Abstract

Hearing loss has been described in patients with chronic renal failure on regular dialysis treatment (RDT) with very different frequency, ranging from 20 to 75%; RDT does not seem to worsen hearing function for at least the first 5 years of treatment; no studies are available on patients on RDT for more than 10 years. We performed an audiometric evaluation in 91 patients on RDT for various periods: group I (34 patients), < 5 years; group II (32 patients), 5-10 years; group III (25 patients), > 10 years; patients with histories of chronic otitis, ototoxic drug treatment, and chronic auditory trauma were excluded; the possible correlations with some biochemical parameters (urea, creatinine, PTH) were also looked for. Hearing loss was present in 77% of patients and 69.2% of ears; the percentage of patients with hypoacusia was higher in group III (84%) than in group I (76.3%) and II (71.7%), but the differences were not statistically significant. Hypoacusia was cochlear neurosensory in 61.5%, conductive in 6.5%, and mixed in 9.0% of patients; the percentage of patients with cochlear neurosensory hypoacousia was similar in the three groups (I, 61.7%; II, 59.3%; III, 64%). Hearing loss was of slight to moderate degree and not differe...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.
