Genome-wide association study meta-analysis provides insights into the etiology of heart failure and its subtypes.

Heart failure (HF) is a major contributor to global morbidity and mortality. While distinct clinical subtypes, defined by etiology and left ventricular ejection fraction, are well recognized, their genetic determinants remain inadequately understood. In this study, we report a genome-wide association study of HF and its subtypes in a sample of 1.

Prevalence and demographics of 331 rare diseases and associated COVID-19-related mortality among 58 million individuals: a nationwide retrospective observational study.

Background: The Global Burden of Disease Study has provided key evidence to inform clinicians, researchers, and policy makers across common diseases, but no similar effort with a single-study design exists for hundreds of rare diseases. Consequently, for many rare conditions there is little population-level evidence, including prevalence and clinical vulnerability, resulting in an absence of evidence-based care that was prominent during the COVID-19 pandemic. We aimed to inform rare disease care by providing key descriptors from national data and explore the impact of rare diseases during the COVID-19 pandemic.

An International Survey on the Use of a Polyrevitalizing Solution With or Without Other Aesthetic Procedures in the Daily Practice of Aesthetic Physicians.

Objective: NCTF135HA, a versatile polyrevitalizing solution, is a potent agent for enhancing skin quality, radiance, moisture, vitality, and diminishing fine wrinkles caused by aging factors. Data demonstrate a divergence in its application from skin quality enhancement to treatment of vitiligo lesions. To know more precisely about the protocol of use among providers, alone or in combination with other procedures, we performed an international survey.

Evaluation of the Performance and Safety of a New Micro-Needle Technology in Comparison With the Classic Needle on the Antiaging Effects of a Biorevitalizing Solution: A Randomized Split Face/Neck Study.

Background: Skin biorevitalization involves multiple intradermal injections to enhance skin quality, but precise dermal targeting can be challenging due to variations in skin thickness smaller, less painful needles with fewer skin reactions are attractive options.

Aims: This study evaluates a new Micro-Needle device's performance and safety in comparison with the classic needle used in skin biorevitalization.

Patients/methods: Subjects with facial and neck skin aging were enrolled.

A hyaluronic acid-based micro-filler improves superficial wrinkles and skin quality: a randomized prospective controlled multicenter study.

Background: NCTF®135HA is a bio-revitalizing solution containing hyaluronic acid designed to compensate for skin dehydration, fatigue, and fine wrinkles associated with endogenous and environmental aging.

Methods: We conducted a randomized, active-controlled study to evaluate the efficacy and tolerability of NCTF®135HA injections on the face (crow's feet), neck, and décolleté regions. Subjects were randomly assigned (3:1) to receive three NCTF®135HA treatment sessions plus twice-daily anti-aging moisturizer cream or cream alone (control).

Lung Cancer and Risk Factors in Lebanon: Epidemiology, Temporal Trends, and Comparison to Countries From Different Regions in the World.

Background: Lung cancer (Lca) is the leading cause of cancer morbidity and mortality worldwide. This study examines the Lca incidence and trends in Lebanon and compares them to regional and global ones. It also discusses Lca risk factors in Lebanon.

University students' intentions to seek psychological counseling, attitudes toward seeking psychological help, and stigma.

Background: Mental health problems are prevalent among university students worldwide. Studies have shown that most students do not disclose and do not get the psychological help and support they need.

Objectives: This survey aims to investigate the intentions to seek psychological counseling (ISC) among university students, their attitudes toward seeking professional psychological help (ATSPPH), and the predictors of those intentions and attitudes including stigma.

The Effects of a Non-crossed-linked Hyaluronic Acid Gel on the Aging Signs of the Face versus Normal Saline: A Randomized, Double-blind, Placebo-controlled, Split-faced Study.

Background: Skin bio-revitalization improves skin quality globally; it permits the rejuvenation of the skin by increasing hydration and by reconstructing an optimal physiological environment for the skin cells together with a micro-filling effect.

Objective: To assess the comparative efficacy of a non-cross-linked hyaluronic acid (NCHA) preparation (M-HA®10, FILLMED Laboratories, France) on fine lines reduction and on skin hydration, radiance and mechanical properties, after three sessions of multiple intradermal injections, active versus placebo, on the face of subjects presenting aging signs.

Methods: Thirty healthy subjects received filler injections on one side and a control solution (saline) on the contralateral side of the face.

Protective effectiveness of previous SARS-CoV-2 infection and hybrid immunity against the omicron variant and severe disease: a systematic review and meta-regression.

Background: The global surge in the omicron (B.1.1.

Prescribing antibiotics in adults with respiratory tract infections in Lebanon.

Introduction: Antibiotic resistance is a global concern that has significant health and economic burden. The inappropriate use of antibiotics is a major cause of antibiotic resistance; this includes both unnecessary and incorrect prescriptions. Most antibiotics are prescribed in primary care, mainly for respiratory tract infections.

A Pilot Intervention to Promote Positive Parenting in Refugees from Syria in Lebanon and Jordan.

Background: Early childhood development (ECD) is a crucial milestone that shapes a child's health, wellbeing, education, and personality. Several factors come into play, and each requires the nurturing care of caregivers. Although the importance of ECD is well understood, the implementation of ECD programs is scarce, especially in poor and vulnerable communities.

Click-chemistry approach to study mycoloylated proteins: Evidence for PorB and PorC porins mycoloylation in Corynebacterium glutamicum.

Protein mycoloylation is a recently identified, new form of protein acylation. This post-translational modification consists in the covalent attachment of mycolic acids residues to serine. Mycolic acids are long chain, α-branched, β-hydroxylated fatty acids that are exclusively found in the cell envelope of Corynebacteriales, a bacterial order that includes important genera such as Mycobacterium, Nocardia or Corynebacterium.

Mycoloyltransferases: A large and major family of enzymes shaping the cell envelope of Corynebacteriales.

Mycobacterium and Corynebacterium are important genera of the Corynebacteriales order, the members of which are characterized by an atypical diderm cell envelope. Indeed the cytoplasmic membrane of these bacteria is surrounded by a thick mycolic acid-arabinogalactan-peptidoglycan (mAGP) covalent polymer. The mycolic acid-containing part of this complex associates with other lipids (mainly trehalose monomycolate (TMM) and trehalose dimycolate (TDM)) to form an outer membrane.
