Background: Sickle cell disease, a debilitating, inherited haemolytic anaemia with premature morbidity and mortality, affects millions globally. Mitapivat, a first-in-class, oral, allosteric activator of pyruvate kinase, improves red blood cell survival by increasing ATP and diminishes sickling by decreasing 2,3-diphosphoglycerate. We aimed to evaluate the efficacy and safety of mitapivat in patients with sickle cell disease.

Department of Internal Medicine, American University of Beirut Medical Center, Beirut, Lebanon.

Patients with β-thalassemia continue to have several unmet needs. In non-transfusion-dependent patients, untreated ineffective erythropoiesis and anemia have been associated with a variety of clinical sequelae, with no treatment currently available beyond supportive transfusions. In transfusion-dependent forms, lifelong transfusion and iron chelation therapy are associated with considerable clinical, psychological, and economic burden on the patient and health care system.

The incidence of metabolic dysfunction-associated steatotic liver disease (MASLD) has reached an epidemic rise worldwide. The disease is a constellation of a broad range of metabolic and histopathologic abnormalities. It begins with hepatic steatosis and progresses to metabolic dysfunction-associated steatohepatitis (MASH), including hepatic fibrosis, apoptosis, and cell injury.

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.

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.

Objectives: In this work, which forms part of a larger study of a longitudinal intervention focused on empowering Community Mental Health Workers in a humanitarian context, we examine changes in and correlates of well-being of refugees as a result of discriminatory practices by the State, with comparisons motivated by a mechanistic model of well-being.

Design: This cohort study examines well-being at a single follow-up time as predicted by baseline characteristics in response to a changing social conditions including security raids on our participants; the parent interventional randomised trial focuses on a population of youth in a refugee context, but the present work precedes the main intervention period.

Setting: Refugee populations are among the most vulnerable globally, and the total refugee population is growing dramatically.

The COVID-19 pandemic had an unprecedented impact on healthcare systems and exists globally. To control pandemic progression, COVID-19 vaccines were developed and licensed for use in the adult population in early 2021 and became available in paediatric cohorts several months later. Since then, several studies have reported adverse events and severe adverse events in the adult and paediatric cohorts.

Unveiling the fate and potential neuroprotective role of neural stem/progenitor cells in multiple sclerosis.

Front Neurol

November 2024

Department of Experimental Pathology, Immunology, and Microbiology, American University of Beirut, Beirut, Lebanon.

Article Synopsis
  • Chronic pathological conditions can lead to systemic inflammation, which plays a significant role in the development of neuroinflammatory diseases like Multiple Sclerosis (MS), characterized by damage to myelin and cognitive impairments.
  • The review emphasizes the importance of neural stem cells (NSCs) and neural progenitor cells (NPCs) in the regeneration process through mechanisms called adult neurogenesis (ANG) and gliogenesis, highlighting how these processes can help in recovery from MS.
  • Additionally, the text examines how MS alters the fate of NSCs and NPCs, discussing potential therapeutic interventions that could mitigate cognitive decline and disease progression in MS patients.

Estrogen administration enhances the adverse effects of cigarette smoking on the heart in cycling female mice.

Biol Sex Differ

December 2024

Department of Pharmacology and Toxicology, American University of Beirut Faculty of Medicine, American University of Beirut & Medical Center, Riad El-Solh, Beirut, 11072020, Lebanon.

Article Synopsis
  • - Smoking, especially chronic smoking, poses a significant health risk by increasing the chances of heart-related diseases and causing damage to the heart's structure and function through oxidative stress and endothelial dysfunction.
  • - This study examines how chronic cigarette smoke interacts with the oral contraceptive ethinylestradiol in premenopausal females, revealing that their combination leads to negative changes in heart structure, such as larger left ventricular size and increased heart mass.
  • - Results indicate that this combination triggers an inflammatory response, with elevated inflammatory markers and collagen deposition, suggesting it may lead to heart conditions similar to dilated cardiomyopathy.

Article Synopsis
  • - The increasing number of older people in low- and middle-income countries (LMICs) facing humanitarian crises highlights the urgent need to understand their health and well-being amidst these challenges.
  • - A scoping review analyzing 84 studies revealed that older populations suffer predominantly from mental health issues, such as depression and PTSD, alongside significant physical health concerns, including high mortality rates and limited healthcare access.
  • - Key gaps in research include a lack of focus on contextualized interventions for mental health, under-explored chronic diseases, and the impact of communicable diseases beyond COVID-19, indicating a need for more comprehensive studies.

Chimeric antigen receptor (CAR)-T-cell therapy has revolutionized cellular immunotherapy, demonstrating remarkable efficacy in hematological cancers. However, its application in solid tumors faces significant challenges, including limited T-cell infiltration and tumor-induced immunosuppression. Given the prominent role of macrophages in the tumor microenvironment, their phenotypic plasticity and inherent antitumor properties, such as phagocytosis, offer a promising avenue for therapeutic intervention.

Objective: This study proposed to investigate the cross-sectional and longitudinal associations of menopausal status with physiologic brain magnetic resonance imaging measures.

Methods: The sample included women from the Coronary Artery Risk Development in Young Adults study who self-reported their reproductive histories and participated in the brain magnetic resonance imaging substudies at the year 25 (n = 292) and year 30 (n = 258) follow-up examinations. Menopausal status was classified based on natural menstrual cycle regularity/cessation at both time points.
