Predictors of assertive behaviors among a sample of first-year Tunisian medical students.

Assertiveness is a constructive interpersonal behavior alternative to manipulation and aggression. Medical students (MSs) have daily interpersonal interactions with colleagues, patients and families. Yet, communication deficiencies due to hesitancy to speak-up assertively lead to adverse patient outcomes. This study aimed to assess levels of assertive behaviors (ABs), and to determine its predictors within a sample of first-year Tunisian MSs. This was a cross-sectional survey including 125 first-year MSs from Tunisia. ABs were measured by the Rathus assertiveness scale. Potential independent predictors of AB were evaluated using the following questionnaires: Rosenberg self-esteem scale, interpersonal communication skills inventory short-form-36quality of life questionnaire, and general health questionnaire. In addition, some MSs' characteristics were considered (eg; age, sex, living with family, assertiveness training, community work, personal medical field choice, smoking, and alcohol use). Univariate and multivariate analyses were performed. Among the 309 MSs, 125 (40.45%) responded to the survey. AB were found in 36.8% of MSs. Multiple linear regression models revealed that self-esteem global scores, sending clear messages, anxiety/depression and male sex were accountable for 31% in AB scores variance. Targeting self-esteem and interpersonal communication skills (sending clear messages) and identifying subgroups of students with anxiety/depression state would influence ABs.

Mental Health during COVID-19 Pandemic: The Role of Optimism and Emotional Regulation.

In light of different challenges associated with the COVID-19 pandemic, university students are considered a particularly vulnerable population to mental health and study engagement issues. The first years at university represent a crucial period for students and are associated with an increase in mental health problems, particularly in healthcare studies. This study aimed (1) to document the current levels of mental health and study engagement among healthcare students in Tunisia, and (2) to investigate the relationships between emotional regulation, optimism, study engagement and common mental health problems (stress, anxiety and depression) among this population. A cross-sectional, electronic survey-based research design was used to draw a sample of 366 health care students from a University in Tunisia. Participants mostly reported mild (34.7%) or moderate (44.3%) levels of depression, moderate (44.7%) or severe (33.6%) levels of anxiety, average (50.8%) or mild (33.8%) levels of stress, and high levels of study engagement (>85%). Through structural equation modelling, the results showed that emotional regulation negatively affected stress, anxiety, and depression. Optimism partially mediated the relationship between emotional regulation, anxiety and depression and fully mediated the relationship between emotional regulation and study engagement. The findings indicated a high prevalence of psychological distress among healthcare university students in Tunisia, and specific protective factors that may be targeted to reduce mental health problems.

Effectiveness of an online positive psychology intervention among Tunisian healthcare students on mental health and study engagement during the Covid-19 pandemic.

Research indicates that university students present higher levels of psychological distress compared with non-student age-matched youth. These levels are higher among healthcare students, and even higher during the Covid-19 pandemic. Therefore, cost-effective large-scale interventions are needed in order to prevent further development of psychological distress during this period, and more generally. The aim of the current study was to assess the effectiveness of an 8-week Internet-based positive psychology intervention for healthcare students in Tunisia. A two-armed randomized controlled trial was conducted among a sample of 366 health care students (183 in the experimental group and 183 in the control group), with a majority of women (94%). The average age was 20.74 years (±1.64). The participants completed the following online questionnaires at three time-points (before the program, immediately after, and three months later): stress, anxiety, depression, emotional regulation, optimism, hope, study engagement, and well-being. Repeated-measures ANOVAs revealed significant positive effects of the intervention on all the measured variables for the experimental group. The results showed a significant improvement immediately after the intervention compared to the control group, which was maintained three months later. This program may thus be considered as a promising means of improving students' mental health and study engagement.

Heterogeneity of Psychosis Risk Within Individuals at Clinical High Risk: A Meta-analytical Stratification.

IMPORTANCE: Individuals can be classified as being at clinical high risk (CHR) for psychosis if they meet at least one of the ultra-high-risk (UHR) inclusion criteria (brief limited intermittent psychotic symptoms [BLIPS] and/or attenuated psychotic symptoms [APS] and/or genetic risk and deterioration syndrome [GRD]) and/or basic symptoms [BS]. The meta-analytical risk of psychosis of these different subgroups is still unknown. OBJECTIVE: To compare the risk of psychosis in CHR individuals who met at least one of the major inclusion criteria and in individuals not at CHR for psychosis (CHR-). DATA SOURCES: Electronic databases (Web of Science, MEDLINE, Scopus) were searched until June 18, 2015, along with investigation of citations of previous publications and a manual search of the reference lists of retrieved articles. STUDY SELECTION: We included original follow-up studies of CHR individuals who reported the risk of psychosis classified according to the presence of any BLIPS, APS and GRD, APS alone, GRD alone, BS, and CHR-. DATA EXTRACTION AND SYNTHESIS: Independent extraction by multiple observers and random-effects meta-analysis of proportions. Moderators were tested with meta-regression analyses (Bonferroni corrected). Heterogeneity was assessed with the I2 index. Sensitivity analyses tested robustness of results. Publication biases were assessed with funnel plots and the Egger test. MAIN OUTCOMES AND MEASURES: The proportion of each subgroup with any psychotic disorder at 6, 12, 24, 36, and 48 or more months of follow-up. RESULTS: Thirty-three independent studies comprising up to 4227 individuals were included. The meta-analytical proportion of individuals meeting each UHR subgroup at intake was: 0.85 APS (95%CI, 0.79-0.90), 0.1 BLIPS (95%CI, 0.06-0.14), and 0.05 GRD (95%CI, 0.03-0.07). There were no significant differences in psychosis risk at any time point between the APS and GRD and the APS-alone subgroups. There was a higher risk of psychosis in the any BLIPS greater than APS greater than GRD-alone subgroups at 24, 36, and 48 or more months of follow-up. There was no evidence that the GRD subgroup has a higher risk of psychosis than the CHR- subgroup. There were too few BS or BS and UHR studies to allow robust conclusions. CONCLUSIONS AND RELEVANCE: There is meta-analytical evidence that BLIPS represents separate risk subgroup compared with the APS. The GRD subgroup is infrequent and not associated with an increased risk of psychosis. Future studies are advised to stratify their findings across these different subgroups. The CHR guidelines should be updated to reflect these differences.

Validation of the Arabic version of the Comprehensive Assessment of At Risk Mental States (CAARMS) in Tunisian adolescents and young adults.

AIM: The study aimed to examine whether the Arabic version of the Comprehensive Assessment of At Risk Mental States (CAARMS) has good construct validity, concurrent validity and reliability. METHODS: Validity was established on a sample of 58 Tunisian adolescents and young adults aged between 16 and 30 years. These subjects were divided into three groups according to the CAARMS scores: ultra-high risk positive subjects (UHR (+) ) (n = 22), ultra-high risk negative subjects (UHR (-) ) (n = 25) and subjects meeting the criteria of a first-episode psychosis (FEP) (n = 11). For construct validity, we used the convergent validity. We used the Positive and Negative Syndrome Scale (PANSS) concomitantly with the CAARMS. For concurrent validity, we studied the correlation between symptoms of the CAARMS and their equivalents in the PANSS. The CAARMS reliability was conducted by the study of interrater reliability. RESULTS: The UHR (+) group was shown with intermediate scores of PANSS between the two groups UHR (-) and FEP. That confirms a good construct validity of the Arabic version of the CAARMS. We noted a correlation between the scores in positive and negative sections measured by the CAARMS and their corresponding level of the PANSS. These results show that the CAARMS has a good concurrent validity with the PANSS. For the reliability study, we noted a good correlation between the two raters with a Pearson coefficient ranging from 0.55 to 0.90. CONCLUSION: Analysis of the results of construct validity, concurrent validity and reliability of the CAARMS indicates that this version translated into Arabic is valid and reliable.

TULUP (TUnisian LUPus): a multicentric study of systemic lupus erythematosus in Tunisia.

AIM: Clinical features of systemic lupus erythematosus (SLE) have been described from different geographical regions around the world. However, data from North African countries, including Tunisia, are scarce. METHODS: The aim of this retrospective multicenter study was to analyze demographic, clinical, laboratory features and outcome of SLE in Tunisia throughout 14 Departments of Internal Medicine and to compare them with those of other ethnic and geographic groups. RESULTS: Seven hundred and forty-nine cases of SLE were recorded (American College of Rheumatology criteria) during a 17-year period (1989-2006). They were 676 women and 73 men with an average age at SLE onset of approximately 30.66 years. Our Tunisian patients were characterized by a high frequency of photosensitivity (67.6%), malar rash (68.7%), renal involvement (49.5%) and anti-Sm antibodies (44.8%). Infections were the main complications. Fifty-six (7.5%) patients died during the study period. CONCLUSION: Potential limitations and biases in our study need discussion. Specific recruitment of patients in tertiary referral centers may be the source of selection bias and adding to the frequency of moderate or even severe diseases. The therapeutic management and outcome monitoring were heterogeneous due to the fact that patients were evaluated by different doctors. However, this study remains the most representative of Tunisian SLE patients recruited from all parts of Tunisia.

Characteristics of neurological manifestations of Behçet's disease: a retrospective monocentric study in Tunisia.

OBJECTIVE: The aim of the present study was to analyze demographic, clinical and genetic features of Behçet's disease patients with neurological involvement through a monocentric study of a homogenous group of hospitalized patients observed in the same department and to compare them with those of other ethnic and geographic groups. METHODS: Four hundred and thirty Behçet's disease (BD) patients were retrospectively studied. Diagnosis of BD was made according to the international study group for Behçet's disease criteria. Patients with neurological findings suggestive of involvement of the nervous system by BD were further studied according to clinical examination, laboratory tests and neuroradiological investigations. RESULTS: Neurological involvement was observed in 121 patients (28.1%). The mean age at neuro-Behçet's disease (NBD) onset was 29.7 years. Average disease duration of BD before neurological manifestations onset was 6.4 years. Male to female ratio was 1.8. Of the 121 NBD patients, parenchymal involvement occurred in 74 patients (61%). Among them 26 (21.4%) presented with brainstem involvement, 24 (19.8%) with hemispheric involvement and 2 (1.6%) with spinal cord involvement. Non-parenchymal NBD occurred in 47 patients (39%). Involvement of the main vascular structures (Vasculo-NBD) was the most common non-parenchymal NBD lesion found in 35 patients (28.9%) consisting of cerebral vein thrombosis (CVT) in 24 cases and cerebral arterial thrombosis in 11 cases. Forty-nine (40.5%) patients with NBD have been followed-up for a median of 3 years (range 1-19 years). Forty-one of them recovered well without significant residual disability, 5 patients made no improvement and are left with severe neurological impairments and 3 died. Male gender and CNS parenchymal lesions occurrence were significantly associated with a poorer prognosis. CONCLUSION: Clinical and epidemiological features of NBD are various. In our Tunisian cohort of NBD patients the main characteristic features were male predominance, a relatively high prevalence of CVT, a low prevalence of intra-cranial hypertension and a significant lower frequency of HLA-B51 haplotype.

[Benzylthiouracil induced ANCA-positive vasculitis]. / Vascularite à anticorps anticytoplasme de polynucléaires neutrophiles induite par le benzylthio-uracile.

INTRODUCTION: Several cases of vasculitis associated with antineutrophil cytoplasmic antibodies (ANCA) have been reported in patients treated with synthetic anti-thyroid drugs but only 2 cases have incriminated benzylthiouracil. OBSERVATION: A 36 year-old woman, 3 years after treatment with benzylthiouracil, rapidly developed progressive kidney failure, related to a pauci-immune extra-capillary glomerular nephropathy and necrotic vasculitis lesions. The search for p-ANCA was positive with anti-myeloperoxidase specificity. She was treated with corticosteroids and 6 monthly intravenous pulses of cyclophosphamide substituted by azathioprine. Renal failure and proteinuria significantly improved. However the high level of p-ANCA. CONCLUSION: ANCA vascularities are a rare but serious complication of treatment with synthetic thiouracile-type anti-thyroid drugs. The ANCA must be measured when confronted with a systemic manifestation during treatment.

Association of right heart thrombosis, endomyocardial fibrosis, and pulmonary artery aneurysm in Behçet's disease.

A 29-year-old man with a 5-year history of Behçet's disease was admitted for fever, dyspnae, chest pain, and hemoptysis. A diagnosis of right ventricle and atrial thrombosis associated with a pulmonary artery aneurysm was made. The patient was treated with anticoagulants and prednisone. Since hemoptysis persisted, surgical excision of the intracardiac thrombosis was performed and histological findings were consistent with organizing thrombus and endomyocardial fibrosis. Transesophageal echocardiography 6 months later showed recurrence of the right ventricle thrombosis. A course of 6-monthly boluses of intravenous cyclophosphamide was begun. Currently, at 2 years of follow-up, the patient is asymptomatic.

Esophageal involvement in Behcet's disease.

Esophageal involvement in Behcet's disease is very rare, and normally is observed as aphtosis and esophagitis, but serious complications such as erosions, perforations, and stenosis may occur. We carried out this prospective study to evaluate the prevalence of esophageal involvement in Behcet's disease and to establish if routine endoscopy and/or manometry are necessary. Twenty-three patients who fulfilled the diagnostic criteria of the international study group for Behcet's disease were enrolled. None were taking drugs or had disease that might produce esophageal abnormalities or alter any existing changes due to the Behcet's disease itself. Twenty- three patients underwent esophagogastroduodenoscopy by a single observer. Esophageal biopsies were performed in thirteen patients and esophageal manometry in twenty. At the beginning of the study, the disease activity was defined by the presence of more than one symptom related to Behcet's disease, and upon the classification of Behcet's disease. Of the twenty three patients enrolled two were excluded from final analysis because of the presence of hiatus hernia. Thus, 13 men and 8 women, ranging in age from 20 to 63 years with a mean age of 36.2 years were included. Ten patients (47.6%) had active disease and four (19%) complained of upper gastrointestinal symptoms at the time of the study. Fourteen patients had endoscopic, manometric and/or microscopic abnormalities. Esophageal manometry was performed in twenty patients and was abnormal in 7 cases (35%). Esophageal biopsies were done in 13 patients and revealed histopathological abnormalities in 5 cases. Microscopic findings showed vasculities in one case, and non-specific inflammatory infiltration mainly consisting of neutrophils in 4 cases. Our results suggest that the prevalence of esophageal involvement in Behcet's disease is rather high and occur even in asymptomatic patients, but that this usually does not result in specific abnormalities.
