Introduction The Gulf Cooperation Council (GCC or 'Arabian Gulf'), comprising Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and United Arab Emirates, is a political organization sharing a common history and culture. All GCC nations have made substantial investments in telecommunications and electronic health infrastructure since 2000. Methods We conducted a literature search in English and Arabic on peer-reviewed e-health research up to December 2014 originating in the GCC. The objective was to retrieve all research on e-health in the GCC and to categorize and analyse it qualitatively to reveal the current state of e-health research and development in the region. Inclusion criteria included peer-reviewed articles, books, book chapters, conference papers and graduate theses written on e-health in the GCC. Blogs, health websites and non-peer-reviewed literature were excluded. Results Three hundred and six articles were retrieved, categorized and analysed qualitatively to reveal the state of e-health research in the GCC. Both country-specific and GCC-wide major themes were identified using NVivo 10.0 qualitative software and summarized. The most common type of study was an overview (35.0%), with common study designs of case studies (26.8%) and descriptive articles (46.4%). Significant themes were: prospective national benefits from e-health, implementation and satisfaction with electronic health records, online technologies in medical education, innovative systems (case studies), and information security and personal health information. Discussion This is the first comprehensive analytical literature review of e-health in the GCC. Important research gaps were identified: few cost-benefit analyses, controlled interventional studies, or research targeting gender and religious issues were retrieved.
Angiosarcomas are highly aggressive tumors of endothelial origin, which carry a poor prognosis. Fenofibrate is a hypolipidemic drug, which acts by activating the transcription factor PPARα. It has also been widely reported to have ‘anti-cancer’ activity. The current study investigated its effect in a murine VEGF-dependent angiosarcoma cell-line, MS1 VEGF. The study utilised assays to monitor cell proliferation and viability, apoptosis, cell cycle progression, mitochondrial membrane potential, changes in protein expression, and changes in miRNA expression using microarrays. Fenofibrate showed potent anti-proliferative action in MS1 VEGF angiosarcoma cells, without inducing apoptosis. It enriched cells in G2/M cell cycle phase and hyperpolarised mitochondria. Other PPARα activators failed to mimic fenofibrate action. Inhibitors of PPARα and NFκB failed to reverse the inhibitory effect of fenofibrate and their combination with fenofibrate was cytotoxic. Fenofibrate downregulated the expression of key VEGF-effector proteins, including Akt, ERK, Bcl-2 and survivin, and a chemical inhibitor screen discovered relevance of these proteins to cell proliferation. A miRNA microarray revealed that fenofibrate differentially regulated cellular miRNAs with known roles in cancer and angiogenesis. The data raise the possibility that fenofibrate could be useful in angiosarcoma therapy, especially considering its well-established clinical safety and tolerability profile.
Objective: This study aimed to determine the effect of reperfusion therapies on the occurrence of early post-stroke seizures (PSS) in patients with acute ischemic stroke (AIS).Background: Reperfusion therapies are paramount to the treatment of stroke in the acute phase. However, their effect on the incidence of early seizures after an AIS remains unclear.Design and Methods: The stroke database at Hamad Medical Corporation was used to identify all patients who received reperfusion therapies for AIS from 2016 to 2019. They were matched with patients of similar diagnosis, gender, age, and stroke severity as measured by National Institutes of Health Stroke Scale (NIHSS) who did not receive such treatment. The rates of early PSS were calculated for each group.Results: The results showed that 508 patients received reperfusion therapies (342 had IV thrombolysis only, 70 had thrombectomies only, and 96 had received both), compared with 501 matched patients receiving standard stroke unit care. Patients who received reperfusion therapies were similar to their matched controls for mean admission NIHSS score (9.87 vs. 9.79; p = 0.831), mean age (53.3 vs. 53.2 years; p = 0.849), and gender distribution (85 vs. 86% men; p = 0.655). The group receiving reperfusion therapies was found to have increased stroke cortical involvement (62 vs. 49.3%, p < 0.001) and hemorrhagic transformation rates (33.5 vs. 18.6%, p < 0.001) compared with the control group. The rate of early PSS was significantly lower in patients who received reperfusion therapies compared with those who did not (3.1 vs. 5.8%, respectively; p = 0.042). When we excluded seizures occurring at stroke onset prior to any potential treatment implementation, the difference in early PSS rates between the two groups was no longer significant (2.6 vs. 3.9%, respectively; p = 0.251). There was no significant difference in early PSS rate based on the type of reperfusion therapy either (3.2% with thrombolysis, 2.9% with thrombectomy, and 3.1% for the combined treatment, p = 0.309).Conclusions: Treatment of AIS with either thrombectomy, thrombolysis, or both does not increase the risk of early PSS.
Highlights In the evaluation of a first seizure, the capture of epileptiform discharges is increased with 24-hour EEG recordings. This likely stems from a combination of increased sampling and robust sleep recording. Subtle seizures were also recorded by prolonging the EEG in a minority of first seizure presentations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
