DOCUMENTING MATERNAL AND CHILDCARE INFORMATION OF MOTHERS PRESENTED TO SUBSTANCE USE TREATMENT SERVICES: A QUALITATIVE STUDY OF REPORTS IN A CLINICAL CASE REGISTER
Authors: Canfield Martha , Brown Ashley , Nelson Ashley , Downs Johnny , gilchrist gail , Norton Sam
Published: June 2022

Background: Mothers comprise a significant proportion of women in substance use treatment services. These women have needs that, if not addressed, can negatively impact their capacity to parent. This study explores the feasibility of using free-text notes from electronic health records (EHRs) to identify factors which impair mothers’ ability to care for their children. Method: Qualitative analysis of EHRs of 50 women attending substance use services in Southeast London who were parents of dependent children (defined as mothers of children aged <18 years independent of living together). A sampling stratification process was developed to ensure an adequate volume of data were available and analysed per case. Search terms were identified and tested. Data from clinical notes and letters of communication with other services/agencies (free-text notes) were extracted using the identified search terms and deductive thematic analysis was conducted.Results: The mean number of documents per case was 92.17(SD = 18.51). Five themes with subthemes were identified: childcare arrangements, family context, safeguarding issues, factors that might impact the treatment plan and care of the child, and communication between the healthcare and child welfare systems. Conclusion: The study demonstrates a novel approach for exploring parenting-related characteristics of mothers in substance use treatment. Despite a range of maternal and childcare related information available on EHRs, the type of treatment and support being offered to patients in response to the reported information is less well documented. Findings highlight the need for further investments in implementing effective family-centred strategies within substance use services.

Published: June 2022

Differential HPA axis function has been proposed to underlie sex-differences in mental disorders; however, the impact of fluctuating sex hormones across the menstrual cycle on HPA axis activity is still unclear. This meta-analysis investigated basal cortisol concentrations as a marker for HPA axis activity across the menstrual cycle. Through a systematic literature search of five databases, 121 longitudinal studies were included, summarizing data of 2641 healthy, cycling participants between the ages of 18 and 45. The meta-analysis showed higher cortisol concentrations in the follicular vs. luteal phase (dSMC = 0.12, p = .004, [0.04 – 0.20]). Comparisons between more precise cycle phases were mostly insignificant, aside from higher concentrations in the menstrual vs. premenstrual phase (dSMC = 0.17, [0.02 – 0.33], p = .03). In all included studies, nine samples used established cortisol parameters to indicate HPA axis function, specifically diurnal profiles (k = 4) and the cortisol awakening response (CAR) (k = 5). Therefore, the meta-analysis highlights the need for more rigorous investigation of HPA axis activity and menstrual cycle phase.

Authors: Thalia Nita
Published: June 2022

The main goal of this study was to identify Key Performance Indicators (KPI) through e-learning Critical Success Factors (CSF) for an online course of English for Football in Iran. To this end, the researchers prioritized the e-learning CSFs proposed in the literature from an emic perspective exclusively for the online course of English for Football as a case study. The expert participants in this study were certified football coaching instructors from Iran Football Federation who took an open-ended questionnaire and wrote their statements of success for each CSF and rated them on Analytical Hierarchy Process (AHP) ratio scale through pairwise comparisons. Based on the collected statements of success, the researchers identified KPIs for an e-learning course of English for football. This study resulted in 24 KPIs in line with the CSFs in the literature and the statements of success proposed by the participants of this study. The results of AHP on the CSFs showed that respectively: course, instructor’s characteristics, learner’s characteristics, learning environment, instructional design, support, level of collaboration, knowledge management and technology knowledge were the important CSFs. Finally, the researchers arrived at KPIs based on each ranked CSFs and statements of success. This study could have implications for the ESP curriculum developers and online course organizers to strengthen their course structure by identifying, prioritizing and setting down CSFs and KPIs.

Jaffrey Beall defined predatory journals and created Beall’s list of predatory journals. Predatory journals exploit the open-access model - they are dishonest and lack transparency. Predatory journals fully developed in the years 2013 and 2014. Developing countries like South Asian and African countries with emerging research fields have the majority of authors published in predatory journals. Predatory journals are even found in reputed databases like PubMed, Medline, Scopus, Science Citation Index Expanded (SCIE) database, Emerging Sources Citation Index (ESCI), and EMBASE (Excerpta Medica dataBASE). There are numerous fake profiles in Facebook, LinkedIn, Twitter, WhatsApp, and Google; although they have been timely deleting such fake profiles. Journals must use institutional email addresses to maintain professionalism and quality. Focusing on quantity over quality of research papers, and lack of proper knowledge about predatory journals make new researchers victimized by such journals. This paper aims to provide proper knowledge about predatory journals and deliver useful tips to prevent genuine researchers from getting victimized by such journals. This paper also intends to provide thorough knowledge about fake social media accounts and email addresses used by such journals, and the importance of institutional email addresses.

Background: Blood transfusion is a liquid transplant. Nurses are having more responsibility in many aspects of the transfusion process such as taking and labeling blood samples, collection of blood from the blood bank, short term storage in ward areas, checking, administering, documenting transfusion process and monitoring of the patient, it is vital that they are through and methodical in all task related to transfusion to ensure patients safety and must be aware of the steps necessary at each stage to safe guard the patient. Nurses are responsible not only for the actual administration of the blood product and monitoring of the patient during its administration but they also need to efficiently identify and manage any potential transfusion reactions. It is important to remember that transfusion reactions can occur during the actual blood transfusion as well as for days and weeks following the administration of the blood product. Although blood transfusion reactions are rare, it is important that any nurse who administers a blood product be aware of potential reactions and knows how to manage these reactions safely and effectively.

Methods: This is a descriptive study to assess the knowledge and practice regarding blood transfusion and its complications.

Results: Forty-four percent (44%) of the nurses had obtained Proficiency Certificate Level (PCL) Nursing and Health Assistant (HA) degree qualification. Forty percent (40%) of the nurses had one year of experience. Forty percent of the nurses worked in general ward at the hospital. Almost 80% of the nurses (79%) of the nurses stated that they attended Continuing Nursing Education regarding blood transfusion. 59% of total respondents have adequate knowledge.

Conclusions: Continuous Nursing Education for the improvement of nurses’ knowledge and skills as well as routine monitoring should be carried out to ensure safe practice in blood transfusion.

Published: June 2022

Background and Aims:Transcatheter closure of the secundum atrial septal defect (ASD) has become an accepted alternative to surgical repair. We aimed to analyze and compare the changes in cardiac hemodynamics with transthoracic echocardiography (TTE) before, within 48 hours, and after 3 months of ASD closure.

Methods: This was a prospective, single-centered study of 43 patients who underwent ASD device closure in the Manmohan Cardiothoracic Vascular and Transplant Center during June 2020 to June 2021 with Amplatzer Septal Occluder under transesophageal and fluoroscopic guidance. The patients were evaluated with TTE before, at 48 hours, and 3 months after the procedure.

Results: At 48 hours and 3 months of device closure, the right atrial major dimension, the maximum blood flow velocity at the pulmonary valve orifice, mean flow velocity, velocity time integral, and E peak and A peak blood flow velocity at the tricuspid valve orifice were significantly reduced (P < 0.001). At 3 months, the dimensions and ejection fraction of the left ventricle showed significant increment (P < 0.001).   Likewise, the right atrial minor dimension and area, right ventricular basal, mid, and longitudinal dimensions, tricuspid annular plane systolic excursion, right ventricular Tei Index, and fractional area change were significantly reduced (P < 0.001). The main pulmonary artery diameter, pulmonary artery systolic and mean pressure, and the pulmonary vascular resistance and index were significantly reduced (p <0.001). The procedural success rate was 97.6%.

Conclusion: Echocardiographic evaluation demonstrated that cardiac hemodynamics and loading conditions improved significantly at 3 months after percutaneous closure of ASD. The transcatheter closure of ASD was safe with good short-term outcomes.
STUDY OF THIRD ORDER SYSTEMS SYNTHESISED USING THE ALGORITHM FOR PROVIDING APERIODIC SLIDING MODE
Authors: Derets O. , Derets O. , Sadovoi O.
Published: June 2022

The relevance of the work is dictated by the continuous growth of requirements for the dynamic characteristics of electric drives. A typical task of designing positional electric drives is the indispensable provision of the aperiodic nature of the movement of the executive body, which is carried out with a boundary speed for given restrictions. This requires the formation of transient diagrams by means of monotonic functions of time.

Creation of a single tool for the synthesis of systems with the desired form of timing diagrams based on the N–i switching method in the form of a generalized numerical algorithm allows you to determine the setting of the controllers for the entire range of displacements. It is obliged to ensure the aperiodic nature of transitional actions in third-order control systems. The aim of the study is to experimentally test the effectiveness of the developed technique for aperiodization of dynamic regimes.

Synthesis of the parameters for the sliding control system with a cascade structure, which has non-oscillatory entry into the sliding mode was performed for different positioning modes. This problem was solved by integrating the results of the previous works of the authors concerning the synthesis in the analytical form of settings for third-order systems for working out individual forms of trajectories. As a result, a complex tool for structural-algorithmic synthesis was created, which ensures the consistent application of partial solutions. The novelty of this work lies in obtaining the transient characteristics of typical dynamic modes as a result of a series of numerical experiments and in proving their limiting aperiodic nature.

An analysis of the experimental data for the cases of a neutrally stable control object and an electromechanical system has been carried out. The performed study of third-order relay systems synthesized using the N–i switching method covers all possible options for the configuration of transition trajectories created by correcting the initial constraints of the canonical coordinates of the systems in order to ensure aperiodic entry into the sliding mode. The studied optimal control systems form transient processes with the desired character, which indicates the effectiveness of the created algorithm.
TO DETERMINATION OF SPEED AND TRACTION OF PARTICLE MOVEMENT IN THE HEAT FLOW
Authors: Sokolovska I. , Klimov R. , Morozovska A.
Published: June 2022

The article presents experimental data on the basis of which a mathematical model of particle motion in a vortex layer during heat treatment is created, taking into account changes in their sizes. The peculiarities of particle motion in the vortex apparatus are determined in the work. There is also a dependence that allows you to control the duration of heat treatment. Based on the results of research and modeling, you can design a device for drying dispersed particles.

The current level of development of vortex devices stimulates the relevance of research aimed at a deeper study of heat treatment processes, improving the design of devices and manufacturing technology of individual components. The lack of a strict modern theory is particularly acute in the design of systems and devices in which the vortex apparatus is one of the important units. In this regard, the priority today is to develop a theory that will provide a fairly reliable mathematical description of the processes occurring in the vortex chamber of the device.

In many fields of technology use different mass transfer devices for drying granular material for various purposes. In general, the methods of designing such devices are known, and if the technological process is implemented without any features, the calculation methods justify themselves. In cases where the properties of the material in the heat treatment process change, traditional calculation methods give significant errors. Then there is a need for mathematical modeling of basic technological processes.

In the hydrodynamics of the apparatus presented in the work, and accordingly in the processing, it is necessary to distinguish two main stages: pre-drying of particles in a flat jet of coolant and the final heat treatment in the vortex layer. In this paper, we dwelled in more detail on the first stage of technology.

The equations presented in this paper reflect the features of heat treatment of particles in the vortex apparatus taking into account their variable sizes and can complement the existing methods of designing such installations.

The equations obtained in this way reflect the above-mentioned features of heat treatment of particles in a vortex apparatus taking into account their variable sizes and can supplement the existing methods of designing such installations.

Published: June 2022

Nigeria is a country blessed with a vast variety of food items and cassava happens to be one of them. It is geographically widespread hence; it is very cheap. This research work revealed that cassava apart from consumption can also serve as an additive in cement slurry for well completion in oilfield operations after series of test was conducted in the laboratory on it. Tests such as rheology, free fluid, determination of slurry weights and stability at different temperatures ranging from 80°F to 190°F and concentrations was conducted using API procedure. The rheological properties, free fluid, slurry weights and stabilities at different temperatures and concentrations of starch were established and compared with the foreign sample and the results obtained proved that local cassava starch can be a substitute for foreign starch sample as it was seen to have similar rheological properties when compared with the foreign starch sample. The plastic viscosity and yield point values obtained from the rheological deductions for local starch compared favorably with the foreign starch. In terms of free fluid, zero free fluid is usually recommended for filed practice. Local cassava starch was seen to have 0 free fluid which means that this could be a substitute with the foreign starch. For the slurry weights, there were no significant difference between them. Therefore, from the research finding, locally produced starch especially POCEMA starch proved to have properties suitable for application in oil filed cementing operations as there was no significant difference between them when compared.

Published: June 2022

The Nigerian construction industry is faced with challenges of inadequate allocation of resources and mismanagement of budget toward housing provision. This has led to an alarming rate of the housing deficit, costly renting, repeated collapse of buildings, high rate of squatting, professional incompetence and increase in crime. This paper examines the problems and effects of annual housing budget allocation and Housing Provision in Enugu State, Nigeria. Secondary data were collected from experts working in state civil servants concerned with budgeting and housing matters in Enugu State. One hundred and forty-six (146) well questionnaires were properly completed, formed the basis of the study and were analyzed by descriptive ranking and factor analysis, SPSS and Relative Importance Index. The result from the study shows that there are problems in housing budget allocation and this affects its provision drastically; Ineffective mechanism for allocation and utilization of housing funds; Lack of citizen participation and professionals; Lack of accurate data on housing needs of the State and undue political influence in approval and award of housing contracts and a factor analysis was used in order to solidify result. The study finally recommended that government should give housing target to the housing agencies or developer in the state; should develop political will; establishment of building materials industries of its own and finally ensure that Quantity surveyors should be involved in the government policies for housing in order to manage and curtail unnecessary waste, cost and time in order to minimize the problems existing between housing budget allocation and its provision in Enugu state.

OBJECTIVE

The aim of this study was to analyze risk factors and avoidance techniques for proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) in the upper thoracic spine with an emphasis on bone mineral density (BMD) as estimated by Hounsfield units (HU).

METHODS

A retrospective chart review identified patients at least 50 years of age who underwent instrumented fusion extending from the pelvis to an upper instrumented vertebra (UIV) between T1 and T6 and had a preoperative CT, pre- and postoperative radiographs, and a minimum follow-up of 12 months. HU were measured in the UIV, the vertebral body cephalad to the UIV (UIV+1), and the L3 and L4 vertebral bodies. Numerous perioperative variables were collected, including basic demographics, smoking and steroid use, preoperative osteoporosis treatment, multiple frailty indices, use of a proximal junctional tether, UIV soft landing, preoperative dual-energy x-ray absorptiometry, spinopelvic parameters, UIV screw tip distance to the superior endplate, UIV pedicle screw/pedicle diameter ratio, lumbar lordosis distribution, and postoperative spinopelvic parameters compared with age-adjusted normal values.

RESULTS

Eighty-one patients were included in the study (21 men and 60 women) with a mean (SD) age of 66 years (6.9 years), BMI of 29 (5.5), and follow-up of 38 months (25 months). Spinal fusion constructs at the time of surgery extended from the pelvis to a UIV of T1 (5%), T2 (15%), T3 (25%), T4 (33%), T5 (21%), and T6 (1%). Twenty-seven patients (33%) developed PJK and/or PJF; 21 (26%) had PJK and 15 (19%) had PJF. Variables associated with PJK/PJF with p < 0.05 were included in the multivariable analysis, including HU at the UIV/UIV+1, HU at L3/L4, DXA femoral neck T-score, UIV screw tip distance to the superior endplate, UIV pedicle screw/pedicle diameter ratio, and postoperative lumbar lordosis distribution. Multivariable analysis (area under the curve = 0.77) demonstrated HU at the UIV/UIV+1 to be the only independent predictor of PJK and PJF with an OR of 0.96 (p = 0.005). Patients with < 147 HU (n = 27), 147–195 HU (n = 27), and > 195 HU (n = 27) at the UIV/UIV+1 had PJK/PJF rates of 59%, 33%, and 7%, respectively.

CONCLUSIONS

In patients with upper thoracic–to-pelvis spinal reconstruction, lower HU at the UIV and UIV+1 were independently associated with PJK and PJF, with an optimal cutoff of 159 HU that maximizes sensitivity and specificity.
Creative economy of the paternalistic state: What does the coming day hold for us?
Authors:   Institute of Economics, Russian Academy of Sciences, Moscow, Russia, Rubinstein А.Ya.
Published: June 2022

The paper presents the author’s view on the formation of economics of culture which was acceded to the neoclassical theory as a branch science only in the second half of XXth century with the inherent law of «price disease» causing deficiency of income of cultural goods producers. The present stage of the development of this science is determined by the modern theory of economic growth where the hypothesis of dependence of total factor productivity on intangible assets is presented as an innovation allowing discovering inner resources of culture and other creative economy branches which fundamentally change their position in the economic world. The question is about the economic valuation of the results of cultural activity, including copyrights that were transformed into intellectual property. At the same time, the article formulates a contrary assessment of the concept of cultural industries, which can only become an additional reason for the financial authorities to reduce the amount of budget subsidies to producers of cultural goods.

Authors: Hristova Irinka , Georgieva Despina , Koleva Greta
Published: June 2022

Introduction: Misinformation and fake news feed the fears that many people have of the approved vaccines against Covid-19 around the world. In Bulgaria, it is no different. The latest statistics indicate Bulgaria as the EU country with the lowest percentage of adults with completed vaccination status. To date, the cumulative number of confirmed deaths since the beginning of the COVID-19 pandemic has exceeded 26,000. Aim/Objective: This report presents an analysis of the results of a study of attitudes towards Covid-19 vaccination in Ruse district, Bulgaria. Material and Methods: The survey was conducted in the period October 25 - November 14 2021, and covered 549 adults. Despite the high levels of information awareness in Bulgaria, a low vaccination rate has been reported. Results: Of all respondents, only 26.0% (143 n) were vaccinated against Covid-19. At the time of the survey, there were no national orders for a mandatory EU COVID Certificate required for all indoor activities. Discussion: What is really worrying is the fact that 4.9% (20 n) of unvaccinated respondents openly state that they will find a way to buy a fake EU COVID certificate if it becomes mandatory. This intention has been reported across all age groups, working-age population, and mainly among those living in cities and with completed secondary education. Conclusion: In our opinion, increasing the control over the issuance of COVID vaccination certificates and respectively, eliminating the possibility for issuing fake ones should be a national policy for our countr

Introduction: Intimate partner violence (IPV) is an important public health problem. However, its prevalence varies by country and culture. Aims: To estimate the prevalence of IPV, determine its types and risk factors, and to assess the attitude of women towards IPV in Al-Madinah City, Saudi Arabia. Methods: A cross-sectional study was conducted. A convenience sample that included 450 ever-married women aged 18- 65 years and lived in Al-Madinah city, Saudi Arabia in 2021 was used. The data were collected online through Social media using an Arabic validated version of the WHO questionnaire on women’s health and domestic violence against women. Data about socio-demographic and violence-related factors were collected. The prevalence of IPV was assessed and its associated risk factors were examined using multivariate logistic regression analysis. Results: The prevalence of IPV against women was 37.6%. The prevalence was significantly higher among older, divorced, and less educated women, and presence of another husband’s wife. The main types of violence reported by abused women were “pull hair up” (47.3%) and “throw household items” (41.4%). A higher significant risk of IPV was found among women with husbands’ aged > 50 years (OR= 4.6), divorced women (OR= 12.5), and presence of another husband’s wife (OR 4.1). The agree attitude of the studied women towards violence causes was the highest for “Betrayal” (23.5%). Conclusion: The prevalence of IPV against women is relatively high in Al-Madinah city. Age and education of women and husbands, marital status, and presence of another husband’s wife were the most important risk factor

Published: June 2022

Introduction: Type 2 diabetes is a severe disease. It contains hormones that produce certain metabolic abnormalities and long-term problems. Urine contains low but abnormal levels of albumin which is the initial stage called “microalbuminuria”. Aim: To examine the association between dyslipidemia and diabetic nephropathy in type 2 diabetic patients. Methodology: Overall, 110 type 2 diabetic patients were involved in this study. Their detailed clinical history was evaluated along with clinical examination, urine albumin creatinine ratio, serum lipid profile. Data was analyzed using the Chi-square test and ANOVA test. It was done by the software EPICAL. A p-value less than 0.05 was considered significant.Study design: A cross-sectional study. Place and duration: This study was conducted at Bilawal Medical College for Boys at LUMHS Jamshoro Pakistan from June 2020 to June 2021. Results: A total of45 patients were having normoalbuminuria, 25 were having overt proteinuria, and the rest 40 patients had microalbuminuria. The most significant lipid abnormalities found in this study was increased LDL and increased triglyceride. Patients having Normoalbuminuria and overt proteinuria were compared and it was found that LDL and triglyceride had a positive correlation. As triglycerides increased, LDL also increased. Both had a p-value <0.001. Conclusion: Lipid abnormalities associated with diabetic nephropathy were increased low-density lipoprotein (LDL) and triglyceride.

On the particularities of Russian assistance to the development of Central Asian countries
Authors: Romanchuk Ekaterina
Published: June 2022

The article reveals various aspects of interstate cooperation within the frame of the Russian Federation's assistance to the development of the Central Asian republics in the context of both bilateral and multilateral relationships, with the involvement of international institutions (UNDP and the World Bank) as agents, and without them. Based on this, the author concludes that the thesis about the lack of necessary financial resources to maintain Russia’s influence in the region is not supported by actual data. The misconception about the insignificance of the volume of Russian aid stems mainly from the inefficiency of its use and as a result of incorrect reflection in OECD statistics.
A Novel Human-Awareness Solution for Person-Following Robot’s Behavior Problem Based on Proxemics

Published: June 2022

Soon robots will cooperate with humans in everyday tasks. These robots must be endowed with social skills so that their behavior will be similar to that of people. One of these behaviors is navigation: how the robot plans the route and moves through ubicomp environments. For example, a social behavior during navigation consists of detecting the position of people and evaluating with proxemics those areas where the robot can move and with what velocity. This work presents a new controller for the following ability of a socially aware person. The robot is equipped with RGB-D and laser sensors and navigates through an ubicomp environment that provides the person’s position at every moment. The system initially estimates the person’s position and its interaction regions at a future instant and then adjusts its path and velocity based on this estimate. Experimental results in simulated environments are included and discussed as initial results to show the performance of this proposal. We include a set of social metrics to validate the proposed results.
On the Application of Unsupervised Clustering to Sound Pressure Data from an Acoustic Sensors Network
Authors: Pita Antonio , Rodriguez Francisco J. , Navarro Juan M.
Published: June 2022

Many cities around the world are deploying wireless sensor networks to capture information on different environmental parameters. Noise, as one of the main pollutants with negative effects on health and economy, is monitored through sound pressure level. In this work, the application of unsupervised clustering to sound pressure level data from a wireless acoustic sensors network (WASN) is proposed. Data from a sensor network deployed in the city of Madrid are used to show the usefulness of performing a clustering process with the aim of detecting different patterns of behavior of noise levels. The preliminary results obtained have allowed us to divide the city into several acoustic zones, which help city managers to propose improvement plans.
