OBJECTIVE: Hypotension after emergent endotracheal intubation is a serious complication related to in-hospital mortality. We investigated factors including modified shock index to predict the development of hypotension after emergent intubation. METHODS: This retrospective observational study was conducted between January 2011 and December 2016. The study population included intubated patients among all medical patients admitted to the emergency department (ED) except for patients whose systolic blood pressure was below 90 mmHg at any time before intubation. The postintubation hypotension (PIH) groups were compared with the non-PIH group. The secondary outcome was in-hospital mortality. RESULTS: A total of 285 patients were included in this study, of which 92 patients (32.3%) PIH. The age (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.01–1.06; P=0.001), serum albumin level (OR, 0.62; 95% CI, 0.41–0.92; P=0.019), shock index (OR, 3.25; 95% CI, 1.26–8.38; P=0.015), and modified shock index (MSI) (OR, 2.18; 95% CI, 1.06–4.47; P=0.034) were more closely associated with PIH than any other factors. The average survival of the PIH group was significantly shorter than that of the non-PIH group (13.6±3.5 vs. 35.6±12.0, log-rank test P=0.019). CONCLUSION: Overall, 32.3% of hemodynamically stable medical patients developed PIH in ED. MSI was associated with PIH.

About 5~12% of school-aged children suffer from the Attention-Deficit/Hyperactivity Disorder (ADHD). However, the core mechanism of ADHD remains unclear. G protein-coupled receptor kinase-interacting protein-1 (GIT1) has recently been reported to be associated with ADHD in human and the genetic deletion of GIT1 result in ADHD-like behaviors in mice. Mice lacking GIT1 shows a shift in neuronal excitation/inhibition (E/I) balance. However, the pricise mechanism for E/I imbalance and the role of neuron-glia interaction in GIT1 knockout (KO) mice have not been studied. Especially, a possible contribution of glial GABA and tonic inhibition mediated by astrocytic GABA release in the mouse model for ADHD remains unexplored. Therefore, we investigated the changes in the amount of GABA and degree of tonic inhibition in GIT1 KO mice. We observed a decreased glial GABA intensity in GIT1 KO mice compared to wild type (WT) mice and an attenuation of tonic current from cerebellar granule cells in GIT1 KO mice. Our study identifies the previously unknown mechanism of reduced astrocytic GABA and tonic inhibition in GIT1 lacking mice as a potential cause of hyperactivity disorder.

Cutibacterium acnes, a commensal, lipophilic, anaerobic Gram-positive bacterium, is well known for its potential to cause infections, particularly in the field of orthopedics, notably in the shoulder. However, its indolent strain nature presents challenges in the diagnosis of the bacterium using clinical, laboratory, and culture-based methods. There are controversies surrounding its actual threat as an infection-causing agent, leading to an incomplete consensus on treatment strategies after the infection. Furthermore, research is ongoing to explore preventive procedures before the onset of infection. This review aimed to comprehensively explore the diagnosis and treatment of C. acnes and determine whether it is a risk factor for shoulder joint infections.
