The aim of the work is to conduct a systematic analysis of the available research results on the possibility of using menopausal hormone therapy (MHT) in patients who successfully completed the treatment of endometrial cancer (EC). Materials and methods. The review includes data from foreign articles published in PubMed and Medline, and domestic works published on elibrary.ru over the past 40 years. Results. The results obtained allow us to consider MHT as an independent method of medical rehabilitation for women who have undergone EC. A clear patient profile should be established, allowing the use of this method, with strict adherence to health monitoring. Conclusion Patients who have successfully completed the treatment of EC require the creation of special rehabilitation conditions in the interests of maintaining health and quality of life and should be under the close attention of the doctor. Argumented approaches to the appointment of MHT in such patients will avoid complications associated with estrogen deficiency after surgery, radiation with or without systemic (cytostatic) treatment methods.

This paper aims at finding the most dominant ideas about the marketing of healthcare systems highlighted in the mainstream literature, with a focus on Russia and Romania. To reach this goal, a systematic analysis of literature was conducted and various competitive advantages and disadvantages of the medical models that require special attention from the governments are considered. In this respect we examined 106 papers published during 2006 to 2020 found on four scientific databases. They were selected using inclusion and exclusion criteria according to PRISMA methodology. The main findings of the research consist of the opportunity to use marketing tools in order to improve the quality of healthcare systems in the named countries. Thus, using market orientation, the managers of healthcare systems could stimulate the innovation, the efficiency of funds allocation and the quality of medical services. The results will lead to a better quality of population life and to an increasing of life expectancy. As this paper reviews some articles from Russian literature, it can add a new perspective to the topic. These outcomes have implications for government, business environment, and academia, which should cooperate in order to develop the healthcare system using marketing strategies.

AbstractIn this study, we focus on a specific form of metacommunication found in an emerging digital genre: Hotel reviews posted on TripAdvisor. In particular, we investigate how tourists represent their service encounter interactions. The main goal of the present study is to identify what these digital metacommunicative practices reveal about communicative norms and expectations among groups of reviewers writing in three different languages. We analyzed a multilingual dataset of 1800 reviews written in English, Dutch, and Italian. The results reveal that reviewers commented upon a broad range of aspects when evaluating service encounters interactions, for instance, describing the quality of the interaction (e.g. polite, correct), or a lack of communication when a specific type of communication is expected (e.g. absence of greetings, or apologies after a service failure). Further, we found similar cross-linguistic patterns, such as appreciation for being able to communicate in one’s mother tongue during the hotel-guest encounter. At the same time, a few differences across languages emerged, such as the preference for precise and correct information within British reviews. Since service interactions are of fundamental importance for customer satisfaction, our findings contribute not only to the current research on metacommunication in digital contexts, but may also be significant for service providers in the hospitality industry.

Critical limb ischemia (CLI) represents the most advanced stage of peripheral arterial obstructive disease (PAOD) with a severe obstruction of the arteries which markedly reduces blood flow to the extremities and has progressed to the point of severe rest pain and/or even tissue loss. Recent therapeutic strategies have focused on restoring this balance in favor of tissue survival using exogenous molecular and cellular agents to promote regeneration of the vasculature. These are based on stimulation of angiogenesis by extracellular and cellular components. This review article carries out a systematic analysis of the most recent scientific literature on the application of stem cells in patients with CLI. The results obtained from the detailed analysis of the recent literature data have confirmed the beneficial role of cell therapy in reducing the rate of major amputations in patients with CLI and improving their quality of life.

The inventory system is a system that has a very important role in a company. Inventory systems have been widely used or developed in a place with various technologies and systems. Problems at PT. Sanghiang Perkasa is due to the fact that the data has not been stored in a good file and the management and processing of inventory data is still processed in a conventional way, which has a very significant effect on the quality of the data and information produced. The main objective of this research is to produce an inventory system that is powerful and in accordance with the needs of the users associated with the inventory system. The system development method in this inventory system uses the waterfall method which consists of six stages. The stages are System Analysis and Design, software requirements analysis, system design, coding, system testing and maintenance. This system was built using the PHP programming language, DataBase MySQL. It is hoped that with the implementation of this inventory system at PT. Sanghiang Perkasa can make it easier to store and process data and information such as stock-taking data, information on incoming and outgoing goods transactions, purchase and sales return data, managing customer and supplier data to making product stock reports and assembly reports.

Abstract AIM Despite a wide variety of models found in literature, choosing the right one can be difficult as many of them are lacking precise methodology. This study aims to analyze and compare original burn models in terms of burn device and technique, parameters, and wound depth assessment. METHODS A systematic search was performed according to PRISMA guidelines on studies describing original experimental burn models in rats. The adapted PICO formula and ARRIVE checklist were followed for inclusion and assessment of quality of studies. Characteristics of animals, burn technique, burn parameters and method of histological confirmation of burn depth were recorded. RESULTS Twenty-seven studies were included in the final analysis. Most studies used direct contact with skin for burn infliction (n=20). The rat’s dorsum was the most common site (n=18). Ten studies used manually controlled burn devices, while ten designed automatic burn devices with control over temperature (n=10), exposure time (n=5), and pressure (n=5). Most studies (n=7) used a single biopsy taken from the center of the wound to confirm burn depth immediately after burn infliction. CONCLUSION From the wide variety of burn models in current literature, our study provides an overview of the most relevant experimental burn models in rats aiding researchers to understand what needs to be addressed when designing their burn protocol. Models cannot be compared as burn parameters variate significantly. Assessment of burn depth should be done in a standardized, sequential fashion in future burn studies to increase reproducibility.

Groundwater samples were collected in Erode city, Tamilnadu, from an area having large number of textile dyeing units. Though people residing in this area use river water supplied by local bodies as their major source for drinking, groundwater is also used as complementary source. The samples collected were subjected to systematic analysis using the standard methods and procedures. The values obtained for different physicochemical parameters were compared with the standard values given by ISI/ WHO. Variations in many physicochemical parameters were observed for most of the samples when compared to the standard values. More than half of the samples collected had their EC, TDS, total hardness, calcium, magnesium, sulphate and chloride exceeding their acceptable limits. This attempt has been made to determine the quality of groundwater in the study area confirms the deterioration of groundwater quality in the area and calls for some effective measures to be taken urgently to minimize the adverse impacts that may occur due to the contamination of groundwater.

AbstractHuman whole exome sequencing (WES) is now the standard for most medical genetics applications worldwide. The leaders are manufacturers of enrichment kits that base their protocols on a hybridization approach using cRNA or cDNA biotinylated samples specific to regions of interest in the genome. Recently, platforms from the Chinese company MGI Tech have been successfully promoted in the markets of many countries in Europe and Asia. There is no longer any question about their reliability and the quality of the data obtained. However, very few task-specific kits for WES, in particular, are presented for these sequencers. We have developed our solution for library pre-capture pooling and exome enrichment using Agilent probes. In this work, we demonstrate on a set of standard benchmark samples from the Platinum Genome Collection that our protocol, called “RSMU_exome”, is superior to the kit from MGI Tech in qualitative and quantitative terms. It allows detecting more SNVs and CNVs with superior sensitivity and specificity values, generates fewer PCR duplicates, allows more samples to be pooled in a single enrichment, and requires less raw data to produce results comparable to the MGI Tech solution. Also, our protocol is significantly cheaper than the kit from the Chinese manufacturer.
