Assessment of the impact of COVID-19 and political instability on mental health of university students in Sudan.

Background: The mental health of students plays a crucial role in their learning and performance. The COVID-19 pandemic, the political turmoil and a coup in Sudan has exacerbated stress and anxiety among university students in Sudan due to uncertainty about their academic activities.

Aim: To assess post-traumatic stress disorder (PTSD) occurrence and coping strategies adopted by university students in Sudan.

Knowledge, Perception, and Self-Confidence of Antibiotic Resistance, Appropriate Antibiotic Therapy, and Antibiotic Stewardship Among Undergraduate Pharmacy Students in Sudan.

Background: Adequate training in infectious diseases and antibiotic resistance is crucial for pharmacy students to participate in antibiotic stewardship programs and understand microbiology careers.

Aim: The study was carried out to assess the knowledge and self-reported confidence in antibiotic resistance, antibiotic therapy, and antimicrobial stewardship (AMS) among final-year undergraduate pharmacy students in Sudan.

Methods: A cross-sectional study was conducted in three universities using a 57-item online questionnaire between April and May 2022.

Trends of Coagulation Parameters in Human Immunodeficiency Virus Patients.

HIV disease is recognized to cause inconsistencies in coagulation via various pathways during infection. Some studies have indicated that HIV-infected patients are prone to developing thrombocytopenia, thrombosis, or autoantibodies that may cause difficulties in diagnosis. This study is intended to measure the trend of coagulation parameters in Sudanese patients with HIV.

Potential Therapeutic Target and Vaccines for SARS-CoV-2.

The coronavirus has become the most interesting virus for scientists because of the recently emerging deadly SARS-CoV-2. This study aimed to understand the behavior of SARS-CoV-2 through the comparative genomic analysis with the closest one among the seven species of coronavirus that infect humans. The genomes of coronavirus species that infect humans were retrieved from NCBI, and then subjected to comparative genomic analysis using different bioinformatics tools.

Analysis: HLA-DRB1 Gene's Variants and Their Clinical Impact.

The gene encodes a protein that is essential for the immune system. This gene is important in organ transplant rejection and acceptance, as well as multiple sclerosis, systemic lupus erythematosus, Addison's disease, rheumatoid arthritis, caries susceptibility, and Aspirin-exacerbated respiratory disease. The following variants were investigated: single-nucleotide variants (SNVs), multi-nucleotide variants (MNVs), and small insertions-deletions (Indels) in the gene via coding and untranslated regions.

Comparative Genomic Analysis of Multi-Drug Resistant Sequence Type 235 Isolated from Sudan.

) is known to be associated with resistance to practically all known antibiotics. This is a cross-sectional, descriptive, laboratory-based analytical study in which 200 clinical isolates were involved. The DNA of the most resistant isolate was extracted and its whole genome was sequenced, assembled, annotated, and announced, strain typing was ascribed, and it was subjected to comparative genomic analysis with two susceptible strains.

Detection of Nonsynonymous Single Variants in Human HLA-DRB1 Exon 2 Associated with Renal Transplant Rejection.

: HLA-DRB1 is the most polymorphic gene in the human leukocyte antigen (HLA) class II, and exon 2 is critical because it encodes antigen-binding sites. This study aimed to detect functional or marker genetic variants of HLA-DRB1 exon 2 in renal transplant recipients (acceptance and rejection) using Sanger sequencing. : This hospital-based case-control study collected samples from two hospitals over seven months.

Prevalence and Predictors of Antibiotic Self-Medication in Sudan: A Descriptive Cross-Sectional Study.

Background: Self-medication with antibiotics (SMA) is one of the common factors which precipitate antimicrobial resistance, yet if effective implementations are amended it can be effortlessly controlled. The present study aimed to estimate the prevalence and predictors of SMA in Sudan.

Methods: The study adopted a cross-sectional study design conducted in all Sudan states between June and December 2021.

NeoCoV Is Closer to MERS-CoV than SARS-CoV.

Recently, Coronavirus has been given considerable attention from the biomedical community based on the emergence and isolation of a deadly coronavirus infecting human. To understand the behavior of the newly emerging MERS-CoV requires knowledge at different levels (epidemiologic, antigenic, and pathogenic), and this knowledge can be generated from the most related viruses. In this study, we aimed to compare between 3 species of Coronavirus, namely Middle East Respiratory Syndrome (MERS-CoV), Severe Acute Respiratory Syndrome (SARS-CoV), and NeoCoV regarding whole genomes and 6 similar proteins (E, M, N, S, ORF1a, and ORF1ab) using different bioinformatics tools to provide a better understanding of the relationship between the 3 viruses at the nucleotide and amino acids levels.

Development of an immunoaffinity solid phase microextraction method for the identification of penicillin binding protein 2a.

Methicillin resistant Staphylococcus aureus (MRSA) is a bacterium that is resistant to many antibiotics. Resistance to methicillin is related to production of penicillin binding protein 2a (PBP2a). The currently presented research involves the development of antibody-linked immunoaffinity solid phase microextraction (SPME) sorbents characterized from several aspects that can identify protein PBP2a.
