Authors: Akter Khaleda , Sultana Shamima , Begum Shelina
Published: December 2022

Background: Metabolic syndrome (MetS) is a major risk factor for cardiac mortality and morbidity. Hyperhomocysteinemia and folic acid are related with MetS. Both MetS and hyperhomocysteinemia adversely affect heart rate variability (HRV).
Objectives: To assess the relationship of vitamin B12, folic acid and homocysteine levels with HRV in female MetS patients.
Methods: This cross sectional study was carried out on 40 female MetS patients of 25-45 years of age. Forty apparently healthy female with similar age were control. Chemiluminescent immunoassay measured serum vitamin B12, folic acid, homocysteine level and time domain parameters of HRV were recorded by Powerlab 8/35, AD instruments, Australia. Independent sample ‘t’ test and pearson correlation coefficient test was used for statistical analysis
Results: In this study, all the time domain HRV variables ( Standard deviation of all RR intervals-SDRR, Coefficient variation of RR interval-CVRR, The square root of mean squared difference of RR intervals-RMSSD and Number of R-R interval differing >50ms from adjacent intervals divided by the total number of all R-R intervals-pRR50%) were significantly lower (p<0.05) in MetS patients compared to control. But correlation analysis showed only the folic acid level was significantly negatively correlated (p<0.05) with SDRR, CVRR, RMSSD and pRR50%.
Conclusion: The result of this study showed inverse relation of low HRV with low serum folic acid levels in female MetS patients.

Decriminalization of Drugs and the Support for Free Markets in the United States
Authors: Collins Christian , McCorkle William
Published: December 2022

For nearly 250 years, Americans have been able to ponder on their relatively short, but extensive ideological history. The United States was founded upon a number of ideals, but arguably the most predominant and preceding has been freedom. Heavily influenced by the Enlightenment, the U.S. founders laid the propositions protecting natural rights, while limiting governmental authority to retract upon these so-called “God-given rights.” The country’s roots lie in classical liberalism, and free markets have been an integral mechanism since 1776, through the championing of private property rights and economic freedom. However, since the War on Drugs, political discourse has distorted our historical vision and validated governmental coercion in criminalizing drug consumption and production whether that was for personal pleasure or legitimate medical reasons. The paper investigates this conflict of ideology and principle through the analysis of literature and survey data. The quantitative analysis revealed a negative relationship between support for free markets and drug decriminalization. The findings imply a substantial role of two-party politics in the U.S. in determining political beliefs outside of a clear ideology particularly related to issues like the War on Drugs.
Effectiveness of negative pressure wound therapy on chronic wound healing: A systematic review and meta-analysis
Authors: Burhan Asmat , Ali Khusein Nizam bin , Sebayang Septian Mixrova
Published: December 2022

Background: Negative Pressure Wound Therapy (NPWT) is considered an effective treatment in facilitating the healing of chronic wounds. However, its effect remains inconsistent, which allows for further investigation.
Objective: This study aimed to assess the effectiveness of the NPWT program in improving the management of chronic wound healing.
Design: Systematic review and meta-analysis was used.
Data Sources: The search strategy ranged from 2016 to 2021 in PubMed, CINAHL, ProQuest, and ScienceDirect.
Review Methods: Risk of bias was done based on the Risk of Bias 2.0 guideline using RevMan 5.4.1, and meta-analysis was done using Jeffreys’s Amazing Statistics Program (JASP) software version 0.16.3. Critical appraisal of the included articles was done according to Joanna Briggs Institute’s (JBI) appraisal checklist.
Results: A total of 15 articles were included, with 3,599 patients with chronic wounds. There was no publication bias in this study seen from the results of the Egger’s test value of 0.447 (p >0.05), symmetrical funnel plot, and fail-safe N of 137. However, heterogeneity among studies was present, with I2 value of 66.7%, Q = 41.663 (p <0.001); thus, Random Effect (RE) model was used. The RE model showed a significant positive effect of the NPWT on chronic wound healing, with z = 3.014, p = 0.003, 95% CI 0.085 to 0.400. The observed effects include decreased rate of surgical site infection, controlled inflammation, edema, and exudate, as well as increased tissue with varying forest plot size, as demonstrated by the small effect size (ES = 0.24, 95% CI -0.26 to 0.79, p <0.05).
Conclusion: The analysis results show that the standard low pressure of 80-125 mmHg could improve microcirculation and accelerate the healing process of chronic wounds. Therefore, applying the NPWT program could be an alternative to nursing interventions. However, it should be carried out by competent wound nurses who carry out procedure steps, implement general patient care, and give tips on overcoming device problems and evaluation.

Published: December 2022

Background: Maternal mortality reduction remains a world health priority. One of the causes of maternal death is bleeding after childbirth. However, little is known regarding barriers to reporting for postpartum hemorrhage care among postnatal women in Nigeria.
Objective: This research aimed to understand the perceived barriers to reporting postpartum hemorrhage care experienced by women and healthcare workers in Birnin Kebbi, North west-Nigeria.
Methods: Qualitative case research was employed in this study with face-to-face interviews among ten postnatal women who experienced bleeding and six healthcare workers. Data were collected from September to November 2021. The interviews were all audio-taped, transcribed verbatim, and analyzed using thematic analysis. NVivo Pro Version 12 was applied to organize further and manage the data.
Results: Six themes were developed: (1) knowledge deficit, (2) poor attitudes, behaviors, and performances, (3) low socioeconomic status, (4) lack of healthcare personnel, (5) cultural norms, and (6) lack of access to healthcare facilities.
Conclusion: The study findings might serve as input for healthcare policymakers and healthcare workers to improve health and reduce maternal mortality. Enhancing knowledge and awareness about reporting process is necessary to improve reporting for postpartum hemorrhage care among women. Training and continuous professional development of health care workers are also highly suggested to enhance the quality of care.

Published: December 2022

Background: Thrombectomy treatment is a critical procedure that emerged a few years ago, and nurses play a crucial role in the process, particularly in preventing complications and improving outcomes. Therefore, determining the quality of nursing care with best-fit quality indicators in patients with ischemic stroke receiving thrombectomy is necessary. However, no research has determined the nursing outcome quality indicators for these patients.
Objective: This research aimed to identify the nursing outcome quality indicators for patients with ischemic stroke receiving thrombectomy treatment.
Methods: Nineteen experts involved with patients with ischemic stroke receiving thrombectomy treatment were recruited. The Delphi method was implemented with three rounds between October 2021 to February 2022. Medians and interquartile ranges were analyzed.
Results: Twenty-eight nursing outcome quality indicators were developed and grouped into three components, including 1) pre-procedure (five indicators), 2) intra-procedure (six indicators), and 3) post-procedure (17 indicators).
Conclusion: This study revealed that the post-procedure of thrombectomy treatment had a greater number compared to pre and intra-procedures. The quality indicators developed in this research are practical and appropriate for nursing practice to enhance the quality of nursing care for patients with ischemic stroke receiving thrombectomy treatment.

Authors: Raji Fatimah , Morsi Nahed , Mahsoon Alaa , Sharif Loujain S.
Published: December 2022

Background: Owing to everyday educational activities, academic advisors often have to deal with mental health problems among students. Therefore, their mental health literacy must be assessed to determine whether they can detect mental health problems when working with the students.
Objective: This study aimed to assess health sciences academic advisors’ mental health literacy and their experiences dealing with university students facing mental health challenges.
Methods: A cross-sectional descriptive study was undertaken among a convenience sample of 133 health sciences academic advisors at the medical campus of a public university in Jeddah, Saudi Arabia. An electronic self-administered questionnaire using the Mental Health Literacy Scale (MHLS) was used to appraise participants’ recognition, knowledge, and attitudes toward ways to solve mental health difficulties. Data collection was completed from November 2020 to February 2021. Descriptive statistics, Student’s t-test for independent samples, One-Way Analysis of Variance (ANOVA), and Tukey’s test were selected for data analysis.
Results: Academic advisors were found to be highly literate about matters of mental health. The mean mental health literacy score was statistically significantly higher in those advisors who were lecturers, assistant professors, associate professors, and professors (p <0.001).  Additionally, the mean scores were significantly higher among advisors with a teaching role of lecturer rather than those who did not have the teaching role of a clinical supervisor (t = -2.331; p = 0.021).
Conclusions: The academic advisors had an elevated level of mental health literacy, and the highly experienced academic advisors could deal better with students having mental health problems. Hence, it is essential to continue to provide educational programs and training on mental health literacy to academic advisors, as it helps them identify the signs of mental health complications. Furthermore, it improves their skills and confidence when they offer student support in coping with mental health issues.

Authors: Ran Mingfei , Songwathana Praneed , Damkliang Jintana
Published: December 2022

Background: Helping first-time mothers who have just undergone cesarean section and transitioning from hospital to home with their infant is a complex process. Therefore, understanding what contributes to discharge readiness is necessary.
Objective: This study aimed to determine discharge readiness level and its associated factors among first-time mothers who have undergone cesarean section.
Methods: A descriptive cross-sectional study was conducted among 233 first-time mothers who had undergone cesarean sections selected using quota sampling from the two largest referral centers in China. Data were collected from March to June 2021 using a demographic characteristics form, Readiness for Hospital Discharge Scale-New Mother Form (RHDS-NMF), and Quality Discharge Teaching Scale-New Mother Form (QDTS-NMF). Descriptive and inferential statistics were used for data analysis.
Results: The discharge readiness of the respondents was at a moderate level. Age (r = -0.129, p = 0.049) and complications after cesarean section (r = -0.136, p = 0.038) had a negative correlation with discharge readiness. In contrast, the subscales of QDTS-NMF, particularly the content (r = 0.519, p = 0.000) and delivery (r = 0.643, p = 0.000), had a positive correlation with discharge readiness.
Conclusion: The findings enable nurses, midwives, and other healthcare professionals to understand discharge readiness and its related factors among first-time mothers undergoing cesarean section. It is also suggested that the quality of discharge teaching with a comprehensive assessment of first-time mothers preparing for discharge from the hospital and following the guideline to prevent post-cesarean section complications should be reinforced.

Stuckelberg Particle in a Coulomb Field: A Non-Relativistic Approximation
Authors: Ovsiyuk E. M. , Semenyuk O. A. , Ivashkevich A. V. , Neagu M.
Published: December 2022

We start with the Stuckelberg tensor system of equations for a boson with spin states S = 1 and S = 0 and fixed intrinsic parity, which is transformed to the matrix form, then generalize this matrix system to the generally covariant case with the use of the tetrad method. This equation is detailed in spherical coordinates in the presence of an external Coulomb field. After separation of the variables we derive the system of 11 radial equations. By diagonalizing the space reflection operator, this system is splitted into two system of four and seven equations for the states with the parities P = (−1) j+1 and P = (−1) j respectively. The system for the states with the parities P = (−1) j+1 leads to the known solution and energy spectrum. The system of seven equations for the states with the parities P = (−1) j is solved for the states with the total angular momentum j = 0 in terms of hypergeometric functions. The system of seven equations for the states with the total angular momenta j = 1, 2, 3, ... turns out to be very complicated, the only nonrelativistic approximation has been studied. The derived nonrelativistic equations are solved in terms of confluent hypergeometric functions, and the corresponding energy spectra are found. In addition, the general form of the nonrelativistic equations for the the Stuckelberg particle is derived in the presence of an arbitrary electromagnetic field.

О формировании расчетных схем некоторых дополнительных связей для упругих систем. Часть 1. Теоретические основы подхода
Authors: ЛЯХОВИЧ Леонид Семенович , АКИМОВ Павел Алексеевич
Published: December 2022

Для некоторых упругих систем с конечным числом степеней свободы масс, у которых направления движения масс параллельны и лежат в одной плоскости (например стержни), разработаны методы создания дополнительных связей, введение каждой из которых прицельно увеличивает значение только одной собственной частоты и не изменяет ни одну из форм собственных колебаний. Метод формирования матрицы дополнительных коэффициентов жесткости, характеризующих в этой задаче такую прицельную связь, может быть применен и при решении аналогичной задачи для таких же упругих систем, но у которых направления движения масс не лежат в одной плоскости (например пластины). Вместе с тем для таких систем сформулированы лишь требования к расчетным схемам дополнительных прицельных связей, а не методы их создания. Предложен подход и для таких систем. Рассмотрен вариант расчетной схемы связи, представленный стержневой системой с одной степенью активности. Выявлены некоторые особые свойства таких прицельных связей. Выполнена минимизация расхода материала на создание связи и учетны конструктивные ограничения. Особое внимание уделено модификации расчетной схемы связи, когда при ее формировании появляются стержни, "проходящие" сквозь исходную систему. Описаны теоретические основы предлагаемого подхода.
Анализ местных напряжений в стенке подкрановой балки
Authors: ТУСНИНА Ольга Александровна
Published: December 2022

Для подкрановых конструкций в цехах с кранами тяжелого и особо тяжелого режимов работы характерны повреждения и усталостные разрушения. Наиболее опасная зона, в которой возникают знакопеременные местные напряжения, - верхняя зона стенки подкрановой балки. На основе результатов численного расчета выполнен анализ местных напряжений, действующих в стенке подкрановой балки с фрикционным поясным соединением в двух сечениях: по верху стенки и под поясным уголком. Получено, что местные напряжения от сосредоточенного давления колеса распределяются неравномерно по толщине стенки балки с фрикционным поясным соединением, что связано с ее локальным изгибом. Однако это не учитывается в методике расчета, заложенной в отечественных нормативных документах. В связи с этим применение формул свода правил по стальным конструкциям для балок с фрикционным поясным соединением дает несколько заниженную величину местных напряжений в стенке в сечении под поясным уголком, которое является более нагруженным и опасным при проверке на усталость. Установлено, что эксплуатационный ресурс балки с фрикционным поясным соединением почти наполовину выше, чем у аналогичной сварной балки.
Giant cell arteritis in conditions of coronavirus infection (clinical case)
Authors: Babaeva A. R. , Lekareva I. V. , Kalinina E. V. , Zvonorenko M. S.
Published: December 2022

The complexity of timely diagnosis of giant cell arteritis (GCA), as the most common form of systemic vasculitis in the elderly, is due to the nonspecificity of clinical manifestations and the absence of specific immunological markers. New difficulties arise during the period of coronavirus infection, which manifests itself in similar syndromes and at the same time can provoke immuno-inflammatory rheumatic disease. In this regard, it is extremely important to make a correct differential diagnosis between persistent viral infection and the development of systemic vasculitis. This article presents a clinical observation demonstrating the complex process of diagnosis and differential diagnosis of GCA in the conditions of the COVID-19 pandemic. The patient was hospitalized due to a confirmed coronavirus infection. However, despite the standard therapy and the achieved eradication of the coronavirus, the symptoms characteristic of GCA and polymyalgia rheumatica (PR) persisted. A precision analysis of the clinical picture allowed us to establish that the typical manifestations of GCA and PR occurred in the period preceding COVID-19 infection. Subsequent in-depth examination made it possible to verify the diagnosis of GCA and PR based on the current classification criteria. The therapy with glucocorticoid and methotrexate made it possible to achieve remission. The presented observation will help to raise awareness of general practitioners and related specialties about the need to rule out GCA and PR in the case of prolonged unexplained fever, myalgia, headache, joint pain and swelling, transient visual disturbances, jaw claudication in elderly patients in the setting or after coronavirus infection.
Chronic viral hepatitis B and rheumatic diseases: Modern view on problem
Authors: Gridneva G. I. , Belov B. S. , Aronova E. S.
Published: December 2022

Infection caused by hepatitis B virus (HBV) is one of the most common hemocontact infections. The special life cycle of the hepatitis B virus, the course of infection, often hidden, and the high risk of developing life-threatening conditions, such as fulminant hepatitis and hepatocellular carcinoma, make it necessary to exercise special caution when choosing therapeutic tactics for rheumatological patients, since the vast majority of drugs used in rheumatological practice have immunosuppressive properties. This review updates information on the risks of reactivation of HBV infection in the treatment of currently used antirheumatic drugs, considers difficult to curate variants of chronic hepatitis B with delta agent and extrahepatic manifestations, in particular, thrombocytopenia. The most systematic and consistent approach to ranking the risk of reactivation of HBV infection (low [less than 1 %], moderate [1–10 %] and high [higher than 10 %]), in accordance with the serological status of the patient, as well as the type and duration of immunosuppressive treatment used, is proposed by the American Gastroenterological Association. The authors have attempted to unify the current literature data according to this classification.

Alfacalcidol has shown its efficacy and safety in the treatment of patients with osteoporosis (OP) during various clinical studies. The article presents data from a study conducted in real clinical practice in order to assess the relevance of alfacalcidol in the treatment of OP patients and the patients' adherence to treatment. A survey of doctors and patients with OP and low-energy fractures was conducted. Alfacalcidol was prescribed by doctors in 27 % of cases, while in 19 % – in combination with antiresorptive drugs. Among the interviewed patients with the average duration of OP 3 years, 25 % of the respondents took alfacalcidol. Adherence to treatment during the last year was 38 %. Follow-up of patients after a low-energy fracture showed that 31 % of them received alfacalcidol, among whom treatment adherence for 36 months was 50 % for monotherapy, and 21 % for combination therapy. Thus, the survey showed that in real clinical practice, alfacalcidol is widely used both in the management of patients with OP and after low-energy fractures.

Natural fodder lands are the main base for providing animal husbandry with the necessary voluminous fodder. On their area, different types of feed are produced, including for feeding during the stall period. The article presents the current state of long-term experience, which has been going on for 88 years without changing the scheme. The scheme of the experiment included different doses of lime and fertilizer and three modes of use (blocks). The composition of vegetation during regular mowing of green mass against the background without the use of fertilizer is represented by a cereal-legume-forbs type, and against the background of fertilizer application, it is a cereal-forbs type of formations. The protected regime (block without use) against the background of small doses of lime leads to overgrowing with shrubs and forests. Only the aftereffect of high doses of lime, which leads to a weak acidity of the soil, contributes to the preservation of meadow vegetation.

Full-fledged feeding of animals is the basis for the manifestation of their genetic potential of productivity and transformation of feed nutrients into products. This is possible only with the introduction of feeds into the diets that ensure their fullness with energy, protein, minerals, vitamins in the necessary quantities and ratios. In this regard, the narrow-leaved lupin is of great interest. In terms of protein content and amino acid composition, it is almost equivalent to soy. In addition, unlike soy, lupin grain does not contain trypsin inhibitors, which allows it to be used for ruminants without pretreatment and in sufficient quantities. As a result of exploratory research, compound feeds-concentrates containing extruded grain of lupine, fodder beans (50%), flax, paisa, as well as crushed cereals were developed and tested. New recipes of compound feeds with a high content of the energy-protein complex of crops grown in the Kaliningrad region ensure high productivity of animals. In the cows of the experimental groups for 60 days of the accounting period of cows, the average daily milk yield of natural milk was higher by 2.05 and 3.27 kg. Milk of basic (3.4%) fat content was obtained by 165 kg and 265 kg, milk fat by 5.63 kg and 9.04 kg and milk protein by 4.55 kg and 6.97 kg. At the same time, their cost is significantly less than soy, sunflower and rapeseed meal purchased outside the region. Taking into account the cost of feed, additionally received from the sold products, in comparison with the control, for the I experimental group 13483 rubles and II experimental 21255 rubles, from every 15 cows.
Monogenic causation of pediatric nephrolithiasis

Published: December 2022

Nephrolithiasis is a condition in which crystals precipitate out of the urine forming kidney stones in the renal calyces and pelvis. Approximately 80% of stones are composed of calcium oxalate and calcium phosphate. In recent years, there has been a significant increase in the prevalence of nephrolithiasis across populations, specifically in that of the pediatric population. The etiology of stone disease is multifactorial, and includes environmental, dietary, hormonal, and genetic factors. Evidence for monogenic causation (also known as Mendelian or single-gene disorders) in nephrolithiasis includes the finding that 30% of children with stone disease report a positive family history, with monogenic nephrolithiasis accounting for approximately 30% of cases. Monogenic nephrolithiasis can occur in isolation or may be the result of an underlying genetic disorder including autosomal dominant hypocalcemia (ADH), primary hyperoxalurias, and hereditary hypophosphatemic rickets with hypercalciuria (HHRH), to name a few. Currently, there are 41 known genes that represent monogenic causes of human nephrolithiasis. Since early detection of these mutations can in some cases prevent the progression to end stage kidney disease in pediatric patients, establishing the genetic basis for nephrolithiasis is increasingly important. Here we provide an overview of kidney stone disease in children with a focus on monogenic causation in the pediatric population.
A Modal-Decay-Based Shock-Capturing Approach for High-Order Flux Reconstruction Method
Authors: Ma Libin , Yan Chao , Yu Jian
Published: December 2022

The increasing demand for high-fidelity simulations of compressible turbulence on complex geometries poses a number of challenges for numerical schemes, and plenty of high-order methods have been developed. The high-order methods may encounter spurious oscillations or even blow up for strongly compressible flows, and a number of approaches have been developed, such as slope limiters and artificial viscosity models. In the family of artificial viscosity, which measures smoothness using the modal coefficients, the averaged modal decay (MDA) model employs all of the modes instead of only the highest mode as in the highest modal decay (MDH) model, which tends to underestimate the smoothness. However, the MDA approach requires high-order accuracy (usually P≥4) to deliver a reliable estimation of smoothness. In this work, an approach used to extend the MDA model to lower orders, such as P2 and P3, referred to as MDAEX, was proposed, where neighboring elements were incorporated to involve more information in the estimation process. A further controlling of the value of artificial viscosity was also introduced. The proposed model was applied to several typical benchmark cases and compared with other typical models. The results show that the MDAEX model recovers the expected accuracy better than the MDA model for P2 and P3 and captures flow structures well for shock-dominated flows.
Low-Energy Transfer Design of Heliocentric Formation Using Lunar Swingby on the Example of LISA

Published: December 2022

Space-based gravitational wave (GW) detection at low frequencies is of great scientific significance and has received extensive attention in recent years. This work designs and optimizes the low-energy transfer of the heliocentric formation of GW detectors, which starts from a geosynchronous transfer orbit and targets an Earth-like orbit. Based on the example of the Laser Interferometer Space Antenna (LISA), the transfer is first designed in two-body dynamical models and then refined in simplified high-fidelity dynamical models that only consider the major orbital perturbations evaluated here. The main contributions of this work are to present an adaptive model continuation technique and to exploit the lunar swingby technique to reduce the problem-solving difficulty and velocity increment of orbital transfer, respectively. The adaptive model continuation technique fully reveals the effect of perturbations and rapidly iterates the solutions to the simplified models. The simulation results show that the lunar swingby does reduce the energy needed to escape the Earth’s sphere of influence. It is found that the gravitation of the Earth–Moon system has a significant contribution to reducing the velocity increment. The solution of low-energy transfer in the simplified models is that the duration is 360.6615 days and the total velocity increment is 0.8468 km/s.
