The goal of the study was a spatial analysis of the morbidity of hearing loss of various types in the adult population of Chelyabinsk Region and the dependence of the incidence on the environmental issues at the place of residence. The epidemiological issues of the localization of hearing disorders were studied by spatial analysis in the R software environment. The main tasks of the spatial analysis were to produce a visualization, in the form of a point pattern, of the geographical coordinates of the patients’ places of residence, evaluate the properties of the spatial process that generates the point pattern, and test the hypothesis about the influence of the environmental situation on the indicator. The existing division into zones with different environmental situations, in general, does not have a statistically significant (p<0.05) effect on the ratio of the number of patients with hearing loss to the population of the district. However, statistically significant differences (p<0.05) of this indicator were found between areas with a critical and severe environmental situation, as well as between those with a critical and provisionally satisfactory situation. No statistically significant differences were found between the other regions (p>0.05).

The aim of the study is a spatial and statistical analysis of hearing loss of various types (conductive, sensorineural, mixed) and deafness in the adult population of the Chelyabinsk region, assessment of its dynamics and the impact of environmental stress in the place of residence. The study materials were data from the regional audiological center of the Chelyabinsk regional clinical hospital for the period from 2016–2020. Epidemiological issues of the spread of diseases were studied using the methods of spatial analysis, in the R software environment. The main tasks of spatial analysis were to visualize a point pattern from the geographical coordinates of the patient’s places of residence, assess the properties of the spatial process that generates this point pattern, test the hypothesis about the spatial randomness of this process and the influence of the ecological situation on it. It was found that more than half of all primary visits were patients with bilateral sensorineural hearing loss. The number of patients who applied for the year during the observation period fluctuates within the average. Of all hearing impairments, the highest values of relative incidence are characteristic of sensorineural hearing loss, which has a direct relationship with age. The intensity of detection in patients with hearing impairment and deafness is directly related to the size of the living population. The existing division into zones with different ecological situations does not have a statistically significant (p <0.05) effect on the ratio of the number of patients with hearing impairments to the population.

The identification of risk factors, features and patterns of the emergence and spread of diseases in space requires a large array of diverse data and the use of a serious mathematical and statistical apparatus. The distribution of diseases in space is studied using spatial analysis tools, which are now widely used as information systems are introduced and data are accumulated that are relevant to public health. For most tasks of working with spatial data (data, events that have geographical, spatial coordinates), various geographic information systems are used. As a disease for spatial analysis, sensorineural hearing loss was chosen, with which patients were treated at the Saint-Petersburg Research of Ear, Throat, Nose and Speech during one year of the study. The main tasks of the spatial analysis of data on the incidence of sensorineural hearing loss (SNHL) for hospitalization were: visualization of a point pattern, which can form the geographical coordinates of the places of residence of inpatients with SNHL; assessment of the properties of the spatial process that generates this point image (assessment of the intensity of the process, its laws) using various statistical indicators; testing the hypothesis about the spatial randomness of this process and the influence of individual factors on it. R-code accompanied all calculations in the article. Calculations can be reproduced quite easily. The text of the article can be used as step-by-step instructions for their implementation.

Computerized auditory training (CAT) is a convenient, low-cost approach to improving communication of individuals with hearing loss or other communicative disorders. A number of CAT programs are being marketed to patients and audiologists. The present literature review is an examination of evidence for the effectiveness of CAT in improving speech perception in adults with hearing impairments. Six current CAT programs, used in 9 published studies, were reviewed. In all 9 studies, some benefit of CAT for speech perception was demonstrated. Although these results are encouraging, the overall quality of available evidence remains low, and many programs currently on the market have not yet been evaluated. Thus, caution is needed when selecting CAT programs for specific patients. It is hoped that future researchers will (a) examine a greater number of CAT programs using more rigorous experimental designs, (b) determine which program features and training regimens are most effective, and (c) indicate which patients may benefit from CAT the most.

Chronic suppurative otitis media is one of the common otological conditions in India for which patients seek advice from an otorhinolaryngologist. Chronic suppurative otitis media is recurrent and progressive disease which is characterized with tympanic membrane perforation and suppurative discharge. Pure tone audiometry is the most common test used to evaluate auditory sensitivity. Since hearing loss is a common complication of chronic suppurative otitis media, we designed this study to evaluate preoperative pure tone audiometry findings in patients with chronic suppurative otitis media and its correlation with the intra-operative findings. <strong>Aims and Objectives:</strong> 1] To assess the intra-operative findings in patients with chronic suppurative otitis media. 2] To evaluate the correlation between the preoperative pure tone audiometry findings and intra-operative findings in patients with chronic suppurative otitis media. 3] To assess the type of hearing loss and degree of hearing loss in patients with chronic suppurative otitis media. <strong>Materials and Methods:</strong> This is an Observational study carried over a period of 3 years from August 2011 to August 2013. Total number of patients included in this study was 100. <strong>Result:</strong> Out of 100 patients studied 69 % of patients had Tubo-Tympanic type of CSOM, 31 % of patients had Attico-antral type of CSOM. In patients of Safe CSOM; Central perforation was seen in maximum cases 46.4 %, anterior central perforations was seen in 8.7 % cases, posterior central perforations seen in 20.2 % cases, and subtotal perforations seen in 24.63 % cases. In patients of Unsafe CSOM posterosuperior cholesteatoma was seen in maximum cases 67.74 %, and attic cholesteatoma was seen in 32.2 % cases. In safe CSOM patients all ossicles were intact and mobile whereas in unsafe CSOM patients only 4 patients had intact ossicular chain, while maximum patients had ossicular defect. <strong>Conclusion:</strong> Hearing loss depends on size of perforation. Hearing loss increases as the size of perforation increases. Average air conduction threshold and air bone gap did not differ significantly between various groups of ossicular defect. This shows us that neither air conduction nor air bone gap are reliable parameters on basis of which we can predict ossicular status preoperatively.

During the last several decades, cochlear implant has been fully recognized in treatment of severe hearing loss. Development of modern technology enabled inconceivable possibilities of technical qualities of the device as well as development of usable coding strategies, which led to extraordinary results in patient rehabilitation. Although cochlear implantation has become one of the routine operative procedures throughout the world nowadays, it gives rise to certain complications. These complications, though rare, can sometimes be very serious, even with fatal outcome. If cochlear implantation is performed by experienced and well-educated team of experts, the possibility of complications is minimal and is certainly not the argument against cochlear implantation as a method of treatment of severe hearing impairments.

Nowadays, approximately 5.8% in adult population around the world are suffering by diabetes. It can be caused by an increase in risk factors such as being overweight. Also it has been estimated that the number of patients will be doubled in near future and the demands for insulin hormone will be growing up by 3 to 4 % annually. Therefore, it?s necessary to develop new methods for hormone production with high rate of capacity in future. By advanced technology of transgenic DNA, the transgenic plants are introduced as an attractive system for expression and production of many kinds of pharmaceutical proteins. In this study, we investigated transfer of Human Proinsulin Gene into the Cucumber (Cucumissativus L.). Transgenic cucumber could be a great prospect for future source of eatable insulin pharmaceutical drugs to be taken by patients.Agrobacterium tumefaciensstrain LBA4404 carrying proinsulin genes with CaMV 35S promoter was used for the transformation purpose. The transgenic plants were analyzed by PCR, RT-PCR, SDS-PAGE, Dot blot and Electrochemiluminescence techniques. Production of proinsulin in cucumber could be a great prospect in molecular farming of human proinsulin.

The study uses data from state and industry official statistics for 2008-2017. Absolute and relative indicators of morbidity and prevalence of chronic cystitis among the female population of Ukraine, its regions and areas were analyzed taking into account two five-year periods for comparative assessment of the nature and intensity of dynamic processes. It is revealed that the number of patients with chronic cystitis (СC) registered in Ukraine is at the expense of women, which are 3-3.5 times more in number than men, with their characteristic more intensive growth (for 10 years by 3.6% against 0.4% among the adult population in the country). The first three places in the structure belong to the Southeastern region, Kyiv, Western region, the next – Central, Southern, Northeastern regions. Levels of the prevalence of the disease among women (100 thousand) are higher than the average in Ukraine and have a high growth rate (for 10 years by 13.5% from 232.2 to 263.6 against 9.3% from 171.5 to 187.5, respectively). Typical for Ukraine persistent increase in patients with the first diagnosis of chronic cystitis (0.8%, 2.1% and 2.8%, respectively, in the first, second periods and 10 years to 15112 in 2017) is also formed by this category (women's growth was 3.4%, 12.4%, and 5.0%, respectively, to 11.295). A similar situation was also identified in the analysis of the level of morbidity (per 100 thousand). In Ukraine, its growth rate for the last five years was 9.6% against 1.8% for the previous year, for 10 years – 11.9%, and the value reached 43.4 in 2017 against 38.8 in 2008. Among women, its levels are higher than the average in Ukraine (in 2017 – 59.2 against 56.1 in 2008), and the increase was more intense (by 6.2% and 11.3% over the periods; for 10 years – by 11.98%).

Hearing loss is highly prevalent and increases as a function of age. Although hearing loss affects many aspects of ageing and communication, it is often overlooked and treated as a rather inconsequential side effect of ageing. The purpose of this chapter is to introduce age-related hearing loss, the broader implications of age-related hearing loss as it relates to healthy ageing, and practical strategies for primary care management of hearing loss. A majority of the cases of age-related hearing loss remain untreated. Primary and/or geriatric care clinics may serve as the entry point for many older adults with hearing loss. Including questions about hearing loss or screening for hearing loss at other health encounters may increase access for older adults to hearing loss treatment.

Abstract BACKGROUND Heart failure (HF) remains one of the major cardiovascular challenges to the Western world. Once established, HF is characterized by compromised life expectancy and quality of life with considerable dependence on hospital care for episodic clinical deterioration. Much is understood about the risk factors that predispose to the development of HF. With such a broad range of factors, it is clear that there is a large population at risk, potentially in excess of 25% of the adult population. Therein lies the major challenge at the outset of our efforts to prevent HF. With such a large population at risk, how do we develop an effective prevention strategy? CONTENT HF prevention requires a multimodal approach. In this review, we focus primarily on the role of natriuretic peptide (NP) as a tool in a prevention strategy. SUMMARY Prevention of HF is a major public health challenge, underlined by the concerning epidemiological trends, the associated costs, and the continued difficulty to find effective therapies for the growing number of patients with preserved systolic function HF. Population-based approaches focusing on lifestyle and risk factor control have made some impact but not to a satisfactory level and also tend to result in a uniform approach across a population with different risk profiles. Individualizing risk is therefore required, with emerging data indicating that NP-guided risk stratification and intervention can reduce downstream incident HF and other cardiovascular events.

Audiologists and acoustical engineers have urged that acoustics be considered in the design of classrooms for more than 30 years. Research has demonstrated that children with hearing loss have great difficulty understanding speech in noisy, reverberant environments. However, there has never been a legal mechanism to require local educational systems to address acoustics in the design and construction of schools. An effort by a broad-based coalition of engineers, audiologists, parents, architects, and educators is now underway to develop a standard for acoustics that would then be referenced in the Americans with Disabilities Act (ADA). Although the legal mechanism for this action is to address the needs of children with disabilities as the ADA requires (most notably, children with hearing impairments, but also those with central auditory disorders, attention deficit disorders, and vision impairments), the impact will be more far-reaching. All children—whether or not they have a disability—will benefit from a favorable acoustical environment.
