Background This study aimed to assess the impact of 15 days before, 15 days during, and 15 days after the lockdown on the trends in the prevalence and mortality in 27 countries during COVID-19 pandemic. Methods Twenty-seven countries were randomly selected from the different continents. The information on the trends in the prevalence and mortality due to COVID-19 pandemic in 27 countries was obtained from World Health Organization and lockdown data were obtained from concerned countries and their ministries. The impact of lockdown for 15 days before, 15 days during, and 15 days after the lockdown on the prevalence and mortality due to the COVID-19 pandemic in 27 countries was analyzed. Results The findings showed that 15 days after the lockdown there was a trend toward a decline, but no significant decline in the mean prevalence and mean mortality rate due to the COVID-19 pandemic compared to 15 days before, and 15 days during the lockdown in 27 countries. The mean growth factor for number of cases was 1.18 and for mortality rate was 1.16. Conclusions The findings indicate that 15 days after the lockdown, daily cases of COVID-19 and the growth factor of the disease showed a declined trend, but there was no significant decline in the prevalence and mortality.

ObjectivesThis study aimed to compare the impact of Gross Domestic Product (GDP) per capita, spending on Research and Development (R&D), number of universities, and Indexed Scientific Journals on total number of research documents (papers), citations per document and Hirsch index (H-index) in various science and social science subjects among Asian countries.Materials and MethodsIn this study, 40 Asian countries were included. The information regarding Asian countries, their GDP per capita, spending on R&D, total number of universities and indexed scientific journals were collected. We recorded the bibliometric indicators, including total number of research documents, citations per document and H-index in various science and social sciences subjects during the period 1996–2011. The main sources for information were World Bank, SCI-mago/Scopus and Web of Science; Thomson Reuters.ResultsThe mean per capita GDP for all the Asian countries is 14448.31±2854.40 US$, yearly per capita spending on R&D 0.64±0.16 US$, number of universities 72.37±18.32 and mean number of ISI indexed journal per country is 17.97±7.35. The mean of research documents published in various science and social science subjects among all the Asian countries during the period 1996–2011 is 158086.92±69204.09; citations per document 8.67±0.48; and H-index 122.8±19.21. Spending on R&D, number of universities and indexed journals have a positive correlation with number of published documents, citations per document and H-index in various science and social science subjects. However, there was no association between the per capita GDP and research outcomes.ConclusionThe Asian countries who spend more on R&D have a large number of universities and scientific indexed journals produced more in research outcomes including total number of research publication, citations per documents and H-index in various science and social science subjects.

The novel coronavirus infection outbreak has posed a major threat to international health system and economy. This study is aimed at investigating the biological and epidemiological trends in the prevalence and mortality due to outbreaks of novel coronavirus (COVID-19) infections.

The rising prevalence of diabetes mellitus (DM) is a serious global health concern. The world is experiencing type 2 diabetes epidemics and prevalence differs by gender, regions, and level of socioeconomic development. Type 2 diabetes mellitus (T2DM) in men increased at a faster rate and numbers are continuing to rise in some regions of the world. This study aimed to estimate the prevalence of T2DM among men in the Middle East countries. Seventy-four research articles were identified through search engines including Web of Science, Medline, PubMed, EMBASE, Scopus, and Ovid databases by using keywords “epidemiology,” “prevalence,” “diabetes mellitus,” and individual names of the Middle East states. Finally, 17 studies were included for the assessment of prevalence of T2DM among men in the Middle East. In the Middle East, high prevalence of T2DM among men was identified in Bahrain (33.60%), Saudi Arabia (29.10%), United Arab Emirates (UAE; 25.83%), and Kuwait (25.40%), whereas low prevalence was reported in Iran (9.90%) and Yemen (9.80%). The random pooled prevalence in the Gulf Cooperation Council (GCC) states was (24.0%) compared to non-GCC states (16.0%), and in both GCC and non-GCC countries combined, it was 19%. The prevalence was significantly associated with the gross domestic product of these states ( p = .0005). Despite different socioeconomic and cultural settings in the Middle East, the rising T2DM prevalence among men was identified in Bahrain, Saudi Arabia, UAE, and Kuwait. These states must incorporate future diabetes defensive strategies targeting the Middle East population to minimize the burden of DM from the region.

Objectives: This study aimed to assess the impact of the Gross Domestic Product (GDP), spending on Research and Development (R&D), the number of universities and scientific journals on the published research documents, citable documents, citations per document and H-index in environmental sciences in the Middle East countries. Materials and Methods: All the 16 Middle East countries were included in the study. Information regarding the GDP, spending on R&D, the total number of universities and indexed journals was collected. Total number of research documents (papers), citable documents,
