What do we know about our professional self-government of nurses and midwives? Preliminary study
Authors: Kolbe Gilbert , Kryczka Tomasz 
Published: March 2021

Abstract

Introduction. Professional self-government is a form of association of persons who practice the same profession, established in order to represent their interests against the state authorities.

Aim. The aim of this study was to assess the knowledge of nurses and midwives on their professional self-government and their engagement in its activity.

Material and methods. The study was conducted among 1,143 nurses and midwives. An originally designed questionnaire was used. The survey was administered via the Internet. Findings from questionnaires completed by 895 members of the Warsaw Regional Chamber of Nurses were analysed statistically. Statistical analysis was performed using intergroup comparisons or interfactor correlation tests, depending on the type of variables; statistical significance was set at p≤ 0.05.

Results. Nearly 3/4 of respondents had low-to-medium knowledge on their professional self-government. Age and career length were positively correlated with a high level of knowledge.

Conclusions. The knowledge of nurses and midwives on their professional self-government and news related to its functioning should be considered unsatisfactory and fragmentary. Further studies to determine the way to convey this knowledge to nurses and midwives are needed in order to expand this knowledge.
Worldwide Disease — Haemorrhoids. How Much Do We Know?
Authors: Fišere Inese , Groma Valērija , Goldiņš Niks Ričards , Gardovskis Andris , Gardovskis Jānis 
Published: March 2021

Abstract
Haemorrhoids are highly vascular cushions of connective tissue in the anal canal, which are normal structures of the human body. Haemorrhoidal disease in clinical practice means that there is an abnormal enlargement of the anal cushions when these transform into “anal nodules”, bleed and/or prolapse. Haemorrhoidal disease is very common. Despite numerous studies undertaken and knowledge accumulated on the aetiology and pathogenesis of haemorrhoidal disease in the last decade, the specific mechanisms responsible for the development of the disease are not thoroughly understood. The pathophysiology is most likely multifactorial and complex, manifested by muscle weakness, intrarectal prolapse, changes in vascular pressure and flow in blood vessels, malformations, sphincter damage and failure, venostasis, inflammatory reactions, endothelin and collagen abnormalities, matrix metalloproteinases activity, etc. Currently, treatment guidelines for the haemorrhoidal disease are based on Goligher’s classification. The classification of haemorrhoidal disease should be submitted to revision by including aetiological factors, the dynamism of prolapse, symptomatology, enteropathogenesis, and gender characteristics. The present review is focused on recent data gained by exploring the anatomy, pathophysiology, classification, theories explaining the development of haemorrhoids, as well as aetiological invasive and surgical treatment modalities.

Abstract

OBJECTIVE. To describe the results of tracheostomy in a series of cases in patients with COVID-19 admitted to the intensive care unit in two hospitals in the Northwest Mexico.

MATERIAL AND METHODS. A prospective, descriptive, longitudinal study was carried out on a series of cases from April 2020 to August 2020. Data such as age, sex, hospital of origin, risk factors for the development of severe COVID-19, ventilatory and gasometric parameters before and 72 hours after, the days of oro-tracheal intubation were taken into account. Descriptive statistics with frequencies and percentages were used for the qualitative variables, for the numerical measures of central tendency as the mean and the median, the distribution of the results.

RESULTS. From April to August 2020, in the two Intensive Care Units (ICUs) of these hospitals, 134 COVID-19 cases were admitted. In 14 patients (10.4%) tracheotomies were performed, 13 (92.8%) were male, mean age 49.21 years, 85% tested positive. The mean duration of oro-tracheal intubation was 22.7. Obesity combined with diabetes and arterial hypertension represented a risk factor in 57.1% of the cases. In 10 patients, the procedure was performed in the ICU bed. There were changes in some ventilatory parameters before and 72 hours after the procedure. The average number of days after weaning from the ventilator was 5.5 days. There were 3 deaths in our series.

CONCLUSION. The adequate and prudent selection of COVID-19 patients for tracheostomy makes it easier to choose with greater justification the patients with the best prognosis, avoiding unnecessary procedures in a patient and a greater risk of contagion in the personnel.
Science and Religion Shift in the First Three Months of the Covid-19 Pandemic

Published: March 2021

Abstract
The goal of this pilot study is to investigate expressions of the collective disquiet of people in the first months of Covid-19 pandemic, and to try to understand how they manage covert risk, especially with religion and magic. Four co-authors living in early hot spots of the pandemic speculate on the roles of science, religion, and magic, in the latest global catastrophe. They delve into the consolidation that should be occurring worldwide because of a common, viral enemy, but find little evidence for it. They draw parallels to biblical works, finding evidence of a connection between plague and “social strife.” They explore changes in the purviews of science, religion, and magic, and how and why they have changed, as three systems of covert risk management. They speculate on the coming wave of grief when the world populations finally decide that too many people have died, and they envision cultural changes on the other side of the pandemic, to lifestyles, travel, reverse urbanization, and living and working in smaller communities. Using an unusual approach named “crowd-sourced ethnography”, they conduct un-traditional ethnography and speculate on management of covert risk in their native countries.
Energy Demand and Cooking Energy Cost in an Oil-Rich Economy: A New Evidence from Nigeria

Published: March 2021

Abstract
According to several recent studies, energy is seen as a commodity, due to the fact that energy sector markets are more like commodity markets. Essentially, it serves as an enabler of social and economic development and so cannot be neglected. This study, therefore, estimated the impact of cooking energy cost on energy demand in Nigeria using the ARDL model and quarterly data spanning from 1990-2018. The result from the study showed that in the long-run both liquefied petroleum gas (LPG) price and kerosene price has a negative impact on energy demand. In the short-run, the result remained the same for kerosene while it reversed for LPG. The study, therefore, recommended that government should enact policies that will moderate or minimize the cost of cooking energy and enhance the removal of all forms of barriers in making cooking energy affordable to users in the country.
Exploring the Effects of Psychological Factors on the Use of Navigation Systems While Driving

Published: March 2021

Abstract
The ever-increasing use of private vehicles makes Advanced Driver Assistance Systems (ADAS) more necessary as they improve users’ convenience, safety and travel time. Although these systems offer significant advantages, they call into question the traditional role of users, making the psychology of drivers towards these technologies a necessary factor for their adoption. The purpose of this paper is to investigate the effects of psychological factors on the use of one of the most widely used ADAS, the Global Navigation Satellite Systems (GNSS). Towards this direction, a literature review was conducted to identify the factors that influence drivers’ behavior and the psychology of drivers towards new technologies. Furthermore, a questionnaire survey was organized in Greece, based on the Theory of Planned Behavior, including additional variables, which were identified in the literature, such as technophilia, trust in technology and endorsement. From the data collected, models predicting the behavior of drivers were developed through structural equation modelling, concerning the use of navigation systems in both urban and interurban networks. The findings of the research reveal that the intention to use a navigation system is determined by various factors such as behavioral beliefs about its usage, normative beliefs and technophilia. The actual use of a navigation system depends to some extent on this intention.

Published: March 2021

Hydroxychloroquine (HCQ) is a quinoline derivate used for the treatment of malaria and rheumatoid disorders. During early phases of the SARS-CoV2 (COVID-19) pandemic, preliminary and later not substantiated reports suggested that HCQ might benefit COVID-19 patients. This had sparked a worldwide and rapidly rising demand for HCQ drug products. Consequently, patients with pre-existing rheumatic diseases in Switzerland were confronted with an acute drug shortage.We have therefore designed, produced and characterized a generic HCQ drug formulation. The proposed HCQ formulation can be manufactured by using a minimal number of operation steps (mixing, wet granulation, sieving, blending, compression) and readily available pharmaceutical excipients.HCQ tablets were manufactured by granulation of the active pharmaceutical ingredient (API), blending with the external phase and compaction using a non instrumented single punch tablet press. Analytics and identification of the API was performed by a combination of NMR, ESI-MS, FTIR and HPLC. HCQ tablets met the quality criteria for an immediate release HCQ dosage form.We hope that free access to non-proprietary protocols covering analytical procedures, formulation design, and manufacturing instructions for HCQ tablets will help to bridge existing and future supply chain gaps.
Analytic Gradients for Complete and Restricted Active Space Second-order Perturbation Theory within the Diagonal Approximation
Authors: Nishimoto Yoshio 
Published: March 2021

The computational cost of analytic derivatives in multireference perturbation theory is strongly affected by the size of the active space employed in the reference self-consistent field calculation. To overcome previous limits on active space size, the analytic gradients of single-state complete and restricted active space second-order perturbation theory within the diagonal approximation (CASPT2-D and RASPT2-D) have been developed and implemented in a local version of OpenMolcas. Similar to previous implementations of CASPT2, the RASPT2 implementation employs the Lagrangian or Z-vector method.The numerical results show that restricted active spaces with up to 20 electrons in 20 orbitals can now be employed for geometry optimizations.

Published: March 2021

Objective ‒ to develop a technique for endovascular treatment of symptomatic ostial stenosis of the vertebral arteries, which allows to minimize risks of delayed stent breakage and restenosis. Materials and methods. This is analysis of prospectively collected data from patients presenting from 2016 to 2019 in the endovascular center of the Dnepropetrovsk Regional Clinical Hospital named after I.I. Mechnikov. One hundred four stents were placed in 99 patients using the author’s complex method, which is based on our modification of Szabo technique. The principles of the method were developed based on a literature review and in vitro tests using 7 silicone models of the initial segments of the subclavian and vertebral arteries with different angles of divergence of the vertebral arteries (30, 45, 60, 90, 120, 135, 150°) and 9 balloon mounted drug-eluting stents with open-cell design Resolute (Medtronic).Results. There were no cases of displacement of the stent proximally or distally during implantation. In all cases, stents were implanted in the affected segment exactly and did not prolapse more than 1 mm beyond the ostium of the vertebral artery into the subclavian artery. There were no «clinical» ischemic complications in the early postoperative period. In 5 cases, isolated subclinical ischemic lessions in the carotid circulation were revealed during one-session stenting of ostial stenosis of the vertebral arteries and carotid stenting. In the posterior circulation, ischemic lessions on MRI in the early postoperative period were not detected in any observations.Conclusions. Developed complex stenting method based on our modification of Szabo technique allows us to achieve optimal long-term results of stenting of symptomatic ostial stenosis of the vertebral arteries.
