Purpose: Infective endocarditis (IE) is widely underdiagnosed or diagnosed after a major delay. The diagnosis is currently based on the modified DUKE criteria, where the only validated imaging technique is echocardiography, and remains challenging especially in patients with an implantable cardiac device. The aim of this study was to assess the incremental diagnostic role of (18)F-FDG PET/CT in patients with an implanted cardiac device and suspected IE.
Methods: We prospectively analysed 27 consecutive patients with an implantable device evaluated for suspected device-related IE between January 2011 and June 2013. The diagnostic probability of IE was defined at presentation according to the modified DUKE criteria. PET/CT was performed as soon as possible following the clinical suspicion of IE. Patients then underwent medical or surgical treatment based on the overall clinical evaluation. During follow-up, we considered: lead cultures in patients who underwent extraction, direct inspection and lead cultures in those who underwent surgery, and a clinical/instrumental reevaluation after at least 6 months in patients who received antimicrobial treatment or had an alternative diagnosis and were not treated for IE. After the follow-up period, the diagnosis was systematically reviewed by the multidisciplinary team using the modified DUKE criteria and considering the new findings.
Results: Among the ten patients with a positive PET/CT scan, seven received a final diagnosis of "definite IE", one of "possible IE" and two of "IE rejected". Among the 17 patients with a negative PET/CT scan, four were false-negative and received a final diagnosis of definite IE. These patients underwent PET/CT after having started antibiotic therapy (≥48 h) or had a technically suboptimal examination.
Conclusion: In patients with a cardiac device, PET/CT increases the diagnostic accuracy of the modified Duke criteria for IE, particularly in the subset of patients with possible IE in whom it may help the clinician manage a challenging situation.

Reading fluency is a vital building block for developing literacy, yet the best way to practice fluency-reading aloud-can cause anxiety severe enough to inhibit literacy development in ways that can have an adverse effect on students through adulthood. One promising intervention to mitigate oral reading anxiety is to have children read aloud to a robot. Although observations in prior work have suggested that people likely feel more comfortable in the presence of a robot instead of a human, few studies have empirically demonstrated that people feel less anxious performing in front of a robot compared with a human or used objective physiological indicators to identify decreased anxiety.

Continuous monitoring of cardiovascular vital signs can reduce the incidence and mortality of cardiovascular diseases, yet cannot be implemented by current technologies because of device bulkiness and rigidity. Here, we report self-adhesive and skin-conformal ultrasonic transducer arrays that enable wearable monitoring of multiple hemodynamic parameters without interfering with daily activities. A skin-adaptive focused ultrasound method with rational array design is proposed to implement measurement under wide ranges of skin curvatures and depths with improved sensing performances.

Endotracheal intubation is a critical medical procedure for protecting a patient's airway. Current intubation technology requires extensive anatomical knowledge, training, technical skill, and a clear view of the glottic opening. However, all of these may be limited during emergency care for trauma and cardiac arrest outside the hospital, where first-pass failure is nearly 35%.

Objectives: Failure of vascular closure device (VCD) is the most common cause of access-site vascular complications in transfemoral transcatheter aortic valve implantation (TAVI). The authors sought to determine if the systematic use of arteriotomy-site ballooning with concomitant manual compression following the delivery of a plug-based VCD (MANTA, Teleflex) can optimize toggle-plug assembly apposition to the common femoral artery (CFA) wall and improve the final hemostatic efficacy.
Methods: In this prospective, observational, single-center study, 323 consecutive patients undergoing transfemoral TAVI from October 2021 to December 2024 underwent access closure with the MANTA VCD.
