Introduction: Aflibercept 8 mg administered in extended dosing intervals has shown non-inferior visual gains and comparable safety profile to aflibercept 2 mg in the PULSAR pivotal randomized clinical trial and has the potential to reduce the treatment burden of treating neovascular age-related macular degeneration (nAMD). This study aimed at gathering robust evidence to assess the comparative efficacy, safety, and treatment burden of aflibercept 8 mg against other anti-vascular endothelial growth factor (VEGF) agents as ranibizumab, brolucizumab, faricimab, and bevacizumab in patients with nAMD.

Methods: A systematic literature review (SLR) was conducted, targeting clinical trials of anti-VEGF agents in patients with nAMD.

This study illustrates the utility of a mixed-methods approach in assessing the value of an example novel technology-biosensor-integrated self-reporting arteriovenous grafts (smart AVGs). Currently in preclinical development, the device will detect arteriovenous graft stenosis (surveillance-only use case) and treat stenosis (interventional use case). The approach to value assessment adopted in this study was multifaceted, with one stage informing the next and comprised a stakeholder engagement with clinical experts to explore the device's clinical value, a cost-utility analysis (CUA) from a US Medicare perspective to estimate pricing headroom, and an investment model estimating risk-adjusted net present value analysis (rNPVs) to determine commercial viability.

The urgent need to address both human and environmental health crises has brought attention to the role of food systems in driving climate change, biodiversity loss, and diet-related diseases. This paper explores the intersection of Food is Medicine (FIM) and regenerative agriculture (RA) as an emerging approach with the potential to help address the interconnected challenges of human and ecological health within healthcare and food systems. FIM programs, such as produce prescriptions and medically tailored meals, aim to improve health outcomes by increasing access to nutritious foods and promoting nutrition equity.

While advancements in critical care and burn treatment have improved over the decades, elderly burn victims continue to face high mortality rates. Measurements of frailty among patients have become popular tools for predicting burn outcomes over chronological age. In this report, we provide a case of a non-frail octogenarian burn victim who deteriorated rapidly during treatment, suggesting that frailty alone is not sufficient in predicting outcomes in older burn patients.

Currently, interferon-gamma release assay (IGRA) is costly and not included as latent tuberculosis infection (LTBI) screening test strategy in Thailand's Universal Coverage Scheme (UCS) benefit package. The objective of this study was to assess the cost-utility of LTBI screening strategies among tuberculosis (TB) contacts in Thailand. A hybrid decision tree and Markov model was developed to compare the lifetime costs and health outcomes of tuberculin skin test (TST) and IGRA, in comparison to no screening, based on a societal perspective.

Importance: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Observational studies report that β-blocker use may be associated with reduced risk of COPD exacerbations. However, a recent trial reported that metoprolol did not reduce COPD exacerbations and increased COPD exacerbations requiring hospital admission.

Article Synopsis
  • Patients on long-term cancer treatment often use specific venous access devices, with recent studies suggesting that implantable chest wall ports (PORT) are safer and improve patient satisfaction compared to Hickman (HICK) and peripherally inserted central catheters (PICC), although they are more costly and do not enhance quality-adjusted life years.* -
  • A cost-consequence analysis showed that while PORT had a lower overall complication rate and fewer unplanned removals compared to HICK and PICC, there was no significant difference in chemotherapy interruptions or patient health outcomes, although the total cost for using PORT was lower than HICK and similar to PICC.* -
  • The study suggests that PORT could be a cost-effective option

Uterine leiomyomas cause heavy menstrual bleeding, anemia, and pregnancy loss in millions of women worldwide. Driver mutations in the transcriptional mediator complex subunit 12 (MED12) gene in uterine myometrial cells initiate 70% of leiomyomas that grow in a progesterone-dependent manner. We showed a distinct chromatin occupancy landscape of MED12 in mutant MED12 (mut-MED12) versus WT-MED12 leiomyomas.
