Global Burden of Dry Age-Related Macular Degeneration: A Targeted Literature Review

Clin Ther. 2021 Sep 18:S0149-2918(21)00310-6. doi: 10.1016/j.clinthera.2021.08.011. Online ahead of print.ABSTRACTPURPOSE: Age-related macular degeneration (AMD) is a leading cause of blindness, particularly in higher-income countries. Although dry AMD accounts for 85% to 90% of AMD cases, a comprehensive understanding of the global dry AMD burden is needed.METHODS: A targeted literature review was conducted in PubMed, MEDLINE, Embase, and the Cochrane Database of Systematic Reviews (1995-2019) to identify data on the epidemiology, management, and humanistic and economic burden of dry AMD in adults. A landscape analysis of patient-reported outcome (PRO) instruments in AMD was also conducted via searches in PubMed (1995-2019), ClinicalTrials.gov, PROQOLID, PROLABELS, and health technology assessment reports (2008-2018).FINDINGS: Thirty-seven of 4205 identified publications were included in the review. Dry AMD prevalence was 0.44% globally, varied across ethnic groups, and increased with age. Patients with dry AMD had higher risks of all-cause mortality (hazard ratio [HR] = 1.46; 95% CI, 0.99-2.16) and tobacco-related (HR = 2.86; 95% CI, 1.15-7.09) or cancer deaths (HR = 3.37; 95% CI, 1.56-7.29; P = 0.002) than those without dry AMD. Smoking, increasing age or cholesterol levels, and obesity are key risk factors for developing dry AMD. No treatment guidelines were identified for dry AMD specifically; management focuses on risk factor reduction and use of dietary supplements. In...

ConclusionAcid hydrolysis enhances the skin sensitizing capacity of gluten and drives IgE reactivity to more gluten proteins. This property of acid hydrolyzed gluten may be related to the degree of product deamidation, and could be a strong trigger of wheat allergy in susceptible individuals.

This article expresses sentiments regarding medical technology and human longevity that we'd all like to see more of in the mainstream media. At some point, it will come to be seen by the average person as basically sensible to work towards minimizing the tide of suffering and death caused aging and age-related disease. It has been, in hindsight, a strange thing to live in a world in which most people were reflexively opposed to that goal. Death and aging constitute a mystery. Some of us die more quickly. We often ask about it as children, deny it in youth, and reluctantly come to accept it as adults. Aging is uni...

The objective of this study is to quantify the overall and cancer type-specific risks of subsequent primary cancers (SPCs) among adult-onset cancer survivors by first primary cancer (FPC) types and sex. Among 1,537,101 survivors (mean age, 60.4 years; 48.8% women), 156,442 SPC cases and 88,818 SPC deaths occurred during 11,197,890 person-years of follow-up (mean, 7.3 years). Among men, the overall risk of developing any SPCs was statistically significantly higher for 18 of the 30 FPC types, and risk of dying from any SPCs was statistically significantly higher for 27 of 30 FPC types as compared with risks in the general po...

In this study, we found that cofilin competes with tau for direct microtubule binding in vitro, in cells, and in vivo, which inhibits tau-induced microtubule assembly. Genetic reduction of cofilin mitigates tauopathy and synaptic defects in Tau-P301S mice and movement deficits in tau transgenic C. elegans. The pathogenic effects of cofilin are selectively mediated by activated cofilin, as active but not inactive cofilin selectively interacts with tubulin, destabilizes microtubules, and promotes tauopathy. These results therefore indicate that activated cofilin plays an essential intermediary role in neurotoxic signaling th...

In this study, we found that TXNIP deficiency induces accelerated senescent phenotypes of mouse embryonic fibroblast (MEF) cells under high glucose condition and that the induction of cellular ROS or AKT activation is critical for cellular senescence. Our results also revealed that TXNIP inhibits AKT activity by a direct interaction, which is upregulated by high glucose and H2O2 treatment. In addition, TXNIP knockout mice exhibited an increase in glucose uptake and aging-associated phenotypes including a decrease in energy metabolism and induction of cellular senescence and aging-associated gene expression. We propose that...

This report captures the state of the research community in a nutshell: progress in the sense that ever more scientists are willing to make the treatment of aging the explicit goal of their research, but, unfortunately, there is still a long way to go in improving the nature of that research. It is still near entirely made up of projects that cannot possibly produce a robust and large impact on human life span. The only course of action likely to extend life by decades in the near future is implementation of the SENS vision for rejuvenation therapies - to repair the molecular damage that causes aging. Everything else on th...
