Graphene for Antimicrobial and Coating Application

Graphene is a versatile compound with several outstanding properties, providing a combination of impressive surface area, high strength, thermal and electrical properties, with a wide array of functionalization possibilities. This review aims to present an introduction of graphene and presents a comprehensive up-to-date review of graphene as an antimicrobial and coating application in medicine and dentistry. Available articles on graphene for biomedical applications were reviewed from January 1957 to August 2020) using MEDLINE/PubMed, Web of Science, and ScienceDirect. The selected articles were included in this study. Extensive research on graphene in several fields exists. However, the available literature on graphene-based coatings in dentistry and medical implant technology is limited. Graphene exhibits high biocompatibility, corrosion prevention, antimicrobial properties to prevent the colonization of bacteria. Graphene coatings enhance adhesion of cells, osteogenic differentiation, and promote antibacterial activity to parts of titanium unaffected by the thermal treatment. Furthermore, the graphene layer can improve the surface properties of implants which can be used for biomedical applications. Hence, graphene and its derivatives may hold the key for the next revolution in dental and medical technology.

Smartwatch helps detects lung cancer: Using personal technology to advance healthcare

Summary The prevalence of smartwatches and other wearable medical technology has been increasing yearly. These watches offer a sensitive tool for capturing cardiac dysrhythmias and can lead to patients seeking earlier medical advice. This case report highlights the importance of clinicians seeking and using the information provided by wearable medical technology which in this case resulted in both the timely treatment of non-sustained ventricular tachycardia and lung adenocarcinoma.

Corona hotels in Israel: Care and abandonment under the auspices of digital medicine

Following the onset of the COVID-19 pandemic, Israel established a number of ‘corona hotels’ – hybrid spaces that were neither fully treatment-oriented nor fully incarcerational, in which people known or suspected to be infected with the coronavirus were confined, sometimes for prolonged and indefinite periods. This paper describes the experience of 25 people who were confined in corona recovery and isolation hotels between March and July 2020. The corona hotels exemplify how remote medical technology and digital medicine together enable a new ‘technogeography of care’, where care and abandonment are inextricably linked. The paper adds to the growing number of critical studies on digital health by showing how the employed technologies impact the concepts of human embodiment, subjectivity and social relations, as well as how the occupants negotiated the meaning of these technologies and resisted their effects.

Gambaran Radiologis pada Bidang Neurologis Tumor Otak

Along with increasing life expectancy and advances in medical technology, the incidence of brain tumors continues to increase. Brain tumors can cause changes in mental status, neurological deficits, and create a large social burden. The incidence of benign brain tumors is 71% and these benign brain tumors develop twice as often in women as in men. Diagnosis brain tumors requires radiological examinations that can quickly diagnose brain tumors and must be done immediately. Source searches were carried out on the online portal of journal publications as many as 20 sources from MedScape, Google Scholar and the Nation Center for Biotechnology Information / NCBI with the keywords "brain tumor" and "radiology of brain tumor". Brain tumors cause progressive neurological disorders. Neurologic disorders in brain tumors are usually caused by two factors, namely focal disturbances due to tumors and increased intracranial pressure. The most commonly used radiological techniques are T1/T2-Weighted MRI, MR Spectroscopy, Diffusion MRI, Perfusion MRI, and Brain Tumor CT Scan. MRI is a powerful and flexible instrument for evaluating patients with primary brain tumors. Integration of the RANO criteria into treatment evaluation helps reduce premature discontinuation of effective therapy due to treatment-related imaging changes.

IMPLEMENTATION OF THE LHP TECHNIQUE - LASER REMOVAL OF HEMORRHOIDS

Геморроидальная болезнь преследует человечество много тысячелетий. Основным проявлением болезни является выпадение узлов и геморроидальное кровотечение. Развитие медицинской технологии и внедрение современных методик, таких как LHP, позволяет получить хорошие результаты. При этом значительно уменьшаются страдания пациентов в послеоперационном периоде и наступает быстрая реабилитация. Hemorrhoidal disease has been haunting humanity for many millennia. The main manifestation of the disease is the loss of nodes and hemorrhoidal bleeding. The development of medical technology and the introduction of modern techniques, such as LHP, allows you to get good results. At the same time, the suffering of patients in the postoperative period is significantly reduced and rapid rehabilitation occurs.

Effects of Family Conflict and Social Support on Intention to Stay of Expatriates in Medical Technology Industry

Expatriates, during expatriation, would appear inadaptable feelings on work, life, and diet in different environment. Besides, expatriates, in medical technology industry, leaving home might neglect the family to result in imbalance between work and family. In this case, work-family conflict reveals the importance on expatriates. Expatriates in medical technology industry would appear psychosocial stress and conflict between work and life due to expatriation. Taking expatriates’ supervisors and expatriates in medical technology industry in southern Taiwan as the research object, total 360 copies of questionnaire are distributed, and the 278 valid copies are retrieved, with the retrieval rate 77%. The research results show that social support presents negative and significant effects on work-family conflict, work-family conflict reveals negative and remarkable effects on intention to stay, and social support appears positive effects on intention to stay. According to the results to propose suggestions, it is expected to provide healthy workplace in medical technology industry to improve expatriates’ work-family conflict and turnover.
