farshide SAMIEE Payman JAMALI Haleh HABIBI Younes NOURIZADEH Shokouh MAHDAVI Maryam BEHESHTIAN Ariana KARIMINEJAD Richard JH SMITH Hossein NAJMABADI ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1910 1915 Outbreak of Foodborne Botulism Associated with Improperly Earthenware Cheese (Koupé): A Case Report <p><strong>Abstract</strong></p> <p>Here we report the consumption of traditional cottage cheese (Koupé) in western Iran, as a new way of transmission of botulism. All the patients (a nine member family) had at least two specific symptoms of botulism. Given the clinical symptoms and contact history, anti-toxins were injected in the early hours of hospital admission. On Jan 27, 2017, three patients clinically suspected of foodborne botulism were referred to the hospital in Sanandaj, western Iran from their local hospital in Baneh, western, Iran. Because of the worsening of clinical conditions, a 34-yr-old man with both gastrointestinal and neurological symptoms was admitted to the ICU, while other family members were treated in the infectious diseases ward of the hospital. The disease was diagnosed through isolating toxin A from the cheese and testing the serum sample of one of the patients. This case of botulism showed that traditional Koupé cheese could cause foodborne botulism. Hence, it is necessary to train and inform people about how to process and keep the cheese to prevent similar cases.</p> <p>&nbsp;</p> Parshang FAGHIH SOLAYMANI Ardeshir RAHIMZADEH Farideh MOSTAFAVI ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1916 1919 Square Dance the Key Factor of the Elevating Prevalence of Physical Activity in China <p>No Abstract</p> Chao DENG Ruibing FENG Lihong KONG ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1920 1921 Effects of Physical and Social Activity on Physical Health and Social Inclusion of Elderly People <p>No Abstract</p> Stevo POPOVIC Bojan MASANOVIC ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1922 1923 Differences in Skin Health Outcomes according to Physical Activity Level among Korean Female College Students <p>No Abstract</p> Jeong-Hyun LEE Yeona KIM Wi-Young SO ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1924 1926 Prevalence, Trends and Associated Risk Factors of Over-weight/Obesity among Rural-to-Urban Migrant Children in China <p>No Abstract</p> Jinkui LU Yongsheng XU Jianming XIANG ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1927 1929 Application of Continuing Care in Patients with Mild Cerebral Hemorrhage <p>No Abstract</p> Min ZHANG Yang YU Yujun CHEN Guihong FAN ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1930 1932 Neuroscience as an Insightful Decision Support Tool for Sustainable Development <p>No Abstract</p> Rui ZHAO ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1933 1934 Disparities and Discrimination against People with HIV/AIDS by Healthcare Providers in Iran <p>No Abstract</p> Ahmad KALATEH SADATI Kamran BAGHERI LANKARANI ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1935 1936 Effects of Opium Use on Cardiovascular Mortality: A Critical Appraisal of a Topic <p>No Abstract</p> Seyyed Ali MOEZI Nahid AZDAKI Toba KAZEMI Hamid Reza MASHREGHI MOGHADDAM Neda PARTOVI Fatemeh HAMIDI Nazanin HANAFI-BOJD Majid JAFARNEJAD Samaneh NAKHAEE ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1937 1939 Detection of Heroin and Noscapine in Bile Specimen in a Body Packer <p>No Abstract</p> Nahid NAJAFI Mahmoud MONTAZERI ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1940 1941 Prevalence of Malnutrition and Its Related Factors among Pre-School (2-6 Years) Children in the Neighborhood of Chahestaneha, Bandar-Abbas, Iran <p>No Abstract</p> Kabir Ozigi ABDULLAHI Fatima Mahmud MUHAMMAD Kourosh HOLAKOUIE-NAIENI Ahmad KHOSRAVI Fahad Saqib LODHI hang Abdullah KAREEM Hasnain SABAHAT Sami Najmaddin SAEED Mohammad Ali HOSSEINI ##submission.copyrightStatement## 2019-10-05 2019-10-05 48 10 1942 1944
