Authors: Aganesov A. G. , Aleksanyan M. M. , Gemdzhian E. G. 
Published: April 2024

Objective. To analyze and compare the results of treatment of lumbar spinal stenosis using minimally invasive unilateral decompression and classical laminectomy.Material and Methods. The retrospective comparative monocentric study included 68 patients (2 groups of 34 patients each) operated on in 2018–2021 for spinal stenosis in the lumbar spine who met certain eligibility criteria. Patients of one group were operated on using minimally invasive bilateral decompression through a unilateral approach, while patients in the other group were operated on using classical laminectomy. The results of surgical treatment were compared during 24 months by assessing pre- and postoperative indicators of the intensity of pain in the back and lower extremities using a 10-point VAS, and the patient’s functional activity – using the Oswestry index.Results. A statistically significant clinical effect of surgical treatment was noticed in both groups. At the end of the follow-up period, the results of back pain relief in the minimally invasive surgery group were significantly better (0.3 vs 0.9, respectively), and the improvement in functional activity was comparable to the laminectomy group (8.8 vs 9.8, respectively). A clinical effect of pain relief in the lower extremities was obtained in both groups (up to 1.2 and 1.4, respectively). The length of hospital stay, time to activation, and volume of blood loss were significantly lower in minimally invasive decompression group.Conclusion. Minimally invasive unilateral decompression of the spinal canal for lumbar spinal stenosis demonstrates a better effect in relieving back pain than classical laminectomy, with no significant difference in relieving pain in the lower extremities. The minimally invasive technique allows patients to rehabilitate as quickly as possible and return to everyday life and work. It has socio-economic advantages compared to classical laminectomy – a shorter period of activation and hospital treatment, and less blood loss.

Published: April 2024

Objective. To analyze methods contributing to the improvement of clinical and radiological outcomes of surgical stabilization of the lumbar spine in conditions of reduced bone mineral density (BMD).Material and Methods. A search for publications presenting the results of clinical studies of surgical treatment of patients with degenerative lesions of the lumbar spine and reduced BMD was conducted in English and Russian in the MEDLINE and Russian Science Citation Index (RSCI) databases using key words “osteoporosis”, “osteopenia”, “spinal surgery”, “spinal fusion” and related terms in titles and abstracts with a search depth of 20 years. After applying the inclusion and exclusion criteria, 17 clinical studies were selected for analysis.Results. Among the large number of techniques and implant-associated factors affecting the success of surgical intervention for degenerative lesions of the lumbar spine and reduced BMD, high-quality clinical studies have proven the effectiveness of expandable screws, spinal fusion with cortical screw placement and cement augmentation with polymethyl methacrylate.Conclusion. The combination of techniques for cortical pedicle screw placement, cement augmentation and the use of expandable screws makes it possible to achieve results in surgical treatment of patients with degenerative lesions of the lumbar spine with reduced BMD comparable with those in patients with normal BMD. Of particular importance is the preoperative assessment of the regional state of bone tissue, which should be carried out using quantitative CT or MRI studies.
Towards a sociolinguistics of in difference: stancetaking on others
Authors: Williams Quentin 
Published: April 2024

Abstract
This paper proposes a sociolinguistics of in difference, an inquiry-based approach to stancetaking on others. It describes how multilingual speakers in an online context orientate towards a stance-object and affiliate, align and negotiate difference through embodied performances, as part of advancing an ethics of responsibility for the other and aesthetic investments. In the analysis of such orientations, I draw on virtual interactional data to illustrate how in difference through stancetaking is entextualized in the aesthetic, embodied performance of parody, in so-called Coloured English, Kaaps and a mixture of other languages by an emerging R&B and pop group in Cape Town. I demonstrate how the group invest in embodied performances merge the material, linguistic, cultural and semiotic significance of the body to undermine fixity and categorization. But also, how push-back from YouTube commentators, influencers, reactors take up evaluative, affective and epistemic stances as they move from difference to in difference. I conclude with the argument that in order for us to take adequate account of an ethics of responsibility for the other and describing aesthetic investments in embodied performances we have to recalibrate our theoretical and methodological toolkit to understand what it means to use language with dignity, to encounter each other in spaces of dignity and to just be dignified in diversity.

Abstract

Objectives
Thrombosis in antiphospholipid syndrome (APS) involves in most cases the venous circulation. Why in some patients thrombotic APS affects the arterial circulation and in particular cerebral circulation is unknown. In previous studies, both patient characteristics and antiphospholipid antibody types and titers have been associated with arterial thrombosis. Aim of this study was to compare the clinical characteristics and laboratory findings of venous and arterial thrombotic APS from a large series of patients.

Methods
Data were retrieved from the Start 2 antiphospholipid, a multicenter prospective register of long-term collected data from Thrombosis Centers in Italy.

Results
Of 167 patients with thrombotic APS, 114 (68 %) had a venous and 53 (32 %) had an arterial event as first clinical manifestation. Several clinical characteristics and risk factors were different among groups in univariate analysis. Using logistic regression analysis, reduced creatinine clearance and hyperlipidemia were independent variable for the occurrence of arterial APS. Notably, no difference in antiphospholipid antibody profiles and aβ2-Glycoprotein I levels were found between groups. A higher adjusted global antiphospholipid syndrome score (aGAPSS) was found in arterial group indicating a possible high recurrence rate in arterial APS.

Conclusions
These data have pathophysiological and clinical implication since associated conditions might predispose patients to arterial rather than venous events and call to a close monitoring and treatment of arterial APS due to their increased tendency to recurrence.
Anxiety and depression during post covid-19 lockdown period among medical students, and it’s relation with stress and smartphone addiction in India

Published: April 2024

Abstract

Objectives
Medical profession, a competitive and ever-updating field which requires great commitment, imposes a stressful environment for students. Our study aimed to find the prevalence and factors associated with psychological illness.

Methods
A cross-sectional analytical study was done among medical students in Puducherry. A stratified random sampling strategy was incorporated to achieve a calculated sample size of 384. The presence of anxiety and depression, perceived stress and addiction to the phone were assessed using the Hospital Anxiety and Depression Scale, Perceived Stress Scale, and Smartphone Addiction Scale – short version. Prevalence of anxiety and depression was summarized as a proportion with a 95 % confidence interval (CI). The prevalence ratio (PR) for the factors associated was estimated using log-binomial regression.

Results
With the response from 383 students, the prevalence of anxiety and depression was 39.4 % (95 %CI: 34.5–44.3 %) and 26.6 % (22.2–31.1 %). Perceived stress was moderate in 68.2 % and high in 14 % of students. Higher age (aPR=1.49), female gender (aPR=1.22), tobacco or alcohol use (aPR=1.24), smartphone addiction (aPR=2.09) and high stress (aPR=1.93) were the predictors of anxiety among medical students in our study. Use of tobacco or alcohol (aPR=2.07), smartphone addiction (aPR=1.96) and high stress (aPR=1.72) were the predictors of depression.

Conclusions
Anxiety was more prevalent than depression among the medical students. Use of tobacco or alcohol, smartphone addiction and stress increase the risk of psychological morbidity. Medical training should have a module on coping mechanisms to overcome psychological illness and have better mental well-being.
Teacher emotions and the emotional labour of modern language (ML) teachers working in UK secondary schools

Published: April 2024

Abstract
The present paper seeks to explore the contextual factors shaping the emotional labour experiences of secondary school teachers and explain the ways these educators manage their emotions. Data were generated through a series of 20 in-depth, semi-structured interviews with modern language (ML) teachers in the UK. The findings showed that teachers experienced primarily negative forms of emotional labour and these experiences were driven by five interrelated contextual factors: the lack of institutional support, heavy workload, low perceived status of MLs, students’ lack of motivation, and classroom misbehaviour. To manage their emotions, the study reveals that teachers used a wide range of coping mechanisms such as suppression, venting, social support, positive reframing, and the development of positive student–teacher relationships. In light of our results, we call for the emotional dimension of teaching to be better integrated into training programmes, an improvement in working conditions and better support mechanisms for teachers.

Abstract

Objectives
The most suitable biochemical markers for therapy adjustment in patients with congenital adrenal hyperplasia are controversial. 11-Oxygenated androgens are a promising new approach. The objective of this study was to investigate the diurnal rhythm of 11-ketotestosterone in children and adolescents in saliva and to correlate it with salivary 17-hydroxyprogesterone.

Methods
Fifty-one samples of steroid day-profiles from 17 patients were additionally analysed for 11-ketotestosterone, retrospectively. All patients were treated in our university outpatient clinic for paediatric endocrinology between 2020 and 2022. Steroid day-profiles of 17 patients could be examined. The cohort showed a balanced sex ratio. The median age was 13 years. The measurements for 17-hydroxyprogesterone were carried out during routine care by immunoassay. The measurements of 11-ketotestosterone were performed from frozen saliva samples using an implemented in-house protocol for liquid chromatography–tandem mass spectrometry (LC-MS/MS). The most important outcome were the absolute values for 11-ketotestosterone, their diurnal rhythmicity and the correlation with 17-hydroxyprogesterone.

Results
Both steroids show a circadian diurnal rhythm. 17-hydroxyprogesterone and 11-ketotestosterone correlate significantly. 11-Ketotestosterone showed a positive correlation with BMI at all times of the day.

Conclusions
11-Ketotestosterone shows circadian rhythmicity in our cohort and correlates with 17-hydroxyprogesterone. These findings serve as an important basis for prospective research into 11-oxygenated androgens as therapeutic markers in paediatrics. However, 11-ketotestosterone appears to be very dependent on BMI.

Abstract
The Wroughton’s free-tailed bat (Otomops wroughtoni) is classified as Data Deficient under IUCN Red List due to inadequate information on its distribution, population, and ecology. The species was previously recorded from Belgaum district of Karnataka and from East Khasi Hills and Jaintia Hills districts of Meghalaya and from Cambodia, represented by a single specimen. Through our study on Chiroptera taxa across 19 Community Reserves between October 2021 and January 2022 using physical search, mist netting and acoustic study we have identified a new colony of O. wroughtoni from the Mikadogre village in South Garo Hills District of Meghalaya, which extends the current distribution to 135 km from the nearest known distribution site. Interestingly, unlike other known roosts of O. wroughtoni which are in large caves with high roofs and deep crevices or cupolas, this roost was in the open limestone cliff located next to a stream. In addition to this, we have also documented the breeding colony of the species from a previously known site at Pynurkba. This new finding emphasises that there are more potential roosts across the Northeast region of India with similar habitats and altitudes waiting to be identified.

Abstract

Ex vivo liver resection combined with autologous liver transplantation offers the opportunity to treat otherwise unresectable hepatobiliary malignancies and has been applied in clinic. The implementation of enhanced recovery after surgery (ERAS) program improves the outcome of surgical procedures. This is a retrospective single-center study including 11 cases of patients with liver cancer that underwent autologous liver transplantation and received ERAS: cholangiocarcinoma of the hilar region (n = 5), intrahepatic cholangiocarcinoma (n = 3), gallbladder cancer (n = 1), liver metastasis from colorectal cancer (n = 1), and liver metastasis from gastrointestinal mesenchymal tumor (n = 1). There were no deaths within 30 days and major complications occurred in two patients, and four patients were readmitted upon the first month after the surgery. Median hospital stay was 20 days (range 13–44) and median open diet was Day 4 (range 2–9) after surgery and median early post-operative activity was Day 5 (range 2–9) after surgery. In conclusion, autologous liver transplantation is feasible in the treatment of otherwise unresectable hepatobiliary malignancies, and our study showed favorable results with autologous liver transplantation in ERAS modality. ERAS modality provides a good option for some patients whose tumors cannot be resected in situ and offers a chance for rapid recovery.
Das literarische Schaffen Manfred Winklers – Werkübersicht, Genese und Textpraktiken
Authors: Tempian Monica 
Published: April 2024

Abstract
Though awarded the Israeli Prime Minister’s Prize for Hebrew Literature in 1999, the multifaceted Manfred Winkler (1922–2014), encompassing roles as a German and Hebrew poet, survivor-writer, translator, painter, and sculptor, has only recently garnered sustained scholarly attention. This delayed recognition can be attributed, in part, to Winkler’s lifelong commitment to traversing geographical, national, ideological, and linguistic boundaries throughout his extensive career. It is only in the wake of a burgeoning interest in the life narratives of German-language refugees and immigrants to Israel, alongside their transcultural literary contributions, that the cultural and historical significance of Winkler’s poetry has come to light. This article delves into Winkler’s literary corpus and its inception, drawing upon the latest insights and research findings obtained through the author’s archival and editorial work since 2014. It provides an overview of the predominant themes, writing practices, and tendencies within the works of this multilingual author and (self-)translator. Winkler, through his poignant portrayal of the traumas of war and the memories of the Holocaust and the Jewish-Arab conflict – with a sense of grief rather than from a position of judgment – delineates the fault lines and pivotal moments of nearly the entire 20th century.
Enhanced Pb2+ adsorption using recyclable magnetic sodium alginate in a network structure for high renewable capacity
Authors: Dong Liming , Sun Hua , Wang Danfeng , Wang Shifan 
Published: April 2024

Abstract
This study presents the synthesis of a magnetic sodium alginate hydrogel for efficient adsorption of heavy metal ions. The hydrogel, composed of sodium alginate, demonstrates a network structure that facilitates effective metal ion adsorption. Utilizing magnetic forces, the hydrogel can be easily separated and regenerated, exhibiting excellent recyclability. Compared to traditional adsorbents, the magnetic sodium alginate hydrogel shows significantly improved adsorption capacity, particularly for Pb2+ ions. At pH ca. 4 and an adsorption time of 120 min, the hydrogel achieves a maximum adsorption capacity of 137 mg/g for Pb2+, with an adsorption rate of 83 %. The adsorption kinetics follow a pseudo-second-order equation, while thermodynamically, the process adheres to the Freundlich adsorption model, with capacity positively correlated with temperature and concentration. The negative ΔH value indicates an exothermic and spontaneous adsorption process. In competitive adsorption experiments, the hydrogel demonstrates strong selective adsorption towards Pb2+. It also exhibits excellent reusability, maintaining 80 % adsorption capacity after 10 cycles. The magnetic sodium alginate composite material possesses favorable recyclability and convenient magnetic separation properties, offering significant potential in various applications.
Women Who Stopped Working Due to Their Husband’s Opposition in Egypt
Authors: Iparraguirre Jose Louis , Hadi Zeina Amr Hosny Zaki Mohamed Abdel 
Published: April 2024

AbstractThis paper investigates a neglected reason underlying the low female labor participation rates in Egypt: husbands’ opposition. We find that opposition falls with increasing levels of educational attainment and chronological age of the husband. Age at first marriage, religious affiliation, wealth, and the extent to which a husband upholds traditional views regarding the participation of women in the labor market and gender equality in general were not significant. We also report an inverse relationship between the likelihood of husband’s opposition and the number of children in the household, which suggests that financial considerations may outstrip normative considerations.

Abstract

Objectives
Despite the fact that fibromyalgia, a widespread disease of the musculoskeletal system, has no specific treatment, patients have shown improvement after pharmacological intervention. Pregabalin has demonstrated efficacy; however, its adverse effects may reduce treatment adherence. In this context, neuromodulatory techniques such as transcranial direct current stimulation (tDCS) may be employed as a complementary pain-relieving method. Consequently, the purpose of this study was to evaluate the effect of pregabalin and tDCS treatments on the behavioral and biomarker parameters of rats submitted to a fibromyalgia-like model.

Methods
Forty adult male Wistar rats were divided into two groups: control and reserpine. Five days after the end of the administration of reserpine (1 mg/kg/3 days) to induce a fibromyalgia-like model, rats were randomly assigned to receive either vehicle or pregabalin (30 mg/kg) along with sham or active- tDCS treatments. The evaluated behavioral parameters included mechanical allodynia by von Frey test and anxiety-like behaviors by elevated plus-maze test (time spent in opened and closed arms, number of entries in opened and closed arms, protected head-dipping, unprotected head-dipping [NPHD], grooming, rearing, fecal boluses). The biomarker analysis (brain-derived neurotrophic factor [BDNF] and tumor necrosis factor-α [TNF-α]) was performed in brainstem and cerebral cortex and in serum.

Results
tDCS reversed the reduction in the mechanical nociceptive threshold and the decrease in the serum BDNF levels induced by the model of fibromyalgia; however, there was no effect of pregabalin in the mechanical threshold. There were no effects of pregabalin or tDCS found in TNF-α levels. The pain model induced an increase in grooming time and a decrease in NPHD and rearing; while tDCS reversed the increase in grooming, pregabalin reversed the decrease in NPHD.

Conclusions
tDCS was more effective than pregabalin in controlling nociception and anxiety-like behavior in a rat model-like fibromyalgia. Considering the translational aspect, our findings suggest that tDCS could be a potential non-pharmacological treatment for fibromyalgia.

El amplio despliegue que han tenido los estudios organizacionales en Latinoamérica plantea como desafío en­ten­der la vida organizacional marcada por un aumento de la precariedad del trabajo producto de la pandemia por COVID-19. Este artículo se propone analizar las estrategias de resistencia de los jóvenes trabajadores del sindicato Starbucks Chile en un escenario de crisis social y económica. Para esto, se realizó una etnografía organizacional en las ciudades de Santiago y Valparaíso entre marzo de 2022 y mayo 2023. Los resultados de este estudio se presentan a través de las siguientes catego­rías: a) Organización sindical en el marco del estallido social y pan­de­mia; b) Nos organizamos y nos movilizamos por un Chile sin traba­jadores precarizados; c) Organización más allá de nuestras fronteras: Primer encuentro internacional de comida rápida. A partir de estos resultados, son diversas las posibilidades analíticas que se pueden continuar desarrollando desde una perspectiva etnográfica. Se concluye que los jóvenes han configurado nuevas subjetividades políticas desde una dimensión discursivo-ideológica, centrando su actuar en la protesta social y las redes sociales, proyectando un avance hacia una inter­nacional de trabajadores de comida rápida.
