Several interventions have recently emerged that were proposed to reverse rather than just attenuate aging, but the criteria for what it takes to achieve rejuvenation remain controversial. Distinguishing potential rejuvenation therapies from other longevity interventions, such as those that slow down aging, is challenging, and these anti-aging strategies are often referred to interchangeably. We suggest that the prerequisite for a rejuvenation intervention is a robust, sustained, and systemic reduction in biological age, which can be assessed by biomarkers of aging, such as epigenetic clocks. We discuss known and putative rejuvenation interventions and comparatively analyze them to explore underlying mechanisms.

Inflammation and Occlusive Retinal Vasculitis Post Faricimab.
JAMA Ophthalmol
January 2025
Truhlsen Eye Center, Department of Ophthalmology and Visual Sciences, University of Nebraska Medical Center, Omaha.
Importance: Randomized clinical trials have shown the safety and efficacy of faricimab as a novel vascular endothelial growth factor and angiopoietin-2 inhibitor in the treatment of neovascular age-related macular degeneration (nAMD) and macular edema of various etiologies. However, more rare adverse events may not be considered in clinical trials.
Objective: To describe 3 eyes that developed irreversible vision loss following initial mild intraocular inflammation (IOI) to faricimab.

Importance: The degree that in-home cannabis smoking can be detected in the urine of resident children is unclear.
Objective: Test association of in-home cannabis smoking with urinary cannabinoids in children living at home.

Painful diabetic neuropathy is associated with accelerated epigenetic aging.
Geroscience

Department of Medical and Surgical Sciences (DIMEC), University of Bologna, Bologna, Italy.
About one out of two diabetic patients develop diabetic neuropathy (DN), of these 20% experience neuropathic pain (NP) leading to individual, social, and health-economic burden. Risk factors for NP are largely unknown; however, premature aging was recently associated with several chronic pain disorders. DNA methylation-based biological age (DNAm) is associated with disease risk, morbidity, and mortality in different clinical settings.

PGT-A, what's it for? Considering the increase in fetal aneuploidies with a woman's age and the high number of miscarriages associated with fetal karyotype anomalies, the concept of selecting IVF embryos based on their karyotype in order to transfer only euploid embryos and eliminate aneuploid ones was proposed. Preimplantation genetic testing for aneuploidy (PGT-A) was then established, nearly 30 years ago, with the expectation that the transfer of euploid embryos would lead to a significant improvement in medically assisted reproduction (MAR) outcomes. PGT-A, what's wrong? Despite the practice and widespread use, PGT-A has not consistently proven its effectiveness.

Purpose: This large-scale retrospective study aimed to examine the long-term effect of antiplatelet and anticoagulant medications intake on dental implant treatment outcome.
Materials And Methods: This study retrospectively examined data from patients who underwent dental implant procedures at several university dental clinics within the BigMouth network between 2011 and 2022. Patients' characteristics including age, gender, ethnicity, race, tobacco use, systemic medical conditions and intake of antiplatelets and anticoagulants were analyzed.
