Prevalence and factors for anxiety and depression among secondary school teachers from Sfax city of Tunisia in times of the coronavirus disease 2019 pandemic: a cross-sectional study.

Introduction: teachers have to adapt during the coronavirus disease 2019 (COVID-19) pandemic to many changes that could potentially make them more vulnerable to psychological distress. We aimed to assess anxiety and depression in Tunisian secondary school teachers during the COVID-19 pandemic and to explore their associated factors. Methods: we conducted a cross-sectional survey concerning Tunisian secondary school teachers between May 1st, 2021, and June 30th, 2021, using an online survey platform via Google Forms. Participants were asked to fill in a form including two psychometric tests: the General Anxiety Disorder 7 (GAD-7) and the Patient Health Questionnaire 9 (PHQ-9). We performed both univariable and multivariable logistic regression analyses. Results: a total of 170 secondary school teachers were included, of whom 22.4% (n=38) were males and 77.6% (n=132) were females. The median age was 45.5 years (Q1=39, Q3=49). The overall anxiety prevalence was 34.7% (n=59) while it was 41.7% (n=71) for depression. In multivariable analysis, anxiety was strongly associated with sleep disturbances (aOR: 5.1; 95% CI: 1.80-14.45; p=0.002) and depression (aOR: 33.91; 95% CI: 12.32-93.33; p<0.001) while depression was strongly associated with dissatisfaction with working conditions (aOR: 3.99; 95% CI: 1.49-10.65; p=0.006), the irregular wearing of protective masks (aOR: 3.94; 95% CI: 1.33-11.66; p=0.013) and anxiety (aOR=51.63; 95% CI: 17.74-150.25; p<0.001). Conclusion: secondary school teachers in Tunisia are characterized by a high rate of anxiety and depressive disorders which are related to personal and professional factors on which we can act by supplying of educational institutions by protective masks, the implementation of programs for adjusting working conditions and the practice of non-pharmacological interventions for insomnia management.

Chronic blepharitis due to Demodex: A prospective study in Sfax (Tunisia).

INTRODUCTION: Chronic blepharitis is a common cause of eye irritation and dryness. They are often treated without regard to causal factors such as parasites which are rarely mentioned. AIM: To describe the role of Demodex in the pathogenesis of chronic blepharitis, to analyze the epidemiological, clinical, diagnostic and therapeutic particularities. METHODS: This is a prospective, case-control study conducted in the mycology parasitology department at the Habib Bourguiba university hospital in Sfax covering 100 cases with chronic blepharitis and 87 control cases. Clinical examination and eyelash removal were performed with direct examination for qualitative and quantitative analysis, before and after treatment. RESULTS: Demodex was significantly more found in patients than in controls (48% vs 13.8%). The quantitative analysis showed a significant difference between the two groups with 52.1% of Demodex (+++) for patients versus 8.3% for controls. Demodex blepharitis were treated with yellow oxid mercure ophthalmic ointment with a good outcome in 81,3%. CONCLUSION: Although it is admitted to be a saprophyte of the skin, a large number of arguments argues for the incrimination of Demodex in the etiopathogenesis of chronic blepharitis, hence the interest of eyelashes examination and a parasitic research in front of any chronic blepharitis resistant to usual treatments. In case of positive research, a specific treatment should be prescribed. Its effectiveness is another argument for the etiological diagnosis.

Access to healthcare for migrants in Tunisia in 2023-2024: Current situation and ethical challenges.

INTRODUCTION: Transformed progressively into a transit country towards Europe but also as a host, Tunisia has seen a diversification of migratory movements since the 2011 revolution, as well as the profiles of migrants who face multiple difficulties that can have an impact on their health. AIM: This update aimed to expose the situation of migrants in Tunisia regarding access to healthcare, and to raise the ethical issues that result from it. RESULTS: Providing care to vulnerable individuals, especially migrants, compels us to reevaluate our practices and question ourselves. Ethical questioning is constant to determine how to do well and not harm. The reflection on this more humane "social medicine" comprehending the patient in its entirety, is only in its beginnings. The critical health status of the poorest populations and their extreme vulnerability do not only call for adapted and specific care measures but also a more comprehensive questioning of social ties and the place that our society grants to the weakest and excluded. CONCLUSION: Migration must be considered as a central issue of the ethics of the health of a population in order to provide quality care without prejudice.

An update on the access to inpatient rehabilitation facilities across Tunisia in 2023.

INTRODUCTION: Considering the growing global need and the complexity of health conditions, an intensive rehabilitation in inpatient departments is fundamental. Yet, in Tunisia, the distribution of Inpatient Rehabilitation Facilities is not illustrated. AIM: To perform an update concerning the rehabilitation's beds-ratio /1000 Tunisian-inhabitants in 2023. METHODS: Data were collected from the Tunisian Ministry of Health, the Eastern Mediterranean Regional Office, and the National Institute of Statistics websites. RESULTS: The findings revealed a total number of rehabilitations' beds 132 among a total of 20000 hospital beds with a rehabilitations' beds-ratio equal to 0.01/1000 inhabitants. Only three Inpatient Rehabilitation Facilities were identified in Tunisia covering the Greater Tunis, North East, and Center east districts. There was inequity of distribution since the beds ratio is 1.07/1000 in the North east, 0.02/1000 in the Greater Tunis and 0 in the North West and the South of Tunisia. CONCLUSION: This update highlighted the alarmingly low rehabilitation's beds-ratio in Tunisia, coupled to a significant regional disparity. Increasing beds in the existing Inpatient Rehabilitation Facilities and extending outpatient rehabilitation departments with inpatient units might be considered urgent solutions.

Blastococcus brunescens sp. nov., a member of the Geodermatophilaceae isolated from sandstone collected from the Sahara Desert in Tunisia.

The taxonomic position of strain BMG 8361T, isolated from sandstone collected in the Sahara Desert of Southern Tunisia, was refined through a polyphasic taxonomic investigation. Colonies of BMG 8361T were pale-orange coloured, irregular with a dry surface and produced a diffusible pink or brown pigment depending on media. The Gram-positive cells were catalase-positive and oxidase-negative. The strain exhibited growth at 10-40 °C and pH values ranging from 5.5 to 9.0, with optima at 28-35 °C and pH 6.5-8.0. Additionally, BMG 8361T demonstrated the ability to grow in the presence of up to 1 % NaCl (w/v) concentration. The peptidoglycan of the cell wall contained meso-diaminopimelic acid, glucose, galactose, xylose, ribose, and rhamnose. The predominant menaquinones consisted of MK-9(H4) and MK-9. The main polar lipids were phosphatidylcholine, phosphatidylinositol, glycophosphatidylinositol, diphosphatidylglycerol, phosphatidylethanolamine, and two unidentified lipids. Major cellular fatty acids were iso-C16 : 0, iso-C16 : 1 h, and C17 : 1 ω8c. Phylogenetic analyses based on both the 16S rRNA gene and whole-genome sequences assigned strain BMG 8361T within the genus Blastococcus. The highest pairwise sequence similarity observed in the 16S rRNA gene was 99.5 % with Blastococcus haudaquaticus AT 7-14T. However, when considering digital DNA-DNA hybridization and average nucleotide identity, the highest values, 48.4 and 86.58 %, respectively, were obtained with Blastococcus colisei BMG 822T. These values significantly undershoot the recommended thresholds for establishing new species, corroborating the robust support for the distinctive taxonomic status of strain BMG 8361T within the genus Blastococcus. In conjunction with the phenotyping results, this compelling evidence leads to the proposal of a novel species we named Blastococcus brunescens sp. nov. with BMG 8361T (=DSM 46845T=CECT 8880T) as the type strain.

Therapeutic education of patients with coronary heart disease: Impact of digital platform monitoring in preventing major cardiovascular events in Tunisia: Study protocol.

BACKGROUND: Faced with the increase in the number of chronic diseases with the aging of the population, and with the observation of the insufficiency of therapeutic control, a new need has emerged, that of having a patient as a partner in care. METHODS: This study is a randomized controlled trial. Patients with coronary heart disease will be recruited from one clinical site and randomly assigned into two groups: the intervention group and the control group. All participants will be followed up for a total of one year (with three-time points for data collection). Patients who are assigned to the intervention group will receive therapeutic education at first. The digital platform will then allow healthcare providers to accompany them outside the hospital walls. The primary outcome is the incidence of major cardiovascular events within one year of discharge. Main secondary outcomes include changes in health behaviors, medication adherence, and quality of life score. The digital platform is a multi-professional telemonitoring platform that allows care teams to accompany the patient outside the hospital walls. It allows the collection and transmits information from the patient's home to the therapeutic education team. All data will be secured at a certified host. The patient application provides data on compliance, adherence to physical activity (number of steps taken per day), adequate diet (weight gain, food consumed during the meal, compliance with low-salt or salt-free diet, diabetic diet), smoking cessation, as well as medication adherence. Access to educational tools (digital media) is provided to all initial program participants. These tools will be updated annually by the rehabilitation team on the recommendations. The platform also offers the possibility of organizing an individual or group remote educational session (videoconference modules allowing group and individual sessions), a secure integrated caregiver-patient messaging system. The control group will receive the usual controls at the hospital. DISCUSSION: To offer a complete solution of care to our patients, we have thought of setting up a digital platform that aims to monitor the patient and strengthen their abilities to manage their condition daily. This pilot experience could be generalized to several services and disciplines. It could be used in several research works. TRIAL REGISTRATION: Trial registered with the Pan African Clinical Trial Registry (PACTR202307694422939). URL: https://pactr.samrc.ac.za/TrialDisplay.aspx?TrialID=24247.

First report of Sarcocystis falcatula in naturally infected Razorbill auks (Alca torda) collected in Tunisian Mediterranean Sea shores.

Sarcocystis spp. are apicomplexan cyst-forming parasites that can infect numerous vertebrates, including birds. Sarcosporidiosis infection was investigated in three muscles (breast, right and left thigh muscle) and one organ (heart) of four Razorbill auks (Alca torda) stranded between November and December 2022 on the shores of the Mediterranean Sea in Nabeul and Bizerte governorates, Northern Tunisia. Two of the four tested A. torda were PCR positive for 18S rRNA Sarcocystis spp. gene. Among the examined 16 muscles/organs, only one breast and one right thigh were Sarcocystis spp. PCR-positive (12.5% ± 8.3, 2/16). Our results showed a relatively high molecular prevalence of Sarcocystis spp. in Razorbill auks (A. torda). Sarcocystis spp. sequence described in the present study (GenBank number: OR516818) showed 99.56-100% identity to Sarcocystis falcatula. In conclusion, our results confirmed the infection of Razorbill auks (A. torda) by S. falcatula. Further research is needed on different migratory seabirds' species in order to identify other Sarcocystis species.

Activities of daily living, self-efficacy and motor skill related fitness and the interrelation in children with moderate and severe Developmental Coordination Disorder.

BACKGROUND: Children with Developmental Coordination Disorder (DCD) are diagnosed based on poor motor skills that impact their daily activities. However, this may also lead to lower predilection and participation in physical activities and a higher risk to develop health problems. OBJECTIVE: To determine motor skill related levels in children with moderate and severe DCD and compare that to typically developing children (TD). The study also aimed to determine the level of activities of daily living (ADL) as reported by their parent and self-efficacy as reported by the children. Lastly, the relation of motor skill related fitness, ADL, and self-efficacy has been examined. METHODS: A cross-sectional study has compared TD children (n = 105) and children with DCD (n = 109; 45 moderate DCD and 64 severe DCD) from elementary schools in Tunisia between 7 and 10 years of age. The DCDDaily-Questionnaire and Children's Self-perceptions of Adequacy in and Predilection for Physical Activity Questionnaire have been used to determine ADL and adequacy towards physical activity, respectively. The PERF-FIT has been used to measure motor skill related fitness levels. RESULTS: Large group differences (p = 0.001) were found for ADL and all domains of self-efficacy between TD and DCD children. However, ADL and self-efficacy were not different between moderate and severe DCD. Motor skill related fitness was significantly lower (p = 0.01) for children with DCD than TD children, and between children with moderate and severe DCD. The relation between self-efficacy and DCDDaily-Q was different in the two DCD groups. Slow motor learning was associated with lower perceived enjoyment in physical education in the moderate DCD group, and with lower perceived adequacy in physical education in the severe DCD group. CONCLUSIONS: Children with DCD participate and enjoy physical activity less than their peers. This combination of lower participation, lower predilection to physical activity and lowered motor skill-related fitness is a concern for the present and future health status of children with DCD.

Benefit of intrapleural fibrinolytic therapy in the treatment of complicated parapneumonic effusion and empyema.

Our study aimed to assess the benefit of intrapleural fibrinolysis before resorting to surgery to treat complicated parapneumonic effusion and empyema. We conducted a retrospective and descriptive study, including all patients hospitalized in the intensive care unit (ICU) of the Abderhaman Mami hospital, Tunisia for empyema treated with instillation of intrapleural fibrinolytic therapy between the 1st January 2000 and 31st December 2016. In all patients, empyema was diagnosed on clinical features, imaging findings (chest X-ray, thoracic echography and/or computed tomography (CT), and microbiological data. The fibrinolytic agent used was streptokinase. The efficiency of intrapleural fibrinolytic therapy was judged on clinical and paraclinical results. Among 103 cases of complicated parapneumonic effusion and empyema, 34 patients were included. The mean age was 34 years [15-81] with a male predominance (sex ratio at 2.77). Median APACH II score was 9. Fifty (50%) of the patients (n=17) had no past medical history; addictive behavior was described in 17 patients (50%). All patients were admitted for acute respiratory failure and one patient for septic shock. Pleural effusion was bilateral in 7 patients. Bacteria isolated were Streptococcus pneumonia (6 cases), Staphylococcus aureus (3 cases, including one which methicillin-resistant), Staphylococcus epidermidis (1 case), anaerobes (5 cases), and Klebsiella pneumoniae (1 case). First-line antimicrobial drug therapy was amoxicillin-clavulanate in 20 patients. A chest drain was placed in all cases in the first 38 hours of ICU admission. The median number of fibrinolysis sessions was 4 [2-9] and the median term of drainage was 7 days [3-16]. No side effects were observed. Video-assisted thoracoscopic surgery was proposed in 5 patients. The median length of hospitalization stay was 15 days [6-31]. One patient died due to multi-organ failure.

Inflammatory breast cancer: Epidemiologic data and therapeutic results.

Since the early description more than a century ago, inflammatory breast cancer (IBC) remains an aggressive disease, with a different geographic repartition, with the highest ones incidence reported in the North of Africa (Tunisia, Algeria, Morocco, and Egypt), and the lowest incidence in Western countries (USA, Europe…). In this study, we reviewed the literature using the Surveillance, Epidemiology, and End Results (SEER) database compared to other published series. We observed that in the high incidence areas (North of Africa) when compared to "classical" breast cancer, IBC was associated to younger age (less than 50 years) with rapid evolution of signs and symptoms (in less than 3 up to 6 months), and more aggressive clinical and histopathological-molecular parameters, due to the predominance of triple-negative and HER2+ subtypes in around 60% of cases. An epidemiologic trend was observed in both high and low incidence areas since the eighties are towards reduction of IBC prevalence. Concerning Tunisia, in comparison with the historical series of the 1980s, the incidence decreased in part by applying more stringent diagnostic criteria but also probably due to a slight improvement of the socio-economic level (SEL). This trend was also observed in the US, due to the efforts of collaborative IBC groups from MD Anderson Cancer Center (MDACC), Duke and IBC patient advocacy groups. Therapeutic results are slightly better due to the standardization of a multidisciplinary approach and the use of combined primary chemotherapy and/or targeted therapies (especially in HER2 positive patients), followed by mastectomy plus radiotherapy. The 5-year overall and disease-free survival is at more than 60%, related to an IBC mortality decrease observed in the cohorts of patients treated in the last decade.

Epidemiological Analyses of the First Incursion of the Epizootic Hemorrhagic Disease Virus Serotype 8 in Tunisia, 2021-2022.

Epizootic hemorrhagic disease (EHD) is a non-contagious arthropod-transmitted viral disease and a World Organization for Animal Health (WOAH)-listed disease of domestic and wild ruminants since 2008. EHDV is transmitted among susceptible animals by a few species of midges of genus Culicoides. During the fall of 2021, a large outbreak caused by the epizootic hemorrhagic disease virus (EHDV), identified as serotype 8, was reported in Tunisian dairy and beef farms with Bluetongue virus (BTV)-like clinical signs. The disease was detected later in the south of Italy, in Spain, in Portugal and, more recently, in France, where it caused severe infections in cattle. This was the first evidence of EHDV-8 circulation outside Australia since 1982. In this study, we analyzed the epidemiological situation of the 2021-2022 EHDV outbreaks reported in Tunisia, providing a detailed description of the spatiotemporal evolution of the disease. We attempted to identify the eco-climatic factors associated with infected areas using generalized linear models (GLMs). Our results demonstrated that environmental factors mostly associated with the presence of C. imicola, such as digital elevation model (DEM), slope, normalized difference vegetation index (NDVI), and night-time land surface temperature (NLST)) were by far the most explanatory variables for EHD repartition cases in Tunisia that may have consequences in neighboring countries, both in Africa and Europe through the spread of infected vectors. The risk maps elaborated could be useful for disease control and prevention strategies.

Primary breast sarcomas: A 13 case-series study treated in university hospital in central Tunisia over a 25-year period.

AIM: To retrospectively study the therapeutic modalities of primary breast sarcomas in view of the data of a local Tunisian experience. METHODS: It is a monocentric, descriptive, retrospective study including 13 cases of primary breast sarcoma treated over a period of 25 years (1995-2020) in the oncological radiotherapy department of a university hospital in Sousse, Tunisia. RESULTS: In our study, 13 cases of non-metastatic breast sarcomas that has been identified, divided into ten cases of phyllodes sarcomas and three cases of non-phyllodes sarcomas.Surgically, all our patients had a mastectomy. Among them, seven underwent a lymph node procedure: five underwent axillary lymph node dissection, and two others had primary axillary lymph node biopsy. For the adjuvant treatment, all the patients included in our study received radiotherapy and seven received chemotherapy. Local recurrence occurred on the operative scar in one patient after completion of radiation therapy. Metastatic relapse was described in five patients. The time to onset of metastases varied between two months and five years. Nevertheless, a complete remission was noted in 6 patients with a follow-up varying from four years to 20 years. Two patients were lost to follow-up. CONCLUSION: Breast sarcomas remain a very rare entity of aggressive tumors.The therapeutic approach is poorly codified. For this reason, the therapeutic decision should always be discussed in a multidisciplinary assessment.

Geochemical, mineralogical records, and statistical approaches in establishing sedimentary in the environment of a Mediterranean coastal system: case of Sebkha El-Guettiate (southeastern Tunisia).

The current study was conducted within the context of the Holocene era in Sebkha El-Guettiate, located in southeastern Tunisia. The aim was to determine the factors influencing the geochemical and mineralogical composition of sediments and to elucidate the sedimentary characteristics of the Holocene within the Sebkha core. We examined a sediment core extending 100 cm from this Sebkha, subjecting it to comprehensive analysis to uncover its sedimentological, mineralogical, and geochemical properties. Several techniques were employed to strengthen and validate the connections between geochemical and mineralogical analyses, including X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM), and infrared (IR) spectroscopy, among others. Furthermore, statistical analyses utilizing principal component analysis (PCA) were applied to the results of the geochemical and mineralogical studies, aiding in the identification of patterns and relationships. A comprehensive mineralogical assessment of the core's sediments revealed the presence and interpretation of carbonate minerals, evaporite minerals, and detrital minerals. Through the application of infrared (IR) spectrometer techniques to all sediment samples, we gained insight into the mineralogical components and the distribution of key elements such as quartz, kaolinite, calcite, feldspar, and organic carbon. The geochemical composition demonstrated a clear dominance of silica (SiO2), accompanied by fluctuations in carbonate percentages (CaCO3). The prominent major elements, primarily magnesium (Mg) and calcium (Ca) originating from dolomitization, sodium (Na) and chlorine (Cl) from halite, and calcium (Ca) from gypsum, exhibited varying levels. Results from Rock-Eval 6 pyrolysis indicated that the organic matter within the sediments is generally a mixture of terrestrial and aquatic origins. This study provides practical information that underscores the diverse origins contributing to Sebkha sediment formation, often influenced by saline systems.

[Predictive factors of severity and mortality in acute community-acquired pneumonia : results of a monocentric study in Tunisia]. / Facteurs prédictifs de gravité et de mortalité des pneumonies aiguës communautaires :étude monocentrique en Tunisie.

Community-acquired pneumonia (CAP), a frequent reason for hospitalization in pulmonology, is a major cause of morbidity and mortality in adults. METHODS: It is a retrospective, descriptive and analytical study including patients hospitalized for CAP. We studied the predictors of NIV, ICU transfer and hospital mortality. RESULTS: we included 50 patients (mean age: 56.3 ± 12.8 years). Predictive factors of NIV were PaCO2 ≥ 45 mmHg [Odds Ratio (OR): 15.45, 95 % Confidence Interval (IC): 1.29-184.7], pH ≤ 7.35 (OR: 6.42;1.72-23.9), Fine ≥ 57.5 (OR: 17.36;4.32-693.9) and CURB-65 ≥ 2 (OR: 13.54;1.73-105.7). Taking antibiotics before hospitalization (OR: 1.92;1.08-3.49), PaO2 ≤ 60 mmHg (OR: 4.15;1.27-13.60), Fine score ≥ 100 (OR: 13.54;1.73-105.7) and CURB-65 ≥ 2 (OR: 7.50;1.44-36.9) were associated with the admission in the ICU. PH ≤ 7.35 (OR: 6.39;1.77-23.2) and Fine score ≥ 100 (OR: 8.86;3.33-25.2) were correlated with mortality. CONCLUSION: Arterial pH ≤ 7.35, hypoxemia, hypercapnia, CURB-65 ≥ 2, Fine ≥ 100 and taking antibiotics before hospitalization are predictive factors of a poor prognosis of CAP.

Les pneumonies aiguës (PAC), motifs fréquents d'hospitalisation en pneumologie, constituent une cause majeure de morbidité et de mortalité chez l'adulte. Méthodes : Etude rétrospective, descriptive et analytique incluant les patients hospitalisés pour PAC. Nous avons étudié les facteurs prédictifs de recours à la ventilation non invasive (VNI), de transfert en réanimation et de mortalité hospitalière. Résultats : Au total, 50 cas de PAC ont été colligés (âge moyen : 56,3 ± 12,8 ans). Les facteurs prédictifs de recours à la VNI étaient la PaCO2 ≥ 45 mmHg [Odds Ratio (OR) : 15,45, Intervalle de confiance (IC) 95 % : 1,29-184,7], le pH artériel ≤ 7,35 (OR : 6,42; 1,72-23,9), un score de Fine ≥ 57,5 (OR : 17,36;. 4,32-69,9), et un score CURB-65 ≥ 2 (OR : 13,54; 1,73-105,7). La prise d'antibiotiques avant l'hospitalisation (OR : 1,92 ;1,08-3,49), la PaO2 ≤ 60 mmHg (OR : 4,15; 1,27-13,6), un score de Fine ≥ 100 (OR : 13,54; 1,73-105,7) et un score CURB-65 ≥ 2 (OR : 7,50;1,44-36,9) étaient associés au transfert en réanimation. Le pH ≤ 7,35 (OR : 6,39; 1,77-23,2) et un score de Fine ≥ 100 (OR : 8,86; 3,33-25,2) étaient corrélés à la mortalité. Conclusion : Un pH ≤ 7,35, l'hypoxémie, l'hypercapnie, un score CURB-65 ≥ 2, un score Fine ≥ 100 et la prise d'antibiotiques avant l'hospitalisation sont des facteurs prédictifs d'un mauvais pronostic des PAC.

Prevalence and associated factors of unhealthy diet among adolescents: cross-sectional study among Tunisian high school students.

OBJECTIVES: According to World Health Organization (WHO),Unhealthy Diet (UD)is a major risk factor for chronic diseases. That's why it is important to study the UD and its associated factors. Our study aimed to describe the dietary behavior of young high school students and determine associated factors of UD. METHODS: A cross-sectional study was carried out among students of seven high schools in center-eastern Tunisia during the academic year 2021/2022. Data collection was carried out in April2022 by questionnaires. The questions concerned the socio-demographic characteristics, food habits and physical activity. WHO defined UD as the consumption of less than five fruits and vegetables per day. Data analysis was done using SPSS software. RESULTS: A total of 740 adolescents were included. The mean age was17±1.16 years with extremes ranging from 14to19 years. Sex-ratio was 0.66. UD was found among 91.6 % of the study population. At multivariate analysis, eating cake (aOR=4.062; CI [1.685-9.795]; p=0.002),eating fried-food (aOR=3.239; CI [1.118-9.385]; p=0.03)and consuming sweets (aOR=3.263; CI [1.666-6.394]; p=0.001)were independent risk factors of UD. In the other hand, regular physical activity (aOR=0.524; CI [0.294-0.936]; p=0.029)and having breakfast regularly (aOR=0.523; CI [0.297-0.923]; p=0.025)were independent protective factors of UD. CONCLUSIONS: The findings of this study showed an alarming prevalence of UD. Therefore, it is mandatory to establish effective strategies to support healthy diets and physical activity among adolescents in order to reduce non-communicable diseases related to UD.

Phylogeographic Dynamics of H9N2 Avian Influenza Viruses in Tunisia.

Avian influenza virus subtype H9N2 is endemic in commercial poultry in Tunisia. This subtype affects poultry and wild birds in Tunisia and poses a potential zoonotic risk. Tunisian H9N2 strains carry, in their hemagglutinins, the human-like marker 226 L that is most influential in avian-to-human viral transmission. For a better understanding of how ecological aspects of the H9N2 virus and its circulation in poultry, migratory birds and environment shapes the spread of the dissemination of H9N2 in Tunisia, herein, we investigate the epidemiological, evolutionary and zoonotic potential of seven H9N2 poultry isolates and sequence their whole genome. Phylogeographic and phylodymanic analysis were used to examine viral spread within and among wild birds, poultry and environment at geographical scales. Genetic evolution results showed that the eight gene sequences of Tunisian H9N2 AIV were characterized by molecular markers involved with virulence and mammalian infections. The geographical distribution of avian influenza virus appears as a network interconnecting countries in Europe, Asia, North Africa and West Africa. The spatiotemporal dynamics analysis showed that the H9N2 virus was transmitted from Tunisia to neighboring countries notably Libya and Algeria. Interestingly, this study also revealed, for the first time, that there was a virus transmission between Tunisia and Morocco. Bayesian analysis showed exchanges between H9N2 strains of Tunisia and those of the Middle Eastern countries, analysis of host traits showed that duck, wild birds and environment were ancestry related to chicken. The subtypes phylodynamic showed that PB1 segment was under multiple inter-subtype reassortment events with H10N7, H12N5, H5N2 and H6N1 and that PB2 was also a subject of inter-subtype reassortment with H10N4.

Dynamic of SARS-CoV-2 variants circulation in Tunisian pediatric population, during successive waves, from March 2020 to September 2022.

The emergence of SARS-CoV-2 variants has led to several cases among children. However, limited information is available from North African countries. This study describes the SARS-CoV-2 strains circulating in Tunisian pediatric population during successive waves. A total of 447 complete sequences were obtained from individuals aged from 13 days to 18 years, between March 2020 and September 2022: 369 sequences generated during this study and 78 ones, available in GISAID, previously obtained from Tunisian pediatric patients. These sequences were compared with 354 and 274 ones obtained from Tunisian adults and a global dataset, respectively. The variant circulation dynamics of predominant variants were investigated during the study period using maximum-likelihood phylogenetic analysis. Among the studied population, adolescents were the predominant age group, comprising 55.26% of cases. Twenty-three lineages were identified; seven of which were not previously reported in Tunisia. Phylogenetic analysis showed a close relationship between the sequences from Tunisian adults and children. The connections of sequences from other countries were variable according to variants: close relationships were observed for Alpha, B1.160 and Omicron variants, while independent Tunisian clusters were observed for Delta and B.1.177 lineages. These findings highlight the pivotal role of children in virus transmission and underscore the impact of vaccination on virus spread. Vaccination of children, with booster doses, may be considered for better management of future emergences.

The effect of therapeutic education program on quality of life among type 2 diabetic North-African patients: a randomized controlled trial.

INTRODUCTION: Type 2 Diabetes Mellitus (T2DM) is a chronic non-communicable disease with major impact on health in general and quality of life (QoL) in particular. The ultimate goal of all health interventions is to reduce the burden of this disease. AIM: To evaluate the effect of therapeutic education program on the QoL among patients with T2DM. METHODS: Between May 2021 and July 2022, 320 outpatients were enrolled in a randomized controlled trial in Sfax, Tunisia. The experimental group received the therapeutic education program, whereas the control group received only standard care. For data collection, the Arabic version of the Diabetes Quality of Life (DQoL-Arabic) questionnaire was used. RESULTS: In total, 263 patients completed the intervention, 132 in the experimental group and 131 in the control group. In terms of the main baseline characteristics, the two groups were comparable. After the intervention, there was a significant difference in all domains of QoL scores (median [interquartile]) between the experimental and control groups: satisfaction (3.14 [2.64-3.36] vs. 3.57 [3.43-3.71], p<0.001, respectively), impact (2.09 [1.91-2.36] vs. 2.45 [2.27 2.64], p<0.001, respectively) and worries (2.50 [2.25-2.75] vs. 3.00 [2.75 3.14], p<0.001, respectively). The QoL improves over time in the experimental group (3.01 [2.79-3.17] vs. 2.59 [2.21-2.80], p<0.001, respectively) and remains comparable in the control group (2.99 [2.81-3.14] vs. 3.01 [2.81-3.15], p=0.724, respectively). CONCLUSIONS: The benefits of implementing an educational program among patients with T2DM are observed in terms of all QoL domains.

Risk factors for treatment failure in multidrug resistant tuberculosis in Tunisia: An analytic study.

INTRODUCTION-AIM: The emergence of multidrug resistant tuberculosis (MDR-TB) is a threat to global public health. The aim of our study was to determine risk factors for treatment failure in MDR-TB. METHODS: Retrospective study conducted between January 2000 and March 2019 including patients with MDR-TB. Characteristics of patients with therapeutic failure were compared to cured ones. Logistic regression analysis was used to identify risk factors for treatment failure. RESULTS: Our study included 140 patients aged of 42±13 years (18-80). Fifty-seven percent of patients had treatment success and 12% had treatment failure. In multivariate logistic regression analysis, treatment failure was associated with age over 45 years (OR=1.05; 95%CI, 1.024-7.736;p=0.014), primary education level and illiteracy (OR=5.022; 95%CI, 1.316-19.161;p=0,018), history of incarceration (OR=3.291; 95%CI, 1.291-21.083;p=0.016), undernutrition (OR=4.544; 95%CI, 2.304-54.231;p=0,027), extensive TB (OR=6.406; 95%CI, 1.761-23.922; p=0.038), initial high grade positive smears (OR=1.210; 95%CI, 1.187-32.657; p=0.045), positive smear culture at 90 days of treatment (OR=6.871, 95%CI, 3.824-23.541; p=0.003), poor adherence (OR=6.110; 95%CI, 2.740-12.450; p=0.021) and occurrence of psychiatric adverse events (OR=3.644 95%CI, 2.560- 27.268; p=0.041). CONCLUSION: Therapeutic education, nutritional and psychological support and close follow-up are strongly recommended to optimize the prognosis of MDR-TB.

Impact of Covid 19 on Primary healthcare in Tunisia.

INTRODUCTION: Public primary healthcare facilities, the cornerstone of the Tunisian health system, were impacted by the Covid 19 crisis as all health systems in the world. AIM: This study aims to assess this impact of the pandemic. METHODS: We analyzed the budgetary evolution of the basic healthcare group (BHG) of Medenine and Djerba between 2019 and 2020. Similarly, we examined the evolution of all the activities of BHG of Medenine. This analysis was also completed by a semi-structured questioning with a regional expert. RESULTS: Our results showed an increase in expenditure, a decrease in revenue (12.4% for GSB of Medenine and 10.8% for BHG of Djerba), and an accumulation of outstanding payment. BHG's activities have been affected by the pandemic. We showed that stomatology and vaccine activities were well maintained during the pandemic. However, we noted a regression in the number of patients and some illnesses. Activity related to child health and health education has significantly decreased. This impact has had and will have repercussions on the epidemiological state of the population. Despite the intervention of the regional management in terms of organization, training and strengthening of equipment and human resources, the pandemic has generally impacted the operation process of these establishments, which are already facing several challenges. CONCLUSION: We recommend above all to activate the already existing opportunities to replenish the financial resources of primary healthcare facilities, to improve work environment and continuous professional development and to computerize the data and its analysis according to a scientific approach.
