The COVID-19 pandemic has led to increased staffing needs in emergency departments. The question quickly arose as to whether it was appropriate to offer medical students the opportunity to assist this staff. The dilemma stems in part from the potential impact on their psychological well-being as well as their academic and clinical performances. ⋯ Employment site, including COVID first-line units, was not correlated with anxiety. Working in the clinical setting during the COVID-19 outbreak is not a risk factor for anxiety in medical students. Instead, it is an active coping strategy, suggesting that there are no barriers to allowing students to return to clinical settings during a pandemic, including first-line units, in terms of their psychological well-being.

COVID-19 diagnosis relies on molecular testing for SARS-CoV-2 via nasopharyngeal swab in the presence of suggestive clinical, radiological and laboratory findings. Since bronchoalveolar lavage liquid (BAL) collected during fibrobronchoscopy may increase test sensitivity compared to nasopharyngeal swabs, it was performed during the 2020 pandemic in clinically or radiologically suspected cases. Our aim was to determine whether clinical features, chest computed tomography (CT) findings or laboratory tests may predict patients testing positive for SARS-CoV-2 at BAL after a negative nasopharyngeal swab. ⋯ The procedure was well tolerated-with only one desaturation episode-while no healthcare worker was infected. In conclusion, when nasopharyngeal swabs are negative but there is clinical or imaging suspicion of COVID-19, BAL represents a complementary diagnostic tool, particularly in conjunction with suggestive/more extensive lung involvement at CT scan. The procedure did not carry increased risks for patients nor for operators, while allowing to free hospital resources, avoiding unnecessary isolations.

In recent years, many studies showed that the Trauma Mortality Probability Model (TMPM-ICD-9) had better calibration compared to other ICD-9-based models and to the ones based to the Abbreviated Injury Scale (AIS). The study aims to assess the validity of TMPM-ICD-9 in predicting injury severity in an Italian region and, through this model, to assess the performances of the Trauma Systems SIAT Romagna. ⋯ Present analysis proved the validity of TMPM-ICD-9 in predicting mortality of trauma patients in an Italian region. Furthermore, the usefulness of data extracted from an administrative database to assess the performance of a TS and the importance of an adequate centralization process have emerged. Even with a higher TMPM-POD and with the same mortality rate, HUB showed a higher spleen salvage rate compared to SPOKE + PST. However, thanks to this model, an improvable centralization process in SIAT Romagna was found in the study period. Probably, an enhanced centralization would have improved the spleen salvage rate, which is an important quality indicator in the evaluation of the performance of the TS.

Low-dose dexamethasone reduces mortality in patients with coronavirus disease 2019 (COVID-19)-related acute respiratory distress syndrome (ARDS). We retrospectively analyzed the efficacy of high-dose dexamethasone in patients with COVID-19-related ARDS and evaluated factors affecting the composite outcome (death or invasive mechanical ventilation). From March 4th to April 1st 2020, 98 patients with COVID-19 pneumonia were included. ⋯ In hospitalized patients with COVID-19-related ARDS, high-dose dexamethasone rapidly improves the clinical status and decreases inflammatory biomarkers. CVD was found to increase the risk of the composite outcome. These data support the importance of randomized clinical trials with high-dose dexamethasone in COVID-19 patients.

Persistent inflammation, immunosuppression and catabolism syndrome (PICS) in critically ill patients are associated with unreliable creatinine (Cr)-based estimated glomerular filtration rate (eGFR) and alteration in vancomycin clearance (CL) due to ongoing muscle wasting and renal dysfunction (RD). Currently, cystatin C (Cys) is of great interest for eGFR due to its muscle independence. Patients receiving intravenous vancomycin with trough concentration monitoring after intensive care unit stay ≥ 14 days were retrospectively enrolled. ⋯ External validation with 34 Ctrough showed the robustness and accuracy of this model. This study showed the negative impact of PICS on Cr-guided vancomycin trough achievement. PPK model with CKD-EPIcys-cr can be used to optimize vancomycin dosage in patients with PICS.
