The Possibility of blocking the femoral nerve under ultrasound control with the use of the electrical stimulator of the peripheral nerves with small doses of ropivacaine
Authors: Piacherski Valery G. , Marachkou A. V.
Published: February 2021

Goal. The aim of the study is to determine the possibility of using small volumes of ropivacaine for blockade of the femoral nerve performed with the use of an electrostimulator of peripheral nerves under ultrasound.
Materials and methods. 44 blockages of the femoral nerve were performed under ultrasound control with the use of electrical stimulation of the peripheral nerves. In the first group (22 patients), a blockade of the femoral nerve was performed with 10 ml of 0.75% ropivacaine; in the second group (22 patients), 0.75% ropivacaine was used in a volume of 5 ml. Evaluation of the development time of the sensory, motor blocks and the duration of analgesia was carried out from the time the local anesthetic solution was introduced into the fascial sheath of the femoral nerve.
Results. The time of development of the complete sensory block in the 1st and 2nd groups of patients was 21 (20; 24) minutes and 30 (24; 35) minutes (p 0.05). The time of development of the full motor block in the 1st group was 22 (16; 24) minutes; in the second group, 21 (17; 30) minutes (p 0.05). There was no difference in the duration of analgesia in the postoperative period between the groups: 7.75 (7; 8) h and 8 (7.5, 8) h. respectively (p 0.05).
Conclusion. It has been established that 5 ml of 0.75% solution of ropivacaine is sufficient for effective blockade of the femoral nerve. With a decrease in the effective amount and volume of local anesthetic, there is an increase in the time of development of complete blockade of the femoral nerve without reducing the period of postoperative analgesia.

Objective: To evaluate the effectiveness of interscalene brachial plexus block versus combined suprascapular and axillary nerves block for shoulder arthroscopy. Methods: In this prospective study 174 patients were operated on the shoulder joint by the arthroscopic method under combined anesthesia. In the 1st group (n=96), for the purpose of analgesia, patients got interscalene brachial plexus block; in the 2nd group (n=78), patients received suprascapular and axillary nerves block. Ultrasound visualization and neurostimulation were used in both groups. Recorded the time from the start of blockade to the start of the operation, as well as the duration of the sensory and motor blockade. The intensity of postoperative pain was assessed with a 10-point Numeric rating scale, the need for additional analgesia, the quality of night sleep, and patient comfort. Neurological complications were also recorded.

Results: There were no differences in the time from the admit patients to the operating room and before the start surgery. The analgesic effect in the early postoperative period in the 1st group was higher, but by the end of the first day there was no statistical difference between the groups in the intensity of the pain syndrome. Intake of non-narcotic and narcotic analgesics was higher in the 2nd group. Complications were noted only for the 1st group: diaphragm paresis in 6 (6.25%) patients, in 2 (2.08%) recurrent laryngeal nerve blockade. Satisfaction with postoperative analgesia was 100% in patients of the 2nd group. The choice of regional anesthesia for arthroscopic interventions on the shoulder did not affect the length of hospitalization.

Conclusion: Selective anesthesia of the suprascapular and axillary nerves during shoulder arthroscopic surgery is an alternative of interscalene brachial plexus block; it is not associated by respiratory and neurological complications; does not violate movements in the distal upper limb, reduces psychological discomfort and anxiety of patients.

Summary. The aim of the study was to compare hemodynamic changes when using ropivacaine and levobupivacaine in patients during spinal anesthesia. Materials and methods: The study included 48 patients who were randomized into two groups, depending on the anesthetic used: group P ropivacaine, group L levobupivacaine. Changes in mean arterial pressure and heart rate were evaluated. Results: patients in group L showed stable hemodynamic parameters. On the contrary, in the group P for 12 min, arterial hypotension was registered in 45.8% of the subjects, for 15 min it was detected in 37.5% of cases. At 18 min, a decrease in mean arterial pressure was observed in 41.6% of patients, while in 12.5% of cases it was necessary to connect vasopressor support for norepinephrine in a dosage of 0.070.15 g/kg/min. When analyzing the heart rate of less than 60 beats/min in group L was not identified. At the same time, in group P, sinus bradycardia was registered at all stages of control of the heart rate, and in some cases atropine correction was required. Conclusions: the course of anesthesia in the group using levobupivacaine was characterized by stable mean arterial pressure and heart rate. Patients in the ropivacaine group showed a decrease in mean arterial pressure of less than 70 mm Hg. in a controlled period of time from 12.5% to 48.5% for the purpose of correction of which, use of vasopressor support was required by 12.5%. Bradycardia in this group was registered in 12.5% -54.1% of cases, while atropine was used in 12.5%.
Comment on “Dynamic Tilt Correction Using Direct Rotational Motion Measurements” by Felix Bernauer, Joachim Wassermann, and Heiner Igel
Authors: Graizer Vladimir
Published: February 2021

This article identifies deficiencies in the article of Bernauer et al. (2020) in performing and describing shake table and numerical (synthetic) testing of newly designed seismic instruments for recording complex translational and rotational motion. In my opinion, this is a result from a deficiency in referencing previously published peer-reviewed papers in this area. I also disagree with Bernauer et al. (2020) interpretation of the origin of errors in a vertical sensor’s recording because the sensitivity of a vertical pendulum type sensor to small tilts is much lower than that of the horizontal. Complete differential equations of pendulum-type horizontal and vertical seismometers are presented and examples of previously performed numerical and shake table tests of seismic instruments are shown.

As the earliest institute in Turkey dedicated to locating, recording, and archiving earthquakes in the region, the Kandilli Observatory and Earthquake Research Institute (KOERI) has a long history in seismic observation, which dates back to the installation of its first seismometers soon after the devastating Istanbul earthquake of 10 July 1894. For over a century, since the deployment of its first seismometer, the KOERI seismic network has grown steadily in time. In this article, we present the KOERI seismic network facilities as a data center for the seismological community, providing data and services through the European Integrated Data Archive (EIDA) and the Rapid Raw Strong-Motion (RRSM) database, both integrated in the Observatories and Research Facilities for European Seismology (ORFEUS). The objective of this article is to provide an overview of the KOERI seismic services within ORFEUS and to introduce some of the procedures that allow to check the health of the seismic network and the quality of the data recorded at KOERI seismic stations, which are shared through EIDA and RRSM.

Strong ground motion records and free open access to strong-motion data repositories are fundamental inputs to seismology, engineering seismology, soil dynamics, and earthquake engineering science and practice. This article presents the current status and outlook of the Observatories and Research Facilities for European Seismology (ORFEUS) coordinated strong-motion seismology services, namely the rapid raw strong-motion (RRSM) and the engineering strong-motion (ESM) databases and associated web interfaces and webservices. We compare and discuss the role and use of these two systems using the Mw 6.5 Norcia (Central Italy) earthquake that occurred on 30 October 2016 as an example of a well-recorded earthquake that triggered major interest in the seismological and earthquake engineering communities. The RRSM is a fully automated system for rapid dissemination of earthquake shaking information, whereas the ESM provides quality-checked, manually processed waveforms and reviewed earthquake information. The RRSM uses only data from the European Integrated Waveform Data Archive, whereas the ESM also includes offline data from other sources, such as the ITalian ACcelerometric Archive (ITACA). Advanced software tools are also included in the ESM to allow users to process strong-motion data and to select ground-motion waveform sets for seismic structural analyses. The RRSM and ESM are complementary services designed for a variety of possible stakeholders, ranging from scientists to the educated general public. The RRSM and ESM are developed, organized, and reviewed by selected members of the seismological community in Europe, including strong-motion data providers and expert users. Global access and usage of the data is encouraged. The ESM is presently the reference database for harmonized seismic hazard and risk studies in Europe. ORFEUS strong-motion data are open, “Findable, Accessible, Interoperable, and Reusable,” and accompanied by licensing information. The users are encouraged to properly cite the data providers, using the digital object identifiers of the seismic networks.

The need for safe and effective treatment is becoming increasingly urgent due to the high COVID-19 mortality rates observed worldwide. The choice of drug products for COVID-19 treatment regimens is based on the efficacy and safety data, the mechanism of action, and potential interactions. N-acetylcysteine's (NAC) pharmacological activity and its potential to suppress the progression of COVID-19 make it a promising therapeutic agent for COVID-19.Aimof the study was to evaluate the efficacy of NAC in the complex treatment of moderate COVID-associated pneumonia.Methods. The study included adult patients (n= 46) with moderate COVID-associated (the 2nddegree on CT) pneumonia (age 57 (51; 71) years, body mass index - 30 (27.1; 32.3) kg/m2, duration of the disease before hospitalization - 7 (6; 8) days, body temperature at the admission - 37.5 (37.1; 37.8)°С). The patients were randomized into two study groups. The 1stgroup (n= 22) received standard COVID-19 treatment [1]. The 2ndgroup (n= 24) additionally received NAC 1,200 - 1,500 mg/day intravenously. Treatment with NAC was started together with the standard therapy.Results. Our study showed that the inclusion of NAC in the complex treatment of moderate COVID-associated pneumonia led to a statistically significant increase in blood oxygen saturation, oxygenation index, the difference in delta increase in oxygenation index, a quicker reduction in the volume of lung damage and the difference between the groups in delta reduction of this index. Also, the rate of reduction of C-reactive protein and reduction of the duration of hospitalization in the group of patients who received NAC was statistically significantly more profound than in the standard treatment group.Conclusion. The study confirmed the effectiveness of NAC as a part of the complex treatment of moderate COVID-associated pneumonia.

Achieving the control of bronchial asthma (BA) in real clinical practice remains an unresolved problem, despite the expansion of therapeutic options in this area. Guidelines about when and for whom should a particular treatment be used continue to develop. Increasing of inhaled corticosteroid dose (ICS) in combination with a long-acting β2-agonist (LABA) does not always lead to the desired result, although a combined LABA-ICS inhaler could improve the course of asthma and increase adherence. The addition of tiotropium bromide to LABA-ICS requires the use of two inhalers. The targeted biological therapy is associated with the complexity of phenotyping and is possible only in specialized medical centers. Mometasone furoate, indacaterol acetate, and glycopyrronium bromide in fixed doses were combined in Breezhaler® inhaler for asthma maintenance therapy once per day. This way of treatment helps to realize full potential of maintenance inhalation therapy of bronchial asthma and to simplify the achievement of control over the disease in routine clinical practice.

The combination of bronchial asthma (BA) and chronic rhinosinusitis with nasal polyps (CRSwNP) is currently considered a separate phenotype wit1 dysregulation of pro- and anti-inflammatory cytokines as one of t1e leading causes of inflammation.The aimof this study was to investigate the local and systemic inflammatory process in patients with BA associated with CRSwNP.Methods. The study enrolled 96 volunteers divided into 4 groups: the 1stwas healthy control (Normal); the 2ndhad allergic BA associated with CRSwNP; the 3rdhad nonallergic BA associated with CRSwNP; the 4thhad CRSwNP without BA. All participants of the study underwent clinical, laboratory, instrumental, and histological examinations. The expression ofil-1β, il-4, il-,5 il-6, il-13, il-37, il-17f, ifn-γ, tnf-αandtgf-βgenes was assessed in the peripheral blood mononuclear cells - PBMC and in the polyp tissue using RT-PCR. We also estimated the expression oftslp, il-25andil-33in the polyp tissue and expression of GATA3 and RORgt transcription factors in PBMC.Results. The pathogenesis of BA associated with CRSwNP is characterized by the dys-regulation of the local pro- and anti-inflammatory cytokines of the Th1-, Th2-, Th17- immune response. Moreover, the high expression ofil-37gene in patients with BA associated with CRSwNP, and especially in patients with not-allergic BA associated with CRSwNP, probably indicates the «inclusion» of the compensatory mechanism. In addition, BA associated with CRSwNP is characterized by severe course of both diseases. A nonallergic BA associated with CRSwNP is characterized by more pronounced eosinophilic inflammation, which is an unfavorable prognostic factor.Conclusion. Thus, a comparison of the levels of local and systemic cytokine expression in patients with BA associated with CRSwNP led to the conclusion that CRSwNP affects the local immunity more than systemic immunity. However, the latter is affected to some extent in the long-term as well.
Hypersensitivity pneumonitis
Authors: Avdeev S. N.
Published: February 2021

Hypersensitivity pneumonitis (HP) is an inflammatory disease of the lungs and airways that develops in response to repeated inhalation of a wide range of aerosol antigens. The clinical picture and course of HP are highly variable and depend on such factors as the nature of the antigen, the intensity and duration of exposure to the antigen, as well as on the characteristics of the patient's immune response. The annual incidence of HAP is 1.28 -1.94 cases per 100 000. Currently, the diagnosis of HP is usually based on the characteristic clinical picture, high-resolution computed tomography (HRCT) data, bronchoscopy, lung biopsy, and evidence on the antigen. HRCT plays a central role in the diagnosis of HP. The most common finding on HRCT in HP is ground-glass opacities, which can be associated with centrilobular nodules and air trapping. In some cases, the fibrotic HP signs are very similar to those of idiopathic pulmonary fibrosis (IPF), and most changes are found in the lower regions and subpleurally. Therapy for HP usually includes avoiding exposure to the antigen, considering corticosteroids (CS) and/or immunosuppressive therapy to suppress the active inflammatory/immune response, and treating comorbidities. Nintedanib therapy in patients with progressive fibrotic HP results in a slower decline of lung function compared to placebo.

Published: February 2021

Frontline healthcare workers (HCWs) are repeatedly exposed to SARS-CoV-2 and chance of exposure to it are invariably high than any other category of population. In this study, we investigated suspected cases of SARS-CoV-2 reinfection among eight HCWs involved in COVID-19 healthcare duty in Dibrugarh, Assam. Diagnosis of SARS-CoV-2 was done by Real Time RT-PCR or Rapid Antigen Detection Test at AMCH, Dibrugarh and ICMR-RMRC, Dibrugarh. Cases who tested positive for SARS-CoV-2 by RT-PCR or RAT for the second time and with symptoms suggestive of COVID-19 were included in this investigation as suspected cases of reinfection. SARS-CoV-2 IgG Ab titre and immune status ratio was estimated using a commercial SARS-CoV-2 Ig Ab detection ELISA kit. All eight cases were asymptomatic in first episode of infection with a C value above 30 and were non-reactive for SARS-CoV-2 IgG Ab. The second episode was symptomatic and marginally severe in some cases with C value less than 30 and with positive SARS-CoV-2 Ab titre. Most asymptomatic cases with C value above 30 failed to elicit immune response during the first episode. This may suggest that SARS-CoV-2 in low amount might be harbored transiently as bystander in droplet particles before being expelled from the nasal cavity which can be detected by the highly sensitive Real Time RT-PCR test. They may be below the infectious dose that is necessary to cause a clinical or a sub-clinical infection and fails to illicit an immune response. It is therefore very important to critically analyze the suspected cases of reinfection to be labelled as true reinfections. In conclusion, not all resurgence of symptoms with positive SARS-CoV-2 result for the second time after recovery are true reinfections and may be labelled as retest positives rather than reinfections. Further, routine surveillance of SARS-CoV-2 Ab testing for HCW is recommended to ascertain their immune status as they are the frontline workers of managing COVID-19 patients and are highly exposed to SARS-CoV-2 infection, and have a much higher risk of re-infection than the general public.

“Breast cancer is one of the foremost reasons for cancer death in the fewer developed countries of the world. This is partially because a change in lifestyles it’s affecting growth in occurrence and partially because of clinical advances to combat the disease are not reaching women existing in these regions. Adjuvant radiotherapy given subsequent operation for primary carcinoma of the breast has been revealed to reduce the occurrence of locoregional reappearance from 30% to 10.5% at 20 years and breast cancer deaths by 5.4% at 20 years.

40 patients by initial-stage breast cancer underwent calculated tomography. 2 diverse treatment strategies were created for each patient: the wedge-based (conventional) strategy and the FIF plan. Dosimetric parameters and monitor components were associated with paired sample t-test.

FIF technique gained significantly lower dose homogeneity index, lower maximum doses, and higher median doses in PTV (P<0.05). Similarly, the conformity index, and mean doses were higher in the FIF technique but the changes were not significant (P>0.05). In ipsilateral lungs, FIF significantly reduced the maximum and mean doses (P<0.05), and showed a tendency to reduce V20 (P>0.05). In patients with left-sided breast cancer, minimum and maximum doses and V40 of heart were significantly decreased in FIF plans (P<0.05). Doses to the contralateral lungs did not differ significantly.

These results along with significantly fewer monitor unit’s essential for therapy in FIF suggest that this technique may be more advantageous during breast irradiation.
Опыт проведения опроса резидентов центров постоянного пребывания мигрантов и беженцев в Республике Сербия по вопросу интеграции в новое окружение

Published: February 2021

Миграционные процессы существуют с начала мировой истории и являются частью механизма функционирования общества, что обуславливает необходимость, но также сложность исследования разнообразных процессов миграции, которые сегодня зачастую становятся причиной общественного кризиса. Социальное взаимодействие мигрантов с принимающим обществом является неотъемлемым элементом механизма управления миграцией, что определяет целесообразность нашего подхода к изучению данной проблемы. Социологический опрос, который мы провели во всех пяти постоянных центрах приема мигрантов и беженцев в Сербии, уникален тем, что респондентами являлись сами мигранты – это редкий случай в целом и первый в своем роде в стране. Исследование выявило возможность интеграции в принимающее сербское сообщество с позиции и с учетом интересов самих мигрантов. Автор предлагает новый тип интеграции в рамках не более одной семьи и рекомендует применять индивидуальный подход на основе принципа дисперсии по инициативе местного сообщества на локальном уровне. Дисперсная интеграция способствует предотвращению геттоизации мигрантов и улучшает их интеракцию с местным населением, что является предпосылкой для взаимодействия и социальной сплоченности.

The article presents data on combined anodic dissolution of aluminum alloy of Al–Li–Cu system with not high sensibility to intergranular corrosion, consisting in sequential dissolution in two different solutions, with different modes – the ratio of the specific amount of electricity. The obtained corrosion deteriorations were evaluated by optical and confocal microscopy, the dependences of mass loss, the depth of pitting and intergranular corrosion, as well as changes in the tensile strength of the specific amount of electricity for different modes were determined. As a result of the analysis of the obtained data, models for predicting the loss of tensile strength from the value of the specific amount of electricity (or mass loss) in atmospheric corrosion are proposed.

In many industries, such as mechanical engineering and aerospace, traditional alloys are being replaced by metal matrix composites (MCM). Compared to unreinforced alloys, MCM is characterized by increased strength and rigidity combined with low density. To calculate the resource of nodes for the safe and reliable operation of new equipment, it is necessary to have a set of calculated values of the MCM strength characteristics, including the characteristics of short-term and long-term strength, low-cycle (LCF) and high-cycle (HCF) fatigue. The work is devoted to the study of the characteristics of short-term and long-term strength, LCF and MCF fatigue of dispersion-strengthened MKM grade VKM22.

The influence of interstitial impurities in the Zr–Y target alloys (manufactured by two different techniques) on the quality of thermal barrier ceramic layers of heat resisting coating are studied in this work. The heat resisting ceramic coating manufactured in the UOKS-2 devices by magnetron medium-feculence plasma–chemical deposition on the surface of components that are used at the high temperatures (above 1150 °C). It was found that when the content of interstitial impurities in the target alloy is more than 0,1% (1000 ppm), the rate of the coating process decreases and has to be maintained by increasing the energy of argon ions. This leads to overheating of the target alloy and the surface of the parts (substrate) which impairs the adhesion of the deposited atoms.

The results of research on improving the fretting resistance of a titanium alloy made of orthorhombic titanium aluminide Ti2AlNb by forming a coating consisting of a barrier and an outer layer on the surface using an industrial vacuum-arc installation MAP-3 are presented. The dependences of the total wear and the coefficient of friction of samples made of Ti2AlNb alloy with and without coating in combination with a counterbody made of high-strength welded dispersed-hardening alloy during fretting damage tests at room (20 °C) and elevated (700 °C) temperatures are established. The kinetics of oxygen saturation of the surface of samples made of Ti2AlNb alloy with and without coating at the operating temperature of the alloy based on 200 h is shown. The phase and elemental compositions of the fretting-resistant coating after high-temperature exposure are investigated.

The paper presents the results of structural studies of metal-powder compositions (MPC) from the VSDP-3 alloy, as well as heat-resistant atmospheric-plasma powder coatings, developed at the FSUE «VIAM». As blanks for sputtering the MPC, standard charge blanks and exhausted resource cast tube cathodes for ion-plasma deposition were used. It was found that MPC obtained by sputtering cathodes and coatings deposited by sputtering these MPC are not inferior in properties to standard MPC and coatings. At the same time, the cost of such MPC and coatings can be 20–40% lower.
El juego del círculo hamoiij
Authors: Pasquereau Jérémy
Published: February 2021

Seri women play a traditional game called the circle game or hamoiij in cmiique iitom (the Seri language). In this game, women sit (on the ground or in chairs) around a circle traced in the sand upon which slices of cactus have been placed in groups of five. Each woman has a decorated wooden stick that she lays on the circle. Each woman in turn throws wooden strips, which, depending on how they fall, produce a specific number (like dice). Each woman then moves her stick around the circle, from one slice of cactus to the next, according to the number of points indicated by the wooden strips. The goal of the game is to ‘kill’ all the other sticks.
El diluvio (Tlaa:wetsilis). Una narración en náhuatl de la Huasteca Veracruzana
Authors: Martínez Martínez Andrés , Peralta Ramírez Valentín
Published: February 2021

This narrative is about the Great Flood and the creation of man and is told in the Nahuatl language of Tzocohuite in the municipality of Ixhuatlán de Madero, Veracruz. The myth begins with two actions carried out by the first inhabitants, a man and a woman, actions disapproved of by God, who punishes them. He sends his emissary, the rabbit, to tell the man to build an ark to save the animals and thus eliminates humans from the face of the Earth. After the Great Flood there are other events involving animals including the vulture, the dove and the hummingbird. Finally, man is punished with work and the rabbit retires to the moon, rewarded for having completed God’s orders. The Nahuatl text is presented together with a Spanish translation and interlinear morphological glosses.
Ni Chapoli: un cuento nahua de la Huasteca de Hidalgo, México
Authors: Miranda Juárez Vanessa , Vélez San Juan José
Published: February 2021

The cricket tale was told in the summer of 2016 by a seasoned storyteller: Mr. José Vélez San Juan. Mr. San Juan was born and raised in the Nahua community of the Huasteca region of Hidalgo, San Isidro Atlapexco. The central topic of the story is a conflict where insects and mammals play the central roles. The narrative focuses on how the cricket and the lion fight each other because the latter stepped on the former’s foot. In the end, the little cricket wins the fight even if he is much smaller than the lion. With the help of other powerful insects such as ants, bees and wasps, the cricket defeats the lion. One of the messages transmitted in this tale is how the cooperation and solidarity between many insects can result in a won battle. Such values are central to the cultural resistance that Nahua people have shown against western conquest. This tale is part of the daily negotiations of identity in the face of cultural differences.
Colombian Language Teachers Abroad: An Overview of Their Professional Experience
Authors: Torres-Casierra Liana Mercedes
Published: February 2021

This article presents the preliminary results of an enquiry on the work experience of Colombian language teachers who have entered the workforce in foreign countries. The study aims at unveiling aspects of the personal and professional experience of those graduates that might be relevant for pre-service teachers in local degree programs ahead of their potential move abroad in a growing international mobility context. The study includes data from surveys and personal interviews carried out with a group of 26 participants whose narratives of experience invite one to consider the variables that may either facilitate or hinder one’s teaching practice in a foreign workplace and the intercultural communication issues that language teachers may need to deal with. A reflection is brought forward on the needs that teacher training programs at university level in Colombia should address to broaden the scope of their graduates’ likely move abroad.
The Effectiveness of Using the Lexical Approach to Developing Ethiopian EFL Learners’ Vocabulary Competence
Authors: Sewbihon-Getie Addisu
Published: February 2021

This study investigated the effects of teaching vocabulary through the lexical instructional approach in EFL intermediate level students. Ninety-five (95) students participated in a non-equivalent pre-test-post-test quasi-experimental design study. The participants were given vocabulary competence pre-test in order to check their homogeneity in terms of their vocabulary knowledge. Then, following the similitude of the results they scored, the participants were randomly assigned as experimental group and the control group. For sixteen (16) weeks, the experimental group was taught by providing students with chunks and/or collocates of words through using collocation dictionaries, concordance programs, chunk-for-chunk translation activities, and corpus-based activities etc. Whereas, the control group was taught the new words in isolation with conventional teaching techniques; for example, translation at single word level, synonyms, antonyms, and definitions. After the instructional intervention, both groups participated in a vocabulary competence post-test. The Statistical Package for Social Science (SPSS) software version 22 was employed to analyse the results. In this regard, an independent Samples T-test was run and the findings of the study showed that the experimental group outperformed the control group in the post-test which implies that teaching vocabulary with a lexically-based instruction can improve EFL learners’ vocabulary competence or knowledge. Furthermore, the study results suggest that the lexical instructional approach should be the focus of future experimental research.
Pre-Service Language Teachers’ Knowledge and Practices of Intercultural Communicative Competence
Authors: Esteban-Núñez María Teresa
Published: February 2021

This paper reports a descriptive case study developed in an English language teaching program at a public university in Colombia. The purpose of this study was to disclose what knowledge a group of pre-service teachers had about intercultural communicative competence and how they considered their approach to this competence in the English classes they had planned during their final pedagogical practicum. The instruments used to collect data were documents, interviews, and a survey. The outcomes were meaningful for the participants as well as for the researcher since it was possible to identify that pre-service teachers understand this competence as a visible concept to be approached in the classes, mainly to refer to and learn about other cultures different from the Colombian and Boyacense ones. It was also identified that the intercultural communicative competence was considered, by these pre-service teachers, as the “dressing” to change the taste of the class.

Aim: Partial nephrectomy is the standard treatment for small renal tumors; however, it remains unclear which surgical approach from among robot-assisted partial nephrectomy (RAPN) and open partial nephrectomy (OPN) is superior. This study aimed to compare perioperative outcomes of RAPN and OPN performed at a single institution after adjusting for preoperative patient and tumor characteristics using propensity score matching (PSM). Methods: In this retrospective cohort study, patients who underwent RAPN or OPN for a renal mass of cT1-2 N0 M0 between 2005 and 2020 at our institution were recruited. The study outcomes were perioperative outcomes, complications, and pathological and functional outcomes. PSM was used to account for baseline covariates. Results: Overall, 131 RAPN and 71 OPN cases were extracted; in addition, 58 cases of RAPN and OPN were selected via PSM. RAPN was superior to OPN in terms of estimated blood loss (10 g vs. 160 g, P < 0.001), ischemia time (23 min vs. 34 min, P < 0.001), and hospital duration (7 days vs. 12 days, P < 0.001). There were no significant differences in the incidence of perioperative complications or in the rate of positive surgical margins (both P > 0.05). With respect to functional outcomes, the rates of preservation of renal function at both 1 day and 3 months postoperatively were higher with RAPN than with OPN (85.3% vs. 69.1% and 93.3% vs. 85.6% respectively, both P < 0.001). Conclusion: In selected cases, RAPN with warm ischemia appears to preserve renal function equally well or better compared to OPN with cold ischemia.
