There is enough evidence that, nowadays, the sedentary lifestyle is one of the major health problems worldwide, linked to many chronic diseases, including mental comorbidities, systemic hypertension, metabolic dysregulation, and cancer. Although health societies recommend engagement to physical activities, there is an overwhelming number of people remaining sedentary, even knowing the health benefits of regular exercises. One of the main factors that justifies this scenario is the lack of motivation, which is a barrier to people intended to start new habits for health. Considering this previous information, new alternatives for exercises may help people engage in a healthier lifestyle. Technology has contributed to this with devices that allow movements based on virtual reality approaches, including the exergames. These are games available even in commercial devices, as video-games, that allow people to work with different physical components. Furthermore, exergames add cognitive gain through its dual-task characteristic. Moreover, due to the combination of these benefits, they are feasible to acquire, and easy to use. Exergames are not only a potential strategy to reduce sedentary lifestyle but also a good method to improve health gains and rehabilitation in different populations and pathological conditions: older adults, stroke survivors, and Parkinson’s disease. In this review, we aim to demonstrate some conditions that literature supports the intervention with exergames due to its physical and cognitive benefits. Furthermore, at the end of this review, we also explore the neurobiological mechanisms behind virtual-reality based exercises.

Abstract Scale has been a defining criterion of mapmaking for centuries. However, this criterion is fundamentally questioned by highly immersive virtual reality (VR) systems able to represent geographic environments at a high level of detail and, thus, providing the user with a feeling of being present in VR space. In this paper, we will use the concept of scale as a vehicle for discussing some of the main differences between immersive VR and non-immersive geovisualization products. Based on a short review of diverging meanings of scale we will propose possible approaches to the issue of both spatial and temporal scale in immersive VR. Our considerations shall encourage a more detailed treatment of the specific characteristics of immersive geovisualization to facilitate deeper conceptual integration of immersive and non-immersive visualization in the realm of cartography.

Audience Engagement

OVERVIEWThe last 20 years mark a period of transformation from a traditional model of displaying archaeology to a more immersive model supported by digital and virtual media. The traditional model has generally used glass cases accompanied by extensive texts to inform visitors, whereas the immersive model employs digital media, tablets, virtual reality, and augmented reality to attract and engage a wide audience. In light of the recent enthusiasm for the latter, however, one must ask whether such immersive exhibitions are merely superficial means to make public institutions more attractive without having a meaningful impact on audience engagement. Polish archaeological museums provide interesting sites through which to explore this predicament. Here, digital upgrades are generously financed by national funds, so the traditional model of the archaeological museum in Poland is currently almost absent. In this short review, I aim to discuss one of the most interesting examples of temporary digital archaeological exhibitions organized between 2014 and 2019 in the Polish capital of Warsaw. I investigate its potential to engage audiences, ultimately concluding that it managed to create an interesting counterweight to traditional displays and respond to the drawbacks of new digital exhibitions through novel aesthetics and alternative archaeological storytelling.

AbstractLiterature has proven that COVID-19 patients develop pneumonia. Prognosis of this is poor in case of COVID-19 patients developing the following: low lymphocyte count (< 16%) which gets lower with active COVID-19 infection, sedentary lifestyle, obesity, and uncontrolled diabetes mellitus with no exercise. A lot of dilemmas and myths in this nascent COVID-19 pandemic period exist regarding the use of ECMO. Perplexities such as do we treat the COVID-19 patients on ECMO, as a pulmonary ARDS pneumonia, and/or do we need high PEEP or moderate PEEP, during ECMO for this ARDS; are some common COVID-19 ECMO myths which this short review aims to cover in a question-answer format.

Individuals with mild cognitive impairment are at risk of cognitive and physical decline. Virtual reality (VR) exercise may provide beneficial physical and cognitive exercise. The objectives of this study were to assess the feasibility and safety of home-based VR exercise and to provide pilot data for physical and cognitive efficacy. Eleven individuals with mild cognitive impairment (seven males/four females, average 78 years old, and average 3 years since diagnosis) performed a 30-min home-based VR exercise program 5 days a week for 6 weeks. The VR platform was successfully installed in participants’ homes, and all participants were able to learn the VR program and progress. Participants completed 99% of the prescribed exercise. There were no major adverse events. Most participants enjoyed the VR program and reported physical benefits; fewer reported cognitive benefits. No physical or cognitive outcome measures showed change after 6 weeks. Home-based VR exercise is safe and feasible in individuals with mild cognitive impairment.

The objective is to short review the current state of the art of virtual reality medical application in term of minimal invasive dentistry. An outline of the most important aspects of virtual reality has been created, and a subsequent literature search for articles related was conducted. The current state of the art of virtual reality includes a variety of applications, among others premedication, analgesics, anaesthetics plays an important role in informatics medicine. There is a growing consensus regarding the need to develop knowledge and possible introduce virtual reality as a non-pharmacological support for dental treatment.

Major Cardiovascular Events

Systemic hypertension (HTN) is the most prevalent non-communicable disease and the leading cause for major cardiovascular events, renal failure and cognitive decline. The World Health Organization showed that HTN is a key area of concern for healthcare and identified this condition as one of the primary targets for intervention to reduce global morbidity and mortality. The hard-hitting AHA/ACC Guidelines on management of High blood pressure in adults published in 2017 shocked medical community and enforced reconsidering overall significance HTN once again due to the large pool of newly diagnosed individuals and higher healthcare costs. Ensuing debates around Task Force committee opinions were fomenting at every scientific session related to cardiac diseases throughout first half-year 2018 and beyond the lecture halls as well. Thus all attendees at the 28th European Congress on Hypertension and Cardiovascular Protection held in Barcelona, Spain in June were captivated with the European expert’s presented preview of the new 2018 ESH/ESC joint clinical Guidelines on diagnosis and management of HTN. This short review highlights the bullet points presented before fulltext publication. The chapters on diagnosis, risk stratification, blood pressure treatment target ranges had undergone minor but crucial corrections. Key changes include medical treatment of uncomplicated HTN and drug therapy in special groups with major comorbidities, management of resistant HTN, device-based HTN therapy and adherence interventions.

Potential Strategy

AbstractCatalyst-free thermal polyesterification has recently emerged as a potential strategy for designing biodegradable thermoset polymers, particularly polyol-based polyesters for biomedical applications. These thermoset polyesters are synthesized through polycondensation of polyol and polyacid without the presence of catalyst or solvents. The mechanical properties, degradation rates, crystallinity, hydrophilicity, and biocompatibility can be controlled by adjusting the monomer feed ratios and curing conditions. These polyesters often degrade via surface erosion that allows the polymers to maintain structural integrity throughout hydrolysis. Additionally, polyol-based polyesters demonstrated good biocompatibility as non-toxic catalysts and/or solvents involved in the reaction, and the monomers used are endogenous to human metabolism which can be resorbed and metabolized in various physiological pathways. This review summarizes the polyol-based biodegradable polyesters that were synthesized by catalyst-free polyesterification.
