Devices Used by 112 Personnel in the Covid-19 Pandemic Process, Validation and Problems Encountered

The emergency health service is for all interventions that are made up of people who have received special education in their field, who work together in order to provide the best emergency response to the sick and injured in the shortest time possible in line with the possibilities available. In this context, although the emergency health service provided during the pandemic process requires the implementation of special procedures for healthcare professionals, it is important in the validation of the biomedical devices used during the provision of this service. Especially the fact that this process was a disaster that took place in an unexpected time period caused everyone to be caught unprepared and this situation caused the current workload of healthcare workers to increase even more. In this study, we conducted a literature search to shed light on the problems experienced by 112 emergency healthcare professionals during the pandemic period and how the validation of the biomedical devices used by these personnel in the ambulance should be. The type of research is descriptive research. The Covid-19 pandemic was accepted as a case and the literature was reviewed, with this case being the focus. During the literature search, up-to-date keywords such as "emergency health service, Covid-19, disaster preparedness, emergency aid unit employees, biomedical device technologies", which are also mentioned in the keywords, were scanned. Care was taken to ensure that the studies included in the review section were up to date and in accordance with the academic guide. In addition, due to the limitation of resources in the validation section of the research, assistance was received from the relevant legislation and expert medical company engineers and from the active staff in the field of healthcare professionals' problems. As a result of this research, we have reached the conclusion that legal regulations should be made regarding the problems experienced by healthcare professionals due to the pandemic and that existing standards related to device validation should be updated after the pandemic.

E-Learning Based on Video Presentations to Enhances Attitudes, Skills, and Pedagogical Knowledge of Prospective Teacher Students During the Covid-19 Pandemic

This study aims to develop an e-learning tool based on video presentations to enhances attitudes, skills and pedagogical knowledges of prospective teacher students during the Covid-19 pandemic. This type of research is Research and Design (R & D) using the Plomp development model, which consists of 3 stages: a preliminary study, design, and assessment. Data collection was carried out through observation, device validation, distribution of response questionnaires, and assessment of student learning outcomes. The results of the data analysis show that at the preliminary study stage, it was found that there were still no devices that supported learning during the Covid-19 pandemic. At the stage of design was designed, including RPS, LMS Settings, and Video Presentations. At the assessment stage, it was found that all the tools developed had valid criteria, students gave a positive response to the small and broad trials respectively of 97.68%; 98.32% so that the tools developed were included in practical criteria. The assessment of learning outcomes in the aspects of attitudes, skills, and knowledge had average completeness on the small and broad trials respectively of 82.92%; 86.99% so that the equipment used was included in the effective criteria. Thus the device developed can be said to be feasible because it meets the criteria of validity, practicality, and effectiveness. The development of e-learning based on video presentations can be used to enhance attitudes, skills, and pedagogical knowledge of prospective mathematics teacher students.

Experimental Validation of a Microwave System for Brain Stroke 3-D Imaging

This paper experimentally validates the capability of a microwave prototype device to localize hemorrhages and ischemias within the brain as well as proposes an innovative calibration technique based on the measured data. In the reported experiments, a 3-D human-like head phantom is considered, where the brain is represented either with a homogeneous liquid mimicking brain dielectric properties or with ex vivo calf brains. The microwave imaging (MWI) system works at 1 GHz, and it is realized with a low-complexity architecture formed by an array of twenty-four printed monopole antennas. Each antenna is embedded into the “brick” of a semi-flexible dielectric matching medium, and it is positioned conformal to the head upper part. The imaging algorithm exploits a differential approach and provides 3-D images of the brain region. It employs the singular value decomposition of the discretized scattering operator obtained via accurate numerical models. The MWI system analysis shows promising reconstruction results and extends the device validation.

Implementation of Good Computer System Validation Practices In Pharmaceutical Industry- A Review

Computer Systems Validation is a method used to ensure information is generated by a computer-based system that satisfies a set of specified requirements. Compliance with computerized systems is becoming increasingly relevant in the pharmaceutical industry as computer system validations have many benefits, such as enhancing quality control, reducing other validation costs and time, improving compliance with GMP 21 CFR Part 11 Regulation which affects the quality, health, identification or effectiveness of products subject to the GMP Regulations. Both the European Medicines Agency of Europe along with the Food & Drug Administration of the USA has developed CSV practice guidelines. An overview of relevant documents which fulfil the computer system validation along with its best practices implemented is presented below. Official requirements and standards of the USA, Europe, and Switzerland are taken as the main focus. The taken basic GMP guidelines' like Gamp, AVP and PDA implies the same principles and theories. They explain majorly about what to do view point of validation, whereas GAMP describes how to do validation. We strive to define the computer device validation needs of equipment conducted from a pharmaceutical industry perspective. The categorization of a computer system into various frameworks or categories gives the flexible approach for the validation of complex as well as simple computerized systems. The present review article discusses the implementation and various good practices of the pharmaceutical industry to maintain computer system validation. Implementing various good computer system validation activities reduces the re-work and always maintains the quality standards as per the user requirements; as a result of which the future trends will notice merging of various new implemented terminology and techniques as a common practice in mixed sectors.

A Handheld Metabolic Device (Lumen) to Measure Fuel Utilization in Healthy Young Adults: Device Validation Study

Background Metabolic carts measure the carbon dioxide (CO2) produced and oxygen consumed by an individual when breathing to assess metabolic fuel usage (carbohydrates versus fats). However, these systems are expensive, time-consuming, and only available in health care laboratory settings. A small handheld device capable of determining metabolic fuel usage via CO2 from exhaled air has been developed. Objective The aim of this study is to evaluate the validity of a novel handheld device (Lumen) for measuring metabolic fuel utilization in healthy young adults. Methods Metabolic fuel usage was assessed in healthy participants (n=33; mean age 23.1 years, SD 3.9 years) via respiratory exchange ratio (RER) values obtained from a metabolic cart as well as % CO2 from the Lumen device. Measurements were performed at rest in two conditions: fasting, and after consuming 150 grams of glucose, in order to determine changes in metabolic fuel usage. Reduced major axis regression and simple linear regression were performed to test for agreement between RER and Lumen % CO2. Results Both RER and Lumen % CO2 significantly increased after glucose intake (P<.001 for both) compared with fasting conditions, by 0.089 and 0.28, respectively. Regression analyses revealed an agreement between the two measurements (F1,63=18.54; P<.001). Conclusions This study shows the validity of Lumen for detecting changes in metabolic fuel utilization in a comparable manner with a laboratory standard metabolic cart, providing the ability for real-time metabolic information for users under any circumstances.
