The authors justify importance of biologic monitoring to increase quality of hygienic control over and diagnosis of occupational disease. The article covers data on international terminology for exposure tests parameters. Although difficult in elaboration, the exposure tests are highly informative and necessary to be put into practice.

Humans are constantly exposed to micro- and nanosized plastics (MNPs); however, there is still limited understanding of their fate within the body, partially due to limitations with current analytical techniques. The current study assessed the appropriateness of pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) analysis for the quantification of a range of polymers in human blood. An extraction protocol that reduced matrix interferences (false positives) of polyethylene (PE) and polyvinyl chloride (PVC) was developed and validated.

Chronic headaches and pain are prevalent in those who are exposure to blast events, yet there is a gap in fundamental data that identifies the pathological mechanism for the chronification of pain. Blast-related post-traumatic headaches (PTH) are understudied and chronic pain behaviors in preclinical models can be vital to help elucidate PTH mechanisms. The descending pain modulatory system controls pain perception and involves specific brain regions such as the cortex, thalamus, pons, and medulla.

The pandemic of coronavirus disease 2019 (COVID-19) had a major impact on the health of people worldwide, including the pediatric inflammatory bowel disease (PIBD) patients. As no study has investigated the susceptibility and disease course of COVID-19 in PIBD patients after the end of zero-COVID policy in China, we conducted a retrospective cross-sectional study in our center. A cross-sectional survey enrolling PIBD patients has been completed by online survey, phone, and face-to-face assessment.

Polygenic scores for educational attainment and related variables, such as IQ and "mathematical ability" are now readily available via direct-to-consumer genetic testing companies. Some researchers are even proposing the use of genetic tests in educational settings via "precision education," in which individualized student education plans would be tailored to polygenic scores. The potential psychosocial impacts of polygenic scores for traits and outcomes relevant to education, however, have not been assessed.
