Authors: Denine P. P.
Published: September 2021

In March 1921, a sick peasant woman was admitted to the Hospital Surgical Clinic with complaints of hematuria, which appeared 3-4 days after a slight malaise. The rest of the patient felt healthy. Objectively, the patient did not represent any deviation from the norm. In particular, her t is normal, there are no symptoms of scurvy. For hematuria, cystoscopic examination. Cystoscopy revealed: the orifices of the ureters are normal, on the normal mucous membrane there are scattered red spots the size of a pinhead and larger, very similar to flea bites; these specks are scattered in various parts of the bladder, mainly at the bottom of it; there are no infiltrates around the spots and other changes.

Electronics improvements for low-level control in the humanoid robot TEO
Authors: García Haro Juan Miguel , Oña Edwin Daniel , Santos Rico Raul de , Martínez Santiago , Balaguer Carlos
Published: September 2021

This work began with developing the first electronic integration to allow the operation of commercial TEO devices pre-selected. However, different problems were discovered during the implementation of the whole set. These were caused by the malfunction of the system and the particular design. For this reason, this paper is focused on the analysis of the first hardware architecture to propose and develop a solution that improves the performance of the joint motor control.Significantly, the detected problems are voltage drops in the power supply signals of some devices, electrical noise coupling or overshoots produced by the switching of the power inverter of the driver, and the electromechanical disconnections of various signals caused by the relative motion between devices. The consequence was that the robot joints control was not robust, preventing them from moving accurately. After the analysis, new interconnection electronics was developed. This electronic has been designed to be more integrated with the mechanic parts, improving subsystems location, and integrating new solutions to reduce the electrical problems. The new electronics have been tested in the humanoid robot arms with good results.

INTRODUCTION: Drug abuse is a significant contributor to premature disease and mortality. Drug users are less likely to attend traditional Primary Health Care and more likely to present to Emergency Departments with their problems. Drug users often present late for treatment and find difficult ot engage and follow through treatment in standard models of health services. Materials and methods: The study is retrospective. 108 intravenous drug users were identified upon admission to one of three intpatient addiction treatment centres in Iceland in the years 2012-2013. Case notes for the two years leading to admission were examined. Results: The study group had significantyl more contacts with Emergency Departments than a matched sample from the community (p<0.001). Mean number of visits for the study group per year was 4.8 (median 3.5) and 43% had four or more visits in a year. Majority of visits were for pshychiatric symptoms with a third considered serious. The two main medical reasons were infections from injecting and accidents/violence. There was no significant difference in study parameters between those who mainly use methylphenidate vs other substances. Mortality rate for the study group compared to the general population of same age was 26.4 (CI 16.7-41.5, p<0,001).

Authors: Ellis Katie , Kent Mike , Locke Kathryn , McRae Leanne , Dau Duc , Peaty Gwyneth
Published: September 2021

This paper offers insight into and analysis of the disparate and diverse experiences of Australians with disability, at the intersections of technology and geography during the COVID-19 pandemic.Drawing on interviews with the blind and low vision community we identify a significant cross-generational uptake of smartphones. Participants demonstrate a reflexive and creative use of these devices when faced with reduced accessibility, and the significance of geography – not simply the distinctions between countries, but between urban and regional residents.These interviews are contextualised within a broader discussion of how Australians with disability responded to the pandemic via analysis of blogs, articles and social media. We focus on the voices and perspectives of disabled people, and that community's emphasis on individuality and intradisability diversity.Lastly, we present an overview of the discussions being held around the role of contact tracing and apps, privacy, validity and vulnerability. This discourse is important for ensuring support for the disability community pre and post global health emergencies, but also a valuable exemplar for understanding the relationship between digital inclusion and social equality more broadly.

Authors: Jayashree Venkata , Renuka Lakshmi
Published: September 2021

Background: Preeclampsia is a dangerous complication which occurs potentially in pregnancy and is characterised by high blood pressure. It effects maternal and perinatal health and is complicated by abnormalities of coagulation. The aim of the study was to determine platelet count which predicted coagulopathy in patients with severe preeclampsia and eclampsia.Methods: Prospective cohort study done in all patients were admitted with diagnosis of severe preeclampsia and eclampsia and admitted for stabilisation.  Blood samples were collected from all patients for detecting bleeding, clotting time, electrolytes, urea and creatinine, liver functions tests, full blood count, platelet count, prothrombin time, activated partial thromboplastin time and plasma fibrinogen level in 100 patients in total. Using chi square test, univariate analysis was conducted.Results: Out of 100 women patients, 70 (70%) patients had severe preeclampsia and 30 (30%) patients had eclampsia out of which 15 patients had thrombocytopenia. The incidence of thrombocytopenia among patients was 16.6%. Biochemical coagulopathy was noted in 7%. Patients with severe preeclampsia had platelet count of 185000±61289 per µl, PT was 13.52±1.48 sec, APTT was 34.52±2.49 sec and fibrinogen was 3.16±0.22 g/dl. Patients with eclampsia (with thrombocytopenia) had platelet count of 79528±14897 per µl, PT was 19.25±5.28 sec, APTT was 37.08±5.33 sec and fibrinogen was 2.67±0.53 g/dl. Thrombocytopenia was complicated with eclampsia and it was associated with biochemical coagulopathy which made the condition more severe.Conclusions: 80000 cells/µl is the thrombocytopenia level which is considered to be critical in severe preeclampsia and eclampsia. This will help to reduce maternal and perinatal mortality and morbidity rates.

Crowns are used to manage many issues related to the primary teeth as pulpal therapy, such as developmental defects, restorations, fractured teeth, in cases of increased risk of severe dental caries, increased risk of failure of direct restorations. It also can be used as space maintainers abutments, and in cases where extensive tooth wear was present. Among the variously reported crowns, zircona, and stainless-steel crowns are commonly used in clinical settings. In this literature review, we have discussed the clinical outcomes, efficacy, stainless steel crowns, and other parameters for zirconia in pediatric patients. Many advantages and disadvantages were reported for both modalities among studies in the literature. The main disadvantage of using stainless steel crowns is their associated poor esthetic problems. However, the previous issues with their potential toxic effects have been resolved as a result of the recent metallic composition of these crowns. On the other hand, zircona crowns have been reported with many favourable clinical outcomes and increased parent satisfaction. Nevertheless, high cost and increased operation time might be the only limitations for using these modalities in clinical settings.

Published: September 2021

Serous effusion cytology being a minimally invasive, readily accessible and inexpensive diagnostic procedure. Nevertheless, the accuracy of SEC could vary widely due to the multitude factors including the level of experience of the cytologists Conventional smear has its own limitations with varied efficacy and hence warranting ancillary studies. Cell block has emerged as a paramount and robust platform for sample processing techniques in cytology. Research studies have proved that the efficiency of cytological diagnosis increases by significant margin of 15-20 percent when it is done in conjunction with cell block techniques especially in cases of exudative fluids in picking up crucial cases and based on this, we intended with a novel aim to analyse the accuracy of Serous effusion cytology by combining conventional smear and cell block technique with an attempt to assess the effectiveness of the cell block by our indigenous Modified Bouin’s method.

Cell block method prepared by our indigenous Modified Bouin’s preparation with formalin fixative proved to show high quality significance and hence it could be followed in routine practice across laboratories. Cell block technique is quantitatively superior both standalone as well as in conjunction with conventional smear by improving the effective diagnosis of SEC. Diligent use of cell block technique eliminates the suspicious of malignant category on CS and thereby giving more definite diagnosis and thus it is mandated that combined approach of CB in conjunction with CS should be practiced as binary protocol which proved to have obvious influence on patient management.

Published: September 2021

Previous studies have demonstrated that cancer cells harbor unique metabolic characteristics relative to healthy counterparts. The current study is a prospective ex-vivo HR-MAS NMR analysis of malignant colorectal cancer (CRC) tissue specimens and its corresponding benign tissues.

To assess the HR-MAS Spectroscope qualitatively & to analyze significant difference between the normal, benign and malignant intestinal mucosa.

Between November 2013and January 2016, 36 consecutive patients with confirmed CRC were recruited to a prospective observational study. Fresh tissue samples were obtained from center of tumor and 5 cm from tumor margin from surgical resection specimens. Samples were run in duplicate where tissue volume permitted to compensate for anticipated sample heterogeneity. Typically, the sample was packed into a 4 mm ZrO2 rotor of 50 μl capacity; a volume of 20μl of D2O having 0.03% TSP was used as a chemical shift reference. The sample-rotor-setup was then transferred into the HR-MAS NMR probe for analysis.

A total of 36 spectra were acquired (center of tumor, n = 18; 5 cm from tumor margin, n = 18). The malignant clustering occurs due to increased Val (0.90ppm), Lac (1.34ppm), Ala(1.48ppm) levels of acetate (1.90ppm), glutamate (2.35ppm), taurine (3.23 ppm), choline containing compounds (3.20-3.22ppm), glycine (3.56ppm), lactate (4.12ppm) and α-H of Leu, Ileu, Val, Lys, Ala (3.76-3.79ppm . In addition unique metabolic profiles were observed for tumors of differing T-stage. The information gathered from clustering in PCA had highly suggested that malignancy induces metabolic perturbations at cellular levels.

HR-MAS NMR profiling demonstrates cancer-specific metabolic signatures in CRC and reveals metabolic differences between benign and malignant tumors. In addition, this approach reveals that tumor metabolism undergoes modification during local tumor advancement, offering potential in future staging and therapeutic approaches.

Placental mesenchymal dysplasia is a rare disorder mainly characterized by enlarged placenta. Patients on antenatal visits present with normal or slightly raised Beta-HCG, raised Alfa-fetoprotein and cystic structures on USG resembling a molar pregnancy. It has to be differentiated from molar pregnancies to avoid unnecessary termination of pregnancy. This condition is associated with IUGR or IUFD. Mostly the fetus are females. Due to lack of awareness of this condition it remains underreported. Here we present a case report of 20 years old female 37 week pregnant with IUGR with clinical suspicion of molar pregnancy gave birth to alive female fetus and on histopathological examination of placenta was diagnosed with PMD.

Authors: Oviedo Daniel , Perez Jaramillo Daniel , Nieto Mariajosé
Published: September 2021

This paper seeks to shed some light on the different considerations for regulation and governance of ride-hailing platforms in emerging markets, highlighting their positive and negative externalities. Building on an extensive review of the literature and secondary sources, we outline Ride-hailing's identified and potential effects on users (providers and consumers), incumbents, and society. Based on the welfare impacts structure, we identify the significant challenges that regulators face in understanding, monitoring, evaluating, and regulating this type of transportation innovation. Finally, the paper proposes a framework for approaching such mobility innovations from governance and regulation perspectives. In a context of exponential growth in research and innovation in urban mobility in general and Ride-hailing, a rigorous review of the literature and a critical framework for understanding governance and regulation in such services in rapidly changing contexts is a timely contribution.
Text Analysis of Project Completion Reports
Authors: Montiel Olea César E. , Corral Leonardo R.
Published: September 2021

Project Completion Reports (PCRs) are the main instrument through which different multilateral organizations measure the success of a project once it closes. PCRs are important for development effectiveness as they serve to understand achievements, failures, and challenges within the project cycle they can feed back into the design and execution of new projects. The aim of this paper is to introduce text analysis tools for the exploration of PCR documents. We describe and apply different text analysis tools to explore the content of a sample of PCRs. We seek to illustrate a way in which PCRs can be summarized and analyzed using innovative tools applied to a unique dataset. We believe that the methods presented in this investigation have numerous potential applications to different types of text documents routinely prepared within the Inter-American Development Bank (IDB).
Emergency Medicine Shift Factors Causing the Most Stress Among Emergency Medicine Residents
Authors:   University of Toledo College of Medicine and Life Sciences, Moussa Mohamad
Published: September 2021

Introduction: Past studies demonstrate that stress and anxiety affect emergency medicine physicians, but the causal factors identified are usually from sources outside the work shift. We attempt to show the relationship between intrinsic factors of a work shift and anxiety perceived by residents, while also examining differing gender responses. Methods: In 2018, a cross-sectional survey of emergency medicine residents in the United States was distributed anonymously through the Emergency Medicine Residents Association. The survey consisted of demographic questions, novel questions identifying intrinsic factors, and the Generalized Anxiety Disorder 7-item (GAD-7) scale. Spearman correlation, independent t-test, and multivariate analysis of variance were performed. Results: Data from 573 residents found several stressful factors: working with a nurse perceived to be inefficient, working with no inpatient beds available, and working with a colleague perceived to be inefficient. The majority of respondents reported some general anxiety on the GAD-7 assessment. There was no difference on anxiety level as a function of year of residency (p > .05). There was a significant gender difference on anxiety level, t(571) = -4.8689, p < .05, where male residents reported lower anxiety levels (mean=5.15) as compared to female residents (mean=7.02). Lastly, post-hoc analyses revealed that male and female respondents reported differing levels of stress in response to several intrinsic stress factors. Conclusion: We identified several intrinsic factors during a shift that contribute to resident anxiety and analyzed differing gender responses to these factors; this may provide a framework for residency programs to minimize stressors in the future.
STATISTICAL CHARACTERISTICS OF DAILY AMOUNTS OF ATMOSPHERIC PRECIPITATION ON THE TERRITORY OF THE ODESSA REGION IN THE CONDITIONS OF GLOBAL CLIMATE CHANGE
Authors: Prokofiev O. M. , Goncharova L. D.
Published: September 2021

Problem Statement and Purpose. Rational use of nature, solution of natural and environmental problems, planning and location of various sectors of the economy are based on climatological information. As empirical data accumulate, some values, as well as the probabilistic characteristics of climate-relatednatural resources, need constant refinement due to the fact that hydrometeorological phenomena are extremely variable in time and space. Of great practical interest is information on daily and maximum rainfall and therefore there is a need for their comprehensive analysis, study and forecasting.
Data & Methods. The initial information for estimating the precipitation regime is the term data for 00, 06, 12 and 18 hours at nine stations of Odessa region in the period 2010–2015, to which a number of general scientific and statistical methods were applied.
Results. Some indicators of the precipitation regime, which are widely used in scientific and practical developments, are analyzed. The total number of days with precipitation and their recurrence are determined. For the territory of the region it is 34.4%. The most days with precipitation were observed in January, and the least – in August, except for Art. Calm, at which the minimum number of days with precipitation was recorded in November. The frequency of precipitation of different gradations was studied and significant precipitations were analyzed: 10, 20, 30 mm and more per day. The region is dominated by precipitation up to 10.0 mm, the frequency of which ranges from 86% (station Rozdilna) to 91.4% (station Odessa). The maximum frequency of days with precipitation of 30 mm or more per day falls on the warm season (April-October). The fields of daily maximum of 1% and 5% probability are heterogeneous and at some stations of Odessa region the values of this indicator exceed the climatic norm (up to 10–12 mm), at others – less than the norm. The obtained results are a certain contribution to the study of both theoretical and practical aspects of the study of daily amounts and daily maximum precipitation, which are indicators of the regional climate. They can be used to make a climatological forecast, which is necessary for a more complete development of climatic resources of Odessa region.

Authors: Bitar Zeinab , Haddad Chadia , Obeid Sahar , Hallit Souheil
Published: September 2021

Background: The patient's evaluation of treatment and its associated outcomes define the treatment satisfaction. The quality of treatment satisfaction and healthcare service has been affected by depression, anxiety and fear of the current coronavirus disease 2019 (COVID-19) pandemic.

Objective: Therefore, this study aimed to assess factors associated with treatment satisfaction among Lebanese inpatients with schizophrenia, namely depression, anxiety and fear of COVID-19.

Methods: A cross-sectional study was conducted between September and November 2020, enrolled 118 patients with chronic schizophrenia consecutively admitted to Psychiatric Hospital of the Cross, Lebanon. The Functional Assessment of Chronic Illness Therapy-Treatment Satisfaction-Patient Satisfaction Scale (FACIT-TS-PS) was used to assess treatment satisfaction, the Lebanese Anxiety Scale -10 (LAS-10) was used to assess anxiety, Montgomery-Asberg Depression Rating Scale (MADRS) to assess depression and the Fear of COVID-19 Scale to assess the level of fear of the COVID-19 pandemic.

Results: The mean scores of the scales were as follows: treatment satisfaction (65.20; SD 16.11; median=71), LAS-10 (13.65; SD 6.02), MADRS (9.09; SD 6.69) and fear of COVID-19 (18.59; SD 6.78). Higher depression (r= -0.46, p<0.001) was significantly associated with lower treatment satisfaction. Female gender (beta=7.51, p=0.029) was significantly associated with higher treatment satisfaction score. Fear of COVID-19 did not show any significant association with the treatment satisfaction score.

Conclusions: Results of this study found that depression and gender were associated with treatment satisfaction among inpatients with schizophrenia. No association has been found between fear of COVID-19 and treatment satisfaction among those patients. More research is warranted to evaluate treatment satisfaction and associated factors among chronic inpatients with schizophrenia, specifically during the COVID-19 pandemic, in order to improve treatment satisfaction and subjective well-being of patients.

Graphs where Search Methods are Indistinguishable
Authors: Krnc Matjaž , Pivač Nevena
Published: September 2021

Graph searching is one of the simplest and most widely used tools in graph algorithms. Every graph search method is defined using some partic-ular selection rule, and the analysis of the corre-sponding vertex orderings can aid greatly in de-vising algorithms, writing proofs of correctness, or recognition of various graph families. We study graphs where the sets of vertex order-ings produced by two di˙erent search methods coincide. We characterise such graph families for ten pairs from the best-known set of graph searches: Breadth First Search (BFS), Depth First Search (DFS), Lexicographic Breadth First Search (LexBFS) and Lexicographic Depth First Search (LexDFS), and Maximal Neighborhood Search (MNS).

Early detection is critical for prevention of intellectual disability. Standardized newborn screening can have a positive impact on cognitive development in infants with CH.
The Application of Trauma-Informed Care to Substance Use Disorder
Authors: Maguire Denise J. , Cirrito Barbara L. , Solomon Jayne
Published: September 2021

Trauma-informed care (TIC) has been described to apply to several groups of traumatized patient/families in the NICU. Trauma is multidimensional, including physical and psychological injuries with long-term effects on well-being and function. A newborn experiences the best outcomes when the mother also experiences the best outcomes. Thus, the TIC approach is applicable to the care of the infant with neonatal abstinence syndrome (NAS) and mother. Organizational adoption of this model is likely to provide a supportive and therapeutic environment for the infant with NAS and family.

Published: September 2021

Background and Purpose

This study explored the psychometric properties of the Creighton Competency Evaluation Instrument (C-CEI), previously validated for use with nursing students, to assess simulation performance among registered nurses working 12-hour shifts. Valid and reliable measurements are needed to test clinical and simulation competencies and characterize the effects of fatigue on nursing performance.

Methods

Trained raters scored nurses’ patient care performance in simulation scenarios using the C-CEI. We analyzed the instrument’s principal components, internal reliability, and construct validity.

Results

Internal reliability of the C-CEI aggregate score and the Clinical Decision-making component were high (>.70). The latter robustly correlated with predicted cognitive effectiveness, a measure of fatigue.

Conclusions

The C-CEI is a reliable measure for use among registered nurses and its further development will be important for testing performance of working nurses and fatigue-mitigation innovations.

The HSCL-24/Nepali version is reliable and valid and can be used to culturally, appropriately assess psychological distress of Bhutanese refugees as it omits item 14 that captures individual’s sexual interest.
Study of influence of rolling stock vibration on signal of distributed optical sensor by means of numerical modeling
Authors:   Ural state university of railway transport (USURT), Galinurov Rishat Zinfirovich
Published: September 2021

The paper is devoted to possibilities of application of a distributed optical sensor on the railway transport as a mean of rolling stock position control. The paper proposes numerical modeling of a signal of a phase-sensitive reflectometer for assessing influence of moving rolling stock vibration. A theoretical description supposes that the external vibrational influence creates an area of elastic deformation of a light wave guide cable and causes changes of phase relations of scattered radiation. As a result, the author presents that the frequency and the amplitude of the applied vibration affect to a greater extent on the signal of the distributed optical sensor.

Published: September 2021

The method of unloading and reloading solidified oil fuels, with the use of pipelines made according to temporary technological schemes, produced in winter, is considered. Cooling of solidified fuels is accompanied by a sharp increase in their viscosity, which makes pipeline transmission impossible. In fire hazard, it is proposed to produce continuous heating of the pumped fuel using devices based on low-temperature combustion of propane-butane mixture on the surface of the catalyst carried out at fire-safe temperatures. It is also proposed to install a temporary heat-insulating shell on the pipeline that meets the operating modes of the heaters.
Simulation of an ac electric locomotive operation in the regenerative braking mode
Authors:   Irkutsk State Transport University (ISTU), Tomilov V. S.
Published: September 2021

Regenerative braking is one of the most important energy-saving resources on electric rolling stock (EPS) of railways and feasibility of its use is confirmed by a rich half-century history. The development of the recovery mode begins with the release of the experimental AC electric locomotive of the VL61 series № 012 and continues with the release of the modern series of electric locomotives 2 (3, 4) ES5K and EP1v/i. The use of recuperation allows you to achieve significant energy savings, to ensure the safety of driving heavy trains on the track profile with long descents. In the regenerative braking mode, the EPS has rigid braking characteristics, ensuring maintenance of constant train speed, increasing the technical speed of the train and capacity of the railway section. This article presents the results of mathematical modeling of operation of an AC electric locomotive in the regenerative braking mode using a standard rectifier-inverter converter (RIC) and presence of ballast resistor blocks (BRB) in the power circuit, and using a promising RIC based on IGBT transistors, for which a method for implementing regenerative braking on AC electric locomotives without the use of BRB in the anchor circuit of traction electric motors is developed, with the help of which it is possible to increase the amount of electricity given to the contact network, as well as to expand the area of braking characteristics of the electric locomotive.
