Background Till date, there have been no studies that have analyzed a database to examine postmarket adverse events associated with PROPEL mometasone furoate bioabsorbable drug-eluting sinus stents. Objective To determine the postmarket complications associated with PROPEL mometasone furoate bioabsorbable drug-eluting sinus stents. Methods The US Food and Drug Administration’s Manufacturer and User Facility Device Experience database was searched for adverse events associated with PROPEL bioabsorbable drug-eluting sinus stents between January 1, 2012 and December 31, 2020. Data were extracted and analyzed from medical device reports (MDRs) that involved sinus stents. Results After 47 MDRs were identified, 25 reports involving PROPEL bioabsorbable drug-eluting sinus stents were reviewed, from which 40 adverse events were recorded. Of these, there were 32 adverse events to patients and 8 device malfunctions. The most common adverse events to patients included infection (21.8%), oropharyngeal obstruction (15.6%), and headache/pain (12.5%). The most common device malfunction reported was migration and expulsion of the stent (87.5%). Conclusions PROPEL sinus stents have been shown to be effective in preventing sinus outflow obstruction after functional endoscopic sinus surgery. Both adverse events to patients and device malfunctions are reported infrequently. A more comprehensive understanding of rare postmarket complications seen with PROPEL sinus stents may further aid informed decision-making regarding their usage.

Purpose: To evaluate the safety and efficacy of long vascular sheaths for transfemoral neuroendovascular procedures in children.Materials and Methods: A retrospective evaluation of transfemoral neuroendovascular procedures in children <18 years, using long sheaths was undertaken analyzing procedure type, fluoroscopic times, technical success, access site and systemic complications. Twenty-seven consecutive procedures were included over a two-year period. Mean age was 8.4 years (standard deviation [SD] 6.3) (range 17.0 months–16.3 years).Results: Patients were 44% female and mean weight was 35.0 kg (SD 22.8) (range 9.8–72.2 kg). A third of the procedures were performed in ≤15 kg children. The most common procedure was for embolization (n=13, 48.1%) and the most common indication was dual microcatheter technique (52%). The most common device used was the 5 Fr Cook Shuttle sheath. Mean fluoroscopy time was 61.9 minutes (SD 43.1). Of these procedures, 93% were technically successful. Femoral vasospasm, when present, was self-limiting. Complications (3/27, 11.1%) included groin hematoma (n=1), neck vessel spasm that resolved with verapamil (n=1), and intracranial thromboembolism (n=1), with no significant difference between the ≤15 kg and >15 kg subcohorts. There were no aorto-femoro-iliac or limb-ischemic complications.Conclusion: Long vascular sheaths without short femoral sheaths can be safely used for pediatric neuroendovascular procedures as they effectively increase inner diameter access without increasing the outer sheath diameter. This property increases the range of devices used and intracranial techniques that can be safely performed without arterial compromise, thus increasing the repertoire of the neurointerventionalist.

In late 2020, Venture Insights conducted a video consumer survey of 1,003 Australian households. This paper provides an overview of the results. A television set remains the most common device for watching video, but a substantial majority of households also watch video on PCs, tablets and smartphones. Internet-connected TVs are now common. Only 24% of households currently have a 4K or better TV, but 44% of households anticipate buying a 4K TV set over the next three years. More than half of households do not subscribe to a pay-TV service. Of those which do, two-thirds have Foxtel. Netflix remains dominant in the Australian subscription video market, while its main competitors are each subscribed to by about one-fifth of households. Most survey respondents expect their video consumption to remain stable across all formats over the next year.

The development of technology brings the computerization of everyday life. The most common device used to communicate with a computer is the keyboard. Many papers have been devoted to the study of computer keyboards and virtual keyboards. The authors of this study propose a new concept of a single line keyboard named One Row Keyboard (ORK) which can be applied for both computer and virtual keyboards. Applying the proposed concept enables the number of keys on the keyboards to be reduced significantly. This allows for the development of keyboards even on really small mobile devices. The article also presents a new method of assigning characters to keys for the ORK and shows the use of this method to create exemplary ORK layouts. One Row Keyboard is also the first concept that makes it possible to create a fully alternating keyboard. Noteworthy is that the criterion of maximizing typing alternation is the most popular criterion for keyboard optimization used in the studies devoted to computer keyboards as it leads to an increase in typing speed and decrease in the number of errors.

Shower head, also known as shower head, is a device that allows water to diverge and flow out in the form of droplets or sprays. It was originally a device for watering flowers, potted plants and other plants. Later, someone modified it to be used as a shower, making it a common device in the bathroom, called a shower head, mainly used for showering in households or public places. In terms of structure, the shower is generally composed of a body, a switching component, a water distribution component, a rotor, a water outlet, a face cover, a water outlet component, a water-saving device, a plug, a button, and so on. This article mainly analyzes the industrial distribution of shower heads, product quality spot checks and the causes of quality problems.

AbstractThe electrosurgical unit (ESU) is the most common device in modern surgery for cutting and coagulation of tissues. It produces high-frequency alternating current to prevent the stimulation of muscles and nerves. The commercial ESUs are generally expensive and their output power is uncontrolled. The main objective of the proposed study is to propose an economic ESU with an additional feature of output power regulation using a fuzzy logic controller (FLC) based proportional integral derivative (PID) tuned controller. Unlike the previous studies, the proposed controller is designed in a fully closed-loop control fashion to regulate the output power of the ESU to a fixed value under the consideration of highly dynamic tissue impedance. The performance of the proposed method is tested in the MATLAB/SIMULINK environment. In order to validate the superiority of the proposed method, a comparative analysis with a simple (PID) controller based ESU is presented.

With emphasis placed on the least restrictive learning environments under the Individuals with Disabilities Education Act (IDEA), students with disabilities are often placed in general education classrooms. As a result, the discussion of inclusion strategies has increased in special education. The rise in 1:1 device initiatives offers the inclusionary practice of giving all students within a school access to their own device, with Google’s Chromebook and Apple’s iPad being among the most common device choices. This article explains the potential uses of 1:1 devices for students in inclusion settings, including built-in accessibility features and implementation strategies for educators.

The article analyzes the theory of the origin of morality, presented by the Epicurean Hermarchus in his treatise “Against Empedocles” (Porph. De abstin. I, 7–12). The author expresses doubt on the established point of view that Hermarchus, in criticizing Empedocles, actually meant to criticize the philosophical schools of his day, and did not polemicize with the Pythagoreans and the followers of Empedocles, but with the Stoics, whom he did not name, but had in mind. Exploring the Peripatetic and Epicurean tradition of using terms close to the concept of oikeiōsis, which was introduced by Hermarchus to explain the prohibition of killing a person by another person, the author of the article expresses the opinion that Stoic Chrysippus, criticizing the teaching of the Epicureans about the aspiration for pleasure as a person’s primary impulse in his essay “On the ultimate goal”, used this Epicurean term in his theory of the origin of morality (Diog. Laert. VII, 85). Such an “interception” or reinterpretation of concepts was a fairly common device used by the Stoics in a polemic against Epicureanism. Hermarchus, unlike the Stoics, who understood oikeiōsis exclusively in the context of the emergence of individual self-awareness and feelings of self-preservation, spoke about the social meaning of oikeiōsis, which described people’s perception of each other within the human community and shows the impossibility of such an attitude towards living beings outside this community (to animals). Later, the term oikeiōsis was considered to be Stoic, and its creation was attributed to Zeno.
