Background: Pregnancy is a complex time characterized by major transformations in a woman, which impact her physical, mental, and social well-being. How a woman adapts to these changes can affect her quality of life and psychological well-being. The literature indicates that pregnant women commonly experience psychological symptoms, with anxiety, stress, and depression being among the most frequent. Hence, promoting a healthy lifestyle focused on women's psychological well-being is crucial. Recently developed digital solutions have assumed a crucial role in supporting psychological well-being in physiologically pregnant women. Therefore, the need becomes evident for the development and implementation of digital solutions, such as a virtual coach implemented in a smartphone, as a support for the psychological well-being of pregnant women who do not present psychological and psychiatric disorders., Objective: This study aims to assess the feasibility, acceptability, and utility of a mindfulness-based mobile app. The primary objective is to explore the feasibility of using a virtual coach, Maia, developed within the TreC Mamma app to promote women's psychological well-being during pregnancy through a psychoeducational module based on mindfulness. Finally, through the delivery of this module, the level of psychological well-being will be explored as a secondary objective., Methods: This is a proof-of-concept study in which a small sample (N=50) is sufficient to achieve the intended purposes. Recruitment will occur within the group of pregnant women belonging to the pregnancy care services of the Trento Azienda Provinciale per i Servizi Sanitari di Trento. The convenience sampling method will be used. Maia will interact with the participating women for 8 weeks, starting from weeks 24 and 26 of pregnancy. Specifically, there will be 2 sessions per week, which the woman can choose, to allow more flexibility toward her needs., Results: The psychoeducational pathway is expected to lead to significant results in terms of usability and engagement in women's interactions with Maia. Furthermore, it is anticipated that there will be improvements in psychological well-being and overall quality of life. The analysis of the data collected in this study will be mainly descriptive, orientated toward assessing the achievement of the study objectives., Conclusions: Literature has shown that women preferred web-based support during the perinatal period, suggesting that implementing digital interventions can overcome barriers to social stigma and asking for help. Maia can be a valuable resource for regular psychoeducational support for women during pregnancy., International Registered Report Identifier (irrid): RR1-10.2196/53890., (©Silvia Rizzi, Stefania Poggianella, Maria Chiara Pavesi, Lorenzo Gios, Giorgia Bincoletto, Isabella Scolari, Claudia Paoli, Debora Marroni, Irene Tassinari, Barbara Baietti, Anna Gianatti, Veronica Albertini, Barbara Burlon, Vanda Chiodega, Barbara Endrizzi, Elena Benini, Chiara Guella, Erik Gadotti, Stefano Forti, Fabrizio Taddei.

In patients with acute circulatory failure, we tested the feasibility of the evaluation of the fluid-responsiveness (FR) by a combined approach with echocardiography and lung ultrasound. We enrolled 113 consecutive patients admitted to the Emergency Department High-Dependency Unit of Careggi University-Hospital from January 2015 to June 2020. We assessed: (1) inferior vena cava collapsibility index (IVCCI); (2) the variation of aortic flow (VTIAo) during the passive leg raising test (PLR); (3) the presence of interstitial syndrome by lung ultrasound. FR was defined as an increase in the VTIAo > 10% during PLR or IVCCI ≥ 40%. FR patients were treated with fluid and those non-FR with diuretics or vasopressors. The therapeutic strategy was reassessed after 12 h. The goal was to maintain the initial strategy. Among 56 FR patients, at lung ultrasound, 15 patients showed basal interstitial syndrome and 4 all-lung involvement. One fluid bolus was given to 51 patients. Among 57 non-FR patients, 26 patients showed interstitial syndrome at lung ultrasound (basal fields in 14, all lungs in 12). We administered diuretics to 21 patients and vasopressors to 4 subjects. We had to change the initial treatment plan in 9% non-FR patients and in 12% FR patients (p = NS). In the first 12 h after the evaluation, non-FR patients received significantly less fluids compared to those FR (1119 ± 410 vs 2010 ± 1254 ml, p < 0.001). The evaluation of the FR based on echocardiography and lung ultrasound was associated with the reduction in fluid administration for non-FR patients compared with those FR., (© 2023. The Author(s).)

We evaluated the effectiveness of a training program with high-fidelity simulation (HFS) to improve technical (TS) and non-technical skills (NTS) of residents in Emergency Medicine. We conducted a 2-year training program for the management of a critical patient based on HFS (6 sessions for every year, four teams who performed 4 scenarios per session). At the beginning of the training program, all participants received a presentation of Crisis Resource Management (CRM) principles. Each session covered a different topic in Emergency Medicine Curriculum. TSs were measured as the proportion of completed tasks in the following areas: airway, breathing, circulation, disability and exposure (ABCDE) assessment and management, completion of anamnesis based on AMPLE (allergy, medications, previous illness, last meal and event) scheme, diagnostic and therapeutic assessment. NTSs were rated by the Clinical Teamwork Scale (CTS). Scores' values and the percentage of correctly performed actions were presented as median with interquartile range. Friedmann non-parametric test was employed to evaluate the trend of TS and NTS over the following sessions. Among the TS, the assessment and management of ABCDE and completion of therapeutic tasks improved (all p < 0.05). The completion of diagnostic tasks (p = 0.050) tended toward significant improvement. The overall CTS score (first session 61 ± 17, last session 84 ± 16, p < 0.001) as well as Communication (first 13.7 ± 3.6, last 18.7 ± 3.5, p < 0.001), Situational Awareness (first 5.3 ± 1.8, last 6.4 ± 1.4, p = 0.012) and Role Responsibility subscores (first 9.7 ± 2.8, last 12.1 ± 3.7, p < 0.001) increased through the following sessions. Therefore, HFS has proven to be an effective instrument to improve TS and NTS among Emergency Medicine residents., (© 2022.

In the context of sepsis, we tested the relationship between echocardiographic findings and Troponin, and their impact on prognosis. In this prospective study, we enrolled 325 septic patients (41% with shock), not mechanically ventilated, between October, 2012 and June, 2019 among those admitted to our High-Dependency Unit. By echocardiography within 24 h from the admission, sepsis-induced myocardial dysfunction (SIMD) was defined as left ventricular (LV) systolic dysfunction (speckle-tracking-based global longitudinal peak systolic strain, GLS, >  - 14%) and/or right ventricular (RV) systolic dysfunction (Tricuspid Annular Plane Systolic Excursion, TAPSE < 16 mm). Troponin I levels were measured upon admission (T0) and after 24 h (T1); it was considered normal if > 0.1 ng/mL. Mortality was assessed at day-7 and day-28 end-points. One-hundred and forty-two patients had normal Troponin level at T0 and T1 (G1), 69 had abnormal levels at T0 or T1 (G2) and 114 showed abnormal Troponin levels at both T0 and T1 (G3). Compared to G1, patients in G3 had worse LV and RV systolic function (GLS  - 11.6 ± 3.4% vs  - 14.0 ± 3.5%, p < 0.001; TAPSE 18 ± 0.5 vs 19 ± 0.5 mm, p = 0.047) and greater day-28 (34% vs 20%, p = 0.015) mortality. In a Cox survival analysis including age, Troponin and SOFA score, mortality was predicted by the presence of SIMD (RR 3.24, 95% CI 1.72-6.11, p < 0.001) with no contribution of abnormal Troponin level. While abnormal Troponin levels were associated with SIMD diagnosed by echocardiography, only the presence of SIMD predicted the short- and medium-term mortality rate, without an independent contribution of increased Troponin levels., (© 2021.

Objective: The aim of this study was to assess the incidence of deep vein thrombosis (DVT) of the lower limbs, using serial compression ultrasound (CUS) surveillance, in acutely ill patients with COVID-19 pneumonia admitted to a non-ICU setting., Methods: Multicenter, prospective study of patients with COVID-19 pneumonia admitted to Internal Medicine units. All patients were screened for DVT of the lower limbs with serial CUS. Anticoagulation was defined as: low dose (enoxaparin 20-40 mg/day or fondaparinux 1.5-2.5 mg/day); intermediate dose (enoxaparin 60-80 mg/day); high dose (enoxaparin 120-160 mg or fondaparinux 5-10 mg/day or oral anticoagulation). The primary end-point of the study was the diagnosis of DVT by CUS., Results: Over a two-month period, 227 consecutive patients with moderate-severe COVID-19 pneumonia were enrolled. The incidence of DVT was 13.7% (6.2% proximal, 7.5% distal), mostly asymptomatic. All patients received anticoagulation (enoxaparin 95.6%) at the following doses: low 57.3%, intermediate 22.9%, high 19.8%. Patients with and without DVT had similar characteristics, and no difference in anticoagulant regimen was observed. DVT patients were older (mean 77±9.6 vs 71±13.1 years; p = 0.042) and had higher peak D-dimer levels (5403 vs 1723 ng/mL; p = 0.004). At ROC analysis peak D-dimer level >2000 ng/mL (AUC 0.703; 95% CI 0.572-0.834; p = 0.004) was the most accurate cut-off value able to predict DVT (RR 3.74; 95%CI 1.27-10, p = 0.016)., Conclusions: The incidence of DVT in acutely ill patients with COVID-19 pneumonia is relevant. A surveillance protocol by serial CUS of the lower limbs is useful to timely identify DVT that would go otherwise largely undetected., Competing Interests: The authors have declared that no competing interests exist.

Overwhelming inflammatory reactions contribute to respiratory distress in patients with COVID-19. Ruxolitinib is a JAK1/JAK2 inhibitor with potent anti-inflammatory properties. We report on a prospective, observational study in 34 patients with COVID-19 who received ruxolitinib on a compassionate-use protocol. Patients had severe pulmonary disease defined by pulmonary infiltrates on imaging and an oxygen saturation ≤ 93% in air and/or PaO2/FiO2 ratio ≤ 300 mmHg. Median age was 80.5 years, and 85.3% had ≥ 2 comorbidities. Median exposure time to ruxolitinib was 13 days, median dose intensity was 20 mg/day. Overall survival by day 28 was 94.1%. Cumulative incidence of clinical improvement of ≥2 points in the ordinal scale was 82.4% (95% confidence interval, 71-93). Clinical improvement was not affected by low-flow versus high-flow oxygen support but was less frequent in patients with PaO2/FiO2 < 200 mmHg. The most frequent adverse events were anemia, urinary tract infections, and thrombocytopenia. Improvement of inflammatory cytokine profile and activated lymphocyte subsets was observed at day 14. In this prospective cohort of aged and high-risk comorbidity patients with severe COVID-19, compassionate-use ruxolitinib was safe and was associated with improvement of pulmonary function and discharge home in 85.3%. Controlled clinical trials are necessary to establish efficacy of ruxolitinib in COVID-19.

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. By echocardiography performed within 24 h from the admission, LV systolic dysfunction was defined as global longitudinal strain (GLS) > -14%; RV systolic dysfunction as Tricuspid Annular Plane Systolic Excursion (TAPSE) < 16 mm. All-cause mortality was assessed at day-7 and day-28 follow-up. Mean values of LV GLS (-12.3 ± 3.4 vs -12.9 ± 3.8%) and TAPSE (1.8 ± 0.7 vs 1.8 ± 0.5 cm, all p = NS) were similar in patients with and in those without shock. LV GLS was significantly worse in LAC + than LAC- patients (- 11.2 ± 3.1 vs - 12.9 ± 3.7%, p = 0.001). 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 aim of the study is to evaluate the prognostic value of early PCSK9 levels in non-intubated septic patients admitted to the emergency department. This report utilized a portion of the data collected in a prospective study, with the aim of identifying reliable biomarkers for an early sepsis diagnosis. In the period November 2011-December 2016, we enrolled 268 patients, admitted to our High-Dependency Unit from the emergency department with a diagnosis of sepsis. Study-related blood samplings were performed at ED-HDU admission (T0), after 6 h (T6) and 24 h (T24). The primary endpoint was in-hospital mortality rate. PCSK9 circulating levels were higher than the normal value (≤ 313 ng/mL): at T0 661 ± 405 ng/mL, at T6 687 ± 417 ng/mL, at T24 718 ± 430 ng/mL. We divided the study population based on T0 quartiles distribution (≤ 370, 370-600, 600-900 and > 900 ng/ml). At T0, patients with normal PCSK9 showed the highest mortality compared to those in higher quartiles (T0: 39%, 20%, 23% and 18%, p = 0.036). By T6, the mortality curve tended to become U-shaped, with the lowest mortality among patients in the intermediate subgroups and an adverse prognosis in the presence of normal or very high levels of PCSK9 (35%, 26%, 18% and 23%, p = 0.235). A Kaplan-Meier analysis showed an increased mortality in patients with T0 and T6 PCSK9 ≤ 313 ng/ml (T0: 55 vs. 80%, p = 0.001; T6: 62 vs. 78%, p = 0.034). In subgroups with increasing levels of PCSK9, we found the best prognosis in the intermediate subgroups and an increased mortality among patients with normal and high values.

Background: In actuality, it is difficult to obtain an early prognostic stratification for patients with acute respiratory failure treated with noninvasive ventilation (NIV). We tested whether an early evaluation through a predictive scoring system could identify subjects at risk of in-hospital mortality or NIV failure., Methods: This was a retrospective study, which included all the subjects with acute respiratory failure who required NIV admitted to an emergency department-high-dependence observation unit between January 2014 and December 2017. The HACOR (heart rate, acidosis [by using pH], consciousness [by using the Glasgow coma scale], oxygenation [by using [Formula: see text]/[Formula: see text]], respiratory rate) score was calculated before the NIV initiation (T0) and after 1 h (T1) and 24 h (T24) of treatment. The primary outcomes were in-hospital mortality and NIV failure, defined as the need for invasive ventilation., Results: The study population included 644 subjects, 463 with hypercapnic respiratory failure and an overall in-hospital mortality of 23%. Thirty-six percent of all the subjects had NIV as the "ceiling" treatment. At all the evaluations, nonsurvivors had a higher mean ± SD HACOR score than did the survivors (T0, 8.2 ± 4.9 vs 6.1 ± 4.0; T1, 6.6 ± 4.8 vs 3.8 ± 3.4; T24, 5.3 ± 4.5 vs 2.0 ± 2.3 [all P < .001]). These data were confirmed after the exclusion of the subjects who underwent NIV as the ceiling treatment (T0, 8.2 ± 4.9 vs 6.1 ± 4.0 [ P = .002]; T1, 6.6 ± 4.8 vs 3.8 ± 3.4; T24, 5.3 ± 4.5 vs 2.0 ± 3.2 [all P < .001]). At T24, an HACOR score > 5 (Relative Risk [RR] 2.39, 95% CI 1.60-3.56) was associated with an increased mortality rate, independent of age and the Sequential Organ Failure Assessment score., Conclusions: Among the subjects treated with NIV for acute respiratory failure, the HACOR score seemed to be a useful tool to identify those at risk of in-hospital mortality., Competing Interests: The authors have no conflict of interest to declare., (Copyright © 2020 by Daedalus Enterprises.)

We evaluated whether in sepsis, right ventricular (RV) systolic dysfunction (RVSD) predicts short-term all-cause mortality, independently to left ventricular (LV) global longitudinal peak systolic strain (GLS). This is a prospective observational study. We enrolled 252 septic patients (40% with shock) between October 2012 and July 2018 among those admitted to High-Dependency Unit. By echocardiography within 24 h from the admission (T1), RVSD was defined as Tricuspid Annular Plane Systolic Excursion (TAPSE) < 16 mm, while left ventricular systolic dysfunction (LVSD) was defined by bi-dimensional speckle-tracking-based global longitudinal peak systolic strain (GLS) > -14%. We assessed all-cause mortality at day-7 and at day-28 from admission. Mortality rate was 14% by day-7 and 26% by day-28 follow-up. RVSD was found in 85 patients (34%), was isolated in 29% (25/85) and coexisted with LVSD in 71% (60/85) patients. LVSD was present in 63% of patients (159/252), and was isolated in 99 patients. Day-7 mortality rate was twofold higher in the presence of RVSD (20% vs 11%), without reaching the statistical significance (p = 0.097). By day-28, mortality rate was as high as 44% with and 23% without RVSD (p = 0.001). In a Cox survival analysis, RVSD predicted higher mortality rate by day-28 follow-up (RR 2.43, 95% CI 1.47-4.00, p = 0.001), independent to shock and in addition to LVSD. In sepsis, RVSD predicted all-cause mortality by day-28 follow-up, independent to LVSD.

To analyze the prognostic value of lactate levels for day-7 and in-hospital mortality, in septic patients with and without shock. In the period November 2011-December 2016, we enrolled 268 patients, admitted to our High-Dependency Unit with a diagnosis of sepsis. Lactate dosage was performed at ED-HDU admission (T0), after 2 h (T2), 6 h (T6) and 24 h (T24); lactate clearance was calculated at T2 and T6 [T2: ((LAC T0-LAC T2/LAC T0)*100)]; T6: [(LAC T0-LAC T6/LAC T0)*100]. The end-points were day-7 and in-hospital mortality. At every evaluation, the lactate level was higher in patients with shock than in those without (T0 3.8 ± 3.8 vs 2.4 ± 2.1; T6 2.9 ± 3.2 vs 1.6 ± 1.1; T24 3.0 ± 4.4 vs 1.4 ± 0.9 meq/L, all p < 0.001). Among patients with shock, an analysis for repeated measures confirmed a more marked lactate level reduction in survivors compared with non-survivors, both by day-7 and in-hospital mortality (p = 0.057 and p = 0.006). A Kaplan-MeIer analysis confirmed a significantly better day-7 survival in patients with T6 (with shock 86% vs 70%; without shock 93% vs 82, all p < 0.05) and T24 (with shock 86% vs 70%; without shock 93% vs 82, all p < 0.05) lactate ≤ 2 meq/L, compared with patients with higher levels. A T6 lactate clearance > 10% was more frequent among in-hospital survivors in the whole study population (57% vs 39%) and in patients with shock (74% vs 46%, all p < 0.05). Higher lactate levels and decreased clearance were associated with an increased short-term and intermediate-term mortality regardless of the presence of shock.

Background: The aim of this study was to assess prognostic stratification in patients admitted in two Italian Emergency-Department High-Dependency Units (ED-HDU)., Methods: From June 2014, to July 2016, we recorded all patients admitted in the ED-HDU of the Careggi University Hospital and the Vittorio Emanuele University Hospital in a standardized database. Charlson Index and SOFA Score were calculated to evaluate comorbidity burden and severity of organ dysfunction. End-points were HDU and in-hospital mortality rate and need of Intensive Care Unit (ICU) transfer., Results: The overall number of patients admitted in the two Units was 3311, 1822 in Florence and 1489 in Catania. HDU mortality rate was 5% (N.=171); compared with survivors, non-survivors showed a higher SOFA Score (10.0±4.2 vs. 3.5±2.9, P<0.001) and a higher number of organ dysfunctions (1.6±0.9 vs. 0.6±0.8, P<0.001). All patients with a SOFA Score in the first and second quartile survived HDU admission (only two non-survivors among patients in the second quartile), while mortality was disproportionally high in the group with a score value in the fourth quartile (0%, 0.2%, 3% and 14%, P<0.001). Presence and number of organ failure, as well as SOFA Score (5.6±4.0 vs. 3.4±2.8, P<0.001), were significantly higher in patients transferred to ICU than in those admitted in an ordinary ward or discharged. A higher SOFA Score (RR 1.55, 95% CI: 1.47-1.63, P<0.001) was associated with an increased HDU mortality, independent of age and Charlson Index., Conclusions: SOFA Score showed a good discrimination ability for both HDU - mortality and indication to increase the level of care.

To evaluate if the assessment of coagulation abnormalities at ED admission could improve prognostic assessment of septic patients. This report utilizes a portion of the data collected in a prospective study, with the aim to identify reliable biomarkers for an early sepsis diagnosis. In the period November 2011-December 2016, we enrolled 268 patients, admitted to our High-Dependency Unit with a diagnosis severe sepsis/septic shock. Study-related blood samplings were performed at ED-HDU admission (T0), after 6 h (T6) and 24 h (T24): D-dimer, thrombin-antithrombin complex (TAT) and prothrombin fragment F1 + 2 levels were analyzed. The primary end-points were day-7 and in-hospital mortality. Day-7 mortality rate was 16%. D-dimer (T0: 4661 ± 4562 µg/ml vs 3190 ± 7188 µg/ml; T6: 4498 ± 4931 µg/ml vs 2822 ± 5623 µg/ml; T24 2905 ± 2823 µg/ml vs 2465 ± 4988 µg/ml, all p < 0.05) and TAT levels (T0 29 ± 45 vs 22 ± 83; T6 21 ± 22 vs 15 ± 35; T24 16 ± 19 vs 13 ± 30, all p < 0.05) were higher among non-survivors compared to survivors. We defined an abnormal coagulation activation (COAG+) as D-dimer > 500 µg/ml and TAT > 8 ng/ml (for both, twice the upper normal value). Compared to COAG-, COAG+ patients showed higher lactate levels at the earliest evaluations (T0: 3.3 ± 2.7 vs 2.5 ± 2.3, p = 0.041; T6: 2.8 ± 3.4 vs 1.8 ± 1.6, p = 0.015); SOFA score was higher after 24 h (T24: 6.7 ± 3.1 vs 5.4 ± 2.9, p = 0.008). At T0, COAG+ patients showed a higher day-7 mortality rate (HR 2.64; 95% CI 1.14-6.11, p = 0.023), after adjustment for SOFA score and lactate level. Presence of abnormal coagulation at ED admission shows an independent association with an increased short-term mortality rate.

We evaluated the ability of a stress-test (Str-T) to improve the risk stratification based on prognostic scores in patients presenting to the ED with chest pain. Between 2008, June and 2013, December, 1082 patients with chest pain were evaluated with an imaging Str-T. With a retrospective analysis, patients were stratified according to: (1) Florence Prediction Rule as low (0-1, LR-FPR), intermediate (2-4, IR-FPR), high risk (5-6, HR-FPR), respectively, 26, 50 and 24% of patients; (2) HEART score as LR-HEART, (0-3) and HR-HEART (≥4), respectively, 36 and 64%; (3) likelihood of CAD according to NICE guidelines, 10-29% LR-NICE, 30-60% IR-NICE and > 60% HR-NICE, respectively, 12, 18 and 70%. Scores' diagnostic performance was calculated with Str-T as reference. One-month follow-up by a phone call was performed, to investigate the occurrence of new cardiovascular events. In LR and HR patients, FPR and NICE score showed sensitivity 66 vs 93%, specificity 59 vs 19% (both p < 0.001), Positive Predictive Value (PPV) 36 vs 31%, Negative Predictive Value (NPV) 83 vs 87%. Among LR-HEART patients, Str-T was positive for inducible ischemia in 53 (14%) patients and 12 (4%) of them underwent a percutaneous coronary revascularization. The Str-T was negative for inducible ischemia in 760 (70%) patients, positive in 272 (25%), inconclusive in 50 (5%); among patients in the LR and IR subgroups, incidence of CAD (1.3 and 1.6%) and the cumulative incidence of significant events at 1-month follow-up (both 1%) was very low Str-T improved prognostic scores' diagnostic performance in LR- and HR-subgroups.

Background: Acute dyspnea is a common symptom in the ED. The standard approach to dyspnea often relies on radiologic and laboratory results, causing excessive delay before adequate therapy is started. Use of an integrated point-of-care ultrasonography (PoCUS) approach can shorten the time needed to formulate a diagnosis, while maintaining an acceptable safety profile., Methods: Consecutive adult patients presenting with dyspnea and admitted after ED evaluation were prospectively enrolled. The gold standard was the final diagnosis assessed by two expert reviewers. Two physicians independently evaluated the patient; a sonographer performed an ultrasound evaluation of the lung, heart, and inferior vena cava, while the treating physician requested traditional tests as needed. Time needed to formulate the ultrasound and the ED diagnoses was recorded and compared. Accuracy and concordance of the ultrasound and the ED diagnoses were calculated., Results: A total of 2,683 patients were enrolled. The average time needed to formulate the ultrasound diagnosis was significantly lower than that required for ED diagnosis (24 ± 10 min vs 186 ± 72 min; P = .025). The ultrasound and the ED diagnoses showed good overall concordance (κ = 0.71). There were no statistically significant differences in the accuracy of PoCUS and the standard ED evaluation for the diagnosis of acute coronary syndrome, pneumonia, pleural effusion, pericardial effusion, pneumothorax, and dyspnea from other causes. PoCUS was significantly more sensitive for the diagnosis of heart failure, whereas a standard ED evaluation performed better in the diagnosis of COPD/asthma and pulmonary embolism., Conclusions: PoCUS represents a feasible and reliable diagnostic approach to the patient with dyspnea, allowing a reduction in time to diagnosis. This protocol could help to stratify patients who should undergo a more detailed evaluation., (Copyright © 2017 American College of Chest Physicians. Published by Elsevier Inc. All rights reserved.)

The aim of this study was to investigate the utility of repeat head CT in a large population of patients with non-isolated blunt mild head trauma (MTBI), especially in the presence of intracranial injury. This is a study of a cohort of 478 non-isolated MTBI patients admitted to the High Dependency Unit of the Emergency Department of the University-Hospital of Florence from July 2008 to December 2013. Results of initial and subsequent head CT scans, and indications for repeat head CT scan (routine vs. neurologic change) were recorded. The study population was divided into two subgroups: 28 (6 %) patients with neurological change or persistently reduced GCS (group GCS-) and 450 (94 %) patients with normal or improving GCS (group GCS+). After 6 months from the event, a telephone interview using SF12 questionnaire was conducted. Among GCS- patients, the admission CT scan showed intracranial lesions (ICI) in 16 (57 %) patients; only two patients had a TBI-related neurosurgical intervention. Among GCS+ patients, the first CT scan showed an ICI in 133 patients; in a significant proportion of patients with ICI at the first CT scan, the injury worsened (40/133, 30 %, p < 0.0001). However, no GCS+ patient had any neurosurgical intervention. We observed a significant reduction in both MCS and PCS scores after the injury compared with the previous period. The number of repeat CT scan was high in patients who presented ICI at the first CT scan; however, no patient with ICI and normal or improving GCS score needed a neurosurgical intervention.

Background: The aim of this study was to compare the feasibility of dobutamine stress echocardiography (DSE) and exercise stress test (EST) between patients in different age groups and to evaluate their proportional prognostic value in a population with established coronary artery disease (CAD)., Methods: The study sample included 323 subjects, subdivided in group 1 (G1), comprising 246 patients aged <75 years, and group 2 (G2), with 77 subjects aged >or=75 years. DSE and EST were performed before enrollment in a cardiac rehabilitation program; for prognostic assessment, end points were all-cause mortality and hard cardiac events (cardiac death or nonfatal myocardial infarction)., Results: During DSE, G2 patients showed worse wall motion score index (WMSI), but the test was stopped for complications in a comparable proportion of cases (54 G1 and 19 G2 patients, P = NS). EST was inconclusive in similarly high proportion of patients in both groups (76% in G1 vs. 84% in G2, P = NS); G2 patients reached a significantly lower total workload (6 +/- 1.6 METs in G1 vs. 5 +/- 1.2 METs in G2, P < 0.001). At multivariate analysis, a lower peak exercise capacity (HR 0.566, CI 0.351-0.914, P = 0.020) was associated with higher mortality, while a high-dose WMSI >2 (HR 5.123, CI 1.559-16.833, P = 0.007), viability (HR 3.354, CI 1.162-9.678, P = 0.025), and nonprescription of beta-blockers (HR 0.328, CI 0.114-0.945, P = 0.039) predicted hard cardiac events., Conclusion: In patients with known CAD, EST and DSE maintain a significant prognostic role in terms of peak exercise capacity for EST and of presence of viability and an extensive wall motion abnormalities at peak DSE.
