Epidemiologic features and management of hypertension in Tunisia, the results from the Hypertension National Registry (NaTuRe HTN).

BACKGROUND: Hypertension is the leading cause of morbi-mortality in our country. Thus, we conducted this national survey on hypertension to analyze the profile of the Tunisian hypertensive patient and to assess the level of blood pressure control. METHODS: Nature HTN is an observational multicentric survey, including hypertensive individuals and consulting their doctors during the period of the study. Blood pressure measurements were conducted during consultation, using a standardized auscultatory or oscillometric sphygmomanometer after at least 15 min of rest. The diagnosis of new hypertension is based on the 2018 ESC/ESH criteria. The primary endpoint of our study was uncontrolled hypertension defined by a systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg. RESULTS: Three hundred twenty-one investigators participated in the study. We enrolled 25,890 patients with a female predominance (Sex ratio, 1.21) and an average age of 64.4 ± 12.2 years. Most individuals were treated in the public sector (74%), 39.4% of patients were diabetic, 25.8% were obese, 44.6% were overweight and 14% were smokers. Hypertension was controlled in 51.7% of cases if we consider 140/90 as a BP target, and only in 18.6% if we consider 130/80 as a target. The independent predictors of uncontrolled blood pressure were male sex (OR = 1.09, 95%CI [1.02-1.16]), age > 65 year-old (OR = 1.07, 95% CI[1.01-1.13], diabetes (OR = 1.18, 95% CI [1.11-1.25], Smoking (OR = 1.15, 95% CI [1.05-1.25]), Obesity (OR = 1.14, 95% CI[1.07-1.21]), management in public sector (OR = 1.25, 95% CI [1.16-1.34]), and Heart rate > 80 bpm (OR = 1.59, 95% CI [1.48-1.71]). Contrarily, high educational level (OR = 0.9, 95% CI [0.84-0.97], absence of history of coronary disease (OR = 0.86, 95% CI [0.8-0.93]), salt restriction (OR = 0.48, 95% CI [0.45-0.51]), drug compliance (OR = 0.57, 95% CI[0.52-0.61]), and regular physical activity (OR = 0.77, 95% CI[0.71-0.84]) are strong predictors of blood pressure control. CONCLUSION: NaTuRe HTN showed that blood pressure control was reached in more than half of the Tunisian people. The control remains low in patients with high cardiovascular profiles and in those treated in the public sector. A national health program based on therapeutic education, regular control and continuous support to the public institutions is needed to decrease the burden of hypertension incidence rate.

An assessment of the air quality in apple warehouses: new records of Aspergillus europaeus, Aspergillus pulverulentus, Penicillium allii and Penicillium sumatraense as decay agents.

Airborne fungi are one of the major components of aeromycobiota known to produce several fungal diseases in fruits. Their presence in indoor environment of warehouses may limit the storage period of apples. Qualitative and quantitative analyses of airborne fungal spores were conducted using gravity settling techniques to detect fungal airspora present in the atmosphere of two apple warehouses in Tunisia. In this study, 375 fungal isolates were obtained and purified. Phylogenetic analysis of calmodulin, beta-tubulin and ITS regions coupled with phenotypic characterization helped to identify 15 fungal species. Penicillium exhibited the highest diversity with ten species detected (Penicillium allii, P. chrysogenum, P. citrinum, P. expansum, P. italicum, P. polonicum, P. solitum, P. steckii, P. sumatraense and P. viridicatum), followed by four species of Aspergillus genus (Aspergillus europaeus, A. flavus, A. niger and A. pulverulentus) and Alternaria alternata. In vivo experiments confirmed the pathogenicity of 13 species at room temperature and under cold-storage conditions. Among them, A. europaeus, A. pulverulentus, P. allii and P. sumatraense were described for the first time as pathogens on apples. The present study identified the major airborne fungi associated with postharvest rot in apple storage facilities in Tunisia and may help in efficient control of postharvest and storage fruit diseases.

[Assessment of the practices and knowledge among cardiologists regarding radiation protection in Tunisia]. / Évaluation des pratiques et connaissances en radioprotection des cardiologues en Tunisie.

INTRODUCTION: interventional cardiology procedures have become complex and expensive in time with a higher risk of exposure to ionizing radiations. The purpose of our study was to assess radiation protection knowledge and practices among Tunisian cardiologists exposed to X-rays. METHODS: we conducted a descriptive, analytical study in October 2019. An anonymous survey on the knowledge and practices regarding radiation protection was sent to all Tunisian cardiologists exposed to X-rays. RESULTS: among 126 cardiologists exposed to X-rays and having received the survey, 58 physicians responded to the survey (48%), with a male predominance (72%, n=42). Thirty-eight physicians (65%) were public sector workers. Average years of working experience were 12.02 years (SD 6.88 years). Half of doctors had a knowledge score of less than 50%. The average practice score was 43.83 (SD 13.95%). Wearing a lead apron, thyroid shield, dosimeter, lead glasses, lead cap accounted for 100% (n=58), 86.2% (n=50), 30.7% (n=18), 12.1% (n=7) and 1.7% (n=1) respectively. There was no correlation between scores and doctor's age as well as the length of working experience. There was no statistical differences between knowledge scores of males and females (p=0.06) or between public sector and private sector (p=0.9). Practice score was significantly higher among men (0.007) and interventional cardiologists compared to rhythmologists and pediatric cardiologists (p<0.001). CONCLUSION: the level of knowledge and practices among Tunisian cardiologists regarding radiation protection is generally insufficient. Then, health authorities should implement regular training programs.
