Different tests are used to evaluate the aerobic capacity of a person. This study aims to investigate the gender and Body Mass Index (BMI) difference in aerobic capacity measured by using shuttle and Spartacus test. The study was conducted on 230 high school students (135 girls and 95 boys) followed their study in public establishment in kenitra city (Morocco). All participants were classified according to their gender (male vs. female) and their BMI (normal weight vs. overweight-obese) and performed the both test of shuttle and Spartacus. Running speed at the last completed stage, run time, maximum heart rate (max HR) max HR and perceived exertion were measured and analyzed. For each test, VO2max was estimated by using the proposed equation. There was significant BMI difference in the measured parameters (p<0.001). Difference in VO2max between male and female remained significant with high-speed level in boys. A significant difference between males and females (p < 0.001) was observed in shuttle test. Participants with normal weight or physical activity had good aerobic capacity. Compared to the Shuttle test, the Spartacus provides a 11.5% higher final speed (11.2 vs. 9.7km/h) and a total test time 2.3 times longer (11.3vs. 4.9 min) (p < 0.001). Our study underlines the interest of the Spartacus test and is preliminary. Indeed, these results must now be replicated in a larger sample of obese adolescents [ABSTRACT FROM AUTHOR]

Distance training or distance learning has experienced a boom in recent years in several regions of the world. It follows from this interest that the emergence of distance learning has been remarkably advocated by higher education institutions and less and less at the secondary and college levels where face-to-face training is becoming essential. However, during the period of health crisis due to Covid-19, distance education had established itself as a new alternative mode for face-to-face education for all levels of education, and for all subjects combined. Physical and sports education (PSE) is no exception to this change. In this context, the discipline EPS has sparked a debate on the modalities of engagement of teachers of EPS to participate in distance education given the almost practical nature of the subject. Faced with this problem, EPS teachers (high school and college) found themselves forced to formalize educational content and transmit it on various media. This study contributes to the identification of the degree of commitment of PE teachers to ensure the sustainability of learning and to determine the obstacles encountered in this operation qualified as urgent. This study saw the participation of 166 teachers in two levels of secondary and college education through three regional academies in Morocco. The results showed both the lack of communication between the inspectors of the EPS and the teachers of the subject, and the coordination between the teachers within the teaching units.  , La formation à distance ou l’apprentissage à distance connait son plein essor ces dernières années dans plusieurs régions du monde.

Cependant, pendant la période de crise sanitaire à cause du Covid-19, l’enseignement à distance s’était imposé comme un nouveau mode alternatif pour le présentiel pour tous les niveaux d’enseignement, et pour toutes les matières confondues.

Cette étude contribue à l’identification du degré d’engagement des enseignants d’EPS pour assurer la durabilité des apprentissages et de déterminer les entraves rencontrées dans cette opération qualifiée d’urgente. Cette étude a vu la participation de 166 enseignants dans deux niveaux d’enseignements secondaire et collégial à travers trois académies régionales au Maroc. Les résultats ont montré à la fois l’absence de la communication entre les inspecteurs de l’EPS et les professeurs de la matière, et la coordination entre les professeurs au sein des unités pédagogiques.

Medicine - Abstract
Abstract Background Vinblastine (VBL) is the standard treatment for systemic Langerhans cell histiocytosis (LCH), but little is known about its efficacy in central nervous system (CNS) mass lesions. Methods A retrospective chart review was conducted. Twenty patients from the French LCH Study Group register met the inclusion criteria. In brief, they had CNS mass lesions, had been treated with VBL, and were evaluable for radiologic response. Results The median age at diagnosis of LCH was 11.5 years (range: 1-50). Intravenous VBL 6 mg/m2 was given in a 6-week induction treatment, followed by a maintenance treatment. The median total duration was 12 months (range: 3-30). Eleven patients received steroids concomitantly. Fifteen patients achieved an objective response; five had a complete response (CR: 25%), ten had a partial response (PR: 50%), four had stable disease (SD: 20%) and one patient progressed (PD: 5%). Of interest, four out of the six patients who received VBL without concomitant steroids achieved an objective response. With a median follow-up of 6.8 years, the 5-year event-free and overall survival was 61% and 84%, respectively. VBL was well-tolerated and there were no patient withdrawals due to adverse events. Conclusion VBL, with or without steroids, could potentially be a useful therapeutic option in LCH with CNS mass lesions, especially for those with inoperable lesions or multiple lesions. Prospective clinical trials are warranted for the evaluation of VBL in this indication.

Background Mediastinal involvement (MI) in Langerhans cell histiocytosis (LCH) has been rarely reported. Here, we describe the clinical, radiological, and biological presentation, and the outcome of childhood LCH with MI. Method From the French LCH register, which includes 1,423 patients aged less than 18 years, we retrieved the medical charts of patients with mediastinal enlargement detected on chest X-rays. Results Thirty-seven patients were retrieved, including 18 males; median age of diagnosis was 0.7 years, and median follow-up time was 6.2 years. The prevalence of MI varied with the age at diagnosis, ranging from 7% below 1 year old to less than 1% at >5 years. Thirteen cases (35%) were diagnosed because of MI-related symptoms, including respiratory distress (N = 4), superior venous cava syndrome (N = 2), and/or cough and polypnea (N = 10). CT scans performed in 32 cases at diagnosis showed tracheal compression (N = 5), cava thrombosis (N = 2), and/or calcification (N = 16). All patients presented multi-system disease at LCH diagnosis, and 35/37 were initially treated with vinblastine and corticosteroids. Death occurred in five cases, due to MI (N = 1) or hematological refractory involvement (N = 4). The overall 5-year survival was 87.1%, and immunodeficiency was not detected as a sequel. Conclusions MI in LCH mainly occurs in young children, and diagnosis was based on CT showing thymus enlargement and calcifications.

- Abstract
Heterozygous mutations of the gene encoding neutrophil elastase (ELA2)have been associated with cyclic neutropenia (CN) and severe congenital neutropenia (SCN). To date, 30 different mutations have been reported, but no correlation has been found with the degree of neutropenia. To address this issue, we analyzed the clinical, hematologic, and molecular characteristics of 81 unrelated patients with SCN (n = 54) or CN (n = 27). We identified mutations in 31 patients, two thirds of whom had sporadic forms. Familial cases were consistent with dominant inheritance. Seventeen novel mutations were identified, showing that the mutational spectrum encompasses not only the region encoding the mature enzyme but also the prodomains and promoter region. Genotype-phenotype analysis strongly suggested that ELA2mutations correlate with more severe expression of neutropenia, specifically in patients diagnosed with SCN. This study underlines the importance of ELA2molecular screening to identify patients who may be at particular risk of severe bacterial infections and/or acute myeloid leukemia/myelodysplasia. By phenotypic analysis of affected relatives and carriers of the same ELA2mutations, we showed that the expression of neutropenia in CN and SCN may be either homogeneous or variable according to the type of mutations, suggesting different pathogenetic mechanisms.

- Abstract
Different tests are used to evaluate the aerobic capacity of a person. This study aims to investigate the gender and Body Mass Index (BMI) difference in aerobic capacity measured by using shuttle and Spartacus test. The study was conducted on 230 high school students (135 girls and 95 boys) followed their study in public establishment in kenitra city (Morocco). All participants were classified according to their gender (male vs. female) and their BMI (normal weight vs. overweight-obese) and performed the both test of shuttle and Spartacus. Running speed at the last completed stage, run time, maximum heart rate (max HR) max HR and perceived exertion were measured and analyzed. For each test, VO2max was estimated by using the proposed equation. There was significant BMI difference in the measured parameters (p<0.001). Difference in VO2max between male and female remained significant with high-speed level in boys. A significant difference between males and females (p < 0.001) was observed in shuttle test. Participants with normal weight or physical activity had good aerobic capacity. Compared to the Shuttle test, the Spartacus provides a 11.5% higher final speed (11.2 vs. 9.7km/h) and a total test time 2.3 times longer (11.3vs. 4.9 min) (p < 0.001). Our study underlines the interest of the Spartacus test and is preliminary. Indeed, these results must now be replicated in a larger sample of obese adolescents.

- Abstract
Introduction: tuberculosis is a public health problem in Morocco. This study aims to examine the epidemiological profile as well as the evolutionary and diagnostic features of tuberculosis in Settat, Morocco., Methods: we conducted a retrospective descriptive and analytical study of data from the medical records of TB patients managed at the Diagnostic Centre for Tuberculosis and Respiratory Diseases in Settat, Morocco from 1
st January 2015 to 31 December 2019., Results: we identified 1270 cases of tuberculosis. Lung involvement was more common than extrapulmonary involvement. Ganglionic tuberculosis mainly occurred in patients with extrapulmonary tuberculosis. Severe forms included tuberculous meningitis (10 cases) and miliary tuberculosis (10 cases). Diagnosis was bacteriologically confirmed in the majority of patients (84.09%). Extreme ages and female sex were mainly affected by extrapulmonary tuberculosis. Recovery was reported in 35.12% of patients and its rate was higher in pulmonary TB patients than in extrapulmonary TB patients (62.18% vs 0.37%; P<0.001). Patients with pulmonary tuberculosis (19.33% vs 10.81%; P<0.001) were mainly lost to follow-up. Death occurred to almost the same extent in patients with pulmonary and extrapulmonary tuberculosis (2.52% vs. 2.56%)., Conclusion: efforts on all fronts are still needed if the country is to achieve the goal of eliminating TB by 2030., Competing Interests: Les auteurs ne déclarent aucun conflit d´intérêts., (Copyright: Mohamed Chahboune et al.)- Published

- Abstract
Background and Objectives: The two main complications of severe chronic neutropenia are fatal sepsis and myelodysplasia/acute leukemia (MDS/AL). Granulocyte colony-stimulating factor (G-CSF) therapy has significantly reduced the frequency and severity of infections, but its possible influence on the risk of malignancy is not known., Design and Methods: The French Severe Chronic Neutropenia (SCN) Registry has prospectively collected data since 1994 on 231 patients with various forms of SCN, namely severe congenital neutropenia (n=101), cyclic neutropenia (n=60), glycogen storage disease type Ib (GSDIb) (n=15) and Shwachman-Diamond syndrome (SDS)(n=55). The median overall follow-up is 11.1 years. Parameters of exposure to G-CSF therapy, such as the time averaged dose, follow up after first use of G-CSF, and the cumulative dose, have been recorded., Results: Eight septic deaths occurred, of which 6 among patients with severe congenital neutropenia and 2 in patients with cyclic neutropenia; none of these 8 patients was receiving G-CSF therapy. No septic deaths occurred during G-CSF therapy. Thirteen cases of MDS/AL were recorded. The cumulative incidence of MDS/AL was 2.7% (SD 1.3%) at 10 years and 8.1% (SD 2.7%) at 20 years., Interpretation and Conclusions: Risk factors for MDS/AL were the diagnostic category, the severity of neutropenia, younger age at diagnosis, and strong exposure to G-CSF. MDS/AL only occurred in patients with severe congenital neutropenia and SDS. Owing to their particular susceptibility to infections, patients with severe congenital neutropenia had the strongest exposure to G-CSF; the risk of leukemia increased with the degree of G-CSF exposure in this subgroup.
