Salmonella-related foodborne illness is a significant public health concern, with the primary source of human infection being animal-based food products, particularly chicken meat. Lebanon is currently experiencing a dual crisis: the COVID-19 pandemic and an unprecedented economic crisis, which has resulted in substantial challenges to the public health system and food safety. This study aims to assess the prevalence and antibiotic resistance profile of Salmonella in raw poultry meat sold in North Lebanon during this dual crisis.

As part of Qatar's efforts to monitor and combat the spread of infectious diseases during the FIFA World Cup Qatar 2022â„¢ (FWC'22), wastewater surveillance was used to monitor the spread of SARS-CoV-2, human enterovirus, and poliovirus. The screening covered five major wastewater treatment plants servicing the event locations between October 2022 and January 2023.

Toxoplasma gondii is a cosmopolitan protozoan parasite that has a wide range of intermediate hosts. It infects all warm-blooded animals, including humans and birds. The latter typically pick up the infection by ground feeding, and people can contract the parasite from eating undercooked chicken meat.

Nonresponders often require functional endoscopic sinus surgery (FESS) and represent a challenging population potentially due to non-type 2 pathophysiology. This study characterizes the histopathologic features of biologic nonresponders.

Materials And Methods: A dual institutional case-control study examined multiple SBD's and encephaloceles on the risk of CSF leak and postoperative failures post-repair.
Objective: To analyze clinical and radiographic features that may impact the rate of focal hyperostosis (FH) on computed tomography (CT) for primary and recurrent sinonasal inverted papillomas (IPs) as well as highlight factors that may affect concordance between FH and IP true attachment point (TAP).
Methods: All IPs resected between 2006 and 2022 were retrospectively reviewed. CTs were read by a neuroradiologist blinded to operative details.

Background: A number of physical, emotional, cognitive and psychological changes shape the adolescence phase, which may influence health and well-being. Therefore, it is important to develop healthy eating habits that will persist into adulthood.
Objective: This study was conducted in order to investigate in depth the association between components of the Mediterranean diet (MD) and health-related quality of life (HRQoL), along with its different subscales, among Lebanese adolescent students attending schools in Tripoli, North Lebanon.
Analyzing lipid assemblies, including liposomes and extracellular vesicles (EVs), is challenging due to their size, diverse composition, and tendency to aggregate. Such vesicles form with a simple phospholipid bilayer membrane, and they play important roles in drug discovery and delivery. The use of mass spectrometry (MS) allows for broad analysis of lipids from different classes; however, their release from the higher order structural aggregates is typically achieved by chemical means.

Here, we investigated parasitic contamination of leafy green vegetables sold in local markets in the Tripoli district, Lebanon, during two consecutive autumn seasons (2020-2021). The study involved the microscopic examination of 300 samples of five different types of vegetables (60 samples per type) and used standardized qualitative parasitological techniques for some protozoa and helminths.

Objective: Endoscopic sinus surgery (ESS) and endoscopic skull base surgery (ESBS) approaches have revolutionized the management of sinonasal and intracranial pathology. Maintaining surgical hemostasis is essential as bleeding can obscure the visibility of the surgical field, thus increasing surgical duration, risk of complications, and procedural failure. Tranexamic acid (TXA) acts to reduce bleeding by inhibiting fibrin degradation.

Background: Adult and elderly patients with chronic rhinosinusitis (CRS) undergo similar therapeutic management. Few studies have undertaken sinonasal tissue-level comparisons of these groups. This study examines histopathological differences between adults (>18, <65 years) and the elderly (≥65 years) with CRS, with the goal of optimizing medical management.

A cross-sectional study was carried out between April 2020 and August 2021. Blood samples were collected from 260 household cats recruited in different clinics in North and Mount Lebanon, with the aim of determining the seroprevalence of feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV). The seroprevalence reported reached 18.

Data from Lebanon are scarce regarding the seroprevalence of infection in livestock. This study aimed to estimate the seroprevalence and assess the associated risk factors of infection in sheep and goats in Lebanon.

A case-control study was carried out between June 2019 and April 2020 to examine the correlation between RPL
and inherited thrombophilia (IT), namely mutations in factor V Leiden (FVL G1691A), prothrombin (FII G20210A),
and methylenetetrahydrofolate reductase (MTHFR C677T). A total of 120 Lebanese women with RPL was studied
and compared, for the frequency of these mutations, to 100 healthy reproductive Lebanese women.

Due to its geographical proximity to the Syrian conflict and the occupied territories, Lebanon has experienced an influx of refugees in recent times. Palestinian refugees are an identified key vulnerable population, with displaced communities increasingly experiencing camp insecurity, vulnerability to drug use and related health harms. A qualitative study consisting of in-depth interviews and focus group discussions (FGDs) was undertaken as part of a regional exercise investigating Palestinian community experiences of substance and drug use in refugee camps.
