Predictive value of diaphragm ultrasound for mechanical ventilation outcome in patients with acute exacerbation of chronic obstructive pulmonary disease.

Background: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is often combined with respiratory failure, which increases the patient's morbidity and mortality. Diaphragm ultrasound (DUS) has developed rapidly in the field of critical care in recent years. Studies with DUS monitoring diaphragm-related rapid shallow breathing index have demonstrated important results in guiding intensive care unit patients out of the ventilator.

Forecasting of Beijing PM with a hybrid ARIMA model based on integrated AIC and improved GS fixed-order methods and seasonal decomposition.

Accurate particulate matter 2.5 (PM) prediction plays a crucial role in the accurate management of air pollution and prevention of respiratory diseases. However, PM, as a nonlinear time series with great volatility, is difficult to achieve accurate prediction.

Population Dynamics of Patients with Bacterial Resistance in Hospital Environment.

During the past decades, the increase of antibiotic resistance has become a major concern worldwide. The researchers found that superbugs with new type of resistance genes (NDM-1) have two aspects of transmission characteristics; the first is that the antibiotic resistance genes can horizontally transfer among bacteria, and the other is that the superbugs can spread between humans through direct contact. Based on these two transmission mechanisms, we study the dynamics of population in hospital environment where superbugs exist.
