The aim of this study was to determine the incidence of transoesophageal echocardiography (TOE)-related adverse events (AEs) during structural heart disease (SHD) interventions and to identify potential risk factors.

We retrospectively analysed 898 consecutive patients undergoing TOE-guided SHD interventions under procedural sedation. TOE-related AEs were classified as bleeding complications, mechanical lesions, conversion to general anaesthesia with intubation, and the occurrence of pneumonia. A follow-up was conducted up to 3 months after the intervention. TOE-related AEs were observed in 5.3% of the patients (n = 48). The highest rate of AEs was observed in the percutaneous mitral valve repair (PMVR) group with 8.2% (n = 32), whereas 4.8% (n = 11) of the patients in the left atrial appendage group and 1.8% (n = 5) in the patent foramen ovale/atrial septal defect group developed a TOE-related AE (P = 0.001). The most frequent AE was pneumonia with an incidence of 2.6% (n = 26) in the total cohort. Bleedociated with the occurrence of a TOE-related AE.
We sought to examine management and outcomes of (Stanford) type A aortic dissection (TAAAD) in patients aged >70 years.

All patients with TAAAD enrolled in the International Registry of Acute Aortic Dissection database (1996-2018) were studied (n = 5553). Patients were stratified by age and therapeutic strategy. Outcomes for octogenarians were compared with those for septuagenarians. Variables associated with in-hospital mortality were identified by multivariable logistic regression.

In-hospital mortality for all patients (all ages) was 19.7% (1167 deaths), 16.1% after surgical intervention vs 52.1% for medical management (P < 0.001). Of the study population, 1281 patients (21.6%) were aged 71-80 years and 475 (8.0%) were >80 years. Fewer octogenarians underwent surgery versus septuagenarians (68.1% vs 85.9%, P < 0.001). Overall mortality was higher for octogenarians versus septuagenarians (32.0% vs 25.6%, P = 0.008); however, surgical mortality was similar (25.1% vs 21.7%, P = 0.205). Postoperative complications were comparable between surgically managed cohorts, although reoperation for bleeding was more common in septuagenarians (8.1% vs 3.2%, P = 0.033). Kaplan-Meier 5-year survival was significantly superior after surgical repair in all age groups, including septuagenarians (57.0% vs 13.7%, P < 0.001) and octogenarians (35.5% vs 22.6%, P < 0.001).

When compared with septuagenarians, a smaller percentage of octogenarians undergo surgical repair for TAAAD, even though postoperative outcomes are similar. Age alone should not preclude consideration for surgery in appropriately selected patients with TAAAD.

This study explores the current availability of and demand for decentralization of services for four high-priority conditions insulin-dependent diabetes, heart failure, sickle cell disease, and chronic pain. Ministry of Health NCD Programme Managers from across Africa (N = 47) were invited to participate in an online survey. Respondents were asked to report the status of clinical care across the health system. A care package including diagnostics and treatment was described for each condition. Respondents were asked whether the described services are currently available at primary, secondary and tertiary levels, and whether making the service generally available at that level is expected to be a priority in the coming 5 years. Thirty-seven (79%) countries responded. Countries reported widespread gaps in service availability at all levels. We found that just under half (49%) of respondents report that sehronic NCDs.
Aortic wall shear stress (WSS) distributions in bicuspid aortic valve (BAV) patients have been associated with aortic dilatation, but prospective, longitudinal data are missing. This study assessed differences in aortic WSS distributions between BAV patients and healthy controls and determined the association of WSS with aortic growth in patients.

Sixty subjects underwent four-dimensional (4D) flow cardiovascular magnetic resonance of the thoracic aorta (32 BAV patients and 28 healthy controls). Peak velocity, pulse wave velocity, aortic distensibility, peak systolic WSS (magnitude, axial, and circumferential), and WSS angle were assessed. WSS angle is defined as the angle between the WSSmagnitude and WSSaxial component. In BAV patients, three-year computed tomography angiography-based aortic volumetric growth was determined in the proximal and entire ascending aorta. WSSaxial was significantly lower in BAV patients compared with controls (0.93 vs. 0.72 Pa, P = 0.047) and WSScircumferential and WSS angle dilation.Luminal breast cancer (BrCa) has a favorable prognosis compared with other tumor subtypes. However, with time, tumors may evolve and lead to disease progression; thus, there is a great interest in unraveling the mechanisms that drive tumor metastasis and endocrine resistance. In this review, we focus on one of the many pathways that have been involved in tumor progression, the fibroblast growth factor/fibroblast growth factor receptor (FGFR) axis. We emphasize in data obtained from in vivo experimental models that we believe that in luminal BrCa, tumor growth relies in a crosstalk with the stromal tissue. We revisited the studies that illustrate the interaction between hormone receptors and FGFR. We also highlight the most frequent alterations found in BrCa cell lines and provide a short review on the trials that use FGFR inhibitors in combination with endocrine therapies. Analysis of these data suggests there are many players involved in this pathway that might be also targeted to decrease FGF signaling, in addition to specific FGFR inhibitors that may be exploited to increase their efficacy.
Rapid quantification of ADAMTS13 activity in plasma is essential for establishing a diagnosis of thrombotic thrombocytopenic purpura (TTP); a rare, but potentially lethal disorder. The current methods for quantitating ADAMTS13 activity are manual and only available at specialized laboratories, which often results in initiation of specific treatments long before a diagnosis of TTP is established.

We compared the performance of the HemosIL, a novel and rapid automated method, and the current standard FRET (fluorescence resonance energy transfer) method in quantitating ADAMTS13 activity using 706 consecutive plasma samples collected over a period of 14 years. The clinical accuracy of both methods was further examined using 212 diagnostic samples.

The correlation between the FRET and HemosIL methods in all 706 samples and in the 212 diagnostic samples was excellent (Pearson's r of 0.919 and 0.912, respectively). Both methods displayed a high degree of clinical accuracy using the current cutoff of ADAMTS13 activity <0.10 kIU/L (<10%) as diagnostic for TTP the area under the curve (AUC) was 97.7% for the FRET method and 99.5% for the HemosIL method. When applying a lower cutoff (ADAMTS13 activity <0.05 kIU/L or <5%), the diagnostic accuracy of the HemosIL method increased further (AUC = 99.7%).

A novel, rapid method for ADAMTS13 quantification is comparable to the more laborious FRET method in patients with possible TTP. A rapid analysis available in the acute setting assessing patients with possible TTP allows for improved care and optimized treatment of a life-threatening condition.

The clinical usefulness of historical concentrations of high-sensitivity cardiac troponin T (hs-cTnT) is unknown. This study investigated the ability to rule out myocardial infarction (MI) with the use of historical hs-cTnT concentrations among patients with chest pain in the emergency department (ED).

The derivation cohort consisted of patients presenting with chest pain to nine different EDs (n = 60 071), where we included those with ≥1 hs-cTnT analysed at the index visit and ≥1 hs-cTnT results prior to the visit. We developed an algorithm to rule out MI within 30 days with a pre-specified target negative predictive value (NPV) of ≥99.5%. The performance was then validated in a separate cohort of ED chest pain patients (n = 10 994). A historical hs-cTnT < 12 ng/L and a < 3 ng/L absolute change between the historical and the index visit hs-cTnT had the best performance and ruled out 24 862 (41%) patients in the derivation cohort. In the validation cohort, these criteria identified 4764 (43%) low-risk patients in whom 18 (0.4%) MIs within 30 days occurred, and had an NPV for MI of 99.6% (99.4-99.8), a sensitivity of 96.9% (95.2-.2), and an LR- of 0.11 (0.07-0.14).

Combining a historical hs-cTnT with a single new hs-cTnT may safely rule out MI and thereby reduce the need for serial hs-cTnT measurements in ED patients with chest pain.

The question addressed was 'Are NOACs as safe and efficient as vitamin K antagonist regarding thromboembolic prophylaxis and major bleeding in patients with surgical bioprosthesis and atrial fibrillation within 3 months of surgery?' Altogether more than 324 papers were found using the reported search, of which 6 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. The RIVER and ENAVLE trials showed non-inferiority of rivaroxaban (regarding mean time free from composite of death, major cardiovascular events or major bleeding at 12 months) and edoxaban (composite of death, clinical thromboembolic events or asymptomatic intracardiac thrombosis; and major bleeding) when compared with vitamin K antagonist. These studies include a low number of patients within 3 months of index surgery and overall low statistical power regarding this particular subgroup of patients.
