Risk Stratification in COVID-19 Pneumonia - Determining the Role of Lung Ultrasound.

LUS patterns of COVID-19 pneumonia have been described and shown to be characteristic. The aim of the study was to predict the prognosis of patients with COVID-19 pneumonia, using a score based on LUS findings. MATERIALS AND METHODS: An observational, retrospective study was conducted on patients admitted to Niguarda hospital with a diagnosis of COVID-19 pneumonia during the period of a month, from March 2nd to April 3rd 2020. Demographics, clinical, laboratory, and radiological findings were collected. LUS was performed in all patients. The chest was divided into 12 areas. The LUS report was drafted using a score from 0 to 3 with 0 corresponding to A pattern, 1 corresponding to well separated vertical artifacts (B lines), 2 corresponding to white lung and small consolidations, 3 corresponding to wide consolidations. The total score results from the sum of the scores for each area. The primary outcome was endotracheal intubation, no active further management, or death. The secondary outcome was discharge from the emergency room (ER). RESULTS: 255 patients were enrolled. 93.7 % had a positive LUS. ETI was performed in 43 patients, and 24 received a DNI order. The general mortality rate was 15.7 %. Male sex (OR 3.04, p = 0.014), cardiovascular disease and hypertension (OR 2.75, p = 0.006), P/F (OR 0.99, p < 0.001) and an LUS score > 20 (OR 2.52, p = 0.046) were independent risk factors associated with the primary outcome. Receiver operating characteristic (ROC) curve analysis for an LUS score > 20 was performed with an AUC of 0.837. Independent risk factors associated with the secondary outcome were age (OR 0.96, p = 0.073), BMI (OR 0.87, p = 0,13), P/F (OR 1.03, p < 0.001), and LUS score < 10 (OR 20.9, p = 0.006). ROC curve analysis was performed using an LUS score < 10 with an AUC 0.967. CONCLUSION: The extent of lung abnormalities evaluated by LUS score is a predictor of a worse outcome, ETI, or death. Moreover, the LUS score could be an additional tool for the safe discharge of patient from the ER.

A pilot study on the application of the current European guidelines for the management of acute coronary syndrome without elevation of ST segment (NSTEMI) in the Emergency Department setting in the Italian region Lazio.

BACKGROUND: In 2011 the European Society of Cardiology published the new guidelines for the treatment and management of acute coronary syndrome without elevation of the ST segment (NSTEMI). For the treatment of the syndrome, the use of P2Y12 inhibitors in addition to aspirin was strongly recommended (evidence IA). We studied the application of this recommendation in the setting of the emergency department in the vast and uneven area of the Italian region Lazio, three years after the release of these drugs in Italy. METHODS: 121 consecutive patients (65% older than 65 years) affected by NSTEMI were recruited between May and July 2013. During the transition in the emergency department data was collected on patient's symptoms, syndrome severity and type & timing of treatments chosen. Adherence to the guidelines was evaluated considering the number of "good treated" patients: these being the patients that received at least 80% of the main five recommendations on percutaneous coronary intervention (PCI) timing, antiplatelet and anti-coagulant therapy suggested by the European Cardiology Task Force (ESC guidelines, 2011) for the very acute phase of NSTEMI. RESULTS: Patients were treated with: 1) 35% of cases with double antiplatelet therapy and anticoagulation (DAPT+AC), 2) 22% of cases with single antiplatelet and anticoagulation (SAPT+AC), 3) 6% of cases with a single antiplatelet therapy (SAPT), 4) 6% of cases with a double antiplatelet therapy (DAPT) and 5) 24% of cases did not receive any therapy. Data on PCI was available for 95 patients and, of these, only 82% of the patients underwent the procedure. The percentage of "good treated" patients were among of 20-40%, depending on PCI timing--as guidelines suggested--was considered as mandatory (20,5%) or as the extreme time limit (40%). Significant differences were found between patients treated in a central hospital with a hemodynamic laboratory active 24/24hr (HUB) and patients treated in the other hospital (SPOKE). HUBs showed a higher percent of "good treated" patients, a higher percentage of early invasive treated and a better adherence to recommended pharmacological therapy. CONCLUSIONS: A significant number of patients did not receive adequate treatment during the emergency department stay. The absence of hemodynamic services increases the risk of inadequate treatment.

Rhinovirus frequently detected in elderly adults attending an emergency department.

The general aim was to investigate the burden of respiratory virus illness in a hospital emergency department, during two different epidemic seasons. Consecutive patients attending an emergency department during two study periods (February/March 2009 and 2010) were enrolled using broad inclusion criteria (fever/preceding fever and one of a set of ICD-9 codes suggestive of respiratory illness); nasopharyngeal washes were tested for the most common respiratory viruses using PCR-based methods. Influenza A virus was detected in 24% of samples collected in February/March 2009, whereas no samples tested positive for influenza during February/March 2010 (pandemic H1N1 Influenza A having circulated earlier in October-December 2009). Rhinovirus (HRV) was detected in 16% and 8% of patients recruited over the two study periods, respectively. Other respiratory viruses were detected rarely. Patient data were then analyzed with specific PCR results, comparing the HRV-positive group with virus-positive and no virus-detected groups. Individuals over 65 years old with HRV presented with signs, symptoms and underlying conditions and were admitted to hospital as often as the other enrolled patients, mainly for dyspnoea and chronic obstructive pulmonary disease acute exacerbation. Conversely, younger individuals with HRV, although presenting with respiratory signs and symptoms, were generally diagnosed with non-respiratory conditions. HRV was detected frequently in elderly patients attending the emergency department for respiratory distress without distinguishing clinical features. Molecular diagnosis of lower respiratory tract infections and surveillance of infectious diseases should include tests for HRV, as this virus is associated frequently with hospitalization of the elderly.
