Knowledge and Attitudes Toward Premarital Screening Programs Among Students at the University of Tripoli, Libya.

Background: Despite the increase in hereditary disease in Arab countries due to the high rates of consanguineous marriages, research on community awareness of premarital screening (PMS) for disease carriers is still scarce.

Aim: To investigate knowledge and attitudes toward genetic PMS programs among university students in Libya.

Methods: A cross-sectional study was conducted using a self-administered questionnaire distributed to 421 Libyan students aged 18-25 years at the University of Tripoli.

Analysis of BRCA1 germline variants (exons 5, 11 and 20) in breast cancer families from Libya.

Breast cancer (BC) is a leading cause of cancer deaths in Libyan women. variants differ globally due to the diversity of genetic makeup and populations history. Their distribution, prevalence, and significance in Libyans remain largely unexplored.

Prevalence of multi-drug resistant bacteria in intensive care units at Tripoli University Hospital, Tripoli, Libya.

Among hospitalized patients worldwide, infections caused by multidrug-resistant (MDR) bacteria are a major cause of morbidity and mortality. This study aimed to isolate MDR bacteria from five intensive care units (ICUs) at Tripoli University Hospital (TUH). A prospective cross-sectional study was conducted over a seven-month period (September 2022 to March 2023) across five ICUs at TUH.

Expression of Cathepsin D in early-stage breast cancer and its prognostic and predictive value.

Purpose: Cathepsin D is a proteolytic enzyme that is normally localized in the lysosomes and is involved in the malignant progression of breast cancer. There are conflicting results regarding Cathepsin D significance as prognostic and predictor marker in breast cancer. This study aimed to evaluate the expression and prognostic significance of Cathepsin D in early-stage breast cancer.

Single ChAdOx1 nCoV-19 dose elicits stronger immune response in previously infected individuals than in SARS-CoV2 naive persons.

Background: Current vaccines against COVID-19 effectively reduce morbidity and mortality and are vitally important for controlling the pandemic. Between December 2020 and February 2021, adenoviral vector vaccines such as ChAdOx1 (AstraZeneca-Oxford) were put in use. Recent reports demonstrate robust serological responses to a single dose of messenger RNA vaccines in individuals previously infected with SARS-CoV-2.

Impact of vaccination and risk factors on COVID-19 mortality amid delta wave in Libya: A single center cohort study.

Introduction: The Delta variant has led to a surge in COVID-19 cases in Libya, making it crucial to investigate the impact of vaccination on mortality rates among hospitalized patients and the critically ill. This study aimed to explore the risk factors for COVID-19 mortality and the mortality rates among unvaccinated and vaccinated adults during the Delta wave who were admitted to a single COVID-19 care center in Tripoli, Libya.

Methods: The study involved two independent cohorts (n = 341).

Screening of interleukin 17F gene polymorphisms and eight subgingival pathogens in chronic periodontitis in Libyan patients.

Chronic periodontitis (CP) is triggered by periodontal pathogens influenced by genetic and environmental factors. Recent studies have suggested that anti-inflammatory cytokines such as interleukin 17 (IL-17) play a prominent role in the pathogenesis of CP. This study aimed to investigate the association between eight sub-gingival pathogens and interleukin 17F (IL-17F) gene single nucleotide polymorphisms with CP among Libyans.

Myopericarditis After BNT162b2 mRNA Vaccination With Incidental Intramyocardial Bridging.

Myocarditis and pericarditis are inflammatory conditions affecting the myocardium and pericardium, respectively. They are caused by infectious and non-infectious conditions, including autoimmune disorders, drugs, and toxins. Vaccine-induced myocarditis has been reported with viral vaccines, including influenza and smallpox.

Anti-SARS-CoV-2 IgG Antibodies Post-COVID-19 or Post-Vaccination in Libyan Population: Comparison of Four Vaccines.

Measurement of strength and durability of SARS-COV-2 antibody response is important to understand the waning dynamics of immune response to both vaccines and infection. The study aimed to evaluate the level of IgG antibodies against SARS-CoV-2 and their persistence in recovered, naïve, and vaccinated individuals. We investigated anti-spike RBD IgG antibody responses in 10,000 individuals, both following infection with SARS-CoV-2 and immunization with SARS-COV-2 AstraZeneca, Sputnik V, Sinopharm, and Sinovac.

Variant-specific RT-qPCR for rapid screening of B.1.617 mutations in SARS-CoV-2.

The continuous emergence of new SARS-CoV-2 variants required rapid and reliable diagnostic methods for early detection and monitoring of the spread of the virus, especially in low-resource countries where whole genome sequencing is not available. We aimed to evaluate and compare the performance of two different RT-qPCR screening assays for the detection of B.1.

Warfarin pharmacogenomics in African populations: the importance of ethnicity-based algorithms.

Tweetable abstract It is well accepted that pharmacogenomics (PGx) information from Asia and Europe should not be applied to Africa. More work is needed on different ethnic groups to generate population-specific algorithms that can be used effectively and safely.

Parents' concerns and attitudes towards school reopening during COVID-19 pandemic: a cross-sectional survey-Tripoli, Libya, 2021.

The issue of school reopening has raised several concerns; therefore, the parent's opinion is essential to consider. This study aimed to evaluate the parent's attitudes and concerns toward school reopening in the COVID-19 era. A cross-sectional survey was performed using in-person self-administered questionnaires, the data was collected in the period between January and April 2021 covering parents' concerns and attitudes toward school reopening.

Whole-genome sequencing of SARS-COV-2 showed wide spread of B.1.525 in February 2021 in Libya.

Alpha (B.1.1.

Travel during COVID-19 pandemic in Libya: reasons of travel, disease importation and travel regulations.

Restriction of mobility between countries is an important regulatory measure to combat pandemics such as the coronavirus disease 2019 (COVID-19). Currently, PCR testing is required to enter the Libyan borders. However, no post-travel quarantine is employed.

Time scale performance of rapid antigen testing for SARS-CoV-2: Evaluation of 10 rapid antigen assays.

There is a great demand for more rapid tests for SARS-CoV-2 detection to reduce waiting time, boost public health strategies for combating disease, decrease costs, and prevent overwhelming laboratory capacities. This study was conducted to assess the performance of 10 lateral flow device viral antigen immunoassays for the detection of SARS-CoV-2 in nasopharyngeal swab specimens. We analyzed 231 nasopharyngeal samples collected from October 2020 to December 2020, from suspected COVID-19 cases and contacts of positive cases at Biotechnology Research Center laboratories, Tripoli, Libya.

Association between vitamin D receptor gene polymorphisms and chronic periodontitis among Libyans.

Background: Chronic periodontitis (CP) is a common oral disease characterized by inflammation in the supporting tissue of the teeth 'the periodontium', periodontal attachment loss, and alveolar bone loss. The disease has a microbial etiology; however, recent findings suggest that the genetic factors, such as vitamin D receptor (VDR) gene polymorphisms, have also been included.

Aim: Investigation of the relationship between VDR gene polymorphisms and CP among Libyans.
