Introduction: From their earliest hours, human beings are able to identify a source of food and to feed themselves. Feeding is therefore one of the most instinctive human functions. It is regulated by several factors (physiological, psycho-affective and environmental) whose disruption can lead to eating disorders. Objective: The aim of this study was to investigate eating disorders among students in the town of Parakou in 2023. Method: Descriptive cross-sectional study conducted from January to July 2023 in various universities in the city of Parakou, Benin. The study population consisted of all students in grades 1 to 7 at these universities. A two-stage non-proportional stratified sampling technique combined with a simple random draw was adopted. The Eating Attitude Test-26, Bulimia Inventory Test Edinburgh and a set of questions focusing on the diagnostic criteria for pica were used to screen for pica and other disorders such as anorexia, bulimia nervosa and binge eating disorder. Data were analyzed using SPSS (Statistical Package for Social Sciences) version 25. Results: A total of 607 students were surveyed, 323 of whom had eating disorders. A prevalence of 53.21% of students at risk of eating disorders was found. In relation to the total population, the prevalences of anorexia, bulimia nervosa, binge eating disorder and pica were 45.96%, 0.82%, 15.48% and 12.68% respectively. In multivariate analysis, seven factors explained the risk to develop at least one eating disorder among the students surveyed. These were: urban area of residence (OR (95% CI) = 5.059 (1.75 - 14.65);p = 0.003);year of study (OR (95% CI) = 0.47 (0.28 - 0.79);p = 0.035);type of university attended (private university: OR (95% CI) = 1.63 (1.08 - 2.44);p = 0.019);parents’ marital status (couple or not) (OR (95% CI) = 1.50 (1.01 - 2.24);p = 0.046);father’s level of education: secondary (OR (CI 95%) = 3.85 (1.96 - 7.54);p 0.001)/higher (OR (CI 95%) = 2.83 (1.36 - 5.86);p = 0.005);mother’s one:

Introduction: Post-traumatic stress disorder (PTSD) is defined as “actual exposure to death or the threat of death, serious injury or sexual violence”, either directly or indirectly, resulting in a symptomatic procession of repetition, avoidance, neurovegetative hyperactivity and individualized symptoms, with or without negative cognitive and mood changes. It therefore goes without saying that the defence and security forces constitute a high-risk population in need of attention. Objective: To study post-traumatic stress disorder in defence and security forces in the city of Parakou in 2023. Methods: Descriptive cross-sectional study conducted from December 2022 to July 2023. The study population consisted of active military, republican police and firefighters in the city of Parakou in 2023. Non-proportional stratified sampling was used, given the inaccessibility of the source population size for national security reasons. Post-traumatic stress disorder was assessed using the “post-traumatic stress disorder checklist-5 (PCLS-5) scale. Results: A total of 305 subjects participated in the survey. Males dominated 90.2%. The most represented corps was the Republican Police (41.6%), most of whom were non-commissioned officers (46.6%). The majority count between 11 and 20 years of service (48.9%), with 2 to 5 missions completed (67.5%). The calculated prevalence of post-traumatic stress disorder was 11.8%, based on the post-traumatic stress disorder checklist-5 (PCL-5). Of the 36 respondents with post-traumatic stress disorder, 20 (55.6%) had experienced an armed attack, 25 (69.4%) had witnessed a violent death, 18 (50.0%) had witnessed the agony of a colleague, 15 (41.7%) had been exposed to a fire or explosion, while 26 (72.2%) had been traumatized by physical and/or verbal aggression. 5 (13.9%) had consulted a specialist psychiatrist, while 6 (16.7%) were on medication and 26 (72.2%) used sport as a means of maintaining physical and mental health.

We present a new iterative reconstruction algorithm to improve the algebraic reconstruction technique （ART） for the Single-Photon Emission Computed Tomography. Our method is a generalization of the Kaczmarz iterative algorithm for solving linear systems of equations and introduces exact and implicit attenuation correction derived from the attenuated Radon transform operator at each step of the algorithm. The performances of the presented algorithm have been tested upon various numerical experiments in presence of both strongly non-uniform attenuation and incomplete measurements data. We also tested the ability of our algorithm to handle moderate noisy data. Simulation studies demonstrate that the proposed method has a significant improvement in the quality of reconstructed images over ART. Moreover, convergence speed was improved and stability was established, facing noisy data, once we incorporate filtration procedure in our algorithm.

Introduction: Cardiovascular disease represents a major public health burden worldwide. Research and management of risk factors contribute to the prevention of these diseases. The aim of this study was to assess the prevalence of dyslipidemia in the biochemistry unit of the Charles De Gaulle Pediatric University Hospital (CHUP-CDG) in Ouagadougou. Material and Methods: This was a descriptive and analytical cross-sectional study, with retrospective data collection from January 1, 2020 to December 31, 2022. Patients of all ages who performed a lipid panel in the CHUP-CDG biochemistry unit during the study period have been included. Results: A total of 2872 patients have been included. The mean age of the study population was 27.72 ± 19.51 years and the M/F sex ratio was 0.81. Among the patients, 22.84% had at least one dyslipidemia. The prevalences of hypercholesterolemia, hypo-HDL cholesterolemia and hyper-LDL cholesterolemia were 11.57%, 49.19% and 57.50% respectively. Hypertriglyceridemia and mixed hyperlipidemia were present in 9.04% and 2.08% of patients. Hypercholesterolemia was significantly more frequent in the female sex (p = 0.0077);hyper-LDL cholesterolemia (p = 0.0255) and mixed hyperlipidemia (p Conclusion: The relatively high prevalence of dyslipidemia in the study indicates a worrying situation. It would therefore appear essential to extend the search for risk factors nationwide, particularly those that can be modified, in order to reduce morbidity and mortality linked to cardiovascular disease.

Objective: The aim of the present study was to investigate the psychic repercussions of sexual assault among female students in Parakou in 2023. Methods: Descriptive cross-sectional study conducted from December 2022 to July 2023 among all students at the University of Parakou. The sampling technique was stratified non-proportional at two levels. The dependent variable was self-reported sexual assault. The psychopathological repercussions linked to sexual assault and explored in these students were: post-traumatic stress disorder assessed with the Post Traumatic Stress Disorder Checklist-5 (PCL-5) scale;and current depression screened with the Patient Health Questionnaire-9 (PHQ-9) scale. Results: A total of 376 female students from the University of Parakou meeting the inclusion criteria were surveyed. The average age of the subjects surveyed was 20.56 ± 2.46 years, with extremes of 16 and 32 years. A predominance of subjects under 25 was observed. The prevalence of sexual assault among female students at the University of Parakou was 10.63%. The types of aggression suffered were mostly rape (18 people;45%) and sexual touching (16 people;40%), and the aggressors were mainly friends/boyfriends (13;32.5%), family members (12;30.0%) and people from the house/neighborhood (9;22.5%). Psychological repercussions included depression in 72.5% (29) of cases, with mild depression in 30% (12), moderate depression in 37.5% (15) and severe depression in 5% (2). Anxiety disorders were present in 27.50% (11) of victims. The risk factors associated with sexual assault in these students were gravidity (p = 0.014;OR = 15.32), unhappy life events (p = 0.01;OR = 17.24), and age of first sexual intercourse (p = 0.016;OR = 4.608). Conclusion: One in ten female students in Parakou has been sexually assaulted. Once again, preventive action through effective sex education is a means of fighting the problem that should be prioritized for every girl and boy from an early age. Psychological s

Introduction: Also known as maternal burnout syndrome, maternal burnout is a state of physical, emotional and mental exhaustion generated by prolonged stress in the family environment. It is experienced by women in their role as mothers. Those affected can develop psychological disorders, sleep disturbances, etc., all of which impair their day-to-day lives, and thus their maternal role. The repercussions affect both the child and other family members. Objective: The aim of the present study was to investigate maternal burnout among female users of public and private health facilities in the commune of Parakou in 2023. Methods: Descriptive cross-sectional study was conducted from December 2022 to July 2023 among all mothers using public and private health facilities in the commune of Parakou. All healthy mothers with at least one biological or adoptive child fully dependent on them and living at home, who came for a consultation in one of the health facilities or for an appointment at the Expanded Program on Immunization (EPI) and gave their free and informed consent. Sampling was done for non-exhaustive convenience were included in the study. Burnout was assessed using the Parental Burnout Assessment (PBA) scale. Results: A total of 888 mothers meeting the inclusion criteria were surveyed. The prevalence of burnout calculated using the Parental Burnout Assessment (PBA) scale was 6.19%. The risk factors for maternal burnout were poor relationships with family and friends (OR = 8.90;p = 0.045), moderate (OR = 11.71;p = 0.020) and severe depression (OR = 40.85;p = 0.001), followed by the presence of repeated nocturnal awakening (OR = 5.14;p = 0.014). Conclusion: This is a subject that is almost never discussed in African society, but whose reality is revealed by the present study, which provided statistical data on maternal burnout. From now on, the risk of burnout will no longer be discussed solely in the family context. It will also need to be explored within the fam

Lithium-ion batteries are a key technology in today＇s world and improving their performances requires, in many cases, the use of cathodes operating above the anodic stability of state-of-the-art electrolytes based on ethylene carbonate （EC） mixtures. EC, however, is a crucial component of electrolytes, due to its excellent ability to allow graphite anode operation-also required for high energy density batteries-by stabilizing the electrode/ electrolyte interface. In the last years, many alternative electrolytes, aiming at allowing high voltage battery operation, have been proposed. However, often, graphite electrode operation is not well demonstrated in these electrolytes. Thus, we review here the high voltage, EC- free alternative electrolytes, focusing on those allowing the steady operation of graphite anodes. This review covers electrolyte compositions, with the widespread use of additives, the change in main lithium salt, the effect of anion （or Li salt） concentration, but also reports on graphite protection strategies, by coatings or artificial solid electrolyte interphase （SEI） or by use of water-soluble binder for electrode processing as these can also enable the use of graphite in electrolytes with suboptimal intrinsic SEI formation ability.

Introduction: In serodiscordant couples, sharing serostatus is a crucial step in the HIV risk management process. The aim of this study was to determine the prevalence and factors associated with serostatus sharing among HIV serodiscordant couples in the city of Parakou. Setting and methods: This study was carried out in the city of Parakou, capital of northern Benin. It was a descriptive, analytical cross-sectional study with non-probability sampling for convenience. Socio-demographic data, as well as data on antecedents, behaviours, social and marital life, were collected using a questionnaire gave to the participants. Clinical and therapeutic data were collected from patients’ medical records and follow-up charts. Data were analyzed and processed using R 4.3.1 software. The significance level was set at 5%, and logistic regression was used to identify potential predictors of shared serostatus among serodiscordant couples in the city of Parakou in 2022. Results: A total of 299 participants in long-term serodiscordant relationships were included in our study. The average age of the subjects was 37.55 ± 10.25 years. Women were the infected partner in 80.27% of cases. The most common level of education was secondary (33.45%). Most respondents (230 subjects, 76.92%) were married. The average duration of the couple’s relationship was 121.68 months ± 96.32. The most frequent screening circumstances were: Prevention of mother-to-child transmission (PMTCT) (50.84%) and hospital screening (26.09%). The infected partner shared his or her serostatus with his or her spouse in 47.83% of cases. Potential predictors of serostatus sharing within the couple were: marital status (p Conclusion: The sharing of serostatus within serodiscordant couples needs to be managed in a way that takes into account the social and marital characteristics of the couple.

Objectives: Atlantoaxial dislocation remains a rare and serious condition with a high preoperative and postoperative morbidity and mortality. Its successful surgical management is still challenging and gratifying for neurosurgeons. Several technics have been described such as wiring, trans articular screwing, C1C2 screwing with plate and screw introduced by Goel et al., and modified by insertion of polyaxially screw and rod many years later by Harms. Unavailability and expensiveness of upper cervical spine instrumentation device led us to C1C2 Wiring resulting in a good outcome. Finally, a quadriplegic patient with a more comfortable financial condition had ordered devices from abroad and benefit for Goel and Harms screwing technique and improved dramatically from ASIA A to ASIA E. Material and methods: This is a retrospective study of patients managed in our department by a same neurosurgeon from January 2019 to April 2024. Results: We defined 6 men and 1 woman with an average age of 33 years. Unrestrained driver in a rollover motor vehicle accident was most common. Only one patient was neurologically intact on admission. Neurovegetative disorders were noticed in one patient. Dislocation was associated to a fracture of the dens in two patients. Three patients have been successfully operated with remarkable outcome, mostly from ASIA A to E. Conclusion: C1C2 dislocation is a serious condition and C1C2 Wiring represents an effective and cheaper technic. Therefore, this technic should deserve consideration above all in low incomes countries when screwing devices are not available. Seatbelt should be demanded for motor vehicle drivers and passengers.
