Septal Perforation Quality of Life questionnaire (SEPEQOL): validation of a new instrument to assess patients undergoing endoscopic repair of a nasal septal perforation.
No full text20.500.12530/87854Nasoseptal perforations (NSP) are a clinically heterogeneous group of disorders with a wide range of available treatments. Patient-reported outcome measures (PROMs) can provide valuable insights for assessing clinical and surgical outcomes. This study aims to develop and validate a novel-specific questionnaire for patients with NSP. A multi-centre prospective observational study was conducted at two tertiary referral hospitals. "Septal Perforation Quality of Life" (SEPEQOL) was developed by a committee of experts. The psychometric properties, including reproducibility, reliability, validity, and responsiveness, were assessed. The study included 96 symptomatic NSP patients and 30 healthy controls. SEPEQOL internal consistency was satisfactory [Cronbach´s α = 0.7843; 95% confidence interval (CI), 0.702-0.856]. Test-retest reliability was excellent, demonstrated by the absolute intraclass correlation (ICC = 0.974; 95% CI, 0.935-0.989, P-value SEPEQOL is reliable, consistent, valid, and sensitive to change over time. SEPEQOL assesses the impact of health-related quality of life on NSP and its management in clinical practice. Moreover, it is easy to apply in clinical settings with minimal burden
The Challenge of Treating Infections Caused by Metallo-β-Lactamase-Producing Gram-Negative Bacteria: A Narrative Review.
No full text20.500.12530/87913Gram-negative multidrug-resistant (MDR) bacteria, including Enterobacterales, Acinetobacter baumannii, and Pseudomonas aeruginosa, pose a significant challenge in clinical practice. Infections caused by metallo-β-lactamase (MBL)-producing Gram-negative organisms, in particular, require careful consideration due to their complexity and varied prevalence, given that the microbiological diagnosis of these pathogens is intricate and compounded by challenges in assessing the efficacy of anti-MBL antimicrobials. We discuss both established and new approaches in the treatment of MBL-producing Gram-negative infections, focusing on 3 strategies: colistin; the recently approved combination of aztreonam with avibactam (or with ceftazidime/avibactam); and cefiderocol. Despite its significant activity against various Gram-negative pathogens, the efficacy of colistin is limited by resistance mechanisms, while nephrotoxicity and acute renal injury call for careful dosing and monitoring in clinical practice. Aztreonam combined with avibactam (or with avibactam/ceftazidime if aztreonam plus avibactam is not available) exhibits potent activity against MBL-producing Gram-negative pathogens. Cefiderocol in monotherapy is effective against a wide range of multidrug-resistant organisms, including MBL producers, and favorable clinical outcomes have been observed in various clinical trials and case series. After examining scientific evidence in the management of infections caused by MBL-producing Gram-negative bacteria, we have developed a comprehensive clinical algorithm to guide therapeutic decision making. We recommend reserving colistin as a last-resort option for MDR Gram-negative infections. Cefiderocol and aztreonam/avibactam represent favorable options against MBL-producing pathogens. In the case of P. aeruginosa with MBL-producing enzymes and with difficult-to-treat resistance, cefiderocol is the preferred option. Further research is needed to optimize treatment strategies and minimize resistance
Sodium-glucose cotransporter 2 inhibition in primary and secondary glomerulonephritis.
No full text20.500.12530/87852The role of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in the management glomerular/systemic autoimmune diseases with proteinuria in real-world clinical settings is unclear. This is a retrospective, observational, international cohort study. Adult patients with biopsy-proven glomerular diseases were included. The main outcome was the percentage reduction in 24-h proteinuria from SGLT2i initiation to 3, 6, 9 and 12 months. Secondary outcomes included percentage change in estimated glomerular filtration rate (eGFR), proteinuria reduction by type of disease and reduction of proteinuria ≥30% from SGLT2i initiation. Four-hundred and ninety-three patients with a median age of 55 years and background therapy with renin-angiotensin system blockers were included. Proteinuria from baseline changed by -35%, -41%, -45% and -48% at 3, 6, 9 and 12 months after SGLT2i initiation, while eGFR changed by -6%, -3%, -8% and -10.5% at 3, 6, 9 and 12 months, respectively. Results were similar irrespective of the underlying disease. A correlation was found between body mass index (BMI) and percentage proteinuria reduction at last follow-up. By mixed-effects logistic regression model, serum albumin at SGLT2i initiation emerged as a predictor of ≥30% proteinuria reduction (odds ratio for albumin The use of SGLT2i was associated with a significant reduction of proteinuria. This percentage change is greater in patients with higher BMI. Higher serum albumin at SGLT2i onset is associated with higher probability of achieving a ≥30% proteinuria reduction

Tricuspid valve disease and cardiac implantable electronic devices.
No full text20.500.12530/87854The role of cardiac implantable electronic device (CIED)-related tricuspid regurgitation (TR) is increasingly recognized as an independent clinical entity. Hence, interventional TR treatment options continuously evolve, surgical risk assessment and peri-operative care improve the management of CIED-related TR, and the role of lead extraction is of high interest. Furthermore, novel surgical and interventional tricuspid valve treatment options are increasingly applied to patients suffering from TR associated with or related to CIEDs. This multidisciplinary review article developed with electrophysiologists, interventional cardiologists, imaging specialists, and cardiac surgeons aims to give an overview of the mechanisms of disease, diagnostics, and proposes treatment algorithms of patients suffering from TR associated with CIED lead(s) or leadless pacemakers
High-Sensitivity vs Conventional Troponin Cutoffs for Risk Stratification in Patients With Acute Pulmonary Embolism.
No full text20.500.12530/87854High-sensitivity troponin tests can detect even milder cardiac troponin elevations in plasma, beyond the threshold of conventional troponin tests. Whether detection of low-grade cardiac troponin elevation is associated with outcomes of patients with hemodynamically stable pulmonary embolism (PE) and helps with risk stratification is unknown. To determine the association between high-sensitivity cardiac troponin I (hs-cTnI) compared with conventional cardiac troponin I (cTnI) and PE risk designations according to the European Society of Cardiology (ESC) 2019 classification scheme and clinical outcomes in patients with hemodynamically stable PE. This is a post hoc analysis of data from the prospective Prognostic Value of Computed Tomography (PROTECT) multicenter cohort study enrolling patients from 12 hospital emergency departments in Spain. In this analysis, cTnI and hs-cTnI were compared with respect to ESC risk designation, and the association between troponin values and a complicated course after PE diagnosis was evaluated. Of 848 patients enrolled in PROTECT, 834 (98.3%) had hsTnI and cTnI values available and were included in the present analysis. Data were analyzed from May to December 2022. Troponin blood testing with cTnI (threshold of >0.05 ng/mL) vs hs-cTnI (threshold of >0.029 ng/mL) assays at the time of PE diagnosis. Complicated course, defined as hemodynamic collapse, recurrent PE, or all-cause death, within 30 days after PE. Of 834 patients (mean [SEM] age, 67.5 [0.6] years; 424 [50.8%] female), 139 (16.7%) had elevated cTnI and 264 (31.7%) elevated hs-TnI, respectively. During follow-up, 62 patients (7.4%; 95% CI, 5.7-9.4) had a complicated course. Analyzing troponin elevation as a binary variable, elevated cTnI (odds ratio [OR], 2.84; 95% CI, 1.62-4.98) but not hs-cTnI (OR, 1.12; 95% CI, 0.65-1.93) was associated with increased odds of a complicated course. Of 125 patients who had elevated hs-cTnI but normal cTnI, none (0; 95% CI, 0.0-2.9) developed a complicated course. Using the 2019 ESC risk stratification scheme, hs-TnI classified fewer patients as low risk compared with cTnI. Among 78 patients designated as ESC low risk when using cTnI but not with hsTnI, none (0; 95% CI, 0.0-4.6) had a complicated course. In this study of patients with hemodynamically stable PE, hs-cTnI identified modest elevations in cardiac troponin levels. However, the results did not provide additive clinical value compared with cTnI. These findings suggest that use of hs-cTnI may result in overestimation of the risk in patients with stable PE

European Society of Organ Transplantation (ESOT) Consensus Statement on Machine Perfusion in Cardiothoracic Transplant
No full textThe machine perfusion (MP) of transplantable grafts has emerged as an upcoming field in Cardiothoracic (CT) transplantation during the last decade. This technology carries the potential to assess, preserve, and even recondition thoracic grafts before transplantation, so it is a possible game-changer in the field. This technology field has reached a critical turning point, with a growing number of publications coming predominantly from a few leading institutions, but still need solid scientific evidence. Due to the increasing need to expand the donor pool, especially in Europe, where the donor age is steeply increased, a consensus has been established to address the growing need and knowledge of machine perfusion in cardiothoracic transplantation, targeting the unmet scientific need in this growing field but also, priorities for development, and regional differences in utilization rates and organizational issues. To address MP in CT, the European Society of Organ Transplantation (ESOT) convened a dedicated Working group comprised of experts in CT to review literature about MP to develop guidelines that were subsequently discussed and voted on during the Consensus Conference that took place in person in Prague during the TLJ 3.0 in November 2022. The findings and recommendations of the Cardiothoracic Working Group on MP are presented in this article
Intermediate-effect size p.Arg637Gln in FHOD3 increases risk of HCM and is associated with an aggressive phenotype in homozygous carriers.
No full text20.500.12530/87849Formin homology 2 domain-containing 3 (FHOD3) gene has emerged as one of the main non-sarcomeric genes associated with hypertrophic cardiomyopathy (HCM), but no cases of biallelic variants associated with disease have been described to date. From 2014 until 2021, FHOD3 was evaluated in our center by next-generation sequencing in 22 806 consecutive unrelated probands. The p.Arg637Gln variant in FHOD3 was enriched in our HCM cohort (284 of 9668 probands; 2.94%) compared with internal controls (64 of 11 480; 0.59%) and gnomAD controls (373 of 64 409; 0.58%), with ORs of 5.40 (95% CI: 4.11 to 7.09) and 5.19 (95% CI: 4.44 to 6.07). The variant affects a highly conserved residue localised in a supercoiled alpha helix considered a clustering site for HCM variants, and in heterozygosis can act as a predisposing factor (intermediate-effect variant) for HCM, with an estimated penetrance of around 1%. Additionally, seven homozygous carriers of p.Arg637Gln in FHOD3 were identified. All but one (unaffected) showed an early presentation and a severe HCM phenotype. All this information suggest that p.Arg637Gln variant in FHOD3 is a low-penetrant variant, with an intermediate effect, that contributes to the development of HCM in simple heterozygosis, being associated with a more severe phenotype in homozygous carriers
