Determination of the Contributing Factors and HbA1c Cutoff Leading to Glucose Tolerance Abnormalities Following Gestational Diabetes.

The prevalence of gestational diabetes mellitus (GDM) has been steadily increasing over the past years. It is a major risk factor for glucose intolerance and type 2 DM (T2DM). The American Diabetes Association recommends that women whose pregnancy was complicated by GDM be screened for persistent glucose abnormalities at six to 12 weeks postpartum with either a fasting plasma glucose test alone or with a fasting 75-g, two-hour oral glucose tolerance test. This study aimed to identify the main predictive factors of glucose tolerance disorders in early postpartum women with a recent history of GDM. In this retrospective descriptive study, we identified 400 women who met the eligibility criteria for the study. The mean age was 34.54 ± 5.51 years. A total of 70% had a family history of DM, 16% had a personal history of GDM, and 23% had fetal macrosomia in previous pregnancies. The overall incidence of postpartum carbohydrate tolerance disorders was 36.4%, including 12% prediabetes and 24.4% DM. The prevalence of prediabetes and T2DM after delivery was higher with older maternal age, multigravidity, a higher BMI, a history of GDM, and fetal macrosomia in previous pregnancies. Furthermore, the persistence of this impaired glucose tolerance in postpartum was associated with a higher term of diagnosis, a higher glycated hemoglobin (HbA1c) percentage (the discriminant cutoff value with the best sensitivity/specificity ratio was 5.25%), the use of insulin therapy, cesarean section delivery, and fetal macrosomia. After adjusting for confounders, only prior GDM, a higher HbA1c level, macrosomia, and gestational term were found to significantly affect postpartum glucose tolerance. Although postpartum screening for T2DM is recommended for all women with GDM, a significant number of patients fail it. A better knowledge of predictive factors for this outcome is therefore needed for a more effective and targeted medical intervention.

Weight excess among high-school students: Relation with mental health and sociodemographic factors.

INTRODUCTION: The escalating prevalence of adolescent obesity represents a complex public health challenge, influenced by interactions of environmental, socio-economic, and behavioral factors. Recent studies reveal a surge in addictive substance use among adolescents, with non-substance addictions. Overweight adolescents are particularly susceptible to risky behaviors. Tunisia is not exempt from this issue, facing a rapidly increasing prevalence. AIM: Our work aimed to assess the prevalence of obesity among adolescents and to explore the connections between sociodemographic factors, mental health, and overweight in this demographic group. METHODS: A cross-sectional study was led among sample of Tunisian high school adolescents from Sousse. We enrolled study participants through proportional stratified sampling. RESULTS: Our study included 1399students, predominantly female, with an average age of 17±1.5 years. The average BMI (Body Mass Index) was 22.7±4.1 kg/m². According to the International Obesity Task Force (IOTF), 20.4% were overweight, and 7% were obese, resulting in an overall weight excess prevalence of 27.4%. Girls exhibited a higher weight excess prevalence compared to boys. Multivariate analysis identified factors associated with overweight and obesity, including maternal self-employment(aOR=2.13,[1.35-3.35];p<0.001), regular physical activity (aOR=0.61,[0.47-0.8];p<0.001), internet usage ≥2 hours (aOR=0.70,[0.50-0.99];p=0.045), daily fruit-vegetable consumption (aOR=1.51,[1.15-1.97]; p=0.003), possible alexithymia (aOR=1.55,[1.07-2.22];p=0.018), probable anxiety (aOR=1.28,[0.87-1.89]; p=0.007), very probable anxiety (aOR=1.61,[1.14-2.2]; p=0.037), and problematic Facebook-use (aOR=0.67,[0.50-0.89]; p=0.006). CONCLUSION: Understanding factors tied to excess weight in our social and cultural context is crucial in shaping effective public health strategies. Interventions should adopt a multisectoral approach specifically targeting working mothers within the adolescent's socio-familial environment. It is fundamental also to address mental health concerns, with a particular focus on alexithymia and anxiety.

Safety and efficiency of COVID-19 vaccine in North Africa.

Background In the absence of a specific treatment for COVID-19, preventive measures have been implemented to control this pandemic and vaccination is one of them. However, it is crucial to verify the safety and efficiency of every vaccine. The aim was to determinate the predictive factors of side effects and reinfection after COVID-19 vaccine. Methods A cross-sectional study was conducted in February 2022 among Tunisians infected with COVID-19 between March 2020 and February 2022, using an online self-administered questionnaire. We conducted univariate and multivariate analyses using binary stepwise logistic regression. Results A total of 1541 was selected from 1911 individuals. Comorbidities affected a quarter of the population (22.3%). Before the initial infection, 39.3% had received full vaccination, and 8.7% had received partial vaccination. By February 2022, the majority (82.9%) had received at least two vaccine doses. The reinfection rate was 30.6%. All vaccines prior to the first infection was identified as a protective factor against reinfection. Inactivated virus vaccinations were less likely to induce adverse effects. Conclusion ach vaccine has its own set of advantages and disadvantages: mRNA-based vaccines had a higher incidence of side effects but all vaccines provided better protection against reinfection.

Complementary and alternative medicine in oncology: knowledge, attitude and practice among Tunisian healthcare workers.

PURPOSE: Over the past years, there has been a considerable increase in complementary and alternative medicine (CAM) use among cancer patients. However, guidance from health care workers (HCWs) is not always provided. We aimed to determine the knowledge, attitude and practice of Tunisian HCWs regarding the use of CAM in cancer patients. METHODS: We conducted a multicenter cross-sectional study over 5 months from February to June 2022 among HCWs caring for cancer patients in the Tunisian center region. Data were collected using a self-administered questionnaire developed by our investigators. RESULTS: The level of knowledge about CAM was declared limited by 78.4% of our population. The best known CAM therapies were herbal medicine and homeopathy while chiropractic and hypnosis where the least. HCWs who had sought information on CAM represented 54.3% of our sample and the main source of information was the Internet (37.1%). A positive attitude towards the use of CAM was found in 56% of HCWs. The integration of CAM into supportive care in oncology was approved by 78% of HCWs. Concerning training on CAM, 78% declared its necessity for HCWs and 73.3% expressed a desire to have it. A personal use of CAM was found in 53% of HCWs while 38.8% had previously used CAM in the treatment of their cancer patients. CONCLUSION: The majority of HCWs had a positive attitude towards the use of CAM in oncology despite their poor knowledge about it. Our study emphasizes the need to train HCWs dealing with cancer patients on CAM.

Symptoms and risk factors for long COVID in Tunisian population.

BACKGROUND: The COVID-19 pandemic has presented various challenges, one of which is the discovery that after the acute episode, around 30% of patients experience persistent symptoms or develop new ones, now known as long COVID. This new disease has significant social and financial impacts. The objective is to determine the prevalence of long COVID in the Tunisian population and identify its predictive factors. METHODS: This was a cross-sectional study conducted among Tunisians who were infected with COVID-19 between March 2020 and February 2022. An online self-administered questionnaire was distributed through social media, radio, and television channels over the course of one month (February 2022). Long COVID was defined as the persistence of existing symptoms or the development of new symptoms within three months after onset, lasting for at least two months, and with no differential diagnosis. We performed univariate and multivariate analyses using binary stepwise logistic regression with a significance level set at 5%. RESULTS: A total of 1911 patients participated in our study, and the prevalence of long COVID was 46.5%. The two most frequent categories were general and neurological post-COVID syndrome, with a prevalence of 36.7% each. The most commonly observed symptoms were fatigue (63.7%) and memory problems (49.1%). In the multivariate analysis, the predictive factors for long COVID were female gender and age of 60 years or older, while complete anti-COVID vaccination was found to be a protective factor. CONCLUSIONS: Our study found that complete vaccination was a protective factor against long COVID, while female gender and age of 60 years or older were identified as the main risk factors. These findings are consistent with studies conducted on other ethnic groups. However, many aspects of long COVID remain unclear, including its underlying mechanisms, the identification of which could guide the development of potential effective treatments.

Fatal falls from great height in Sousse (Tunisia): Study of 141 medicolegal autopsy cases.

INTRODUCTION: Falls from great heights constitute a violent trauma that can lead to death. This represents a suspicious death, leading to initiate legal proceedings with in particular the practice of an autopsy. AIMS: to determine the features of victims of falls from height and relations between medico-legal form of the death, the height of the fall and the nature of traumatic injuries Methods: A retrospective study about 141 cases of death after fall from great height. Data were collected at the Legal Medicine Department of the Farhat Hached University Hospital in Sousse (Tunisia) over a period of 14 years from 2007 to 2020. RESULTS: The average age of the victims was 37±12.8 years with a sex ratio of 6.05. Half of them were day laborers. The majority had no history of psychiatric illness (91.5%). The majority of victims (41.8%) fell from a height of 3 to 6 meters. Regarding injuries, rib fractures (52.4) were predominant, especially on the right side followed by skull fractures (31.2%). A significant difference in the prevalence of rib cage lesions in the groups over 9 meters in height (p<0.05) was found. The lesions of the lower limbs were proportional to the increase in the height of the fall. Deaths were accidental in 80.8% and suicides in 13.5%. CONCLUSION: In cases of high falls, a forensic autopsy is essential to make a complete evaluation of the injuries, to search a correlation between severity of injuries and height of the fall and finally to orientate towards the medico legal form of the fall.

Risk factors of COVID-19 severity among Tunisian patients in the Emergency Department of Sousse, Tunisia.

INTRODUCTION: Despite the spread of COVID-19 in Tunisia and its impact on people, health and economy, few studies have investigated the profile of COVID-19 Tunisian patients. AIM: Determine the epidemiological, clinical, para-clinical and therapeutic characteristics patients and identify the associated factors of severity. METHODS: This is a retrospective study, conducted among confirmed COVID-19 patients consulting the hospital emergency department. We collected Data using from the patients' computerized files. We performed Data entry and analysis using SPSS 22. RESULTS: We included 375 patients. The average age was 66.7±11.43 years with a sex ratio of 1.6. The most frequent comorbidities were diabetes (100%), hypertension (64.5%), and chronic heart disease (25.9%). The most frequent clinical signs were dyspnea (75.2%), asthenia (66.9%), cough (66.7%) and fever (60.3%). The most frequent biological abnormalities were biological inflammatory syndrome (96%) and elevation of troponin (69.3%). CT scans revealed lung damage in 34.1% of patients. As for treatments, 91.7% received antibiotics, 89% received corticosteroids, 89.3% received anticoagulants, and 85.1% received ventilation (42.6% non-invasive ventilation and 1.9% were intubated). Risk factors of severity were age, chronic heart disease and hypertension. CONCLUSION: Knowing the particularities of Tunisian patients will help to install recommendations to improve the process of care and prevention.

Medical students' resilience level and its associated factors: A Tunisian study.

INTRODUCTION: Resilience is one's ability to adapt to internal and external stressors and cope with challenges encountered throughout life. AIM: Our work aimed to determine resilience levels at the Medical University of Ibn El Jazzar-Sousse (Faculty of Medicine of Sousse) Tunisia and to identify the key factors influencing resilience in order to help students improve their college experience, as well as their future career and eventually their quality of life. METHODS: It's a cross-sectional study conducted during October and November 2021 at the FMS including all undergraduate medical students using a questionnaire elaborated in French language and composed of 02 major parts Socio-demographic and general health data and The Connor-Davidson Resilience Scale (CD-RISC). Data were collected using Google Forms platform via social networks (Facebook students' groups). RESULTS: A total of 225 participants filled the questionnaire; the mean age was 21±5 years. Among them 75.1% were females (sex ratio=0.33). The total resilience mean score was 56.36±12.43. Comparison of resilience scores according to different covariates showed that resilience was positively associated with male gender, extracurricular activities, relationships with both colleagues and teachers and physical exercise, but negatively associated with imposed course of study and perception of both study difficulties and personal academic results. No correlation was found between resilience score and age. CONCLUSIONS: This work encourages university administrators to devote more resources to promote resilience, and it emphasizes the importance of implementing new educational and entertaining interventions to improve students' ability to deal with academic challenges.

Patient safety culture in Tunisian maternity care: Analytic study.

INTRODUCTION: Given the potential risks involved in childbirth, patient safety is of utmost importance in maternity care. AIM: To compare the level of patient safety culture between physicians and paramedics in public maternity care structures in Sousse, Tunisia. METHODS: An observational descriptive and cross-sectional study was conducted among health professionals working in all public health maternities of Sousse, Tunisia. A valid Hospital Survey On Patient Safety Culture (HSOPSC) questionnaire was used to gather data, and a score was calculated for each dimension by taking the average of the positive response proportions per item. RESULTS: The global response rate was 86.4%. Paramedics had a higher response rate compared to physicians (90.6% versus 62.1%). The overall scores for the ten dimensions of patient safety culture showed significantly higher scores for physicians compared to paramedics for the dimensions of "Expectations and actions of superiors regarding care safety" and "healthcare professional-patient relationship and safety culture" (88.43% versus 63.73%; p=0.027 and 75.38% versus 65.73%; p=0.041 respectively). Conversely, a significant difference was found in favor of paramedics compared to physicians regarding the dimension of "Management support for care safety" (37.3% versus 13%; p=0.019). CONCLUSION: Significant differences in patient safety culture scores among healthcare professionals. It suggest that efforts should be made to improve management support for care safety for physicians, while paramedics could benefit from increased attention to expectations and actions of superiors regarding care safety and healthcare professional-patient relationship.

Patient safety in medical education: Tunisian students' attitudes.

Health care delivery continues to be unsafe despite major patient safety (PS) improvement efforts over the past decade. Medical school education plays an important role in promoting this culture during initial training. To determine undergraduate medical students' attitudes toward PS at a Tunisian medical school. We carried out a cross-sectional study among undergraduate medical students at Ibn Al Jazzar Medical School in Sousse, Tunisia, using a self-administered questionnaire inspired from the valid tool: Attitudes to Patient Safety Questionnaire (APSQ III). A total of 178 medical students responded to the questionnaire. Medical students tend to have an overall positive perceptions of PS culture with a global mean score 5.33 ± 0.5. Among the individual domains 'Working hours as a cause of error' earned the highest score (6.38 ± 1.0) followed in order by 'Team functioning' (6.24 ± 0.8), 'Error inevitability' (5.91 ± 1.0) and 'Patient involvement in reducing error' (5.50 ± 1.0). The lowest score was for 'Professional incompetence as a cause of error' (4.01 ± 1.0). A PS domain's mean scores comparison based on socio-demographic variables: gender, age, academic year and on PS training revealed a statistically significant difference (p < 0.05) for five PS key dimensions: ' Error reporting confidence ', ' Working hours as a cause of error ', ' Professional incompetence as a cause of error ', ' Team functioning ' and 'PS training received'. Tunisian medical students showed positive attitude towards PS. Nevermore, intensive in terms of frequency and duration sessions, based on various teaching methods may be needed to fulfill students' educational needs.

Hesitation of the Tunisian population to COVID-19 vaccination, and its associated factors.

BACKGROUND: Many people are reluctant to be vaccinated against COVID-19. AIM: To determine the intention to accept COVID19 vaccine and its associated factors among Tunisians. METHODS: We conducted a cross-sectional study among Tunisians from December 2020 to January 2021 using an online questionnaire. Factors associated with intention to accept coronavirus vaccine were analysed using multinomial logistic regression. RESULTS: In total, 169 Tunisians participated in our study. The majority were female (85.2%). The mean age was 48.3 ± 11.8 years. Only 33.1% intended to accept to be vaccinated when COVID-19 vaccine will be available in Tunisia and 22.5% were still hesitant. In multinomial logistic regression, participants having high or very high perceived personal risk of COVID-19 infection (aOR: 3.257, 95% CI : 1.204 - 8.815) were more prone to hesitate to accept COVID-19 vaccine rather than those being willing to accept it. Respondents undergoing seasonal influenza vaccination (aOR: 0.091, 95% CI : 0.019 - 0.433) were less prone to refuse COVID-19 vaccine rather than those being willing to accept it. Young ones aged less than 40 years (aOR: 4.324, 95% CI: 1.180 - 15.843) were more prone to refuse COVID-19 vaccine rather than those being willing to accept it. CONCLUSION: The acceptance rate of coronavirus vaccination was moderate. Therefore, a good communication and health education at a community level are needed.

Epidemiologic patterns of hepatitis A infection during the pre-vaccination era: A population-based survey in Tunisia in 2015.

BACKGROUND: In the 1980s, Tunisia was considered a country of high endemicity for hepatitis A virus (HAV). Since 2000, an epidemiologic shift has led to an increased incidence of symptomatic and severe forms of HAV infection. OBJECTIVES: In 2015, we conducted a cross-sectional nationwide household-based hepatitis A virus (HAV) seroprevalence study in the total population regardless of age, sex, or geographic origin using a stratified sampling design to make an overview of the HAV epidemiologic situation in Tunisia before vaccine implementation. RESULTS: A total of 6,322 individuals were enrolled. The HAV prevalence was 78.8%. The anti-HAV IgG seropositivity rate increased from 16% for ages 5-9 years to 45% for ages 10-14 years, 67% for ages 15-19 years, 87% for ages 20-24 years, and >90% for older age groups, which suggested an age at midpoint of population immunity (AMPI) in late adolescence. It was significantly higher in rural areas (P < 10-3) and varied significantly between and within regions (P < 10-4). CONCLUSIONS: In this study, although the overall AMPI suggestsintermediate endemicity, the regional AMPI varies from intermediate to very high endemicity profiles attributable to different socioeconomic determinants and conditions of sanitation and hygiene. In addition, it provides insights for the best decisions in terms of vaccination strategies.

[Strength of academic motivation among medical students in the Faculty of Medicine of Sousse (Tunisia)].

INTRODUCTION: Motivation is an important component of learning. It remains a complex phenomenon to explore, largely influenced by multiple external and internal factors. It is important to measure the strength of student motivation in a long training course such as medical studies and its influencing factors. AIM: to measure strength of motivation among medical students the Faculty of Medicine of Sousse (FMS). METHODS: It was a cross-sectional study conducted among medical students enrolled at the FMS during the 2021/2022 academic year for 3 months using a questionnaire based on a validated scale: Strength of Motivation for Medical School-Revised (SMMS-R). RESULTS: A total of 185 students participated in the study. The mean age was 20.97 ± 1.8 years. The sex ratio was 0.34. The SMMS-R score was 55[47-63]. This score was higher international students (p=0.029), students who chose medical studies before passing the baccalaureate (p<10-3) and students satisfied with their choice of medical studies (p<10-3). CONCLUSION: Our results revealed a strong association between students' satisfaction and motivation. Thus, the learning environment, governed mainly by institutional rules, educational activities and evaluative practices, greatly influences satisfaction and therefore motivation of medical students.

Hepatitis B birth vaccination, cohort study, Tunisia 2000-2017.

We aimed to compare the efficiency of the first dose of Hepatitis B (HB) vaccine: at Birth versus at 3 months and to evaluate the efficacy of HB vaccine. We conducted a cohort study in the governorate of Monastir. Vaccinated Cohort (VC) included populations receiving the first dose at 3 months (Protocol 1), and at birth (HepB-BD) (Protocol 2). First dose was followed by at least two doses. We collected, from January 2000 to December 2017, cases diagnosed by serological markers (hepatitis B surface antigen (HBsAg) and anti-HBc). We calculated Absolute Risk (AR) per 100,000 PY and the Relative risk reduction (RRR). Twenty-five cases were notified among VC and 1501 cases among not vaccinated cohort (NVC). Twenty-three cases were notified among the cohort receiving the first dose at 3 months and two cases in Protocol 2. The AR per 100,000 PY was 5.67 (CI95%: 3.36-7.99) in Protocol 1 and 0.11 (CI95%: 0.001-0.26) in Protocol 2. The RRR was 77% (95% CI: 66; 85) in Protocol 1 and 99.4% (95% CI: 97.8; 99.9) in Protocol 2. We identified 4 HB cases for children aged between 5 and 11 who benefited from protocol 1 (born between 2000 and 2006) and zero cases for children of the same age group benefiting from protocol 2 (born between 2011 and 2017). The annual number of HB has decreased from 112 in 2000 to 48 in 2017. We predicted 40 new cases of HB in 2030. HepB-BD was 99.4% effective at preventing HB. The continuity of HepB-BD worldwide would achieve WHO's goal of eliminating HB as a threat to health by 2050. ABBREVIATIONS: AR: Absolute Risk; ARR: Absolute Risk Reduction; G1: Group1; G2: Group2; HB: Hepatitis B; HepB-BD: Hepatitis B Birth Dose; MENA: Middle East and North Africa; NNV: Number Needed to Vaccine; HIV: Human Immunodeficiency Virus; NVC: Not Vaccinated Cohort; PY: Person Year; RRR: Relative Risk Reduction; RR: Relative Risk; VC: Vaccinated Cohort; WHO: World Health Organization.

Effectiveness of hand hygiene in an epidemic context. Systematic review.

OBJECTIVE: To assess the effectiveness of Hand Hygiene (HH) in preventing infections and the transmission of pathogens, in an epidemic context, in community and hospital settings. METHOD: It is a systematic review of the literature based on a document request, conducted on PubMed, using the following search equation: "(" Hand Hygiene "[All Fields] OR" Hand Disinfection "[All Fields]) AND ("Epidemics" [All Fields] OR "Pandemics" [All Fields]) ". All publications related to the effectiveness of the preventive intervention for HH in an epidemic setting were Included. RESULTS: A total of 16 publications were included, of which the majority proved the effectiveness of HH and its promotion in reducing infections during an epidemic. In a clinical trial, promoting HH in an intervention group significantly reduced the prevalence of infections (24.4% vs. 11.1%). Two systematic reviews have shown the effectiveness of HH in preventing the transmission of germs with ORs between 0.52 and 0.62. Four case-control studies and three cross-sectional studies concluded with the protective effect of HH with ORs varying between 0.06 and 0.71. A cohort study showed that low adherence to HH recommendations was associated with a higher infection rate (77.5% vs 95%; p = 0.02). A single systematic review did not conclude that HH was effective in the epidemic setting. CONCLUSION: The effectiveness of HH in the fight against epidemics has been demonstrated. It is dependent on the engagement and the active participation of the different intervenient. Hence the need to increase accessibility to different methods of HH and to promote the importance of this prevention strategy could be assured through education and awareness.

Observational study of vaccine effectiveness 20 years after the introduction of universal hepatitis B vaccination in Tunisia.

OBJECTIVES: The objectives of this study were to estimate the national prevalence of hepatitis B infection in Tunisia using data from a nationwide survey, to compare results with those obtained in 1996 survey and to evaluate the impact of vaccination twenty years after its introduction. METHODS: A National household-based cross sectional and serological survey was undertaken in 2015 from randomly selected districts using two-stage sampling. Data collection was performed using standardized and pretested questionnaires and collected blood samples were tested for markers of hepatitis B virus infection. RESULTS: National point prevalence of Hepatitis B surface antigen was 1.7% (95% CI [1.6-1.9%]). The highest prevalence was found in the Center and South regions with respectively 2.3% (95% CI [2.0-2.7%]) and 2.2% (95% CI [1.8-2.8%]). Vaccine effectiveness (VE) was 88.6% (95% CI [81.5-93.0%]) and was higher among population aged less than 20 years 96.1% (95% CI [70.1-99.5%]) than those aged more than 20 years 59.0% (95% CI [32.0-75.3%]). VE was 85.6% (95% CI [65.8-93.9%]) is hyper-endemic areas and 89.1% (95% CI [80.3-94.0%]) in meso-endemic and hypo-endemic areas. CONCLUSIONS: The prevalence of Hepatitis B surface antigen decreased compared to previous estimations and classify Tunisia as a low endemic country as result to the introduction of vaccination since 1995.
