Objective: Determine current analytical methods and number of cell-free (cf) DNA prenatal screening tests performed for common trisomies.
Methods: The College of American Pathologists 2022-B Noninvasive Prenatal Testing exercise was distributed in December 2022 to 93 participants in 22 countries. Supplemental questions included the number of tests performed in a recent month and the proportion of samples originating outside the United States (US).
Therapeutic plasma exchange is known to be an extracorporeal treatment procedure with few adverse effects. Anemia in chronically exchanged patients is not a well-recognized adverse effect. Our aim is to find if adult patients develop anemia while undergoing prolonged TPE treatments and to determine the time of onset of anemia.

Static hyperinflation is an independent risk factor for all-cause mortality in COPD and for COPD exacerbation. In a multicentre, cross-sectional study (BPROFETIO), we sought to analyse the relationship between static hyperinflation and occupational exposure in patients with COPD with or without occupational exposure.

Article Synopsis
- Occupational lung cancer cases are often under-reported and under-compensated, prompting a study to improve detection and compensation through systematic screening of occupational exposures.
- A self-administered questionnaire was used to gather job history and exposure data from lung cancer patients, with physician assessments leading to specialized consultations for those with potential occupational links.
- The study found that out of 1251 patients surveyed, a significant portion attended consultations, revealing that many had been exposed to occupational lung carcinogens and subsequently received medical certificates and compensation, highlighting the effectiveness of this screening approach.
Article Synopsis
- * In 2020, 56 laboratories reported screening over 1.1 million pregnancies, with a notable drop in testing numbers and a decrease in the number of labs offering these tests compared to eight years earlier.
- * The significant decline in traditional serum screening (up to 72%) was attributed to the rise of cell-free DNA testing, which saw a substantial increase in usage during the same period.
