Authors: Vaisman D. Sh. , Enina E. N. 
Published: August 2024

Aim. To assess the dynamics and structure of coronary artery disease (CAD) mortality rates in the Russian Federation (RF) and a number of regions.Material and methods. The study analyzed the dynamics of the mortality structure and the reliability of CAD mortality rates in the Russian Federation and a number of regions before and during the coronavirus disease 2019 (COVID-19) pandemic. For the analysis, statistical data of the Russian Ministry of Health and Rosstat C52 tables for 2019-2022 were used. The study used statistical and analytical methods. MSOffice Excel 2019 was used for data processing. The correct coding of death causes was determined by expert analysis.Results. In the Russian Federation and the regions studied in 2019-2022, there was no general trend due to territorial differences in the dynamics of CAD mortality rates and the proportion of acute and chronic CAD forms. An expert assessment in the studied Russian regions revealed errors in the preparation of medical certificate of cause of death. A decrease in the proportion of acute CAD types was noted in the Russian Federation as a whole, as well as in the Samara, Kaliningrad, and Tula regions, and an increase in the Belgorod and Tomsk regions. A decrease in the proportion of chronic CAD forms was noted in the Tula region, and an increase in the Russian Federation as a whole, Samara, Kaliningrad, Tomsk and Belgorod regions. An expert assessment in the studied regions revealed the following peculiarities in death certificates: the proportion of certificates with three completed lines of part 1 of paragraph 22 ranges from 11,1 to 30,3%.Conclusion. The high CAD mortality rate in the studied regions is associated mainly with errors in the selection of chronic CAD forms as the initial cause of death. Differences in mortality rates from CAD in a number of regions are associated with the incorrect selection, most often, of chronic forms as the initial cause of death before and after the COVID-19 pandemic.

Aim. To evaluate the potential of qualitative and semi-quantitative analysis of stress adenosine triphosphate perfusion cardiac magnetic resonance imaging (MRI) in patients with obstructive coronary artery disease (CAD) with stenosis ≥50%.Material and methods. Cardiac adenosine triphosphate perfusion stress MRI was performed in 49 patients with suspected or diagnosed CAD. The images were assessed qualitatively and semi-quantitatively. A zone of reduced signal intensity during the first passage of a contrast bolus with stress was taken as a stress-induced perfusion defect. Semiquantitative analysis was based on the construction of signal intensity curves of the contrast agent entering the left ventricular cavity and into the myocardium.Results. The detection of stress-induced perfusion defects according to cardiac stress MRI was significantly associated with coronary artery stenosis ≥50% (p<0,001) with sensitivity and specificity of 74,3 and 59,8%, respectively. The median myocardial perfusion reserve index (MPRI) was significantly lower in areas of coronary artery blood supply systems with stenosis ≥50% (1,25 [1,14-1,56]) than in areas with stenosis <50% (1,44 [1,21-1,70] (p=0,034). MPRI ≤1,33 in the areas of the coronary artery blood supply suggests coronary artery stenosis ≥50% (sensitivity, 64,52%, specificity, 63,95%; area under the curve =0,629±0,056; (0,519-0,738) (p=0,034)). An inverse relationship was established between the mean global MPRI and the number of stress-induced myocardial perfusion defects (r=-0,502, p<0,001).Conclusion. The developed technique of a semi-quantitative analysis with MPRI determination is effective in identifying obstructive CAD with stenosis ≥50% in addition to qualitative analysis.

Aim. To study the features of 24-hour ambulatory blood pressure (BP) monitoring (ABPM) in patients with hypertension (HTN) and comorbid pathologies within the hospital registry of a multidisciplinary medical center.Material and methods. The study was carried out within the GARANT hospital registry. This registry included 5781 patients. The HTN in the electronic patient record was revealed in 4725 (81,7%) patients (age 65,5±11,3 years, men 51,7%). Of these, ABPM was performed in 16,8% of patients (HTN+ABPM), 83,2% were in the comparison group (HTN without ABPM). The characteristics of patients in these groups were compared and ABPM feasibility was assessed.Results. In the HTN+ABPM group compared with the HTN without ABPM group, the mean age of patients was 63,9±13,9 vs 65,8±10,7 (p<0,01), women — 59,1 vs 46,1% (p<0,01), the mean number of cardiovascular diseases — 2,15±1,16 vs 2,68±1,16 (p<0,01), the mean number of non-cardiac diseases — 2,92±1,35 vs 2, 61±1,37 (p<0,01), office systolic and diastolic BP — 146,7±22,1/83,9±11,6 vs 136,9±19,7/79,2±10,4 mm Hg (p<0,01), respectively. The predominant blood pressure phenotype in the HTN+ABPM group is white coat hypertension (including during treatment) (49,2%). According to linear regression, the white coat effect is significantly positively associated with age, female sex, and negatively associated with prior myocardial infarction.Conclusion. The GARANT registry results revealed that in-hospital ABPM was more often performed on younger people, mainly women, with less severe cardiovascular multimorbidity. These patients were characterized by a higher level of office BP upon admission to hospital and a higher prevalence of HTN as the only cardiovascular disease. Carrying out ABPM in patients included in the registry seems justified.

Aim. To study the effect of extended-release (XR) metformin on humoral cardiometabolic markers and lipid peroxidation parameters in patients with heart failure with preserved ejection fraction (HFpEF), prediabetes and abdominal obesity (AO).Material and methods. The study included 64 people (men – 50%, median age – 58 [55,25; 59,75] years) with HFpEF, prediabetes and AO. All patients (groups A and B) received optimal therapy for HFpEF. In group A (n=32), metformin XR 1000-1500 mg/day was additionally prescribed. A general clinical examination was carried out, determining the level of soluble interleukin 33 receptor (sST2), N-terminal pro-brain natriuretic peptide (NT-proBNP), high-sensitivity C-reactive protein (hsCRP), the initial level of malondialdehyde (MDA) in low-density lipoproteins (LDL) and their resistance to oxidation with copper ions initially and after 6 months.Results. In group A, a decrease in NT-proBNP by 3,7% (p <0,001) was recorded. In group B, NT-proBNP values increased by 2,7% (p=0,013) compared to baseline levels. The decrease in NT-proBNP in the metformin group was accompanied by a decrease in hsCRP levels by 31% (p<0,001). No changes in sST2 concentration were demonstrated in either group. The level of MDA in LDL after 6-month metformin therapy became lower by 20% (p=0,002) relative to the initial value. When assessing the resistance to LDL oxidation with copper ions, the MDA content did not differ from the initial value. In group B, the initial MDA content in LDL increased by 3,7% (p=0,002) and after incubation with copper ions increased by 31,8% (p<0,001).Conclusion. In patients with prediabetes, HFpEF and AO, 6-month metformin XR + optimal HFpEF therapy was associated with a decrease in NT-proBNP, as well as the severity of oxidative stress in the form of a decrease in the concentration of MDA in LDL and the serum level of hsCRP.

Published: August 2024

Nursing students experience greater pressure from various sources of academic life, which ultimately creates stress among them. This study aimed to assess the impact of parental pressure and peer-related factors on academic performance of undergraduate nursing students, and to explore its relationship with their academic performance, and to determine the association of sociodemographic variables on parental pressure and peer-related factors. A descriptive, cross-sectional survey design, with a convenience sampling was adopted in this study. Participants were 408 undergraduate nursing students belonging to first, second, third or fourth year, and studying in various nursing colleges at Ernakulam district, Kerala, India. The data were collected using a socio-demographic questionnaire, parent pressure rating scale, peer- influence rating scale and an academic performance assessment rating scale. About 79.41 percent and 66.91 percent of the participants reported to have low parental pressure and peer influence on their academic performance respectively, and 20.5 percent and 32.59 percent of the participants reported moderate parent pressure and peer-influence on their academic performance respectively. A highly significant weak negative correlation was found between parental pressure and academic performance and between peer-related factors and academic performance. Parental pressure was significantly associated with birth order of the participants, father’s occupation and the study type of the participants. The study results suggest that there is a significant negative influence of both parental and peer-related factors on academic performance of adolescents. Future studies can explore in detail the factors which could positively and negatively influence the nursing students’ academic performance.

Published: August 2024

Background:Previous studies have recognized the potential of the Vertebral Bone Quality (VBQ) score for predicting fractures. However, these studies often have lacked longitudinal perspectives and have not focused on community populations. Our study aimed to enhance the predictive capacity of the VBQ score by investigating its correlation with new vertebral fractures (NVFs) that were detected 11 years later in a community-based cohort and by developing a comprehensive prediction model.Methods:This study was a population-based study conducted in the Minami-Aizu area in Fukushima Prefecture, Japan. One hundred and thirty participants voluntarily underwent T1-weighted magnetic resonance imaging (MRI) of the lumbar spine in 2004 and 2015. VBQ scores were ascertained from the 2004 scans. NVFs that occurred between 2004 and 2015 were detected based on a ≥20% reduction in vertebral height on the midsagittal sections of the MRI. Other predictors that were considered included age, sex, body mass index, smoking history, heart disease, cerebrovascular disease, respiratory disease, and existing vertebral fractures (EVFs). A logistic regression analysis was conducted.Results:The logistic regression analysis indicated that the VBQ score, age, sex, and EVFs were significant predictors of NVFs. The prediction model showed an area under the curve of 0.84, suggesting excellent discriminatory power. The calibration capacity was confirmed using the Hosmer-Lemeshow test.Conclusions:The VBQ score was significantly correlated with the long-term incidence of NVFs in a community population. The prediction model exhibited satisfactory discrimination and calibration capacities, highlighting the use of the VBQ score as a potential tool for long-term prediction of NVFs.Level of Evidence:PrognosticLevel II.

Comparative economic analysis of urban sanitation interventions in low- and middle-income countries: a systematic review
Authors: Ross Simon , Fane Simon , Foster Tim 
Published: August 2024

ABSTRACT

This review assesses evaluative criteria for least-cost economic analyses of citywide inclusive sanitation (CWIS) interventions, focusing on their alignment with the practical needs for decision support in low- and middle-income countries. We examined the literature from 2003 to 2022 that compares the costs and benefits of urban sanitation interventions to analyse their capacity to select cost-efficient and equitable urban sanitation options. The analysis revealed that finer disaggregation of cost perspectives could better articulate the diverse demands for services. Furthermore, options for comparison should be framed in addition to the diverse service provision models already existing within a context to ensure these perspectives are included. Developing the capacity to forecast a context-specific without-project scenario, using locally derived cost data as a basis of comparison, will be essential for adhering to CWIS planning principles. In addition, involving marginalised users more effectively in decision-making processes within economic analyses is essential for advancing equitable service provision. Future comparative economic analysis studies should embrace the complexities of CWIS contexts by supplementing broad-scale comparisons with detailed, context-sensitive evaluations to support more inclusive urban sanitation planning.

Published: August 2024

ABSTRACT

Residuals of refractory organics in water create a deep hazard to the water environment and human health, hence it is urgent to develop efficient approaches to remove refractory organics. Being a novel oxidizer, periodate (PI, IO4-) is considered to be stable and efficient in advanced oxidation processes for degrading refractory organics, such as antibiotics, dyes, pesticides, etc. Since the activity of PI alone is low, it is necessary to activate the PI to form active species in effectively removing organics. The studies of PI activation via monometallic, bimetallic, metal oxides, metal complexes, etc., have obtained more concerns owing to the high efficiency in decomposing organics. However, no reviews related to these studies have been published in recent years. This review summarized the properties and uses of PI, analyzed degradation properties and mechanisms of various metals and metal-based complexes in activating PI to remove refractory organics, and highlighted the limitations of these processes as well as the future research directions.

Authors: Elviana T. , Liliawati W. , Sriyati S. 
Published: August 2024

Gasing is a traditional game played by the Malay people of Riau, crafted from wood shaped like an inflated fruit, with a rope made from bark. This game is played by the Malay community in Riau to spend time with friends and to celebrate special occasions in the province. The research explored the methods of making and playing gasing by the Malay people of Riau and analyzed the physics concepts involved in the game. This qualitative study employed a literature review, observation, and interviews. The literature review examines Malay culture and gasing games. Observations were conducted in Siak Regency to directly observe the gasing games, including the tools and materials used, the game rules, and player interactions. Interviews with cultural experts provided insights into the cultural significance and traditional knowledge of the Malay community about the game. The findings reveal that gasing is made using merbau wood (Intsia bijuga) and bebaru bark (Thespesia populnea). In play gasing, the rope is wound around the body of the gasing, and the player takes a stance holding the gasing. The Gasing is then thrown to the ground with a sharp jerk of the rope, causing it to spin rapidly and for a long duration. Observations identified several physics concepts in the game, including balance, mass distribution, friction force, moment of inertia, rotational motion, angular momentum, kinetic energy, and surface area. The application of physics concepts in gasing highlights its potential as a valuable resource for ethnoscience-based physics learning.

Published: August 2024

The high concentration of nitrogen dioxide (NO2) directly results in Klang Valley’s air quality deterioration, causing a public health risk. This study was conducted to analyse the daily-averaged and annual concentration of nitrogen dioxide (NO2) on a spatial-temporal scale at five continuous monitoring stations under the Department of Environment (DOE) in Klang Valley, namely, Klang, Shah Alam, Petaling Jaya, Kajang, and Cheras from 2000 to 2009 using Man-Kendall statistical analysis and interpolation technique in Geographic Information System (GIS). The result clearly showed that the Petaling Jaya station was identified as the most polluted compared to other stations, with an average concentration of more than 0.050 ppm every year and reaching the maximum concentration of 0.069 ppm where the mean was 0.030 in 2001. Based on the p-value derived from the Mann-Kendall statistical analysis, the Klang, Petaling Jaya, Shah Alam, and Cheras stations recorded a significant trend with p-values < 0.05 at 0.0001 and 0.020, respectively. The annual concentration of NO2 in all the stations was in the range of 0.015 to 0.04 ppm from 2004 to 2009, compared to 0.005 to 0.01 ppm from 2000 to 2003. The highest annual-averaged NO2 concentration was reported at the Petaling Jaya station between 0.035 and 0.004 ppm for all years except 2007 and 2009 when concentrations were in the 0.03 to 0.035 ppm. Notably, the Petaling Jaya station had the highest annual NO2 concentration, which ranged from 0.025 to 0.04 ppm due to emissions from motor vehicles. The major pressure on road infrastructure was recognised, mainly a lack of space to accommodate the effect of the maximum density of motor vehicles and traffic, resulting in traffic congestion in the city centre.
Surgical tactics for distal tibial fractures. Literature review
Authors: Buryanov O.A. , Tsapenko H.S. , Omelchenko T.M. 
Published: August 2024

Background. Fractures of the distal tibial epimetaphysis (pilon fracture) account for 5–7 % of all tibial fractures and 10–15 % of all lower extremity bone fractures. The percentage of treatment failure in pilon fractures remains high and reaches 38–40 %. An important factor causing this is the lack of algorithms, accepted treatment protocols, and a system for predicting the effects of therapy. Purpose of the study: to analyze the features of modern surgical tactics in case of distal tibia fractures, to identify controversial and unresolved issues, to outline the possible reasons for a significant number of poor treatment outcomes, as well as to outline ways to improve them. Materials and methods. A review of 878 publications in the PubMed database over the past 15 years was conducted. 210 publications were selected and analyzed. The methods of analytical and descriptive statistics are applied. Results. Among the most debatable issues in the literature regarding which there is no consensus or a generally accepted approach that has evidence and justified tactics, the following should be highlighted: the choice of the time of surgical intervention; selection of method and means of fixation; rational tactics for osteosynthesis conversion; necessity and significance of fibula restoration during the treatment of pilon fractures; the importance of osteoplasty and the priority of restoring tibial anatomy according to the “column” principle; the place of primary arthrodesis in the surgical treatment for pilon fractures. Conclusions. These issues require further research with the development of new substantiated algorithmized treatment protocols based on a sufficient evidence base and a system for predicting the outcomes.

Published: August 2024

This research aims to examine the influence of public service quality and institutional image on student satisfaction, as well as its impact on student word of mouth at UIN North Sumatra. We used probability sampling techniques with proportional stratified random sampling, with 80 respondents. Data analysis was carried out using path analysis. The research results show that service quality has a positive effect on student satisfaction. Likewise, a strong institutional image also increases student satisfaction. In addition, an indirect influence was found between service quality and institutional image on student satisfaction through institutional image and service quality respectively. There is also a simultaneous influence between service quality and institutional image on student satisfaction. The better the quality of service and image of the institution, the higher student satisfaction. Student satisfaction has a positive impact on word of mouth. The implications of this research suggest improvements in service quality and institutional image to increase student satisfaction. This is important to increase marketing through word of mouth as an effective communication and marketing medium in facing increasingly fierce higher education competition.
