Association study of the JAK/STAT signaling pathway with susceptibility to COVID-19 in moroccan patient and in-silico analysis of rare variants.

The goal of our study was to explore the association of the polymorphisms in the JAK/STAT pathway among Moroccan COVID-19 patients, using a case-control approach. Next-generation sequencing was employed to investigate the IFNAR1, IFNAR2, JAK1, TYK2, STAT2, and IRF9 genes within the JAK/STAT pathway. We also performed an in silico study to examine the rare variants in this pathway.

Adenomatous Polyposis Coli (APC) Promoter Gene Methylation in Urine-Derived DNA: A Non-invasive Biomarker for Early Bladder Cancer Detection and Tumor Aggressiveness.

Background Bladder urothelial carcinoma (BLCA) is a major cause of morbidity and mortality worldwide, largely due to the high frequency of disease relapse and the lack of efficient endoscopic diagnostic methods. This study aimed to address this clinical gap by evaluating the potential of using adenomatous polyposis coli (APC) gene promoter methylation as a biomarker detectable in urine DNA of individuals with BLCA. Methods Methylation-specific PCR was used to determine the methylation status of the APC promoter gene in 50 bladder carcinoma patients and 50 apparently healthy individuals.

, and Mutational Profile of Colorectal Cancer in a Series of Moroccan Patients.

Objectives: The present study aimed to evaluate the frequencies of , and mutations and their possible associations with clinicopathological features in 249 Moroccan patients with colorectal cancer (CRC).

Methods: A retrospective investigation of a cohort of formalin-fixed paraffin-embedded tissues of 249 patients with CRC was screened for // mutations using Idylla™ technology and pyrosequencing.

Results: , and mutations were revealed in 46.

Prevalence and patterns of mutations in RAS/RAF/MEK/ERK/MAPK signaling pathway in colorectal cancer in North Africa.

Background: Our review discuss (i) the findings from analyzed data that have examined KRAS, NRAS and BRAF mutations in patients with colorectal cancer (CRC) in North Africa and to compare its prevalence with that shown in other populations and (ii) the possible role of dietary and lifestyle factors with CRC risk.  METHODS: Using electronic databases, a systematic literature search was performed for the KRAS, NRAS, and BRAF mutations in CRC patients from Morocco, Tunisia, Algeria and Lybia.  RESULTS: Seventeen studies were identified through electronic searches with six studies conducted in Morocco, eight in Tunisia, two in Algeria, and one in Libya.

Reactivation of cytomegalovirus in a patient with stevens-johnson syndrome-toxic epidermal necrolysis.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe adverse cutaneous reactions to drugs. We describe the case of a 19 year old patient with SJS/TEN overlap syndrome, who developed severe interstitial pneumonia after she had received antiepileptic drugs. A cytomegalovirus infection was diagnosed by Real Time Polymerase Chain Reaction (RT-PCR) detection on Bronchoalveolar lavage.

Factors influencing uptake of influenza vaccine amongst healthcare workers in a regional center after the A(H1N1) 2009 pandemic: lessons for improving vaccination rates.

Background: Vaccination of health-care workers (HCWs) against seasonal influenza has been consistently recommended worldwide in order to prevent nosocomial transmission and ensure delivery of health-care services during outbreaks. Overall, immunization rates were low across all nation, including among HCWs. Little is known about the acceptability and compliance with seasonal influenza vaccine among HCWs after the A(H1N1) 2009 pandemic.
