44 in 2015 to 984 and 2.94 in 2017. In this period, the number of citations of the past 5-year publications was 4355 according to Scopus database. The proportions of these centers' high-quality publication (Q1) and international collaborations per published articles were 14.8 and 8.25. In ranking, the first to third ranks were occupied by SDH research centers of Kermanshah, Kurdistan, and Qazvin Universities of Medical Sciences. Conclusion Although knowledge production seems desirable in mentioned research centers, it is essential to create a virtual research network to increase intersectoral collaboration and develop strategies to solve the puzzle of gathering evidence on the social determinants affecting health inequities.Background Cardiac echocardiography and cardiac ECG-gated single-photon emission computed tomography (SPECT) are the most common modalities for left ventricle (LV) volumes and function assessment. The temporal resolution of SPECT images is limited and an ECG provides better temporal resolution. This study investigates the impact of frame numbers on images in terms of qualitative and quantitative assessments. Methods In this study, 5 patients underwent echocardiography and cardiac ECG-gated SPECT imaging, and 5 standard views of the LV were recorded to determine LV walls boundaries and volumes. Also, 2 original images with 8 frames and 16 frames per cardiac cycle were recorded simultaneously in a single gantry orbit. Using the data extracted from the LV model, 8 extra new frames were created with interpolation between existing frames of the original 8-frame image. Three series of images (8 and 16 original and 16 interpolated) were reconstructed separately. LV volumes and ejection fraction (EF) were calculated using Quantitative Gated SPECT (QGS) software. Results Compared to the original 8-frame gating, original 16-frame gated images resulted in larger end-diastole volume (EDV) (mean ± SD 68.6 ± 27.11 mL vs 66.2±25.41 mL, p less then 0.001), smaller end-systole volume (ESV) (mean ± SD 24.6±8.7 mL vs 26±7.3 mL, p less then 0.001), and higher EF (64% vs 60.2%, p less then 0.001). The results for the interpolated series were also different from the original images (closer to the original 16-frame series rather than 8-frame). Conclusion Changing the frame number from 8 to 16 in cardiac ECG-gated SPECT images caused a significant change in LV volumes and EF. Frame interpolation with sophisticated algorithms can be used to improve the temporal resolution of SPECT images.Background Measuring background radiation (BR) is highly important from different perspectives, especially from that of human health. This study was conducted to measure BR in the southeast of Iran. Methods BR was measured in Hormozgan and Sistan-Bluchestan provinces using portable Environmental Radiation Meter Type 6- 80 detector. The average value was used to calculate the absorbed dose rate and indoor annual effective dose (AED) from BR. In addition, excess lifetime cancer risk (ELCR) was evaluated. Results The results showed that the maximum and minimum absorbed dose rates were 71.9 and 34.2 nGy.h-1 in Abomoosa and Minab in Hormozgan province and 90.0 and 47.8 nGy.h-1 in Zahedan and Chabahar in Sistan-Bluchestan province, respectively. Data indicated that these areas had a lower BR level compared with the worldwide level. The ELCR from indoor AED was larger compared with the worldwide average of 0.29 × 10-3. Conclusion This study provided a reference for designing and developing specific regional surveys associated with the measurement of natural BR in the southeast of Iran.Although there are many important concerns related to coronavirus disease-19 (COVID-19), ethical issues should remain the top priority since the humanistic dimension of the recent pandemic is of prime importance. This short commentary highlights some ethical concerns related to (COVID-19). Political misuse, caring for older adults, and spread of harmful information are the 3 main issues that are addressed. It is hoped that those who can influence communities at large consider these issues for better public's health.Background The worldwide emergence and rapid expansion of COVID-19 emphasizes the need to assess the knowledge gap and to predict the disease-related behaviors and reactions during this epidemic. Methods and design COVID19 Population Survey of Iran (COPSIR) is a repeated cross sectional survey that will be conducted in 8 waves. In each wave, 515 Iranian adults aged 18 years or older will be randomly selected and interviewed by phone. The study waves will be performed at approximately weekly intervals. The survey tool is adapted from COSMO (COVID-19 Snapshot MOnitoring) study. This study will provide information on trends of knowledge, risk perception, preventive behaviors, psychological problems, essential needs, and public trust among Iranian adults during COVID-19 epidemic. Discussion The key findings of each wave will be immediately reported to the National Headquarters for Coronavirus Control to set better policies for disease control and prevention. Moreover, if a message is extracted from the results of this study that needs to be communicated to the public, it will be done through the mass media.Background Since the outbreak of the novel coronavirus disease from Wuhan, China, in early December 2019, many scientists focused on this infection to find a way to deal with it. Due to the dramatic scientific growth in this field, we conducted a scientometric study to gain a better understanding of the scientific literature on COVID-19. Methods We extracted all COVID-19 documents indexed in the Scopus from December 1, 2019, to April 1, 2020, without any language limitation and determined their bibliometric characteristics, including document type, open accessibility status, citation counting, H-index, top cited documents, the most productive countries, institutions and journals, international collaboration, the most frequent terms and keywords, journal bibliographic coupling and cocitations. https://www.selleckchem.com/products/ziprasidone.html Results A total of 923 documents on COVID-19 were retrieved, of which 418 were original articles. All documents had received 2551 citations with an average citation of 2.76 per document and an h-index of 23. China ranked first with 348 documents, followed by the United States (n = 160).
