Immunotherapy in thymic epithelial tumors: an attractive dilemma.

Thymomas and thymic carcinomas are the most prevalent tumors that develop in the thymus's epithelial tissue. Thymomas are malignant tumors that develop from the epithelial cells of the thymus and frequently include mixed populations of lymphocytes. In contrast, thymic carcinomas are also tumors of the thymic epithelium, but they are characterized by a lack of lymphocytes, exhibit more aggressive behavior, and are associated with a poorer prognosis.

Access to specialist plastic surgery in rural vs. Urban areas of Africa.

Introduction: Plastic surgery is an essential yet underdeveloped field in many African nations, especially in rural areas. The demand for plastic surgery is increasing, but differences in access to respective services between rural and urban domiciles remain ever existent, despite the exponentiation of trauma, burns, and congenital disorders. According to this review, urban areas have access to better facilities and specialized surgeons, while rural areas frequently lack infrastructure, educated healthcare personnel, and medical resources.

Addressing Pre-exposure Prophylaxis Awareness and Knowledge Gaps Among Lebanese Medical Professionals: A Cross-Sectional Study.

Objective: In Lebanon, HIV prevalence among key populations such as men who have sex with men is high at 12%, warranting a need for targeted healthcare efforts. Pre-exposure prophylaxis (PrEP) is an effective prevention measure, yet global challenges persist, including limited awareness of PrEP among healthcare professionals. This study investigates PrEP awareness within the Lebanese medical community.

Design: Retrospective study.

Update on Management of Retinopathy of Prematurity: A Review.

Retinopathy of prematurity (ROP) remains a significant health care concern in neonatal care as advances in neonatal intensive practices have improved the survival rates of premature infants. The management and screening of ROP have evolved significantly, with notable trends and advancements aimed at improving outcomes. The use of intravitreal antivascular endothelial growth factor injections has emerged as a prominent initial treatment for ROP in addition to laser photocoagulation.

Muscle fat infiltration: a narrative review of the magnetic resonance (MR)-based evaluation methods and their clinical applications.

Background And Objective: Muscle fat infiltration (MFI) can be seen in several pathologies of various origin including neuromuscular, endocrinological, or musculoskeletal etiologies. Its evaluation is possible through medical imaging, especially MRI, using qualitative or quantitative methods. This paper is an overview of the techniques used to evaluate MFI in different pathologies.

Analysis of the content of YouTube videos discussing acne, psoriasis, and anti-aging skincare in Arabic.

An increasing number of patients turn to YouTube for medical information, driving the growth of research on medical video content, including in dermatology. The objective was to analyze the content of YouTube videos discussing acne, psoriasis, or anti-aging skincare in Arabic. This infodemiological study analyzed the most viewed videos on these topics.

Olive mill wastewater treatment using coagulation/flocculation and filtration processes.

Olive mill wastewater (OMWW), a pollutant resulting from the olive oil industry, poses a serious ecological challenge due to its high pollution load. This effluent is highly concentrated in chemical oxygen demand (COD), which is 200 times higher than that of sewage wastewater. Moreover, OMWW is characterized by a strong acidity, high content of fatty matter, and high concentration of phenolic compounds.

Impact of the COVID-19 pandemic on sexually transmitted infection testing and diagnosis in Lebanon: A retrospective chart review.

Background: Social distancing restrictions during the COVID-19 pandemic caused disruptions to sexual health services (SHS) worldwide. During the first year of the pandemic, Lebanon implemented multiple lockdowns during which SHS endured repetitive closures. We explore the impact of the pandemic on SHS delivery and the diagnosis rate of sexually transmitted infections (STIs) among attendees of a large sexual health clinic in Beirut, Lebanon.

Impact of pay-for-performance on hospital readmissions in Lebanon: an ARIMA-based intervention analysis using routine data.

Background: The objective of this paper was to estimate the impact of country-wide hospital pay-for-performance on readmissions for a set of common conditions in Lebanon.

Methods: This retrospective cohort study included all hospitalizations under the coverage of the Ministry of Public Health in Lebanon between 2011 and 2019. We calculated 30-day all-cause readmissions following general, pneumonia, cholecystectomy and stroke cases.

Modified neuroimmune processes and emotional behaviour in weaned and late adolescent male and female mice born via caesarean section.

Elective and emergency Caesarean section (C-section) procedures are on the rise, exceeding the recommended guidelines by the World Health Organization. Higher morbidities and long-term health conditions are correlated to C-section deliveries, including neurodevelopmental disorders. During C-section delivery, newborns are not exposed to the vaginal commensal flora, which impedes the early establishment of the gut microbiota.

A novel nonsense variant in expanding the spectrum of White-Sutton syndrome: A case report.

White-Sutton Syndrome (WHSUS) is a rare neurodevelopmental genetic disorder with an autosomal dominant mode of inheritance. Truncating mutations in pogo transposable element with zinc finger domain () gene have been reported in cases of WHSUS. In this article, we present the first diagnosed case of WHSUS in Lebanon.

Does the positioning of the patient in the EOS machine affect the validity of cervical and head parameters calculated on whole-spine radiographs?

The aim was to study the validity of free-standing position using modifiers for assessing cervical spine alignment. A total of 26 asymptomatic subjects (45 ± 11years) and 13 with spinal deformities (30 ± 21years) underwent lateral radiographs using EOS®, while adopting 3 different positions, in 2 sequences, without mirror and then with mirror (m) placed in front of them: first, the neutral standing position (upper extremities positioned on the sides of the body, P1 and P1m), then free-standing (P2 and P2m) and modified free-standing (P3 and P3m) positions (shoulders flexed at 90° and fingers placed on clavicles then cheeks, respectively). Participants were asked not to move their trunk and shoulders when moving from P1 to P2 and then P3.

Complex karyotypes in hematologic disorders: a 12-year single-center study from Lebanon.

Conventional cytogenetic analysis is an important tool for the diagnosis of many hematologic disorders (HD). A karyotype is designed as « complex » when several alterations are detected. However, there is no clear consensus on the exact definition of a complex karyotype (CK), and there is a lack of studies that exclusively analyze CK in the literature.
