Experiences of Indigenous peoples in Canada with primary health care services: a qualitative systematic review protocol
Authors: Barbo Geneveave , Alam Sharmin , Kiafar Anita
Published: June 2021

Objective:

The objectives of this review are to aggregate and synthesize experiences of Indigenous peoples in Canada when receiving primary health care services; differentiate experiences from services provided in urban versus rural or remote settings; and identify recommendations to enhance quality of primary health care provision.

Introduction:

Primary health care plays a crucial role in overall population health and health equity. In Canada, Indigenous peoples continue to face disproportionate health disparities. Survey and qualitative studies on the experiences of Indigenous populations with primary health care services reveal alarming findings of inadequate health care access, racial discrimination, negligence, and cultural insensitivities. However, these studies do not entirely assess the primary care and essential public health functions component. This protocol will be the first qualitative systematic review to thoroughly synthesize Indigenous peoples’ overall primary health care experiences across all Canada, in both rural and urban settings.

Inclusion criteria:

The population of interest is self-identified Indigenous peoples, who have first- and/or second-hand experience receiving primary health care services in Canada, regardless of their age, gender, or medical condition. Our focus is on patients’ experiences in contexts where primary health care services are delivered in Canada. Only qualitative studies in English or French will be considered.

Methods:

MEDLINE, CINAHL, PubMed, PsycINFO, Embase, and Web of Science will be used as information sources in addition to Google Scholar, Bielefeld Academic Search Engine, ProQuest Dissertations and Theses, and other relevant organization websites. Two independent reviewers will perform the screening, critical appraisal, and data extraction of selected articles. Results will then be synthesized using the meta-aggregation approach.

Communication skills in dietetic practice: a scoping review protocol
Authors: Knight Annemarie , Palermo Claire , Reedy Gabriel , Whelan Kevin
Published: June 2021

Objective:

This scoping review aims to examine and map the evidence regarding communication skills in dietetic practice and the education strategies used to develop them. Specifically, the review will address usage in practice, perceptions, and experiences, as well as the teaching and assessment of communication skills in student dietitians and dietitians.

Introduction:

Communication skills are a key element of practice for dietitians. Dietetic practice is evolving, and there is a need to explore the breadth of literature on communication skills for contemporary practice and how these skills are taught.

Inclusion criteria:

This scoping review will consider empirical research on dietitians’ or nutritionists’ communication skills. This will include skills used in dietitian–patient communication, in communication interactions in different employment contexts, and diverse forms of communication (verbal, written, technological). We will consider the views of student dietitians, dietitians, and patients, as well as evidence regarding how communication skills are taught and assessed in dietetics. Sources may include experimental, quasi-experimental, observational, and qualitative studies.

Methods:

The following electronic databases will be searched: MEDLINE, Embase, CINAHL, ERIC, and PsycINFO. There will be no date limits. Reference lists of eligible studies will be back-searched. Google Scholar will be used for forward citation tracking. Conference proceedings from the previous five years will be searched for eight conferences of the professional associations of dietetics and health care education. ProQuest Dissertations and Theses, and WorldCat Dissertations and Theses will be searched for unpublished literature. The findings will be summarized in tabular format and a narrative synthesis.
Weak Hip Strength Increases Dynamic Knee Valgus in Single-Leg Tasks of Collegiate Female Athletes
Authors: Crowell Kyndell R. , Nokes Ryan D. , Cosby Nicole L.
Published: June 2021

Clinical Scenario: Dynamic knee valgus (DKV) is a mechanical alteration in the knee that leads to increased risk of injury. Weakness of hip musculature in hip abduction (HABD), extension (HEXT), and external rotation (HER) may contribute to increased DKV in single-leg landing tasks. Focused Clinical Question: Is decreased hip strength associated with an increase in DKV during a single-leg landing task in collegiate female athletes? Summary of Key Findings: Three studies were included: One randomized control trial (RCT), one cohort study, and one case-control. All three studies found that decreases in HABD and HER strength contributed to increased DKV during single-leg landing tasks. One study also found that the hip extensors contribute to controlling hip adduction, a common factor in many mechanisms of injuries. These three studies recommended strengthening HABD, HEXT, and HER to decrease DKV and reduce the risk of injury at the knee. Clinical Bottom Line: Weak HABD, HEXT, and HER contribute to increased DKV in college female athletes, but strengthening HABD, HEXT, and HER can lead to decreases in DKV and, overall, reduce the risk of injury at the knee. Strength of Recommendation: These articles were graded with a level of evidence of III or higher, giving a grade of B strength of recommendation that weak HABD, HEXT, and HER are associated with increased DKV in collegiate female athletes.

Age and tectonic setting of the Quinebaug-Marlboro belt and implications for the history of Ganderian crustal fragments in southeastern New England, USA
Authors: Walsh Gregory J. , Aleinikoff John N. , Ayuso Robert A. , Wintsch Robert P.
Published: June 2021

Crustal fragments underlain by high-grade rocks represent a challenge to plate reconstructions, and integrated mapping, geochronology, and geochemistry enable the unravelling of the temporal and spatial history of exotic crustal blocks. The Quinebaug-Marlboro belt (QMB) is an enigmatic fragment on the trailing edge of the peri-Gondwanan Ganderian margin of southeastern New England. SHRIMP U-Pb geochronology and geochemistry indicate the presence of Ediacaran to Cambrian metamorphosed volcanic and intrusive rocks dated for the first time between ca. 540–500 Ma. The entire belt may preserve a cryptic, internal stratigraphy that is truncated by subsequent faulting. Detrital zircons from metapelite in the overlying Nashoba and Tatnic Hill Formations indicate deposition between ca. 485–435 Ma, with provenance from the underlying QMB or Ganderian crust. The Preston Gabbro (418 ± 3 Ma) provides a minimum age for the QMB. Mafic rocks are tholeiitic with trace elements that resemble arc and E-MORB sources, and samples with negative Nb-Ta anomalies are similar to arc-like rocks, but others show no negative Nb-Ta anomaly and are similar to rocks from E-MORB to OIB or backarc settings. Geochemistry points to a mixture of sources that include both mantle and continental crust. Metamorphic zircon, monazite, and titanite ages range from 400 to 305 Ma and intrusion of granitoids and migmatization occurred between 410 and 325 Ma. Age and chemistry support correlations with the Ellsworth terrane in Maine and the Penobscot arc and backarc system in Maritime Canada. The arc-rifting zone where the Mariana arc and the Mariana backarc basin converge is a possible modern analog.

Introduction

We aimed to investigate the individual and combined effects of age-specific and sex-specific pulse pressure (PP) and brachial-ankle pulse wave velocity (baPWV) on the incidence of new-onset diabetes mellitus.

Research design and methods

Participants in the Kailuan study cohort who were ≥20 years old, participated in follow-up assessments and underwent baPWV measurements in 2010–2011, 2012–2013, and 2014–2015 were studied. The participants were allocated to four groups according to their PP and baPWV status, each categorized as high or normal, according to age-specific and sex-specific median values. Cox proportional hazards models were used to explore the individual and combined effects of PP and baPWV on the incidence of diabetes mellitus.

Results

There were 18 619 participants who were followed for 4.27±1.91 years. A total of 877 new cases of diabetes were identified, and the incidence density was 11.03/1000 per year. Using the normal PP and normal baPWV group as the reference group, the multivariable-adjusted HRs and 95% CIs for diabetes mellitus in the high PP and high baPWV groups were 1.08 (0.93 to 1.25) and 1.64 (1.41 to 1.90), respectively. Compared with the normal PP/baPWV group, the HR and 95% CI for diabetes in the normal PP/high baPWV, the high PP/normal baPWV, and high PP/baPWV groups were 1.66 (1.35 to 2.05), 1.09 (0.86 to 1.37), and 1.74 (1.43 to 2.13), respectively.

Conclusions

High baPWV was independently associated with a higher risk of diabetes mellitus, and individuals with both high baPWV and high PP were at a still higher risk of diabetes mellitus.

Published: June 2021

Objective

To compare the cost implications of botulinum neurotoxin (BNT) injection to surgery in infantile esotropia (IE) in a public/government funded hospital.

Methods and analysis

A simple costing comparison was undertaken for a randomised clinical trial in IE. Patients were randomised to receive either BNT or standard surgery. The participants in the BNT arm were further subdivided into subgroups based on their age in months and degree of esotropia in prism dioptres (PD) at presentation: G1 ≤60 PD/24 months, G2 ≤24 months/>60 PD, G3 >24 months/≤60 PD, G4 >24 months/>60 PD. The costs were calculated for each arm from primary treatment to eventual satisfactory outcome defined as orthophoria or microtropia (≤10 PD). A bottom-up costing analysis was done for single and multiple procedures for each arm. Comprehensive variable costs as well as fixed costs were calculated at each point of intervention and expressed in local currency ZAR (US$1=ZAR15.00). Costing was analysed for surgery and BNT subgroups (based on clinical success)

Results

There were 101 patients enrolled in the trial. 54 in the BNT arm and 47 in the surgery arm. Cost for single surgery and single BNT was ZAR 7743.04 and 1713.14, respectively. A favourable clinical outcome was achieved in 72% of surgery arm and 37% of BNT arm. The mean cost for eventual favourable outcome in BNT arm was ZAR9158.08 and in surgery arm ZAR9124.27 (p=0.26). Mean cost in G1 was ZAR6328.45, in G2 ZAR7197.45, in G3 ZAR11891.93 and G4 ZAR12882.44 (p=0.018).

Conclusion

BNT has a cost–benefit in IE and is a viable option in the primary treatment of IE in resource constrained regions. Clinical outcomes and economic benefit in smaller angle of esotropia and younger patients are comparable to surgery.

Authors: Ferreira David , Graffen Simon , Watkins Brendan , Peters Bridie , Lim Geok Jim , Kamalanathan Harish , Leitch James , Sverdlov Aaron , Collins Nicholas , Boyle Andrew , Davies Allan
Published: June 2021

Objective

To assess the changes in cardiac hospitalisations, acute coronary syndromes (ACS) and out-of-hospital cardiac arrest (OOHCA) during COVID-19 isolation compared with prior time periods in an area of low COVID-19 disease incidence.

Methods

Review of all cardiology admissions, non-ST segment elevation myocardial infarction (NSTEMI), ST-segment elevation myocardial infarction (STEMI) requiring urgent catheter laboratory activation and OOHCA. The 10-week period of government-imposed social isolation (23 March–31 May 2020) was compared with the same period in 2018, 2019 and a 10-week period prior to social isolation (6 January–15 March 2020). Incidence rate ratios were calculated. Symptom to balloon time was also compared for those requiring catheterisation laboratory activation for STEMI.

Results

The incidence of COVID-19 in the health district was 0.14 per 100 000 per day during the isolation period. There was a significant reduction in cardiology hospitalisations, NSTEMI and STEMI presentations without changes in OOHCA or symptom to balloon time for STEMI.

Conclusions

We observed a significant decline in cardiology presentations during social isolation without widespread COVID-19 disease. This provides further evidence for the important influence of social and behavioural factors on coronary event rates.
The role of shear deformation in pure tungsten: Mechanical properties and micro-mechanism
Authors: Li Ping , Shu Juan-Juan , Wang Lu-Sheng , Meng Miao , Xue Ke-Min
Published: June 2021

The effects of shear deformation at 1173 K on the mechanical properties and deformation mechanism of pure tungsten are investigated by molecular dynamics (MD). The results show that the shear deformation of pure tungsten is dominated by dislocation multiplication and slip band deformation. The shear angle has a significant effect on the mechanical properties of pure tungsten. The yield strength is 4.21 Gpa at a shear angle of 11[Formula: see text], and it increases significantly to 11.84 Gpa while the shear angle increasing to 27[Formula: see text]. In the plastic deformation stage, the stress–strain curve shows obvious oscillation due to the interaction of dislocations in the single-crystal tungsten and the effect of strain strengthening. In addition, the evolution of dislocation and twining in the compression system against shear angle indicates the variation of deformation behavior. When the shear angle is 11[Formula: see text], the lengths of dislocation 1/2[Formula: see text] and [Formula: see text] increase to a peak rapidly, which illustrates dislocation strengthening. However, when the shear angle is more than 11[Formula: see text], the decrease of dislocation length and the appearance of twins along [Formula: see text] direction demonstrate the twining accompanied with dislocation tangling, resulting in the additional increase of strength.

Published: June 2021

In this paper, we have introduced copure-direct-injective modules. A right [Formula: see text]-module [Formula: see text] is said to be copure-direct-injective if every copure submodule of [Formula: see text] isomorphic to a direct summand of [Formula: see text] is itself a direct summand. We have studied properties of copure-direct-injective modules. We characterized rings over which every (cofinitely generated, free, projective) module is copure-direct-injective. We have examined for which rings or under what conditions copure-direct-injective modules are direct-injective, quasi-injective, copure-injective, injective. Also we have compared copure-direct-injective modules with pure-direct-injective modules.

We study some properties of these polynomials and we prove that the polynomials used by Garcia, Stichtenoth and Thomas in their work on good recursive tame towers are [Formula: see text]-minimal value set polynomials for [Formula: see text], whose [Formula: see text]-value sets can be explicitly computed in terms of the monomial [Formula: see text].
GloBiMapsAI: An AI-Enhanced Probabilistic Data Structure for Global Raster Datasets
Authors: Werner Martin
Published: June 2021

In the last decade, more and more spatial data has been acquired on a global scale due to satellite missions, social media, and coordinated governmental activities. This observational data suffers from huge storage footprints and makes global analysis challenging. Therefore, many information products have been designed in which observations are turned into global maps showing features such as land cover or land use, often with only a few discrete values and sparse spatial coverage like only within cities. Traditional coding of such data as a raster image becomes challenging due to the sizes of the datasets and spatially non-local access patterns, for example, when labeling social media streams. This article proposes GloBiMap, a randomized data structure, based on Bloom filters, for modeling low-cardinality sparse raster images of excessive sizes in a configurable amount of memory with pure random access operations avoiding costly intermediate decompression. In addition, the data structure is designed to correct the inevitable errors of the randomized layer in order to have a fully exact representation. We show the feasibility of the approach on several real-world datasets including the Global Urban Footprint in which each pixel denotes whether a particular location contains a building at a resolution of roughly 10m globally as well as on a global Twitter sample of more than 220 million precisely geolocated tweets. In addition, we propose the integration of a denoiser engine based on artificial intelligence in order to reduce the amount of error correction information for extremely compressive GloBiMaps.

Published: June 2021

Multidimensional sleep trait, which is related to circadian rhythms closely, affects some cancers predominantly, while the relationship between sleep and lung cancer is rarely illustrated. We aimed to investigate whether sleep is causally associated with risk of lung cancer, through a two-sample Mendelian randomization study. The main analysis used publicly available GWAS summary data from two large consortia (UK Biobank and International Lung Cancer Consortium). Two-sample Mendelian randomization (MR) analysis was used to examine whether chronotype, getting up in the morning, sleep duration, nap during the day, or sleeplessness was causally associated with the risk of lung cancer. Additionally, multivariate MR analysis was also conducted to estimate the direct effects between sleep traits and lung cancer risks independent of smoking status including pack years of smoking or current tobacco smoking. There was no evidence of causal association between chronotype, getting up in the morning, or nap during the day and lung cancer. Sleeplessness was associated with higher risk of lung adenocarcinoma (odds ratio 5.75, 95% confidence intervals 2.12-15.65), while sleep duration played a protective role in lung cancer (0.46, 0.26-0.83). In multivariate MR analysis, sleeplessness and sleep duration remained to have similar results. In conclusion, we found robust evidence for effect of sleeplessness on lung adenocarcinoma risk and inconsistent evidence for a protective effect of sleep duration on lung cancer risk.
A New Ridge-Type Estimator for the Gamma Regression Model

Published: June 2021

The known linear regression model (LRM) is used mostly for modelling the QSAR relationship between the response variable (biological activity) and one or more physiochemical or structural properties which serve as the explanatory variables mainly when the distribution of the response variable is normal. The gamma regression model is employed often for a skewed dependent variable. The parameters in both models are estimated using the maximum likelihood estimator (MLE). However, the MLE becomes unstable in the presence of multicollinearity for both models. In this study, we propose a new estimator and suggest some biasing parameters to estimate the regression parameter for the gamma regression model when there is multicollinearity. A simulation study and a real-life application were performed for evaluating the estimators' performance via the mean squared error criterion. The results from simulation and the real-life application revealed that the proposed gamma estimator produced lower MSE values than other considered estimators.

Authors: Assefa Abebe , Girmay Getawey , Alemayehu Tesfaye , Lakew Alemu
Published: June 2021

Barley (Hordeum vulgare L.) is an annual cereal crop that belongs to the grass family Poaceae of the tribe Triticeae. Due to the establishment and production capacity of malt and beer factories in Ethiopia, malt barley production demand increased from time to time. Eight released malt barley varieties were evaluated in four environments in Wag-himra and Lasta districts in the main production season for two years (2016 and 2017). The objective of the trial was to identify a high yielder and standard-quality malting barley variety for production. The trial was conducted using a randomized complete block design with three replications on a plot size of 1.2 m width with that of 2.5 m length. The results revealed that there was a highly significant difference in grain yield and quality traits (

p

). The kernel protein and starch content of the varieties ranged from 9.85 to 11 and 63–65%. The thousand kernel weight of the varieties was in the range of 32.5 to 46.4 g. EH1847 (3340 kg ha−1), IBON174/03 (3351 kg ha−1), and Bahati (3220 kg ha−1) were the first three best performing high yielder and best varieties that fulfilled quality parameter requirements set by the National Standard Authority for malting barley. Therefore, these varieties are recommended for production in the Wag-himra and Lasta agroecologies for their high yield, kernel size, and kernel protein content. Further study is required on agronomic practices and brewing quality attributes in malt barley.

Published: June 2021

Regulatory T (Treg) cells are a subtype of CD4+ T cells that play a significant role in the protection from autoimmunity and the maintenance of immune tolerance via immune regulation. Epigenetic modifications of Treg cells (i.e., cytosine methylation at the promoter region of the transcription factor, Forkhead Box P3) have been found to be closely associated with allergic diseases, including allergic rhinitis, asthma, and food allergies. In this study, we highlighted the recent evidence on the contribution of epigenetic modifications in Treg cells to the pathogenesis of allergic diseases. Moreover, we also discussed directions for future clinical treatment approaches, with a particular emphasis on Treg cell-targeted therapies for allergic disorders.

Published: June 2021

Computation offloading has been widely recognized as an effective way to promote the capabilities of resource‐constrained mobile devices. Recent years have seen a renewal of the importance of this technology in the emerging field of mobile robots, supporting resource‐intensive robot applications. However, cooperating to solve complex tasks in the physical world, which is a significant feature of a robot swarm compared to traditional mobile computing devices, has not received in‐depth attention in research concerned with traditional computation offloading. In this study, we propose an approach named cooperation offloading, which offloads the intensive communication among robots as well as the computation for compute‐intensive and data‐intensive tasks. We analyze the performance gain of cooperation offloading by formalizing multirobot cooperative models; in addition, we study offloading decisions. Based on this approach, we design a cloud robotic framework named Cloudroid Swarm and develop several QoS‐aware mechanisms to provide a general solution to cooperation offloading with QoS assurance in multirobot cooperative scenes. We implement Cloudroid Swarm to transparently migrate multirobot applications to cloud servers without any code modification. We evaluate our framework using three different multirobot cooperative applications. Our results show that Cloudroid Swarm can be applied to various robotic applications and real‐world environments and bring significant benefits in terms of both network optimization and task performance. Besides, our framework has good scalability and can do support as many as 256 robot entities simultaneously.

Published: June 2021

With the rapid development of the Internet of Things and cloud computing technologies, the Internet of Things technology based on comprehensive perception and interconnection and cloud computing based on virtualization, dynamic resources, and parallel computing have become the driving force for the innovation and development of informatization and intelligence. The cloud‐based Internet of Things mobile medical is an ecosystem of health information and medical information, with the medical Internet of Things at its core and highly mobile and highly shared information. Therefore, in the context of in‐depth research on mobile medical care, research on mobile postoperative thyroid monitoring and management systems based on the Internet of Things and cloud computing is a practical tool for promoting the development of mobile medical systems. Monitoring and Management. In this experiment, 48 cases of patients undergoing thyroid surgery were selected from a hospital. The experimental group was informed by the experiment that they need to be equipped with sensors. The control panel and GPS positioning module are used to obtain the exact position of the patient at the first time. The loading of the sensor is agreed by the patient and the patient’s family. Afterward, the control group will not be processed. It will conduct functional tests and software performance tests on the mobile medical monitoring and management system and analyze the satisfaction of medical staff with the mobile medical monitoring and management system. Experiments have proved that the cloud computing medical monitoring and management system is used to obtain the exact location of the patient in the first time, and the response time needs to be shorter. The response time of the system increases with the increase of the number of sensors (P < 0.05), which shows that the mobile medical monitoring and management system is essential for medical care and medical care. Obtaining the exact position of the patient for the first time is of great importance for the successful rescue of the patient.

Published: June 2021

Considering the uncertainty of the flight dynamics model of the tilt-rotor aircraft in different flight modes, anL1adaptive controller for full flight modes control system of tilt-rotor aircraft is designed. Taking advantage of the separation of robustness and adaptive design of theL1adaptive controller, adaptive gain, and low-pass filter are designed to achieve the desired control performance and meet the requirements of flight quality. The simulations of XV-15 tilt-rotor aircraft in helicopter mode and airplane mode are carried out. Then, the simulation of conversion mode is further carried out. The results show that the tilt-rotor aircraft can track the reference signal well under theL1control system. In addition, the changes of states as well as controls in conversion mode flight are quite smooth which is very meaningful for engineering application.

Published: June 2021

Steam-assisted gravity drainage (SAGD) has been used to develop the “super heavy” oil reservoirs in Canada. The viscosity can reach more than 30,000 cp at 50°C. Moreover, owing to their continental deposit origin, the reservoirs have a low porosity and permeability. Because of these challenges, the conventional steam circulation start-up process takes 6 to 12 months before the well pair can be switched to production. Solvent has been used to start-up SAGD with success. But now, low price of oil and high cost of solvent make solvent-assisted start-up process limited. This paper applies experimental schemes, such as viscosity reduction rate evaluation, core flooding, and 3D physical simulation, tests solvent performance, optimizes process parameters, and designs process solutions. Apply numerical simulation to test solvent-assisted SAGD start-up effect and calculate the cost. This paper researches a unique low-cost solvent compare with xylene. The basic properties and core flood experiment show that the two solvents are similar with viscosity reduction rate, asphalt dissolution rate, and injection pressure, and the price of solvent is 18% lower. The 3D model experiment shows that the average start-up time is reduced by 15%, and steam injection volume is reduced by 21.4%. The numerical simulation results show that without solvent, it will take 180 d for start-up process, and with solvent, the time has reduced by 50% and takes 90 days. Cost calculation results show that the cost will reduce 18% by solvent compared to xylene. Moreover, the production rate has been improved in production stage. This paper applies a 3D physical model to simulate the solvent-assisted SAGD start-up process. Research conclusions show the start-up mechanism of solvent and the process of temperature change of steam chamber.

Authors: Zain Mostafa , Khairi Ahmed , Abouheba Mohamed
Published: June 2021

Congenital web of the gastrointestinal tract is a rare anomaly which may present at any site of the gastrointestinal tract. In cases with an intact membrane, the presenting symptoms may take the form of complete intestinal obstruction while in other cases with a fenestrated membrane, it may present with partial intestinal obstruction such as failure to thrive, volume depletion, or poor body-weight gain, representing a chronic condition. It is very rare for a jejunal web to present with retention of accidently ingested foreign body. In this report, we document a case of 14-month boy with retention of accidently ingested button battery who was found to have a jejunal web on surgical exploration. This case report stresses on the importance of prevention of ingestion of inanimate foreign bodies especially in young infants and that the absence of symptoms does not preclude presence of foreign body in children. Also, surgeons should be prepared to deal with other unsuspected findings intraoperatively. After a review of the literature, jejunal web should be considered in the differential diagnosis of chronic partial intestinal obstruction even in adults.
ASSESSMENT OF TOTAL CARDIOVASCULAR RISK IN PATIENTS WITH ARTERIAL HYPERTENSION AND COMORBID CHRONIC OBSTRUCTIVE PULMONARY DISEASE
Authors: Vysochyna I. L. , Burtniak T. Z.
Published: June 2021

The aim – to determine the total cardiovascular risk (CVR) in patients with AH and comorbid COPD.
Material and Methods. The study included 120 patients with hypertension stage II, grade 2, 3 and 3 in combination with COPD grade II-III and clinical groups A, B, C, D. The study methods included general clinical examination (collection of complaints, medical history, clinical examination, anthropometric parameters), laboratory (blood lipids, blood glucose, blood creatinine, calculated glomerular filtration rate according to CKD-EPI) and instrumental methods (electrocardiography, Doppler echocardiography, ambulatory blood pressure monitoring, spirometry).
Results. The SCORE scale revealed that in one case there were no individuals with low CVR among patients with AH and comorbid COPD. In the patient group, 57.5 % were found to have a moderate CVR, 36.7 % had a high CVR, and a very high risk was established in 5.8 % of cases. Pulse pressure, aortic stiffness index, ECG and EchoCG signs of left ventricular hypertrophy, and glomerular filtration rate were analyzed to detect asymptomatic hypertensive target organ damage. The patients were stratified by determining the total CVR. It was found that there were no patients with a moderate degree of CVR in group 1, the number of patients with a high degree of CVR increased to 85.0 %, and a very high degree of CVR increased to 15.0 %.
Conclusion. The cardiovascular risk in patients with AH and comorbid COPD depends not only on the degree of AH, the profile of cardiac risk factors and target organ damage, but also on the degree and clinical group of COPD.

ОСОБЛИВОСТІ РОЗВИТКУ МОВЛЕННЯ У ДІТЕЙ З ІНТЕЛЕКТУАЛЬНИМИ ПОРУШЕННЯМИ
Authors: Бєлова О. Б.
Published: June 2021

У науковій роботі здійснено теоретичний аналіз особливостей розвитку мовлення у дітей з інтелектуальними порушеннями. Мета дослідження – теоретичне обґрунтування розвитку мовлення у дітей з інтелектуальними порушеннями. Завдання дослідження – висвітлити теоретичний аналіз наукової літератури, як класичних, так і сучасних досліджень, щодо проблеми вивчення; розглянути причини інтелектуальних порушень; висвітлити ступені інтелектуальних порушень за міжнародною медичною класифікацією (МКХ-10, DSM-IV-TR); проаналізувати специфіку розвитку мовлення у різних категорій дітей з інтелектуальними порушеннями. У результаті науково-теоретичного дослідження було визначено, що, залежно від своєрідності порушень та ступеня уражень кори головного мозку, мовленнєвий розвиток у дітей з інтелектуальними порушеннями має свої особливості. Визначено, що причинами інтелектуального недорозвинення є органічний вплив несприятливих чинників у пренатальному, натальному та постнатальному періодах розвитку дитини. Аналіз наукового дослідження вказує, що діти з інтелектуальними порушеннями мають усі форми порушень мовлення. У структурі системного мовленнєвого недорозвинен­ня переважає семантичний дефект. Причини порушень мовлення визначаються ступеневою неврологічною симптоматикою. Медичний вплив, навчально-корекційна робота можуть наблизити деякі категорії дітей до типового мовленнєвого розвитку. Визначені аспекти дитячої логопатології вказують на специфіку психофізичних порушень. Основою мовленнєвої сформованості у дітей є розвиток сприймання звуків мови, правильна звуковимова, розуміння смислу слів, збагачений словниковий запас, морфологічно-синтаксична правильність мовлення, здійснення розповіді, переказу, діалогу, використання мовлення в соціальних ситуаціях.

Published: June 2021

Актуальність дослідження зумовлена суттєвими змінами у функціонуванні закладів вищої освіти (ЗВО) щодо підготовки нової генерації фахівців. Можливість концептуально осмислити об’єктивні зв’язки між елементами, компонентами, етапами процесу підготовки майбутніх викладачів медичного ЗВО дозволяє процес моделювання. Мета статті – на основі наукових ідей теоретично обґрунтувати наявні підходи до проблеми моделювання професійної діяльності майбутніх фахівців медичних ЗВО. Під час проведення дослідження було застосовано такі методи науково-педагогічного дослідження: системний  аналіз, синтез та узагальнення науково-педагогічної літератури, моделювання. Результати дослідження: 1) моделювання дозволяє прогнозувати розвиток педагогічного процесу, орієнтує викладачів на досягнення кінцевих результатів навчання, забезпечує засвоєння й ефективне використання нових технологій, розвиває системне бачення розв’язання проблем, служить дійовим фактором поліпшення якості роботи ЗВО; 2) завдання моделювання професійної підготовки викладача медичного ЗВО полягає у встановленні відповідності між вимогами до підготовки викладача і фактичним обсягом професійних знань та вмінь, рівнем його компетентності, зокрема передбачає опис еталонних вимог до нього як фахівця: функцій, які він має виконувати на робочому місці; задач, які повинен вміти розв’язувати; професійних компетентностей, які дозволяють фахівцю виконувати посадові обов’язки високопрофесійно, творчо, інноваційно; 3) моделювання професійної підготовки викладача передбачає побудову моделі, що являє собою сукупність цільового, мотиваційного, теоретико-методологічного, змістовно-технологічного, рефлексивно-аналітичного, результативно-оцінювального компонентів, які в сукупності створюють фундамент для формування компетентностей, що визначають готовність майбутніх фахівців медичної сфери до професійної діяльності у медичному ЗВО.

У статті розглядаються актуальні питання комунікаційної культури майбутніх лікарів. Автори аналізують різні підходи до визначення категорії дітей з особливими потребами, які потребують уніфікації. Виокремлено коло завдань, пов’язаних із педагогічною підготовкою майбутніх лікарів до надання медичних послуг дітям з особливими потребами: удосконалення методики викладання навчальних дисциплін етичного спрямування, доповнення змісту навчально-виховної роботи в закладах вищої медичної освіти інформаційними матеріалами про специфіку комунікації фахівців сфери охорони здоров’я з дітьми з особливими потребами, формування професійної готовності майбутніх лікарів до просвітницької роботи з батьками «особливих дітей». Визначено базові цінності в контексті культури спілкування майбутніх лікарів з дітьми з особливими потребами, такі, як: пацієнтоцентричність, особистісний підхід, повага людської гідності осіб з особливими потребами, реалізація їх прав та інтере­сів, створення усіх відповідних умов для ефективної діагностики, лікування й консультації дітей з особливими потребами, співпраця з фахівцями інших сфер та громадськістю щодо всебічної підтримки дітей даної категорії і їх родин. Виокремлено психологічні, педагогічні та філологічні аспекти об’єктивної самооцінки майбутніх лікарів як необхідної умови формування їх комунікаційної культури. Підкреслено важливість емпатії, врахування специфіки майбутньої професійної діяльності, особ­ли­вості спілкування з дітьми-сиротами, дітьми з інвалідністю. Доведено ефективність нових методів організації навчального процесу, таких, як: взаємне рецензування, самооцінка, експертна оцінка, підготовка опорних схем (mind map). Визначено перспек­тивні напрями дослідження, що пов’язані з упровадженням інклюзивних цінностей у навчально-виховний процес вищої медичної школи.
Um poeta da cena russa: Meyerhold e o teatro russo de vanguarda
Authors: Cavaliere Arlete O.
Published: June 2021

Até 1917, as tendências opostas do teatro russo estiveram representadas por dois homens: Konstantin Stanislávski, reconhecido universalmente como chefe da tendência realista e psicológica, e Vsévolod Meyerhold, figura polêmica, muito discutido e desprezado pela maior parte dos críticos, mas que impressionava o público e os profissionais de teatro como um grande inovador que se preocupava, sobretudo, em criar um “teatro do espetá- culo”, onde a ênfase estava nos recursos externos, visuais e auditivos.
O bilinguismo chinês/português será extinto?
Authors: Shyu David Jye Yuan
Published: June 2021

Saber até quando a cultura chinesa pode ser preservada, dentro de uma outra cultura, não é uma resposta fácil de ser respondida. A princípio, tudo indica que a língua chinesa – principal pilar da cultura – será a primeira a desmoronar. Ela vai sendo lentamente substituída pela língua que é falada no ambiente, ficando restrita ao meio familiar. No entanto, este último reduto da língua chinesa vai, progressivamente, sendo “invadido”, à medida que os filhos de imigrantes começam a se integrar mais facilmente à sociedade brasileira, tendo como padrão a língua portuguesa . Caso não haja interferência dos outros fatores, a língua chinesa (com seus dialetos) dentro da colônia chinesa está fadada ao desaparecimento. Estes fatores podem ser, dadas as circunstâncias atuais, uma grande imigração de chineses ao Brasil, o que remediaria o desaparecimento, e o crescente poder econômico e político da China que estimularia não só os descendentes, como também encorajaria os estrangeiros a dominar a língua chinesa.

Desde o início, meu encontro com Haroldo de Campos pautou-se no interesse mútuo pelas questões próprias da poesia semítica e a ela relacionadas. Apresentei-me ao poeta em janeiro de 1990, no sobrado da Monte Alegre, com os rascunhos da minha tradução do penúltimo capítulo do Cântico dos Cânticos, feita a partir da versão árabe de 1909, por sua vez tradução bastante razoável de original grego.

walad: Feto ou Filho; A Restauração do Sentido Original de Gn 11:30
Authors: Chwarts Suzana
Published: June 2021

Esta pesquisa focaliza o termo walad na caracterização de Sara como estéril em Gn 11:30 - wa tehi śarai aqarah ein lah walad  duas orações traduzidas universalmente como e Sara é estéril, não tem filho(s). A segunda oração foi considerada uma redundância e a palavra walad , um erro por parte do escriba que copiou as Escrituras. No contexto de minha interpretação da narrativa patriarcal, walad é uma escolha deliberada e engenhosa por parte do redator. De forma alguma o termo está solto ou isolado no corpo da narrativa. Ao contrário; estabelece uma correspondência entre episódios, um campo de força temático 1 que delineia um ciclo de esterilidade intra-abraâmico, específico a Sara e Abraão, iniciado em Gn11:30 e concluído em Gn21:5, com o nascimento de Isaac. walad com o sentido de feto  minha proposta de tradução - funciona como fio condutor da narrativa, interligando-se fonetica e semanticamente ao verbo lehiwaled ( nascer ) em Gn 17 e 21. Dessa forma, confere contornos específicos à narrativa, que evolui da imposssibilidade reprodutiva dos protagonistas ao cumprimento da promessa divina a Abraão e Sara. Essa terminologia memorável encerra profundo valor teológico: ao assinalar a ausência de feto no útero de Sara e a impossibilidade de dois idosos gerarem, expõe a perspectiva humana em contraponto à natureza miraculosa dos desígnios divinos. A pesquisa considera, ainda, a possibilidade que ein lah walad seja uma inserção sacerdotal num trecho javista .
