ABSTRACT

BACKGROUND AND AIMS: The association of the C677T polymorphism of the Methylenetetrahydrofolate Reductase (MTHFR) gene with susceptibility to type 2 diabetes mellitus (T2DM) has been widely debated. Therefore, our aim is to conclusively resolve this controversy in the Middle East and North Africa region population through a meta-analysis. MATERIEL AND METHODS: We identified relevant articles by searching literature databases, such as PubMed, Web of Science, and Science Direct, to retrieve studies that examined the association between the MTHFR C677T polymorphism and the risk of developing T2DM. Using meta-analysis, we calculated the odds ratio (OR) and confidence interval (CI) values of these studies to assess the susceptibility to T2DM related to the C677T polymorphism of MTHFR gene. RESULTS: In this meta-analysis, we included a total of 13 publications comprising 2072 T2DM patients and 2164 control subjects. The results of the meta-analysis suggested that there is a significant association between the C677T polymorphism and T2DM risk in overall comparisons for allele contrasts (T vs C): OR = 1.25, 95% CI = 1.04-1.50, p = 0.015 and homozygous (TT vs CC): OR = 1.44, 95% CI = 1.01-2.05, p = 0.038). Subgroup analysis revealed that the C677T polymorphism is associated with a risk of T2DM in Asian populations, while there is no significant association between this polymorphism and T2DM in Caucasian and African populations. Furthermore, there was no evidence of publication bias. CONCLUSION: Our study's results suggest that the allele contrast of the C677T polymorphism of the MTHFR gene is associated with an increased risk of T2DM in the overall population, particularly among Asians.

ABSTRACT

BACKGROUND AND AIMS: There is tremendous increase in type 2 diabetes mellitus (T2DM) worldwide. The impact of FTO gene polymorphisms on the risk of T2DM is not yet clear because of the controversial results of studies. This meta-analysis aimed to better clarify the association between three FTO gene polymorphisms SNPs (rs9939609, rs8050136 and rs17817449) and T2DM in a larger combined population worldwide. MATERIAL AND METHODS: A comprehensive search on the PubMed, Science Direct, and Web of Science databases was conducted to identify investigations in relationship between different FTO gene polymorphisms (rs9939609, rs8050136 and rs17817449) and T2DM globally. Published papers from January 2007 to May 2023 were collected. Inclusion criteria are limited to human case-control studies published in English and peer-reviewed, which provided data on the genotype distributions of FTO gene polymorphisms and T2DM risk. Odds ratios (OR) and 95% confidence intervals (CI) were calculated to express the results of the meta-analysis. Potential sources of bias and heterogeneity using Egger's regression analysis were also assessed. RESULTS: Of 234695 identified articles, forty-eight studies were selected including 36,051 patients with T2DM and 51,266 control subjects. Overall, we found a significant increased risk of T2DM susceptibility and rs9939609 FTO gene polymorphism in the Allele contrast (A vs. T: OR = 1,30, 95% CI = 1.14; 1.48, P < 0,05, I2 = 0,94), Recessive model (AA vs. AT + TT: OR = 1,54, 95% CI = 1.19; 2.00, P < 0,05, I2 = 0,94), Dominant model (AA + AT vs. TT: OR = 1,26, 95% CI = 1.10; 1.45, P < 0,05, I2 = 0,89), homozygote model (AA vs. TT: OR = 1,60, 95% CI = 1.26; 2.03, P < 0,05, I2 = 0,90), and heterozygote model (AA vs. AT: OR = 1,43, 95% CI = 1.09; 1.88, P = 0,008, I2 = 0,93). we also found a significantly increased risk of T2DM susceptibility and rs8050136 FTO gene polymorphism under all models. For rs17817449 we did not find any association between with T2DM. CONCLUSION: The present meta-analysis confirms that rs9939609 and rs8050136 in the FTO gene are significantly associated with T2DM, while rs17817449 does not show any association.

ABSTRACT

Sexual and reproductive health (SRH) concerns physical, mental, and social well-being as related to sexual and reproductive systems. Self-care, which is the ability to promote health without the support of a health-care provider, can advance SRH, especially for fragile populations. Mobile health (mHealth) solutions can be used to raise awareness about SRH. We performed a structured literature review and analysis of mHealth-based approaches for delivering self-SRH services and interventions in the WHO Eastern Mediterranean Region (EMR). A fuzzy-based framework for assessing those mHealth apps was proposed. We identified 6 out of 737 papers, and 23 (5.7%) out of 400 mHealth apps retrieved from app-stores, describing mHealth use for self SRH with only 10 apps developed in EMR countries, namely Morocco, Pakistan, Egypt, Iran, and Jordan. Our fuzzy-based framework proposes guidelines regarding the implementation of self-care interventions to help project leaders promote their adoption in the SRH systems.

ABSTRACT

Human Mannose-binding lectin (MBL) is a protein encoded by MBL2 gene involved in the activation of the lectin-complement pathway. Several studies emphasized the role of MBL2 gene in several infectious diseases' susceptibility, including HIV-1 infection. We aim to investigate the impact of 10 MBL2 gene polymorphisms located in the promoter, 5'UTR and exon 1 regions on HIV-1 physiopathology. The polymorphisms genotyping of 400 individuals, which 200 were HIV-1 positive patients and 200 were controls, was performed by PCR-sequencing. Our results showed that rs503037 and rs1800451 polymorphisms are associated with a high risk of HIV-1 infection susceptibility while rs7096206 and rs11003123 showed a protective effect. A significant association between haplotype CGA and HIV-1 infection susceptibility was also found in the exon 1 region. Moreover, rs11003124, rs7084554, rs36014597 and rs11003123 polymorphisms revealed an association with treatment response outcome as measured by RNA viral load. This study highlights the importance of MBL2 polymorphisms in the modulation of HIV-1 infection susceptibility and the contribution to treatment response outcomes among Moroccan subjects.

ABSTRACT

Background and Aim: Brucellosis is a prevalent infectious zoonotic disease that affects humans, livestock, and wildlife in many parts of the world. A cross-sectional study was conducted to estimate the seroprevalence and risk factors of brucellosis among farmers and patients attending six health centers in Sidi Kacem province (northwestern Morocco). Materials and Methods: Blood samples (3-5 mL) were collected. Among 1283 participants, 351 were males and 932 were females and tested for Brucella antibodies using rose Bengal plate test and immunoglobulin (Ig)M/IgG enzyme-linked immunosorbent assay (ELISA) for confirmation. Results: The seroprevalence of brucellosis was 33.20% (426/1283) with a higher risk among males and rural residents. The univariable analysis revealed that contacting cattle, handling abortion products and manure, and consuming undercooked beef and goat meat were all risk factors for brucellosis. Furthermore, raw milk and milk derivatives were risk factors strongly linked to brucellosis. Conclusion: Our findings indicate a high prevalence of brucellosis associated with the consumption of raw meat, raw dairy products, milk, and close contact with infected animals. However, there are some limitations to this study, such as we did not use the ELISA test on all sera collected and individuals under the age of 18 were not included in the study. Moreover, building a database on the occurrence of brucellosis and associated epidemiological factors is critical for providing informed advice to policymakers to improve control strategies against this disease in Morocco.

ABSTRACT

Prostate cancer (PCa) is the second most commonly diagnosed in men worldwide and one of the most frequent cancers in men in Africa. The heterogeneity of this cancer fosters the need to identify potential genetic risk factors/biomarkers. Omics variations may significantly contribute to early diagnosis and personalized treatment. However, there are few genomic studies of this disease in African populations. This review sheds light on the status of genomics research on PCa in Africa and outlines the common variants identified thus far. The allele frequencies of the most significant SNPs in Afro-native, Afro-descendants, and European populations were compared. We advocate how these few but promising data will aid in understanding, better diagnosing, and precisely treating this cancer and the need for further collaborative research on the genomics of PCa in the African continent.

ABSTRACT

Early infancy is critical for the development of an infant's gut flora. Many factors can influence microbiota development during the pre- and postnatal periods, including maternal factors, antibiotic exposure, mode of delivery, dietary patterns, and feeding type. Therefore, investigating the connection between these variables and host and microbiome interactions in neonatal development would be of great interest. As the "unculturable" era of microbiome research gives way to an intrinsically multidisciplinary field, microbiome research has reaped the advantages of technological advancements in next-generation sequencing, particularly 16S rRNA gene amplicon and shotgun sequencing, which have considerably expanded our knowledge about gut microbiota development during early life. Using omics approaches to explore the neonatal microbiome may help to better understand the link between the microbiome and newborn diseases. Herein, we summarized the metagenomics methods and tools used to advance knowledge on the neonatal microbiome origin and evolution and how the microbiome shapes early and late individuals' lives for health and disease. The way to overcome limitations in neonatal microbiome studies will be discussed.

ABSTRACT

Introduction: microvascular and macrovascular complications of type 2 diabetes mellitus (T2DM) are one of the major causes of morbidity and mortality worldwide among patients with T2DM. This study aims to estimate the prevalence of these chronic complications and identify the associated risk factors among Moroccan patients with T2DM. Methods: this cross-sectional study was conducted on 505 T2DM patients followed by the healthcare Centers of the Casablanca-Settat region from January 2017 to July 2018. The socio-demographic, anthropometric, biochemical, and clinical data were recorded using a structured survey. For statistical analysis, SPSS version 20 is used. Univariate and multivariate logistic regression analyses are used to determine the risk factors associated with chronic complications of T2DM. Results: among the 505 Moroccan patients with T2DM, 84.98% were women. The average age of the patients was 57.27±10.74 years. Diabetic eye disease was the most frequent complication (29.5%) followed by cardiovascular diseases (CVDs) (22.4%), kidney disease in diabetes (9.8%), diabetes foot (2.8%), and neuropathy (1.8%). Logistic regression analysis showed that the CVDs was associated with hypertension (OR: 2.41; 95% CI: 1.11-5.22; p=0.026), hypolipidemia treatment (OR: 2.20; 95% CI: 1.06-4.59; p=0.034), insulin use (OR= 0.39; 95%CI: 0.15-0.96, p=0.043) and LDL-C (OR: 1.01; 95% CI: 1-1.02; p=0.035) in T2DM patients. However, the major risk factors for the development of kidney disease in T2DM patients were a lack of regular physical activity (OR: 3.77; 95% CI: 1.22-11.67; p=0.021), hypolipidemia treatment (OR: 8.31; 95% CI: 1.86-36.97; p=0.005), and high serum creatinine (OR: 1.33; 95% CI: 1.16-1.53; p≤0.001). In addition, LDL-C levels were found to be a significant risk factor for diabetes eye disease (OR: 1.01; 95% CI: 1.00-1.03; p=0.008). Conclusion: this study shows that the increased duration of diabetes, insulin use, lack of regular physical exercise, hypertension, hypolipidemia treatment, high serum creatinine, and LDL-C were significant risk factors for chronic complications of T2DM in Moroccan patients.

ABSTRACT

BACKGROUND AND AIMS: The association between insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme (ACE) gene and the risk of type 2 diabetes mellitus (T2DM) remains controversial. This study aimed to assess the effect of the ACE I/D gene polymorphism on T2DM in the Middle East and North Africa region (MENA region). MATERIAL AND METHODS: Our data was extracted from PubMed, Science Direct, and the Web of Science. The predefined inclusion criteria included only the human case-control studies of English Peer-reviewed papers containing the data on genotype distributions of ACE I/D polymorphism and the T2DM risk. Review articles, meeting abstracts, editorials, animal studies, and studies not providing genotype distribution data or without sufficient data were excluded from this work. Results of this meta-analysis were expressed using odds ratios (OR) and 95% confidence intervals (CI). Indeed, the potential sources of heterogeneity and bias were examined by the Egger regression. RESULTS: Of 2755 identified articles, 10 studies were selected, including 2710 patients with T2DM and 2504 control subjects. Overall, we found a significant increased risk of T2DM susceptibility and the D allele of ACE I/D gene polymorphism (OR = 1.97; 95% CI = 1.33-2.93, p = 0.0007), recessive (OR = 2.16; 95% CI = 1.27-3.67; p = 0.004), dominant (OR = 2.45; 95% CI = 1.54-3.91; p = 0.0001), homozygote (OR = 3.35; 95% CI = 1.78-6.29; p = 0.0001) and heterozygote comparisons (OR = 1.76; 95% CI = 1.07-2.88; p = 0.024). CONCLUSION: Our result suggests that this polymorphism may contribute to the development of T2DM in the MENA Region. This result needs to be confirmed by future well-designed studies with larger sample sizes in diverse populations and ethnicities.

ABSTRACT

Introduction: the increased prevalence of dyslipidemia in patients with type 2 diabetes mellitus (T2DM) results from uncontrolled hyperglycemia and consistently contributes to an elevated risk of cardiovascular complications. This study sought to estimate the prevalence of dyslipidemia and to investigate the relationship between glycated hemoglobin (HbA1C) and serum lipid levels in Moroccan patients with T2DM. Methods: a total of 505 patients with T2DM were included in this cross-sectional study, 77.4% with chronic complications and 22.6% without. The collected data were examined using statistical package for the social sciences (SPSS) version 20.0 software and appropriate statistical methods. Results: the data analysis showed that the mean and SD of age were 57.27±10.74 years. Among 505 patients with T2DM, the prevalence of hypercholesterolemia, hypertriglyceridemia, increased low-density lipoprotein cholesterol (LDL-C), and decreased HDL-C was 41.4%, 35.9%, 27.1%, and 17%, respectively. In addition, the data analysis showed that levels of total cholesterol (TC) (p≤0.001), triglycerides (p≤0.001), Low-density lipoprotein cholesterol (LDL-C) (p≤0.001), TC/HDL-C ratio (p=0.006), and LDL-C/HDL-C ratio (p=0.006) were significantly higher in T2DM patients with complications as compared to those without complications. The patients with HbA1C > 7.0% had significantly higher values of fasting blood glucose (FBG) (p≤0.001), total cholesterol (p≤0.001), triglycerides (p≤0.001), and TC/HDL-C ratio (p=0.025) as compared to the patients with HbA1C ≤ 7.0%. The HbA1C demonstrated a significant negative correlation with age (r=-0.139), and positive correlation with FBG (r=0.673), total cholesterol (r=0.189) and triglycerides (r=0.243). Conclusion: our results showed that HbA1C is the most important biomarker of long-term glycemic control and can also be a good indicator of the lipid profile.

ABSTRACT

The human transmembrane protease serine 2 (TMPRSS2) protein plays an important role in prostate cancer progression. It also facilitates viral entry into target cells by proteolytically cleaving and activating the S protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In the current study, we used different available tools like SIFT, PolyPhen2.0, PROVEAN, SNAP2, PMut, MutPred2, I-Mutant Suite, MUpro, iStable, ConSurf, ModPred, SwissModel, PROCHECK, Verify3D, and TM-align to identify the most deleterious variants and to explore possible effects on the TMPRSS2 stability, structure, and function. The six missense variants tested were evaluated to have deleterious effects on the protein by SIFT, PolyPhen2.0, PROVEAN, SNAP2, and PMut. Additionally, V160M, G181R, R240C, P335L, G432A, and D435Y variants showed a decrease in stability by at least 2 servers; G181R, G432A, and D435Y are highly conserved and identified posttranslational modifications sites (PTMs) for proteolytic cleavage and ADP-ribosylation using ConSurf and ModPred servers. The 3D structure of TMPRSS2 native and mutants was generated using 7 meq as a template from the SwissModeller group, refined by ModRefiner, and validated using the Ramachandran plot. Hence, this paper can be advantageous to understand the association between these missense variants rs12329760, rs781089181, rs762108701, rs1185182900, rs570454392, and rs867186402 and susceptibility to SARS-CoV-2.

ABSTRACT

SARS-CoV-2 coronavirus uses for entry to human host cells a SARS-CoV receptor of the angiotensin-converting enzyme (ACE2) that catalyzes the conversion of angiotensin II into angiotensin (1-7). To understand the effect of ACE2 missense variants on protein structure, stability, and function, various bioinformatics tools were used including SIFT, PANTHER, PROVEAN, PolyPhen2.0, I. Mutant Suite, MUpro, SWISS-MODEL, Project HOPE, ModPred, QMEAN, ConSurf, and STRING. All twelve ACE2 nsSNPs were analyzed. Six ACE2 high-risk pathogenic nsSNPs (D427Y, R514G, R708W, R710C, R716C, and R768W) were found to be the most damaging by at least six software tools (cumulative score between 6 and 7) and exert deleterious effect on the ACE2 protein structure and likely function. Additionally, they revealed high conservation, less stability, and having a role in posttranslation modifications such a proteolytic cleavage or ADP-ribosylation. This in silico analysis provides information about functional nucleotide variants that have an impact on the ACE2 protein structure and function and therefore susceptibility to SARS-CoV-2.

ABSTRACT

Over the last decade, it has become increasingly apparent that the microbiome is a central component in human well-being and illness. However, to establish innovative therapeutic methods, it is crucial to learn more about the microbiota. Thereby, the area of metagenomics and associated bioinformatics methods and tools has become considerable in the study of the human microbiome biodiversity. The application of these metagenomics approaches to studying the gut microbiome in COVID-19 patients could be one of the promising areas of research in the fight against the SARS-CoV-2 infection and disparity. Therefore, understanding how the gut microbiome is affected by or could affect the SARS-CoV-2 is very important. Herein, we present an overview of approaches and methods used in the current published studies on COVID-19 patients and the gut microbiome. The accuracy of these researches depends on the appropriate choice and the optimal use of the metagenomics bioinformatics platforms and tools. Interestingly, most studies reported that COVID-19 patients' microbiota are enriched with opportunistic microorganisms. The choice and use of appropriate computational tools and techniques to accurately investigate the gut microbiota is therefore critical in determining the appropriate microbiome profile for diagnosis and the most reliable antiviral or preventive microbial composition.

ABSTRACT

BACKGROUND: Leptospirosis is an anthropozoonotic reemerging neglected infectious disease underreported in most developing countries. A cross-sectional study was performed between 17 and 23 February 2014 to estimate the seroprevalence of leptospirosis among high-risk populations in Casablanca (Morocco). METHODS: A total of 490 human serum samples (97.6% males) were collected in 3 high-risk occupational sites including the biggest meat slaughterhouse (n = 208), a poultry market (n = 121), and the fish market (n = 161). A total of 125 human blood samples were also collected from the general population and used in this study as a control group. To detect the presence of anti-Leptospira, sera were screened with in-house IgG and IgM enzyme-linked immunosorbent assay (ELISA). Positive samples were tested by Microscopic Agglutination Technique (MAT) using a panel of 24 serovar cultures and cut point of 1 : 25. RESULTS: Seroprevalence of leptospirosis among the control group was 10.4% (13/125). A high seropositivity among the overall seroprevalence of 24.1% (118/490) was observed in the high-risk groups of which 7.3% (36/490), 13.7% (67/490), and 3.1% (15/490) were for anti-Leptospira IgM, IgG, and both IgG and IgM antibodies, respectively. Most of the positive individuals were occupationally involved in poultry (37.2%), followed by the market fish (26.1%) and the meat slaughterhouse (14.9%) workers. Among all ELISA-positive serum samples, 20.3% (n = 24) had positive MAT responses, of which the Icterohaemorrhagiae (n = 7) is the most common infecting serogroup followed by Javanica (4), Australis (2), and Sejroe, Mini, and Panama (one in each). In the remaining 8 MAT-positive sera, MAT showed equal titers against more than one serogroup. CONCLUSION: Individuals engaged in risk activities are often exposed to leptospiral infection. Therefore, control and prevention policies toward these populations are necessary.

ABSTRACT

During the last century, cancer biology has been arguably one of the most investigated research fields. To gain deeper insight into cancer mechanisms, scientists have been attempting to integrate multi omics data in cancer research. Cancer genomics, transcriptomics, metabolomics, proteomics, and metagenomics are the main multi omics strategies used currently in the diagnosis, prognosis, treatment, and biomarker discovery in cancer. In this review, we describe the use of different multi omics strategies in cancer research in the African continent and discuss the main challenges facing the implementation of these approaches in African countries such as the lack of training programs in bioinformatics in general and omics strategies in particular and suggest paths to address deficiencies. As a way forward, we advocate for the establishment of an "African Cancer Genomics Consortium" to promote intracontinental collaborative projects and enhance engagement in research activities that address indigenous aspects for cancer precision medicine.

ABSTRACT

Hepatitis C virus (HCV) infection and type 2 diabetes mellitus (T2DM) present a significant health burden, with increasing complications and mortality rates worldwide. Pycnogenol® (PYC), a natural product, possesses antidiabetic and antiviral properties that may improve HCV-associated T2DM. In this review, we present previously published data on the effectiveness of PYC against HCV replication and T2DM. We believe that supplementing conventional treatment with PYC may improve the current HCV therapy, attenuate HCV-associated T2DM, and reduce the risk of complications such as cirrhosis or hepatocellular carcinoma and cardiovascular disease.

ABSTRACT

STUDY OBJECTIVE: Human papillomavirus (HPV) infection is estimated to play an etiologic role in 99.7% of cervical cancer. Vaccines can prevent up to 70% of the cervical cancer caused by HPV 16 and 18. The present study was designed to define the knowledge of HPV and HPV vaccine acceptability among Moroccan youth. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: A nationwide anonymous questionnaire with a sample of 688 adolescents (12-17 years) and 356 young adults (18-30 years) was organized, that asked about HPV, origin of cervical cancer, Papanicolaou (Pap) test, and acceptability of HPV vaccine. Data were analyzed using univariate and multivariate logistic regression methods. RESULTS: Overall, a low frequency (213/1044 = 20%) of HPV knowledge was observed among the studied population. A multivariate model analysis showed that age, educational level, and knowledge of the Pap test remained significantly associated factors with HPV knowledge. Additionally, only 27% (282/1044) of participants were willing to accept HPV vaccination. Highest acceptability was observed among young adults compared with adolescents (166/356 = 46.6% vs 116/688 = 16.9%). Sixty-two percent (103/165) of male participants accepted the HPV vaccine compared with only 20.4% (179/879) of female participants. Educational level, type of school, and knowledge of the Pap test were associated factors with HPV vaccine acceptability in a multivariate model analysis. CONCLUSION: The present study showed a low level of HPV knowledge and HPV vaccine acceptability among Moroccan youth. Promotion of activities and sensitization are required to maximize public awareness in the future. This objective can be achieved with the use of media, active efforts by health care providers, and introduction of sexual education in school programs.
