Canadian Association of Radiologists Statement on Environmental Sustainability in Medical Imaging.

Immediate and strategic action is needed to improve environmental sustainability and reduce the detrimental effects of climate change. Climate change is already adversely affecting the health of Canadians related to worsening air pollution and wildfire smoke, increasing frequency and intensity of extreme weather events, and expansion of vector-borne and infectious illnesses. On one hand, radiology contributes to the climate crisis by generating greenhouse gas emissions and waste during the production, manufacture, transportation, and use of medical imaging equipment and supplies.

Perfluorooctanoic Acid (PFOA) Exposure and Abnormal Alanine Aminotransferase: Using Clinical Consensus Cutoffs Compared to Statistical Cutoffs for Abnormal Values.

Background: Per- and polyfluoroalkyl substances (PFASs) including perfluorooctanoic acid (PFOA) are ubiquitous environmental contaminants. Prior analysis in the large "C8 Health Project" population defined abnormal alanine aminotransferase (ALT) with statistically derived cutoffs (>45 IU/L in men, >34 IU/L in women).

Objective: To explore the degree to which PFOA was associated with modern, clinically predictive ALT biomarker cutoffs in obese and nonobese participants, excluding those with diagnosed liver disease.

Investigating the mechanism of Ni-mediated trifluoromethylthiolation of aryl halides using AgSCF.

The mechanism of the Ni-catalysed trifluoromethylthiolation of aryl chlorides using AgSCF is studied herein. A variety of IPr Ni complexes were synthesized oxidative addition of Ni to 2-(2-chloro)phenylpyridines. Their reactivity with AgSCF was tested by performing stoichiometric experiments, cyclic voltammetry, and NMR spectroscopic studies.

Finding the right fit: What contributes to the successful use of speech generating devices?

Many conditions can lead to a result in communication difficulties in both children and adults. One intervention utilized by rehabilitation professionals to overcome the problem is the use of speech-generating devices. Although the majority of users benefit from these tools, it is reported that roughly one third eventually abandon them.

Leptospirosis: A Rare Cause of Hyperbilirubinemia and Acute Kidney Injury in a Non-endemic Area.

Leptospirosis is a zoonosis with clinical manifestations caused by a pathogenic bacterium of the genus . A high index of suspicion is required to make the diagnosis. The unusual constellation of symptoms makes the diagnosis of leptospirosis challenging and requires a comprehensive approach while treating the patient.
