Abstract

In this multicentre trial tramadol and buprenorphine were compared for the treatment of neoplastic pain no longer responsive to non-steroidal antiinflammatory drugs. A total of 131 adults (86 M, 45F) were treated with tramadol (one 100-mg slow-release tablet every 8-12 h), or buprenorphine (one sublingual 0.2-mg tablet every 6-8 h). The trial was to continue for up to six months. Most patients started treatment with 2-3 tablets/day in both groups, and the mean treatment period was 58 days for tramadol and 51 for buprenorphine. Almost all dose changes needed were made in the first fortnight in both treatment groups, and the largest number of patients dropped out because of inadequate pain relief or progression of the underlying disease. The results achieved in the first two weeks persisted throughout the rest of the trial, and the investigator's assessments on each patient's clinical chart corresponded closely with those that patients made in their own daily diaries. In the four hours after the first dose both drugs virtually halved the severity of pain (measured using a visual analogue scale), and this relief lasted throughout treatment. By the end of the first week the proportion of patients with strong/unbearable pain in the ...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.
