Incidence and risk factors of post COVID-19 syndrome: a Tunisian cohort study. BMC Infect Dis 2024; 24:461. [PMID: 38693500 PMCID: PMC11064346 DOI: 10.1186/s12879-023-08949-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Accepted: 12/24/2023] [Indexed: 05/03/2024] Open
Abstract
BACKGROUND It has become increasingly clear that SARS-CoV-2 infection can lead to persistent physical and mental health problems lasting weeks or months, requiring prolonged periods of clinical care and increasing the burden on the healthcare system. This phenomenon, known as post COVID-19 syndrome (PCS), is a relatively new condition, its incidence is still unclear and differs between studies. OBJECTIVES In this cohort study, we aimed to estimate the incidence of PCS and to identify its risk factors in the Tunisian population. METHODS This is a prospective cohort study that enrolled patients diagnosed with COVID-19 from the triage unit of the University Hospital of Monastir, Tunisia. between April 2021 and June 2022. Patients were contacted by phone for a follow-up evaluation of PCS 12- weeks after the diagnosis date. RESULTS A total of 1451 individuals diagnosed with COVID-19 during the study period, responded to the follow-up evaluation after 3 months. The incidence of PCS was found to be 44.03% (95% CI [41.47; 46.58]), with fatigue being the most common symptom (21.5%), followed by cognitive impairment (10.3%), including memory loss and difficulty concentrating. Multivariate analysis revealed that the main associated factors to PCS were female gender (RR = 1.54; CI95% [1.30 - 1.82]), pre-existing comorbidities (RR = 1.30; CI95% [1.10 - 1.52]), duration of acute COVID-19 illness (days) (RR = 1.02; CI95% [1.01 - 1.03]), hospitalization (RR = 1.27; CI95% [1.05 - 1.53]), number of COVID-19 episodes (RR = 1.46; CI 95% [1.28 - 1.67]) and patients having receive two or more doses of vaccine prior to COVID-19 infection (RR = 0.82; CI95% [0.70 - 0.96]). CONCLUSION Our study allowed to estimate the incidence and identify risk factors of PCS. Recognizing these factors could help to better understand the underlying mechanisms and guide interventions for prevention and management of this condition.

Bullying victimization among adolescents: Prevalence, associated factors and correlation with mental health outcomes. PLoS One 2024; 19:e0299161. [PMID: 38498423 PMCID: PMC10947672 DOI: 10.1371/journal.pone.0299161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Accepted: 02/06/2024] [Indexed: 03/20/2024] Open
Abstract
INTRODUCTION Knowledge of the risk factors of bullying victimization in adolescents is crucial for the implementation of preventive measures. This study aimed to determine the prevalence and associated factors of bullying victimization and to identify its correlation with mental health outcomes among middle school students in Tunisia. METHODS A cross-sectional study was conducted using a multi-stage cluster sampling technique to recruit a sample of 1111 students from 10 middle schools in El kef (Tunisia). The revised Olweus Bully/Victim Questionnaire was used to assess the prevalence and types of bullying victimization and the perceived efforts of others to counteract bullying. The Strengths and Difficulties Questionnaire (SDQ) was used for screening emotional and behavioral problems. Multivariate logistic regression analysis was conducted to determine associated factors of bullying victimization. Additionally, we tested whether emotional and behavioral problems were present for bullying victims. RESULTS The findings reported that 45.8% (95%CI = 45.5-46.0), of the total number of participants experienced school bullying victimization. Multivariate logistic regression analysis, revealed that repeating a grade (OR = 1.82, 95%CI = 1.31-2.54), having a working father (OR = 17.68; 95%CI = 2.29-136,15), and having a working mother (OR = 1.88, 95%CI = 1.39-2.53) were the factors significantly associated with bullying victimization. Nevertheless, a higher mother's educational level (OR = 0.76, 95%CI = 0.67-0.88) was a protective factor against bullying victimization. The self-reported SDQ revealed that the total difficulties score was significantly higher among victims (17.46 ± 5.30 vs. 20.86 ± 5.06, p<0.01). CONCLUSIONS This study showed that the prevalence of bullying in middle schools was high and it significantly led to mental health problems. National policies for bullying prevention within schools are potentially needed. Improving students' problem-solving and soft skills is also essential.

Burden and predictions of hospitalized injuries in a low-middle income country: results from a Tunisian university hospital. Libyan J Med 2023; 18:2266238. [PMID: 37807671 PMCID: PMC10563618 DOI: 10.1080/19932820.2023.2266238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Accepted: 09/29/2023] [Indexed: 10/10/2023] Open
Abstract
Injuries are responsible for a high premature mortality and disability. They are poorly explored in low and middle income-countries. We aimed to estimate the burden of hospitalized injuries in the Monastir governorate (Tunisia) according to the nature of the injury, trends and projections of hospitalizations for injuries up until 2024, and to identify the distribution of this disease burden based on age and sex. We performed a descriptive study from 2002 to 2012 including all hospitalizations for injuries. Data were collected from morbidity and mortality register of the University Hospital of Monastir (Tunisia). We estimated the burden of injuries using the Disability Adjusted Life Years (DALYs). We described injuries (crude prevalence rate (CPR) and age standardized prevalence rate (ASR)), related mortality (lethality and standardized mortality ratio (SMR)), trends and prediction for 2024. A total of 18,632 hospitalizations for injuries representing 10% of all hospitalizations during study period were recorded. Per 1000 inhabitants per year, CPR was 3.36 and the ASR was 3.44. The lethality was of 17.5 deaths per 1000 injured inpatients per year and the SMR was of 2.95 (Confidence Interval of 95%: 2.64-3.29). Burden related to injuries was 2.36 DALYs per 1000 population per year, caused mainly by Years of Life Lost (83.4%), most frequent among men aged under 40 years. The predicted ASR for 2024 was 4.46 (3.81-5.23) per 1000 person-years. Injuries to the head was the most prevalent (20.7%) causing 67.7% of DALYs; and increasing by 226% through 2024. Injuries had a high prevalence and an important burden in a Tunisian university hospital. Prediction showed increased prevalence for 2024. Preventive measures and a trauma surveillance register should be implemented soon.

Abstract
INTRODUCTION Increasing access to healthcare for expectant mothers is a national goal. In Monastir, Tunisia, some Peripheral Maternity Units (PMUs) required assessment. Our goals were to describe the delivery activities in MUs (maternity units) and to assess whether some of PMUs need to have their activities replaced. METHOD We analyzed aggregate data of deliveries in Monastir from 2015 to 2020. The gouvernorate's seven public MUs were included. Only the morning activity was allotted for obstetricians and gynecologists, in RMUs 1 and 2, whereas they were not available in all PMUs. Data was gathered from the reports of the National Perinatal Program. Both the availability of Comprehensive Essential Obstetric Care (CEOC) and Basic Essential Obstetric Care (BEOC) were calculated. Trends were calculated using Joinpoint software. The Annual Percent Change (APC) was calculated. RESULTS The number of births decreased from 2015 to 2020 (APC= -4.3%: 95%CI : -6; -2.4; p = 0.003). The largest significant decreases in APCs of deliveries were reported in PMU 2 (APC = -12.6% (95%CI : -20; -4.4; p = 0.014), in PMU 3 (APC = -29.3% (95%CI : -36.5; -21.4; p = 0.001), and in PMU 4 (APC = -32.9% (95%CI: -49.1; -11.5); p = 0.016). If PMU 3 and 4 were no longer operating as maternity facilities, BEOC and CEOC standards would still be adequat. For accessibility, both PMU 3 and PMU 2 are accessible from PMU 4 and PMU 1, respectively. CONCLUSIONS Pregnant women prefer to give birth in obstetric services with ability to perform emergency caesarean at the expense of PMU. Nowadays, it appears that accessibility is less important than the presence of qualified human resources when a pregnant woman choose a maternity hospital.

The effectiveness of a health education intervention to reduce anxiety in quarantined COVID-19 patients: a randomized controlled trial. BMC Public Health 2023; 23:1188. [PMID: 37340300 DOI: 10.1186/s12889-023-16104-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Accepted: 06/11/2023] [Indexed: 06/22/2023] Open
Abstract
INTRODUCTION The COVID-19 pandemic is regarded as a serious public health concern that boosts levels of stress and anxiety which could be explained by several reasons, including social isolation. In this regard, we aimed to assess the impact of health education on the anxiety level of COVID-19 patients during the isolation period. METHODS This is a randomized controlled trial conducted between February 2021 and June 2021. Patients tested positive for Covid-19 with mild to moderate forms were randomized to Education (n = 267) or control (n = 269). The education group received a phone health education session on day 1 (D1) following the diagnosis. The three components of the health education intervention were an explanation of the coronavirus disease, what to do in the event of complications, and the recommended preventive measures. The two groups received a telephone evaluation of their Hospital Anxiety and Depression scores on D1 and day seven D7 following the positive diagnosis. The primary outcome was the rate of anxiety reduction in each group on D7 based on a HAD-A score ≥ 8. Secondary outcomes were the rate of anxiety reduction on D7 based on a HAD-A score ≥ 11, the percentage of people complying with isolation and the scores of adherences to preventive measures during the isolation in each group. RESULTS Hundred and ninety-six patients in the intervention group and 206 patients in the control group completed the study. The sociodemographic, clinical, and initial anxiety level features of the intervention and control groups were comparable at baseline (p ≥ 0.05). On D7, the education group's anxiety level (HAD-A ≥ 8) decreased from 26 to 16.3% (p = 0.013) while in the control group it increased from 19.4 to 22.8% (p = 0.37). Thus, the percentage change in anxiety between D1 and D7 (delta D7 - D1) was - 9.7% in the Education group and + 3.4% in the Control group. Using the HAD-A ≥ 11 thresholds, the percentage of anxiety decreased from 15.3 to 11.2% (p = 0.26) between D1 and D7, while it increased in the control group from 9.7 to 15.7% (p = 0.045). Thus, the education group's change in anxiety (delta D7 - D1) was - 4.1%, while the control group's change was + 6%. CONCLUSION During an outbreak, providing health education to quarantined patients may be beneficial to reduce the psychological impact of the disease.

Abstract
BACKGROUND Burnout syndrome may affect the safety of frontline healthcare care workers (HCW) and patients. We aimed to measure the prevalence of burnout among HCW in care facilities in Tunisia during the Covid-19 pandemic and to identify its associated factors. METHODS We conducted a cross-sectional study among HCW practicing during the covid-19 pandemic in health care facilities in the governorate of Monastir. Data collection was carried out using an anonymous self-administered questionnaire composed by three sections: epidemiological and clinical characteristics, professional conditions and the Maslach Burn out Inventory (MBI-HSS). RESULTS This study included 371 HCW. The prevalence of burnout was 77.9% (CI 95%: 73.6% - 82.1%). The severe level was found in 71 participants (19.1%), the moderate level in 115 (31%) and the low level in 103 (27.8%). The distribution of the levels of the burnout dimensions among the participants was as follows: high emotional exhaustion (EE) (57.4%), high depersonalization (DP) (39.4%) and low personal accomplishment (22.6%). The main determinants of burnout among healthcare professionals during COVID 19 pandemic were: working more than 6 hours per day (OR = 1.19; CI95% [1.06; 1.34]), physician function (OR = 1.17; CI 95% [1.05; 1.31]), feeling a negative impact of work on family life (OR = 1.40; 95% CI [1.13; 1.73]), and high personal estimation of COVID 19 exposure (OR = 1.15; CI95% [1.02; 1.29]). CONCLUSION During the COVID19 pandemic, the prevalence of burnout among health professionals was high. It was related to hard implication in COVID 19 management. Interventions like adjusting working hours, reducing workload, and providing psychological support should be taken.

Abstract
Abstract
Background
Ventilator-Associated Pneumonia (VAP) continues to cause significant morbidity, mortality, and hospital costs, especially in the intensive care unit (ICU). This study aimed to determine incidence and factors associated with VAP in six ICUs of the University Hospital-Sahloul (Sousse, Tunisia) in 2018.
Methods
We conducted a prospective observational cohort study over a three months period in six ICUs of the University Hospital-Sahloul (Sousse, Tunisia) in 2018. All patients hospitalized with mechanical ventilation (MV) for more than 48 hours in the ICUs were included. Logistic regression with the stepwise method of Hosmer and Lemeshow was used to identify factors associated with VAP.
Results
Overall, 110 patients were enrolled. The mean age of patients was 44 ± 25 years. Of them, 66.4% were male. The median duration of MV was 5 days [2-16]. The incidence of VAP was 32% and the density incidence was 33/1000 ventilator days. The most common organism were Pseudomonas aeruginosa (n = 14). Of them, 12 were ceftazidime-resistant and thee were resistant to imipenem. Independent risk factors associated with VAP in ICU were history of antibiotic therapy during last 6 months (p = 0.007), tracheotomy (p < 0.001) and reintubation (p < 0.001).
Conclusions
VAP rates in our ICUs were very high. Antimicrobial stewardship programs involving pharmacists and physicians must be elaborated to optimize the antibiotic prescribing. Mechanical ventilation require more-effective interventions control in our hospital.
Key messages
Ventilator-Associated Pneumonia rates were very high. Independent risk factors associated with Ventilator-Associated Pneumonia were history of antibiotic therapy during last 6 months, tracheotomy and reintubation.

Abstract
We report results from a study of Lambda(0) polarization in the exclusive reaction pp --> p(f)(Lambda0K+) at 800-GeV/c. We observe a dependence of the polarization on the Lambda0K+ invariant mass with large (+71%) positive polarization at small mass (1.63-GeV/c(2)) and large (-43%) negative polarization at large mass (2.75-GeV/c(2)). This observation confirms the result of the CERN ISR R608 experiment and extends the range over which the effect is observed. The strong dependence of the polarization on the Lambda0K+ invariant mass suggests that the origin of the polarization is closely related to the production dynamics of the diffractively produced Lambda0K+ system.

Abstract
A retrospective study of 1006 patients was undertaken to evaluate the benefit of a change of strategy in performing coronary artery by-pass grafting surgery. Group A consisted of 500 patients who were consecutively operated on cardiopulmonary by-pass and group B consisted of 506 patients who were consecutively operated on using "off pump" techniques. Pre-operative risk profile in both groups were similar as was as in the operating time. There was distinct benefit in amount of homologous transfusion, period of ICU stay, increased usage of radial artery conduit and improvement in transoesophageal echocardiography assessment of ischaemic mitral incompetence immediately after revascularisation in off pump (group B). Though there was a lower mortality in group B ie, 3/506 vis-a-vis 10/500 in group A this is not of statistical significance. Improvement in left ventricular ejection fraction >5.0% occurred more frequently in one month follow-up visits of group B patients. Period of return to active life was also shorter (28 versus 56 days). Based on observations, we conclude that there is a distinct benefit in avoiding cardiopulmonary by-pass while performing coronary artery by-pass grafting.

Abstract
In Hungary the use of angiotensin converting enzyme inhibitor enalapril has emerged as one of the most important drugs in the treatment of hypertension. The aim of our study was to evaluate the antihypertensive effect of enalapril of Hungarian production in combination therapy and alone, according to sexes, to the body mass index, among smokers and non smokers as well as non diabetic and in patients with diabetes (IDDM and NIDDM). The diurnal blood pressure values were registered by a 24 hour ambulatory blood pressure monitor. During the 6 weeks of the enalapril therapy (n = 28) both the daytime (141/84 vs. 135/80 mmHg) and the night-time (130/78 vs. 124/72 mmHg) blood pressure values decreased; the increase of diurnal indices during the therapy (SI/DI 6/8% vs. 8/10) reflect the 24 hour long lasting effect of the drug. The body mass index had no influence on the efficacy of treatment. Our results indicate that enalapril manufactured in Hungary is an effective antihypertensive drug both in monotherapy and in combination, in both sexes (especially in men), irrespective of the body weight, in non-smokers and especially in smokers, in insulin dependent and in non-insulin dependent diabetes mellitus alike.

Abstract
OBJECTIVE To determine former residents' views of a therapeutic community and factors associated with a good response to therapy. METHOD Retrospective, using a self-report questionnaire. RESULTS Of 51 contactable former residents, 32 completed the questionnaire. Responses were generally very positive, although the best outcome was reported by those who held a social-interpersonal rather than a biological view of psychiatric disorder, and who scored close to normal on a measure of intropunitiveness. Respondents emphasized the crucial role of feedback and confrontation by staff and co-residents in changing their unhelpful behaviour and attitudes, although a few thought that confrontations were too forceful. The mean duration of psychiatric disorder (mainly substance abuse and personality disorder) was more than 4.5 years. Many respondents emphasized the failure of orthodox treatments to help them, adding that their disorders would probably have continued indefinitely without treatment in a therapeutic community.

Abstract
D-Met2,Pro5-enkephalinamide (EA) 10 mg, given SC, induced a dramatic rise in serum prolactin (PRL) and growth hormone (GH) levels in healthy male volunteers. The TSH content was also moderately elevated. Naloxone 0.8 mg administered IV abolished these effects. Bromocriptine 2.5 mg given per os also antagonized EA-induced PRL and TSH release but potentiated the GH surge. Methysergide 2.0 mg administered orally partially reversed EA-elicited PRL release, further augmented GH liberation and did not modify TSH output. The data indicate that inhibition of the dopaminergic tone and/or activation of certain serotonergic mechanisms play an important role in the EA-induced release of PRL and TSH. However, primarily other neurotransmitters might mediate the GH liberation elicited by this opioid peptide.

Abstract
As reported previously D-Met2,Pro5-enkephalinamide (EA) is a highly active enkephalin analogue. To examine its human tolerability male volunteers were treated s.c. with increasing doses (0.1-30.0 mg). The observed autonomic effects were as follows: feeling of heaviness in the limbs, dry mouth, pallor of the face and conjunctival injection. There was no significant change in blood pressure, pulse and respiratory frequency. The autonomic effects appeared within 15-30 min. However, its effects on mood and wakefulness i.e. slight drowsiness, decrease in psychic tension and emotional detachment developed only later. The serum prolactin level increased dose-dependently, while the growth hormone (HGH) content showed biphasic dose-response pattern. The TSH content increased only at the highest doses applied (10.0-30.0 mg).
