RESUMEN
Introduction: Ureteroscopic lithotripsy (URSL) is an approved, minimally invasive, low-risk procedure for urolithiasis treatment. However, some patients may develop urinary tract infection (UTI) post-procedure, eventually leading to urosepsis. Determining the predictors of infection after URSL would help identify patients at a high risk of urosepsis, thereby enabling the early implementation of effective treatment. Therefore, we aimed to establish the incidence and predictors of urosepsis after URSL. Material and methods: We assessed 231 patients who underwent URSL using a holmium laser. The incidence of urosepsis during the 30-day post-treatment period was analysed, and potential predictors of urosepsis, including patient characteristics and individual clinical factors, were examined. Results: Statistical analysis revealed that 16.88% of patients had a confirmed positive urine culture before the procedure. Post-procedure urosepsis occurred in 4.76% of patients. Univariable analysis revealed that 3 factors were significantly associated with the risk of postoperative urosepsis: double-J stent insertion before URSL, pre-operative positive urine culture, and MDR pathogen found preoperatively. In multivariable analysis, only positive urine culture remained significantly associated with the risk of urosepsis after URSL. Conclusions: Patients with positive urine culture before URSL are at significantly higher risk of urosepsis in the postoperative period. Hence, urine culture should be routinely performed before planned endoscopic urolithiasis treatment.
RESUMEN
BACKGROUND: The Pulmonary Embolism Severity Index (PESI) is a validated tool to predict 30-day all-cause mortality in patients with acute pulmonary embolism (PE) but includes only clinical variables. AIMS: We aimed to determine the effectiveness of PESI extended with an echocardiographic parameter. METHODS: This cross-sectional observational study included consecutive patients with acute PE diagnosed with computed tomography pulmonary angiography. RESULTS: Of 117 subjects (57 men, 48.7%), at a median age of 69 (59-80) years, 16 patients died during the 30-day follow-up. Six modified models of PESI with an additional single echocardiographic parameter were created, which increased the predictive value of PESI (area under the curve [AUC] 0.8608): tricuspid annular plane systolic excursion (TAPSE) <18 mm, right ventricular (RV) free wall longitudinal strain (RVFWLS) >-23%, 60/60 sign, RV global longitudinal strain (RVGLS) >-16%, pulmonary ejection acceleration time (AcT) <67 ms, and thrombus in right heart cavities (AUC 0.8657 to 0.8976, respectively, all markers P <0.001). TAPSE, AcT, RVFWLS, and RVGLS showed significant correlations with the PESI score, but not a thrombus in the right heart cavity or the 60/60 sign. As PESI adjuncts, they independently predicted fatal outcomes: thrombus with hazard ratio (HR) 10.04 (95% confidence interval [CI], 2.81-37.12; P <0.001) and the 60/60 sign with HR 4.07 (95% CI, 1.27-12.81; P <0.001). CONCLUSIONS: The quantitative echocardiographic parameters of RV systolic function and pulmonary artery blood flow are associated with the PESI score and thus increase its predictive value to a limited extent. PE- specific findings: a thrombus in the right heart cavity and the 60/60 sign are effective adjuncts to the PESI score.

INTRODUCTION: Tyrosine kinase inhibitors (TKIs) revolutionized treatment of chronic myeloid leukemia (CML), but are endowed with negative effects on endothelial function. OBJECTIVES: We aimed to characterize endothelial function in patients with CML treated with various TKIs. PATIENTS AND METHODS: A total of 48 patients diagnosed with chronicphase CML treated with TKIs, such as imatinib, bosutinib, nilotinib, ponatinib, and asciminib were included. Endothelial function was assessed in the brachial artery and microcirculation based on flowmediated dilation (FMD), reactive hyperemia peripheral arterial tonometry (RHPAT) and flowmediated skin fluorescence (FMSF). RESULTS: Reactive hyperemia index, FMD, reactive hyperemia response (RHR), normoxia oscillatory index, and hyperemic response index did not differentiate between the group of patients with low / moderate risk in the Systematic Coronary Risk Estimation 2 (SCORE2), SCORE2Older Persons (SCORE2OP), and those with high / very high risk scores. Among the patients with low / intermediate risk based on the SCORE2 algorithm, some had lower (below the first quartile) values of the endothelial parameters, reflecting impaired endothelial function, as compared with the high / very high risk patient population. Lower values of the endothelial function parameters were associated with overall longterm treatment with TKIs or ponatinib. Importantly, endothelial function assessed by FMSF (RHR) negatively correlated with total duration of TKI treatment, also after adjustment for age. CONCLUSIONS: Endothelial function in CML patients treated with TKIs was not related to cardiovascular risk based on SCORE2/SCORE2OP algorithms but correlated with CMLspecific factors, including duration of TKI treatment. FMSFbased assessment of skin microcirculation was a sensitive method for detecting the vascular effects of TKIs.
