Since the end of 2019, an outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), originating in the Chinese city of Wuhan has spread rapidly worldwide causing thousands of deaths. Coronavirus disease (COVID-19) is supported by SARS-CoV-2 and represents the causative agent of a potentially fatal disease that is of great global public health concern. Italy has been the first European country recording an elevated number of infected forcing the Italian Government to call for total lockdown. The lockdown had the aim to limit the spread of infection through social distancing. The purpose of this study is to analyze how the pandemic has affected the patient's accesses to the Ophthalmological Emergency Department of a tertiary referral center in central-northern Italy, during the lockdown period. The charts of all patients that came to the Emergency Department during the lockdown period (March 10 -May 4, 2020) have been retrospectively collected and compared with those in the same period of 2019 and the period from 15 January- 9 March 2020. A significant reduction of visits during the lockdown has been observed, compared with those of pre-lockdown period (reduction of 65.4%) and with those of the same period of 2019 (reduction of 74.3%). Particularly, during the lockdown, minor and not urgency visits decreased whereas the undeferrable urgency ones increased. These pieces of evidence could be explained by the fear of patients to be infected; but also revealed patients misuse of emergency services.

Background: Sepsis remains a leading cause of mortality worldwide, and understanding endothelial damage is crucial for improving patient outcomes. Endothelial dysfunction in sepsis contributes to coagulopathy, increased capillary permeability, and vasoplegia, but the interplay between these processes remains underexplored. The study aims to evaluate the clinical relationship between those factors due to sepsis-induced endothelial damage. Methods: A prospective single-center study on 75 community-acquired septic patients admitted to an Intermediate Care Unit. The Sepsis-Induced Coagulopathy (SIC) score, serum albumin (as a surrogate for capillary leak), and Total Peripheral Resistance Index (TPRI) (as a surrogate for vasoplegia) were assessed. Structural Equation Modeling (SEM) explored the relationship between variables, hypothesizing a common latent factor (endothelial damage). Principal Component Analysis assessed the shared variance among variables. Results: The mean SIC score was 3.4 (SD 1.3), with 44% of patients affected. TPRI and albumin had mean values of 1954 (SD 738) and 2.58 (SD 0.59), respectively, both negatively correlated with SIC: TPRI −0.263 (p = 0.023) and albumin −0.454 (p < 0.001). SEM showed SIC, albumin, and TPRI are associated with a latent factor (endothelial damage), explaining 68% of the variance (CFI = 1.000, RMSEA = 0.000). Albumin was inversely correlated (p = 0.004), and TPRI was significantly associated (p = 0.003). Conclusions: This pilot study suggests that coagulopathy, increased vascular permeability, and vasoplegia may be clinically interrelated manifestations of endothelial injury in sepsis. These findings support the feasibility of modeling a unified pathophysiological construct using accessible bedside data, potentially guiding future individualized approaches in sepsis management.

Background/Objectives: Dyspnea is one of the main causes of visits to the Emergency Department (ED) and hospitalization, with its differential diagnosis representing a challenge for the clinician. Lung ultrasound (LUS) is a widely used tool in ED. The objective of this study was to evaluate the impact of LUS, performed by a non-expert operator, in determining diagnosis and prognosis of patients with dyspnea. Methods: A total of 60 patients presenting with dyspnea at the ED were prospectively enrolled and underwent LUS examination by a medical student, after brief training, within 3 h of triage. LUS findings were classified into four patterns: N.1, absence of notable ultrasound findings, attributable to COPD/ASMA exacerbation; N.2, bilateral interstitial syndrome, suggestive of acute heart failure; N.3, subpleural changes/parenchymal consolidations, suggestive of pneumoniae; and N.4, isolate polygonal triangular consolidation, attributable to infarction in the context of pulmonary thromboembolism. Results: The diagnostic hypothesis formulated after LUS was compared with the final diagnosis after further investigations in the ED, showing agreement in 90% of cases. The mean LUS score value was higher in patterns N.2 (18.4 ± 8.5) and N.3 (17 ± 6.6), compared to patterns N.1 and N.4 (9.8± 6.7 and 11.5 ± 2.1). Given the high prevalence of pattern N.2, the diagnostic accuracy of LUS in this context was further evaluated, showing a sensitivity of 82% and specificity of 100%. In terms of the prognostic value of LUS, hospitalized patients had a higher LUS score compared to those discharged (17.3 ± 8.1 vs. 8.5 ± 6.8, p value 0.004). A similar trend was obtained in the subgroup of patients requiring non-invasive ventilation (NIV), who present a higher LUS score (21.1 ± 6.6 vs. 13.1 ± 8.1, p value 0.002). When considering a combined outcome (death and NIV), patients with worse outcomes more often had a LUS score > 15 (p value < 0.001). Conclusions: In conclusion, this study confirms that LUS is a very useful tool in the ED, assisting the clinical evaluation for diagnosis, treatment decision, and determination of the appropriate care setting for patients with acute dyspnea. Its short learning curve allows even non-expert staff to use it effectively.

Repeat head CT in patients on direct oral anticoagulant therapy (DOACs) with minor traumatic brain injury (MTBI) after an initial CT scan without injury on arrival in the Emergency Department (ED) is a common clinical practice but is not based on clear evidence. To assess the incidence of delayed intracranial haemorrhage (ICH) in patients taking DOACs after an initial negative CT and the association of clinical and risk factors presented on patient arrival in the ED. This retrospective multicentre observational study considered patients taking DOACs undergoing repeat CT after a first CT free of injury for the exclusion of delayed ICH after MTBI. Timing between trauma and first CT in the ED and pre- or post-trauma risk factors were analysed to assess a possible association with the risk of delayed ICH. A total of 1426 patients taking DOACs were evaluated in the ED for an MTBI. Of these, 68.3% (916/1426) underwent a repeat CT after an initial negative CT and 24 h of observation, with a rate of delayed ICH of 1.5% (14/916). Risk factors associated with the presence of a delayed ICH were post-traumatic loss of consciousness, post-traumatic amnesia and the presence of a risk factor when the patient presented to the ED within 8 h of the trauma. None of the patients with delayed ICH at 24-h repeat CT required neurosurgery or died within 30 days. Delayed ICH is an uncommon event at the 24-h control CT and does not affect patient outcome. Studying the timing and characteristics of the trauma may indicate patients who may benefit from more in-depth management.

Although mild traumatic brain injury (MTBI) in people on oral anticoagulant treatment (OAT) is a frequent challenge for Emergency Department (ED), strong guidelines recommendations are lacking. In the attempt to assess the safety profile of direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs), we have recruited 473 patients with a MTBI on OAT (43.6% males; age 81.8 ± 8.7 years), admitted to the Pisa’s University Hospital ED (Jan 2016—Oct 2018). All patients underwent a head CT scan with those with no sign of acute bleedings remaining under clinical observation for the ensuing 24 h. Fifty patients (10.6%, 95% CI: 8.1–13.7%) had immediate intracranial hemorrhage (ICH), with a prevalence of patient-important outcomes due to immediate ICH of 1.1% (95% CI 0.4–2.4%); 3 patients died (0.6%, 95% CI 0.2–1.8) and 2 required neurosurgical intervention. Immediate ICHs were more frequent in VKA-treated than in DOAC-treated patients (15.9 vs. 6.4%. RR 2.5. 95%CI 1.4–4.4. p < 0.05). Multivariate analysis identified that post-traumatic amnesia, evidence of trauma above clavicles, high blood glucose, high blood pressure (BP) at arrival, and low prothrombin activity were predictors of immediate ICH. The prevalence of delayed ICH was 1.0% (95%CI 0.4–2.5%) without differences between DOACs and VKAs. Despite ICH being a frequent complication of MTBI in patients on OAT, immediate and delayed patient-important outcomes are rare. DOACs have a better safety profile than VKAs. Simple clinical parameters such as blood pressure at arrival or blood glucose might provide useful predictors of immediate ICH.Trial registration number: 11924_CIPRIANO.

Background Nomograms are easy-to-handle clinical tools which can help in estimating the risk of adverse outcome in certain population. This multi-center study aims to create and validate a simple and usable clinical prediction nomogram for individual risk of post-traumatic Intracranial Hemorrhage (ICH) after Mild Traumatic Brain Injury (MTBI) in patients treated with Direct Oral Anticoagulants (DOACs). Methods From January 1, 2016 to December 31, 2019, all patients on DOACs evaluated for an MTBI in five Italian Emergency Departments were enrolled. A training set to develop the nomogram and a test set for validation were identified. The predictive ability of the nomogram was assessed using AUROC, calibration plot, and decision curve analysis. Results Of the 1425 patients in DOACs in the study cohort, 934 (65.5%) were included in the training set and 491 (34.5%) in the test set. Overall, the rate of post-traumatic ICH was 6.9% (7.0% training and 6.9% test set). In a multivariate analysis, major trauma dynamic (OR: 2.73, p = 0.016), post-traumatic loss of consciousness (OR: 3.78, p = 0.001), post-traumatic amnesia (OR: 4.15, p < 0.001), GCS < 15 (OR: 3.00, p < 0.001), visible trauma above the clavicles (OR: 3. 44, p < 0.001), a post-traumatic headache (OR: 2.71, p = 0.032), a previous history of neurosurgery (OR: 7.40, p < 0.001), and post-traumatic vomiting (OR: 3.94, p = 0.008) were independent risk factors for ICH. The nomogram demonstrated a good ability to predict the risk of ICH (AUROC: 0.803; CI95% 0.721–0.884), and its clinical application showed a net clinical benefit always superior to performing CT on all patients. Conclusion The Hemorrhage Estimate Risk in Oral anticoagulation for Mild head trauma (HERO-M) nomogram was able to predict post-traumatic ICH and can be easily applied in the Emergency Department (ED).

High sensitivity troponin T (hsTnT) is a strong predictor of adverse outcome during SARS-CoV-2 infection. However, its determinants remain partially unknown. We aimed to assess the relationship between severity of inflammatory response/coagulation abnormalities and hsTnT in Coronavirus Disease 2019 (COVID-19). We then explored the relevance of these pathways in defining mortality and complications risk and the potential effects of the treatments to attenuate such risk. In this single-center, prospective, observational study we enrolled 266 consecutive patients hospitalized for SARS-CoV-2 pneumonia. Primary endpoint was in-hospital COVID-19 mortality. hsTnT, even after adjustment for confounders, was associated with mortality. D-dimer and CRP presented stronger associations with hsTnT than PaO 2 . Changes of hsTnT, D-dimer and CRP were related; but only D-dimer was associated with mortality. Moreover, low molecular weight heparin showed attenuation of the mortality in the whole population, particularly in subjects with higher hsTnT. D-dimer possessed a strong relationship with hsTnT and mortality. Anticoagulation treatment showed greater benefits with regard to mortality. These findings suggest a major role of SARS-CoV-2 coagulopathy in hsTnT elevation and its related mortality in COVID-19. A better understanding of the mechanisms related to COVID-19 might pave the way to therapy tailoring in these high-risk individuals.

Cancer is characterized by chronic inflammation and hypercoagulability, with an excess of venous thromboembolism (VTE). Tissue factor, the initiator of blood coagulation, circulates associated with extracellular vesicles (EV-TF). Studies investigating EV-TF between cancer-associated and non-cancer-associated VTE are lacking. We therefore compared EV-TF in unprovoked VTE (U-VTE), cancer-associated VTE (C-VTE), and cancer without VTE (C-w/o VTE). We also investigated interleukin-6 (IL-6) levels between the same groups. The final population included 68 patients (U-VTE: n = 15; C-VTE: n = 24; C-w/o VTE: n = 29). All patients with VTE were enrolled within 48 h of diagnosis; non-VTE patients were recruited in the oncologic outpatient services. EV were isolated by differential centrifugation from 4 mL of peripheral blood; the final EV pellet (16,000× g for 45 min) was resuspended in 100 μL saline and tested for TF using a one-step clotting assay. There was a statistically significant difference for higher EV-TF in C-VTE and C-w/o VTE compared to U-VTE (p = 0.024; Kruskal–Wallis test). There was no significant difference between C-VTE and C-w/o VTE. Moreover, we did not find any difference in IL-6 levels. These preliminary data suggest that cancer represents, per se, a strong driver of EV-TF generation.

Background: Sepsis-induced coagulopathy (SIC) and hypoalbuminemia represent distinct yet interrelated manifestations of endothelial dysfunction in sepsis. While both have been individually associated with increased mortality, their combined prognostic value remains unexplored. This study aimed to assess the relationship between the SIC score and serum albumin levels and to evaluate their integrated role in predicting mortality and bleeding risks in septic patients. Methods: We conducted a prospective observational study enrolling adult patients with community-acquired sepsis admitted to an Intermediate Medical Care Unit between January 2023 and June 2024. The primary outcome was 30-day all-cause mortality. The secondary outcome was the occurrence of ISTH-defined major bleeding. Multivariable logistic regression and Net Reclassification Improvement (NRI) analyses were performed to evaluate the predictive value of albumin when added to the SIC score. Results: A total of 413 patients were enrolled; 18.4% had a positive SIC score. The serum albumin and SIC score were inversely correlated (r = −0.189, p < 0.001). Both variables were independently associated with 30-day mortality and major bleeding. The addition of albumin significantly improved the predictive performance of the SIC score (NRI = 0.276 for mortality; NRI = 0.268 for bleeding; both p = 0.003). The cluster analysis identified distinct phenotypes based on albumin and SIC profiles, with differing clinical trajectories and transfusion needs. Conclusions: The combined assessment of the SIC score and serum albumin enhances early risk stratification in sepsis. This dual-parameter approach may support more accurate prognostication and individualized management in septic patients.

The study aimed to validate the Manchester Triage System in a hospital setting using data for short- and medium-term death rates. A prospective observational study was conducted at the Emergency Department of Merano Hospital for two years. The discriminatory ability of MTS was tested using AUROCs and contingency tables, reporting sensitivity and specificity levels for each study outcome. A total of 98,443 patients were enrolled, 237 of whom died within 72h; 422 patients died within seven days, and 1025 died within 30 days. The MTS demonstrated excellent discriminatory ability, reporting AUROC values of 0.890 for death within 72h, 0.853 for death within seven days, and 0.781 for death within 30 days. A sensitivity of 87.7% and a specificity of 79.4% were reported for death at 72h, while a sensitivity of 69.6% and a specificity of 79.8% were reported for death at 30 days. The MTS has proven to be a good triage system capable of accurately identifying patients who are at risk of death in the short or medium term.
