Zeeneldin, A. A., and F. M. Taha, "Qatar biomedical and cancer publications in PubMed between 2000 and 2012.", Qatar medical journal, vol. 2014, issue 1, pp. 31-7, 2014. Abstract

BACKGROUND: The aim of this work was to analyse the past trends of biomedical and cancer publications from Qatar listed on PubMed for the years 2000-2012. These findings were then compared with the corresponding global number of publications.

METHODS: PubMed was searched for cancer publications, clinical trials, publications on humans or other species. Searching for "Qatar*" in the "Affiliation" field yielded the lowest number of publications; searching for "Qatar*" in the "Affiliation" or in "Title/Abstract" yielded a moderate number of results and searching for "Qatar*" in the "Affiliation" or "Title/Abstract" or "Text Word" fields yielded the highest number of publications. The annual percentage change (APC) from one year to the next was calculated for the population and each type of publication. Information on the population of Qatar was gathered from the website of Qatar Statistics Authority to determine the correlation of papers published per 1000 population.

RESULTS: The number of publications retrieved from PubMed was not particularly different for each variation of search carried out. However, the most representative number of publications was retrieved upon searching for "Qatar*" in the "Affiliation" or in "Title/Abstract" fields. Between the years 2000 and 2012, the total number of biomedical publications from Qatar increased 24 times with an average APC of 33.4%, which was found to be more than the APC of the population in Qatar which averaged at 9%. The number of biomedical publications per 1000 population increased from 0.02 in 2000 to 0.15% in 2012. Most publications retrieved were humans studies and occasionally were for other animal species. Cancer publications in Qatar represented 16.9% of the total publications and the number of cancer publications per 1000 population increased from 0% in 2000 to 0.02% in 2012. Publications classified as clinical trials represented 4.6% of Qatar biomedical publications. Publication of cancer clinical trials were very rare (0.4%).

CONCLUSIONS: Despite the obvious increase in Qatar biomedical and cancer publications in PubMed, the absolute numbers were relatively small. While strategies are in place, leaders of Qatar biomedical research need to consider increasing cancer research and clinical trials to meet the country's needs. Linking research output to researchers, research facilities and research funding is needed.

Virginity is the nullity of sexual experience in females. However, the use of virginity testing as proof of previous involvement in sexual relations is dependent on having an intact hymen, which refers to a hymen with no signs of previous penetrating injury. Although the quality of this evidence in questioned virginity is extremely poor and considered a violation of human rights, it still constitutes a major facet in medicolegal investigations of sexual assaults. This work evaluates virginity testing as currently practiced in many countries, including Egypt, in terms of medical and legal considerations.

Agricultural water appropriation has undergone rapid changes in recent decades, but estimates of global water appropriation have not been updated with the latest data and consistent methods. Documenting these changes is challenging given the heterogeneous water use landscape and the growing influence of human activities worldwide, and this complexity cannot be well addressed with the existing methodology, which is subject to large model uncertainties. Here, a spatial analysis and aggregated method was proposed to quantify and refine estimates of global agricultural water appropriation (GAWA) in terms of consumptive freshwater use, with data derived from Earth observations, independent of estimates from hydrological models. The results show the global water appropriation at the pixel scale, in agroecological zones and in the main water-consuming countries, including global maps of rainfed and irrigated cropland evapotranspiration (ET), net water consumption due to irrigation, natural ET and renewable freshwater resources (RFWR), and indicate that agriculture remains the largest user in terms of both water consumption and withdrawals worldwide, representing 87% of global water consumption, with approximately 60% of global freshwater withdrawals devoted to irrigation circa 2015. The percentage of withdrawals devoted to irrigation has decreased in recent decades when compared to the previous estimate of 70%. The results reveal the actual global crop consumptive use (8053.6 km3/yr) of blue and green water and the total human water consumption (8442 km3/yr), which represents the part of the water cycle affected by human intervention, mainly (95.4%) by agriculture. This study reveals that high-resolution irrigated croplands are essential for accurate estimations of water use appropriation and demonstrates that earth observation-derived data can provide a new understanding of global water use landscape. The study can support decision making in sustaining food and water security, and implementing water-adapted sustainable agricultural policies.
