Several studies have indicated that lipoproteins might contribute to the pathogenesis of age-related macular degeneration (AMD). In this population-based retrospective cohort study, patients with hyperlipidemia were divided into two groups (study groups I and II) based on whether or not they were receiving antihyperlipidemic agents. The comparison group included patients without hyperlipidemia who were randomly selected and matched with study group II patients. A Cox proportional hazard model was used to evaluate the risk of AMD among the groups. Patients with hyperlipidemia receiving antihyperlipidemic agents (study group I, n = 15,482) had a significantly increased AMD risk (adjusted hazard ratio (HR) = 1.23, 95% confidence interval (CI) = 1.04-1.45) compared to those not receiving antihyperlipidemic agents (study group II, n = 15,482). However, with an increase in cumulative exposure, a reduced risk of AMD was observed in patients using a defined daily dose of more than 721, with an adjusted HR of 0.34 (95% CI = 0.22-0.53, < 0.001). Additionally, the adjusted HR of AMD for study group II was 1.40 (95% CI = 1.20-1.63, < 0.001) relative to the comparison group (n = 61,928). In conclusion, the study results indicated that patients with hyperlipidemia have a higher AMD risk than patients without hyperlipidemia. Furthermore, patients with hyperlipidemia who received antihyperlipidemic agents had a significantly increased AMD risk. However, a dose-dependent reduction in the risk of AMD was observed in patients with hyperlipidemia using statins or/and fibrates.

Introduction: Despite its low prevalence, premature myocardial infarction (MI) bears serious social consequences and shares different pathophysiology.
Objectives: The aim of the study was to evaluate young MI patients in terms of clinical characteristics and long-term outcomes.
Patients And Methods: This study is an observational research covering 221 patients <45 years old [16.
Background: Meta-analyses have suggested that the risk of cardiovascular disease events is significantly higher after a chronic obstructive pulmonary disease (COPD) exacerbation, but the populations at highest risk have not been well characterized to date.
Methods And Results: The authors analyzed the risk of atherosclerotic cardiovascular disease (ASCVD) hospitalizations after COPD hospitalization compared with before COPD hospitalization and patient factors associated with ASCVD hospitalizations after COPD hospitalization among 2 high-risk patient cohorts. The primary outcome was risk of an ASCVD hospitalization composite outcome (myocardial infarction, coronary artery bypass graft, percutaneous coronary intervention, stroke, transient ischemic accident) after COPD hospitalization relative to before COPD hospitalization.

A patient with a history of Asian flu, mumps meningo-encephalitis, and skull-base fracture and severe porencephaly who was able to walk without assistance, has not been reported. The patient is a 65 year-old male with a history of Asian flu at 6 months of age, Mumps meningoencephalitis at 6 years of age, structural epilepsy since 15 years of age, traumatic brain injury with skull-base fracture at 51 years of age, arterial hypertension, diabetes, hyperlipidemia, previous alcoholism, and polyneuropathy. He presented with only mild right-sided spastic hemiparesis, dysarthria, decreased tendon reflexes in the lower limbs, spastic-ataxic gait, but he was able to walk unassisted.

Background: With the aging of the population, the deterioration of visual and auditory functions amongst the elderly has attracted much attention. Age-related hearing loss (ARHL) and age-related macular degeneration (AMD) are common eye and ear diseases that seriously affect the quality of life of elderly population.
Methods: This study utilised a whole cohort sampling method, with a total of 713 participants aged 50 years and older in the community from June 2022 to October 2023, resulting in the inclusion of 620 participants.

Unitat de Medicina Vascular I Metabolismo, Hospital Universitario Sant Joan, Universitat Rovira I Virgili, IISPV, CIBERDEM, Reus, Spain.
Purpose Of The Review: A significant number of patients fail to achieve target LDL cholesterol (LDL-C) levels. This review aims to explore why inclisiran, a novel class of LLT, should be considered a valuable addition to the current treatment options.
Recent Findings: Inclisiran is a small interfering RNA (siRNA) that targets PCSK9 synthesis specifically in the hepatocytes.
