Navigating the Factors Affecting Functional Impairment in Spondyloarthritis.

Objectives: This study aimed to assess the predictive factors of functional impairment in spondyloarthritis (SpA) patients assessed with bath ankylosing spondylitis functional index (BASFI) and Lequesne Index (LI). Methods: This retrospective study was conducted at the Rheumatology Department of Mohamed Kassab Institute of Orthopedics, Manubah, Tunisia, and collected data from 2008 to 2019 over a period of 4 months (August to November 2019). Socio-demographic and disease-related data of SpA patients were collected. Disease activity was assessed using the bath ankylosing spondylitis-global score (BASG-s) and the bath ankylosing spondylitis disease activity index (BASDAI). The spinal mobility was evaluated by the bath ankylosing spondylitis metrology index (BASMI). Structural progression was evaluated with the bath ankylosing spondylitis radiologic index (BASRI) and modified stoke ankylosing spondylitis spine score (mSASSS). A multivariate analysis was done to search for predictive factors associated with BASFI and LI. Results: A total of 263 patients were included. The mean age was 38.9 ± 12.7 years and the gender ratio was 2.7. The mean age of onset of SpA was 27.6 ± 10.8 years and disease duration was 11.3 ± 9.5 years. Occupation was significantly associated with BASFI and LI scores. A significant functional impact was notably correlated with a long duration of the disease. The two scores were correlated with a limitation of spinal mobility (BASMI), a greater disease activity (BASDAI and erythrocyte sedimentation rate) and a greater impact of the disease on health status (BASG-s). Significant functional impairment was also correlated with structural impairment (mSASSS, BASRI and sacroiliitis grade). The variables independently related to BASFI were the mSASSS score and the BASDAI. The variables independently related to LI were profession (unemployed subjects had higher scores), the mSASSS score and the BASMI. Conclusion: Occupation, disease activity, mobility and structural progression predicted functional impairment in Tunisian SpA patients.

Dynamics of SARS-CoV-2 antibodies after natural infection: insights from a study on Pasteur Institute of Tunis employees.

This study aimed to assess the kinetics of antibodies against the SARS-CoV-2, following natural infection in a cohort of employees of the Institut Pasteur de Tunis (IPT) and to assess the risk of reinfection over a 12-months follow-up period. A prospective study was conducted among an open cohort of IPT employees with confirmed SARS-CoV-2 infection that were recruited between September 2020 and March 2021. Sera samples were taken at 1, 3, 6, 9 and 12 months after confirmation of COVID-19 infection and tested for SARS-CoV-2-specific immunoglobulin G (IgG) antibodies to the spike (S-RBD) protein (IgG anti-S-RBD) and for neutralizing antibodies. Participants who had an initial decline of IgG anti-S-RBD and neutralizing antibodies followed by a subsequent rise in antibody titers as well as those who tested positive for SARS-CoV-2 by RT-PCR after at least 60 days of follow up were considered as reinfected. In total, 137 individuals were included with a mean age of 44.7 ± 12.3 years and a sex-ratio (Male/Female) of 0.33. Nearly all participants (92.7%) were symptomatic, and 2.2% required hospitalization. Among the 70 participants with three or more prospective blood samples, 32.8% were reinfected among whom 11 (47.8%) reported COVID-19 like symptoms. Up to 12 months of follow up, 100% and 42.9% of participants had detectable IgG anti-S-RBD and neutralizing antibodies, respectively. This study showed that humoral immune response following COVID-19 infection may persist up to 12 months after infection despite the potential risk for reinfection that is mainly explained by the emergence of new variants.

Retrospective Analysis of Clinical Characteristics and Disease Outcomes in Children and Adolescents Hospitalized Due to COVID-19 Infection in Tunisia.

Due to low susceptibility of coronavirus disease of 2019 (COVID-19) in children, limited studies are available regarding COVID-19 in the pediatric population in Tunisia. The current study evaluated the incidence, clinical characteristics, and outcomes of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infection among children hospitalized at Béchir Hamza Children's Hospital. A retrospective cohort analysis was conducted using the hospital database between March 2020 and February 2022 with children aged ≤15 years with SARS-CoV-2 infection (confirmed by RT-PCR). A total of 327 COVID-19 hospitalized patients with a mean age of 3.3 years were included; the majority were male. Neurological disease (20%) was the most common comorbidity, while fever (95.3%) followed by cough (43.7%) and dyspnea (39.6%) were the most frequent symptoms reported. Severe disease with oxygen requirement occurred in 30% of the patients; 13% were admitted in the Intensive Care Unit. The overall incidence rate of COVID-19 hospitalization (in Tunis governorates) was 77.02 per 100,000 while the inpatient case fatality rate was 5% in the study population. The most prevalent circulating variant during our study period was Delta (48.8%), followed by Omicron (26%). More than 45% of the study population were <6 months and one-fourth (n = 25, 26.5%) had at least one comorbidity. Thus, the study findings highlight the high disease burden of COVID-19 in infants.

[Retrospective study of 60 cases of uterine rupture at the Maternity Center of Monastir, Tunisia]. / Etude rétrospective sur 60 cas de rupture utérine du centre de maternité de Monastir, Tunisie.

Uterine rupture is a life-threatening obstetric complication. The purpose of this study was to investigate the epidemiological features, maternal and foetal prognosis and different treatment options for uterine rupture in healthy and scarred uteri. We conducted a retrospective monocentric descriptive and analytical study of 60 cases of uterine rupture collected in the Department of Gynaecology-Obstetrics of the Center of Maternity and Neonatology, Monastir, from 2017 to 2021. Patients were classified according to the presence or absence of a uterine scar. Sixty patients were enrolled in the study. The majority of cases of rupture occurred in patients with scarred uterus (n=55). The most common clinical sign was abnormal foetal heart rate. No maternal deaths were recorded and perinatal mortality rate was 11%. Mean BMI, fetal macrosomia rate and mean parity were significantly higher in the healthy uterus group than in the scarred uterus group (p=0.033, 0.018, and 0.013, respectively). The maternal complications studied (post-partum haemorrhage, hysterectomy, blood transfusion, prolonged hospitalisation) were significantly more frequent in patients with unscarred uterine rupture (p=0.039; p=0.032; p=0.009; p=0.025 respectively). Uterine rupture is a life-threatening obstetrical event for the foetus and the mother. Fetal heart rate abnormality is the most common sign associated with uterine rupture. Management is based on conservative treatment in most cases. Patients with scarred uterus have a better prognosis.

[Prevalence and predictors of post-traumatic stress disorder in road traffic accidents]. / Prévalence et facteurs prédicteurs des troubles post-traumatiques chez les accidentés de la voie publique.

Introduction: trauma-related disorders following a road accident have both a health and an economic impact. Methods: we conducted a prospective study to determine the prevalence of these disorders, and to identify risk factors in subjects victims of road accidents and hospitalized in the Department of Orthopedic Surgery and Traumatology of the University Hospital Center of Sfax-Tunisia. Results: a total of sixty-ten subjects were included in this study. The prevalence of acute stress disorder was 37.1% and was associated with female sex, low educational level, previous medical and surgical history, passivity during the accident, severity of injuries and the presence of anxious and depressive symptoms. Post-traumatic stress disorder was observed in 40% of subjects and was associated with urban residential environment, passivity during the accident and anxious and depressive symptoms. Low scores for functional coping strategies and high scores for dysfunctional coping strategies were significantly associated with both disorders. Low educational level, urban residential environment, high levels of anxiety and depression, and denial coping strategy appear to be independent risk factors for acute stress and post-traumatic stress disorder. Conclusion: It is therefore important to determine the profile of people at greater risk of post-traumatic stress disorder, to enable early diagnosis in victims of road accidents.

Contribution of ethical reasoning learning sessions on medical training.

INTRODUCTION: Ethical reasoning is an important skill for all physicians who often face complex ethical dilemmas in their daily practice. Therefore, medical training should include methods for learning ethical theories and concepts, as well as how to apply them in practical situations. AIM: Assess the contribution of an Ethical Reasoning Learning session to fifth medical students' training through a comparison of results of the same objective and structured clinical examination (OSCE) in the form of simulated interview before and after sessions. METHODS: Four 45- minutes' sessions of Ethical Reasoning Learning (ERL) were implemented during a psychiatry internship for four groups of 5th-year students of the faculty of medicine of Monastir (Tunisia). Each session was divided into 7 parts: introduction, reading of a clinical vignette, brainstorming concerning the problems posed by this clinical situation, classification of the problems, identification of the principles of medical ethics, construction of the ethical matrix, and a conclusion. RESULTS: Fifty-seven students participated in the study divided into 4 groups. We found a significant difference in the means of the OSCE scores before and after the ERL session and a significant difference between the probability of respecting medical secrecy during pre and post-ethical reasoning learning sessions (p <0.001). We have found an effect of ERL sessions on the acquisition of this ethical competence by medical students. CONCLUSION: We learned that an ERL session has improved medical training in ethics applied to psychiatry. Other sessions dealing with other ethical skills are necessary to confirm these results.

Effect of diabetes self-management education on health-related quality of life of Tunisian children with type1 diabetes mellitus and their parents: A randomized controlled trial.

AIM: To assess the effect of diabetes self-management education (DSME) on health related quality of life (HRQoL) of Tunisian children/adolescents with type 1 diabetes mellitus and their parents. METHODS: This monocentral study used a randomized controlled trial design, during five-month intervention and five-month follow-up and including 110 patients (54 in the DSME intervention group and 56 in the Individual Education by Pediatrician (IEP) control group) and their parents. Pediatric Generic Core Quality-of-Life Inventory 4.0-Scale (PedsQL4.0) evaluated HRQoL. RESULTS: At baseline, both groups had similar clinical features and PedsQL4.0 scores (p>0.05). In DSME, clinical outcomes were significantly improved from baseline to follow-up (p<0.001), while in the IEP group, which received no intervention, these outcomes remained unchanged. During follow-up, DSME showed higher PedsQL4.0 scores in parents' proxy-report and children/adolescents self-report (p<0.001). According to parents' proxy-report, PedsQL4.0 scores were significantly higher during follow-up compared to baseline in DSME (p<0.001) while they remained the same in IEP (p>0.05). DSME had higher percentage of change in the PedsQL4.0 scores than IEP (p<0.01). The median change varied from -5.01% to 0% vs 5.41% to 36.36% in IEP and DSME, respectively. CONCLUSION: Encouraging healthcare professionals to incorporate these interventions could enhance the HRQoL of diabetic children and bolster their self-esteem.

Publication of pediatric theses defended at the Tunis Faculty of Medicine: A 15-year study.

INTRODUCTION: The valorisation of thesis through its publication is necessary to enhance its visibility. Few data exist concerning the characteristics of theses defended at the Tunis faculty of medicine. AIM: Examine the publication rate of pediatric theses and identify factors associated with an increased publication rate. METHODS: We conducted a cross-sectional descriptive bibliometric study of pediatric theses defended at the Faculty of Medicine of Tunis over 15 years, from 2006 to 2020. Theses were retrieved from the catalog of the faculty library. Publications had been searched in databases "Pub Med ", and "Google Scholar" until December2021. RESULTS: The study involved 235 pediatric theses. Sixty-eight theses were published, representing 29% of the total. The main topics of published theses were neonatology (16%) and hematology (15%). The language of publication was French and English in 55% and 45% of cases, respectively. All publications in Q1 and Q2 journals were written in English. The only independent factor predicting publication of theses was the very honourable mention with congratulations of the jury and proposal for the thesis prize (p=0,007). CONCLUSION: Additional assessments will be necessary to identify the obstacles to the publication of theses.

Ischemic Stroke in Young Tunisian Adults.

INTRODUCTION: Ischemic Stroke in young adults is a real public health problem; it's a major cause of disability, alters quality of life and has a great socio-economic impact. AIM: determine risk factors and specify the etiology of arterial ischemic stroke in young Tunisian adults. METHODS: In this 5 years retrospective study (2015-2020), we included all young adults (18-50 years) admitted for arterial ischemic stroke (AIS). Risk factors were registered and analyzed. All patients were investigated using a standard protocol: biological tests, brain imaging, carotid ultrasound and cardiac assessment. Additional investigations were carried out at the discretion of the treating physician. The cause of ischemic stroke was classified according to the TOAST criteria. RESULTS: We collected 200 patients with AIS. The mean age was 41.37 years ± 6.99. Traditional vascular risk factors were observed in more than 1/4 patients. A definite cause of stroke was identified in 120 patients. Cardio-embolic causes were the most common among our patients (19%) followed by atherosclerosis of the large arteries (11.5%). Other determined etiologies were found in 27.5% of patients. The etiology remained unclear in 40% of cases: undetermined despite complete investigation in 17.5%, undetermined and incompletely investigated 14.5 % and more than one potential pathomechanisms in 8%. CONCLUSION: Through this study, we demonstrated the diversity of etiology of stroke in young Tunisian adults. Changes of lifestyle are responsible for the occurrence of the traditional risk factors at an early age. Rheumatic heart diseases remain a frequent cause of AIS in our area.

Occupational elbow musculoskeletal disorders in Tunisia: Epidemiology and socio-professional consequences.

INTRODUCTION: Musculoskeletal disorders (MSDs) are as the primary occupational disease (OD) in Tunisia. They can touch the elbow and cause occupational disability. AIMS: Describe the epidemiological and clinical characteristics of elbow MSDs recognized in Tunisia, identify the factors associated with these MSDs and assess their socio-professional impact. METHODS: Retrospective descriptive study of elbow MSDs recognized as compensable OD by the Committees for the Recognition of Occupational Diseases of National Health Insurance Fund, in Tunisia, from 2012 to 2018. RESULTS: We collected 431 cases of elbow MSDs or 8.35% of all recognized MSDs and 11.8% of recognized MSDs during the same period. The average annual incidence was 4.3 cases. Patients had a mean age of 43.59 years and a clear female predominance (82.2%). The largest provider was the textile industry (60.6%). The average length of employment was 16.78 years. Biomechanical factors were repetitive movements (92.8%), forced movements (67.1%) and prolonged static posture (7.4%). These were lateral epicondylitis (79.1%), medial epicondylitis (14.2%) and ulnar nerve syndrome (10.7%). These pathologies were associated with other MSDs including carpal tunnel syndrome (25.8%). These MSDs were responsible for 15,342 days of lost work. The rate of permanent partial incapacity was 10.6% with a job loss in 15.63%. CONCLUSION: Elbow MSDs are responsible for heavy economic and socio-professional consequences justifying the implementation of a preventive strategy adapted within risk sectors.

Mating type and microsatellite genotyping indicate that the Tunisian population of Phyllosticta citricarpa is clonal and thrives only asexually.

Citrus black spot (CBS) caused by Phyllosticta citricarpa was reported for the first time in Tunisia in 2019. This was also the first reported occurrence of the disease in a Mediterranean climate. In Tunisia, CBS is mainly found in lemon (Citrus limon) orchards, and is seldom observed on sweet orange (Citrus × sinensis). This recent finding in North Africa raises questions about how the disease has been able to spread under Mediterranean climatic conditions. In this work, 216 Phyllosticta strains collected from lemon orchards in 2021, 2022 and 2023 throughout the country's main citrus-growing provinces were characterised by species morphological and molecular identification, mating type and Simple Sequence Repeats (SSR) microsatellite genotyping (MLG). P. citricarpa was the only species found to be associated with CBS in Tunisia. Although P. citricarpa is a heterothallic fungal species, potentially able to reproduce both sexually and asexually, a single mating type (MAT 1-1-1) idiomorph was found in the population. In addition, three MLGs were observed, across ten microsatellite loci, one of which was massively represented (93 %), indicating a clonal population. The clonality observed suggests a single recent introduction of the pathogen into the country. These findings support the idea that in Tunisia, P. citricarpa only reproduces asexually by pycniospores, with a relatively limited dispersal potential. This is consistent with the absence of pseudothecia on the leaf litter. These results show that CBS is able to thrive under Mediterranean conditions, even in the absence of sexual reproduction. This should be taken into consideration for CBS risk assessment and management.

What constitutes an obstructive ventilatory impairment in a pediatric population? A study design.

INTRODUCTION: There is no clear consensus as to what constitutes an obstructive ventilatory impairment (OVI) in pediatric populations. AIM: To determine the percentage of children/adolescents having an OVI among those addressed for spirometry after taking into account the definitions advanced by some international scholarly societies [British Columbia (BC), British thoracic-society (BTS), Canadian thoracic society (CTS), European respiratory society and American thoracic society (ERS-ATS), global initiative for asthma (GINA), Irish college of general practitioners (ICGP), national asthma council (NAC), national institute of clinical excellence (NICE), Société de pneumologie de langue française, Société pédiatrique de pneumologie et allergologie (SPLF-SP2A), and South African thoracic society (SATS)]. METHODS: This bi-centric cross-sectional study involves two medical structures in Sousse/Tunisia, and will encompass children/adolescents aged 6-18 years. A medical questionnaire will be administered, clinical and anthropometric data will be collected, and the spirometric data will be measured by two spirometers. The following six definitions of OVI will be applied: i) GINA: Forced expiratory volume in 1 second (FEV1) < 80% and a FEV1/forced vital capacity (FVC) ≤ 0.90; ii) ICGP: FEV1/FVC < 0.70; iii) ERS-ATS or BTS or SATS or SPLF-SP2A or NAC: FEV1/FVC z-score < -1.645; iv) NICE: FEV1/FVC < 0.70 or FEV1/FVC z-score < -1.645; v) CTS: FEV1/FVC < 0.80 or a FEV1/FVC z-score < -1.645; and vi) ERS: "FEV1 z-score or FEV1/FVC z-score" < -1.645 or "FEV1 or FEV1/FVC" < 0.80. EXPECTED RESULTS: The percentage of children/adolescents having an OVI will significantly vary between the six definitions. CONCLUSION: The frequency of OVI in a pediatric population will depend on the definition chosen.

Assessment by mini clinical evaluation exercise (Mini-CEX) in the intensive care unit.

INTRODUCTION: Mini Clinical Evaluation Exercise (mini-CEX) is one of the assessment tools in medical education. It includes three steps: overview of clinical situation, observation and feedback. AIM: To evaluate the feasibility of mini-CEX as a formative assessment tool for medical trainees in 5th year of medicine in a teaching intensive care unit (ICU). METHODS: Single-center qualitative research conducted in ICU during the 2nd semester of the academic year 2022-2023. Seven core clinical skill assessments were done, and the performance was rated on a 9-point scale. An assessment of the method was conducted with both trainees and clinical educators. RESULTS: We conducted six mini-CEX recorded sessions. All medical students had marks under the average of 4.5. In the first period, the highest mark was obtained for counselling skills (4.5). The best score was obtained for clinical judgement (4) in the second period and for management plan (4) in the third period. Most of medical trainees (11 sur 12) were satisfied with the method and feedback was according to them the most useful step. Ten students agreed fully to introduce this assessment tool in medical educational programs. Two medical educators out of three did not practice this method before. They agreed to include mini-CEX in the program of medical education of the faculty of medicine of Tunis. However, they did not agree to use it as a summative assessment tool. CONCLUSION: Our study demonstrates that we can use the mini-CEX in medical teaching. Both trainees and educators were satisfied with the method.

Assessment of muscle strength in chronic low back pain patients: Comparison between isocinetic rehabilitation and conventional rehabilitation.

INTRODUCTION: Chronic low back pain is a public health problem in view of its functional repercussions and the functional rehabilitation is an integral part of its management. AIM: To compare the evolution of muscle strentgh of spinal extensors and flexors in chronic low back pain patients after an isokinetic rehabilitation protocol and a conventional rehabilitation one. METHOD: This was a prospective and comparative study carried out in the Physical Medicine Department of the Tunis Military Hospital over a period of 7 months. Fifty patients were included, randomly divided into two groups of 25. The first group (G1) benefited from an isokinetic rehabilitation protocol and the second one (G2) from a classic active physiotherapy. We performed a clinical (Sorensen test and Shirado test) and isokinetic evaluation of the trunk muscles before and after rehabilitation. RESULTS: The mean age of the general population was 42±8.6 years old. Clinical evaluation showed a deficit in the extensor and flexor muscles of the spine, more important in the extensors in both groups. After rehabilitation, there was a significant improvement in clinical tests of muscular endurance in G1 and G2. Isokinetic assessment showed a greater muscle deficit in the extensors in both groups. After isokinetic rehabilitation, peak torque for flexors and extensors increased by 21% and 23% respectively, power was 34% and 37% higher, and total work increased by 26% and 47%. On the other hand, the (F/E) ratios were unchanged for all three speeds. In Group 2, peak torque values for flexors and extensors increased by 22 and 15% respectively, power was higher by 31 and 23% and total work was also up by 29 and 17%, while F/E ratios were also unchanged. Group 1 showed the greatest improvement in extensor strength at 60°/s, and in power at 90°/s for the various muscles. CONCLUSION: In our study, we concluded that endurance and muscular strength improved the most after isokinetic rehabilitation.

Validation of Tunisian Arabic version of Pittsburgh Sleep Quality Index in non-clinical adolescents.

INTRODUCTION: Sleep quality is a complex phenomenon with quantitative and subjective aspects that vary during adolescence. The prevalence of sleep disorders is not known in Tunisia due to the lack of validated tools. AIM: To translate and validate the questionnaire Pittsburgh Sleep Quality Index (PSQI) into Tunisian Arabic in middle school students. METHODS: We translated the PSQI into Tunisian Arabic based on the translation back-translation method. We conducted a cross-sectional study on a sample of 560 adolescents. Exploratory factor analysis was performed to study construct validity. To test reliability, the global internal consistency of the scale was computed. RESULTS: The construct validity was verified by factor analysis, proving that a single factor explained 30.3% of the overall variance. This model produced a good factor load for all the components. The analysis of the reliability showed an acceptable internal consistency (Cronbach's alpha=0.6). CONCLUSION: The Arabic Tunisian version of the PSQI is a psychometrically valid measure. The PSQI could be useful for the detection and evaluation of symptoms of sleep disorders, as well as for further studies and researches about associated factors with poor sleep quality in adolescent and youth.

Evaluation of Tunisian wheat endophytes as plant growth promoting bacteria and biological control agents against Fusarium culmorum.

Plant growth-promoting rhizobacteria (PGPR) applications have emerged as an ideal substitute for synthetic chemicals by their ability to improve plant nutrition and resistance against pathogens. In this study, we isolated fourteen root endophytes from healthy wheat roots cultivated in Tunisia. The isolates were identified based from their 16S rRNA gene sequences. They belonged to Bacillota and Pseudomonadota taxa. Fourteen strains were tested for their growth-promoting and defense-eliciting potentials on durum wheat under greenhouse conditions, and for their in vitro biocontrol power against Fusarium culmorum, an ascomycete responsible for seedling blight, foot and root rot, and head blight diseases of wheat. We found that all the strains improved shoot and/or root biomass accumulation, with Bacillus mojavensis, Paenibacillus peoriae and Variovorax paradoxus showing the strongest promoting effects. These physiological effects were correlated with the plant growth-promoting traits of the bacterial endophytes, which produced indole-related compounds, ammonia, and hydrogen cyanide (HCN), and solubilized phosphate and zinc. Likewise, plant defense accumulations were modulated lastingly and systematically in roots and leaves by all the strains. Testing in vitro antagonism against F. culmorum revealed an inhibition activity exceeding 40% for five strains: Bacillus cereus, Paenibacillus peoriae, Paenibacillus polymyxa, Pantoae agglomerans, and Pseudomonas aeruginosa. These strains exhibited significant inhibitory effects on F. culmorum mycelia growth, sporulation, and/or macroconidia germination. P. peoriae performed best, with total inhibition of sporulation and macroconidia germination. These finding highlight the effectiveness of root bacterial endophytes in promoting plant growth and resistance, and in controlling phytopathogens such as F. culmorum. This is the first report identifying 14 bacterial candidates as potential agents for the control of F. culmorum, of which Paenibacillus peoriae and/or its intracellular metabolites have potential for development as biopesticides.

Knowledge, attitudes and practices of sheep owners regarding abortion in Northern Tunisia.

BACKGROUND: Abortion in ewes causes high economic losses and represents a threat for human health due to abortive zoonotic pathogens. OBJECTIVE: The present study aimed to assess the knowledge, attitudes and practices (KAP) among sheep owners in the northern Tunisia regarding ewes' abortions. METHODS: Between February 2021 and May 2022, a structured questionnaire containing both close and open-ended questions was applied to 120 sheep owners in northern Tunisia. The data collected were analysed by chi-square test using Epi info 6 software. RESULTS: The majority (75%) of participants reported a history of abortion in their sheep flocks. Sheep owners thought that the most frequent cause of abortion was physical factors, such as trauma, climate and stress (60% ± 5.5%; 48/80), followed by toxicity (15% ± 4%; 12/80), metabolic and nutritional conditions (12.5% ± 3.7%; 10/80), vaccination (5% ± 2.4%; 4/80) and infectious causes (7.5% ± 2.9%; 6/80) (p < 0.001). The majority of animal owners reported that abortions occurred mainly during autumn (39.6% ± 5%; 38/96), followed by summer (27% ± 4.5%; 26/96), winter (23% ± 4.3%; 22/96) and spring (10.4% ± 3.1%; 10/96) (p < 0.001). Approximately, half (45.8% ± 5%; 55/120) of interviewed farmers would not take any action if an abortion occurred. Half of the interviewed farmers (50.5% ± 5.1%; 48/95) did not apply any preventive measures when manipulating aborted ewes, and most of the sheep owners (77.3% ± 3.8%; 92/119) did not know that aborted ewes could transmit zoonotic pathogens. CONCLUSIONS: Our survey concluded that sheep owners in Northern Tunisia had poor knowledge and attitudes as well as applied limited actions concerning several health aspects related to abortion. Education programmes should be established in order to improve Tunisian sheep owners' KAP regarding abortion.

Predictive Factors for Successful Smoking Cessation in Tunisian Smokers, Sousse-Tunisia: 2015-2020.

OBJECTIVE: Since 2009, the unit of smoking cessation at Sahloul University Hospital - Tunisia was founded. In this context, the objective of our study was to determine the factors associated with smoking cessation in Tunisian smokers. METHODS: It was a descriptive prospective study over five-years-period 2015-2020. We included all patients who willingly came to the anti-smoking consultation of the Sahloul University hospital Sousse Tunisia. Data were collected during the consultation of all patients. We proceeded to a univariate and then multivariable analysis to identify the predictive factors of smoking cessation. RESULTS: Over 5 years, we included 450 patients, mainly males (91.3%). The average age of the consultants was 46 ±15.58 years. The average age of the first cigarette among our patients was 16.83± 4.34 years. The likelihood of smoking cessation was higher among males (p=0.004, OR=9.708), patients attending minimum 3 anti-smoking consultations (p<10-3, OR=5.714), patients benefiting from nicotine replacement therapy (p=0.034, OR=2.123), with high motivation score for smoking cessation (p=0.001, OR=1.980) and with an advanced age of the first cigarette (p<10-3, OR=1.096). However, the likelihood of smoking cessation was lower among coffee and alcohol consumers (p=0.002, OR=0.252) and smokers with less than 5 years smoking habit (p=0.011, OR=0.069). CONCLUSION: Although the decision to stop smoking is a personal one, it requires medical and psychological support as highlighted by our findings. Our study showed that assiduity and medical assistance for tobacco cessation increase smokers' chances of quitting.

Consanguinty and its impact on health and genome dynamic: An example from Tunisia.

The genetic disease spectrum in Tunisia arises from the founder effect, genetic drift, selection, and consanguinity. The latter represents a deviation from panmixia, characterized by a non-random matrimonial choice that may be subject to several rules, such as socio-cultural, economic, or other factors. This shifts the genetic structure away from the Hardy-Weinberg equilibrium, increasing homozygous genotypes and decreasing heterozygotes, thus raising the frequency of autosomal recessive diseases. Similar to other Arab populations, Tunisia displays high consanguinity rates that vary geographically. Approximately 60% of reported diseases in Tunisia are autosomal recessive, with consanguinity possibly occurring in 80% of families for a specific disease. In inbred populations, consanguinity amplifies autosomal recessive disease risk, yet it does not influence autosomal dominant disease likelihood but rather impacts its phenotype. Consanguinity is also suggested to be a major factor in the homozygosity of deleterious variants leading to comorbid expression. At the genome level, inbred individuals inherit homozygous mutations and adjacent genomic regions known as runs of homozygosity (ROHs). Short ROHs indicate distant inbreeding, while long ROHs refer to recent inbreeding. ROHs are distributed rather irregularly across the genome, with certain short regions featuring an excess of ROH, known as ROH islands. In this review, we discuss consanguinity's impact on population health and genome dynamics, using Tunisia as a model.
