Predictors of the publication of the doctoral thesis at the Faculty of Medicine of Sousse (Tunisia).

AIM: To identify the predictive factors for the publication of theses defended at the Faculty of Medicine of Sousse (FMSO) in Tunisia. METHODS: The development of the dissertation was studied following the interrogation of three databases "Medline", "Scopus" and "article @INIST" as well as "Scholar Google". The drafting quality of the thesis summary was assessed using a grid of 20 iso-weighted items. The predictors of publication were studied by binary logistic regression, with a significance level of 10%. RESULTS: Out of the 670 theses defended at the FMSO, the mention "proposal for the thesis prize" was awarded for 22% of the thesis students. These theses were of the "clinical" type in 68% of cases, 80% of which were in "case study" format. The writing quality was deemed satisfactory in 47% of the theses. The publication rate was only 10.3%. The univariate analysis found three factors determining the publication of theses: the field of non-clinical research: epidemiological or fundamental, good editorial quality and the mention "proposal for the thesis prize". After adjustment, the latter was the only independent predictor of the publication of the thesis (ORa=1.60[1.007-2.559]). CONCLUSION: This low rate of publication of theses at the FMSO illustrates the difficulties of thesis students and their directors in research methodology and scientific writing. Theses accepted with distinction must be better accompanied to facilitate their publication.

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.

Epidemiology of metabolic syndrome in Tunisia. HSHS 5 study.

OBJECTIVE: To measure the prevalence of metabolic syndrome and its components in the HSHS cohort (Hammam Sousse, Tunisia), in 2009, and to identify its determining factors. METHODS: This was a descriptive epidemiological study of the "community based" type having focused on a random sample of people aged 20 and over. The metabolic syndrome was defined according to the criteria of the "International Diabetes Federation" (IDF 2005) and those of the "National Cholesterol Education Program-Adult Treatment Panel III" (NCEP-ATP III, 2001). RESULTS: The study involved 1441 people including 960 women (66.6%). The age- and sex-adjusted prevalences of increased waist circumference, blood pressure, blood sugar and triglycerides, and decreased HDL-cholesterol were respectively 63.2%, 95%CI[62.5-63.8]; 47.7%, 95%CI[47.4-48.6]; 25.7%, 95%CI[25.1-26.2]; 11.9%, 95%CI[11.4-12.3] and 65,6%, 95%CI[65.0-66.2], according to IDF thresholds and 37.4%, 95%CI[36.3-37.6]; 45.7%, 95%CI[45.4-46.6]; 13.8%, 95%CI[13.4-14.2]; 8.4%, 95%CI[8.0-8.7] and 61.9%, 95%CI[61.2-62.5], according to those of the NCEP-ATP III. The prevalence of metabolic syndrome adjusted for age and sex was 36.5% 95%CI[33.0%-38.9%] according to the IDF definition and 23.0% 95%CI[20.4%-25.6%] according to that of NCEP-ATP III. The multivariate study by logistic regression made it possible to retain three significant independent determining factors of the metabolic syndrome: age ≥40 years, low level of physical activity and family history of diabetes mellitus with respectively adjusted ORs of 3.77 95%CI[2.70-5.27], 1.39 95%CI[1.01-1.89], 1.62 95%CI[1.21-2.15], according to IDF and 5.87 95%CI[3.88 -8.88], 1.47 95%CI[1.07-2.01] and 1.45 95%CI[1.07-1.96], according to NCEP-ATP III . CONCLUSION: With this high prevalence rate of the metabolic syndrome, the establishment of an action plan would be essential. This plan should be based on the combination of the promotion of physical activity and screening for the components of the metabolic syndrome, particularly in subjects aged 40 or over, with a family history of diabetes mellitus.

Epidemiology of obesity in Tunisia: HSHS4 study (Hammam Sousse Sahloul Heart Study).

INTRODUCTION: The HSHS study is a community-based survey focused on cardiovascular risk factors. AIM: The objectives of this specific analysis were to determine the prevalence of obesity and overweight in the general population of Hammam Sousse (Tunisia) and to identify their predisposing factors. METHODS: HSHS was conducted with a random sample of households, composed by the EPI (Expanded Program on Immunization) technique. All people aged 20 and over, met on the day of the survey, at their homes, were included. Obesity, overweight and weight overload were defined with reference to Body Mass Index (BMI): Obesity (BMI≥30 kg/m²), Overweight (25≤BMI (25≤BMI <30 kg/m²), weight overload (BMI≥25 kg/m²). Physical activity was evaluated according to the level of energy equivalents (Metabolic Equivalent Task) or MET, this level was considered low below 600 MET min/week. The calculated prevalences were accompanied by their 95%CI (Confidence Intervals). The multivariate study was conducted by logistic regression, measuring the adjusted Odds Ratio (ORa) Results: The study population was composed of 481 men and 960 women, (sex-ratio=0.50). The age ranged from 20 to 96 years with an average of 49.6±16444 years in men and 46.6±16.2 in women (p <0.05). After adjusting for age and sex, the prevalence rates of overweight, obesity, and weight overload were respectively 36.18%, 95%CI [35.38%-36.62%], 28.11%; 95%CI [27.42%-28.58%] and 64.28%; 95%CI [63.38%-64.62%]. Obesity was determined, in addition to female sex, age 40 or over and low level of education, by low level of physical activity (ORa=1.56; 95%CI [1.21-2.03], p<10-2). CONCLUSION: In adults, the prevalence of obesity and overweight were high and determined by insufficient physical activity. The results of this study, which can be extrapolated to other Tunisian cities, should motivate the general population to establish a heart health promotion plan, in partnership with civil society.

[Epidemiology of smoking in the male population in Tunisia. HSHS Study 6].

OBJECTIVES: To determine the prevalence of smoking in the male population of Hammam Sousse (Tunisia), to describe its modalities and to analyse its determining factors. METHODS: This was a "community-based" study, carried out on a random sample of households, including a population of males aged 20 or over. The data were collected, at home, using a specific support consisting of a lifestyle questionnaire, a physical examination, and a biological assessment, oriented towards cardiovascular risk factors. Smoking behaviour covered both forms of cigarettes and Narghile. "Current smokers" included all men declaring that they smoked at the time of the survey, including "regular smokers", who smoked daily at the time of the survey, and "occasional smokers", less than once a day. The group of "non-smokers" at the time of the survey was the sum of "ex-smokers" and those "who had never smoked". The prevalences were calculated after their weighting according to age and the adjusted odds ratios were measured following a multivariate study by logistic regression. RESULTS: The study population was composed of 481 men with an average age of 49.6±16.35 years and a median of 49 years. Mean body mass index and systolic blood pressure were 26.9 kg/m2 ±4.20 and 151.9 mmHg±24.36, respectively. After adjusting for age, the proportions of current users, former users and subjects who had never used tobacco (all forms combined) were respectively 50.4% (95% CI [49.49-51.3]), 17.4% (95% CI [16.71-18.08]) and 30.9% (95% CI [30.06-31.73]). Daily cigarette consumption was characterized by an average onset at age 20.1±6.91 years, an average duration of 27.0±15.22 years and an average amount of 17.6±9.8 cigarettes smoked per day. After adjusting for age, level of education, and socioeconomic level, smoking behaviour was attributed to a single independent risk factor: the presence of a smoker in the family, with an adjusted OR of 45.17 (p (p<10-3) for regular cigarette smokers, and 29.66 for regular tobacco users of all forms. CONCLUSION: Smoking would be a real endemic in Tunisia, threatening the cardiovascular health of the country. The national health system is called upon to strengthen its action plan for the prevention and control of smoking, in all living environments: family, school, work, health centre, etc.

Editorial quality of the doctoral thesis at the Faculty of Medicine of Sousse (Tunisia).

OBJECTIVE: To assess the writing quality of the theses defended at the Faculty of Medicine of Sousse (FMSo). METHODS: This is a bibliometric, transversal and exhaustive study done on all theses defended at the FMSo between 2001 and 2005. The writing quality of the thesis was assessed, via double reading, by a grid applied to its abstract. This grid was composed of 20 items detailing the principles of scientific writing. A thesis was considered "satisfactory" when the writing score was ≥15 / 20. RESULTS: During this five-year period, 670 theses was defended at the FMSo (an average of 134 theses per year), which in 93% of cases were research ones. All these theses were written in French except for one. On a 20-point scale, the average thesis editorial score was 14.1 ± 2.2. The writing quality was judged satisfactory in 47% of the theses. The objective of the thesis, research design and study population were mentioned, respectively, in 81%, 77% and 91% of theses abstracts. However, the descriptors chosen were MeSH words in only 42% of the time; Data sources and standard deviation were mentioned in only 25% and 9.6% of the abstracts, respectively. CONCLUSION: The writing quality of the thesis at the FMSo suffered mainly from documentary, methodological and statistical insufficiencies. The introduction of a scientific medical writing module in the curriculum of the FMSo would be essential for the optimization of the medical thesis.

Epidemiology of dyslipidemia in Tunisia, HSHS 3 study (Hammam Sousse Sahloul Heart Study).

INTRODUCTION: Dyslipidemia is a major cause of morbidity and mortality worldwide because it increases the risk of cardiovascular diseases. AIM: To determine the prevalence of dyslipidemia and its components in the general population of Hammam Sousse (Tunisia) and to identify its risk factors. METHODS: This was an analysis of the HSHS database (Hammam Sousse Sahloul Heart Study), a «community-based¼ cross-sectional study on cardiovascular risk factors including dyslipidemia, with a random sample in two-stages, proportional-probability clusters. All subjects above 20 years underwent a lifestyle interview, clinical examination with anthropometric measurements, and blood sampling. Dyslipidemia was defined by: total cholesterol ≥5.2 mmol/l, hyper LDL (Low Density Lipoprotein) cholesterolemia ≥4.1 mmol/l, hypo HDL (High Density Lipoprotein) cholesterolemia <1.03 mmol/l for men and <1.29 mmol/l for women and hyper-triglyceridaemia: ≥2.26 mmol/l. Multivariate logistic regression analysis was conducted to determine factors independently associated with dyslipidemia. RESULTS: The study population was composed of 481 males (M) and 960 females (F), with a sex ratio of 0.5. Mean cholesterol was higher in women (5 mmol/l±1.01) than in men (4.8 mmol/l±0.92). Only 24.9% of men and 29.1% of women had normal HDL cholesterol levels. Women had higher levels of hypercholesterolemia and LDL cholesterolemia than men (p<10-6). Multivariate analysis showed that dyslipidemia was independently and statistically significantly associated with age ≥40 years (p<10-3), physical inactivity (p<10-3) and obesity (p=0.025). CONCLUSION: As a result of the epidemiological situation of dyslipidemia, the promotion of an active lifestyle seems essential. In addition, nutritional education improves the lipid profile by promoting weight loss and balancing lipid consumption.

Epidemiology of diabetes mellitus in Tunisia. HSHS 2 study (Hammam Sousse Sahloul Heart Study).

BACKGROUND: National epidemiological studies on diabetes mellitus are rare, ancient and often carried out schools or clinics settings. OBJECTIVES: To determine the prevalence of diabetes mellitus and identify its risk factors in the adult population of the city of Hammam Sousse (Tunisia) during the year 2009. METHODS: This study is a part of analysis of the HSHS database (Hammam Sousse Sahloul Heart Study), a «community-based¼ cross-sectional study on cardiovascular risk factors including diabetes mellitus, with a two-stage proportional probability cluster random sample. All subjects aged 20 years and more underwent a lifestyle interview, clinical examination with anthropometric measurements, and blood sampling. The diagnosis of diabetes mellitus was defined by a fasting blood glucose level ≥7 mmol/l. Overweight was defined by a Body Mass Index (BMI) ≥ 25 kg/m². A multivariate logistic regression analysis was conducted to determine independent risk factors associated with diabetes mellitus. RESULTS: The population was composed of 481 males (M) and 960 females (F), a sex ratio of 0.5 with mean ages respectively of 49.6±16.35 years and 46.6±16.18 years. The prevalence of diabetes mellitus adjusted by age and sex was 12.1% (95%CI[11.7-12.5]); M: 12.7% (95%CI[12.1-13.3]), F: 11.5% (95%CI[10.9-12.1]). The prevalence rate of patients newly detected with diabetes mellitus was 1.9% (95%CI[1.7-2.1]): M: 1.8% (95%CI[1.6-2.0]), F: 2.1% (95%CI[1.8-2.4]). The multivariate study revealed five independent factors significantly associated with diabetes mellitus. In addition to non-modifiable factors (male gender, age ≥40 years old, low schooling level and family history of diabetes), diabetes mellitus was 2 (95%CI[1.3-3.2]) times more prevalent in overweight cases. CONCLUSION: In deep trouble of this epidemiological situation of diabetes mellitus, it is urgent to launch a universal intervention strategy based on the promotion of a healthy lifestyle motivating regular physical activity and a low-calorie diet.

Epidemiology of arterial hypertension in Tunisia: Hammam Sousse Sahloul Heart Study (HSHS).

INTRODUCTION: Tunisia is experiencing a double burden of morbidity, characterized by the explosion of cardiovascular diseases and their risk factors including arterial Hypertension. The objective of this study, based on the HSHS cohort (Hammam Sousse Sahloul Heart Study), was to determine the prevalence of hypertension in the general population and to identify its predisposing factors. METHODS: HSHS is a cardiovascular health promotion initiative in the city of Hammam Sousse (Tunisia). The study was conducted via a random sample of households, using the WHO PEV technique, made up of 33 clusters, of 33 households each. All people aged 20 and over, included, benefited from a questionnaire, a physical examination and a biological assessment. The Systolic Blood Pressure (SBP) and the Diastolic Blood Pressure (DBP) were measured from the average of the last two measurements, by an OMRON type tensiometer, of suitable width. These prevalences were adjusted according to sex and age group, by their weighting coefficients in the general population, and they were accompanied by their 95% CIs. Binary logistic regression was conducted to identify independent factors associated with hypertension. RESULTS: The study population was composed of 481 men (33.4%) and 960 women (66.6%), with an average age of 49.6±16.35 years in males (M) and 46.6±16.18 in females (F). In addition to the family history of hypertension, the sufficient weekly consumption of vegetables and fruits was low (M: 32.4%, F: 24.9%). The adjusted rate of hypertension in the adult study population was 32.5%, 95%CI[31.9-33.1] (M: 36.4%, 95%CI[35, 5-37.3]; F: 28.4%; 95% CI[27.6-29.2]), reaching in the age group of 60 years and above: M: 74.6% (95%CI[66.9-82.3], F: 82.7% (95%CI[73.8-83.6]) Multivariate analysis identified five independent factors significantly associated with hypertension: male sex (ORa=1.55 [1.18-2.03]), age over 40 years (ORa=6.54[4.70-9.11]), low level of schooling (ORa=1.80 [1.36-2.38]), low physical activity (ORa=1.42[1.07-1.88]) and high socio-economic level (ORa=1 .84 [1.30-2.63]). CONCLUSION: The HSHS study confirmed the high prevalence of hypertension, and the extent of its low detection and control. Hence the need for a universal approach to health promotion, oriented towards the general population, piloted by its local organizations, based on the adoption of a healthy lifestyle, and centered on physical activity.

Epidemiology of elderly dependency in Tunisia. HSHS study 7.

AIM: Measure the functional autonomy of elderly people and identify its components and determinants in the HSHS (Hammam-Sousse Sahloul Heart Study) population (phase 2009, Tunisia). METHODS: This study was concerned with the quality of life of elderly people aged 65 years or more, living at home from the HSHS cohort divided into two groups: young-old (65-74 years old) and old-old (≥75 years old). The autonomy was assessed using the "Activities of Daily Living" (ADL) scale ranging from 0 to 6, the "Instrumental Activities of Daily Living" (IADL) scale ranging from 0 to 8 and, the combined scale ranging from zero to 14, iso-weighted at one point per activity. Autonomy in daily activities was retained for an ADL score=6, and an IADL score (F=8; H=5). Subjects with an overall score (sum of ADL and IADL) of 10-14 points were considered globally autonomous. RESULTS: The population study was predominantly female (sex-ratio=0,6) with an important proportion of old-old (M=43%, F=37%). Autonomy rates were by ADL (M=57.4%, F=36.1%, p < 10-2), IADL (M=16%, F=23.9%), and by combined score (M=60.6%, F=69%, p=NS). The typology of dependency was dominated by transferring (M=35%, F=61%) and bathing (M=14%, F=19%) for ADL activities, and shopping (M=36%, F=49%) and the use of means of transport (M=22%, F=43%) for IADL activities. After adjustment, autonomy in daily activities was attributed to two independent factors: male sex (ORa=3.98, CI95% [1.328-11.971]) and age group 65-75 (ORa=4.04, CI95% [2.039- 8.025]). Autonomy in instrumental activities was associated with age group (ORa=31.5, CI95% [4.087-233.514]). Finally, overall autonomy (current and instrumental) was associated independently after logistic regression, with four independent factors, two of which were not modifiable: being female (ORa=3.1, CI95% [1.2-8.1]) and 65 to 75 years (ORa=6.2, CI95% [3.1-12.3]) and two modifiable factors: no recent hospitalization (ORa=3.8, CI95% [1.4-10.4]) and a sufficient level of physical activity (ORa=2.6, CI95% [1.3-5.3]). CONCLUSION: The physical dependency rate of the elderly is very high in Tunisia. The promotion of physical activity, the extension of similar studies and the development of could improve the support of these people.

Global university performance. Bibliometric analysis of the ARWU platform (2003-2020).

OBJECTIVES: Describe the 2020 report of the ARWU "Academic Ranking World Universities" classification and identify, accordingly, the roadmap of academic excellence, particularly in the countries of the Greater Maghreb. METHODS: This is an in-depth reading of the 2020 results of the ARWU bibliometric platform (launched in 2003) from top 1000 world-class universities. Six criteria were used in this ranking: 1. Alumni (10%): students who received Nobel / Fields prizes; 2. Award (15%): professors who have won the Nobel / Fields prizes; 3. HiCi (20%): Most cited scientists; 4. PUB (20%): number of publications 5. TOP (20%): proportion of publications in the most influential periodicals; 6. PCP (10%): Per Capita Performance. RESULTS: The 2020 ARWU ranking was characterized by the domination of the "Top 10" ranking by the United States, particularly the "Harvard University", the Asian boom of 55% of the "Top 1000" ranking (Chinese universities evolved from 16 in 2004 to 81 in 2020 in the "Top 500" list) and finally an African incubation of academic excellence, manifested by the selection of nine South African institutions (including the "University of Cape Town ", world rank between 201-300), and the re-entry for the first time of a Maghreb university in the" Top 1000 "list, Tunis El Manar (rank between 901-1000), with the following scores: N&S: 1 , 4; Pub: 26.1 and PCP: 10.3, for a total score of 37.8 points. CONCLUSION: This report proves once again, the promising academic perspectives of Asia and Africa in the inclusion of the "Top 1000" list of the ARWU ranking. The roadmap for academic excellence would thus be based on the triad of centering scientific publications, in prestigious journals and by national author networks.

Bibliometric profile of the doctoral thesis at the Faculty of Medicine of Sousse (Tunisia).

OBJECTIVE: Describe the bibliometric profile of medical dissertations in Sousse Faculty of Medicine (SOFM) in Tunisia. METHODS: This is a cross-sectional bibliometric study of all dissertations defended from 2001 to 2005. The data were collected through a reading grid applied to the cover page, conclusion, and summary of the thesis. The specialty of the dissertation has been attributed to its first director. Themes were defined by the "essential descriptor", chosen from the descriptors used for the indexing. RESULTS: The 670 theses collected, all written in French except one in Arabic, were original, pedagogic or bibliographical works in respectively 93.3%, 6.4%, and 0.3% respectively. "Community and Preventive Medicine" was the discipline that generated the most theses with a proportion of 8.9%. About half (48%) of the dissertations were supervised by two directors. The first director was a University Hospital Professor or an Associate Professor of Conferences, respectively in 34% and 42% of cases. The chairman of the thesis jury belonged to the same specialty as the first director and was from the same department in respectively 54% and 41% of cases. Four "essential descriptors" were frequently cited as indexation of the dissertation: "tumor", "CD-Rom", "trauma", and "diabetes". These dissertations were "clinical" type in 68% of cases, of which around 80% were "case studies". CONCLUSION: The doctoral dissertation in SOFM was characterized by the orientation towards clinical and epidemiological research and the preference for general medicine and community health themes. It's often recourse to a basic research estimate and its writing in French would be two factors limiting its scientific promotion and its social influence.
