Immediate results of combined coronary bypass surgery and aortic valve replacement with incomplete and complete myocardial revascularization
Authors: Litus V. S. , Gramatikov D. G. 
Published: October 2023

Introduction. Coronary heart disease and aortic valve stenosis still occupy a leading position among cardiovascular diseases. Against the background of an increase in life expectancy, patients with a combined pathology of the heart are increasingly appearing. Without surgical treatment, such patients have an unfavorable prognosis of life with a high mortality rate. Simultaneous surgical correction of coronary heart disease and aortic valve stenosis is a treatment method that can improve the prognosis and prolong the life of a patient. At the same time, combined interventions remain higher-risk operations compared to isolated aortic valve replacement and isolated coronary artery bypass grafting.The Objective was to evaluate the effect of incomplete and complete myocardial revascularization on the immediate results of surgical correction of combined pathology of the aortic valve and coronary arteries.Methods and Materials. For the period from 2017 until June 2022, 62 aortic valve replacement operations in combination with coronary artery bypass grafting were performed in the cardiac surgery department of the Leningrad Regional Clinical Hospital. The operated patients were divided into two groups. The group 1 included (n=32) patients who underwent aortic valve replacement and complete myocardial revascularization. The group 2 included patients (n=30) who underwent aortic valve replacement and incomplete myocardial revascularization.Results. Postoperative periods in both groups, according to the structure of early postoperative complications, are generally similar. The mortality rate in both groups did not exceed the predicted mortality rate and corresponded to the data of various literary sources.Conclusion. Our observation data showed that the mortality rate in the early postoperative period, in combined operations, does not depend on the completeness of revascularization in combined operations of coronary artery bypass grafting and aortic valve replacement. It is necessary to perform as complete myocardial revascularization in combined operations as technically feasible and appropriate in a clinical situation.

Introduction. Contrast-induced nephropathy (CIN) is a complication that occurs after contrast medium (CM) administration. The existing risk scales for possible CIN include chronic kidney disease and do not take into account stenotic changes in the renal artery with normal serum creatinine levels.The Objective was to study the frequency of CIN in patients with acute and chronic coronary occlusion (CCO) after endovascular recanalization in the presence of hemodynamically significant renal artery damage with initially normal creatinine levels.Methods and Materials. The study included 38 patients with acute coronary syndrome (control group) and 67 patients with CCO and hemodynamically significant renal artery stenosis (main group). Stenting of one of the renal arteries was performed in 25 patients out of 67 patients before planned coronary revascularization.Results. The incidences of CIN were significantly higher than the calculated one in patients with CCO and renal artery stenosis. In the group of patients with pre-stenting of the renal arteries, there was a decrease in cases of CIN.Conclusions. Renal artery stenosis with normal creatinine levels is an additional risk factor for CIN.

Published: October 2023

Sebagian besar aktivitas di pasar akan menghasilkan air limbah. Air limbah di pasar biasanya berasal dari kios penjualan daging dan ikan karena banyak menggunakan air untuk mencuci. Selain itu, air limbah juga banyak dihasilkan dari kegiatan MCK. Kurangnya perhatian akan pengelolaan limbah cair pasar mengakibatkan limbah cair pasar yang dialirkan belum memenuhi persyaratan kualitas limbah cair karena terjadi kontaminasi mikrobiologi di dalamnya. Penelitian ini menilai bagaimana kondisi sanitasi dari beberapa pasar tradisional di Pontianak, yakni Pasar Flamboyan, Pasar Dahlia, Pasar Teratai, dan Pasar Kemuning sesuai Permenkes RI No.17 Tahun 2020. Kondisi sanitasi kemudian dikaitkan dengan jumlah bakteri E. coli dalam limbah cair pada masing-masing pasar yang telah diuji dengan metode MPN, di mana kehadiran bakteri ini sebagai parameter mikrobiologi penanda hadirnya patogen. Hasil penilaian kondisi sanitasi menunjukkan hanya Pasar Kemuning yang memenuhi syarat sebagai Pasar Sehat sesuai Permenkes RI No.17 Tahun 2020 dengan persentase sebesar 75,3%. Selain itu, hasil uji statistik bivariat menunjukkan bahwa terdapat korelasi yang kuat antara kondisi sanitasi pasar dengan keberadaan bakteri Escherichia coli pada limbah cair. Semakin baik kondisi sanitasi pasar, maka semakin baik juga kualitas mikrobiologi pada limbah cair di setiap pasar.

Authors: KUŞKU ÖZDEMİR Emel 
Published: October 2023

This study was conducted with the aim of revealing employees' perception of competence and determining which competence domains and sub-components are most associated with competence. Adopting a qualitative research approach, the study was designed using a phenomenological pattern, and research data were collected through an in-depth interview method. The research findings were interpreted based on the responses provided by private sector employees to questions in line with their professional experiences, focusing on their perceptions of professional competence and the types of competencies they highlight as crucial for success in today's competitive business environment.
According to the findings, the perception of competence among private sector employees is categorized into three main themes, namely technical/functional, fundamental/managerial, and behavioral/personal, which align with the literature. The most significant research finding obtained within the scope of this study is the participants' emphasis on communication competence as the most crucial type of competence in today's context. Additionally, participants have further delineated sub-themes of communication competence by discussing various types of communication competencies within the realm of work life. Among all participants, 'stakeholder communication' stands out as the most highlighted type of communication competence. Following stakeholder communication is intra-team communication, effective communication skills, persuasive communication, social communication, and empathetic communication. Furthermore, network-focused communication, marketing communication, professional language in communication, listening-persuasion in communication, and trustworthiness in communication emerge as sub-themes highlighted within the overarching theme of communication competence in the work environment.

Authors: Azzopardi Andrew , Farrugia Martina 
Published: October 2023

The objective of the paper is to conceptualise how social housing impacts the life of tenants and how it affects their social mobility.
Firstly, the paper looks at defining social housing to helps us get a better understanding of the subject matter. It highlights that social housing is a residential rental space provided at specific rates to be afforded by those who are considered vulnerable in society. It is a tool to improve the lives of those in vulnerable positions due to poverty, disability and mental issues to mention just a few. Children who live and grow up in stable social housing will have a better chance at accessing education, their wellbeing will be more positive, increased job prospects and a better outlook on opportunities.
Secondly, the paper addressed the impacts social housing has and its effects on social mobility for tenants. It discusses how income plays a vital role in obtaining social housing, how the wellbeing of tenants is essential in fostering a better self, how individuals who live in social housing can come together and form communities to deter crime, how living in safe social housing can impact positively effect on mental health, how it encourages tenants to find work and how it helps children strive for better and manage to break the cycle of poverty. However, notwithstanding the positive, social housing is not perfect and if not taken care of and is not funded properly then it could be a detriment to tenants’ social mobility.
Methodology
Desk research was carried out to identify an in-depth understanding of the topic. Apart from this, key experts from the Faculty for Social Wellbeing shared their expertise through various informal discussions.

Мета. Дослідження впливу антигістамінних активних фармацевтичних інгредієнтів (АФІ) лоратадину та дезлоратадину на активність 15-ліпоксигенази в реакції ферментативного окиснення лінолевої кислоти як субстрату.
Методика. Вивчення кінетичних закономірностей та механізмів інгібування 15-ліпоксигенази з використанням спектрофотометричного методу. Розрахунок кінетичних параметрів здійснювали згідно зі стандартними методиками та кінетичними моделями за допомогою програмного забезпечення SigmaPlоt 14.0.
Результати. Досліджено залежність стаціонарної швидкості перетворення субстрату 15-ліпоксигеназою від концентрацій субстрату без активатора та в присутності лоратадину в різних концентраціях. Встановлено, що лоратадин дозозалежно прискорює перетворення субстрату ензимом і, таким чином, проявляє потенційні прозапальні властивості (Ka=29,60±8,28 мкМ). Показано, що у присутності дезлоратадину в концентраціях 25 мкМ, 50 мкМ, 100 мкМ в системі окиснення лінолевої кислоти 15-LOX спостерігається зменшення стаціонарної швидкості перетворення субстрату ферментом. При цьому концентрація напівмаксимального інгібування ферменту складає IC50=287,91±29,02 мкМ. Встановлено механізм інгібування 15-ліпоксигенази дезлоратадином, який відповідає моделі Mixed (Partial), тобто змішаного (часткового) типу інгібування (R2=0,9688).
Наукова новизна. Вперше встановлено, що лоратадин на відміну від дезлоратадину активує 15-ліпоксигеназу, що свідчить про його потенційні прозапальні властивості.
Практична значимість. Проведені дослідження доводять, що дезлоратадин може потенційно застосовуватися у якості активного фармацевтичного інгредієнта лікарських засобів з протизапальними властивостями, тому що він є дозозалежним інгібітором 15-LOX. Таким чином, використовуючи даний АФІ можна уникнути явища поліпрагмазії та значно зменшити кількість побічних реакцій в організмі людини, які зазвичай спостерігаються при традиційній терапії нестероїдними протизапальними лікарськими засобами. Зроблено висновок, що в геріатричній практиці для лікування алергічних захворювань доцільно надати перевагу лікарським засобам на основі дезлоратадину. Тривалий прийом лоратадину у людей літнього віку може провокувати посилення запального процесу і пришвидшення оксидативного стресу.

Power can change how people act, how they think, what they do, and what policies they follow. People can reflect their power through the use of politeness strategies in their speech. This study aims to identify the types of politeness strategies and sub-strategies used in characters of Bridgerton Season 1 and explain how power is represented through politeness strategies. Its scenes and dialogue show qualities of decency and strength that need more exploration using the design of descriptive qualitative method. The pragmatic analysis in this study employed the theory of politeness strategy and the representation concept. The findings showed the use of bald on-record strategy, positive and negative politeness strategies, and off-record strategy. In addition, the representations of each strategy involved reflective, inflectional, and constructionist approaches. In the movie, the royal family, which includes kings, queens, princes, and their heirs, performed a symbol of power that plays a role in how power is used. Notably, the royal family serves as the show's symbol of power, highlighting its link to supremacy and authority. It implied that power is a sovereign thing based on authority and sovereignty. As the implication of this study, the future researchers should use sources of information that cover wider contexts.

The quality of air is very important for the environment and human life, however, along with developments in today's increasingly developed and modern era, the quality of the air itself is getting worse and the substances that become air pollutants, one of which is carbon monoxide. Exposure to high amounts of carbon monoxide gas over a continuous exposure period can of course increase carboxyhemoglobin levels in the blood, which will cause health problems. To determine the relationship between carboxyhemoglobin levels in the blood of motor vehicle mechanic workers in the Samarinda city area based on factors such as age, length of work, length of service, and smoking habits. This research used a cross sectional analytical survey design, and sample measurements used the Hindsberg-Lang method which was carried out in May 2023 with a sample size of 17 people and a Spearman rank statistical test was carried out to see whether there was a relationship between variables. 17 motor vehicle mechanics had COHb concentrations that exceeded the normal limit of 3.5%, where the lowest carboxyhemoglobin level was 6.10% and the highest was 9.64%. Correlation data obtained from the p value of age (p=0.000), length of service (p=0.000), time worked (p=0.000), and smoking habits (p=0.004) on COHb levels in the blood of motor vehicle mechanics. The Conclusion: COHb levels in motor vehicle mechanics are above 3.5% and there is a significant relationship between age, length of service, working time and smoking habits on COHb levels in the blood of motor vehicle mechanics.

Background: Population growth increases the demand for food all over the world. According to the Food and Agriculture Organization of the United Nations, by 2050 the world population will reach 9.1 billion people, for whom food production is expected to increase by 25-70 %. That will lead to an increase in the demand for alternative farming technologies allowing us to ensure higher yields in less time. One such alternative and highly profitable plant growing technology is soilless culture or hydroponics. Climate change, improved technological capabilities, and need to increase self-sufficiency are good reasons for the introduction of soybean in Armenia.Soy, as one of the richest and cheapest sources of protein, plays an important role in the diet of people in many countries. The seed of soybeans contains 17 % oil and about 50 % protein. Because soybeans contain no starch, they are a good source of protein for diabetics.Objective: To establish the possibility and efficiency of soybean cultivation in Ararat Valley by traditional agricultural method and by the regulated hydroponic system and to investigate the nutritional value of soybean seeds.Results: The cultivation method had some influence on soybean yield and on the biosynthesis of several nutritional components. Thus, soilless culture conditions contributed to the increase in soybean yield: the weight of seeds obtained from one plant was 38.7 g while in the soil it was only 19.9 g. Soil plants were distinguished by the maximum accumulation of fat (28.9 %), while hydroponic ones by the maximum content of protein (31.5 %) and sugar (6.3 %).Conclusion: The obtained results established the effectiveness of soybean cultivation in Armenia. The regulated hydroponic method ensures obtaining about 11.6 tons ha-1 of soybean seeds, 3.7 tons ha-1 of protein and 2.6 tons ha-1 of fat. The work was supported by the Science Committee of the Republic of Armenia, in the frames of the research project N 21T-4B167.Keywords: Glycine max (L.) Merr., soilless culture, proteins, fats, sugars
