[Acquired bone marrow aplasia in children and young adults under the age of 30: Experience of the Pediatric Hematology and Oncology Department of the 20 August Hospital, Casablanca]. / Aplasie médullaire acquise de l'enfant et de l'adulte jeune de moins de trente ans : expérience du service d'hématologie et d'oncologie pédiatrique de l'hôpital 20 Août de Casablanca.

Bone marrow aplasia is a rare and serious hematologic disorder. Although benign, it is a hematologic disorder whose prognosis can be poor and whose spontaneous development can be fatal. Treatment is long, difficult and costly. In developing countries, the mortality rate is high due to the difficulties of therapeutic management, both supportive and specific. We conducted a retrospective study of 92 cases of AM identified in the Pediatric Hematology and Oncology Department of the 20 Août University Hospital in Casablanca over a 10-year period (January 2010-January 2020). In this work, we present an overview of the situation and highlight the difficulties encountered in the management of AM in the Pediatric Hematology and Oncology Department of the University Hospital of Casablanca. In our study, the mean age was 19 years, ranging from 3 months to 29 years, with a peak in the 15-20 age group. The sex ratio (M/F) was 2.06, with a male predominance of 67%. In our series, only 35% of patients had complete bone marrow failure. An anemic syndrome was present in 92% of patients, and hemorrhagic and infectious syndromes were present in 70% and 41% of patients, respectively. The median time from diagnosis to treatment was 82 days. According to the Camitta score, 31% of our patients had mild AM, 41% had severe AM, and 28% had very severe AM. After etiologic evaluation, we concluded that 90% of the patients had idiopathic bone marrow aplasia, 2% had constitutional bone marrow aplasia, and 8% of the patients were suspected to have secondary bone marrow aplasia: post-hepatitis (3 cases), toxic (2 cases), drug-induced (1 case), and aplastic PNH (1 case). Mortality in the first three months after diagnosis was 21%. Sixty-nine percent of our patients received specific treatment: 28 were treated with cyclosporin (CIS) alone as first-line therapy, 20 received a combination of antilymphocyte serum (ALS) and cyclosporin, 2 received hematopoietic stem cell transplantation (HSCT), while 3 were treated with androgens alone. The overall response rate was 30% with CIS, 42% with ALS+CIS and 100% with HSCT. In our study, the overall death rate was 44%, while the one-year survival rate was 40%. It is important to note that septic shock was the leading cause of death (53% of deaths), followed by hemorrhagic shock (24%). This highlights the lack of hemodynamic resuscitation and symptomatic treatment. Our multivariate study defined the following risk factors as predictive of worse survival: age greater than 16 years (RR: 3.28; CI: 1.29-8.33; P=0.012), PNN less than 200 or very severe bone marrow aplasia (RR: 3.01; 1.1-8.08; P=0.028), and failure to receive any specific treatment (RR: 4.07; 1.77-9.35; P=0.0003). The high overall mortality in our series was due to several factors: inaccessibility to effective therapies, delayed diagnosis, failure to initiate specific treatment, inadequate symptomatic treatment, and geographical and financial inaccessibility.

Prevalence and determinants of frailty among the elderly in the province of Essaouira, Morocco.

Introduction: Morocco is no exception to the global phenomenon of an ageing population. The number of people aged 60 and over rose from one million to 4.5 million between 1970 and 2022. In terms of health, 64.4% of Moroccan seniors are affected by at least one chronic disease, and almost a third suffer from disability. We aimed to estimate the prevalence and identify the factors associated with frailty among the elderly in the Essaouira province of Morocco. Methods: a descriptive and analytical cross-sectional survey of 384 people aged 65 and over attending health centres in Essaouira province was conducted between March 2022 and January 2023. Data were collected using a self-administered questionnaire. The Fried phenotype was used to assess frailty in the participants. Results: according to Fried's phenotype, 46.4% of the elderly were frail. Multivariate analyses showed that frailty was associated with family type [OR=1.9; 95% CI 1.4-2.6], professional activity [OR=2.2; 95% CI 1.2-3.9], financial difficulties [OR=1.7; 95% CI 1.1-2.8] and undernutrition [OR=2.9; 95% CI 1.7-4.8]. Conclusion: implementing a screening strategy and speeding up the process of generalising social protection are actions that will make it possible to reduce the prevalence of frailty among the elderly, prevent its complications and act on its main determinants in Morocco.

Epidemiological profile of patients attending the maxillofacial prosthodontics unit at Ibn Sina University Hospital in Rabat, Morocco: a cross-sectional study.

Introduction: the present study aimed to establish an epidemiological profile of patients consulting the unit of maxillofacial prosthodontics in Rabat. Results deriving from this study will help enhance the quality of patient care in our center and can also serve as a comparison tool with other maxillofacial teams around the world. Methods: during 11 months all patients consulting the unit of maxillofacial prosthodontics in our center were included. We opted for a questionnaire with 3 variables: socio-demographics, clinical examination data, and the type of prosthetic treatment adopted. The study was conducted in the Department of Removable Prosthodontics in the Center of Consultation and Dental Treatment of Rabat Morocco (CCDTR) from September 2020 to July 2021. Results: the study population consisted of 91 patients, with a majority of male patients at 53% (n=48). During our study period, the proportion of patients under one-year-old was predominant, accounting for 38.4% (n=35) of the total sample. Among the patients in the sample, 72.5% (n=66) had no profession, while 66% (n=60) had a low income. Regarding medical insurance, the majority of our patients, 85.5% (n=78), were covered by Public Health Insurance for the Low-income Population (PHILP). Among the total sample, 57.1% (n=52) consulted for a combination of pain function and aesthetics. Additionally, 61.5% (n=56) were referred by teaching hospitals. For the type of oro-facial defect, 52.7% (n=48) of the sample consisted of newborns with congenital facial cleft. Out of the 91 patients, 36 had maxillofacial tumors, with 47.6% (n=17) of them presenting squamous cell carcinoma. Furthermore, 63.7% (n=58) of the prosthetic treatments adopted involved presurgical orthopedic treatments for newborns with facial cleft. Conclusion: the study on the epidemiological profile of patients attending the maxillofacial prosthodontics unit at Ibn Sina University Hospital in Rabat, Morocco provides important insights. The findings highlight the predominance of male patients and the prevalence of oro-facial defects in newborns. Socioeconomic factors, such as low income and lack of profession, are significant considerations. The majority of patients are covered by the PHILP, indicating the importance of medical insurance. These findings contribute to improving healthcare planning and specialized care for this patient population.

Cardiovascular risk factors in Moroccan women: systematic review and meta-analysis.

BACKGROUND: Cardiovascular diseases (CVD) are the major cause of disability and premature death. This is due to the ascending trend of consuming an unhealthy diet and obesity which increases the risk of hypertension and type 2 diabetes mellitus. The main aim of this review was to fill the knowledge gap by providing an up-to-date overview of the prevalence of CVD risk factors among women and to estimate the pooled prevalence among adolescent and pregnant women in Morocco. METHODS: The review included original cross-sectional studies reporting the prevalence of CVD risk factors in Moroccan women aged ≥ 15 years, published between January 2008 and December 2022. The databases searched included MEDLINE, Scopus, Web of Science, Google Scholar and national government publications (PROSPERO ID: CRD42023426809). RESULTS: Initially, 1471 articles were identified, and 76 studies were included. The most commonly reported CVD risk factor was obesity (reported in 56 studies), the prevalence of obesity varies according to the age groups of women with the rate being particularly high in urban women aged ≥ 35 years (ranging of 14-44.9%). Followed by diabetes (ranging from 7.2 to 12.6%) with a high rate in menopausal women. Hypertension prevalence ranged from 29.8 to 39.29%. Among adolescents, the overall prevalence of obesity was 3.15% (95% CI: 2.6%, 3.7%) and the prevalence of physical inactivity was 56.5% (95% CI: 36.9 - 76%). Among pregnant women, the overall prevalence of obesity was 26.8% (95% CI: 15.5 - 38.2%). Gestational diabetes and hypertension were 15.2% (95% CI: 6.3 - 24.1%) and 7.07% (95% CI: 2.5 - 11.6%), respectively. CONCLUSION: This review highlights the significant burden of CVD risk factors among Moroccan women, with a high prevalences of diabetes, obesity, hypertension. The prevalences of these risk factors varies with age, being notably higher in older age groups. These findings underscore the need for targeted public health interventions to address these risk factors. Future research should focus on longitudinal studies and standardized assessment tools to enhance the robustness of prevalence estimates and inform effective prevention strategies.

Performance evaluation of the national tuberculosis control program 2016-2020: Souss-Massa region, Morocco.

BACKGROUND: Tuberculosis constitutes a public health problem in Morocco. In an environment where results-based management and the evaluation of public policies become an imperative; the evaluation of the performance of the national tuberculosis control program finds its interest. OBJECTIVES: This study aims to analyze the performance of the tuberculosis control program in the Souss Massa region, based on the systemic approach model over a five-year period 2016-2020. METHODS: This is a descriptive secondary data analysis carried out in the Souss-Massa region in southern Morocco over a five year period 2016-2020. Data collection was carried out through the health information system of the NTCP and the various periodic reports produced by the primary health care establishments and diagnostic centers for tuberculosis and respiratory diseases, the delegations and the regional health directorate of the Ministry of Health. RESULTS: The incidence of tuberculosis has fluctuated between 63 and 72 cases/100,000 inhabitants; the average number of cases detected is 1871 cases per year; the survey completion rate is 57.10%; the therapeutic success rate varies between 82% and 89%, the treatment failure rate varies between 0.62% and 2.32%; the death rate varies between 0.63% and 2.92%; the failure rate for tuberculosis/HIV cases is between 3.10% and 6.09%. CONCLUSIONS: The results of the program tracer indicators at the level of the Souss-Massa region show that the latter combs to achieve the target objectives.

Severity of neuromeningeal tuberculosis in Morocco: a critical evaluation of epidemiological trends and treatment efficacy.

Introduction: neuromeningeal tuberculosis (NMT) is a significant public health challenge in Morocco because of its acute severity and high mortality rates. This study aims to comprehensively evaluate the epidemiological, clinical, therapeutic, and disease progression characteristics of NMT in the Kenitra province. Methods: a retrospective analysis was conducted on the medical records of patients diagnosed with NMT at the Diagnostic Center of Tuberculosis and Respiratory Diseases in Kenitra from 2014 to 2017. Results: among the 33 identified NMT cases, predominantly males (57.6%) were affected, with an age range of 4-76 years and a median age of 25 years. Extrapulmonary manifestations were prevalent, constituting 78.8% (n=26) of all cases, with meningeal localization in 45.5% (n=15) of confirmed cases. Furthermore, 9.1% (n=3) of cases were associated with unconfirmed cerebral tuberculosis (TB), and 12% (n=4) exhibited miliary TB. Familial transmission and comorbidities were identified as significant factors in disease progression. More than half of the patients received standardized antibacillary treatment during hospitalization, which lasted between 9 and 12 months. Treatment outcomes were generally positive (73%), but a 12% case fatality rate and 15% loss to follow-up were observed. Conclusion: this study highlights the complex clinical and public health challenges posed by NMT in Morocco. It emphasizes the need for improved health strategies that not only increase public awareness but also enhance the accessibility and quality of diagnostic services and treatment options.

Invasive Pneumococcal Infections Among Moroccan Children: Pneumococcal Vaccination Challenges in the Mature Vaccine Era.

BACKGROUND: Streptococcus pneumoniae, a major contributor to global morbidity and mortality, disproportionately affects children, the elderly, and immunocompromised individuals. Despite vaccination efforts, the challenge of serotype replacement highlights the ongoing struggle against invasive pneumococcal diseases (IPD) in Morocco, emphasizing the need for updated public health strategies and vaccine efficacy assessments. METHODS: This study was conducted at the Ibn Rochd University Hospital Center and the Mohammed VI University Hospital Center from 2019 to 2022, focusing on hospitalized children. It involved the analysis of 74 strains of IPD, assessing the distribution of pneumococcal serotypes and their antibiotic sensitivity in the post-vaccination era. RESULTS: The prevalence of meningitis or meningo-encephalitis was found to be 66% among the study subjects, with the most frequent serotypes being 3, 19A, 6B, 14, and 11. These serotypes varied significantly by age and location. Coverage rates for the pneumococcal conjugate vaccines, PCV-10 and PCV-13, were 20.27% and 56.75%, respectively. Notably, 43% of the strains were non-vaccine serotypes, with serotypes 3 and 19 accounting for 36% of the infections in children, indicating a lack of vaccine efficacy against these types. Additionally, 31.3% of the strains were Penicillin non-susceptible Streptococcus pneumoniae (PNSP), with 81.25% associated with non-vaccine serotypes. CONCLUSIONS: This study highlights the persistence of IPD in Moroccan children, revealing significant challenges despite vaccination efforts. With the reintroduction of PCV-13, concerns about the efficacy against non-vaccine serotypes, particularly 3 and 19A, remain. Continuous surveillance and adaptable vaccination strategies are essential to combat these serotype replacements and ensure the effectiveness of future preventive measures.

Epidemiological profile of dermatophytes at the parasitology-mycology laboratory at Mohammed VI University Hospital in Oujda.

BACKGROUND: dermatophytoses are a current fungal infection, caused by keratinophilic fungi (dermatophytes) able to invade the nails, hair and skin of humans and animals. AIM: the aim of this study was to establish the epidemiological and mycological profile of dermatophytes isolated in the parasitology-mycology laboratory of the Mohammed VI University Hospital in Oujda. METHODS: this is a 48-month retrospective study from January 2019 to December 2022.The study includes samples taken or sent to our parasitology-mycology laboratory for mycological study. A direct examination and culture were performed on each biological specimen. Species identification was based on macroscopic and microscopic colony criteria. RESULTS: in the present report we reviewed 950 mycological samples. Dermatophytes were isolated in 505 (53.15%) cases. The most common infections were tinea unguium (n=353; 69.90%), followed by tinea corporis (n=123; 5.74%) and tinea capitis (n=29; 5.98%). Trichophyton rubrum was the most frequently incriminated species. CONCLUSION: dermatophytes are the most frequent mycoses in humans. They are generally benign and often develop in a chronic and frequently recurrent pattern. Mycological examination is essential. It confirms the fungal origin and isolates the species responsible, in order to identify the source of contamination and implement an appropriate treatment.

[Addiction to psychoactive substances among resident physicians in Morocco: A multicenter cross-sectional study]. / Addiction aux substances psychoactives chez les médecins résidents au Maroc : étude transversale multicentrique.

Introduction Substance use among resident physicians is an underestimated, poorly understood, and serious problem because of its negative consequences for the health of physicians and also for the health and safety of the patients in their care. Objective To estimate the prevalence and identify factors associated with addictive behaviors among resident physicians at different university hospitals in Morocco. Method We conducted a multicenter cross-sectional descriptive and analytical study involving resident doctors from the 7 university hospital centers in Morocco. Resident doctors were invited to participate voluntarily in the study by completing an anonymous self-questionnaire created on Google Forms and sent via email. Results The questionnaire was completed by 310 resident physicians, representing 11.07% of the total population of resident physicians in Morocco. Among the participants, 16.1% (n=50) reported consuming one or more psychoactive substances, including 11.1% (n=37) for tobacco, 10% (n=31) for alcohol, and 6.1% (n=19) for cannabis. The consumption of ecstasy and cocaine was observed in 0.7% (n=2) for each substance. Additionally, 11.9% (n=37) of resident physicians had psychiatric disorders, and 3.2% (n=10) had attempted suicide at least once. The consumption of psychoactive substances among resident physicians was statistically significantly associated with the male gender (4.59 [2.20-9.57]; p=0.000), as well as with surgical specialty (0.48 [0.26-0.88]; p=0.017). Conclusion At the end of this work, we found that the use of psychoactive substances is frequent among resident doctors, which explains the need for preventive measures and appropriate management.

Adverse Effects of Gliptins in Type 2 Diabetics in Morocco.

INTRODUCTION: Gliptins are a relatively recent class of oral antidiabetic agents used in the treatment of type 2 diabetes. The aim of this study is to identify the adverse effects of gliptins in patients with type 2 diabetes, compare the tolerability of these drugs with data from the literature, and determine patients' behavior in the face of these adverse effects with a view to optimizing their management. METHODS: Our study is cross-sectional, descriptive, and analytical, involving 100 patients aged over 20 years, followed at the Endocrinology Department of the Military Hospital Mohammed V. RESULTS: The average age of the patients was 63 years, with a sex ratio F/H of 1.13. The median age of diabetes in the patients was 13 years, with an average blood glucose level of 1.64 and an average hemoglobin A1c of 8.26. The comorbidities were 30% cardiovascular disease, 25% hypertension, and 14% dyslipidemia, and 30% of patients had no comorbidities. Forth-six percent of patients reported adverse events and 54% did not report any adverse event. Twenty-eight percent of the adverse events were gastrointestinal, 18% skin disorders, 14% urinary tract infections, 12% hypoglycemia, 12% nervous system disorders, 8% airway infections, and 8% general disorders. CONCLUSION: This study shows that gliptins remain a safe option as the side effects seem fairly well tolerated by patients. Adverse events may impact patient compliance and pose a problem of adherence to treatment. Thus, it would be advantageous to develop therapeutic education for diabetic patients to detect and manage adverse effects.

Résumé Introduction:Les gliptines sont une classe relativement récente d'antidiabétiques oraux utilisés dans le traitement du diabète de type 2. Le but de cette étude est d'identifier les effets indésirables des gliptines chez les patients diabétiques de type 2, de comparer la tolérance de ces médicaments avec les données de la littérature et de déterminer le comportement des patients face à ces effets indésirables afin d'optimiser leur prise en charge.Méthodes:Notre étude est transversale, descriptive et analytique, portant sur 100 patients âgés de plus de 20 ans, suivis au service d'endocrinologie de l'hôpital militaire Mohammed V.Résultats:L'âge moyen des patients était de 63 ans, avec un sex-ratio F/H de 1,13. L'âge médian d'apparition du diabète chez les patients était de 13 ans, avec une glycémie moyenne de 1,64 et une hémoglobine A1c moyenne de 8,26%. Les comorbidités étaient les suivantes: 30 % de maladies cardiovasculaires, 25 % d'hypertension et 14 % de dyslipidémie; 30 % des patients n'avaient aucune comorbidité. Quarante-six pour cent des patients ont signalé des effets indésirables et 54 % n'ont signalé aucun effet indésirable. Vingt-huit pour cent des effets indésirables étaient d'ordre gastro-intestinal, 18 % des troubles cutanés, 14 % des infections urinaires, 12 % des hypoglycémies, 12 % des troubles du système nerveux, 8 % des infections des voies respiratoires et 8 % des troubles généraux.Conclusion:Cette étude montre que les gliptines restent une option sûre car les effets secondaires semblent assez bien tolérés par les patients. Les effets indésirables peuvent avoir un impact sur la compliance des patients et poser un problème d'adhésion au traitement. Ainsi, il serait avantageux de développer l'éducation thérapeutique des patients diabétiques pour détecter et gérer les effets indésirables.

Veterinary perspectives on the urbanization of leishmaniosis in Morocco.

BACKGROUND: Leishmaniosis caused by Leishmania infantum, L. major and L. tropica is endemic in Morocco. Growing evidence of both human and canine Leishmania infections in urban centres has been reported. Since many forms of the disease are zoonotic, veterinarians play an important role in leishmaniosis control by intervening at the parasite host level. This study aimed to bring together One Health principles to connect canine and feline leishmaniosis epidemiology within urban centres of Morocco (Rabat and Fez) and assess the level of awareness of Moroccan veterinarians about facing this threat. METHODS: A molecular survey was conducted for Leishmania DNA detection in canine (n = 155) and feline (n = 32) whole-blood samples. Three conventional polymerase chain reaction (PCR) protocols were implemented. The first PCR aimed at identifying infected animals by targeting Leishmania spp. kinetoplast minicircle DNA (kDNA). The second and third PCR targeted the Leishmania internal transcribed spacer region (ITS-1) and the Leishmania small subunit ribosomal RNA (SSUrRNA) gene, respectively, aiming at identification of the infecting species after Sanger sequencing-positive amplicons. Total immunoglobulin G (IgG) against Leishmania spp. was evaluated in 125 dogs by enzyme-linked immunosorbent assays (ELISA) using an in-house protocol, including three Leishmania-specific antigens (SPLA, rKDDR and LicTXNPx). Sera from 25 cats were screened for total IgG to Leishmania spp. by an indirect immunofluorescence antibody test (IFAT). An online questionnaire was presented to Moroccan veterinarians addressing their knowledge and practices towards animal leishmaniosis. RESULTS: Overall, 19.4% of the dogs tested positive for Leishmania kDNA and ITS-1 and sequencing revealed infection with L. infantum among PCR-positive dogs. These animals presented a wide range of ELISA seropositivity results (16.7%, 34.9% and 51.6%) according to the tested antigens (rKDDR, SPLA and LicTXNPx, respectively). Use of kDNA-PCR revealed 12.5% cats positive to Leishmania spp. otherwise found to be seronegative by IFAT. CONCLUSIONS: A considerable prevalence of infection was identified in dogs from urban centres of Morocco. Additionally, this is the first report of feline infection with Leishmania spp. in this country and in urban settings. Moroccan veterinarians are aware that animal leishmaniosis is endemic in Morocco, representing a public health threat, and are knowledgeable about canine leishmaniosis diagnosis and treatment.

Prevalence and determinant factors of depression and anxiety in people with chronic kidney disease: a Moroccan cross-sectional study.

Introduction: the chronic kidney disease (CKD), is associated with various psychiatric conditions and poorer quality of life. The main objective of this study is to estimate the prevalence of depression and anxiety among CKD patients and to assess their determinant factors. Methods: this is a cross-sectional study in a Moroccan university hospital. Patients aged ≥18 years and followed for more than one year for a stage 3 to 5 CKD, not under renal replacement therapy (RRT) were included. The data were collected using a questionnaire and the hospital anxiety and depression scale (HADS). The association between depression and anxiety sub-scores and the estimated glomerular filtration rate (eGFR) was assessed using simple and multiple linear regression. Results: eighty-three patients (mean age 61.7 ± 14.1 years, and 61.4% were women), were included. Regarding the stages of CKD, 10.7% were in stage 3, 52.2% in stage 4, and 25% in stage 5 of CKD. The median of the depression sub-score was 5.00 (IQR (2.00; 10.0)). The median of the depression sub-score was 5.00 (IQR (2.00; 10.09)), and the median of the anxiety sub-score was 6.00 (IQR (4.00; 9.00)). It also shows that 22.0% of patients had depression (stage 4 = 23.8%, stage 5 = 36.8%) and 22.2% had anxiety (stage 4 = 26.2%, stage 5 = 33.3%). Both depression and anxiety scores were significantly associated with the eGFR before (p<0.001, p= 0.001 respectively) and after adjustment (p=0.001, p=0.002 respectively). Conclusion: according to this study depression and anxiety are strongly related to eGFR.

Adherence to the Mediterranean Diet and Colorectal Cancer Risk Among Moroccan Population: Hospital-Based Case Control Study.

BACKGROUND: Colorectal cancer (CRC) is a significant public health problem, including Morocco. The Mediterranean Diet (MD) has demonstrated potential anticancerogenic effects toward CRC in Northern Mediterranean countries. Using a Modified Mediterranean Diet (MMD) score adapted to southern countries, we investigated the relationship between adherence to the MD and the risk of CRC among the Moroccan population. MATERIAL AND METHODS: During the study, we recruited 395 cases matched with 395 controls by sex and age (± 3 years). Using an adapted Food Frequency Questionnaire, we assessed the dietary intakes of participants to calculate the MMD score. We estimated the odds ratio and 95% confidence interval for both basic and adjusted models to evaluate the relationship between adherence to the MD and the risk of CRC. RESULT: We observed a significant inverse association between adherence to the MD and CRC risk. In the adjusted model, moderate adherence to the MD was associated with 52% lower risk of CRC [odds ratio (OR*): 0.48 and 95% confidence interval (95% CI): 0.37-0.69], while high adherence to the MD was associated with 61% lower risk of CRC compared to the lowest category. When stratified by sex, both moderate [OR*: 0.36 (CI95%: 0.27-0.55)] and high [OR*: 0.43 (CI95%:0.27-0.74)] adherence were inversely correlated with CRC risk for women, while for men, only high adherence was inversely correlated with the risk of CRC [OR*: 0.3 (CI95%:0.19-0.5)]. CONCLUSION: Adherence to MD is associated with a decreased risk of CRC, an association that may be influenced by tumor location, sex, and age. Despite certain differences between northern and southern countries, the MD can be an effective preventative measure against CRC for populations in the Southern Mediterranean region.

Association between biomass exposure and COPD occurrence in Fez, Morocco: results from the BOLD study.

OBJECTIVE: To investigate the association between biomass exposure and chronic obstructive pulmonary disease (COPD) in a representative sample of adults from the Moroccan population METHODS: A cross-sectional study was conducted in Fez as part of the Burden of Obstructive Lung Disease (BOLD) study, which included apparently healthy subjects aged 40 years and above. Biomass exposure was defined as self-report use of various biomass types for heating or cooking. The Wood Heating Exposure Index, and the Cooking Biomass Exposure Index were used to assess biomass exposure. Participants underwent post-bronchodilator spirometry and COPD was defined as having a forced expiratory volume in 1 s/forced vital capacity ratio <0.7. Descriptive, univariate and multivariable statistical analyses adjusting for potential confounders including age, sex, smoking, education level, Mokken scale (wealth index) and occupational dust exposure were performed for the general population and separately for men and women. RESULTS: A total of 760 subjects were included, comprising 350 men and 410 women. In the multivariable analyses, we found a statistically significant association between a higher Wood Heating Exposure Index and COPD in men (adjusted OR=3.8; 95% CI: 1.4 to 10.4). While for women, a high Cooking Biomass Exposure Index was the main factor potentially linked to the increased risk of COPD (adjusted OR=7.2; 95% CI: 1.7 to 30.0). CONCLUSION: This study suggests that biomass exposure is a significant risk factor for COPD development in both men and women, independently of the smoking status which is known as its main risk factor.

Impact of COVID-19 on child tuberculosis hospitalization.

INTRODUCTION: Morocco has made remarkable progress in the fight against tuberculosis, but the Covid-19 pandemic has affected tuberculosis control worldwide, with notable fluctuations in tuberculosis epidemiology during and after the pandemic. AIM: To describe the impact of the Covid-19 pandemic on the rate of hospitalization for tuberculosis and its different localizations in children. METHODS: We conducted a retrospective study based on the analysis of medical records of TB patients hospitalized within the Children's Hospital in Casablanca, during the periods before (2018-2019), during (2020) and after (2021-2022) Covid-19 quarantine. RESULTS: Throughout the study period (2018-2022), the total number of patients hospitalized in our department was 7390, including 283 children were hospitalized for tuberculosis, with a mean age of 6 years. Before the Covid-19 pandemic, the average number of tuberculosis cases was 49 per year, of which the percentage of pulmonary tuberculosis was 32% and extra-pulmonary tuberculosis 68%. The number of cases was 23 per year during the quarantine period, with a percentage of pulmonary tuberculosis of 26% and extra-pulmonary tuberculosis of 74%. After the quarantine period, this number rose to 81 cases per year, of which 21% were pulmonary tuberculosis and 79% extrapulmonary tuberculosis (pleural tuberculosis was predominant in 44.1% of cases). CONCLUSION: These results are consistent with data published by the World Health Organization, and with the findings of another study we carried out on the impact of COVID-19 on hospital admissions for acute lower respiratory tract infections. It is very likely that the reduction in the number of tuberculosis cases during the quarantine period is due to social distancing, which leads to a reduction in the transmission of tuberculosis between people as well as to the disruption of the national tuberculosis control program in Morocco, when positive cases are identified.

Prevalence of postmenopausal osteoporosis in Morocco: a systematic review and meta-analysis.

INTRODUCTION: This systematic review and meta-analysis was conducted as part of the update of Moroccan recommendations for the management of postmenopausal osteoporosis. Its aim was to estimate the prevalence of postmenopausal osteoporosis in Morocco, based on available bibliographic data. METHODS: We conducted a systematic search of the Medline/PubMed, Scopus, and Embase databases to identify articles published between January 2000 and January 2024. We included all observational studies reporting the prevalence of osteoporosis in postmenopausal women in Morocco. Two reviewers independently contributed to the study selection and data extraction. We assessed the risk of bias in the included studies using the Joanna Briggs Institute tool. Statistical analyses were performed using Stata with the Freeman-Tukey double arcsine transformation. Heterogeneity was assessed using the I2 test statistic. Meta-regression analysis was used to investigate the effect of the date on the prevalence. Publication bias was assessed by DOI plots and the LFK index. RESULTS: An electronic search found a total of 161 citations from the databases. After excluding the irrelevant articles, 17 eligible studies were included. This meta-analysis included 5097 postmenopausal women. The pooled prevalence of postmenopausal osteoporosis was 32% (95% CI 28-36). Heterogeneity was statistically significant (I2 = 89.67%). There was no significant difference between subgroup analyses performed by risk of bias and sample size. The prevalence rate was significantly higher in 2006-2012 (36%; 95% CI 31-42; I2 = 88.7%; p < 0.001) than in 2013-2019 (27%; 95% CI 22-32; I2 = 85.9%; p < 0.001). Meta-regression showed that the prevalence of osteoporosis decreases very slightly (0.016% per year). This decrease becomes nonsignificant if only studies with a low risk of bias are included in the meta-regression (coefficient - 7.77, p = 0.667, I2 0%). No publication bias was detected in this meta-analysis. CONCLUSION: Our results indicate that postmenopausal osteoporosis is prevalent in Morocco, which is a developing country; however, the prevalence of this disease is aligned with that of industrialized countries.

Psychoactive substance use and associated factors among Mohammed first university students, Oujda, Morocco: a cross-sectional study.

BACKGROUND: The use of psychoactive substances, including tobacco, alcohol, and others, remains a major public health problem. However, few studies have been conducted on Moroccan university students. This study aimed to assess the prevalence and associated factors of substance use among students at Mohammed First University, Oujda, Morocco. METHODS: We conducted this cross-sectional study with students enrolled at one of the Mohammed First University of Oujda's institutes as part of the 2021-202 academic year. We used a self-administered survey to collect data anonymously. We cleaned the data and then entered it into IBM SPSS Statistics 21 for analysis. Data analysis involved descriptive statistics as well as univariate and multivariate analysis. We considered a P value < 0.05 as the level of significance. RESULTS: In this study, out of 500 students we asked to complete the survey, 478 responded; the response rate was 95.6%. The average age was 21.1 ± 3.0, and the M/F sex ratio was 0.97. The lifetime prevalence of psychoactive substance use among Oujda University students was 28.7%. The most commonly used substances were tobacco (24.1%), alcohol (15.9%), cannabis (13.4%), sedatives (6.9%), stimulants (5.2%), and cocaine (4.4%). Male sex, age > 20 years, self-financing, school failure (one year repeated or more), the practice of a leisure activity, the presence of a personal medical or psychiatric history, and the presence of a family medical history were all significantly associated with the use of psychoactive substances. CONCLUSION: Our study revealed a significant prevalence of psychoactive substance use among university students in Oujda, highlighting the need for interventions at various levels. Further analytical studies are necessary to better understand the initiation and maintenance of psychoactive substance use and to identify all associated factors to enhance prevention strategies against substance use disorders.

Evaluating the Effectiveness of the COPD Assessment Test (CAT) in Screening for Chronic Obstructive Pulmonary Disease.

Background: Chronic obstructive pulmonary disease (COPD) is a major public health problem that remains largely under-diagnosed, mainly due to the under-use of spirometry to establish the diagnosis. The aim of this study is to evaluate the effectiveness of the Moroccan Arabic dialect version of the COPD Assessment Test (CAT) in screening for COPD. Methods: This was a cross-sectional study carried out in primary care facilities in Morocco, involving participants aged 40 and over. The performance of CAT in detecting cases of COPD was measured with reference to the results of spirometry, considered to be the gold Standard. Results: A total of 477 participants were included in the study. The prevalence of COPD was 6.7%. Internal consistency of the Moroccan Arabic dialect version of the CAT was high, with a Cronbach's alpha of 0.89. The total score of the CAT and of each item was significantly higher in subjects with COPD than in those without (P=0.000). Significantly negative correlations were found between CAT total score and FEV1 (r = -0.33, p=0.000), CAT and FVC (r = -0.22, p=0.000), CAT and FEV1/FVC ratio (r = -0.22, p=0.000). The receiver operating characteristic curve showed an area under the curve of 0.93. A CAT score of 10 was the optimal cut-off value for COPD screening, with a sensitivity, specificity, positive predictive value, and negative predictive value of 78.1%, 93.9%, 48.1% and 98.4%, respectively. Conclusion: The results of the present study showed that the CAT could be used as a screening tool for COPD. The use of this tool by healthcare professionals in primary care settings will improve and promote early diagnosis of this chronic disease.

[Phytoplankton population dynamics along the Casablanca - El Jadida Atlantic coast]. / Dynamique du peuplement phytoplanctonique le long de l'axe côtier Casablanca ­ El Jadida.

Our taxonomic study from March 2014 to November 2015 along the atlantic coast between Casablanca and El Jadida revealed that phytoplanktonic structure is mainly represented by Diatoms (Bacillariophyceae), Dinoflagellates (Dinophyceae), Silicoflagellates (Dictyophyceae) and Euglenophyceae with a clear dominance of Diatoms and Dinoflagellates. A total of 101 taxa of planktonic algae have been identified revealing a relatively diversified taxocenosis. In terms of respective diversity, the Diatoms are represented by 62 taxa (61.4%), the Dinoflagellates by 36 taxa (35.6%) whereas the other two groups of Silicoflagellates and Euglenophyceae are only represented by 3 species (3.0%). Regarding potentially toxic species, more than fifteen taxa have been identified, most of which were Dinoflagellates and Diatoms (Pseudo-nitzschia australis and Pseudo-nitzschia cuspidata). The total phytoplankton densities exhibited great spatial and temporal variations as shown by analyses of diversity (H') and equitability (E) indices at the different coast sites investigated throughout the 2014-2015 years. Massive proliferation of some toxic species (e.g. Pseudo-nitzschia australis and Pseudo-nitzschia cuspidata, Lingulodinium polyedrum, Karenia mikimotoi) was also noticed. In addition, our study revealed the presence of opportunistic species (e.g. Eutreptiella, Thalassiosira, Prorocentrum scutellum) and of the new ectoparasite Dinoflagellate Amyloodinium ocellatum for the first time in Morocco. The detection of such diversity of toxic species, sometimes with alarming concentrations, should prompt the competent authorities to broaden the spectrum and frequency of biomonitoring to uncontrolled seafood harvesting sites.

Title: Dynamique du peuplement phytoplanctonique le long de l'axe côtier Casablanca ­ El Jadida. Abstract: Notre étude taxonomique entre mars 2014 et novembre 2015 le long de la côte atlantique entre Casablanca et El Jadida a permis de déceler une flore phytoplanctonique représentée par les Diatomées, Dinoflagellés, Silicoflagellés et Euglenophycées avec une nette dominance des Diatomées et des Dinoflagellés. Au total, 101 taxons d'algues planctoniques ont été identifiés, témoignant d'une taxocénose relativement diversifiée. Dans cet ensemble, les Diatomées sont représentées par 62 taxons (61,4 %), les Dinoflagellés par 36 taxa (35,6 %) et les deux autres groupes (Silicoflagellés et Euglénophycées) ne sont représentés que par 3 espèces seulement (3,0 %). En ce qui concerne les espèces potentiellement toxiques, plus d'une quinzaine de taxons ont été identifiés dont la plupart sont des Dinoflagellés et des Diatomées (Pseudo-nitzschia australis et Pseudo-nitzschia cuspidata). L'analyse de l'évolution spatiotemporelle des indices de diversité (H') et d'équitabilité (E) révèle des fluctuations saisonnières prononcées sans montrer, pour autant, une grande analogie entre les différents sites prospectés. Par ailleurs, les densités phytoplanctoniques totales présentent de grandes variations à la fois spatiales et temporelles (sur les deux cycles annuels). La présence de proliférations massives de certaines espèces potentiellement toxiques (Pseudo-nitzschia australis et Pseudo-nitzschia cuspidata, Lingulodinium polyedrum, Karenia mikimotoi), d'une nouvelle espèce de Dinoflagellé ectoparasite pour le Maroc (Amyloodinium ocellatum) et d'autres espèces opportunistes (Eutreptiella, Thalassiosira, Prorocentrum scutellum) a été notée au cours de cette étude. La détection des espèces potentiellement toxiques, parfois à des concentrations alarmantes, devrait inciter les autorités compétentes à élargir le spectre et la fréquence de biosurveillance aux sites non contrôlés.

Epidemiology, outcomes and prognosis of infective endocarditis in Northern Morocco.

INTRODUCTION: Infective endocarditis is a rare but potentially severe disease, associated with significant morbidity and mortality. Our study aims to describe the epidemiology and management aspects of endocarditis in northern Morocco and compare it with international management guidelines. MATERIALS AND METHODS: This is a retrospective study involving all patients hospitalized in the cardiology department of the University Hospital of Tangier for infective endocarditis over a period of 4 years and 7 months, from May 2019 to February 2024. RESULTS: Eighty patients were hospitalized for IE during the study period. The average age of the patients was 46 years, with an even sex ratio. IE concerned native valves in 77% of cases, mechanical prostheses in 19% of cases, and on bio prostheses in 4%. The average diagnostic delay was 25 days. Blood cultures were negative in 59% of cases. The predominant infective microorganism was the bacteria Staphylococcus (65.6%). Imaging results showed vegetations in 76.3% of cases, predominantly on the mitral valve (39.3%), followed by the aortic valve (21.3%). The main complications included heart failure (51.2%), peripheral arterial embolisms (22.5%) and splenic infarction (17.5%). Management wise, the most commonly used antibiotic therapy was a combination of ceftriaxone and gentamicin. Clinical and biological improvement was observed in 70% of cases, with a mortality rate of 12.5%. Twelve patients underwent surgery (15%). Urgent surgery was indicated in 66,7% of the operated patients. CONCLUSION: Our study highlights the challenges in managing infective endocarditis in northern Morocco. The prognosis of infective endocarditis can be improved through multidisciplinary management within the implementation of an Endocarditis Team.
