Exacerbations of chronic obstructive pulmonary disease (COPD) are episodes of acute worsening of respiratory symptoms that require additional therapy. These events play a pivotal role in the natural course of the disease and are associated with a progressive decline in lung function, reduced health status, a low physical activity level, tremendous health care costs, and increased mortality. Although most exacerbations have an infectious origin, the underlying mechanisms are heterogeneous and specific predictors of their occurrence in individual patients are currently unknown. ⋯ At present, microbial composition and host-microbiome interactions in the lung are increasingly recognized for their role in affecting the susceptibility to exacerbations, and may steer towards a novel direction in the management of COPD exacerbations. This narrative review describes the current challenges and unmet needs in the management of acute exacerbations of COPD. Exacerbation triggers, biological clusters, current treatment strategies, and their limitations, previously studied biomarkers and prediction tools, the lung microbiome and its role in COPD exacerbations as well as future directions are discussed.

Multicenter Study
Analysis of fatal adverse drug events recorded in several Italian emergency departments (the MEREAFaPS study).
Fatal Adverse Events (FADEs) are a major public health problem, and some FADEs could be preventable. The aim of the present study is to describe the frequency, the drugs involved and the preventability in the FADEs collected through the MEREAFaPS Study between 2012 and 2018. All cases including the outcome "death" have been examined. ⋯ This study confirms that FADEs are still a relevant clinical occurrence, and are often caused by widely used old drugs associated with adverse events. The death of one in four patients was preventable. Further efforts should be done to improve the appropriateness of the therapy, especially in older patients who are treated with anticoagulants.

The emerging outbreak of the coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to spread worldwide. We prescribed some promising medication to our patients with mild to moderate pneumonia due to SARS-CoV-2, however such drugs as chloroquine, hydrossichloroquine, azithromycin, antivirals (lopinavir/ritonavir, darunavir/cobicistat) and immunomodulating agents (steroids, tocilizumab) were not confirmed as effective against SARS-CoV2. We, therefore, started to use auto-hemotherapy treated with an oxygen/ozone (O2/O3) gaseous mixture as adjuvant therapy. ⋯ No adverse events were observed associated with the application of O2/O3 gaseous mixture. O2/O3 therapy as adjuvant therapy could be useful in mild to moderate pneumonia due to SARS-CoV-2. Randomized prospective study is ongoing [Clinical Trials.gov ID: Z7C2CA5837].

Observational Study
Prognostic stratification in septic patients with overt and cryptic shock by speckle tracking echocardiography.
We evaluated the prevalence and prognostic value of left (LV) and right (RV) ventricular systolic dysfunction in the presence of overt and cryptic shock. In this prospective study, between October 2012 and June 2019, we enrolled 354 patients with sepsis, 41% with shock, among those admitted to the Emergency Department High-Dependency Unit. Patients were grouped based on the presence of shock, or by the presence of lactate levels ≥ (LAC +) or < 2 mmol/L (LAC-) evaluated within the first 24 h. ⋯ In patients without shock, as well as in those LAC-, LV dysfunction was associated with increased day-28 mortality rate (78% vs 57% in non-survivors and survivors without shock and 74% vs 53% in non-survivors and survivors LAC-, all p < 0.01). LV (RR 2.26, 95% CI 1.37-3.74) and RV systolic dysfunction (RR 1.85, 95% CI 1.22-2.81) were associated with increased 28-day mortality rate in addition and independent to LAC + (RR 1.81, 95% CI 1.15-2.84). In conclusion, LV and RV ventricular dysfunction were independently associated with an increased mortality rate, altogether with the presence of cryptic shock.

The slowness of dripping and the presence of alcohol have been offered/suggested as possible causes for the increased risk of developing dependence to the oral formulation of lormetazepam rather than to other anxiolytic and hypnotic drugs. We hence assessed the time of dripping of the most used benzodiazepines and z-drugs oral solution products under experimental conditions and the different employed excipients through a comparative analysis of the Summaries of Product Characteristics. A wide range of the median overall dispensing time was found across the eight products included in the analysis. ⋯ More precisely, the quantity of alcohol per bottle has been found negligible at therapeutic doses; however, when these are exceeded, they may have clinical implications for patients. Further studies are needed to assess them. Meanwhile, the public-health problem remains and some improvements should be carried out at different levels, to guarantee the appropriate prescription and use of lormetazepam oral solution.
