Delirium is one of the most prevalent complications in intensive care unit (ICU) patients, which is related to worse clinical outcomes including a longer ICU stay, longer duration of mechanical ventilation, higher mortality rates and increased risk of cognitive impairment. Observational studies have suggested that statins might have a positive effect on delirium status of hospitalized patients. To date, there has been no trial assessing the effect of atorvastatin on delirium status in critically ill patients. Thus, the aim of the current study was to determine the efficacy of atorvastatin on delirium status of patients in the ICU. ⋯ Administration of atorvastatin had a significant positive effect on delirium status in patients admitted to the ICU.

The aim of the study was to assess the effects of chronic inflammation on incretin levels, inflammatory markers, and enteric neuronal function measured in isolated preparations of smooth muscle of rat. ⋯ We can conclude that chronic inflammation leads to an increase of incretin levels and to a decrease of functional response of colon intestinal smooth muscle after electrical stimulation.

A variety of inflammatory mediators are produced by the degenerative human intervertebral disc (IVD) tissues spontaneously, suggesting their role in the development of intervertebral disc degeneration (IDD). Our present study was designed to investigate the regulatory effect of microRNA-16 (miR-16) on the lipopolysaccharide (LPS)-induced inflammatory response in nucleus pulposus (NP) cells of the IVD. ⋯ Our study suggested that, in NP cells of the IVD, miR-16 could exert inhibitory effects on the LPS-induced inflammatory response through NF-κB and MAPK pathways by directly mediating TAB3. In this way, miR-16 would play a protective role against LPS-induced IDD and inflammation. Therefore, miR-16 may be a novel therapeutic target for the inhibit of the ECM in the IVD.

Probiotics are defined as live microorganisms that have a beneficial effect on health by exhibiting quantitative and qualitative effects on intestinal microflora and/or modification of the immune system. A strain is considered probiotic if it demonstrates a series of clinically proven health benefits. ⋯ The incorrect or inefficient antioxidant mechanisms results in oxidative stress and may occur in the course of many diseases such as diabetes, atherosclerosis, inflammatory bowel disease or damage to the heart, brain or transplanted organs. Correct functioning of antioxidant mechanisms seems to be crucial for the proper functioning of our body; therefore, probiotics should be carefully investigated for potential antioxidant properties.

Hearing loss is one of the most common sensory disorders. Recent findings have shown that the apoptotic program and autophagy are related to hearing loss. The aim of the study was to explore the effects of noise and cisplatin exposure on apoptosis and autophagy in the hair cells of the cochleae. ⋯ Our findings demonstrated for the first time that noise and cisplatin exposure promoted apoptosis and autophagy in the hair cells of the cochleae. This study provides new insights into the mechanisms of noise- or cisplatin-induced hearing loss.
