Shockwave intravascular lithoplasty for the treatment of calcified carotid artery stenosis: A very early single-center experience
2020
Endovascular treatment of calcified carotid disease represents one of the main challenges for the interventionalists. Plaque calcium load is one of the most important factors affecting the risk of procedural complications. A new tool called Shockwave intravascular lithotripsy (S-IVL; Shockwave Medical, Inc.) has been recently approved for the treatment of heavily calcified coronary and lower limb arteries but minimal data exist about the treatment of carotid arteries. We report our early experience of carotid stenting using S-IVL. We report two cases of symptomatic patients with severely calcified carotid artery diseases who were turned down for vascular surgeries. The first case was succes…
Official Statement of the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) on Electronic Cigarettes and IQOS®.
2019
The use of novel tobacco products, particularly the electronic cigarette (EC) and partial tobacco combustion devices (HnB systems: Heat not Burn), has increased exponentially, particularly among adolescents and young people. The health authorities and scientific societies have shown concern about issues surrounding safety and effectiveness (as a method of smoking cessation). A study of the available scientific evidence has concluded that the safety of the vapor or fumes inhaled by the users of these devices cannot be guaranteed. Contradictory results from various clinical trials and meta-analyses also mean that these devices cannot be recommended for their effectiveness in cessation, especi…
Repetition without Repetition or Differential Learning of Multiple Techniques in Volleyball?
2021
A variety of approaches have been proposed for teaching several volleyball techniques to beginners, ranging from general ball familiarization to model-oriented repetition to highly variable learning. This study compared the effects of acquiring three volleyball techniques in parallel with three approaches. Female secondary school students (N = 42
Acute Effect of Alcohol Intake on Cardiovascular Autonomic Regulation During the First Hours of Sleep in a Large Real-World Sample of Finnish Employe…
2018
Background Sleep is fundamental for good health, and poor sleep has been associated with negative health outcomes. Alcohol consumption is a universal health behavior associated with poor sleep. In controlled laboratory studies, alcohol intake has been shown to alter physiology and disturb sleep homeostasis and architecture. The association between acute alcohol intake and physiological changes has not yet been studied in noncontrolled real-world settings. Objective The aim of this study was to assess the effects of alcohol intake on the autonomic nervous system (ANS) during sleep in a large noncontrolled sample of Finnish employees. Methods From a larger cohort, this study included 4098 su…
Mobile Technology Adoption and the Effects of Cultural Factors
2019
Mobile technologies are an important part of human life in both the personal and professional realms. Many services (banking, news, health, education, etc.) that traditionally offered either face-to-face, telephone, or other conventional platforms and technologies are now establishing services on mobile platforms as well. Mobile gadgets are now also being used by company employees as sales automation tools. The importance of culture in technology adoption and usage has been well-established. The adoption of any technology includes a set of factors that determine if the technology is either accepted or rejected, and the individual strengths of these determining factors may vary greatly, depe…
Zināšanu pārbaudes testi izmantošanai viedierīcēs
2018
Diplomdarbā aprakstītā pētījuma mērķis izpētīt mobilo testu izmantošanas aktualitāti un pielietošanas iespējas, lai veicinātu to izmantošanu pedagoģiskajā procesā. Pētījumam izmantoto datu ieguves kvalitatīvās metodes ir intervijas un platformu analīze, kvantitatīvā - pedagogu aptauja. Interviju respondenti ir sākumskolas, vidusskolas un augstskolas pedagogi, kā arī Uzdevumi.lv direktors Edgars Škutāns. Tika vadīts seminārs, iepazīstinot profesionālās vidusskolas Mediju mākslas nodaļas pedagogus ar zināšanu pārbaudes testu platformu QUIZIZZ, pēc kura tika veikta pedagogu aptauja. Pētījumā noskaidrots, ka viedierīcērs izmantojamo zināšanu pārbaudes testu galvenās priekšrocības ir automātiska…
Terminoloģijas lietojums mobilo iekārtu lietošanas instrukcijās
2018
Maģistra darbā pētīts terminoloģijas lietojums mobilo iekārtu lietošanas instrukcijās. Darba mērķis ir izpētīt vienotas terminoloģijas pieejamību tehniskās nozares terminoloģijai, kura izmantota mobilo iekārtu lietošanas pamācībās. Pētījumā izmantotās metodes ir teorētisko materiālu (grāmatu un publikāciju) apskats un izmantotās terminoloģijas un tās tulkojumu analīze. Pētījuma rezultāti liecina, ka lielākajai daļai no atlasītajiem terminiem nav pieejams vienots tulkojums, vai termins darināts latviešu valodā, kas secīgi noved pie situācijas, kurā tulkotājs kļūst par valodnieku, kuram jādarina terminoloģiskās frāzes.
Enhancing Light Emission in Interface Engineered Spin-OLEDs through Spin-Polarized Injection at High Voltages
2019
The quest for a spin-polarized organic light-emitting diode (spin-OLED) is a common goal in the emerging fields of molecular electronics and spintronics. In this device, two ferromagnetic (FM) electrodes are used to enhance the electroluminescence intensity of the OLED through a magnetic control of the spin polarization of the injected carriers. The major difficulty is that the driving voltage of an OLED device exceeds a few volts, while spin injection in organic materials is only efficient at low voltages. The fabrication of a spin-OLED that uses a conjugated polymer as bipolar spin collector layer and ferromagnetic electrodes is reported here. Through a careful engineering of the organic/…
Hands-feet wireless devices: Test-retest reliability and discriminant validity of motor measures in Parkinson's disease telemonitoring
2022
Background Telemonitoring, a branch of telemedicine, involves the use of technological tools to remotely detect clinical data and evaluate patients. Telemonitoring of patients with Parkinson's disease (PD) should be performed using reliable and discriminant motor measures. Furthermore, the method of data collection and transmission, and the type of subjects suitable for telemonitoring must be well defined. Objective To analyze differences in patients with PD and healthy controls (HC) with the wearable inertial device SensHands-SensFeet (SH-SF), adopting a standardized acquisition mode, to verify if motor measures provided by SH-SF have a high discriminating capacity and high intraclass corr…
In vitro comparison of the efficacy of two fractured implant-prosthesis screw extraction methods: Conventional versus mechanical.
2019
Abstract Statement of problem Implant-supported prostheses may be subject to esthetic, biological, or mechanical complications. Protocols for dealing with these mechanical problems are sparse. Purpose The purpose of this in vitro study was to compare the efficacy of a mechanical system for extracting fractured implant-prosthesis screws with the conventional method. Material and methods A total of 60 screws were divided into 2 groups according to their morphology (flat screws with a smooth shaft and threaded apical area and screws with a completely threaded body) and subjected to fatiguing and static load testing until fracture. The specimens were assigned to 3 operators with varying levels …
