Abstract

Pedicle screws (PS) offer great benefits in posterior lumbar interbody fusion (PLIF), but several drawbacks of PS, including the risk of superior facet joint violation and muscle injury, have also pointed out. Recently, cortical screws (CS) were invented, which can be placed without the drawbacks associated with PS. However, whether CS in PLIF can provide similar or greater clinical and radiologic outcomes compared to those of PS has not been fully evaluated in clinical research studies. To evaluate whether the CS provides similar results to the PS in PLIF, in terms of fusion rate, clinical and surgical outcomes, and complications. This is a prospective, randomized, noninferiority trial. Seventy-nine eligible patients were randomly assigned to either Group A (39 patients), for which PS was used, or Group B (40 patients), for which CS was used. The primary study end point was to measure fusion rate using dynamic radiographs and computed tomography scans. Secondary end points included intensity of low back pain and pain radiating to the leg using visual analog scales, and also, functional status using the Oswestry Disability Index, surgical morbidity, and additional outcomes such as pedicle fracture and mechanical failure.

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.
