Anthropometric status and body image perception among Moroccan university students

BackgroundUniversity students aged between 18 and 25 undergo several physical changes as a result of transition from adolescence to adulthood. Students do not always accept those changes and sometimes develop dissatisfaction towards their figures. In such cases, it is still not clear how actual body weight status can be affected by socio-cultural factors such as body image perception. The objective of this study was to determine the link between anthropometric status and body image perception among university students.MethodsTwo hundred and forty six (246) university students from the Faculty of Sciences and Technologies within the Beni Mellal-Khenifra region in Morocco, aged 20–24 years were interviewed using face-to-face questionnaires. Anthropometric measurements and Body Mass Index were collected. Body image perception was assessed by Figure Rating Scale, and body size dissatisfaction was calculated as Feel minus Ideal Discrepancy (FID). Data were described using means and proportions. The Student t-test and the chi-square test have been used to assess the statistical significance of group differences.ResultsUnderweight students represented 16.7% of the investigated sample, while 11.4% suffered from overweight and obesity, higher in females students (14.4%) than in males (7.9%). Regarding body image perception, 43.9% of participants considered themselves underweight; whereas only 4.2% considered themselves overweight with no significant differences related to gender. Of note, the total prevalence of body image dissatisfaction was around 69.8%. Finally, among overweight/obese students, 88.9% of females and 71.4% of males expressed the wish to become thinner while 28.6% of the overweight/obese males wanted to get heavier.ConclusionThe results of this study indicate a high rate of body image dissatisfaction and a tendency of participants to underestimate their body weight. This behavior may be a reflection of a real influence of social and psychological factors occurring during this critical period and may make university students vulnerable to many risk-taking behaviors. Thus, there is a need for suitable interventional programs and innovative strategies to ensure the understanding of the health consequences of overweight and obesity and to prevent associated comorbidities.     

Streptococcus pneumoniae carriage among febrile children at the time of PCV-10 immunization in pediatric emergencies at Mohammed VI University Hospital Centre in Marrakesh (Morocco)

ObjectivesIn Morocco, 13-valent pneumococcal conjugated vaccine (PCV) was introduced in the childhood immunization program in October 2010 and changed to PCV-10 in July 2012. The purpose of this study was firstly to determine the prevalence of pneumococcus carriage in a population of febrile infants in Marrakesh and secondly, to investigate the risk factors for carriage and the distribution of circulating serotypes.Material and methodsThis prospective study was conducted from February to June 2017, in the pediatric emergency department of the Mother and Child Hospital of Mohammed VI University Hospital Centre (UHC) in Marrakesh. At total of 183 febrile infants, aged 2–18 months, were enrolled in this study and were swabbed for nasopharyngeal carriage. Pneumococci were cultured, identified, serotyped, and tested for penicillin susceptibility. Demographic data and risk factors for carriage were collected. The statistical analyses performed were the following: the analysis of the risk factors using logistic regression, the estimation of serotype diversity with the Simpson index, and the Chi² test to compare serotype distribution in the prevaccination (a cohort of 660 healthy children, less than 2 years old, in the Marrakesh region, in 2008–2009) and postvaccination periods.ResultsThe prevalence of Streptococcus pneumoniae carriage was 68.3%. Of the 183 infants enrolled in this study, 111 had received at least one dose of PCV-10. Colonization by vaccine serotype among febrile children was related to incomplete vaccination status. In total, vaccine serotypes accounted for 6.4% (n = 8): 19F (n = 2), 1 (n = 2) and one strain for each of the following serotypes: 14, 23F, 6B, and 9 V. Non-vaccine and nontypeable strains presented 63.2% and 23.2%, respectively, with dominance of serotypes 6A (6.4%), 15A/15F (5.6%), 20, 22F/22A, 23B, and 11A/11D with a prevalence of 3.2%. The rate of pneumococcus strains with reduced susceptibility to penicillin was 33.6%, of which 90.2% were non-vaccine serotypes and nontypeable strains. Serotype diversity increased in the postvaccination period and the effectiveness of PCV-10 against vaccine serotypes was estimated at 89.6%.ConclusionAn important change in the distribution of vaccine and non-vaccine serotypes was observed after the introduction of the PCVs. In fact, the prevalence of vaccine serotypes decreased significantly while non-vaccine serotypes emerged. These results underscore the importance of maintaining close and prolonged surveillance of serotype distribution to monitor the dynamics of nasopharyngeal pneumococcal carriage.

An update on epidemiology,diagnosis & management of NMO-SD in the tertiary neurology department of Marrakech (Morocco)

IntroductionNeuromyelitis optica (NMO) and NMO spectrum disorders (NMO-SD) are inflammatory demyelinating diseases of the central nervous system. There are few epidemiological studies devoted to NMO, especially in Africa and the Middle East, but individual cases and series have been reported from many countries across the African continent.ObjectivesTo describe the epidemiology, diagnosis, and management of NMO patients followed at the Mohammed VI University Hospital of Marrakech.Patients and methodsThis was a hospital-based retrospective study of 52 patients with NMO diagnosed and followed at the Neurology department of the University Hospital of Marrakech from 2004 to July 2019. The 2006 diagnostic criteria of NMOSD were used for patients admitted before 2015 for inflammatory disease of the central nervous system and the 2015 diagnostic criteria of NMO-SD for all patients thereafter. Collected data were analysed using SPSS software.ResultsThe study concerned 52 patients, 18 males and 34 females. Median age at disease onset was 32.5 years (range 7–55). Mean time between symptom onset and diagnosis of NMO was nine months 18 days (range 7 days to 4 years). In most patients, manifestations included visual acuity, tetraparesis, and sensorial disorders. Refractory vomiting and hiccup were noted in the first attack in 19% of patients. Two patients had hypersomnia and polyphagia, and one had been treated for depression ten months before the development of severe tetraplegia. Magnetic resonance imaging did not show any brain lesions in 29% of patients. Cervical myelitis extending to more than three vertebrae was found in 60% of patients. AQP4-antibody assay was performed only in 57.7% of patients, and was positive in 38.4%; anti-MOG was positive in four anti-AQP4 seronegative patients. Management strategies for NMO-SD included methylprednisolone pulses (70% of patients), plasmapheresis (25%), and rituximab (since 2017) for 46%. Outcome was favourable in 40% of patients and has remained stable in 50% of them.ConclusionAnti-NMO assays, made available during the last five years with the help of The Guthy-Jackson Charitable Foundation, have led to a clear jump in the number of cases diagnosed. Major advances in the field of epidemiology, imaging, and pathophysiology of NMO-SD have led to improved patient care and outcome.     

Profil de l’hémogramme et intérêt de la mesure de l’hémoglobine pré-don chez des donneurs de sang de la région Nord-Ouest du Maroc

Background

Blood donation in Morocco and more particularly in the northwest region is carried out without prior determination of the pre-donation hemoglobin. In addition, we note the lack of scientific research that reports data on the red blood cells, leukocytes and platelet lines in donated blood at the regional or even national level.

New Invertebrate Vectors of Okadaic Acid from the North Atlantic Waters—Portugal (Azores and Madeira) and Morocco

Okadaic acid and its analogues are potent phosphatase inhibitors that cause Diarrheic Shellfish Poisoning (DSP) through the ingestion of contaminated shellfish by humans. This group of toxins is transmitted worldwide but the number of poisoning incidents has declined over the last 20 years due to legislation and monitoring programs that were implemented for bivalves. In the summer of 2012 and 2013, we collected a total of 101 samples of 22 different species that were made up of benthic and subtidal organisms such echinoderms, crustaceans, bivalves and gastropods from Madeira, São Miguel Island (Azores archipelago) and the northwestern coast of Morocco. The samples were analyzed by UPLC-MS/MS. Our main objective was to detect new vectors for these biotoxins. We can report nine new vectors for these toxins in the North Atlantic: Astropecten aranciacus, Arbacia lixula, Echinaster sepositus, Holothuria sanctori, Ophidiaster ophidianus, Onchidella celtica, Aplysia depilans, Patella spp., and Stramonita haemostoma. Differences in toxin contents among the species were found. Even though low concentrations were detected, the levels of toxins that were present, especially in edible species, indicate the importance of these types of studies. Routine monitoring should be extended to comprise a wider number of vectors other than for bivalves of okadaic acid and its analogues.
