Abstract

To evaluate the association of socioeconomic status (SES) with severity of glaucoma and assess the impacts of both SES and disease-severity factors on the costs of glaucoma medications among different glaucoma subtypes in West Bengal, India. This cross-sectional study (2014-16) followed the treatment of 304 primary glaucoma patients for at least 18 months. The visual field based glaucoma staging was followed for stages 0-3; patients with field of vision <10° were categorized as stage 4 (end stage). We checked only the mean cost of glaucoma medications per patient and not "direct costs." The individuals' monthly incomes were classified into: low, moderate, and higher SES. Urban residence (odds ratio [OR] 0.6, P < 0.009), higher SES (OR 0.3, P < 0.001), and higher awareness (nearly 50%, P < 0.007) significantly lowered the odds of having end-stage glaucoma. Sixty-nine percent primary angle-closure glaucoma (PACG) and 79% juvenile open-angle glaucoma (JOAG) belonged to low SES, forming the bulk of end-stage glaucoma. Overall medical cost from stage 0 to advanced stage in all subtypes rises except in primary open-angle glaucoma (POAG). Only 28% eyes from low SES were treated with branded drugs in early disease and that too declined...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
