Observational Study
Association between laboratory parameters and CT severity in patients infected with Covid-19: A retrospective, observational study.
Patients diagnosed with COVID-19 have presented to emergency departments (EDs) worldwide with a wide range of symptoms. In this study we reported the clinical, laboratory and radiological features of the cases diagnosed with COVID-19. ⋯ In our study, serum ferritin and D-dimer levels were observed to be high in the CT-positive group and have moderate positive correlation with CT severity. We thus argue that D-dimer and ferritin levels measured at the time of admission to the ED can be taken into consideration to predict radiological severity.

Background Delayed encephalopathy (DE) is the most severe complication after acute carbon monoxide (CO) poisoning, which seriously affects the outcome of patients and leads to a high disability rate. Prior studies have shown that hyperbaric oxygen (HBO2) therapy is therapeutic for DE due to reducing immune-mediated neuropathology and thus improving cognitive performance. Methods In our present perspective study, five DE patients were treated regularly with HBO2 therapy. ⋯ Conclusion The application of HBO2 therapy is of significance in improving the cognition of DE patients, along with mobilized circulating stem cells. We primarily infer that the CD34+/CD90+ and CD34+/CD133+ cells were mobilized by HBO2 exposure and have played a positive role in cognition improvement on DE patients by up-regulation of BDNF, nestin and SYP. The altering amount of circulating stem cells mobilized in peripheral blood could be a potential marker on predicting the outcome of DE.

Observational Study
Decreased hospital admissions through emergency departments during the COVID-19 pandemic.
Emergency Department (ED) visits decreased significantly in the United States during the COVID-19 pandemic. A troubling proportion of this decrease was among patients who typically would have been admitted to the hospital, suggesting substantial deferment of care. We sought to describe and characterize the impact of COVID-19 on hospital admissions through EDs, with a specific focus on diagnosis group, age, gender, and insurance coverage. ⋯ Our findings demonstrate decreased hospital admissions through EDs during the pandemic and suggest that several patient populations may have deferred necessary care. Further research is needed to determine the clinical and operational consequences of this delay.

Helicopter emergency medical services (HEMS) is commonly elected transport for acute ischemic stroke (AIS) known as a time-critical illness. ⋯ HEMS necessity varied considerably between studies. More robust studies are needed for detection of the most suitable use of HEMS in AIS.

To characterize injuries caused by exercise resistance bands. ⋯ Exercise resistance bands can cause a wide spectrum of ocular injuries, some leading to long-term vision loss. As such, we recommend that patients strongly consider using eye protection goggles or glasses while using resistance bands for exercise.
