Associations between sampling characteristics, nutritional supplemental taking and the SARS-CoV-2 infection onset in a cohort of Italian nurses
Authors: Vitale Elsa , Mea Rocco
Published: January 2023

Background: The aim of the present study was to analyze any relations existed between sampling characteristics and the onset of the SARS-CoV-2 infection, also by considering the number of times that it occurred in a cohort of Italian nurses interviewed. Additionally, by considering the nutritional supplemental taking, this research wanted to assess any differences both in the onset and in the number of times which the infection occurred among participants. Method: An observational cohort study was carried out thorough all Italian nurses by advertising the questionnaire through some professional internet pages. Results: Work typology (p=0.021), ward Covid-19 (p=0.002) and regular meal assumption (p=0.019) significantly associated to the onset of the SARS-CoV-2 infection. Most of nurses who contracted the SARS-CoV-2 infection worked during the night shift (53.7%), 44.3% worked in a no-Covid-19 ward and 53% declared to have a regular meals’ assumption. Ward typology significantly associated to the times of the SARS-CoV-2 onset (p=0.003), as most of nurses who contracted almost one time the SARS-CoV-2 infection were employed in a no-Covid-19 ward (55.5%) and 54.1% of them declared to have a regular meals’ assumption. The onset of the Sars-CoV-2 infection seemed to be more present in the most part of the sample collect. Conclusion: The present study could be considered as pilot in this sense and also more studies will be performed in order to better relate the function of supplemental food intakes with a better functioning of the immune system.

Background: Both of chronic inflammation and mineral disturbance are major concerns in patients with chronic kidney disease, particularly end-stage renal disease (ESRD). Objectives: The present study aimed to investigate the association between circulating IL-6 and minerals dysregulation in patients diagnosed with ESRF and on a continuous hemodialysis regimen. Methods: This cross-sectional study included 74 patients undergoing continuous hemodialysis. Serum samples were tested for IL-6 using an enzyme-linked immunosorbent assay. Mineral were analyzed using an electrolyte analyzer and biochemical tests. Parameter correlations were analyzed using the Pearson’s correlation test. Results: Among the studies group, the male: female ratio was 1:0.72. IL-6 mean value was 13.77 pg/ml ±9.79 SD. IL-6 was significantly negatively correlated with circulating iron and calcium levels (r= - 0.229, P= 0.049; r= -0.252, P= 0.03, respectively). IL-6 was significantly positively correlated with K+ levels (r= 0.269,P= 0.02). Conclusion: The present study highlighted the substantial role of IL-6 in mineral dysregulation in hemodialysis patients, highlighting this cytokine as a potential therapeutic target for minimizing and monitoring the clinical effects of mineral disturbances, including cardiovascular and neurological complications.

Authors: Hawkinson Lauren E. , Yates Lindsey , Minnig Mary Catherine , Register-Mihalik Johna K. , Golightly Yvonne M. , Padua Darin A.
Published: January 2023

Objective

To systematically review and summarize the knowledge, attitudes, beliefs, and contextual perceptions of youth sport coaches toward injury-prevention training programs by using the Theoretical Domains Framework to guide the organization of results.

Data Sources

Systematic searches of PubMed and Google Scholar were undertaken in November 2021.

Study Selection

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol was followed. Results were limited to full-text articles that were published in peer-reviewed journals and printed in English. Additional studies were added after a citation search of included studies. Studies were eligible for inclusion if researchers evaluated youth sport coaches' knowledge, beliefs, contextual perceptions, or all 3 of anterior cruciate ligament injury-prevention training programs.

Data Extraction

Data charting was performed by 1 author and confirmed by a separate author.

Data Synthesis

Of the 1194 articles identified, 19 were included in the final sample. Among articles in which researchers assessed knowledge (n = 19), coaches' awareness of the existence and components of injury-prevention training programs was inconsistent. Among articles in which researchers assessed beliefs (n = 19), many coaches had positive attitudes toward injury-prevention training programs, but few believed youth athletes are at a high risk of injury. Among articles in which researchers assessed contextual perceptions (n = 13), many coaches did not feel they had access to information about injury-prevention training programs and cited a lack of time, space, support, and other resources as barriers to implementation.

Conclusions

Our findings support the need for programs, protocols, and policies to enhance knowledge of and support for youth sport coaches who wish to implement injury-prevention training programs. A gap exists in the research about addressing the needs of youth sport coaches in the United States high school sports setting. The use of multilevel implementation science frameworks (such as the Theoretical Domains Framework) will be beneficial for identifying constructs that affect implementation and developing train-the-trainer programming to meet the needs of individual youth sport coaches.
Return-to-Sport Criteria After Anterior Cruciate Ligament Reconstruction Fail to Identify the Risk of Second Anterior Cruciate Ligament Injury
Authors: Paterno Mark V. , Rauh Mitchell J. , Thomas Staci , Hewett Timothy E. , Schmitt Laura C.
Published: January 2023

Background

The incidence of second anterior cruciate ligament (ACL) injury after ACL reconstruction (ACLR) is high in young, active populations. Failure to successfully meet return-to-sport (RTS) criteria may identify adult athletes at risk of future injury; however, these studies have yet to assess skeletally mature adolescent athletes.

Objective

To determine if failure to meet RTS criteria would identify adolescent and young adult athletes at risk for future ACL injury after ACLR and RTS. The tested hypothesis was that the risk of a second ACL injury after RTS would be lower in participants who met all RTS criteria compared with those who failed to meet all criteria before RTS.

Design

Prospective case-cohort (prognosis) study.

Setting

Laboratory.

Patients or Other Participants

A total of 159 individuals (age = 17.2 ± 2.6 years, males = 47, females = 112).

Main Outcome Measure(s)

Participants completed an RTS assessment (quadriceps strength, functional hop tests) and the International Knee Documentation Committee patient survey (0 to 100 scale) after ACLR and were then tracked for occurrence of a second ACL tear. Athletes were classified into groups that passed all 6 RTS tests at a criterion level of 90% (or 90 of 100) limb symmetry and were compared with those who failed to meet all criteria. Crude odds ratios and 95% CIs were calculated to determine if passing all 6 RTS measures resulted in a reduced risk of second ACL injury in the first 24 months after RTS.

Results

Thirty-five (22%) of the participants sustained a second ACL injury. At the time of RTS, 26% achieved ≥90 on all tests, and the remaining athletes scored less than 90 on at least 1 of the 6 assessments. The second ACL injury incidence did not differ between those who passed all RTS criteria (28.6%) and those who failed at least 1 criterion (19.7%, P = .23). Subgroup analysis by graft type also indicated no differences between groups (P > .05).

Conclusions

Current RTS criteria at a 90% threshold did not identify active skeletally mature adolescent and young adult athletes at high risk for second ACL injury.
Liver metastasis of breast carcinoma: An unusual presentation and growth pattern
Authors: Özşen Mine , Uğraş Nesrin , Yerci Ömer , Deligönül Adem
Published: January 2023

Breast carcinoma is one of the tumors that frequently metastasize to the liver. Extramedullary hematopoiesis (EMH) usually occurs due to insufficient medullary hematopoiesis. In this case report, we present a female patient with sinusoidal breast carcinoma metastasis and extramedullary hematopoiesis in liver biopsy. A 63-year-old female patient with history of breast carcinoma was admitted to our center with respiratory distress. Pleural effusion was detected and thoracentesis was planned. Treatment was given after detection of non-mycobacterial tuberculosis bacillus in the thoracentesis fluid. Antibiotherapy was terminated due to elevation of liver enzymes and bilirubin. The patient’s clinical status was evaluated and treatment was re-initiated. The patient did not have any mass lesion in the liver. Tru-cut biopsy was performed to evaluate a possible tuberculosis involvement in the liver. The diagnosis of metastatic breast carcinoma located in the sinusoidal area and cholestatic liver with extramedullary hematopoiesis foci was given using the histomorphological, immunohistochemical and histochemical findings. Radiological evaluation has an important role in staging of malignancies. However, it should be kept in mind that hepatic metastases may present without formation of a mass lesion, and unexpected laboratory results of cases without abnormal radiological features should raise the suspicion of a metastasis. Such materials should be evaluated in detail by making multiple serial sections in the pathology laboratory. Rare metastatic tumor growth patterns not causing a mass lesion such as sinusoidal or portal pattern, should also be kept in mind.

A Study of Impulsivity, Compulsivity, and Dysfunctional Belief among Medical Undergraduate Students with Problematic Internet Use
Authors: Abhilasha Pallavi , Haryal Aneesha , Malhotra Meha , Reddy Mrinalini , Moorthy Thenmozhi , Singla Mamta
Published: January 2023

Background:

Internet addiction has been described as an emerging behavior related to the development of new technologies. Impulsivity is a risk factor for addictive behaviors. Maladaptive use of the Internet has been coined as compulsive Internet use. Dysfunctional belief is an irrational thinking pattern where there is a negative view of self, the outer world, and future.

Aim:

The present study aims to assess the role of impulsivity, compulsivity, and dysfunctional belief leading to problematic Internet use.

Materials and Methods:

A total of 300 undergraduate medical students were assessed on this cross-sectional scale. Demographic details, Internet Addiction Test, Urgency Perseveration Premediation Sensation Seeking Positive Urgency Scale, Compulsive Internet Use Scale, and Dysfunctional Attitude Scale were filled by the participants using Google Forms. One hundred students could not be assessed due to nonresponse.

Results:

This study had a response rate of 66.6%, and of the respondents, 74.4% were mild, 25.2% were moderate, and 0.76% were severe in nature. A positive correlation was observed between Internet addiction and compulsive Internet use. There was a positive correlation between Internet addiction and lack of perseverance and positive urgency. There is an overall significance between level of dependency, achievement, and self-control in problematic and nonproblematic users.

Conclusions:

In the emerging era of Internet use, we must learn to differentiate excessive Internet use from addiction and be vigilant about psychopathology.

Locally finitely presented and coherent hearts

Published: January 2023

Starting with a Grothendieck category

\mathcal{G}

and a torsion pair

\mathbf{t}=(\mathcal{T},\mathcal{F})

in

\mathcal{G}

, we study the local finite presentability and local coherence of the heart

\mathcal{H}_{\mathbf{t}}

of the associated Happel–Reiten–Smalø

t

-structure in the derived category

\mathbf{D}(\mathcal{G})

. We start by showing that, in this general setting, the torsion pair

\mathbf{t}

is of finite type, if and only if it is quasi-cotilting, if and only if it is cosilting. We then proceed to study those

\mathbf{t}

for which

\mathcal{H}_{\mathbf{t}}

is locally finitely presented, obtaining a complete answer under some additional assumptions on the ground category

\mathcal{G}

, which are general enough to include all locally coherent Grothendieck categories, all categories of modules and several categories of quasi-coherent sheaves over schemes. The third problem that we tackle is that of local coherence. In this direction, we characterize those torsion pairs

\mathbf{t}=(\mathcal{T},\mathcal{F})

in a locally finitely presented

\mathcal{G}

for which

\mathcal{H}_{\mathbf{t}}

is locally coherent in two cases: when the tilted

t

-structure in

\mathcal{H}_{\mathbf{t}}

is assumed to restrict to finitely presented objects, and when

\mathcal{F}

is cogenerating. In the last part of the paper, we concentrate on the case when

\mathcal{G}

is a category of modules over a small preadditive category, giving several examples and obtaining very neat (new) characterizations in this more classical setting, underlying connections with the notion of an elementary cogenerator.
Supporting the Transition Out of the Family Caregiver Role: An Occupation-Centered Approach
Authors:   , Wilbanks Whitney
Published: January 2023

Engagement in meaningful and valued occupations can be used as a means to help former family caregivers cope, heal, and grow following the loss of their loved one (Pickens, 2011). Occupational engagement can be used as a means to help former family caregivers reshape their personal identity, experience a sense of wholeness, and reestablish purpose and balance in their lives (Hocking, 2016). The purpose of this doctoral capstone project was to educate hospice care staff on ways to support individuals with transitioning out of the family caregiver role following the death of the care recipient. An educational resource was developed to inform hospice care staff on the use of occupation-centered interventions and activities to foster adaptation to shifts in roles, routines, habits, and rituals after caregiving ends.
“It Even Makes the Animals Laugh"
Authors: Ingram Darcy
Published: January 2023

Henry Bergh founded and became president of the first animal protection organi- zation in the United States, the American Society for the Protection of Cruelty to Animals (ASPCA) in New York City in April 1866, the same month in which his ef- forts to secure modern animal welfare legislation at the state level—also a first—were realized. From then until his death in 1888, Bergh steered his organization and the movement through the streets, the slaughterhouses, the courts, and the halls of that city and the nation. As this article shows, his critics were never far behind. Through a combination of media reportage, annual reports, and correspondence, this article weighs the impact of satire and ridicule directed toward Bergh and the animal protec- tion movement alongside his efforts to reposition such coverage and in some cases to benefit from it. In doing so, it positions Bergh and the animal protection movement relative to issues of frame alignment, leadership, and performance in the context of a rapidly changing media landscape, the negotiation of which was central to the move- ment’s success or failure.
“For Your Freedom and Ours”
Authors: Palmer Tom
Published: January 2023

Across Western Europe the emergence of Poland’s Solidarność, the first independent trade union in a communist state, elicited varied responses. While the assistance pro- vided to Polish workers from continental European has been addressed, the solidar- ity effort in Britain is scarcely understood. Building on Stefan Berger and Norman LaPorte’s previous work, this article investigates the response of the British labour movement across the UK. While the British Left’s response is typically considered lukewarm, this article exposes the discrepancy between the efforts of rank-and-file labour activists and the leadership of key institutions. Drawing upon oral histories with contemporaneous activists, trade union archives, and prominent left-wing publi- cations, it is apparent that this distinction was present in the Trades Union Congress, large trade unions, and the Labour Party. Understanding British solidarity with So- lidarność ultimately elucidates the permeability of the Iron Curtain and contributes to an understanding of the role East-West socio-political interactions played in the demise of the Soviet Union.

Published: January 2023

On the example of a clinical case, we used software 3D modeling of the reconstruction of the shape of the skull of a child aged 2 years and 5 months with metopic craniosynostosis, as well as manual training using a craniotomy on an individual 3D model of the patient's skull before surgery. The use of a plastic 3D model of a particular patient made it possible to conduct a “trial, training operation” to work out the optimal osteotomy geometry. An intraoperative evaluation of the result obtained on a visual scanner was also carried out.

Purpose of the study. Improving the result of surgical treatment of a child with metopic craniosynostosis using preoperative 3D planning and personalized simulation of a planned operation. For the purpose of preoperative planning we used an algorithm with the inclusion of 3D technologies: preoperative modeling on software, simulation of surgery on plastic models of the skull, surgical intervention along craniotomy lines, intraoperative visual scanning and assessment of the results of skull reconstruction.

Conclusion. The preoperative 3D modeling of the skull formed a complete plan for individual reconstructive changes in the skull in our patient with metopic craniosynostosis over the age of two years, and allowed us to perform a “trial, training operation” on a plastic model to work out the optimal osteotomy geometry. This made it possible to provide the optimal technique for a real operation, speed up its implementation, reduce trauma and blood loss, the duration of anesthesia, and, in combination, improve the results of surgical treatment.

Published: January 2023

The study investigates the nexus between risk management and performance of Habib Bank Limited using the annual financial time series data from 2005 to 2021. The dependent variable is the bank performance measured by using return on equity. The independent variables are the financial risks, which include credit risk, liquidity risk, and operational risk. The findings suggest that the credit risk and liquidity risk negatively impact the performance of Habib Bank Limited, which means that the increase in credit risk and liquidity risk would result in declining the profitability of Habib Bank Limited. Moreover, operational risk has a significant positive effect on the bank's performance. The study concludes that Habib Bank Limited needs to control its credit and liquidity risks to perform well in the market. It is recommended that Habib Bank Limited adopt strict policies and do a risk analysis of each borrower before issuing the loan. Habib Bank Limited must offer attractive financial products to motivate the depositors to deposit more in the account to control the liquidity risk.

Published: January 2023

Vegetables are the most important source of nitrate in the human diet. The nitrate content is not the same in the plant. Depending on the amount of nitrites, plant organs can be classified as follows: leaf (the largest amount) stem, inflorescence root, tuber, fruit. One of the most important factors in determining the quality of vegetable products is the content of nitrates and nitrites and the maximum permitted limits play an important role in human health. It is well known that a high dietary intake of nitrates and nitrites may increase the risk of gastrointestinal cancer due to the formation of carcinogenic chemicals known as N-nitroso compounds and the appearance in newborns of blue child syndrome. This study assessed the concentrations of nitrates and nitrates in 5 varieties of tomatoes from organic and the same 5 varieties from classical crops. The study showed that the amount of nitrates and nitrites in the tomato varieties taken in the studio was within the limits according to the legislation in force.

Published: January 2023

Indonesia had become an oil exporter that is recognized by the world for many years and joined The Organization of Petroleum Export Community (OPEC) – an organization that controls petroleum production, supplies, and prices in the global market – in 1962. However, oil production in Indonesia has been decreasing from year to year, one of which is due to the lack of investment in the exploration of new oil wells in Indonesia so the majority of upstream oil and gas work in Indonesia is exploiting old wells which will naturally decline steadily. This resulted in Indonesia becoming a net import oil country in 2003. Therefore, additional operations are needed to maximize oil production from these existing wells, one of which is by conducting Chemical Enhanced Oil Recovery (CEOR). The main objective of EOR itself is to mobilize the remaining oil by enhancing the oil displacement and volumetric sweep efficiency. PT. ABC, a subsidiary of PT. XYZ (a state-owned company under SKK Migas and PT Pertamina supervision) which is engaged in the upstream sector in Indonesia, is assigned by the government to carry out one of the CEOR projects that have been determined by the Government. This research covers the economic feasibility of the CEOR Project based on the conventional Discounted Cash Flow (DCF) and Real Option Valuation (ROV) Model. The revenue-sharing policy used for the project economic calculation is the gross split method. The result of the economic analysis using the DCF method is the project is not economically feasible to run as the net present value (NPV) shows negative which is -2,911 MUSD. However, the real option valuation model helped increase the value to 11,416 MUSD by adopting a strategic option which is an option to delay and time flexibility into the project. As a result, the project could be economically feasible if the operation is deferred to the following year and the oil price is over 85.2 USD/BBL.

Published: January 2023

The technological developments, population growth and the food needs of the Indonesian people in consuming food. Online grocery stores are growing to meet people’s needs in the digital era. That is what makes INAGRI as an online grocery sales company continue to innovate in agriculture. Starting to change online shopping behavior can be a huge potential market, but INAGRI faces many people who don’t know the INAGRI brand as an online grocery store company, so INAGRI’s sales have not reached the target. Therefore, what factors influence someone to know brand awareness really needs to be known. To create a successful marketing strategy, companies must analyze business problems with internal and external environmental analysis. External environment analysis consisting of; PESTEL (Politics, Economics, Social and Technology, Environment, Law), Porter 5 strengths, competitor analysis and consumer analysis using questionnaires and internal focus analysis on the marketing mix known as the 4P marketing mix and STP (Segmenting, Targeting and Positioning). The root cause of the problem says that brand awareness is not high enough, so purchase intention is also not high enough. This research is a quantitative study using Partial Least Square-Structural Equation Model (PLS-SEM) data analysis with the help of Smart PLS 4.0 software. Primary data was obtained from distributing questionnaires to 220 respondents. The results of data processing show that the variables Sales promotion, advertising, brand interactivity have a positive effect on brand awareness. Only content quality has no effect, then brand awareness also has a positive effect on purchase intention. Recommended marketing strategy recommendations are Providing product promotions with brand interactivity and creative advertising, collaborating with influencers, optimizing and making Video TikTok and Instagram sales marketing through social media, participating in marketing events to increase brand awareness and improve the quality of human resources by attending training digital marketing for INAGRI employees.

While the number of universities in Vietnam has increased dramatically over the past decade, the country's poor quality of higher education has received much attention in recent times. The increasing number of university graduates without jobs and the number of university lecturers switching to other jobs is attracting many studies to find the causes, including public service motivation, job satisfaction, and teaching performance of university lecturers. This study aims to enrich the research literature and examine the role of service motivation as a moderator variable in the relationship between job satisfaction and teaching effectiveness of Vietnamese university lecturers. This study was conducted through a cross-sectional survey using a purposive sampling technique (n=200). Multivariable linear regression analysis and moderator regression were applied to test the proposed research hypotheses. Research results show a positive and significant relationship between satisfaction at work, motivation to serve the public, and teaching effectiveness of Vietnamese university teaching. In particular, public service motivation moderates the relationship between job satisfaction and the teaching performance of university lecturers in this country.

This study uses the research object of insurance companies in the ASEAN region. Insurance companies are overgrowing. This issue happened because Southeast Asia is one of the regions with the fastest development globally over the last 10 years. The use of insurance services in the Southeast Asia Region reached 3.77%. This percentage reflects that half of the use of services in the Southeast Asia Region represents half the use of insurance globally. The population in this study is Insurance Service Companies in the ASEAN Region. In contrast, the sample in this study is Insurance Service Companies in the ASEAN Region that are listed on the Stock Exchange in each country in the 2017-2019 period. Partially, net premium growth has a positive effect on financial performance, and claim ratios, risk-based capital, and retention ratios do not affect financial performance.

Objective: To compare the effect of intra-cuff lidocaine versus alkalinized lidocaine in the prevention of post-operative sore throat.
Method: The cross-sectional study was conducted from June 15 to July 15, 2019, at the Department of Anaesthesiology, Liaquat National Hospital and Medical College, Karachi, and comprised patients of either gender aged 15-50 years classified as American Society of Anaesthesiologist class 1-2 and going under general anaesthesia with endotracheal intubation expected to last more than one hour. The patients were randomised into Group L and Group LA.  General anaesthesia was given using induction dose of propofol 2-3mg/kg, nalbuphine 0.1mg/kg and atracurium 0.5mg/kg and female patients were intubated with 7.0mm size endotracheal tube and males patients with 8.0mm. All intubations were performed by an anaesthesiologist with minimum of two-year experience. The endotracheal tube cuff was inflated by using plain lidocaine 2% in group L and 2% lidocaine with 8.4% sodium bicarbonate in LA group till the air leak diminished. Post-surgery, the patients were assessed on extubation for any emergence phenomenon and were re-assessed at 1st, 6th, 12th and 24th hour. The assessment was done by the on-call anaesthesiology resident who was blinded to the study group. Data was collected using a proforma. The analysis was done using software IBM SPSS Statistics 23.0. Chi-Square Test was applied to analyse the data.
Results: Of the 58 patients, 33(56.9%) were male and 25(43.1%) were female. There were 26(44.8%) patients aged 25-36 years, while 12(20.7%) each were aged 36-45 years and 46-55 years. There were 29(50%) patients in each of the 2 groups. After 24 hours, 75.9% patients in Group L did not complain of any pain, while in group LA the corresponding number was 96.6%. Both in terms of cough and hoarseness at 24 hours, 96.6% patients in Group L did not have complaints, while in Group LA there were no such complaints. In Group L, heart rate 60-80 was noted in 20(69%) patients and 81-100 in 9(31%).  In Group LA, the corresponding values were 17(58.6%) and 12(41.4%).
Conclusion: Alkalinized lidocaine was found to be highly effective in preventing post-operative throat complications compared to lidocaine.
Key Words: Alkalanized lidocaine, Hoarseness, Intra-cuff lidocaine, Sore throat.
International experience of air pollution assessment in areas where enterprises with odorous emissions are located (literature review)

The article provides a review of literature data on approaches to the ambient air pollution assessment in the areas where enterprises - sources of odour are located. According to the analysis, international practice in the field of odour management in the atmosphere includes a variety of methods of the odour impact assessing. The considered approaches, both predictive and observational (empirical), have their advantages and disadvantages. Thus, atmospheric dispersion modelling is a very valuable predictive tool and plays an important role in assessing ambient odours. However, the models, although based on rigorous quantitative calculations, are a simplification of the real situation. The accuracy of this method is significantly reduced in cases of unpredictable, unplanned or accidental releases. An easier-to-use tool is a qualitative (descriptive) risk-based odour assessment (source-pathway-receptor concept). Empirical approaches (field olfactometry, sniff tests) make it possible to assess odour exposure in given real conditions, while more objective assessment requires long-term studies. The use of instrumental methods is limited by the fact that odours in the air are mainly due to complex multicomponent mixtures of substances with an unknown nature of the combined action, with levels below the detection limits, etc. When developing an odour assessment strategy, it is necessary to select the tools that are most appropriate in each case. According to many authors, to improve the quality and reliability of this assessment in areas where enterprises and other facilities are located, it is advisable to use all available empirical approaches together with modelling, in combination with community surveys and other methods of analyzing the health status of the population. The data obtained as a result of such a comprehensive assessment will make it possible to substantiate measures to reduce air pollution by odorous substances.

Introduction. An urgent hygienic problem in regions with intensive industrial development is inadequate air quality, which causes unacceptable risks of developing somatic diseases among the population in their places of permanent residence. The purpose of the study is to substantiate the associative relationships of indicators of negative effects on the respiratory organs and the blood system with an elevated blood content of copper, nickel and chromium in children. Materials and methods. A hygienic assessment of the quality of ambient air in residential buildings was carried out, the risk was assessed, chemical-analytical, biochemical, general clinical, immunological and proteomic studies and statistical analysis were performed. Results. Established associative relationships of increased blood levels of copper, nickel and chromium with a change in the indicators of negative effects. Markers of the formation of chronic inflammation, accompanied by an imbalance of cellular and humoral immunity, are a decrease in the phagocytic index and number, overproduction of copper-specific IgG, total IgG; markers of a possible violation of the cascade of enzymatic reactions of the plasma system of blood coagulation and vascular-platelet hemostasis is a decine in the expression of prothrombin, vitronectin and hemoglobin beta subunit; development of induction of oxidative processes including an increase in MDA in blood plasma. Limitations. The conducted study does not make it possible to draw unambiguous conclusions about the effect of the studied chemicals on changes in biochemical and hematological parameters,and as well as morbidity rates, since the possibility of the impact of other factors (heredity, gender and age characteristics) not studied in this work is not excluded. Conclusion. It is expedient to use the obtained results for the implementation of targeted measures to prevent negative consequences on the part of the respiratory system, the immune system, and the blood system, etiopathogenetically associated with the aerogenic combined effect of nickel, chromium and copper oxides.

The health is influenced by many factors including physical, psychological, emotional well-being, both social and economic viability of the child family. In addition, one of the key factors affecting the maintenance and promotion of health is a balanced diet. Adequate dieting is necessary for the normal physiological functioning of the child’s body, because due to the rapid growth and development, children are very prone to the deficiency of its various components. This issue is especially relevant for children studying in specialized schools. If the principles of a balanced diet are not observed, many symptoms of diseases, including psychoneurological ones, are aggravated and often cannot be corrected. According to the results of epidemiological studies conducted in different regions of Russia, significant violations in the nutrition of all school-age children were revealed. These include an irrational ratio of essential nutrients, excessive consumption of fat, added sugar and salt, insufficient content of polyunsaturated fatty acids, vitamins, macro- and microelements, dietary fiber, as well as disturbances in the regimen and management of nutrition. It is important to note that the described violations were found in schoolchildren of general education schools, while studies on the actual nutrition of children in correctional schools were not conducted. Conclusion. Despite a lot of research in the field of nutrition, there remains a need to study the structure of nutrition and nutritional status in children studying in correctional schools to scientifically substantiate and develop measures for the prevention and correction of alimentary-dependent diseases. The main directions of which should be monitoring the nutritional status of children in the following up their development, optimizing nutrition, taking into account the pathology of the child, the use of fortified foods and the appointment of vitamin-mineral complexes, with the aim of additional intake of necessary substances.
