Crohn's disease and ulcerative colitis: morbidity and mortality

Abstract

This study analyzes hospital discharges and deaths from 1971 to 1986 for patients with inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis. The data are based on hospital morbidity and mortality statistics provided to Statistics Canada by the provinces. For Crohn's disease, age-standardized rates per 100,000 population for hospital discharges increased by 148% for males and by 192% for females over the study period. In 1986, the rate for females was 48% higher than the rate for males. For both males and females, age-specific discharge rates were highest in the 20-24 age group. For ulcerative colitis, male age-standardized discharge rates decreased by 17% from 1971 to 1977, and then increased by 41% from 1977 to 1986. For females, the rates decreased by 18% from 1971 to 1976, then remained fairly stable from 1976 to 1986. Male and female discharge rates were similar over the study period. For females, rates were highest in the 20-34 age groups; for males, they were highest in the 65 and older age groups. In 1971, rates for both types of IBD were almost the same, but by the end of the study period the rate per 100,000 population for Crohn's disease was 34 for females and 23 for males, while for...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.
