The limited self-repair capacity of cartilage due to its avascular and aneural nature leads to minimal regenerative ability. Autologous chondrocyte transplantation (ACT) is a popular treatment for cartilage defects but faces challenges due to chondrocyte dedifferentiation in later passages, which results in undesirable fibroblastic phenotypes. A promising treatment for cartilage injuries and diseases involves tissue engineering using cells (e.

Hypertension is a leading independent risk factor for the development of cardiovascular disease, the leading cause of death globally. Importantly, the prevalence of hypertension is positively correlated with obesity, with obesity-related hypertension being difficult to treat due to a lack of current guidelines in this population as well as limited efficacy and adverse off-target effects of currently available antihypertensive therapeutics. This highlights the need to better understand the mechanisms linking hypertension with obesity to develop optimal therapeutic approaches.

Interstitial lung diseases (ILDs) are pathologies affecting the pulmonary interstitium and, less frequently, the alveolar and vascular epithelia. Bronchoalveolar lavage (BAL) is commonly used in ILD evaluation since it allows the sampling of the lower respiratory tract. The prognostic value of BAL cell counts in ILD is unknown.

Testing the Isotropic Cauchy Hypothesis.

Entropy (Basel)

December 2024

Department of Electrical and Computer Engineering, American University of Beirut, P.O. Box 11-0236, Beirut 1107 2020, Lebanon.

The isotropic Cauchy distribution is a member of the central α-stable family that plays a role in the set of heavy-tailed distributions similar to that of the Gaussian density among finite second-moment laws. Given a sequence of observations, we are interested in characterizing the performance of Likelihood Ratio Tests, where two hypotheses are plausible for the observed quantities: either isotropic Cauchy or isotropic Gaussian. Under various setups, we show that the probability of error of such detectors is not always exponentially decaying with , with the leading term in the exponent shown to be logarithmic instead, and we determine the constants in that leading term.

Endophthalmitis is an intraocular microbial infection that can lead to permanent blindness, even with prompt anti-microbial therapy. Multi-drug-resistant organisms are on the rise, potentially limiting the efficacy of current empiric antibiotic therapies of intravitreal ceftazidime and vancomycin. Cefiderocol is a recent FDA- and EMA-approved antibiotic for multi-drug-resistant Gram-negative bacteria.

From Spent Black and Green Tea to Potential Health Boosters: Optimization of Polyphenol Extraction and Assessment of Their Antioxidant and Antibacterial Activities.

Antioxidants (Basel)

December 2024

Department of Nutrition and Dietetics, Faculty of Health Sciences, Beirut Arab University, Tarik El Jedidah, Riad El Solh, P.O. Box 115020, Beirut 1107 2809, Lebanon.

Tea, one of the most popular beverages worldwide, generates a substantial amount of spent leaves, often directly discarded although they may still contain valuable compounds. This study aims to optimize the extraction of polyphenols from spent black tea (SBT) and spent green tea (SGT) leaves while also exploring their antioxidant and antibacterial properties. Response surface methodology was utilized to determine the optimal experimental conditions for extracting polyphenols from SBT and SGT.

Introduction: Accessory spleens are a common anatomical variant, consisting of ectopic splenic tissue present in different locations in the peritoneal cavity. Typically asymptomatic, the presence of these tissue grows to be of clinical importance when complicated by infarction, rupture, or torsion.

Presentation Of Case: We report the case of a 36-year-old female that presented to the Emergency Department for diffuse abdominal pain and was found to have a partially ruptured splenule secondary to a venous infarct on abdominal computed tomography scan.

Processed and ultra-processed foods are associated with depression and anxiety symptoms in a cross-sectional sample of urban Lebanese adults.

Nutr Res

December 2024

Faculty of Medicine, Department of Internal Medicine, American University of Beirut Medical Center, Beirut, Lebanon; Faculty of Medicine, Clinical Research Institute, American University of Beirut, Beirut, Lebanon.

While low dietary quality has been linked to poor mental health, evidence on more direct relations of specific dietary quality indicators, namely degrees of food processing, with mental health disorders remains limited. This study aims to investigate the association between food groups' intakes, defined based on their degree of food processing, with depression and anxiety symptoms in a sample of Lebanese adults. We hypothesized that higher intakes of ultra-processed foods (UPF) will be related to higher risk of depression and anxiety while an opposite association will be observed for unprocessed or minimally processed foods (MPF).

Assistant Director-General of the Universal Health Coverage, Life Course Division, World Health Organization Headquarters, Geneva.

The 'next pandemic' has become a common terminology increasingly used in media and academic literature. Emerging pathogens pose a considerable risk to our increasingly globalised communities and there is a need for adequate preparedness for them. However, in Lebanon, like in many countries, the 'next' pathogens, such as the measles pathogen, posing a dire threat to public health are neither emerging nor re-emerging; they are common, endemic and vaccine-preventable.

January 2025

Dartmouth Hitchcock Medical Center, Section of Allergy and Clinical Immunology, Lebanon, NH; Geisel School of Medicine at Dartmouth, Departments of Medicine and Pediatrics. Electronic address:

The art of clinical negotiation is an important, yet underappreciated aspect of medicine. Key components of negotiation include the need to consider principles over personalities, to explore all options before deciding on the best course, to realize if consensus cannot be achieved then compromise may still be possible, to work from evidence to incorporate contextual factors, and to stay evidence based. These principles can be helpful in many settings, including contract negotiation, drug pricing, and research.
