Who are the Best Scientists in Tunisia? Analysis of the 2023 edition of the "Research.com" platform.

AIM: Describe the performance of scientists assigned to Tunisian research structures, according to their academic disciplines, according to the Research.com platform https://research.com/), in 2023. METHODS: This is a reading focused on the productivity of scientists working in Tunisia, of the new 2023 edition of the international Research.com platform, ensuring the monitoring of 26 academic disciplines and 166880 scientists, affiliated with around three thousand research structures, and representing 1% of leading scientists in a discipline. In this platform, the ranking of researchers was based on the D-index indicator (equivalent to the h-index of a given discipline), calculated as of December 21, 2022. RESULTS: Around fifteen of the "Best Scientists", affiliated with Tunisian research structures, were selected by the Research.com platform (2023), belonging to eight disciplines including particularly "Chemistry", "Plant Sciences and Agronomy" and "Engineering and Technology". These researchers were attached to seven establishments including the universities of "Sfax" and "Monastir" and the "Borj Cedria - Sidi Thabet Biotechnology Center". Among these winners: Professors Moncef NASRI (Sfax, "Biology and Biochemistry", D-index=74), Chedly ABDELLY (Borj Cedria, "Agronomy", D-index=72) and Adel M. ALIMI (Sfax, "computer science¼, D-index=44). CONCLUSION: In Tunisia, the list of "Best scientists" in the Research.com ranking (2023) made it possible to identify two colleges of leaders in scientific research ("Health Sciences" and "Fundamental Sciences"), constituting priority consortia for strengthening the national strategy to support the mobility and networking of researchers, as well as the proliferation and visibility of their publications.

Epidemio-clinical profile of Takayasu Arteritis at the Center of Tunisia.

INTRODUCTION: Takayasu's Arteritis (TA) is a systemic vasculitis affecting the aorta and its main branches. AIM: To describe the epidemiological, diagnostic, therapeutic and prognostic profile of TA in the referral departments of internal medicine in the Sousse region (Tunisia). METHODS: This is a descriptive, retrospective and exhaustive study, carried out in the two departments of Internal Medicine of Sousse. Patients followed for AT, from 1996 to 2020 were included. The disease was defined according to the classification criteria of the American College of Rheumatology. Disease activity was assessed according to NIH criteria. Age referred to the date of diagnosis. RESULTS: The study population consisted of 40 patients (Sahloul: n=32, Hached: n=8) with a sex ratio=0.17 and a median age=35 years (IIQ=[30-41]). The median diagnostic delay was 5 months (IIQ=[2-14]). The main clinical sign was pulse abolition and/or decrease (78%). Aortic stenosis was the main arterial lesion found (98%). Treatment was based on corticosteroids (95%) and immunosuppressants (42%). The prognosis of TA was often active (62%), with vascular co-morbidity (60%) and iatrogenic complications (35%). CONCLUSION: The epidemiological-clinical profile of AT in the region of Sousse (Tunisia) was characterized by a female predominance, a diagnostic delay, a clinical polymorphism, and evolution towards vascular co-morbidities.

Results of 25 years of Maghrebian scientific medical research in the Grand Maghreb. Bibliometric analysis of the Scimago platform (1996-2020).

OBJECTIVE: Describe the trend and the characteristics of the positioning of Maghreb medical production and its visibility, at the global, African and Arab level, following an in-depth reading of the Scimago platform, over a period of 25 years (1996-2020 ). METHODS: This is an in-depth reading, centered on the Maghreb, of the Maghreb medical production referenced on the Scimago platform, from 1996 to 2020. The bibliometric extracts were based on the number of published "documents" and the index H: number of articles (h) from a country having received at least h citations. The benchmarking of the productivity and medical visibility of the five Maghreb countries (Tunisia, Morocco, Algeria, Libya, Mauritania) was carried out at the global (237 countries), African (59 countries) and Arab (21 countries) level. RESULTS: Following the first African countries producing the most medical documents (South Africa, Egypt and Nigeria), the position of the Maghreb countries varied from 4 in Tunisia to 36 in Mauritania. In Arab countries, the position of medical production, dominated by Egypt and Saudi Arabia, was 12 and 18, successively in Algeria and Libya. The evolution of medical documents recorded a cross between Tunisia and Morocco in 2014, followed by a deceleration in Moroccan production. In the Maghreb, the h index varied from 154 in Tunisia to 29 in Mauritania. CONCLUSION: In addition to its weak position in the world, African and Arab rankings over the past 25 years, Maghreb medical research has been characterized by a major fluctuation. The "Alliance for Excellence" charter of the PRP2S Network, based on the promotion of university essays and electronic journals, constitutes an operational roadmap for the development of the production and visibility of research in the Maghreb.
