In countries where headache services exist at all, their focus is usually on specialist (tertiary) care. This is clinically and economically inappropriate: most headache disorders can effectively and more efficiently (and at lower cost) be treated in educationally supported primary care. At the same time, compartmentalizing divisions between primary, secondary and tertiary care in many health-care systems create multiple inefficiencies, confronting patients attempting to navigate these levels (the “patient journey”) with perplexing obstacles. High demand for headache care, estimated here in a needs-assessment exercise, is the biggest of the challenges to reform. It is also the principal reason why reform is necessary. The structured headache services model presented here by experts from all world regions on behalf of the Global Campaign against Headache is the suggested health-care solution to headache. It develops and refines previous proposals, responding to the challenge of high demand by basing headache services in primary care, with two supporting arguments. First, only primary care can deliver headache services equitably to the large numbers of people needing it. Second, with educational supports, they can do so effectively to most of these people. The model calls for vertical integration between care levels (primary, secondary and tertiary), and protection of the more advanced levels for the minority of patients who need them. At the same time, it is amenable to horizontal integration with other care services. It is adaptable according to the broader national or regional health services in which headache services should be embedded. It is, according to evidence and argument presented, an efficient and cost-effective model, but these are claims to be tested in formal economic analyses.

At the time of writing this (October 14, 2020), more than 38.4 million people have become affected, and 1.0 million people have died across the world. The death rate is undoubtedly correlated with the cytokine storm and other pathological pulmonary characteristics, as a result of which the lungs cannot provide sufficient oxygen to the body's vital organs. While diversified drugs have been tested as a first line therapy, the complexity of fatal cases has not been reduced so far, and the world is looking for a treatment to combat the virus. However, to date, and despite such promise, we have received very limited information about the potential of nanomedicine to fight against COVID-19 or as an adjunct therapy in the treatment regimen. Over the past two decades, various therapeutic strategies, including direct-acting antiviral drugs, immunomodulators, a few non-specific drugs (simple to complex), have been explored to treat Acute Respiratory Distress Syndrome (ARDS), Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS), influenza, and sometimes the common flu, thus, correlating and developing specific drugs centric to COVID-19 is possible. This review article focuses on the pulmonary pathology caused by SARS-CoV-2 and other viral pathogens, highlighting possible nanomedicine therapeutic strategies that should be further tested immediately.

© 2020 The Authors Regulated cell death (RCD) has a fundamental role in development, pathology, and tissue homeostasis. In order to understand the RCD mechanisms, it is essential to follow these processes in real time. Here, atomic force microscopy (AFM) is applied to morphologically and mechanically characterize four RCD modalities (intrinsic and extrinsic apoptosis, necroptosis, and ferroptosis) in murine tumor cell lines. The nano-topographical analysis revealed a distinct surface morphology in case of necroptosis, ∼ 200 nm membrane disruptions are observed. Using mechanical measurements, it is possible to detect the early onset of RCD. Combined elasticity and microrheology analysis allowed for a clear distinction between apoptotic and regulated necrotic cell death. Finally, immunofluorescence analysis of the cytoskeleton structure during the RCD processes confirm the measured mechanical changes. The results of this study not only demonstrate the possibility of early real-time cell death detection but also reveal important differences in the cytoskeletal dynamics between multiple RCD modalities.

Multifactorial nature of human health and need in personifying the approach to each person in the health saving programs should use modern information and cognitive technologies for the tasks of health assessment and control. The article presents a concept, basic methods, and a structure of intelligent system of health saving (InSyHS), created by the authors to solve these tasks. This system implements the intelligent Internet technology based on modern cognitive methods and information about health, considering all possible health-determining essential factors (nutrition, physical activity, lifestyle, social and nature environment), and doing people to form an active relation to health with the possibility of self-diagnostics (physical and mental reserves, stress, psycho-emotional characteristics), optimization and personalization of personal health saving programs.

© 2018 Elsevier Ltd In this review, we describe dielectric properties of biological tissues and liquids in the context of terahertz (THz) biophotonics. We discuss a model of the THz dielectric permittivity of water and water-containing media, which yields analysis of the relaxation and damped resonant molecules modes. We briefly describe modern techniques of THz spectroscopy and imaging employed in biophotonics with a strong emphasize on a THz time-domain spectroscopy. Furthermore, we consider the methods of sub-wavelength resolution THz imaging and the problem of THz wave delivery to hard to access tissues and internal organs. We consider the THz dielectric properties of biological solutions and liquids. Although strong absorption by water molecules prevents THz-waves from penetration of hydrated tissues and probing biological molecules in aqueous solutions, we discuss approaches for overcoming these drawbacks – novel techniques of freezing and temporal dehydration by application of hyperosmotic agents which have a potential for cancer detection. We review recent applications of THz technology in diagnosis of malignancies and aiding histology paying particular attention to the origin of contrast observed between healthy and pathological tissues. We consider recent applications of THz reflectometry in sensing the thinning dynamics of human pre-corneal tear film. Modern modalities of THz imaging, which relies on the concepts of multi-spectral and multi-temporal domains and employing the principles of color vision, phase analysis and tomography are discussed. Novel methods of THz spectra analysis based on machine learning, pattern recognition, chemical imaging and the revealing of the spatial distribution of various substances in a tissue, are analyzed. Advanced thermal model describing biological object irradiated by THz waves and phantoms mimicking the optical properties of tissues at THz frequencies are presented. Finally, application of the high-resolution THz spectroscopy in analytic chemistry, biology and medicine are described.

© 2018 Elsevier Ltd Human stem cells, including pluripotent, embryonic and mesenchymal, stem cells play pivotal roles in cell-based therapies. Over the past decades, various methods for expansion and differentiation of stem cells have been developed to satisfy the burgeoning clinical demands. One of the most widely endorsed technologies for producing large cell quantities is using microcarriers (MCs) in bioreactor culture systems. In this review, we focus on microcarriers properties that can manipulate the expansion and fate of stem cells. Here, we provide an overview of commercially available MCs and focus on novel stimulus responsive MCs controlled by temperature, pH and field changes. Different features of MCs including composition, surface coating, morphology, geometry/size, surface functionalization, charge and mechanical properties, and their cellular effects are also highlighted. We then conclude with current challenges and outlook on this promising technology.

© 2018 IEEE. We have proposed an approach to improve the resolution of terahertz (THz) imaging using the effect of solid immersion - i.e. a reduction in the dimensions of the electromagnetic beam caustic by its formation in a free space, behind the medium possessing high refractive index. We have designed a THz solid immersion lens (SIL) comprised of a polymer wide-aperture aspherical singlet and a crystalline truncated sphere mounted in front of the image plane. We have proposed an approach for the object handling at the focal plane of the THz SIL. We have combined numerical simulations and experimental studies to demonstrate the advanced 0.2λ spatial resolution of the proposed THz SIL - it is beyond the 0.5λ Abbe limit. Finally, we have assembled the continuous-wave THz SIL imaging system and applied it for studying various objects with sub-wavelength variations of structure and dielectric properties.

The gelatin embedding yields sustain the THz response of tissues close to that of the freshly-excised ones for a long time after the resection. We have observed significant differences between the THz responses of normal and pathological tissues of the brain, which highlights a potential of the THz technology in label-free intraoperative neurodiagnosis of tumors.

© 2018 IEEE. We have proposed a method of THz solid immersion microscopy, which yields imaging soft biological tissues with the sub-wavelength resolution up to 0.2-wavelengths. To achieve this advanced resolution, it employs a solid immersion phenomenon - i.e. a reduction in the dimensions of the THz beam caustic by its formation on a small distance behind the medium featuring high refractive index. We have assembled an experimental setup, which realizes the principles of the THz solid immersion microscopy, and proposed an approach for handling the soft tissue at the object plane. This setup uses a backward-wave oscillator, as a source of continuous-wave THz radiation, and a Golay cell, as a detector of the THz field intensity. We have examined the resolution of the THz solid immersion microscopy using both numerical simulations and experimental studies. Finally, in order to highlight the prospective of the proposed THz imaging modality, we have applied the experimental setup for imaging of representative examples of biological tissues.

Anthropogenic physical, chemical, and biological impacts of objects on living organisms in the environment lead to profound structural and functional disorders primarily in the evolutionary current microbiocenosеs of a human. This is often accompanied by a deterioration in his health, an increase in the risk of infectious, chronic metabolic and mental diseases, which eventually can put a question for not only the preservation on our planet but also the entire existing diversity of living organisms. The development of cryobiotechnology and the creation of cryobanks of different directions is a common global trend in the development of Biological, Medical, Agricultural and Environmental Sciences. The advantage of the proposed technique of cryopreservation of symbiotic microbial associations is the storage of the biomaterials taken from the people will be carried out in an atmosphere of liquid nitrogen (-196°C) for the long-term storage. Fundamental and applied research on cryopreservation of microbiota of different human biotopes has a social orientation because they are directly related to human ecology and health of the nation.

In the article, an overview of the information on the method and application technology of SWOT (Strengths, Weaknesses Opportunities, Threats) analysis is presented. The specific characters of the method, the object domain of its application, the task, the methodology are disclosed. An interesting idea is the scheme of the options used to achieve more complete benefit from the method. The strengths and the shortcomings of the SWOT analysis noted by experts in the field of its application are given. Further on, the authors propose an innovative technology for using the SWOT model to develop personalized forecasting, preservation, development, and management of health, based on the provisions of the functional direction of genetics - phenomics. The advantages of technology, the urgency of its application are revealed. The new technology is based on provisions of the development of the theory of the essential adaptation. To ensure the state of health the functioning level of the body's systems must be consistent with the optimality, namely with their response norms, which determine the individual phenotype. In the process of the organism adaptation to the conditions of the external environment, the central nervous system (it's a known fact) and the significant body system (the system with the maximum response norm), determining, respectively, the specific and nonspecific responses of the organism will be released by their activity. In the interaction of body systems, it is important to take the ordering into consideration. Dominant systems can actively involve other systems of the body to the process of adaptation according to the principle of the interaction with them, by strengthening or decreasing their activity. Taking into account the direction of interaction (inhibition, toning), this fact becomes important for understanding the pathogenesis of diseases, their targeted prevention, and treatment. A comprehensive record of the mechanisms of the formation of a specific and nonspecific reaction is used in the interest of identifying and effectively preventing functional disorders in the body. The SWOT analysis technology of personalized forecasting, preservation, development and health management eliminates the main drawbacks of SWOT analysis. On the other hand, the SWOT analysis technology helps to expand the range of application of phenomics, depending on the opportunities and threats of the environment.

© Authors. The information society reveals the social impact of the dissemination of information technologies. The purpose of this article is to study the negative social, psychological, and pedagogical implications of the Internet on young people. The authors analyzed the internet addiction problem among students (14-19 years) from the standpoint of the social health of the individuals and society as a whole. In a pilot study, which involved more than 600 adolescent participants aged 14-19 years (secondary school, college and university students), the authors have defined internet addiction as a complex phenomenon. The prerequisites of its development identify and highlights its formation in stages among students (mild fascination, passion, addiction, attachment). At the ascertaining stage of the experiment, a screening study was carried out to examine the state of internet addiction in young students in social networks. The results showed the necessity to design and implement internet addiction prevention programs for young students, which include three main blocks (motivational and cognitive, practice-oriented, reflexive), and a systematic plan for its implementation in the educational space framework. The stages of the experiment provided evidence of the authors' proposed effectiveness of methodologies for young people aged 14-19 years. This article may be useful to pedagogues, psychologists, and parents of students, social workers, and researchers working in the field of addiction prevention among young people.

To avoid the mismatch between crystalline parameters of In x Ga 1-x As and GaAs wafer we proposed to incorporate a step-graded metamorphic buffer layer. We showed that x increase strongly enhances THz emission and broadens THz spectrum of In x Ga 1-x As. Since no polarity rehearsal of the THz waveform occurs and electron diffusion mobility increases up to 90% with x increase we attribute the increase of THz intensity to photo-Dember effect contribution. The maximum efficiency of optical-to-THz conversion was obtained for In 0.72 Ga 0.28 As at optical fluence ∼0.01 μJ=cm 2 . The fabricated photoconductors can be used as promising photo-Dember or lateral photo-Dember THz emitters in pulsed THz spectroscopy and imaging, in particular, operating with long wave optical pump.
