The Clinicians' Guide to Large Language Models: A General Perspective With a Focus on Hallucinations.

Large language models (LLMs) are artificial intelligence tools that have the prospect of profoundly changing how we practice all aspects of medicine. Considering the incredible potential of LLMs in medicine and the interest of many health care stakeholders for implementation into routine practice, it is therefore essential that clinicians be aware of the basic risks associated with the use of these models. Namely, a significant risk associated with the use of LLMs is their potential to create hallucinations.

Spatial Scale Matters: Hydrolysis of Aryl Methyl Ethers over Zeolites.

The local environment of the active site, such as the confinement of hydronium ions within zeolite pores, significantly influences catalytic turnover, similar to enzyme functionality. This study explores these effects in the hydrolysis of guaiacols─lignin-derived compounds─over zeolites in water. In addition to the interesting catechol products, this reaction is advantageous for study due to its bimolecular hydrolysis pathway, which involves a single energy barrier and no intermediates, simplifying kinetic studies and result interpretation.

Risk characterization of organic micropollutants in public wastewater treatment plant effluents in Flanders, Belgium.

This study investigates the ecological risks posed by organic micropollutants (OMPs) in wastewater treatment plant (WWTP) effluents in Flanders, Belgium based on single-compound risk characterization. Utilizing a five-year monitoring dataset from the Flemish Environment Agency (VMM) and employing seven ecological threshold values (ETV) types, this research characterizes the risk of 207 OMPs, including pharmaceuticals, pesticides, industrial chemicals, and other pollutants. Several OMPs persist in effluents at concentrations that pose significant ecological risks after secondary and tertiary treatment processes in the region of Flanders (Belgium).

Pulmonary vascular complications of cirrhosis: hepatopulmonary syndrome and portopulmonary hypertension.

Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (POPH) are two distinct pulmonary vascular complications seen in patients with liver disease and/or portal hypertension. HPS is characterized by disturbed gas exchange and hypoxemia because of intrapulmonary vascular dilatations. POPH is defined by pulmonary arterial hypertension, which might lead to right heart failure.

Biodiversity within phytoplankton-associated microbiomes regulates host physiology, host community ecology, and nutrient cycling.

Unlabelled: Biological diversity is declining across the tree of life, including among prokaryotes. With the increasing awareness of host-associated microbes as potential regulators of eukaryotic host physiology, behavior, and ecology, it is important to understand the implications of declining diversity within host microbiomes on host fitness, ecology, and ecosystem function. We used phytoplankton and their associated environmental microbiomes as model systems to test the independent and interactive effects of declining microbiome diversity with and without other stressors often caused by human activity-elevated temperature and altered nutrient availability.
