Abstract

Insights

Occupational asbestos exposure is a significant cause of retroperitoneal fibrosis (RPF). This finding suggests RPF should be recognized as an occupational disease in exposed individuals.

Area of Science:

  • Environmental Health
  • Occupational Medicine
  • Fibrotic Diseases

Background:

  • Retroperitoneal fibrosis (RPF) is a rare condition of unknown cause, characterized by a fibrous mass around the aorta and ureters.
  • Asbestos is known to cause pulmonary and pleural fibrosis, prompting investigation into its role in RPF.

Purpose of the Study:

  • To investigate the potential link between asbestos exposure and the development of retroperitoneal fibrosis (RPF).
  • To determine if occupational asbestos exposure is a causal factor in RPF.

Main Methods:

  • A case-control study involving 43 RPF patients and 179 matched population-based controls in Finland (1990-2001).
  • Asbestos exposure and medical history were assessed via postal questionnaires and personal interviews.

Main Results:

  • RPF showed a strong association with asbestos exposure, with odds ratios increasing with cumulative exposure.
  • Significant risk factors included asbestos exposure (OR 5.54-8.84), ergot derivative use (OR 9.92), abdominal aortic aneurysm (OR 6.73), and heavy smoking (OR 4.73).
  • Attributable fractions for asbestos exposure were high, reaching 82-89%.

Conclusions:

  • Occupational asbestos exposure is identified as a key causal factor for retroperitoneal fibrosis.
  • RPF in individuals with work-related asbestos exposure should be classified as an occupational disease.

Types of Step-Growth Polymers: Polyesters

The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...
Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

PPE Use in Healthcare Settings II: Doffing

The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.
Fibril-associated Collagen01:11

Fibril-associated Collagen

Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...
Fibrous Proteins00:55

Fibrous Proteins

Fibrous proteins are either long and narrow proteins or assemble to form long and thin structures. They contain repetitive units and usually consist of either alpha helices or beta sheets and, in rare cases, a mix of both. The amino acids in the primary structure often consist of repeating amino acid sequences. The role of fibrous proteins is primarily structural. Many are located in the extracellular matrix and are present in connective tissues to impart strength and joint mobility. They are...
Fiber Reinforced Concrete01:22

Fiber Reinforced Concrete

Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...
