Abstract

It has been suggested that the risk of stomach cancer is increased when there is a history of gastric ulcer, but decreased in those with a history of duodenal ulcer. To provide further information on the issue, data from a case-control study of gastric cancer conducted in greater Milan, northern Italy, between 1985 and 1993, were examined. There were 746 cases of gastric cancer below the age of 75 and 2,053 controls admitted to hospital for acute, non-neoplastic, non-hormone-related diseases. A total of 76 (10.2%) cases and 84 (4.1%) controls reported a history of gastric ulcer, corresponding to a multivariate odds ratio (OR) of 2.6 (95% confidence interval, CI = 1.8-3.6). Fifty nine cases (7.9%) and 111 (5.4%) controls reported a history of duodenal ulcer, corresponding to an OR of 1.3 (95% CI = 0.9-1.8). The OR of gastric cancer was significantly above unity for the first five years after diagnosis of gastric ulcer (OR = 7.4, 95% CI 3.7-14.8), and declined thereafter. No consistent pattern of risks was observed after duodenal ulcer. The present data therefore confirm that the risk of gastric cancer is increased after gastric ulcer. They do not support, however, a reduced risk after duodenal ulcer. This may be due to variable ...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.
