Impact of CBE-based screening program on care pathway, stage at diagnosis, nature of treatment, and overall survival among breast cancer patients in Morocco.

BACKGROUND: This study aimed to indirectly examine whether the implementation of clinical breast examination-based screening program in Morocco has been successful in downstaging and improving survival rates. Breast cancer patients detected through the screening pathway were compared with those detected through self-referral over the same period in terms of cancer stage at diagnosis, tumor characteristics, care delays, and survival. METHODS: A prospective observational study was conducted between April 2019 and August 2020 at two major public oncology centers. RESULTS: A total of 896 women with confirmed breast cancer were recruited (483 were program-referred and 413 were self-referred). The authors did not report any significant difference between the two groups in terms of stage at diagnosis, molecular profile, or histopathological grade. Early-stage cancer (stage I-II) was detected in 55.7% of self-referred participants compared to 55.5% of program-referred participants. Median intervals between symptom recognition, pathological diagnosis, and treatment initiation were not significantly different between the two groups. Similarly, survival after treatment showed no significant difference between patients screened by the program and self-referred patients. The 3-year survival rate after treatment was 94.5% for patients referred through the program and 88.6% for patients not referred through the program (p = .16). CONCLUSIONS: This study highlights the importance of equitable and timely access to high-quality diagnosis and treatment facilities, leading to substantial downstaging and enhanced survival rates. Continued efforts to improve quality and expand coverage to include asymptomatic women will consolidate the health infrastructure gains achieved by the Moroccan breast cancer screening program.

Cluster analysis of cancer knowledge, attitudes and behaviors in the Moroccan population.

BACKGROUND: Cancer has become a major health concern due to the increasing morbidity and mortality rates, and its negative social, economic consequences and the heavy financial burden incurred by cancer patients. About 40% of cancers are preventable. The aim of this study was to assess the knowledge, attitudes, and practices regarding cancer prevention, and associated characteristics to inform the development of targeted cancer prevention campaigns and policies. METHODS: We conducted a cross-sectional survey of adult patients at Mohamed Sekkat and Sidi Othmane Hospitals in Casablanca, Morocco. Data collection was conducted by two trained interviewers who administered the questionnaire in-person in the local language. An unsupervised clustering approach included 17 candidate variables for the cluster analysis. The variables covered a wide range of characteristics, including demographics, health perceptions and attitudes. Survey answers were calculated to compose qualitative ordinal categories, including a cancer attitude score and knowledge score. RESULTS: The cluster-based analysis showed that participants in cluster 1 had the highest mean attitude score (13.9 ± 2.15) and percentage of individuals with a high level of knowledge (50.8%) whereas the lowest mean attitude score (9.48 ± 2.02) and knowledge level (7.5%.) were found in cluster 3. The participants with the lowest cancer attitude scores and knowledge levels were aged 34 to 47 years old (middle age group), predominantly females, living in rural settings, and were least likely to report health professionals as a source of health information. CONCLUSIONS: The findings showed that female individuals living in rural settings, belonging to an older age group, who were least likely to use health professionals as an information source had the lowest levels of knowledge and attitudes. These groups are amenable to targeted and tailored interventions aiming to modify their understanding of cancer in order to enhance the outcomes of Morocco's on-going efforts in cancer prevention and control strategies.

Breast cancer treatment and its impact on survival in Morocco: a study over a decade.

BACKGROUND: In Morocco, much progress has been made in breast cancer treatment. However, there is limited information on survival outcomes of breast cancer patients according to their therapeutic management. METHODS: A pattern-of-care study was conducted in Morocco's two main oncology centres: Rabat and Casablanca and has shown that major progress has been made in the quality of care with survival rates comparable to those in developed countries. The present study focuses on the different therapeutic strategies used in breast cancer and their impact on prognosis. Patients were classified into two categories: those considered as appropriately managed and those who were not. RESULTS: A total of 1901 women with stage I to III breast cancer were included in this study, the majority (53%) were adequately managed and had better disease-free survival (DFS) rates than those who were not: DFS at 3 years (88% versus 62%) and at 5 years (80% versus 50%). Potential significant determinants of better management were: treatment in Rabat's oncology centre, treatment between 2008 and 2012, being aged younger than 60 years, and early TN stage. CONCLUSION: This study demonstrated the value of proper integrated and coordinated management in a comprehensive cancer centre, to improve breast cancer survival.

Chemotherapy-related adverse effects with anthracycline and taxane-containing regimens in patients with localized Breast cancer: a descriptive study : Mohammed VI University Hospital, Medical Oncology Department, Marrakech, Morocco.

BACKGROUND: Although the side effects of chemotherapy are frequently described in research studies, there is little evidence on how common they are in everyday clinical care. This study's goal was to assess the most prevalent short-term side effects experienced by patients with localized breast cancer, undergoing chemotherapy based on anthracyclines and taxane-containing treatments, at the medical oncology department of the Mohammed VI University Hospital of Marrakech, Morocco. METHODS: This was a descriptive study. We conducted a listening session at the outpatient department of the hospital with the help of a structured questionnaire. The session engaged 122 women who had undergone cycles of chemotherapy. A chi-square test was used to compare the incidence and relative risk of short side effects with both anthracycline and taxane-containing regimens. RESULTS: The average age of participants was 49.1 years. In both regimens, the findings highlighted the frequency and relative risk of the following adverse effects: systemic symptoms (fever, asthenia and sleep disorder), gastrointestinal toxicity (Vomiting, nausea, diarrhoea, constipation, mucositis and loss of appetite), dermatological toxicity (Skin reactions on hands/feet, nail toxicity, allergies, alopecia and peripheral edema), neurological toxicity (neuropathy), arthromyalgia and ocular toxicity. CONCLUSIONS: In conclusion, it is crucial for healthcare professionals to be conscious of the significance of these adverse effects. They must also know how to manage them. Likewise, the listening approach highlights its importance in the daily follow-up and monitoring of patients.

Cytogenetic and epidemiological profile of chronic myeloid leukemia in Morocco.

Chronic myeloid leukemia (CML) is a neoplastic disease of genetic origin resulting from clonal proliferation of hematopoietic stem cells (HSCs). The reciprocal translocation t(9;22)(q34;q11) is the main chromosomal abnormality involved in this pathology, usually detected by conventional cytogenetics. This article aims to investigate the epidemiological, cytogenetic, therapeutic, and clinical characteristics of Moroccan patients with CML. This research represents the first large-scale study of CML patients in Morocco and was carried out at Institut Pasteur of Morocco. Bone marrow samples were processed for cytogenetic analysis, and karyotypes were described according to an international system of human cytogenetic nomenclature (ISCN 2016). Patients were studied according to their epidemiological characteristics, clinical information and cytogenetic results. For statistical calculations, R version 4.3.1 was used to analyze the data and calculate the statistical parameters. RStudio and Power BI were used for data visualization. The National Cancer Institute (NCI) Surveillance, Epidemiology, and End Results (SEER) method of incidence estimation was used to calculate our incidence. We received 826 patients (from 1992 to 2023) who were referred for suspected CML or who were undergoing treatment. Only 650 patients with confirmed CML were included in the study, all of whom underwent their first cytogenetic test. The median age of our patients was 45 years and the sex ratio was 1.03. At the time of diagnosis, 147 (30%) of the patients had clinical manifestations. Most patients were diagnosed in the chronic phase (94.5%). Nineteen complex variant translocations of the Philadelphia (Ph) chromosome were detected. At the time of diagnosis, 55 (11.5%) patients had ACAs, of which 30 (54.5%) were high-risk ACAs. Based on data from 174 patients treated with imatinib, the median time to complete cytogenetic response (CCyR) was 11 months, and at the last cytogenetic follow-up, 81 patients (46.6%) achieved CCyR, while 64 patients (36.8%) showed no response to treatment. Regarding adherence to European LeukemiaNet (ELN) guidelines, 58 patients (33%) were followed according to these guidelines, with optimal treatment in 8.6%, suboptimal treatment in 7% and treatment failure in 18%. The estimated incidence of chronic myeloid leukemia calculated is 0.6 cases per 100,000 in the Casablanca region. This study provides a detailed overview of CML in Morocco, highlighting important clinical, cytogenetic and therapeutic aspects despite some limitations. It also highlights the need to deepen our understanding of this complex disease for disease management in our specific context.

Epidemiology and risk factors for staphylococcal urinary tract infections in the Moroccan Casablanca area.

PURPOSE: This study aimed to ascertain the prevalence and risk factors for developing staphylococcal urinary tract infections (UTIs) in the Casablanca area of Morocco. METHODS: In Casablanca, Morocco, a retrospective evaluation of 772 UTIs patients was conducted between January 2020 and December 2022. The research included two groups of patients: those with staphylococcal UTIs and those without. Sex, age, chronic illnesses, antibiotic exposure, urinary catheterization, urological surgery, and UTIs history were the risk variables assessed. We employed a logistic regression model to identify the characteristics that were predictive of staphylococcal UTIs. RESULTS: Eight staphylococcal species were responsible for 16.84% of UTIs in 772 non-repeating individuals. Patients infected with S. saprophyticus (35.38%) were the most common, followed by those infected with S. epidermidis (24.61%), S. aureus (13.85%), and S. hemolyticus (10.78%). Multivariate logistic regression analysis revealed that male sex (95% CI: 0.261-0.563), immunosuppression and immunosuppressive treatments (95% CI: 0.0068-0.64), chronic diseases (95% CI: 0.407-0.965), previous UTIs (95% CI: 0.031-0.228), frequency of urination more than 8 times a day (95% CI:1.04-3.29), frequency of urination once or twice a day (95% CI: 1.05-2.39), and urinary catheterization (95% CI: 0.02-0.22) were the most likely predictors of staphylococcal UTIs. In addition, a larger proportion of patients with staphylococcal UTIs were made aware of the risk factors associated with staphylococcal UTIs (52.31%, χ2 = 4.82, = 0.014). CONCLUSIONS: This is the first global study to evaluate the predictive factors for acquiring UTIs caused by staphylococci. Monitoring these factors will enable medical authorities to devise effective strategies for managing UTIs and combating antibiotic resistance.

Post-Cambrian survival of the tubicolous scalidophoran Selkirkia.

Scalidophoran worms represent common infaunal components of early and middle Cambrian Burgess Shale-type fossil biotas. Early scalidophorans resemble extant priapulids based on overall morphology, but the genus Selkirkia represents the earliest record of tube dwelling for the group. Despite its ubiquitous presence in exceptional marine deposits, whether the exclusively Cambrian occurrence of Selkirkia reflects its entire evolutionary history or is affected by taphonomic biases remains unresolved. Here, we demonstrate the post-Cambrian survival of Selkirkia based on new material from the Lower Ordovician Fezouata Shale biota of Morocco. The discovery of Selkirkia in the Fezouata Shale extends the biostratigraphic range of the genus by 25 million years and its palaeobiogeographic occurrence to the high latitudes of Gondwana, strengthens the evolutionary links between Cambrian and Ordovician Burgess Shale-type biotas and increases scalidophoran diversity for the Fezouata Shale biota otherwise consisting exclusively of the palaeoscolecid Palaeoscolex? tenensis. The tube of Selkirkia underwent negligible external change for over 40 million years, indicating a high degree of morphological stasis during the Early Palaeozoic. A tubicolous mode of life is rare among extant priapulids and expressed only in Maccabeus, which forms a delicate tube from agglutinated plant debris, unlike the macroscopic secreted cuticular tube of Selkirkia.

PrEPare_Morocco a successful community-based PrEP delivery demonstration program for men who have sex with men and female sex workers in Morocco.

Pre-exposure prophylaxis (PrEP) is an effective HIV prevention tool, recommended for persons at substantial risk for HIV, such as female sex workers (FSW) and men who have sex with men (MSM). We present Morocco's and the Middle East/North Africa's first PrEP demonstration project. Our pilot aimed to assess the feasibility and acceptability of a community-based PrEP program for FSW and MSM in Morocco's highest HIV prevalence cities: Agadir, Marrakech, and Casablanca. From May to December 2017, 373 eligible participants engaged in a 5-9 month program with daily oral TDF/FTC and clinic visits. Of these, 320 initiated PrEP, with 119 retained until the study's end. We report an 86% PrEP uptake, 37% overall retention, and 78% retention after 3 months. No seroconversions occurred during follow-up. These results underscore PrEP's need and acceptability among MSM and FSW and demonstrate the effectiveness of a community-based PrEP program in Morocco. These findings informed Morocco's current PrEP program and hold potential for the wider region with similar challenges.

Investing in midwifery for sustainable development goals in low- and middle-income countries: a cost-benefit analysis.

BACKGROUND: Maternal and neonatal mortality in low- and middle-income countries is frequently caused by inadequate management of obstetric and neonatal complications and a shortage of skilled health workers. The availability of these workers is essential for effective and high-quality healthcare. To meet the needs of sexual, reproductive, maternal, new-born, child, and adolescent health by 2030, more than one million health workers, including 900 000 midwives, are required globally. Despite this, uncertainty persists regarding the return on investment in the health workforce. METHODS: The objective of this research was to determine the cost-benefit ratio of increasing investment in midwifery in Morocco from 2021 to 2030. A comparative analysis was conducted between scenarios "with" and "without" the additional investment. The costs and benefits were estimated using relevant data from national and international sources. RESULTS: Following the International Confederation of Midwives' recommendations, it is advised that Morocco recruit 760 midwives annually to achieve 95% of universal health coverage. This increase in midwifery could result in saving 120 593 lives by 2030, including reducing maternal deaths by 3 201, stillbirths by 48 399, and neonatal deaths by 68 993. The estimated economic benefit of investing in midwives was US$ 10 152 287 749, while the total cost was US$ 638 288 820. Consequently, the cost-benefit ratio was calculated as 15.91, indicating that investing in midwifery would provide 16 times more benefits than costs. CONCLUSION: Increasing investment in midwifery appears to be an efficient strategy for achieving comprehensive maternal and child health coverage in low- and middle-income countries.

Knowledge, attitudes and practices towards epilepsy in morocco: A cross-sectional study.

BACKGROUND: This study aims to assess knowledge, practices and attitudes of the general Moroccan population towards epilepsy and to highlight predictive factors. METHOD: A cross-sectional study was conducted in the Casablanca-Settat Moroccan region. A questionnaire was used to collect sociodemographic data and item answers from 400 people with epilepsy (PWE) and without epilepsy caregivers on dependent variables: knowledge, attitudes, and practices towards epilepsy. Bivariate and logistic regression analyses were performed using IBM SPSS Statistics 21.0. Statistical significance was set when P value < 0.05. RESULTS: The rates of poor knowledge, practices, and attitudes toward epilepsy were 11.5 %, 41 %, and 66.6 %, respectively. In the multivariate analysis, the risk of having poor knowledge about epilepsy was favored by lack of education (ORa = 4.31;CI95%:1.83-10.13;p = 0.001) and the absence of familiarity with epilepsy (ORa = 4.05;CI95%:1.92-8.54;p < 0.001). The risk of preferring allopathic practices to treat epilepsy was associated with lack of education (ORa = 2.21;CI95%:1.01-4.82;p = 0.046), residence in a city outside Casablanca (ORa = 2.33;CI95%:1.06-5.15;p = 0.035), age over 59 years (ORa = 2.50;CI95%:1.26-4.95; p = 0.008), residence in a rural areas (ORa = 4.41;CI95%:2.61-7.47;p < 0.001) and absence of familiarity with epilepsy (ORa = 4.08;CI95%:2.33-7.15;p < 0.001). Predictors of stigma towards epilepsy were female sex (ORa = 3.05;CI95%:2.04-4.56;p < 0.001) and the tendency to abandon anti-seizure medication for allopathic alternatives (ORa = 3.98;CI95%:2.21-7.17;p < 0.001), whereas advanced age was a protective factor (ORa = 0.57;CI95%:0.36-0.89;p = 0.014[39-59 years vs 18-29 years];ORa = 0.44;CI95%:0.23-0.82;p = 0.011[>59 years vs 18-29 years]). CONCLUSIONS: The rate of poor attitudes and treatment-seeking behavior was high. This socio-cultural context certainly impacts the quality of life and care of Moroccan PWE. These results should be considered to raise awareness in the Moroccan population.

The analysis of asthma control using Markov models: MOSAR study (Multicenter Observational Study of Asthma in Rabat-Morocco).

BACKGROUND: This study aimed to analyze the probabilities of transitioning between controlled, uncontrolled, and partially controlled states of asthma patients and investigate the influence of age, smoking, dust allergy, and obesity on these probabilities. METHODS: This study aimed to analyze the probabilities of transitioning between controlled, uncontrolled, and partially controlled states of asthma patients and investigate the influence of age, smoking, dust allergy, and obesity on these probabilities. RESULTS: Results showed that controlled patients were more likely to remain in that state, with approximately 79 out of 100 patients expected to stay in optimal control in the long term. A discrete nonhomogeneous time Markov Model with the stationarity criterion was used to examine the factors affecting patient states and transitions. Patients seen during the spring and summer seasons were more likely to move into a controlled state compared with those seen in the fall and winter seasons. Patients with dust allergies and obesity significantly impacted asthma exacerbation, with overweight patients more likely to transition into a controlled state. The study estimated the transition intensities matrix under certain conditions, assuming the regularity of patients. In the long term, the probability of an asthmatic patient being in a controlled state was approximately 0.8. CONCLUSION: This study provided insights into the probabilities and factors influencing asthma progression in Morocco. Dust allergy and obesity were identified as significant contributors to asthma exacerbation, emphasizing the need for effective management strategies.

Unraveling the Diversity of GJB2 Mutations in Nonsyndromic Hearing Loss: A Comprehensive Study in the Moroccan Population.

INTRODUCTION: Despite the high genetic heterogeneity of hearing loss, mutations in the GJB2 gene are a major cause of autosomal recessive nonsyndromic hearing loss (NSHL) worldwide. However, the mutation profile of GJB2 in NSHL is under-investigated in Morocco, especially among simplex cases. This study aimed to identify the spectrum and frequency of GJB2 mutations in the Moroccan population among simplex and multiplex families with NSHL. METHODS: Moroccan families with NSHL were selected according to well-defined criteria. Selected families were screened for GJB2 gene variants using direct sequencing of the entire coding region of GJB2. RESULTS: A total of 145 affected individuals from 115 families with NSHL were included in this study (49 simplex, 66 multiplex). Mutations in the GJB2 gene were noted in 28.69% of the families (33/115), of which 75.75% were multiplex families and 24.24% were simplex. In total, seven different mutations were detected: c.35delG(p.G12fs), c.551G>A(p.R184Q), c.139G>T(p.E47X), c.109G>A(p.V37I), c.167delT(p.L56fs), c.617A>G(p.N206S), c.94C>T(p.R32C). The last three mutations have not previously been reported in Morocco. The most common GJB2 mutation was c.35delG (21.73%), followed by p.V37I (2.60%) and p.E47X (1.73%). CONCLUSIONS: Our study confirms a high prevalence of GJB2 variants in the Moroccan population, particularly the c.35delG mutation. Additionally, we have identified previously unreported or rarely reported mutations, revealing a greater diversity of GJB2 mutations. These findings emphasize the importance of comprehensive screening beyond the 35delG mutation for patients with NSHL, regardless of their family history. Integrating this approach into clinical care will enhance diagnosis and management of hearing loss in the Moroccan population.

Histopathological and morphological characterization of Cysticercus fasciolaris isolated from domestic and wild rodents in Morocco.

Cysticercus fasciolaris is a parasitic helminth that usually infects feline and canine mammal hosts. The intermediate hosts (rodents, occasionally lagomorphs, and humans) get infected by the consumption of feed or water contaminated with eggs. Rodents are vectors of disease and reservoirs of various zoonotic parasites. The current survey was aimed at determining endoparasitic helminth infections in rodents in central Morocco. Sampled rodents after specific identification were sacrificed and examined to identify parasitic helminths following ethical guidelines. Parasites were identified using morphological characteristics. A total of 197 specimens of rodents were collected and examined in this study. Ten rodent species were identified morphologically as Rattus rattus, R. norvegicus, Apodemus sylvaticus, Mus musculus, M. spretus, Mastomys erythroleucus, Meriones shawi, M. libycus, Gerbillus campestris, and Lemniscomys barbarus. The parasitological results showed that metacestode of tapeworms was found encysted in the liver, the larval stage of Taenia taeniaeformis develops large multinodular fibrosarcomas which envelope the tapeworm cysts in the liver of the R. rattus and R. norvegicus. Based on morphological data, the metacestode was identified as C. fasciolaris in 23 (23/80) R. rattus 2 (2/8) and R. norvegicus with a prevalence of 11.7 % and 1.0 %, respectively. Rodents are major vectors of human and domestic animal diseases worldwide, and therefore, important parasitic zoonotic agents (C. fasciolaris), which are transmitted by black rats (R. rattus) and brown rats (R. norvegicus), must be considered to prevent the infectivity of humans, domestic animals, and livestock such as cattle, sheep, and rabbits.

Phenolic Compound, Antioxidant, Antibacterial, and In Silico Studies of Extracts from the Aerial Parts of Lactuca saligna L.

Medicinal plants are considered a major source for discovering novel effective drugs. To our knowledge, no studies have reported the chemical composition and biological activities of Moroccan Lactuca saligna extracts. In this context, this study aims to characterize the polyphenolic compounds distributed in hydro-methanolic extracts of L. saligna and evaluate their antioxidant and antibacterial activities; in addition, in silico analysis based on molecular docking and ADMET was performed to predict the antibacterial activity of the identified phenolic compounds. Our results showed the identification of 29 among 30 detected phenolic compounds with an abundance of dicaffeoyltartaric acid, luteolin 7-glucoronide, 3,5-di-O-caffeoylquinic acid, and 5-caffeoylquinic acid with 472.77, 224.30, 196.79, and 171.74 mg/kg of dried extract, respectively. Additionally, antioxidant activity assessed by DPPH scavenging activity, ferric reducing antioxidant power (FRAP) assay, and ferrous ion-chelating (FIC) assay showed interesting antioxidant activity. Moreover, the results showed remarkable antibacterial activity against Escherichia coli, Salmonella typhimurium, Pseudomonas aeruginosa, Enterococcus faecalis, Staphylococcus aureus, and Listeria monocytogenes with minimum inhibitory concentrations between 1.30 ± 0.31 and 10.41 ± 0.23 mg/mL. Furthermore, in silico analysis identified three compounds, including Apigenin 7-O-glucuronide, Quercetin-3-O-glucuronide, and 3-p-Coumaroylquinic acid as potent candidates for developing new antibacterial agents with acceptable pharmacokinetic properties. Hence, L. saligna can be considered a source of phytochemical compounds with remarkable activities, while further in vitro and in vivo studies are required to explore the main biological activities of this plant.

Assessment of patient safety culture in Moroccan primary health care: a multicentric study.

BACKGROUND: Promoting patient safety is a critical concern for developing-countries health systems like Morocco. There is an increasing acknowledgment of the need to create a patient-centered culture with the aim to decrease the number of adverse events related to care and improve health-care quality in Morocco. OBJECTIVE: The purpose of this study is to examine the perceptions of health professionals working in primary care level of care facilities in Morocco about the concept of patient safety culture. METHODS: We conducted a multicentric cross-sectional study of a quantitative nature in primary healthcare facilities in ten Moroccan cities, measuring ten patient safety culture dimensions, from February 2022 to June 2022. Data was collected using the French version of the HSOPSC questionnaire. RESULTS: The most developed dimension of the culture of patient safety was found to be Teamwork within Units (69%), followed by Supervisor/Manager's Expectations & Actions Promoting Patient Safety (59%). The least developed dimensions were Staffing (34%) and Nonpunitive Response to Errors (37%). CONCLUSION: Improving patient safety culture should be a priority for primary healthcare facility administrators and all stakeholders, addressing, in particular, the shortage of human resources. In addition, health personnel should be encouraged to report errors without fear of punitive consequences.

Pesticide contamination pattern from Morocco, insights into the surveillance situation and health risk assessment: a review.

The widespread application of pesticides in Morocco's agriculture renders their monitoring in food and environmental samples very necessary. Recent years have witnessed a growing interest in reporting studies related to the monitoring of pesticide residues in food, water, groundwater, and soil as well as their quantitative health risk assessment. Most published studies have been done by university researchers. However, the lack of research reproducibility remains a problem that considerably limits the possibility of exploiting data from the literature. Our study involves an extensive literature review utilizing search engines with keywords like "pesticide residues," "monitoring," "vegetables and fruits," "water and soil," "risk assessment," and "Morocco" from 2009 to 2023. Analysis of pesticide residues in foodstuffs and environmental samples highlights concerns over compliance with EU regulations, the health risks associated with pesticide exposure, and the necessity for comprehensive monitoring and risk assessment strategies. This paper could help influence policies to develop a strategy and action plan for the sound management of pesticides, including measures to reduce their use, raise awareness, and monitor compliance. Also, this paper could be useful for scientists interested in understanding the current situation and challenges regarding pesticide residues in Morocco, as well as countries with which commercial links exist.

Integrating fuzzy-AHP and GIS for solid waste disposal site selection in Kenitra province, NW Morocco.

Selecting an optimal solid waste disposal site is one of the decisive waste management issues because unsuitable sites cause serious environmental and public health problems. In Kenitra province, northwest Morocco, sustainable disposal sites have become a major challenge due to rapid urbanization and population growth. In addition, the existing disposal sites are traditional and inappropriate. The objective of this study is to suggest potential suitable disposal sites using fuzzy logic and analytical hierarchy process (fuzzy-AHP) method integrated with geographic information system (GIS) techniques. For this purpose, thirteen factors affecting the selection process were involved. The results showed that 5% of the studied area is considered extremely suitable and scattered in the central-eastern parts, while 9% is considered almost unsuitable and distributed in the northern and southern parts. Thereafter, these results were validated using the area under the curve (AUC) of the receiver operating characteristics (ROC). The AUC found was 57.1%, which is a moderate prediction's accuracy because the existing sites used in the validation's process were randomly selected. These results can assist relevant authorities and stakeholders for setting new solid waste disposal sites in Kenitra province.

An evaluative technique for drought impact on variation in agricultural LULC using remote sensing and machine learning.

Drought events threaten freshwater reservoirs and agricultural productivity, particularly in semi-arid regions characterized by erratic rainfall. This study evaluates a novel technique for assessing the impact of drought on LULC variations in the context of climate change from 2018 to 2022. Various data sources were harnessed, encompassing Sentinel-2 satellite imagery for LULC classification, climate data from the CHIRPS and AgERA5 databases, geomorphological data from JAXA's ALOS satellite, and a drought indicator (Vegetation Health Index (VHI)) derived from MODIS data. Two classifier models, namely gradient tree boost (GTB) and random forest (RF), were trained and assessed for LULC classification, with performance evaluated by overall accuracy (OA) and kappa coefficient (K). Notably, the GTB model exhibited superior performance, with OA > 90% and a K > 0.9. Over the period from 2018 to 2022, Fez experienced LULC changes of 19.92% expansion in built-up areas, a 34.86% increase in bare land, a 17.86% reduction in water bodies, and a 37.30% decrease in agricultural land. Positive correlations of 0.81 and 0.89 were observed between changes in agricultural LULC, rainfall, and VHI. Furthermore, mild drought conditions were identified in the years 2020 and 2022. This study emphasizes the importance of AI and remote sensing techniques in assessing drought and environmental changes, with potential applications for improving existing drought monitoring systems.

The prevalence of headache in the adult population of Morocco: a cross-sectional population-based study.

BACKGROUND: The series of population-based studies conducted by the Global Campaign against Headache has, so far, included Pakistan and Saudi Arabia from the Eastern Mediterranean Region. The Maghreb countries of North Africa, also part of this Region, are geographically apart and culturally very different from these countries. Here we report a study in Morocco. METHODS: We applied the standardised methodology of Global Campaign studies, with cluster-randomized sampling in regions of Morocco selected to be representative of its diversities. In three of these regions, in accordance with this methodology, we made unannounced visits to randomly selected households and, from each, interviewed one randomly selected adult member (aged 18-65 years) using the HARDSHIP structured questionnaire translated into Moroccan Arabic and French. In a fourth region (Fès), because permission for such sampling was not given by the administrative authority, people were randomly stopped in streets and markets and, when willing, interviewed using the same questionnaire. This was a major protocol violation. RESULTS: We included 3,474 participants, 1,074 (41.7%) from Agadir, 1,079 (41.9%) from Marrakech, 422 (16.4%) from Tétouan and 899 from Fès. In a second protocol violation, interviewers failed to record the non-participating proportion. In the main analysis, excluding Fès, observed 1-year prevalence of any headache was 80.1% among females, 68.2% among males. Observed 1-day prevalence (headache yesterday) was 17.8%. After adjustment for age and gender, migraine prevalence was 30.8% (higher among females [aOR = 1.6]) and TTH prevalence 32.1% (lower among females [aOR = 0.8]). Headache on ≥ 15 days/month (H15+) was very common (10.5%), and in more than half of cases (5.9%) associated with acute medication overuse (on ≥ 15 days/month) and accordingly diagnosed as probable medication-overuse headache (pMOH). Both pMOH (aOR = 2.6) and other H15+ (aOR = 1.9) were more common among females. In the Fès sample, adjusted prevalences were similar, numerically but not significantly higher except for other H15+. CONCLUSIONS: While the 1-year prevalence of headache among adults in Morocco is similar to that of many other countries, migraine on the evidence here is at the upper end of the global range, but not outside it. H15 + and pMOH are very prevalent, contributing to the high one-day prevalence of headache.

Gender and Body Mass Index Difference in Aerobic Capacity: A Study in Moroccan High School Students.

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.
