The Transformation of Living Labor Under the Influence of Digitalization of the Economy

The purpose of the article is to identify and analyze the signs and features of the transformation of living labor under the influence of digitalization. The article examines the essence of the concept of «transformation of living labor» and the nature of the impact of digitalization of the economy thereupon; the directions of changes in living labor in the conditions of formation of the information and network economy were identified; changes in forms of employment in the context of the formation of the gig economy sector were substantiated; peculiarities of the functioning of digital platforms as a new type of basic economic institution and the scale of the influence of digital technologies on living labor through the prism of changes in the organic capital structure were revealed; the contours of the change in the formation of the cost of labor force as a result of a change in the owners of the means of production were indicated; the essence of digital capital was researched; the multidirectional nature of the processes that form the demand and supply of labor force in Ukraine was studied and substantiated. Based on the theories of transformation of systems and the labor economics, the concept of «transformation of living labor» is defined as changes in social and labor relations that arise in the processes of creating new value and reproduction of labor force. It is proposed to distinguish two levels of research on the transformation of living labor under the influence of digital technologies, namely: common to the economic environment and specific to the labor market, which made it possible to further determine the directions of its changes according to the characteristics of each of them, using the method of abstraction. The theoretical substantiation of changes according to the signs of two levels of transformation of living labor was further developed. For the first level, which defines the determinants of general shifts for the economic environment, it is proposed and substantiated to single out such features as: the transition from an industrial-market to an information-network economy; formation of the gig economy; formation of digital platforms; for the second level, which is specific to the labor market, the signs of transformation processes are as follows: creating conditions for the growth of the organic capital structure; changes in the formation of components of the cost of labor force as a result of a change in the owners of the means of production; formation of digital capital; multidirectional processes that form supply and demand in the labor market. The blocks by which it is advisable to examine the effectiveness of the use of digital platforms, according to the authors, can be: production costs; quality of products, works, services; use of working time; the level and quality of e-commerce; the level of economic relations; quality of access to information

POLLEN–FOOD ALLERGY SYNDROME AMONG CHILDREN WITH SENSITIZED TO SPRING TREES

It is known that among 40–70 % of patients pollinosis can run in conjunction with pollen-food allergy syndrome (PFS), while development of PFS is associated with the consumption of fresh fruits, vegetables, nuts and spices. Clinical course and severity of the disease depend on the sensitization profile, which can be represented by proteins-panallergens (PR-10, profilins, nsLTPs). However, there is little information about the sensitization profiles of patients with pollinosis caused by pollen of spring trees in Ukraine. Aim. To study the profiles of sensitization of children with spring pollinosis. Methods. We examined 61 children (aged 4-17 years) with spring seasonal allergic rhinitis/rhinoconjunctivitis (SAR). To establish the diagnosis, all children were given questionnaires, skin prick tests (SPTs) with commercial pollen extracts, and prick to prick tests with fresh fruits, vegetables and nuts. Component resolved diagnosis (CRD) were detected using an ImmunoCAP system. (Phadia, 100). Results. It has been found that in 43 children (70.5 %) had polinosis in combination with PFS, the main clinical manifestation of which was an oral allergic syndrome in 43 children (100 %). Among the causal food allergens that caused the manifestations of PFS were more apples, peaches, carrots and hazelnuts (consumption of which led to 11.6 % of children before the development of anaphylaxis). All of the examined children (100 %) had a positive IgE response to rBet v 1 at significant concentrations. In 9.3 % of children, panallergens were found at once from several botanical groups. Such panallergens: rBet v 2, rBet v 4, rPhl p 7, rPhl p 12, rArt v 3 are generally not defined in the control group children. Conclusions. Birch related PFS are common in Ukrainian pollen-allergic children with nuts and fruits predominantly implicated. Sensitization profile of children with Birch-pollen syndrome is complex and associated with sensitization to panalergens. Clinicians should be worried of PFS in patients with a high degree of sensitization to birch pollen and even young children if they have birch sensitization

Recommendations for asthma monitoring in children:A PeARL document endorsed by APAPARI, EAACI, INTERASMA, REG, and WAO

Monitoring is a major component of asthma management in children. Regular monitoring allows for diagnosis confirmation, treatment optimization, and natural history review. Numerous factors that may affect disease activity and patient well-being need to be monitored: response and adherence to treatment, disease control, disease progression, comorbidities, quality of life, medication side-effects, allergen and irritant exposures, diet and more. However, the prioritization of such factors and the selection of relevant assessment tools is an unmet need. Furthermore, rapidly developing technologies promise new opportunities for closer, or even “real-time,” monitoring between visits. Following an approach that included needs assessment, evidence appraisal, and Delphi consensus, the PeARL Think Tank, in collaboration with major international professional and patient organizations, has developed a set of 24 recommendations on pediatric asthma monitoring, to support healthcare professionals in decision-making and care pathway design. (Figure presented.).</p

Toward personalization of asthma treatment according to trigger factors

International audienceAsthma is a severe and chronic disabling disease affecting more than 300 million people worldwide. Although in the past few drugs for the treatment of asthma were available, new treatment options are currently emerging, which appear to be highly effective in certain subgroups of patients. Accordingly, there is a need for biomarkers that allow selection of patients for refined and personalized treatment strategies. Recently, serological chip tests based on microarrayed allergen molecules and peptides derived from the most common rhinovirus strains have been developed, which may discriminate 2 of the most common forms of asthma, that is, allergen- and virus-triggered asthma. In this perspective, we argue that classification of patients with asthma according to these common trigger factors may open new possibilities for personalized management of asthma
