Exploring The Self-Regulatory Behaviors of Elementary Students with Hearing Loss in Inclusive Classrooms

An exploratory, mixed-method and multi-level research design was employed to examine relationships among students’ hearing loss, academic achievement and self-regulation (SR), classroom background noise levels, teachers’ perceptions of inclusion of students who are hard of hearing (HH) and features of classroom instruction that support SR. Data consisted of 10 elementary teachers’ perceptions of the inclusion, and ratings of 131 students’, of whom 8 were hard of hearing, SR and academic achievement scores. Classroom observations were conducted to obtain background noise levels and to examine whether and how teachers implement the features of classroom contexts to support SR within their classroom. Results indicated that a) hearing status predicted SR, b) SR predicted academic achievement for normal hearing (NH) and hard of hearing (HH) students, c) HH students’ received lower SR ratings than NH peers, and d) classroom background noise levels were negatively related to the use of features of instruction to support SR and to teachers’ knowledge and understanding of hearing loss. These results highlight the importance for further teacher education to emphasize a) the effects of hearing loss on learning and SR, b) the influence of classroom background noise levels on HH and NH students’ success, and c) effective strategies for creating an inclusive classroom

The Effects of Single Versus Multiple Training Sessions on the Motor Skill Retention of Two Krav Maga Strike Techniques: in Women

Krav Maga (KM) self-defense system experts claim that KM techniques are based on natural body movements, learned rapidly, and improved with additional training. This study investigated the retention and further improvement with additional training of two KM strike techniques: straight punch and defensive kick, in untrained females. All participants received an initial 30-minute instruction session (AQ) taught by a certified KM instructor. Participants were divided into an intervention group (n=8), which received four additional training sessions; and a control group (n=8), which received no additional training. Kinematics and kinetics of punch and kick strikes were recorded at three timepoints: immediately after AQ, five days after AQ, and twelve days after AQ. Skill level obtained during AQ did not degrade in either group. Additional training did not improve skill level beyond that learned during AQ, suggesting increased practice time, or restructuring of training protocol may be required for further skill improvement

Sutureless and rapid deployment valves: implantation technique from A to Z-the INTUITY Elite valve

In the last two decades, sutureless (Perceval, Livanova PLC, London, UK) and rapid deployment (INTUITY Elite, Edwards Lifesciences, Irvine, CA, USA) valves were introduced to the market as an innovative alternative to traditional valves for patients needing aortic valve replacement (AVR). These devices have been used and studied extensively across these fifteen years, and have proven to be a valid alternative treatment option compared to sutured biological valves, particularly helpful in minimally invasive cardiac surgery, and an almost curative treatment to patients with intermediate to high surgical risk, filling the gap between transcatheter and traditional AVR. However, both sutureless and rapid deployment valves require special steps for implantation, and also a learning curve. Proper specific training to all surgical team members is required as mandatory by the manufacturers. The aim of this review article is to provide cardiac surgeons with a thorough guide on the implantation technique from A to Z, for each of these two prosthetic devices. In this second part of our review article, we will focus on the INTUITY Elite valve

Sutureless and rapid deployment valves: Implantation technique from A to Z-the perceval valve

In the last two decades, sutureless (Perceval, Livallova PLC, London, UK) and rapid deployment valves (RD) (Intuity, Edwards Lifesciences, Irvine, CA, USA) were introduced to the market as an innovative alternative to traditional valves for patients requiring an aortic valve replacement (AVR). These devices have been studied extensively and in use across the last fifteen years. They have proven to not only demonstrate comparable results with conventional sutured biological valves-particularly helpful in minimally invasive cardiac surgery-but also provide an almost curative treatment to patients with intermediate-to-high surgical risk, filling the gap between transcatheter aortic valve implantation (TAVI) and traditional AVR. However, both sutureless and RD valves require special steps for implantation, resulting in a learning curve. Specific training for all surgical team members is mandatory, as recommended by the manufacturers. The aim of this review article is therefore to provide cardiac surgeons with a thorough guide on the implantation technique for each of these two prosthetic devices, from A to Z. In this first article, we will start by focusing on Perceval

Minimally invasive aortic valve surgery

Since their introduction, it has been demonstrated that minimally invasive aortic valve replacement (MIAVR) approaches are safe and effective for the treatment of aortic valve diseases. To date, the main advantage of these approaches is represented by the reduced surgical trauma, with a subsequent reduced complication rate and faster recovery. This makes such approaches an appealing choice also for frail patients [obese, aged, chronic obstructive pulmonary disease (COPD)]. The standardization of the minimally invasive techniques, together with the implementation of preoperative workup and anesthesiological intraand post-operative care, led to an amelioration of surgical results and reduction of surgical times. Moreover, the improvement of surgical technology and the introduction of new devices such as sutureless and rapid deployment (SURD) valves, has helped the achievement of comparable results to traditional surgery. However, transcatheter technologies are nowadays more and more important in the treatment of aortic valve disease, also in low risk patients. For this reason surgeons should put new efforts for further reducing the surgical trauma in the future, even taking inspiration from other disciplines. In this review, we aim to present a review of literature evidences regarding minimally invasive treatment of aortic diseases, also reflecting our personal experience with MIAVR techniques. This review could represent a tool for a well-structured patient assessment and preoperative planning, in order to safely carrying out an MIAVR procedure with satisfactory outcomes

Mitral Valve Repair Techniques With Neochords: When Sizing Matters

Mitral valve (MV) repair procedures have evolved over time and multiple approaches have been proposed also for the repair with neochords implantation. This article compiles the currently available approaches for implanting and sizing neochords, to restore a proper coaptation of the MV leaflets and a good systo-dyastolic movement. The described techniques are aimed at standardizing chordal measurement, in order to reduce variability in chordal length. The placement of annuloplasty ring before chordae implantation should be avoided. Regardless of the technique chosen, it is important that the implanted chordae do not interfere with normal native chordae, to avoid the risk that neochordae may heal together or get damaged. This article aims to give an overview of the most common sizing techniques available
