The advancement of nanofluid technology has become an essential tool for investigating thermal conductivity enhancement, which is highly valuable for industrial and engineering applications in many fields including mathematics, physics, engineering, and materials science. This analysis focuses on 3-D boundary-layer flow on nanofluid over a rotating disk by incorporating chemical reaction and thermal radiations effects. One aim of this article is to analyze the energy and mass transport rates for nanofluids. In this study, the Brownian motion and thermophoretic impacts are considered. The governing flow equations are converted to ODE via suitable similarity transformations. The resulting equations were solved via well know technique Keller box method. This analysis revealed that the azimuthal and axial velocities show an inverse pattern against the various values of index factor, n, although the radial velocity has the highest value and decreases significantly. The behavior of the von Karman flow is also recovered for setting the index factor (n = 1). Moreover, it is found that the temperature of nano liquid increases by increasing the Brownian motion and thermophoretic factors. [ABSTRACT FROM AUTHOR]

Objective/background: Viral hepatitis, particularly hepatitis B virus (HBV) and hepatitis C virus (HCV), infections and tuberculosis (TB) are a global public health concern. Co-infection with HBV or HCV among TB patients may potentiate the risk of hepatotoxicity induced by anti-TB drugs. Hence, the aim of this study was to identify the prevalence of HBV and HCV among TB patients included in the Duhok National Tuberculosis Program (NTP). Methods: The Duhok NTP Center is a specialized institution in Duhok City, Iraq, concerned with management and follow-up of TB patients. A cross-sectional study was conducted at the center between June 2015 and May 2016. All documented TB patients were analyzed on the basis of socio-demographic and other characteristics. Thereafter, all patients underwent screening for hepatitis B surface antigen (HBsAg), anti-HCV, and anti-HIV using enzyme-linked immunosorbent assay (ELISA). The results obtained were analyzed by entering the data in binary format into a Microsoft Excel spreadsheet. A p value of

- Abstract
Hypersexuality, also referred to in the literature as sexually inappropriate behavior and sexual disinhibition, involves persistent, uninhibited sexual behaviors directed at oneself or at others. For older adults, the literature generally attributes the behavior to biochemical or physiological changes that accompany cognitive impairment-specifically, dementia. Although less common than other behavioral issues, such as aggression and agitation, hypersexuality presents complex logistical and ethical problems for caregivers. This article reviews the current literature on hypersexual behavior. Assessment essentials as well as nonpharmacological and pharmacological treatment approaches are discussed, identifying the need for standardization as well as caregiver education and training.

The Special Projects Division of the City of Milwaukee Health Department conducted a telephone survey among randomly selected adult residents to determine the population having the greatest potential for benefiting from a health screening a counseling program. A modified version of the Health Hazard Appraisal (HHA) was completed by 268 respondents. From the survey results, it was estimated that by reducing various health risk factors, the respondents could lower their current probability of dying within 10 years by an average of 22 percent. The major predictor of the percentage of reducible risk was age. Persons 18-39 years old could reduce their current probability of dying within 10 years by an average of about 10 percent, whereas persons 40 years and older could reduce theirs by an average of more than 30 percent. Men could lower their probability by slightly more than women, but other sociodemographic factors, such as race, income, education, and residential area, either did not predict significantly the percentage of reducible risk or did so only because of their correlation with age. The results raise questions about the HHA's accuracy in calculating reducible risk, its use of death postponement information to motivate changes in behavior, and its value in health promotion programs, particularly for young adults who are not likely to die of chronic diseases within 10 years. The HHA should only be considered for public health screening programs that target middle-aged and, perhaps, elderly populations rather than the general population of persons under 40 years old.

Abstract Introduction Following twenty years of economic and social growth, Liberia's fourteen-year civil war destroyed its health system, with most of the health workforce leaving the country. Following the inauguration of the Sirleaf administration in 2006, the Ministry of Health & Social Welfare (MOHSW) has focused on rebuilding, with an emphasis on increasing the size and capacity of its human resources for health (HRH). Given resource constraints and the high maternal and neonatal mortality rates, MOHSW concentrated on its largest cadre of health workers: nurses. Case description Based on results from a post-war rapid assessment of health workers, facilities and community access, MOHSW developed the Emergency Human Resources (HR) Plan for 2007-2011. MOHSW established a central HR Unit and county-level HR officers and prioritized nursing cadres in order to quickly increase workforce numbers, improve equitable distribution of workers and enhance performance. Strategies included increasing and standardizing salaries to attract workers and prevent outflow to the private sector; mobilizing donor funds to improve management capacity and fund incentive packages in order to retain staff in hard to reach areas; reopening training institutions and providing scholarships to increase the pool of available workers. Discussion and evaluation MOHSW has increased the total number of clinical health workers from 1396 in 1998 to 4653 in 2010, 3394 of which are nurses and midwives. From 2006 to 2010, the number of nurses has more than doubled. Certified midwives and nurse aides also increased by 28% and 31% respectively. In 2010, the percentage of the clinical workforce made up by nurses and nurse aides increased to 73%. While the nursing cadre numbers are strong and demonstrate significant improvement since the creation of the Emergency HR Plan, equitable distribution, retention and performance management continue to be challenges. Conclusion This paper illustrates the process, successes, ongoing challenges and current strategies Liberia has used to increase and improve HRH since 2006, particularly the nursing workforce. The methods used here and lessons learned might be applied in other similar settings.

- Abstract
The emergence of SARS-CoV-2 variants has led to several cases among children. However, limited information is available from North African countries. This study describes the SARS-CoV-2 strains circulating in Tunisian pediatric population during successive waves. A total of 447 complete sequences were obtained from individuals aged from 13 days to 18 years, between March 2020 and September 2022: 369 sequences generated during this study and 78 ones, available in GISAID, previously obtained from Tunisian pediatric patients. These sequences were compared with 354 and 274 ones obtained from Tunisian adults and a global dataset, respectively. The variant circulation dynamics of predominant variants were investigated during the study period using maximum-likelihood phylogenetic analysis. Among the studied population, adolescents were the predominant age group, comprising 55.26% of cases. Twenty-three lineages were identified; seven of which were not previously reported in Tunisia. Phylogenetic analysis showed a close relationship between the sequences from Tunisian adults and children. The connections of sequences from other countries were variable according to variants: close relationships were observed for Alpha, B1.160 and Omicron variants, while independent Tunisian clusters were observed for Delta and B.1.177 lineages. These findings highlight the pivotal role of children in virus transmission and underscore the impact of vaccination on virus spread. Vaccination of children, with booster doses, may be considered for better management of future emergences., Competing Interests: Declaration of competing interest Declarations of interest: none of the authors have any conflict of interest., (Copyright © 2024 The Author(s).

- Abstract
Background: In response to the COVID-19 pandemic, multiple vaccines to protect against COVID-19 disease have been developed rapidly. Precise estimates of vaccine effectiveness (VE) vary according to studies design, outcomes measured and circulating variants. The aim of this study was to evaluate the anti-covid-19 vaccine effectiveness in Tunisia., Methods: We conducted a matched case-control study from 2nd to 15th August 2021. Cases and controls were subjects over 60 years of age, selected from the National testing database, regardless vaccine status. A standardized questionnaire was administered for cases and controls to collect information about vaccination status. For cases, vaccination status was defined based on the number of doses received before becoming ill and excludes doses received during the previous two weeks. For matched controls, a reference date based on the case's date of illness onset was defined in order to look at the control's vaccination status before its corresponding case became ill. The odds-ratio was calculated using simple conditional logistic regression. The VE (95 % confidence intervals) was calculated as (1 - odds ratio for vaccination) × 100 %., Results: A sample of 977 matched peers for age and Gender, were included between August 2, and August 15, 2021. The overall vaccine effectiveness (VE) was 70 % [95 % CI 62.8-75.8 %]. Among our sample, 68.1 % of the male population and 56.4 % of the female population were vaccinated with a VE of 73 % [95 % CI 62.9-80.3 %] and 67 % [95 % CI 55.8-75.3 %] respectively, regardless vaccine scheme (complete or incomplete). VE was higher for the age group [60-70 years[ (72.3 % [95 % CI 62.8-79.3 %]). VE was 77.6 % [95 % CI 70.9-82.8 %] to prevent both symptomatic and asymptomatic forms of the disease. Moreover, in prevention from severe forms (treated with oxygen-therapy or admission to an Intensive-care-unit) VE was 86.6 % [95 % CI 75.6-92.7 %] and 98.4 % [95 % CI [79.2-99.8 %] in prevention from COVID-19 deaths with a complete anti-Covid vaccination scheme., Conclusion: The results of our study showed that the anti-Covid-19 vaccines used in Tunisia are efficient to prevent both SARS-COV-2 infections and severe forms related to the disease. This study provided important data on the performance of vaccines in real-world settings that guide decisions about vaccine sustained use., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

- Abstract
Due to the emergence of the SARS-CoV-2 B.1.1.7 (Alpha) variant in the UK in 2020 and its risk of increased transmission, the Ministry of Health in Tunisia implemented a sequencing surveillance strategy for SARS-CoV-2. The aim of this study was to analyze SARS-CoV-2 genomic surveillance data in Tunisia (January 2021-February 2022) and to assess the implementation of the sequencing strategy for SARS-CoV-2 in accordance with national recommendations and the guidance for SARS-CoV-2 genomic surveillance for public health goals. A descriptive study of all sequenced RT-PCR samples sequenced (January 2021-February2022). An internal audit was also done to assess the compliance against standards covering national recommendations and the Guidance for SARS-CoV-2 genomic surveillance for public health goals. A total of 12 simple or composite requirements related to the following areas were included in the audit standards: sampling (one requirements); data collection/analysis (six requirements); partnership (one requirement); and ethical considerations (one requirement). A total of 4819 samples were sent to laboratories and 4278 samples were sequenced. A total of 3648 samples were classified. Positive variants of concern (VOC) samples were 80.92%, differentiated as follows: Alpha, 40.24%; Beta, 0.24%; Gamma, 0.03%; Delta, 45.26%; and Omicron, 14.19%. Three principal phases of VOCs per ISO-week were shown: Alpha 3/2021-25/2021; Delta 26/2021-2/2022; and Omicron 3/2022-6/2022. Levels of compliance were identified; from a total of 12 requirements, 7 were considered as "not met", 4 as "partially met", and 1 as "fully met" but including not totally achieved objectives. In conclusion, the internal audit of the national SARS-CoV-2 sequencing strategy revealed an overall "not met" level of compliance. The results offered a trigger to collaborate with all stakeholders to develop a surveillance strategy for early detection and response to outbreaks caused by VOCs.

- Abstract
Typhoid fever is a significant public health concern in many parts of the world, particularly in developing countries with poor sanitation and hygiene conditions. In July 2016, an outbreak of typhoid fever occurred in Ghannouche, located in the south of Tunisia. This paper reports the results of a field investigation undertaken to identify possible transmission pathways and risk factors in order to propose control and preventive measures. A retrospective cohort study including a passive and active case finding, as well as an environmental and bacteriological investigation was conducted from July to September 2016. A case was defined as a person residing or having stayed in Ghannouche and having presented from the beginning of June clinical signs suggestive of typhoid fever, with, for a confirmed case, laboratory isolation of S.Tyhi, and for a probable case, an epidemiological link with a confirmed case. Attack rates were determined, and risk ratios were estimated with respect to exposures. Unadjusted and adjusted odds ratios were estimated using binary logistic regression. Among the 628 subjects investigated, 102 cases of typhoid fever were identified (74 confirmed and 28 probable) with an overall attack rate of 16.24%. Over 56% of cases were male and those under 10 years old were most affected (38.2%% of cases) with a median age of 12 years (interquartile range 5 to 25 years). The main clinical signs were fever (95%) and diarrhea (57%). Young age (adjusted OR = 0.95 and 95% CI = 0.93-0.97), low level of education (adjusted OR = 4.76 and 95% CI = 1.34-16.81), and the habitat type Arab or rudimentary house (adjusted OR = 4.93 and 95% CI = 2.61-8.27) were the socio-demographic factors independently associated with typhoid fever. Typhoid fever was found to be associated with drinking softened water (adjusted OR = 2.64 and 95% CI = 1.16-4.82), eating raw fruit and vegetables from family gardens (adjusted OR = 6.13 and 95% CI = 3.66-11.06), and using uncontrolled waste disposal (adjusted OR = 3.52 and 95% CI = 2.03-6.94). A total of 110 drinking water samples were analyzed; out of the 38 samples of softened water, 12 were non-compliant and 5 were positive for Salmonella . The screening activity identified two asymptomatic carriers, one of whom was a softened water seller. We concluded that drinking softened water from informal or unauthorized sale units, consuming fruit and vegetables from family gardens, uncontrolled dumping of household waste, and poor socio-economic conditions increase the risk of typhoid fever in this region. Many recommendations were implemented to stop this outbreak and to prevent further episodes.

- Abstract
The extent of the SARS-CoV-2 circulation and the COVID-19 epidemic in Tunisia three months after virus circulation was unknown. The aim of this study was to determine the extent of SARS-CoV-2 infection among household contacts of confirmed COVID-19 cases living in Hot spot areas of Great Tunis, Tunisia by estimating the seroprevalence of antibodies anti SARS-CoV-2 and to identify factors associated to seroprevalence at the first stage of the pandemic in order to guide decision making and to constitute a baseline for further longitudinal analysis of protective immunity to SARS-CoV-2. The National Observatory of New and Emerging Diseases (ONMNE), Ministry of Health Tunisia (MoH), with the support of the Office of the World Health Organization Representative in Tunisia and the WHO Regional Office for the Eastern Mediterranean (EMRO)), conducted a household cross-sectional survey on April 2020 in Great Tunis (Tunis, Ariana, Manouba and Ben Arous). The study was based on the WHO seroepidemiological investigation protocol for SARS-CoV-2 infection. SARS-CoV-2 specific antibodies (IgG and IgM) were qualitatively detected using a lateral immunoassay that detect SARS-CoV-2 nucleocapsid protein and administered by the interviewers. The included subjects were confirmed COVID-19 cases and their households contacts resided in hot spot areas (cumulative incidence rate ≥ 10 cases/100,000 inhabitants) of Great Tunis. Results: In total, 1165 subjects were enrolled: 116 confirmed COVID-19 cases (43 active cases and 73 convalescents cases) and 1049 household contacts resided in 291 households. The median age of participants was 39.0 with 31 years' interquartile range (Min = 8 months; Max = 96 years). The sex ratio (M/F) was 0.98. Twenty-nine per cent of participants resided in Tunis. The global crude seroprevalence among household contacts was 2.5% (26/1049); 95% CI 1.6-3.6%, 4.8%; 95% CI 2.3-8.7% in Ariana governorate and 0.3%; 95% CI 0.01%-1.8% in Manouba governorate. In multivariate analysis, the associated factors independently related to seroprevalence were age ≥25 years (aOR = 5.1; 95% CI 1.2-22.0), history of travel outside Tunisia since January 2020 (aOR = 4.6; 95% CI 1.7-12.9), symptomatic illness in the previous four months (aOR = 3.5; 95% CI 1.4-9.0) and governorate of residence ( p = 0.02). The low seroprevalence estimated among household contacts in Great Tunis reflect the effect of public health measures early taken (national lockdown, borders closed, remote work), the respect of non-pharmaceutical interventions and the efficacy of COVID-19 contact-tracing and case management at the first stage of the pandemic in Tunisia.

- Abstract
Introduction: The Delta variant posed an increased risk to global public health and rapidly replaced the pre-existent variants worldwide. In this study, the genetic diversity and the spatio-temporal dynamics of 662 SARS-CoV2 genomes obtained during the Delta wave across Tunisia were investigated., Methods: Viral whole genome and partial S-segment sequencing was performed using Illumina and Sanger platforms, respectively and lineage assignemnt was assessed using Pangolin version 1.2.4 and scorpio version 3.4.X. Phylogenetic and phylogeographic analyses were achieved using IQ-Tree and Beast programs., Results: The age distribution of the infected cases showed a large peak between 25 to 50 years. Twelve Delta sub-lineages were detected nation-wide with AY.122 being the predominant variant representing 94.6% of sequences. AY.122 sequences were highly related and shared the amino-acid change ORF1a:A498V, the synonymous mutations 2746T>C, 3037C>T, 8986C>T, 11332A>G in ORF1a and 23683C>T in the S gene with respect to the Wuhan reference genome (NC_045512.2). Spatio-temporal analysis indicates that the larger cities of Nabeul, Tunis and Kairouan constituted epicenters for the AY.122 sub-lineage and subsequent dispersion to the rest of the country., Discussion: This study adds more knowledge about the Delta variant and sub-variants distribution worldwide by documenting genomic and epidemiological data from Tunisia, a North African region. Such results may be helpful to the understanding of future COVID-19 waves and variants., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Haddad-Boubaker, Arbi, Souiai, Chouikha, Fares, Edington, Sims, Camma, Lorusso, Diagne, Diallo, Boubaker, Ferjani, Mastouri, Mhalla, Karray, Gargouri, Bahri, Trabelsi, Kallala, Hannachi, Chaabouni, Smaoui, Meftah, Bouhalila, Foughali, Zribi, Lamari, Touzi, Safer, Alaya, Kahla, Gdoura and Triki.)

- Abstract
Introduction: the purpose of this study was to describe the clinical and epidemiological features of COVID-19-related deaths in Tunisia notified at the ONMNE (National Observatory of New and emerging Diseases) between 2
nd March 2020 and 28th February 2021 and to compare COVID-19-related deaths recorded in Tunisia with the international data., Methods: we conducted a national prospective longitudinal descriptive study of data collected from the National Surveillance System of SARS-CoV-2 infection of the ONMNE, Ministry of Health. All COVID-19-related deaths that occurred in Tunisia between March 2020 and February 2021 were included in this study. Data were collected from hospitals, municipalities and regional health departments. Death notifications were collected from multiple data sources (triangulation): The Regional Directorate of Basic Health Care, the ShocRoom (Strategic Health Operations Center), public and private health facilities, the Crisis Unit of the Presidency of the Government, the Directorate for Hygiene and Environmental Protection, the Ministry of Local Affairs and the Environment, as part of the follow-up of confirmed cases by the ONMNE team, positive RT-PCR / TDR post mortem results., Results: during this study, 8051 deaths were recorded, corresponding to a proportional mortality of 10.4%. The median age was 73 years, with an interquartile range of 17 years. Sex-ratio (M/F) was 1.8. The crude death rate was 69.1/100 000 inhabitants and fatality rate was 3.5%. The analysis of the epidemic curve showed 2 peaks of deaths on 29th October 2020 and 22nd January 2021, with 70 and 86 deaths notified respectively. The spatial distribution of mortality showed that the southern Tunisian region had the highest mortality rate. Patients aged 65 and over were most affected (73.7% of cases) with a crude mortality rate of 570.9/100,000 inhabitants and a fatality rate of 13.7%., Conclusion: prevention strategy based on public health measures must be reinforced by the rapid deployment of anti-COVID-19 vaccination, especially for people at risk of death., Competing Interests: Les auteurs ne déclarent avoir aucun conflit d´intérêt., (Copyright: Sonia Dhaouadi et al.)- Published

- Abstract
Since the beginning of the Coronavirus disease-2019 pandemic, there has been a growing interest in exploring SARS-CoV-2 genetic variation to understand the origin and spread of the pandemic, improve diagnostic methods and develop the appropriate vaccines. The objective of this study was to identify the SARS-CoV-2s lineages circulating in Tunisia and to explore their amino acid signature in order to follow their genome dynamics. Whole genome sequencing and genetic analyses of fifty-eight SARS-CoV-2 samples collected during one-year between March 2020 and March 2021 from the National Influenza Center were performed using three sampling strategies.. Multiple lineage introductions were noted during the initial phase of the pandemic, including B.4, B.1.1, B.1.428.2, B.1.540 and B.1.1.189. Subsequently, lineages B1.160 (24.2%) and B1.177 (22.4%) were dominant throughout the year. The Alpha variant (B.1.1.7 lineage) was identified in February 2021 and firstly observed in the center of our country. In addition, A clear diversity of lineages was observed in the North of the country. A total of 335 mutations including 10 deletions were found. The SARS-CoV-2 proteins ORF1ab, Spike, ORF3a, and Nucleocapsid were observed as mutation hotspots with a mutation frequency exceeding 20%. The 2 most frequent mutations, D614G in S protein and P314L in Nsp12 appeared simultaneously and are often associated with increased viral infectivity. Interestingly, deletions in coding regions causing consequent deletions of amino acids and frame shifts were identified in NSP3, NSP6, S, E, ORF7a, ORF8 and N proteins. These findings contribute to define the COVID-19 outbreak in Tunisia. Despite the country's limited resources, surveillance of SARS-CoV-2 genomic variation should be continued to control the occurrence of new variants., (Copyright © 2022. Published by Elsevier B.V.)

- Abstract
Documenting the circulation dynamics of SARS-CoV-2 variants in different regions of the world is crucial for monitoring virus transmission worldwide and contributing to global efforts towards combating the pandemic. Tunisia has experienced several waves of COVID-19 with a significant number of infections and deaths. The present study provides genetic information on the different lineages of SARS-CoV-2 that circulated in Tunisia over 17 months. Lineages were assigned for 1359 samples using whole-genome sequencing, partial S gene sequencing and variant-specific real-time RT-PCR tests. Forty-eight different lineages of SARS-CoV-2 were identified, including variants of concern (VOCs), variants of interest (VOIs) and variants under monitoring (VUMs), particularly Alpha, Beta, Delta, A.27, Zeta and Eta. The first wave, limited to imported and import-related cases, was characterized by a small number of positive samples and lineages. During the second wave, a large number of lineages were detected; the third wave was marked by the predominance of the Alpha VOC, and the fourth wave was characterized by the predominance of the Delta VOC. This study adds new genomic data to the global context of COVID-19, particularly from the North African region, and highlights the importance of the timely molecular characterization of circulating strains.

- Abstract
Background: The aim of this study was to characterize the transmission chains and clusters of COVID-19 infection in Tunisia., Methods: All cases were confirmed by Reverse Transcriptase Polymerase Chain Reaction of a nasopharyngeal specimen. Contact tracing is undertaken for all confirmed cases in order to identify close contacts that will be systematically screened and quarantined. Transmission chains were identified based on field investigation, contact tracing, results of screening tests and by assessing all probable mode of transmission and interactions., Results: As of May 18, 2020, 656 cases out of a total of 1043 confirmed cases of Coronavirus disease 2019 belong to 127 transmission chains identified during the epidemic (mean age 42.36 years, Standard deviation 19.56 and sex ratio 0.86). The virus transmission is the most concentrated in the governorate of Tunis (31.5%), Ariana (10.2%) and Ben Arous (10.2%). Virus transmission occurred 50 times (9.72% of secondary transmission events) between two different governorates. A maximum of seven generations of secondary infection was identified, whereas 62% of these secondary infections belong the first generation. A total of 11 "super spreader" cases were identified in this investigation. Four large clusters have been identified. The evolution of secondary cases highlighted two peaks: one in 2nd April and a second in 16
th April whereas imported cases caused local transmission of virus during the early phase of the epidemic., Conclusion: Correct contact tracing and early active case finding is useful to identify transmission chains and source of infection in order to contain the widespread transmission in the community.- Published

- Abstract
Background: The outbreak of coronavirus disease (COVID-19) continues to constitute an international public health concern. Few data are available on the duration and prognostic factors of the disease. We aimed to study the recovery time among a Tunisian cohort of COVID-19 confirmed patients and identify the prognostic factors., Methods: A retrospective, nationwide study was conducted from March 2 to May 8, 2020, recruiting all patients who were diagnosed with COVID-19, by RT-PCR methods, in Tunisia. Data were collected via phone call interview. Kaplan-Meir Methods and Cox proportional hazards regression models were, respectively, used to study the recovery time and estimate its prognostic factors., Results: One thousand and thirty patients with COVID-19 (aged 43.2 ± 18.2 years, 526 female (51.1%)) were enrolled. Among them 141 (14.8%) were healthcare professionals. Out of 173 patients (17.8%) admitted to the hospital, 47 were admitted in an intensive care unit. Among 827 patients who didn't require specialized care, 55.5% were self-isolated at home, while the rest were in specialized centers. Six hundred and two patients were symptomatic. A total of 634 (61.6%) patients have recovered and 45 (4.4%) patients died. The median duration of illness was estimated to be 31 days (95% CI: [29-32]). Older age (HR = 0.66, CI:[0.46-0.96], P = 0.031) and symptoms (HR = 0.61, CI:[0.43-0.81], P = 0.021) were independently associated with a delay in recovery time. Being a healthcare professional (HR = 1.52, CI: [1.10-2.08], P = 0.011) and patients in home isolation compared to isolation centers (HR = 2.99, CI: [1.85-4.83], P < 10¯
3 ) were independently associated with faster recovery time., Conclusion: The duration of illness was estimated to be 1 month. However, this long estimated duration of illness may not equate to infectiousness. A particular attention must to be paid to elderly and symptomatic patients with closer monitoring.- Published

- Abstract
Background: A wide range of neurological manifestations has been described in COVID-19., Methods: In this nationwide retrospective observational study, patients in Tunisia diagnosed with COVID-19 between the 2nd of March and the 16th of May 2020 were contacted by telephone. We collected demographic and clinical data and specified characteristics and evolution of main neurological symptoms., Results: Of 1034 confirmed COVID-19 patients, 646 were included (mean age 42.17 years old) and 466 (72.1%) had neurological symptoms. Neurological symptoms were isolated 22.7% (n = 106). Headache was the most frequent neurological symptom (n = 279, 41.1%): mainly frontotemporal (n = 143, 51.1%) and mild or moderate (n = 165, 59.1%). When associated with fever (n = 143, 51.3%), headache was more likely to be severe and present at onset. Recovery was reported in 83.2%. Smell and taste impairment were found in 37.9% (n = 245) and 36.8% (n = 238) respectively. Among them, 65.3% (156/239) were anosmic and 63.2% (146/231) were ageusic. A complete improvement was found in 72.1% (174/240) of smell impairment and in 76.8% (179/233) of taste impairment. Myalgia (n = 241, 37.3%) and sleep disturbances (n = 241, 37.3%) were also frequent. Imported cases had more neurological symptoms (p = 0.001). In 14.5%, neurological symptoms preceded the respiratory signs (RS). RS were associated with more frequent (p = 0.006) and numerous (p < 0.001) neurological symptoms., Conclusions: Neurological symptoms in COVID-19 are frequent, can be isolated and present at onset. A total recovery is the most recorded outcome. RS are predictive of neurological symptoms. Studies in to virus and host genetics should be considered to understand the different phenotypes.

- Abstract
Background: Describing transmission dynamics of the outbreak and impact of intervention measures are critical to planning responses to future outbreaks and providing timely information to guide policy makers decision. We estimate serial interval (SI) and temporal reproduction number (R
t ) of SARS-CoV-2 in Tunisia., Methods: We collected data of investigations and contact tracing between March 1, 2020 and May 5, 2020 as well as illness onset data during the period February 29-May 5, 2020 from National Observatory of New and Emerging Diseases of Tunisia. Maximum likelihood (ML) approach is used to estimate dynamics of Rt ., Results: Four hundred ninety-one of infector-infectee pairs were involved, with 14.46% reported pre-symptomatic transmission. SI follows Gamma distribution with mean 5.30 days [95% Confidence Interval (CI) 4.66-5.95] and standard deviation 0.26 [95% CI 0.23-0.30]. Also, we estimated large changes in Rt in response to the combined lockdown interventions. The Rt moves from 3.18 [95% Credible Interval (CrI) 2.73-3.69] to 1.77 [95% CrI 1.49-2.08] with curfew prevention measure, and under the epidemic threshold (0.89 [95% CrI 0.84-0.94]) by national lockdown measure., Conclusions: Overall, our findings highlight contribution of interventions to interrupt transmission of SARS-CoV-2 in Tunisia.- Published

- Abstract
Objective: To identify standards and quality indicators of hip fracture management from the medical literature., Methods: We conducted a "systematic review" on the topic of quality indicators of hip fracture management using PubMed database, during 15 years from 2001 to 2015. The collected publications were studied by two readers to extract the different quality indicators of hip fracture management. These indicators were stratified according to their type (process or outcome) and to the time of health care (pre, per or post-operative)., Results: A total of 41 articles were included in the study: The analysis of these articles highlighted a predominance of Anglo-Saxon papers, an increasing rate of publication over time, a dominance of evaluative studies and a multiplicity of guidelines. A total of 46 quality indicators were identified through these articles. Two third were classified as procedural items and 60% were about post-operative hip fracture management. The most assessed indicators and standards, among those related to the preoperative care, were time to surgery (34%) and patient clinical condition assessment (11%). During the operation time, the most assessed indicator was the proportion of patients who have had spinal anesthesia (73%). For the postoperative care, the most common indicators and standards were length of hospital stay (12%), osteoporosis treatment prescription (8%), mattresses use to prevent pressure ulcer (7%), pressure sores occurring (7%) and in hospital mortality (7%)., Conclusion: This systematic review allowed to identify the main indicators recommended to evaluate the management of hip fracture. The continuous monitoring of these indicators should be generalized in maghrebian countries using strategic dashboards in all hospitals and clinics treating this pathology.

- Abstract
Background: Despite their high prevalence and severity among youth, national researches concerning eating disordered behavior among undergraduate students remains rare. Hence, it is imperative to determine the amplitude and to identify the risk factors of eating disorders (ED) to enable effective interventions., Aim: To assess prevalence and associated factors of (ED) among health occupation students in the university of Monastir during 2013., Methods: A cross sectional study using a self-administered questionnaire which was distributed by approaching directly students. The following items were collected: demographic, socioeconomic and educational characteristics; self-esteem; previous dieting; perceived stress score(Cohen's scale); depression (Beck Depression); sleep quality; sport practice; cyber addiction (Orman scale) and alcohol regular use (CRAFT-ADOPSA questionnaire). SCOFF questionnaire was used to identify students at risk of ED., Results: A total of 974 students were included in the study. The mean age of students was 22.8 (Standard Deviation=2.2) with a sex ratio of 0.43. The prevalence of ED according to SCOFF questionnaire was 35%; 95% CI [32.0-38.5]. It was higher among female (39.8; 95% CI [35.8-43.7]) compared to male (24.3; 95% CI [18.8-29.7]) with a statistically significant difference (p<10-3). The risk factors associated independently with an eating disorder were "Previous dieting" (aOR=4.13; 95% CI [2.79-6.12]),"Sex" (aOR=1.77. 95% CI [1.13-2.77]) and "Repeat a year" (aOR=1.76; 95% CI [1.09-2.85])., Conclusion: The prevalence of health occupation students at risk of ED was high. These results emphasizes the need for diversified and adapted prevention and health education policies as well as a need for a systematic screening of ED among students in order to start an early treatment that can improve their prognosis.

- Abstract
Background: Determining the performance level of hemodialysis facilities, including an evaluation of biological tests, is a prerequisite for quality assessment of these healthcare structures., Objective: The purpose of this work was to evaluate the compliance and adequacy of biological tests performed in 2014 in Center-East Tunisia hemodialysis units., Methods: Data were collected using an analysis grid for 15 biological indicators including 11 process items and four results items used to determine the compliance and adequacy rates respectively., Results: This study included 660 hemodialysis patients (sex ratio 1.16; mean age 53.9±15.32 years). A low level of compliance was noted for several biological tests (blood glucose: 0.8%; hemoglobin 34.5%). The rate of adequacy of the biological results was insufficient, especially for anemia (32.7%) and calcium-phosphorus surveillance (41.8%). Intercenter and inter-region variability was noted, both for compliance and for adequacy of biological tests., Conclusion: This study demonstrated low compliance of biological tests performed for hemodialysis patients and the non-adequacy of the results obtained. It is thus urgent to institute a quality management system for biological tests performed in hemodialysis units., (Copyright © 2018 Elsevier Masson SAS. All rights reserved.)

- Abstract
Objective: Measure the prevalence of smoking among students of health sciences Faculties in Monastir (Tunisia) and identify factors associated with smoking behavior., Methods: A cross-sectional study based on a self-administered questionnaire conducted among students registered in their second, fourth and sixth year at the Faculties of Medicine and Pharmacy in Monastir, in 2013. Smoker was the subject who, at the time of the survey, smoked at least one cigarette per day. Academic difficulties were used to denote any of the following incidents that a student may experience: passing exams at the retake session, revalidating an internship or repeating a school year. A logistic regression analysis was used to identify factors associated with smoking., Results: The number of participants was 634 (285 Medical students and 349 Pharmacy students); they were 170 males and 464 females. The prevalence of smoking was 15%; 95% IC [12.1-17.7]. It was nearly five times higher among male compared to female students (35.3%; 95% IC [28.1-42.5]) vs 7.5%; 95% IC [5.1-9.9]); It was also higher among Pharmacy students than among Medical students (18.9%; 95% IC [14.8-23.0]) vs 10.2%; 95% IC [6.7-13.7]). In the multivariate analysis, the Faculty of Pharmacy (ORa=3.081; 95% IC=[1.7-5.7]), the male sex (ORa=6.929; 95% IC [3.9-12.0]) and the academic difficulties (ORa=1.854; 95% IC [1.02-3.38]) were found to be significantly associated with smoking., Conclusion: The level of tobacco use found among Medical and Pharmacy students is alarming. This serious problem has a negative impact on their behavior and can hinder their role model as future health professionals. Greater efforts are needed to develop anti-smoking programs, to educate students and to offer psychological support to deal with school difficulties.

Background: English is becoming nowadays the universal language of science. Rresearch published in English can be considered as a bibliometric indicator of the scientific productivity., Aim: We sought to describe the evolution of the Tunisian medical publications written in English over the period from 2004 to 2014., Methods: Medline's database was consulted using a research query associating the names of the country and the main university cities both in French and in English. The articles with a Tunisian health affiliation were retained but the articles of dentistry, pharmacy and non-medical fields were not included., Results: We counted 979 English language Tunisian medical articles published during the three tracer years of the study: 2004, 2009 and 2014. The increase rate was about 38% between 2004 and 2014. The contribution of medical fields in English language publications was important but showed a clear decrease over time. The retrieved articles did not have the same distribution according to the specialties and the institutions. The distribution according to the journals showed that these articles were mainly published by foreign journals with an increasing impact factors between 2004 and 2014., Conclusion: The English language Tunisian medical productivity had shown an important increase over time but many specialties and institutions still not enough implicated in this production.Therefore, increasing research funding, improving the physicians' research methodology and English writing capacities are likely needed to improve the Tunisian medical output.
