Comparison of trabectome and microhook surgical outcomes.

Several methods can be applied for a trabeculotomy, including the uses of thread, a blade, cauterization, and a hook. We compared the outcomes of trabectome surgery and microhook surgery. We analyzed the cases of 133 eyes that underwent trabectome (72 eyes) or microhook (61 eyes) surgery and were followed for > 1 year. We defined failure as a < 20% reduction in the postoperative intraocular pressure (IOP) value or requiring additional glaucoma surgery. We used three surgical success definitions: ≤ 21, ≤ 18, and ≤ 15 mmHg IOP reduction. A Kaplan-Meier survival analysis was performed for the surgical outcomes. We compared the trabectome and microhook groups' postoperative IOP values, number of glaucoma medications, and postoperative complications. At 1 year postsurgery, the trabectome surgeries decreased the IOP significantly from 24.6 ± 7.3 to 13.3 ± 3.7 mmHg, and the microhook surgeries significantly decreased the IOP from 24.1 ± 9.2 to 12.5 ± 3.9 mmHg. The two groups' 1-year postoperative IOP values were not significantly different (p = 0.310). The surgical outcomes of the trabectome surgeries were significantly better than those of the microhook surgeries (≤ 21 mmHg: p = 0.0049, ≤ 18 mmHg: p = 0.0029, and ≤ 15 mmHg: p = 0.039...Continue Reading

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.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh Isoimmunization

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.

Enzyme Evolution

This feed focuses on molecular models of enzyme evolution and new approaches (such as adaptive laboratory evolution) to metabolic engineering of microorganisms. Here is the latest research.

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.

Pharmacology of Proteinopathies

This feed focuses on the pharmacology of proteinopathies - diseases in which proteins abnormally aggregate (i.e. Alzheimer’s, Parkinson’s, etc.). Discover the latest research in this field with this feed.

Alignment-free Sequence Analysis Tools

Alignment-free sequence analyses have been applied to problems ranging from whole-genome phylogeny to the classification of protein families, identification of horizontally transferred genes, and detection of recombined sequences. Here is the latest research.
