Authors:   People & Global Business Association, Quazi Sagota Samina Quazi Sagota Samina
Published: June 2024

Purpose: The purpose of this study is to evaluate profit earning capacity of insurance companies in Bangladesh and to identify both company specific and macro-economic factors that influence the profitability.
Design/methodology/approach: This study uses panel data collected on 21 insurance companies operating in Bangladesh over the period of 2017-2021. Ordinary Least Square (OLS) method of regression analysis has been applied in the study to identify the determinant variables of profit of insurance companies.
Findings: The results show that volume of capital, proportion of investment and commission expense positively affect profitability of insurance companies whereas underwriting risk, tangibility, GDP and interest rate have neg-ative impact on profitability.
Research limitations/implications: In a small economy like Bangladesh, the existence of a large number of in-surance companies creates a question of sustainability of these organizations. To sustain in the long run, the in-surance companies need to earn sufficient profit. This study focuses on the factors that may influence and enhance profit earning capacity of these organizations. The limitation of this study is that the sample includes both life and non-life insurance companies. Therefore, future studies can be done focusing each sector separately.
Originality/value: There is no other study focusing on profitability of insurance companies in Bangladesh concen-trating recent scenario and large sample size. This research contributes the regulatory authority to direct insurance companies in the path of earning better profit. The findings of the study can also benefit the insurance companies as they can know the areas where they should focus more and take care of while operating business.

Transarticular fixation (TAF) of C1–C2 using the F. Magerl method and the Goеl–Harms technique (GHT) are the two most popular ways of forming spondylodesis at the atlantoaxial level. Nevertheless, comparative studies with a high level of evidence have not been published at present.

The aim of the study was to conduct a comparative meta‑analysis of the incidence of implant‑associated complications and fusion. The initial search in revealed more than 5,000 abstracts, after applying filters, 202 studies were selected, of which 16 works were included in this study. According to the results of the meta‑analysis, no significant differences were found between the methods of Goel–Harms and F. Magerl in the duration of surgery and intraoperative blood loss, as well as in the frequency of postoperative implant‑associated complications and spinal fusion of C1–C2 vertebrae.

Published: June 2024

Aim. To analyze the effectiveness of treatment and prevention of entrapped temporal horn (ETH) using various techniques.

Materials and methods. The study included 14 patients who underwent treatment or surgical prevention of ETH of the lateral ventricle after surgical resection of tumors in the projection of the trigone of the lateral ventricle. In 3 cases, microsurgical ventriculocisternostomy was performed; in 3 cases, shunting surgeries for ETH treatment; in 8 cases, ETH stenting.

Results. Tumor resection level, stenting effectiveness per presence/absence of hydrocephalus, and adequacy of the chosen ETH treatment and prevention methods were analyzed. In all 3 cases of ventriculocisternostomy, tumor resection was radical, stoma was strong, ETH opened, hydrocephalus was absent. In 3 patients with shunt implantation, radical resection was performed in 1 case; in 2 cases subtotal resection was achieved; shunt dysfunction due to tumor progression was observed in 1 patient during long‑term follow‑up. In 7 of 8 patients with cases of ventricular stent implantation for treatment/prevention of ETH, tumor resection was total; in 1 patient subtotal. Stenting performed in the postoperative period for treatment of hydrocephalus had positive clinical effect in 100 % of cases (non‑focal neurological symptoms, stasis in the fundus, speech disorders regressed). In stenting for hydrocephalus prevention, a positive effect was also observed (no increase in the size of the ventricular system, shunting surgeries in the postoperative period were not required). In the analyzed patient group (n = 14), de novo neurologic deficit did not develop, no cases of infectious complications and cerebrospinal fluid leak were observed, stent did not dysfunction.

Conclusion. Intraoperative ventriculocisternostomy is a reliable physiological technique for ETH prevention. Stenting of the ventricular system is an accessible and effective technique for ETH prevention. Single‑step stenting after tumor resection allows to avoid this complication in the long‑term and is not associated with surgical complications of distal stenting. The use of stenting surgeries has its advantages and disadvantages which makes this method acceptable but not universal. Implantation of shunt in the long‑term period is the method of choice for ETH treatment.

Aim. To evaluate the frequency and clinical characteristics of positional neuropathies in patients with cancer who underwent surgery.

Materials and methods. A retrospective study of medical records of patients undergoing surgical treatment in 2023, who showed signs of secondary neuropathy of the upper and/or lower extremities in the postoperative period. The main analyzed parameter was the frequency of postoperative neuropathies among patients who underwent surgery; additional parameters were the degree of neurological deficit according to the neurological deficit assessment scale, the median regression of neurological deficit.

Results. The study included 29 patients who underwent surgery at the National Medical Research Center of Oncology named after N. N. Blokhin in 2023, who developed a clinical picture of positional neuropathy in the postoperative period. The overall incidence of positional neuropathies was 0.28 %. Neuropathies of the brachial plexus were predominant (96 %). A severe degree of neurological deficit was noted in 35 %, medium – in 45 %, mild – in 20 % of patients. 27.5 % of patients continued to have varying degrees of neurological deficit over a 10-month period.

Conclusion. Positional neuropathies can persist for a long time; it is necessary to develop methods for their prevention.

Authors: Salimova A. A. , Makarova M. V. , Kurdanova M. Yu. , Kuvshinov Yu. P. , Karasev I. A. , Davydkina T. S.
Published: June 2024

Introduction. The standard of treatment of rectal cancer is a combined or complex technique in the form of neoadjuvant chemoradiotherapy (CRT) followed by surgery or observation, with proven radicalization of CRT. Currently, the most adequate methods of evaluating the results of CRT are endoscopic diagnostics. The most reliable visual criteria for endoscopic examination of absence or presence of residual tumor are: complete response (flat white scar, telangiectasia), partially complete response (uneven mucosa, small nodules on mucosa, superficial ulceration, slight persistent erythema of scar) and incomplete response (visible tumor).

Aim. The study is to assess sensitivity and specificity of endoscopic method in assessment of radicality of neoadjuvant CRT in patients with rectal cancer.

Materials and methods. A retrospective study of 75 patients with verified rectal cancer after CRT was carried out. Inclusion criteria: histologically verified rectal cancer (adenocarcinoma); endoscopic picture of clinical response of rectal cancer to CRT; absence of established distant metastases at the moment of examination. Exclusion criteria: morphological types of tumors other than adenocarcinoma of the colorectal type; patients with primary-multiple diseases.

Results. A retrospective study was conducted in 75 patients with a verified diagnosis of rectal cancer who underwent CRT at the first stage of treatment. All patients underwent endoscopic examination with evaluation of the degree of tumor regression, taking material for cytological and histological examination. In 57 (76,4 %) out of 75 patients on the basis of visual endoscopic picture the absence of residual tumor was stated, in 18 patients visual endoscopic signs were considered as presence of residual tumor. The results of morphological study in the first group of patients confirmed the absence of tumor in 51 cases (92.7 %). In the second group, in the presence of visual signs of residual tumor, morphological confirmation was obtained in 14 out of 18 patients (77.8 %). Morphological verification of residual tumor was obtained in 26.6 % of patients in the total group.

Conclusion. Endoscopic and histologic data can be decisive in the evaluation of the degree of radicality of neoadjuvant CRT.

Aim. To investigate the species composition and frequency of opportunistic pathogens in cancer patients diagnosed with non-small cell lung cancer (NSCLC) receiving chemotherapeutic treatment at the Federal State Budgetary Institution National Medical Research Center of Oncology named after N. N. Blokhin of the Russian Ministry of Health.

Materials and methods. A prospective open single-center study included a cohort of patients with locally advanced or metastatic NSCLC receiving drug antitumor therapy, aged 18 years and older. The study was observational in nature. The endpoint of this phase of the study was to determine the relative number of NSCLC patients with chronic infection (pneumocystis, herpes simplex virus (HSV) 1, HSV-2, cytomegalovirus (CMV), Epstein–Barr virus (EBV), human herpes virus type 6 (HHV-6) and their combinations).

Results. Antibodies to herpes viruses and/or pneumocystis were detected in patients (n = 18) diagnosed with NSCLC in 100 % of cases. Antibody titers corresponding to active infection were more characteristic for EBV and CMV, with CMV infection markers more often registered in titers corresponding to the acute stage of the disease, and EBV – in the reactivation stage without obvious clinical manifestations. In most cases, mixed infection with different pathogens was determined: combination of HSV-1 + EBV + CMV was found in 55.5 % (n = 10) of NSCLC patients; HSV-1 + EBV + CMV + HHV-6 – in 33.3 % (n = 6) of cases, HSV-1 + HSV-2 + EBV + CMV – in 5.5 % (n = 1), HSV-1 + HSV-2 + EBV + CMV + HHV-6 also in 5.5 % (n = 1) of patients. During bronchoalveolar lavage examination, pneumocystis were detected in 3 (42.8 %) out of 7 examined patients.

Conclusion. Based on the results of studies of a relatively small cohort of patients in the absence of clinical symptoms of infection in NSCLC patients, a high percentage of IgM and IgG antibodies, which are markers of opportunistic infections and their combinations, were detected. Pneumocystis was isolated from bronchoalveolar lavage in 42.8 % of cases. It is necessary to evaluate the results obtained in a larger number of patients to determine approaches to the prevention and treatment of opportunistic infections.

Introduction. Gastric cancer is a high burden on the healthcare system due to 1 million new cases every year. Most of these cases are diagnosed at a late stage.

Aim. The aim of this research is to perform epidemiological analysis about gastric signet ring cell carcinoma in the Tyumen region.

Materials and methods. Used data was taken from the regional cancer – registers of the medical center “Medical City”, Tyumen, Russia, which includes the data from 2012 to 2021. The histological tumor develops in accordance with the international histological classification of stomach tumors. The article examines such indicators as: morbidity, proportion of patients with stages I–IV, mortality, one-year mortality. Survival calculations were performed using TIBCO Statistica 13.5.0.17.

Results. 512 cases of gastric signet ring cell carcinoma were detected in the Tyumen region from 2012 to 2021: 51.9 % of them were men, 48.1 % were women. Morbidity over this period has slightly decreased. Average growth rate was – 2.05 %. Mortality increased in the same period. Average growth rate was 8.16 %. The average 1-year mortality over 10 years of the disease was 47.84 %, the average growth rate was negative (–1.19 %). Late diagnosis is still actual for this type of cancer 70.5 % of diagnoses were on the III or IV stages.

Conclusion. The performed epidemiological analysis of signet ring cell gastric cancer allows us to conclude that this problem is relevant for the Tyumen region. In the period from 2012 to 2021, the incidence of gastric signet ring cell cancer in the population has decreased slightly, but high mortality and one-year mortality remain due to detection at late stages. The average rate of increase in mortality is 8.16 %. Average one-year mortality rate from 2012 to 2021 was 47.84 %, and the average growth rate was – 1.19 %. The problem of early diagnosis also remains relevant; the proportion of patients whose diagnosis was made at stages III and IV was 70.5 %. This once again emphasizes the need for early and timely diagnosis. It is quite obvious that the effectiveness of the oncology service is closely related to how successfully the system of early detection of cancer patients is organized.

Published: June 2024

Measures to combat the COVID-19 pandemic have provided a unique dataset that can be analysed to test the influence of spectators on match results. Strict measures were introduced in the Czech Republic, where more than half of the 2020--2021 season was played completely without spectators. The matches of the Czech Extraliga from the last seven seasons (a total of 2604 matches were played between the seasons of 2016--2017 and 2022--2023) were used in the analysis of the influence of spectators on results. Previously developed models from association football were used to perform the analysis. The results of the analysis show that in matches without spectators, the influence of home advantage decreased significantly.

The Beck mine, located in the Republic of Karelia, Russia, is an abandoned mining site with significant potential for environmental contamination due to the presence of potential pollutants in its waste rocks. In this study, we investigated the chemical composition of mine waters and waste rocks and developed a theoretical model to understand waterrock interactions and the release of potential pollutants. Water samples collected from various locations on the Beck mine property were analyzed for chemical composition and showed low concentrations of total dissolved solids with pH values ranging from 6.42 to 7.74. The chemical composition of natural waters was determined by ICP-MS, ICP-AES, ion chromatography, potentiometric titration, and spectrophotometry. Equilibrium kinetic modeling was used to simulate water-rock interactions. The model predicted the concentrations of major and trace elements, demonstrating that dissolutionprecipitation and complexation are the primary mechanisms shaping the chemical composition of mine waters. The dynamics of dissolution-precipitation of Fe-containing minerals highlighted the importance of the duration of water-rock interaction, with stagnant mine waters exhibiting higher concentrations of heavy metals. In addition, the presence of dissolved organic matter played a critical role in the accumulation of iron and arsenic in the studied mine waters. Overall, this study highlights the utility of equilibrium kinetic modeling in understanding the behavior of heavy metals during water-rock interactions and provides valuable insights into the potential environmental impacts of abandoned mine sites such as the Beck mine.
Theoretical justification of the parameters of the rollers and the modes of flattening
Authors: Petrovets Vladimir R. , Kuzyur Vasily M. , Budko Sergey I.
Published: June 2024

BACKGROUND: The proposed design of the flattening device will ensure an increase in the quality of harvested grass feeds, since the time for drying it is reduced, and the additional adhesive agent increases the feed value, in addition, the loss of leaf and small-stemmed parts of plants is reduced by gluing them with stems in the total mass of the roll.
AIM: The set of technological measures used for the preparation of a particular feed from plants should ensure the maximal possible preservation of their nutritious, physiologically useful qualities. The aim of this study is to improve the quality of harvested grass feeds by increasing the feed value and reducing mechanical losses.
METHODS: As an object of research, a mower with devices for flattening and processing grass with an adhesive-nutrient agent, a centrifugal-type cutting mechanism, a flattening device with two ribbed rollers is considered. One of the conditions for the stable operation of the roller device is to ensure stems capturing by the rollers without unloading and clogging.
RESULTS: The principle of operation of the mower differs from the prototype in that the mown grass is flattened not by rolling between two rollers, which is effective with low grass yields and low device capacity, but by dragging the plants between adjacent surfaces of the protrusion of one roller and the groove of another roller, whereas the adhesive agent is applied by spraying onto the grass not before mowing but after flattening and forming a loose roll with a forming device.
CONCLUSION: The work was analyzed and the theoretical justification of the parameters of the rollers and their modes during the grass flattening was carried out. The parameters of the flattening device for forage harvesting must meet the following conditions: the capture of the mown grass and its rolling between the rollers with a constant compaction force.
Dynamics of the prevalence of diseases that complicated the course of childbirth and the postpartum period (based on the materials of the Samara region)

Published: June 2024

The prevalence of diseases that complicated childbirth and the postpartum period in the Samara region for the period 2009–2021 was investigated. The study was performed based on the official statistical reporting of the Samara region according to a standard scheme. The structure of pathological conditions was assessed. Then, the dynamics were analyzed, and modeling and medium-term forecasting were conducted. Structure analysis was carried out based on the 2016 data. Forecast was performed for the medium term (5 years). Notably, premature rupture of membranes (55.8%) is the most common complication of childbirth and in the postpartum period, followed by obstructed labor (11.4%), childbirth complicated by umbilical cord pathology (10%), childbirth complicated by hypertensive disorders such as preeclampsia and eclampsia (9.3%), and various labor disorders (9.1%). However, the considered conditions indicated in the official statistical reporting explain only 61.1% of all complications of childbirth and in the postpartum period, and 38.9% of all conditions remain unknown, which makes prevention, timely diagnosis, and effective treatment of these conditions challenging. The underreporting of cases of hypertensive disorders during pregnancy is evidenced by their higher frequency during childbirth. Only 25%–30% are complications during pregnancy of the number of complications of this pathology during childbirth and the postpartum period, and the downward trend in the prevalence of this complication during pregnancy is combined with an upward trend during childbirth and the postpartum period. The prevalence of all major extragenital complications during labor and the postpartum period showed a downward trend, except diabetes mellitus. The complexity of the analysis lies in the fact that the level of registration of the same pathological conditions during pregnancy and childbirth and in the postpartum period is extremely different. The data obtained indicate the need for improving the early diagnosis of gestosis and statistical recording of complications of pregnancy and childbirth and provide basis for improving the system of monitoring pregnant women and correct diagnosis of pathology in early pregnancy.

Published: June 2024

Based on the annual statistical reports for 2018–2023 and the cumulative median prevalence of various studies in 2009–2020 in Russia, the prevalence of peptic ulcer with uncomplicated and complicated course and various forms of gastritis in servicemen of the Regardie of the North Caucasian District was estimated, and the current trends are explained. The incidence of peptic ulcer with uncomplicated and complicated course and various forms of gastritis among the servicemen of the Regardie of the North Caucasian District for the specified period ranged from 11.521% to 16.351% (confidence interval: 10.515–12.588 and 15.233–17.517, respectively) and from 27.212% to 51.889% (confidence interval: 25.791–28.669 and 50.316–53.460, respectively). Random effects analysis has demonstrated different true effect sizes relative to the overall average. The revealed statistical patterns are only the first stage in an ongoing study on the prevalence of upper gastrointestinal diseases among the servicemen of the Regardie of the North Caucasian District. In general, the prevalence of peptic ulcer disease, including with a complicated course, and various forms of gastritis among military personnel was 13.270% and 37.679%, respectively (confidence interval: 10.617–16.170 and 24.292–52.102, respectively), showing an upward trend. The expected prevalence of peptic ulcer and gastritis in 2023 was 16,351 and 51,889%, respectively, which is not accidental and depends on the impact of specific risk factors. The identification of risk factors enables the development of measures to prevent delayed complications of the pathology under study and improvement of health in servicemen of the Regardie of the North Caucasian District. Thus, the study of the health status of the general population and military personnel, in particular, and the effect of various environmental factors determines their social significance both in military medicine and the structure of the healthcare system.

Published: June 2024

The Texas Seismological Network (TexNet) has enabled real-time monitoring of induced earthquakes since 2017. Before 2017, location uncertainties and temporal gaps in seismic data obscure correlations across Texas between seismicity and saltwater disposal or hydraulic fracturing. Depth biases also complicate linking anthropogenic stress changes to faults. We relocate 73 M 1.5+ earthquakes from the TXAR catalog (2009–2016) relative to the centroid of a calibrated core cluster consisting of 116 earthquakes from the TexNet catalog post-2020, in the southern Delaware basin south of the Grisham fault zone. Hypocentroidal decomposition relocation reduces spatial uncertainties of the TXAR events to <5 km and provides updated depths. The core cluster has uncertainties less than <300 m and depth constrained from near-source stations and S−P differential times. The majority of relocated TXAR events indicate the triggering of northwest-trending faults at a mean depth of 1 km below sea level, suggesting a causal connection with shallow saltwater disposal and consistency with post-2017 seismicity. Spatiotemporal patterns of pre-2017 seismicity and saltwater disposal highlight initial triggering via pore-pressure stress perturbations from nearby low-volume injections and later from southeastward pressure diffusion along permeable anisotropic conduits and fracture zones. The comparison between pre- and post-2017 seismicity indicates shallow fault reactivation through similar triggering mechanisms since 2009.

Published: June 2024

This culminating project focuses on developing a culturally informed, community-based music therapy approach for older adults among ethnic Chinese immigrants. This population has faced discrimination and oppression, particularly in the historical context of both the United States and ethnic Chinese communities during and after World War II. The author examined the historical and cultural experiences of Chinese immigrants from their home countries and the United States, integrating these experiences with the unique characteristics and identity of this population. The project was further developed into a culturally informed, community-based music therapy approach by identifying and sharing culturally specific themes within eight music therapy group sessions conducted by the author. Given that the author shares this bicultural identity with group members, she assessed how these themes emerged in sessions, influenced by both participants and the author herself. The insights provided highlight the influence of cultural norms, beliefs, and unique musical experiences within this community, This approach reframes Western-based music therapy knowledge and practices into an integrated method tailored to this population.
Music in Inpatient Mental Health

Published: June 2024

Compassion fatigue is a form of burnout that affects healthcare practitioners. For music therapists and other workers in an inpatient psychiatric facility, compassion fatigue may arise due to the stress of working with patients who have experienced severe trauma, or because of systemic issues such as staff shortages and low salaries. Whatever the cause, compassion fatigue affects not only practitioners, but their patients as well, as it can impact the quality of care they receive. Self-care has often been cited as a remedy for compassion fatigue. This writer explored how music can be used as part of a self-care routine for practitioners in an inpatient setting. The information is viewed through the lens of Urie Bronfenbrenner's ecological systems theory, and the implications of the power dynamics that exist within an inpatient facility are studied. A literature review was conducted to explore existing methods of using music to combat compassion fatigue. Additionally, three board-certified music therapists with experience working in inpatient psychiatric facilities were interviewed. They discuss their experiences witnessing compassion fatigue, either in themselves or others, and generate ideas for music as self-care. Suggestions for further research and recommendations for future practice are explored.

Authors: Hwang Sungjun , Chun Seok-Joo , Chie Eui Kyu , Lee Jeong Min
Published: June 2024

Backgrounds/Aims: This study explored the initial institutional experience of using gold fiducial markers for stereotactic body radiotherapy (SBRT) in treating malignant hepatic tumors using real-time ultrasound-computed tomography (CT)/magnetic resonance (MR) imaging fusion-guided percutaneous placement.Methods: From May 2021 to August 2023, 19 patients with 25 liver tumors that were invisible on pre-contrast CT received fiducial markers following these guidelines. Postprocedural scans were used to confirm their placement. We assessed technical and clinical success rates and monitored complications. The implantation of fiducial markers facilitating adequate treatment prior to SBRT, which was achieved in 96% of the cases (24 of 25 tumors), was considered technical success. Clinical success was the successful completion of SBRT without evidence of marker displacement and was achieved in 88% of cases (22 of 25 tumors). Complications included one major subcapsular hematoma and marker migration into the right atrium in two cases, which prevented SBRT.Results: Among the treated tumors, 20 of 24 (83.3%) showed a complete response, three of 24 (12.5%) remained stable, and one of 24 (4.2%) progressed during an average 11.7-month follow-up (range, 2-32 months).Conclusions: This study confirms that percutaneous gold fiducial marker placement using real-time CT/MR guidance is effective and safe for SBRT in hepatic tumors, but warns of marker migration risks, especially near the hepatic veins and in subcapsular locations. Using fewer markers than traditionally recommended-typically two per patient, the outcomes were still satisfactory, particularly given the increased risk of migration when markers were placed near major hepatic veins.

Authors:   Saratov State University, Goremyko Maksim S.
Published: June 2024

Artificial intelligence is an important part of modern life. AI exists to improve lives and free up time and resources for the tasks that require thoughtful human action. The advent of artificial intelligence (AI) created new data analyzing the capabilities of the modern phenomenon of social networking, accurately analyzing and understanding the dynamics of online communities and users` sentiments. AI succeeds in such area as social media. Internet users use social media to communicate, search for information, buy things and even work. Social networks also have a high amount of data that can be used to analyze social processes and people's behavior. However, the amount of data is so large that so its processing and analysis can be a time-consuming process. Artificial intelligence can help to solve this problem. The article is devoted to the study of the role of artificial intelligence in the analysis of social networks, highlights the possibilities of AI and problems, considers various methods of analysis and data collection, such as social listening, natural language processing, as well as an automatic content classification system. The use of a heuristic approach to this issue based on AI helps to significantly speed up the process of data processing and reduce the cost of analysis that would be performed by manual labor. As a result, it was established that artificial intelligence has a great heuristic potential in the analysis of social networks. Its ability to analyze large amount of data, recognize patterns and identify data trends and also automate management tasks makes it a valuable tool for understanding social media trends and users` behavior.

The People’s Republic of China’s “One Belt – One Road” initiative has been rather fully analyzed in the research literature. However, until now, the full chronology of this Initiative has not been presented in Russian historiography. In the article, the authors analyze transformation of the “One Belt – One Road” Concept using a chronological approach. The article also uses a systematic approach, analysis of the current situation, and the method of situational analysis. The development of the Initiative, the regulatory framework, as well as the regular international Belt and Road forums held by China are examined. In addition, the article pays special attention to Russian-Chinese relations, since they become part of the implementation of the project. Special attention is paid to the challenges and promising areas of the Initiative. The authors come to the conclusion that the Concept can be considered as a global geopolitical project; it has sufficient potential for development in the Eurasian region, and can also become a part of a multipolar world order.

The article deals with the formation of the foundations of the social state in Russia at the turn of the XIX–XX centuries. At the same time, the emphasis is placed on the fact that representatives of political elite, differing in various ideological views and ideas about the ideal form of government, could agree on the need to expand social functions of the state. The aim of the article is to determine the influence of ideas about the need to build a social state in Russia and certain elements of this idea implemented in life on reducing contradictions in the ranks of the ruling elite. The most significant sources are the documentation of political parties in Russia, which were formed at the beginning of the XX century and took part in the work of the State Duma. These sources allow us to see that, despite sometimes significant differences in issues concerning the form of government, the state structure and political freedoms, most parties were inclined to recognize the need for the development of a social state in Russia. This was manifested in the introduction of relevant items in the party programs devoted to the working issue, development of the state insurance system, as well as the introduction of free education. The results of the study show that in Russia, as in most European countries, there was a gradual understanding of the need to build a social state. At the same time, consensus on this issue could help reduce the level of contradictions in the ruling elite. However, some discrepancies in specific programs of political parties regarding the elements of the welfare state could act as reasons for conflicts.

Background & Objectives: Carbon nanotubes (CNTs) serve as molecular carriers for in vivo and in vitro delivery. Initial studies have suggested that nanotubes in drug delivery can enhance the therapeutic response to anti-cancer drugs. The present study intended to investigate the effect of CNTs carrying tamoxifen (TAM-CNTs) on the induction of apoptosis in the MDAMB-231 cell line.
Materials & Methods: The cells were treated with various concentrations of TAM and TAMCNTs. The IC50 for these compounds was determined using a MTT assay. The cells were then treated with a lower concentration of IC50. The BAX and BCL-2 genes expression were evaluated by Real-Time PCR and Western blot. Flow cytometry was employed for evaluating apoptosis induction by TAM and TAM-CNTs.
Results: The IC50 value of TAM and TAM-CNTs in a 48-hour period was 66.19 mg/mL and 36.59 mg/mL, respectively. The results demonstrated that BAX in the cells treated with TAM and TAM-CNTs was upregulated 3.64 and 7.88 times, respectively (P <0.05). Conversely, BCL-2 was downregulated 3.98 and 5.31 times (P <0.05). Furthermore, Western blot experiments confirmed the expression of BAX and BCL-2 proteins based on their gene expression. Flow cytometry results indicated that the viability of MDA-MB-231 cells in the control group, TAM-treated, and TAM-CNTs-treated cells was 95.3%, 64.9%, and 13.75%, respectively. This suggests that TAM-CNTs significantly diminishes cell viability compared to TAM (P <0.001).
Conclusion: The findings revealed that TAM accompanied by CNTs exhibits a greater cytotoxic and apoptotic effect on MDA-MB-231 cells.

Published: June 2024

Background & Objectives: Cardiovascular disease is a leading cause of death worldwide. ECG signals are used to diagnose it. This study aims to eliminate signal noise by converting available wavelets and extracting existing waves. The location-related properties and amplitude of these waves will be extracted to develop a model based on the random forest algorithm for training and evaluating the algorithm.
Materials & Methods: This study uses the MIT-BIH dataset, which contains digital ECG signals extracted from Holter bands for different patients at Arrhythmia Hospital from 1975 to 1979. The study applies signal processing and machine learning techniques to classify ECG signals and identify heart patients. The MATLAB software implemented the algorithm, which was evaluated based on accuracy, error rate, TP, FP, Precision, Recall, F-Measure, and ROC criteria. These criteria were determined by a confusion matrix.
Results: The study results and comparisons demonstrate that the proposed method is highly effective in detecting heart patients. The proposed method’s accuracy was found to be 99%, which is higher than other machine learning methods.
Conclusion: The proposed method achieved an accuracy of 99.1957%, surpassing other machine learning methods like support vector machine, neural network, and Bayes.

Background & Objectives: Breast cancer is the most lethal malignancy in women. miRNAs function as epigenetic regulators and contribute to the pathogenesis of breast cancer. Nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1) and 3 (NFATc3), are targeted by microRNA-93 (miR93). This study aims to evaluate the expression of these genes in peripheral blood mononuclear cells (PBMCs) of healthy women and women with breast cancer
Materials & Methods: In this cross-sectional study, blood samples were collected from 20 healthy women and 20 women with early-stage breast cancer. After isolating peripheral blood mononuclear cells (PBMCs), RNA extraction and cDNA synthesis were performed. The expression of the desired genes was then examined by Real-Time Polymerase Chain Reaction (RT-PCR). Statistical analysis was conducted. A p-value less than 0.05 was considered statistically significant, and Student’s t-test was used to evaluate the relative changes in gene expression.
Results: The results demonstrated that the expression of NFATc1 and NFATc3 genes in peripheral blood mononuclear cells (PBMCs) of breast cancer patients was significantly reduced compared to their expression in healthy individuals. Conversely, the expression of the miR-93-3p gene was significantly lower in healthy women than in breast cancer patients (p < 0.05).
Conclusions: This study investigated the expression of miR-93-3p and its downstream targets, the NFATc1 and NFATc3 genes, for the first time in peripheral blood mononuclear cells. The expression levels were shown to be significantly different in patients with breast cancer compared to healthy women.

Authors: Mousavi Mahmood , Karimiankakolaki Zohreh
Published: June 2024

Background: This study aims to consider the effect of an educational intervention on the error rate of insurance documents in the deducting of hospitalization records of COVID-19 patients' health insurance among hospital staff.
Methods: The target population of this semi-experimental study was all personnel involved in the management of patients with Covid-19. Among the hospitals of the COVID-19 site in Chaharmahal and Bakhtiari provinces, one hospital was selected as the educational target group (24 individuals) and one hospital was considered as the control group (16 individuals) by lottery. To measure the effectiveness of education, the sample size of all cases of 19 patients with health insurance in two hospitals during two periods of October and March 2016 was determined. Data collection was performed by checklists and direct reviews of files, the health insurance system, and the hospital HIS system. Data analysis was performed using SPSS21 software.
Results: The number of deductions in the case of "Covid 19 hospitalized patients" of the health insurance decreased significantly in the intervention hospital from 1833 to 933 (p < .005) and increased in the control hospital from 447 to 2712 (p < .005). In the intervention hospital, the highest decrease in deductions in the hoteling service was from 235 (12.8%) to 2 (0.2%) cases (p < .001), and for medicines from 335 (18.2%) to 56 (6%) cases (p < .001).
Conclusion: The results demonstrated that staff training on the error in COVID-19 insurance documents during the coronavirus pandemic outbreak has reduced the number of insurance deductions in COVID-19 patients' records.
