Prediction of right ventricular dysfunction from radiographic estimates of right descending pulmonary artery in hemodynamically stable pulmonary embolism patients

Background: The evaluation of right ventricular (RV) dysfunction by echocardiography isone of the most important established determinants of the prognosis of acute pulmonary embolism.The aim of the study was to investigate possible association between diameter of rightdescending pulmonary artery on chest X-rays and RV dysfunction by echocardiography inhemodynamically stable pulmonary embolism patients.Methods: Eighty-nine patients with the diagnosis of hemodynamically stable pulmonaryembolism were included.Results: The frequency of RV dysfunction was signifi cantly higher in patients with anenlarged right descending pulmonary artery on chest X-rays (p = 0.001). There wasa signifi cant positive correlation between the diameter of the right descending pulmonary arteryon postero-anterior chest X-rays and the diameter of the RV (r = 0.469; p = 0.002). Diameterof right descending pulmonary artery on chest X-rays was also found as a signifi cant predictorof RV dysfunction besides the troponin-T levels and systolic pulmonary arterial pressure (p < 0.05).Conclusions: Diameter of right descending pulmonary artery on chest X-rays may provideinformation about the risk for pulmonary embolism patients and may be used as a prognosticradiological parameter for the appropriate management of acute pulmonary embolism

Agreement between quantiferon-TB gold test and tuberculin skin test in the identification of latent tuberculosis infection in patients with rheumatoid arthritis and ankylosing spondylitis

ABSTRACT. Objective. To compare the Quantiferon-TB Gold test (QTF-G) with the tuberculin skin test (TST) for the detection of latent tuberculosis infection (LTBI) among patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS), with reevaluation of the patients treated with tumor necrosis factor-α (TNF-α) antagonists in the followup. Methods. The study involved 140 consecutive patients, 82 with RA and 58 with AS. Thirty patients were evaluated with QTF-G for detection of LTBI before and after 6 months of TNF-α antagonist treatment. QTF-G was also performed on 49 healthy controls. QTF-G results were recorded as positive, negative, or indeterminate. A positive TST was defined as ≥ 5 mm for RA and AS. Results. The percentages of positive QTF-G were comparable in RA and AS (37% vs 32%). The rate of positive QTF-G in healthy controls (29%) was also similar to RA and AS. In contrast to QTF-G results, a high rate of TST positivity was observed in AS compared to RA (82% vs 55%; p = 0.02). The total agreement between QTF-G and TST was observed to be 61% (κ = 0.29) in the whole group, 70% (κ = 0.42) in RA, and 49% (κ = 0.14) in AS. After 6 months of treatment with TNF-α antagonists, a high rate of QTF-G change was observed in patients with indeterminate results (23% vs 3%; p = 0.03)

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
