Introduction: Tunisian emigrants may consume psychoactive substances in other countries. This community is exposed to sociocultural and legal contexts different from those in Tunisia and the degree of acculturation would tend to increase over time. However, data on the use of psychoactive substances, particularly cannabis, in this particular population are scarce. Objectives: This study aims to determine the profile of Tunisian young adults residing abroad who use cannabis. Methods: We conducted a cross-sectional, descriptive and analytic study. It was carried out in the form of an online survey. We focused on young Tunisians people who have completed their secondary studies at the pilot high school of Sfax and currently residing abroad. Data collection was through Google Forms administred questionnaire. Results: Thirty-five participants were included in our study. Cannabis use behavior affected 48.6% of them (N=17)) and it was done with friends in a festive setting in 88% of cases (N=15). Cannabis use was more common among people who were single (p=0.001), living alone (p=0.047), had a psychiatric history (p=0.032) and hanging out with friends who also smoked cannabis (p=0.032).Cannabis use was also more common among cigarette smokers (p=0.000) and alcohol consumers (p=0.000). It was significantly more common among people who shared erroneous beliefs about cannabis, that it is a mild drug (p= 0.024) and that it does not cause dependence (p= p=0.042). Conclusions: Cannabis use among Tunisian young adults residing abroad seems to be a form of poly-consumption, more common among singles, living alone and having a psychiatric vulnerability. These findings underscore the need for targeted interventions and educational initiatives to address cannabis use within this specific population.

The present work was aimed to investigate the life cycle and the effect of different initial population densities of Globodera rostochiensis on potato yield and growth on the susceptible potato cultivar, Spunta, in Algerian environmental conditions. The length of the life cycle of G. rostochiensis differed among growing seasons and was 72 days or 699 DD6.2 for potatoes planted in mid-February and 66 days or 496 DD6.2 for potatoes planted in early November. A significant reduction in growth and potato yields was observed. The increase of initial Population densities (Pi) of G. rostochiensis were associated with a significant reduction in plant growth and potato yields. The maximum yield and plant height reductions were 85 and 75%, respectively, at the highest Pi of 512 eggs g-1 soil. The final nematode Population density (Pf) increased with the increase of the initial population densities. The Reproductive factor (Rf) initially increased with the increase of Pi up to 4 eggs g-1 soil and then decreased for Pi4 ؛, suggesting an intraspecies competition. Results contribute to the knowledge of G. rostochiensis thermal time requirements in Algerian environmental conditions and can be a valuable tool to develop appropriate potato cyst nematode control strategies considering that the nematode can also cause severe damage and yield losses at very low Pi densities.

Radiotherapy (RT) for head and neck cancer is now guided by cone-beam computed tomography (CBCT). We aim to identify a CBCT radiomic signature predictive of progression to RT. A cohort of 93 patients was split into training (n = 60) and testing (n = 33) sets. A total of 88 features were extracted from the gross tumor volume (GTV) on each CBCT. Receiver operating characteristic (ROC) curves were used to determine the power of each feature at each week of treatment to predict progression to radio(chemo)therapy. Only features with AUC > 0.65 at each week were pre-selected. Absolute differences were calculated between features from each weekly CBCT and baseline CBCT1 images. The smallest detectable change (C = 1.96 × SD, SD being the standard deviation of differences between feature values calculated on CBCT1 and CBCTn) with its confidence interval (95% confidence interval [CI]) was determined for each feature. The features for which the change was larger than C for at least 5% of patients were then selected. A radiomics-based model was built at the time-point that showed the highest AUC and compared with models relying on clinical variables. Seven features had an AUC > 0.65 at each week, and six exhibited a change larger than the predefined CI 95%. After exclusion of inter-correlated features, only one parameter remains, Coarseness. Among clinical variable, only hemoglobin value was significant. AUC for predicting the treatment response were 0.78 (p =.006), 0.85 (p <.001), and 0.99 (p <.001) for clinical, CBCT4-radiomics (Coarseness) and clinical + radiomics based models respectively. The mean AUC of this last model on a 5-fold cross-validation was 0.80 (±0.09). On the testing cohort, the best prediction was given by the combined model (balanced accuracy [BAcc] 0.67 , p <.001). We described a feature selection methodology for delta-radiomics that is able to select reproducible features which are informative due to their change during treatment. A selected delta radiomics feature may improve clinical-based prediction models. [ABSTRACT FROM AUTHOR]

Introduction: Psychological vulnerability and problematic psychotropic drug use among medical residents are critical and intricate areas of study in the field of healthcare and mental well-being. This topic looks into the potential links between the psychological vulnerabilities experienced by medical residents, which are frequently associated with the demanding nature of their profession, and their use of psychotropic drugs in a way that poses problems or risks. Exploring this relationship is critical for understanding the mental health challenges that medical residents face and developing effective strategies to support their psychological well-being. Objectives: to identify the psychological factors linked to problematic psychotropic drug use in medical residents. Methods: We conducted a cross-sectional descriptive and analytical study among Tunisian medical residents between August and September 2022. We used a self-administered questionnaire with a data collection form, the DAST-10 (Drug Abuse Screening Test) scale, and the DASS-21 (Depression, Anxiety, and Stress Scale) in an online survey. Data was analyzed using the 20th version of the SPSS software. Results: The sample consisted of 80 medical residents. Among them, 23.8% (n=19) had reported a previous use of psychotropic drugs, and 15% (n=12) a misuse (without a prescription and/or without following the prescription). The DAST-10 revealed that 6 residents (31.6%) had problematic use of psychotropic drugs. A high level of stress on the DASS-21 scale was associated with a problematic use (p=0.01) and a misuse (p=0.01) of psychotropic drugs. Furthermore, residents with high stress levels were more likely to demonstrate problematic use of psychotropic drugs (p=0.004). Such problematic use was correlated with personal history of anxiety disorders (p=0.01). Furthermore, residents with problematic psychotropic drug use had higher anxiety and depression scores on the DASS-21 scale (p>0.05). Conclusions: Our findings revealed a concerning prevalence of psychotropic drug use among medical residents and an association with high stress levels. This result emphasizes the need for targeted interventions to support young doctors' mental health. Disclosure of Interest: None Declared [ABSTRACT FROM AUTHOR]

Introduction: Understanding adolescents perceptions of their weight status and the factors influencing these perceptions is pivotal for developing targeted interventions and policies to counteract the rising obesity trends. Objectives: This cross-sectional study aimed to determine the accuracy of weight status perceptions among Tunisian adolescents compared to objective metrics and to identify sociodemographic characteristics and life habits associated with the underestimation of weight status. Methods: A cross-sectional, school-based study was conducted among a randomized sample of adolescents attending secondary schools in Sousse, Tunisia. A total of 1399 students participated, with anthropometric measurements taken, and a pre-tested Arabic questionnaire administered to gather sociodemographic data and perceived weight status, assessed using the Figure Rating Scale (FRS). The accuracy of perceived weight status was determined by comparing the measured weight status with participants; self-reported perceptions. We evaluated the association between body weight distortion and life habits which included regular physical activity, screen time (time spent on internet per day), number of fruits and vegetables consumed per day, and fast-food consumption. Results: The study achieved an 86.68% response rate, with over half of the participants being female (60.5%), and the average age being 17 years. The majority of adolescents (41%) perceived themselves as having normal body weight, while 34.5% perceived themselves as underweight, 16.6% as overweight, and 7.9% as obese. However, based on BMI categories, 72.6% had a normal measured weight, 20.4% were overweight, and 6.9% were obese. A substantial proportion of participants (45.6%) underestimated their weight status, with a significant proportion being objectively overweight or obese (26%). Furthermore, we found a significant association between the perception of weight accuracy with four correlates: gender, mother educational level, regular physical activity, and the number of fruits and vegetables consumed per day. Conclusions: The findings revealed a disparity between perceived and actual weight status among Tunisian adolescents, with a significant underestimation of weight status, particularly among those who are overweight or obese. The results highlighted the crucial need for interventions that address weight perception inaccuracies and promote healthy weight awareness and management among adolescents in Tunisia. The study underscored the importance of further research to understand the development and progression of body weight underestimation throughout adolescence and the roles of lifestyle behaviors in shaping weight perceptions.

Objectives: To determine the prevalence of vitamin B12 deficiency in a Tunisian population with type 2 diabetes (T2D) on metformin treatment for more than three years and to identify its risk factors. Methods: This is a cross-sectional study conducted on 257 patients with T2D treated with metformin for at least three years. Patients were divided into two groups according to their vitamin B12 status. Low vitamin B12 was defined as ≤ 203 pg/mL. Results: The mean age of the patients was 59.8  ±  7.9 years. The mean duration of metformin use was 10.2  ±  5.2 years. The mean vitamin B12 level was 294.9  ±  156.4 pg/mL. The prevalence of vitamin B12 deficiency was 28.4%. Male gender, HbA1c < 7% and hyperhomocysteinemia were significantly associated with vitamin B12 deficiency (respectively p   =  0.02, p  < 0.001, p  < 0.001). Homocysteine level was negatively correlated with vitamin B12 level ( r   =  -0.2, p   =  0.001). Dose and duration of metformin treatment, peripheral neuropathy and anemia were not associated with vitamin B12 deficiency. On multivariate analysis, HbA1c < 7% and hyperhomocysteinemia were independently associated with vitamin B12 deficiency (respectively OR = 3.2, 95%CI  =  [1.6-6.3] and OR = 2.3, 95%CI  =  [1.2-4.2]). Discussion: The prevalence of vitamin B12 deficiency in patients with T2D on metformin treatment was high. Hyperhomocysteinemia is associated with vitamin B12 deficiency suggesting that the deficit occurs at the tissue level., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: The delineation of organs-at-risk and lymph node areas is a crucial step in radiotherapy, but it is time-consuming and associated with substantial user-dependent variability in contouring. Artificial intelligence (AI) appears to be the solution to facilitate and standardize this work. The objective of this study is to compare eight available AI software programs in terms of technical aspects and accuracy for contouring organs-at-risk and lymph node areas with current international contouring recommendations., Material and Methods: From January-July 2023, we performed a blinded study of the contour scoring of the organs-at-risk and lymph node areas by eight self-contouring AI programs by 20 radiation oncologists. It was a single-center study conducted in radiation department at the Lorraine Cancer Institute. A qualitative analysis of technical characteristics of the different AI programs was also performed. Three adults (two women and one man) and three children (one girl and two boys) provided six whole-body anonymized CT scans, along with two other adult brain MRI scans. Using a scoring scale from 1 to 3 (best score), radiation oncologists blindly assessed the quality of contouring of organs-at-risk and lymph node areas of all scans and MRI data by the eight AI programs. We have chosen to define the threshold of an average score equal to or greater than 2 to characterize a high-performing AI software, meaning an AI with minimal to moderate corrections but usable in clinical routine., Results: For adults CT scans: There were two AI programs for which the overall average quality score (that is, all areas tested for OARs and lymph nodes) was higher than 2.0: Limbus (overall average score = 2.03 (0.16)) and MVision (overall average score = 2.13 (0.19)). If we only consider OARs for adults, only Limbus, Therapanacea, MVision and Radformation have an average score above 2. For children CT scan, MVision was the only program to have a average score higher than 2 with overall average score = 2.07 (0.19). If we only consider OARs for children, only Limbus and MVision have an average score above 2. For brain MRIs: TheraPanacea was the only program with an average score over 2, for both brain delineation (2.75 (0.35)) and OARs (2.09 (0.19)). The comparative analysis of the technical aspects highlights the similarities and differences between the software. There is no difference in between senior radiation oncologist and residents for OARs contouring., Conclusion: For adult CT-scan, two AI programs on the market, MVision and Limbus, delineate most OARs and lymph nodes areas that are useful in clinical routine. For children CT-scan, only one IA, MVision, program is efficient. For adult brain MRI, Therapancea,only one AI program is efficient., Trial Registration: CNIL-MR0004 Number HDH434., Competing Interests: Declarations.

The interplay between human microbiota and various physiological systems has garnered significant attention in recent years. The gut microbiota plays a critical role in maintaining physiological homeostasis and influences various aspects of human health, particularly via the gut brain axis. Since 2017, the challenging concept of the gut-retina axis has emerged thanks to a network analysis emphasizing the potential role of the gut microbiota disruption in the development of the age-related macular degeneration and further retinal damages. Many other ocular disorders have been linked to the dysbiosis of the gut microbiota, including uveitis and glaucoma. It has been shown that age related macular degeneration can be prevented or reversed using a diet that induces changes in the gut microbiota. The potential link between the gut microbiota as well as others types of microbiota such as the ocular surface microbiota and the development/progression of age related as well as inherited retinal degenerations and other degenerative eye diseases, has recently been broadened. Therefore, the pathogenesis of several eye diseases has recently been associated with a larger perception called the gut eye axis. This mini-review examines the potential mechanisms underlying the gut eye axis and suggests implications for the management of eye diseases. By understanding the modulation of the gut microbiota and its impact on eye disease, this mini-review provides insight into potential therapeutic interventions and avenues for future research., 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 © 2024 Kammoun, Rekik, Dlensi, Aloulou, Smaoui, Sellami, Trigui, Gargouri, Chaari, Sellami, Elatoui, Khemakhem, Hadrich, Neji, Abdelmoula and Bouayed Abdelmoula.)

Lead (Pb) is one of the most common heavy metals with toxicological effects on many tissues in humans as well as animals. In order to counteract the toxic effects of this metal, the administration of synthetic or natural antioxidants is thus required. The aim of this study was to examine the beneficial effect of the aqueous extract of Ononis natrix (AEON) against lead acetate-induced damage from a behavioral, biochemical, and histological point of view. Forty-eight male mice were divided into four equal groups: Ctr (control); Pb (lead acetate 1g/l); Pb + On 100 mg/kg (lead acetate 1 g/l + AEON 100 mg/kg); Pb + On 500 mg/kg (lead acetate 1 g/l + AEON 500 mg/kg). AEON was administered orally from day 21 after the start of lead exposure up to the end of the experiment. The results revealed that lead induced behavioral disorders, increased serum levels of liver markers (AST, ALT, and bilirubin), as well as kidney markers (urea and creatinine). At the same time, levels of thiobarbituric acid reactive substances (TBARS) and glutathione peroxidase (GPx) increased significantly. Moreover, Pb caused structural changes in the liver and kidneys of Pb-exposed mice. However, AEON administration significantly improved all lead-induced brain, liver, and kidney dysfunctions. Our results suggest that AEON could be a source of molecules with therapeutic potential against brain, liver, and kidney abnormalities caused by lead exposure., (© 2024.

Background. Catheter-related bloodstream infection (CRBSI) is defined as the presence of bacteremia originating from a venous catheter and is one of the most common and costly complications, often followed by death and septicemia. Objectives. To evaluate the effectiveness of specific interventions on CRBSI reduction rates and other outcomes. Materials and Methods. The review has been performed by consulting scientific evidence through the PUBMED/MEDLINE database using MeSh terms and Boolean operators. Studies related to the formulated hypothesis have been selected and included. Results. The results showed that thanks to a series of interventions it was possible to decrease the risk of CRBSI and lowered the risk of catheter removal, hospitalization rate and morbidity rate. Discussion and Conclusions. Proper catheter care and follow-up procedures are the first steps in preventing infection. Audit and education of dialysis unit personnel is essential., (Copyright by Società Italiana di Nefrologia SIN, Rome,Italy.)

Background: This study explored the impact of occupational stress, personal factors, and physical conditions on work productivity decline (WPD) among workers in the Tunisian onshore oil and gas industry., Methods: We conducted a cross-sectional survey among 246 onshore oil installation workers of a Tunisian private oil company. 94 employees (48%) participated in this study. We used the Job Content Questionnaire to evaluate occupational stress and the Work Productivity and Activity Impairment Questionnaire to assess the WPD., Results: Data were analysed using R software. This study exclusively included male workers, with an average age of 41.1 ± 9.5 years. Binary logistic regression analysis identified low social support and job-strain situation as the most associated risk factors (OR >3). The random forest model suggested that professional category, job-strain situation, low social support, and iso-strain situation were the most important variables in predicting WPD., Conclusion: These data provided evidence that petroleum workers faced a monotonous lifestyle in the workplace, leading to high levels of occupational stress that affected their work productivity. This study is the first in Tunisia in the oil sector., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Indian Journal of Occupational and Environmental Medicine.)

Aberrant mechanotransduction and compromised epithelial barrier function are associated with numerous human pathologies including inflammatory skin disorders. However, the cytoskeletal mechanisms regulating inflammatory responses in the epidermis are not well understood. Here we addressed this question by inducing a psoriatic phenotype in human keratinocytes and reconstructed human epidermis using a cytokine stimulation model. We show that the inflammation upregulates the Rho-myosin II pathway and destabilizes adherens junctions (AJs) promoting YAP nuclear entry. The integrity of cell-cell adhesion but not the myosin II contractility per se is the determinative factor for the YAP regulation in epidermal keratinocytes. The inflammation-induced disruption of AJs, increased paracellular permeability, and YAP nuclear translocation are regulated by ROCK2, independently from myosin II activation. Using a specific inhibitor KD025, we show that ROCK2 executes its effects via cytoskeletal and transcription-dependent mechanisms to shape the inflammatory response in the epidermis., Competing Interests: The authors declare no competing interests., (© 2023 The Author(s).)

Introduction: Both exercise and pre-meal metformin could lower postprandial glucose and lipid profiles., Aims: To explore whether pre-meal metformin administration is superior to metformin administration with the meal in reducing postprandial lipid and glucose metabolism, and whether its combination with exercise confer superior benefits in metabolic syndrome patients., Materials and Methods: In a randomized crossover design, 15 metabolic syndrome patients were assigned to 6 sequences including 3 experimental conditions: metformin administration with a test meal (met-meal), metformin administration 30 min prior to a test meal (pre-meal-met) with or without an exercise bout designed to expend 700 Kcal at 60% VO 2 peak performed the evening just before pre-meal-met condition. Only 13 participants (3 males, 10 females; age: 46 ± 9.86, HbA1c: 6.23 ± 0.36) were included in the final analysis., Results: Postprandial triglyceridemia was unaffected by any condition (all P > .05). However, both pre-meal-met (-7.1%, P = .009) and pre-meal-metx (-8.2%, P = .013) significantly reduced total cholesterol AUC with no significant differences between the two latter condition ( P = .616). Similarly, LDL-cholesterol levels were significantly lower during both pre-meal-met (-10.1%, P = .013) and pre-meal-metx (-10.7%, P = .021) compared to met-meal with no difference between latter conditions ( P = .822). Plasma glucose AUC was significantly reduced by pre-meal-metx compared to both pre-meal-met (-7.5%, P = .045) and met-meal (-8%, P = .03). Insulin AUC was significantly lower during pre-meal-metx compared to met-meal (-36.4%, P = .044)., Conclusions: Metformin administration 30 minutes prior to meal seems to exert favorable effects on postprandial TC and LDL-Cholesterol levels compared to its administration with meal. Addition of one exercise bout only improved postprandial glycemia and insulinemia., Trial Registry: Pan African clinical trial registry, Identifier PACTR202203690920424.

Context: Chondroitin 6 sulphate (C6S) is a glycosaminoglycan (GAG) whose accumulation is notable in mucopolysaccharidosis type IVA and VII. Flaxseed, Linum usitatissimum L. (Linaceae) (FS), is reported to have comparable properties to those of soybean, a source of genistein, a potential new treatment for MPSs., Objective: We assess the effect of total ethanol flaxseed extract (EFSE) in an animal model of C6S accumulation., Materials and Methods: The study was performed in adult male Wistar rats ( n  = 24) for 15 successive days. The animals were divided into four groups: (1) control injected with physiological saline buffer, (2) intoxicated rats injected intraperitoneally with C6S, (3) intoxicated with C6S and treated with EFSE, and (4) treated with EFSE. All groups were subjected to histopathological and biochemical studies. The antioxidant and phytochemical properties of EFSE were examined., Results: Dry EFSE contains total phenols (6.28 mg EAG/g), condensed tannins (2.98 mg ECAT/g) and flavonoids (0.44 mg ECAT/g) with high antioxidant potential [RPE (IC 50 = 8.37 ± 0.176), DPPH (IC 50 = 12.79 ± 0.273)]. The LD 50 is higher than 5000 mg/kg. The histopathological examination showed an accumulation of C6S in the C6S intoxicated group, which disappeared in the C6S-EFSE treated group. GAGs assays showed an increased excretion in the C6S intoxicated group and increased excretion of 14% in the C6S-EFSE group compared to the C6S group., Discussion and Conclusions: EFSE showed significant potential for chelation. Its use for the treatment of GAG accumulation could be suggested and generalized to a larger study population.

Post-COVID19 patients suffer from persistent respiratory, cardiovascular, neurological, and musculoskeletal health complaints such as dyspnea, chest pain/discomfort, and fatigue. In Tunisia, the potential benefits of a cardiorespiratory rehabilitation program (CRRP) after COVID19 remain unclear. The main aim of this study was to evaluate the impact of a CRRP on submaximal exercise capacity, evaluated through the 6-min walk test (6MWT) data in post-COVID19 Tunisian patients. This was a cross-sectional study including 14 moderate to severe COVID19 patients aged from 50 to 70 years. CRRP was performed after the end of patients' hospitalization in COVID19 units for extensive or severe extents of COVID19. Dyspnea (modified medical research council), spirometry data, handgrip strength values, 6MWT data, and 6-min walk work (i.e., 6-min walk distance x weight) were evaluated 1-week pre-CRRP, and 1-week post-CRRP. CRRP included 12 sessions [3 sessions (70 min each)/week for 4 weeks]. Exercise-training included aerobic cycle endurance, strength training, and educational sessions. Comparing pre- and post- CRRP results showed significant improvements in the means±standard deviations of dyspnea by 1.79 ± 0.80 points ( p < 0.001), forced expiratory volume in one second by 110 ± 180 ml ( p = 0.04), 6-min walk distance by 35 ± 42 m ( p = 0.01), 6-min walk work by 2,448 ± 3,925 mkg ( p = 0.048), resting heart-rate by 7 ± 9 bpm ( p = 0.02) and resting diastolic blood pressure by 6 ± 10 mmHg ( p = 0.045). In Tunisia, CRRP seems to improve the submaximal exercise capacity of post-COVID19 patients, mainly the 6-min walk distance and work., 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.

Background: Pregnancy affects a woman's susceptibility to and severity of certain infectious diseases. Central neuraxial block for analgesia during labor is superior to nonneuraxial methods in efficacy, safety, and maternal satisfaction. Although Coronavirus disease (COVID-19) can be vertically transmitted from mother to fetus, little is known about the effects of COVID-19 on pregnant women or about anesthesia management and the risk of adverse effects related to neuraxial techniques in women with untreated COVID-19 during gestation., Aim: This investigation assesses the effects of neuraxial analgesia during labor of COVID-19-positive parturients on their hemodynamic stability., Results: The study was conducted on 64 patients and involved 32 parturients positive for SARS-CoV-2 by polymerase chain reaction (PCR) and a similar number of control "negative" patients. The affected group had an uneventful course during gestation. Seven were positive for ground-glass opacities on chest X-rays, and none underwent computed tomography (CT) scans. Two neonates were PCR-positive for SARS-CoV-2, and all 32 neonates were released from the hospital. No clinical differences were observed between the neonates in the COVID-19 and control groups. Although parturients in both groups were hemodynamically stable, hemodynamic stability was subnormal in the COVID-19 group regarding blood pressure, oxygen saturation, heart rate, and body temperature. None of the women in either group required a vasopressor or oxygen supplementation during delivery. No other clinical differences were observed between the COVID-19 and control groups., Conclusion: This is the first case-controlled study testing the anesthetic implications of neuraxial labor analgesia in pregnant, COVID-19-positive women. Although management of neuraxial labor analgesia did not differ in pregnant women positive and negative for COVID-19, their hemodynamic characteristics differed significantly. Therefore, care is required to prevent adverse outcomes in pregnant women positive for COVID-19., (© 2022 Abdalla, Nahid, Valappil, Gudavalli, Sellami, Korichi, Ahmad, Cespedes, Gopalakrishnan, licensee HBKU Press.)

Heavy metal pollution is a challenging concern that threatens the soil environment and human health worldwide. The purpose of this work is to assess the heavy metals (Cr, Cu, Zn, and Pb) pollution in the urban and peri-urban soils in and around Setif city, eastern Algeria. The work combines chemical analysis of thirty-six soil samples, statistical valuation and interpretation of chemical data and pollution indices (geoaccumulation index, pollution index, and integrated pollution index) with thematic mapping. The average concentrations (in mg/kg) of Cd, Cr, Cu, Pb, and Zn were found < 0.02, 43.35, 43.75, 331.20, and 78.26 mg/kg, respectively. Compared with the French regulatory limits (AFNOR U44-041), Cd, Cr, and Cu still non-hazardous at Setif city scale; however, Zn and Pb concentrations are two to three times higher than the background values referred to the Chinese [Formula: see text] standard (GB15618-1995). The pollution indices indicate that Pb and Zn represent the highest threats among the studied pollutants and polluted wide areas of anthropogenic activities located respectively in the oldest district of the city, near the industrial zone and near uncontrolled landfill of domestic and industrial waste. Cu, Pb, and Zn originate seemly from vehicle emission, particles of brakes and tires, and industrial emissions. However, Cr distribution is uncorrelatable with anthropogenic sources. The Cr with an average concentration less than the background value derives seemly from animal feces and organic fertilizers. The integrated pollution index shows that the accumulation of heavy metals in the soils of Setif city from anthropogenic sources reached alarming levels that can disperse into the environment and threaten the human health. The urbanization and industrial development of Setif city are expected to grow and a subsequent heavy metal pollution will be rising prior issue. Corrective measures should be endeavored by the local authorities to mitigate the current environmental situation and a sustainable development plan for the city should be anticipated to guarantee optimal future environmental conditions., (© 2022.

Hepatic encephalopathy (HE) is a neurophysiological syndrome secondary to acute or chronic liver failure. Studies showed that HE patients exhibit a deficit in motor coordination, which may result from cerebellar functional impairment. The aim of this study is to assess the time-dependent alteration of locomotor behavior and the glial and neuronal alteration in rat with acute HE induced chemically. The study was carried out in male Sprague-Dawley rats with thioacetamide (TAA) induced acute liver failure at different stages 12 h, 24 h and 36 h. Hepatic and renal functions were assessed via various biochemical and histopathological examinations, while the cerebellum and the midbrain were examined using histology and immunohistochemistry for tyrosine hydroxylase (TH), cyclooxygenase-2 (COX-2) and glial fibrillary acidic protein (GFAP). We used as well, the open field test and the Rotarod test for assessing the locomotor activity and coordination. Our data showed a progressive loss of liver function and a progressive alteration in locomotor behavior and motor coordination in acute HE rats. In the cerebellum, we noted an increase in the degeneration of cerebellar Purkinje neurons parallel to increased COX-2 immunoreactivity together with astrocytic morphology and density changes. Likewise, in substantia nigra pars compacta, TH levels were reduced. We showed through the current study, a progressive deterioration in locomotor behavior in acute HE rats, as a result of Purkinje neurons death and a deficient dopaminergic neurotransmission, together with the morpho-functional astroglial modifications involving the oxidative stress and neuroinflammation., (Copyright © 2021.
