Abstract

Surgical management strategies for glioblastoma (GBM) may differ among neurosurgeons with initial biopsy of suspected tumors and the need for early re-resection of tumors within 30 days of initial surgery. This study was initiated by the American Association of Neurological Surgeons (AANS) and Congress of Neurological Surgeons (CNS) Tumor Section's interest in understanding the rates at which pre- and post-resection procedures, specifically biopsies prior to definitive resection and early re-resections, are performed by U.S. neurosurgeons in the management of GBM. A ten-question survey was distributed to members of the AANS/CNS Tumor Section. The survey response rate among AANS/CNS Tumor Section surgeons was approximately 16%. Results showed that a majority of respondents performed surgery on 11-25 GBM cases annually. Of those cases, most neurosurgeons claimed that biopsies are rarely performed prior to tumor resection, but in the < 10% of cases for which biopsies are done, common reasons are to confirm radiological findings or improve the treatment plan. Likewise, re-resections are rare, but in the < 5 cases most neurosurgeons performed annually, common reasons included incomplete initial resections, referrals for greater rese...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.
