The background of this study is to assess the accuracy of lung ultrasound (LUS) to diagnose interstitial lung disease (ILD) in Sjögren's syndrome (Sjs), in patients who have any alterations in pulmonary function tests (PFT) or respiratory symptoms. LUS was correlated with chest tomography (hrCT), considering it as the imaging gold standard technique to diagnose ILD. This is a pilot, multicenter, cross-sectional, and consecutive-case study. ⋯ The correlation of Pearson is r = 0.84 (p < 0.001). To check the accuracy of LUS to diagnose ILD, a completely bilateral criterion of yes/no for interstitial pattern was chosen, AUC reaches significance, 0.94 (0.07) (95% CI 0.81-1.0, p = 0.014). LUS reaches an excellent correlation to hrCT in Sjs affected with ILD, and might be a useful technique in daily clinical practice for the assessment of pulmonary disease in the sicca syndrome.

Sepsis is a rapidly evolving disease with a high mortality rate. The early identification of sepsis and the implementation of early evidence-based therapies have been recognized to improve outcome and decrease sepsis-related mortality. The aim of this study was to compare the accuracy of the standard diagnostic work-up of septic patients with an integrated approach using early point of care ultrasound (POCUS) to identify the source of infection and to speed up the time to diagnosis. ⋯ Instead the septic source was identified within 1 h in only 21.9 % and within 3 h in 52.8 % with a standard work-up. POCUS-implemented diagnosis is an effective and reliable tool for the identification of septic source, and it is superior to the initial clinical evaluation alone. It is likely that a wider use of POCUS in an emergency setting will allow a faster diagnosis of the septic source, leading to more appropriate and prompt antimicrobial therapy and source control strategies.

Utility of FVC/DLCO ratio to stratify the risk of mortality in unselected subjects with pulmonary hypertension.
In patients with systemic sclerosis, a ratio between forced vital capacity (FVC) and diffusing capacity of carbon monoxide (DLCO, FCV%/DLCO%) >1.5 might be a predictor of pulmonary hypertension (PH). The aim of this study is, therefore, to evaluate whether this index can be used in patients with PH, regardless of etiology. 83 consecutive outpatients with suspected PH at non-invasive work-up underwent spirometry and DLCO test before right heart catheterization (RHC); FVC%/DLCO% ratio was then calculated and compared with mean pulmonary-artery-pressure (mPAP) and mortality at 5-year follow-up. Significant correlations between FVC%/DLCO% and PAsP and mPAP levels were found (p < 0.05). ⋯ Poorer survival rates are observed at follow-up with higher FVC%/DLCO% values (0% for <1, 17.4% for 1-3, 33.3% for >3, p < 0.05), when comparing subjects with either increased PAsP and FVC%/DLCO% values or both with those with lower (log-rank p < 0.05). Even in subjects with mPAP at RHC >25 mmHg, increased FVC%/DLCO% values predicted a worse outcome (p < 0.05). FVC%/DLCO% values are related to mPAP in subjects with suspected PH, and may further stratify the risk of mortality in addition to PAP.

The HEART score with high-sensitive troponin T at presentation: ruling out patients with chest pain in the emergency room.
The HEART score is a simple scoring system, ranging from 0 to 10, specifically developed for risk stratification of patients with undifferentiated chest pain. It has been validated for the conventional troponin, but not for high-sensitive troponin. We assess a modified version of the HEART score using a single high-sensitivity troponin T dosage at presentation, regardless of symptom duration, and with different ECG criteria to evaluate if the patients with a low HEART score could be safely discharged early. ⋯ None of the 512 (37.2 %) patients with a low HEART score had an event within 180 days. The difference between the cumulative incidences of events in the three HEART score groups was statistically significant (P < 0.0001). We demonstrate that it might be possible to safely discharge Emergency Department chest pain patients with a low modified HEART score after an initial determination of high-sensitive troponin T, without a prolonged observation period or an additional cardiac testing.

We sought to compare length-of-stay (LOS), total hospital costs, and readmissions among pulmonary embolism (PE) patients treated with rivaroxaban versus parenterally bridged warfarin. We identified adult PE (primary diagnostic code = 415.1x) patients in the Premier Database (11/2012-9/2015), and included those with ≥1 PE diagnostic test on days 0-2. Rivaroxaban users (allowing ≤2 days of prior parenteral therapy) were 1:1 propensity score matched to patients parenterally bridged to warfarin. ⋯ Results were similar in low-risk patients (0.2-1.0 day and $251-$1751 reductions in LOS and costs, respectively, p ≤ 0.01 for all). In patients with PE, rivaroxaban was associated with reduced LOS and costs, without increased risk of readmission versus parenterally bridged warfarin. Similar results were observed in low-risk PE patients.
