Study on overburden failure law and surrounding rock deformation control technology of mining through fault
Authors: Zeng Chunlin , Zhou Yuejin , Zhang Leiming , Mao Donggui , Bai Kexin
Published: January 2022

In the mining process of working face, the additional stress generated by the fault changes the law of roadway deformation and failure as well as the law of overburden failure. Aiming at the influence of the fault in the mining process of working face, this study introduced the geological strength index (GSI) to analyze the stress distribution in the elastic-plastic zone of the surrounding rock of the roadway. And similar experiments under different engineering backgrounds were combined to study the characteristics of overburden movement and stress evolution. Based on the conclusions obtained, the roadway support scheme was designed. This study shows that, compared with ordinary mining, through-the-fault mining causes slippage and dislocation of the fault, the load of the overburden is transferred to both sides of the fault, and the stress near the fault accumulates abnormally. The “three zones” characteristics of the overburden movement disappear, the subsidence pattern is changed from "trapezoid" to "inverted triangle", and the influence distance of the advanced mining stress on the working face is extended from 20m to 30m. The instability range of roadway surrounding rock is exponentially correlated with the rupture degree of the surrounding rock. Through the introduction of GSI, the critical instability range of roadway surrounding rock is deduced to be 2.32m. According to the conclusion, the bolt length and roadway reinforced support length are redesigned. Engineering application shows that the deformation rate of the roadway within 60 days is controlled below 0.1~0.5mm/d, the deformation amount is controlled within 150mm, and the roadway deformation is controlled, which generally meets the requirements of use. The research results provide guidance and reference for similar roadway support.
Associations between anxiety and the willingness to be exposed to COVID-19 risk among French young adults during the first pandemic wave
Authors: Etilé Fabrice , Geoffard Pierre-Yves
Published: January 2022

The COVID-19 outbreak has generated significant uncertainty about the future, especially for young adults. Health and economic threats, as well as more diffuse concerns about the consequences of COVID-19, can trigger feelings of anxiety, leading individuals to adopt uncertainty-reducing behaviours. We tested whether anxiety was associated with an increase in willingness to be exposed to the risk of COVID-19 infection (WiRE) using an online survey administered to 3,110 French individuals aged between 18 and 35 years old during the first pandemic wave and lockdown period (April 2020). Overall, 56.5% of the sample declared a positive WiRE. A one standard deviation increase in psychological state anxiety raised the WiRE by +3.9 pp (95% CI [+1.6, 6.2]). Unemployment was associated with a higher WiRE (+8.2 percentage points (pp); 95% CI [+0.9, 15.4]). One standard deviation increases in perceived hospitalisation risk and in income (+1160€) were associated with a -4.1 pp (95% CI [-6.2, 2.1]) decrease in the WiRE and +2.7 pp increase (95% CI [+1.1, 4.4]), respectively. Overall, our results suggest that both psychological anxiety and the prospect of economic losses can undermine young adults’ adherence to physical distancing recommendations. Public policies targeting young adults must consider both their economic situation and their mental health, and they must use uncertainty-reducing communication strategies.
PCAT-UNet: UNet-like network fused convolution and transformer for retinal vessel segmentation
Authors: Chen Danny , Yang Wenzhong , Wang Liejun , Tan Sixiang , Lin Jiangzhaung , Bu Wenxiu
Published: January 2022

The accurate segmentation of retinal vessels images can not only be used to evaluate and monitor various ophthalmic diseases, but also timely reflect systemic diseases such as diabetes and blood diseases. Therefore, the study on segmentation of retinal vessels images is of great significance for the diagnosis of visually threatening diseases. In recent years, especially the convolutional neural networks (CNN) based on UNet and its variant have been widely used in various medical image tasks. However, although CNN has achieved excellent performance, it cannot learn global and long-distance semantic information interaction well due to the local computing characteristics of convolution operation, which limits the development of medical image segmentation tasks. Transformer, currently popular in computer vision, has global computing features, but due to the lack of low-level details, local feature information extraction is insufficient. In this paper, we propose Patches Convolution Attention based Transformer UNet (PCAT-UNet), which is a U-shaped network based on Transformer with a Convolution branch. We use skip connection to fuse the deep and shallow features of both sides. By taking advantage of the complementary advantages of both sides, we can effectively capture the global dependence relationship and the details of the underlying feature space, thus improving the current problems of insufficient extraction of retinal micro vessels feature information and low sensitivity caused by easily predicting of pixels as background. In addition, our method enables end-to-end training and rapid inference. Finally, three publicly available retinal vessels datasets (DRIVE, STARE and CHASE_DB1) were used to evaluate PCAT-UNet. The experimental results show that the proposed PCAT-UNET method achieves good retinal vessel segmentation performance on these three datasets, and is superior to other architectures in terms of AUC, Accuracy and Sensitivity performance indicators. AUC reached 0.9872, 0.9953 and 0.9925, Accuracy reached 0.9622, 0.9796 and 0.9812, Sensitivity reached 0.8576, 0.8703 and 0.8493, respectively. In addition, PCAT-UNET also achieved good results in two other F1-Score and Specificity indicators.

Authors: Chen Nan-Chieh , Chang Yu-Tang , Chang Po-Chih , Chen Cheng-Sheng , Lai Chung-Sheng
Published: January 2022

Background

Self-directed learning is the cornerstone of adult learning. The aim of the study was to investigate the improvement of core competency and increase interest to be a surgeon among medical students after a perioperative training through a structured learning with written record model. The mediating role of adult learning pattern on core competency was also examined.

Methods

A 2-week training protocol was based on a structural learning model which included a structured written record by the learner for postoperative immediate feedback. An adult learning questionnaire (ALQ) was developed to assess learners’ adult learning pattern and a clinical core competency questionnaire (CCCQ) was developed to assess learning outcomes. A two-way repeated measured of ANCOVA would be used to analyze the interaction effect of adult learning pattern and learning effect on learning outcomes.

Results

From Jan 2017 to Dec 2019, 412 medical students were enrolled in the study. The increase scores of CCCQ and a significant numbers of increase interest to be a surgeon were shown after the perioperative training. Two-way repeated measure ANOVA revealed that there were significant differences in change between pre- and post-CCCQ across four levels of ALQ (interaction effect F = 13.0, p <0.001). The more adult learning patterns medical students own, the more they will benefit from the training.

Conclusions

The structural learning with written record model provides an effective perioperative training represented with clinical core competency and increase the interest to be a surgeon in the future. Medical students with tendency of adult learning pattern would learn better.

Authors: Sarker Abdur Razzaque , Ali S. M. Zulfiqar , Ahmed Maruf , Chowdhury S. M. Zahedul Islam , Ali Nausad
Published: January 2022

Objectives

Out-of-pocket (OOP) payment is the major payment strategy for healthcare in Bangladesh, and the share of OOP expenditure has increased alarmingly. Dhaka is recognised as one of the fastest-growing megacities in the world. The objective of this study is to capture the self-reported illnesses among urban citizens and to identify whether and to what extent socioeconomic, demographic and behavioural factors of the population influence OOP healthcare expenditures.

Subject and methods

This study utilises cross-sectional survey data collected from May to August 2019 in urban Dhaka, Bangladesh. A total of 3,100 households were randomly selected. Simple descriptive statistics including frequencies, percentage, mean (95% CI), median and inter-quartile range were presented. Bivariate analysis and multivariate regression models were employed.

Results

We observed that acute illnesses (e.g., fever, flu/cough) were dominant among participants. Among the chronic illnesses, approximately 9.6% of people had diabetes, while 5.3% had high/low blood pressure. The richest quintile only spent 5.2% of their household income on healthcare, while the poorest households spent approximately six times more than the richest households. We noted that various factors such as marital status, religion, source of care, access to safe water, income quintile and even the location of households had a significant relationship with OOP expenditure.

Conclusions

Our findings can serve as important source of data in terms of disease- specific symptoms and out-of-pocket cost among urban citizens in Dhaka. The people belonging to wealthier households tended to choose better healthcare facilities and spend more. A pro-poor policy initiative and even an urban health protection scheme may be necessary to ensure that healthcare services are accessible and affordable, in line with the Bangladesh National Urban Health Strategy.
Rhythmic contraction but arrhythmic distension of esophageal peristaltic reflex in patients with dysphagia
Authors: Muta Kazumasa , Mittal Ravinder K. , Zifan Ali
Published: January 2022

Background

Reason for dysphagia in a significant number of patients remains unclear even after a thorough workup. Each swallow induces esophageal distension followed by contraction of the esophagus, both of which move sequentially along the esophagus. Manometry technique and current system of classifying esophageal motility disorders (Chicago Classification) is based on the analysis of the contraction phase of peristalsis.

Goal

Whether patients with unexplained dysphagia have abnormalities in the distension phase of esophageal peristalsis is not known.

Methods

Using Multiple Intraluminal esophageal impedance recordings, which allow determination of the luminal cross-sectional area during peristalsis, we studied patients with nutcracker esophagus (NC), esophagogastric junction outflow obstruction (EGJOO), and functional dysphagia (FD).

Results

Distension contraction plots revealed that swallowed bolus travels significantly faster through the esophagus in all patient groups as compared to normals. The luminal cross-sectional area (amplitude of distension), and the area under the curve of distension were significantly smaller in patients with NC, EGJOO, and FD as compared to normals. Bolus traverses the esophagus in the shape of an “American Football” in normal subjects. On the other hand, in patients the bolus flow was fragmented. ROC curves revealed that bolus flow abnormalities during peristalsis are a sensitive and specific marker of dysphagia.

Conclusion

Our findings reveal abnormality in the distension phase of peristalsis (a narrow lumen esophagus) in patients with dysphagia. We propose that the esophageal contraction forcing the swallowed bolus through a narrow lumen esophagus is the cause of dysphagia sensation in patients with normal contraction phase of peristalsis.

Published: January 2022

The potential occurrence of disease outbreaks during the hajj season is of great concern due to extreme congestion in a confined space. This promotes the acquisition, spread and transmission of pathogenic microorganisms and pneumococcal disease are one of the most frequent infections among Hajj pilgrims. This study aimed to assess the cost-effectiveness and budget impact of introducing the PPV23 to Malaysian Hajj pilgrims. A decision tree framework with a 1-year cycle length was adapted to evaluate the cost-effectiveness of a PPV23 vaccination program with no vaccination. The cost information was retrieved from the Lembaga Tabung Haji Malaysia (LTH) database. Vaccine effectiveness was based on the locally published data and the disease incidence specifically related to Streptococcus pneumoniae was based on a literature search. Analyses were conducted from the perspective of the provider: Ministry of Health and LTH Malaysia. The incremental cost-effectiveness ratios (ICER), cases averted, and net cost savings were estimated. Findings from this study showed that PPV23 vaccination for Malaysian Hajj pilgrims was cost-effective. The PPV23 vaccination programme has an ICER of MYR -449.3 (US$-110.95) per case averted. Based on the national threshold value of US$6,200-US$8,900 per capita, the base-case result shows that introduction of the PPV23 vaccine for Malaysian Hajj pilgrims is very cost-effective. Sensitivity analysis revealed parameters related to annual incidence and hospitalised cost of septicemia and disease without vaccination as the key drivers of the model outputs. Compared with no vaccination, the inclusion of PPV23 vaccination for Malaysian Hajj pilgrims was projected to result in a net cost saving of MYR59.6 million and 109,996 cases averted over 5 years period. The PPV23 vaccination program could substantially offer additional benefits in reducing the pneumococcal disease burden and healthcare cost. This could be of help for policymakers to consider the implementation of PPV23 vaccination for Malaysian performing hajj.

Published: January 2022

Background

Undernutrition is one of the serious health problems among adolescents in India where 253 million adolescents are in the age group of 10–19 years. Since adolescents represent the next generation of adults, it is important to understand the nutritional status of adolescents. Even though several studies have been carried out in different states in India on adolescent undernutrition (stunting, wasting /underweight), there is no study or review that estimated the national pooled prevalence of adolescent undernutrition and its determinants. Therefore, this review aims to determine the pooled prevalence and determinants of undernutrition (stunting, underweight/wasting) among Indian adolescents.

Methods

A systematic review of eligible articles will be conducted using preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. A comprehensive searching of the literature will be made in Pub Med, EMBASE, SCOPUS, Google, Google Scholar, and Cochrane databases. The quality of the articles included in the review will be evaluated using the Newcastle-Ottawa Scale (NOS) for observational studies in meta-analyses. The pooled prevalence and odds ratio of the associated risk factors or determinants with their 95% confidence interval will be computed using STATA version 16 software. The existence of heterogeneity among studies will be assessed by computing p-values of Higgins’s I2 test statistics and Cochran’s Q-statistics based on chi-square with a 5% level of significance among reported prevalence. Sensitivity analysis and subgroup analysis will be conducted based on study quality to investigate the possible sources of heterogeneity. Publication bias will be assessed through visual examination of funnel plots and objectively by Egger’s regression test. This review protocol has been registered at PROSPERO (CRD42021286814).

Discussion

By collecting and summarizing information on adolescent undernutrition can be a step towards a better understanding of the prevalence of nutritional status of Indian adolescents and how the associated factors influence the prevalence of undernutrition. This review will provide directions for further research and healthcare practitioners. This summarized finding at the national level will provide impetus to build nutritional strategies and proper healthcare services to fight against undernutrition among the most ignored population.
Repeated glucose spikes and insulin resistance synergistically deteriorate endothelial function and bardoxolone methyl ameliorates endothelial dysfunction
Authors: Ogiso Kazuma , Shayo Sigfrid Casmir , Kawade Shigeru , Hashiguchi Hiroshi , Deguchi Takahisa , Nishio Yoshihiko
Published: January 2022

Background

Both insulin resistance and postprandial glucose spikes are known for their potential to induce vascular endothelial dysfunction in individuals with metabolic syndrome. However, these factors are inextricable, and therefore, their relative contributions to inducing endothelial dysfunction remain elusive. In this study, we aimed to disentangle the effects of these factors and clarify whether bardoxolone methyl (CDDO-Me), a novel nuclear factor erythroid 2-related factor 2 (Nrf2) activator, protects against glucose spike-induced endothelial dysfunction.

Methods

We induced glucose spikes twice daily for a duration of 1 week to rats fed a standard/control diet (CD) and Western-type diet (WTD). Endothelium-dependent relaxation (EDR) was evaluated using isolated thoracic aortas. Gene expression and dihydroethidium (DHE)-fluorescence studies were carried out; the effect of CDDO-Me on aortic endothelial dysfunction in vivo was also evaluated.

Results

Neither WTD-induced insulin resistance nor pure glucose spikes significantly deteriorated EDR. However, under high-glucose (20 mM) conditions, the EDR of thoracic aortas of WTD-fed rats subjected to glucose spikes was significantly impaired. In this group of rats, we observed significantly enhanced DHE fluorescence as a marker of reactive oxygen species, upregulation of an oxidative stress-related gene (NOX2), and downregulation of an antioxidant gene (SOD2) in the thoracic aortas. As expected, treatment of the thoracic aorta of this group of rats with antioxidant agents significantly improved EDR. We also noted that pretreatment of aortas from the same group with CDDO-Me attenuated endothelial dysfunction, accompanied by a correction of the redox imbalance, as observed in gene expression and DHE fluorescence studies.

Conclusions

For the first time, we showed that insulin resistance and glucose spikes exert a synergistic effect on aortic endothelial dysfunction. Furthermore, our study reveals that CDDO-Me ameliorates endothelial dysfunction caused by glucose spikes in a rat model of metabolic syndrome.
Turnip mosaic virus co-opts the vacuolar sorting receptor VSR4 to promote viral genome replication in plants by targeting viral replication vesicles to the endosome

Published: January 2022

Accumulated experimental evidence has shown that viruses recruit the host intracellular machinery to establish infection. It has recently been shown that the potyvirus Turnip mosaic virus (TuMV) transits through the late endosome (LE) for viral genome replication, but it is still largely unknown how the viral replication vesicles labelled by the TuMV membrane protein 6K2 target LE. To further understand the underlying mechanism, we studied the involvement of the vacuolar sorting receptor (VSR) family proteins from Arabidopsis in this process. We now report the identification of VSR4 as a new host factor required for TuMV infection. VSR4 interacted specifically with TuMV 6K2 and was required for targeting of 6K2 to enlarged LE. Following overexpression of VSR4 or its recycling-defective mutant that accumulates in the early endosome (EE), 6K2 did not employ the conventional VSR-mediated EE to LE pathway, but targeted enlarged LE directly from cis-Golgi and viral replication was enhanced. In addition, VSR4 can be N-glycosylated and this is required for its stability and for monitoring 6K2 trafficking to enlarged LE. A non-glycosylated VSR4 mutant enhanced the dissociation of 6K2 from cis-Golgi, leading to the formation of punctate bodies that targeted enlarged LE and to more robust viral replication than with glycosylated VSR4. Finally, TuMV hijacks N-glycosylated VSR4 and protects VSR4 from degradation via the autophagy pathway to assist infection. Taken together, our results have identified a host factor VSR4 required for viral replication vesicles to target endosomes for optimal viral infection and shed new light on the role of N-glycosylation of a host factor in regulating viral infection.
Herpes simplex virus-1 utilizes the host actin cytoskeleton for its release from axonal growth cones
Authors: Danastas Kevin , Larsen Ava , Jobson Sophie , Guo Gerry , Cunningham Anthony L. , Miranda-Saksena Monica
Published: January 2022

Herpes simplex virus type 1 (HSV-1) has evolved mechanisms to exploit the host cytoskeleton during entry, replication and exit from cells. In this study, we determined the role of actin and the molecular motor proteins, myosin II and myosin V, in the transport and release of HSV-1 from axon termini, or growth cones. Using compartmentalized neuronal devices, we showed that inhibition of actin polymerization, but not actin branching, significantly reduced the release of HSV-1 from axons. Furthermore, we showed that inhibition of myosin V, but not myosin II, also significantly reduced the release of HSV-1 from axons. Using confocal and electron microscopy, we determined that viral components are transported along axons to growth cones, despite actin or myosin inhibition. Overall, our study supports the role of actin in virus release from axonal growth cones and suggests myosin V as a likely candidate involved in this process.
Crisscrossing through critical fashion studies: Inclusive and interdisciplinary intersections
Authors: Smelik Anneke , Kaiser Susan B.
Published: January 2022

In this introduction to the 12.2 issue of Critical Studies in Fashion & Beauty, the editors preview and consider several crisscrossing themes across the articles and reviews: affect, the body and gender, as well as class, race, nationality and other subject positions. The articles and reviews also represent a range of places and times. Diversity and heterogeneity of themes and objects of enquiry are distinctive characteristics of critical fashion studies today. The crisscrossing of themes reflects an equal amount of crisscrossing of theories, methodologies and epistemologies in our highly interdisciplinary field. Crisscrossing can be described as intersecting paths that diverge in different directions at each crossroad or intersection. Imagine for example an irregular embroidery cross-stitch pattern: while emphasizing intersections, there may be differences in the lengths of the stitches and the ways in which they are arranged. The cross-stitches may be shaped in nonlinear formats, even more so when they are not so tidy and – instead – are random, abstract or ambiguous. The editors argue that the importance of ambiguity has long been a theme in critical fashion studies.
Indymedia and Standing Rock: Media-historic moments
Authors: Kidd Dorothy
Published: January 2022

This article reviews the legacy of the global Indymedia Center (IMC), a news and information network of 175 autonomous media centres that operated in every world region autonomously of the dominant corporate and public service communications and information systems. Emerging first during protests against the neo-liberal practices of the World Trade Organization, the IMC represented a media-historic moment, one of the first times that social movement media activists were able to bypass the dominant media to produce their own reports and circulate them directly to activists and supporters around the world. My review examines the composition of the IMC’s infrastructure and volunteer force, and their technological and communications repertoires in relation to the dominant communications systems, and consider their legacy in succeeding cycles of social movement contention. I then compare the legacy of the IMC with the more recent media-historic moment of the Standing Rock Sioux water protectors who in 2016 tactically employed a land-based mobilization with a movement-directed online and offline communications assemblage to mobilize against the construction of the Dakota Access Pipeline on their traditional territory. Capturing more US and international dominant media attention than any previous Indigenous movement, and reaching even more people with their self-generated media, they countered the neo-liberal extractivist paradigm of resource exploitation and also affirmed their Indigenous sovereignty, history and knowledge systems. Finally, I summarize some of the similarities and differences between the two cases and suggest questions for further study.

La evaluación de la producción científica a debate
Authors: García Peñalvo Francisco José
Published: January 2022

El año 2021 nos ha traído varias novedades en los productos que se utilizan para evaluar la calidad de las revistas académicas y por transitividad la producción científica de los investigadores porque se continúa dando un gran peso de las métricas de revistas frente a las métricas basadas en los artículos. Hay muchas voces a nivel internacional que piden un cambio en este sentido y que reclaman alejarse de los índices de impacto. Sin embargo, la realidad es que todavía seguimos muy vinculados a este tipo de indicadores. Desde la revista Education in the Knowledge Society (EKS) apoyamos y nos sumamos a cualquier iniciativa seria que avance en una mejor y más justa evaluación de la producción de los investigadores. En este sentido nuestra estrategia se orienta en dos direcciones. En primer lugar, seguiremos trabajando para que la revista esté posicionada en las principales bases con reconocimiento internacional, cuidando los procesos de revisión por pares para garantizar la calidad de los trabajos aceptados. Por otro lado, difundiremos los artículos publicados para que sean más visibles y haremos todo lo posible porque sus datos de citación sean claros porque hemos detectado que la calidad formal de las citas influye claramente en que se puedan atribuir las citas recibidas a las métricas a nivel de artículo. En lo que respecta a EKS, en 2021 se cerró el volumen 22 con 26 artículos publicados. En el contexto internacional se consiguió el primer índice SJR (Scopus) correspondiente al año 2020 (Q3) y en CiteScore (Scopus) la revista pasó de un percentil 27 (Q3) en la edición de 2019 a un percentil 81 (Q1) en la edición de 2020. Por su parte en Web of Science, con la publicación del nuevo Journal Citation Indicator (JCI) dentro del Journal Citation Reports (JCR), EKS está ubicada en un segundo cuartil (Q2) en los cuatro años para los que se ha calculado este indicador (2017-2020). En el listado de las 100 revistas en español de Google Scholar, la revista aparece en la posición 46. Por último, en el panorama nacional, EKS ha conseguido en 2021 el Sello de Calidad Editorial y Científica FECYT, y en el ranking de Revistas de Humanidades y Ciencias Sociales con sello FECYT ocupa un segundo cuartil. En Dialnet Métricas EKS aparece clasificada en el primer cuartil. El contenido de este artículo se encuentra tanto en español como en inglés.
Proportion of Vitamin D Deficiency in Subjects with Excessive Day Time Sleepiness in a Tertiary Care Psychiatric setting in Thiruvananthapuram
Authors: J. Devika , Nair Arun B.
Published: January 2022

BACKGROUND The role of vitamin D in normal human physiology has garnered a lot of discussions lately. It is now considered that Vitamin D exerts multiple effects beyond its role in bone physiology. Growing evidence suggests an association between hypovitaminosis D and sleep disorders, thus increasing the interest in the role of this vitamin in sleep. Vitamin D receptors have been found in the brain regions involved in sleep regulation, and vitamin D appears to be involved in regulating the sleep wake cycle. The study intended to explore the proportion of patients with excessive daytime sleepiness having vitamin D deficiency. METHODS This was a cross sectional study conducted in an urban primary care psychiatric clinic. The vitamin D levels of seventy-five patients who attended the clinic with complains of decreased sleep between the ages of 20 -75 years was collected. Their sleep score was assessed using Epsworth sleepiness scale and proportion with their vitamin D deficiency was analysed. RESULTS Of the 75 patients, 40 (53.3 %) were males and 35 (46.7 %) were females. The average vitamin D of the population was 16.62 with a standard deviation of 9.17. (16.62 ± 9.17). Of the analysed patients 13 (17.3 %) had severe vit D deficiency, 40 (53.3 %) had moderate deficiency and 19 (25.3 %) had mild deficiency. 3 (4 %) patients had normal vitamin D levels. CONCLUSIONS Vitamin D has both a direct and an indirect role in the regulation of sleep. Although vitamin D deficiency has been associated to sleep disorders, there is still scant evidence to concretely support the role of vitamin D supplementation in the prevention or treatment of sleep disturbances; indeed, more intervention studies and RCT are needed to better clarify these aspects. KEY WORDS Vitamin D, Deficiency, Sleep Disorders, Adults
A Comparative Study of Dynamic Hip Screw Versus Proximal Femoral Nailing in Surgical Management of Trochanteric Fractures in a Tertiary Care Centre, Thrissur District, Kerala
Authors: D.J. Abino , C.V. Krishnakumar
Published: January 2022

BACKGROUND Intertrochanteric fractures account for approximately half of the hip fractures in the elderly. Safe and efficient restoration of mobility is the goal of the treatment of intertrochanteric fractures. At the same time, we need to reduce the medical complications, and finally restore the patient to the pre-operative status. Dynamic hip screw gives good results but is sometimes not suitable particularly in unstable intertrochanteric fractures. The objective of this study was to compare dynamic hip screw and proximal femoral nail with respect to their functional and radiological outcomes during surgical management of the trochanteric fracture. METHODS A prospective study was conducted among 100 patients admitted with trochanteric fracture, in Government medical college, Thrissur, out of which 50 patients underwent fixation with proximal femoral nail and 50 with dynamic hip screw. Using proforma, socio-demographic details, details of admission, mode of trauma, details of fracture and surgery, complications and Harris hip score were assessed, minimum follow up was 6 months following surgery and longest follow up was 12 months. RESULTS Functional outcome was assessed with Harris hip score, and of the patients treated with dynamic hip screw, 28 % had a good score, whereas in patients treated with proximal femoral nail 42 % had good score (P-value 0.019), a significant difference was found between duration of non-weight bearing and type of fixation, also there was a significant difference in Harris Hip Score (P-value of 0.0001) CONCLUSIONS The proximal femoral nail (PFN) group had better functional outcomes both radiologically and clinically.

BACKGROUND Diabetic retinopathy is becoming one of the common blinding disease in the world affecting people in both developing and developed countries.Basic mechanism thought to be of advanced glycation end products and othertoxic mediators causingtissue destruction and pathological process. Antioxidants have a major role in preventing this pathological process. Among various antioxidants some of the common blood products have thought to have a role. One among them is serum bilirubin. This study is done to know the correlation of diabetic retinopathy and serum bilirubin levels and thus know its importance in future in preventing progression of this blinding disease. METHODS A cross sectional study was done among OPD patients with type 2 diabetes for a period of one year. Inclusion criteria were diagnosed cases of type 2 diabetes for more than 1 year and age above 40 years. Exclusion criteria included all systemic diseases/drugs affecting liver function tests, confounding factors affecting serum bilirubin levels, extremely poor glycemic control and subjects in whom fundus was not visible due to media opacities excluding causes linked with diabetic retinopathy. After taking consent, detailed history and ophthalmic evaluation, venous blood was drawn and sent for serum bilirubin analysis. Diabetic retinopathy was classified according to ETDRS classification. Statistical study was done after compiling data. RESULTS Among the study subjects – 38.2% were diabetics. Common age group was 51 to 60 years with incidence of diabeties more in males 64.3%. Among diabetic retinopathy noted– mild NPDR was 31%, moderate NPDR was 35.7%, severe NPDR was 11.9%, very severe NPDR was 4.8% and PDR was 16.6 % respectively. The mean serum total bilirubin levels in non DR was 0.597 ± 0.17, mild NPDR was 0.4 ± 0. 15, moderate NPDR was 0.36 ±0.12, severe NPDR was 0.36±0.17, very severe NPDR was 0.35±0.07, low risk PDR was 0.3±0.10 and high risk PDR was 0.32±0.15 respectively. CONCLUSIONS This study concluded that severity of diabetic retinopathy was inversely proportional to the total, direct and indirect serum bilirubin levels.

Carcinoid is an uncommon tumour in ovary comprising 0.1 % of primary ovarian neoplasms and 1 % of all carcinoid tumours. It was first described by Stewart et al. in 1939 following which many case reports have come out.1They usually occur in the peri-menopausal age. Primary ovarian carcinoids are usually unilateral, but can show a cystic teratoma or mucinous neoplasm in the same or opposite ovary. Histological variants include insular, stromal, trabecular, and mucinous among which insular is the most common type, and around 30 % of them are associated with a carcinoid syndrome. Insular type is reported to be more common in western countries, whereas trabecular / stromal cases are more reported in Asian countries. Most carcinoids in ovary are diagnosed as an incidental radiological finding as an abdominal or pelvic mass or they may present with typical carcinoid syndrome - diarrhoea, flushing, bronchospasm, oedema, increase skin pigmentation, carcinoid heart disease. Another uncommon presentation is severe constipation associated with peptide YY production in the tumour. The clinical behaviour of carcinoid ranges from indolent unrecognisable to highly active metastatic secretory tumours. Carcinoid ovary being an uncommon tumour presenting in an uncommon site with varied presenting features, clinical confusion may lead to delayed diagnosis and management for patient. This case report aims to describe the clinicopathologic features of primary carcinoid ovary presenting in a female with severe constipation.
Szabadság, demokrácia és politikai közösség : A republikánus-liberális vita
Authors:   , Tóth Szilárd
Published: January 2022

A disszertáció a mai republikánus politikafilozófusok liberalizmussal szemben szegezett kritikáit vizsgálja meg, és az az állítás mellett érvel, hogy ezek a kritikák jelentős részt eltúlzottak, mert hamis liberalizmus-képre építenek. A vitának mindenekelőtt három része van: az első a szabadságról és az egyenlőségről szól, a második a demokráciáról, a harmadik pedig a politikai közösségről. A mai republikánusok többsége – köztük Philip Pettit, Quentin Skinner és mások – úgy vélik, hogy a republikánus elmélet jobb szabadság- és ezzel összefüggésben egyenlőség-elmélettel rendelkezik, mint a tágan értett liberalizmus, adekvátabb demokrácia-képe van, és a társadalom megfelelő közösségi integrációjáról is védhetőbb nézeteket képes nyújtani. A disszertáció következtetése szerint ezek a vélekedések nem feltétlenül megalapozottak, de legalábbis nem általában véve azok. Pettit, Skinner és követőik pontosan azzal hibáznak, hogy a vita kedvéért túlságosan általánosítják az ideológiai ellenfeleik nézeteit, és lekicsinyítik a liberális elméletben rejlő potenciált. Valójában többnyire ez utóbbi elméletből is kihozhatók ugyanazok az álláspontok, amelyeket a mai republikánusok képviselnek. A három vitatéma esetében nem mindig ugyanaz a republikánus elmélet limitációjának oka. Először is, hiába másmilyenek a republikánus és liberális szabadságeszmények, ennek a szélesebb elméleti kontextust tekintve nincsen nagy jelentősége. A republikánusok dominancia-ellenes megfontolásai a liberalizmustól sem mindig idegenek. Csak éppen másik „címke” alatt futnak. Ezek az autonómia, de meg inkább az egyenlőség-elv. Ezekre hivatkozva a liberális elmélettel is kritizálható a domináló hatalom. Másodszor, a mai republikanizmusnak két fő demokráciaelméleti irányzata létezik: az egyik az intézmények fontosságát hangsúlyozó, általában „neorománnak” nevezett koncepció, a másik a néppárti irányzat. Mindkettőnek az a célja, hogy „participatívabb” alternatívát nyújtson a „deficitesnek” vélt liberalizmussal szemben. Bemutatom, hogy ez csak a néppárti irányzatnak sikerül. Valójában a neoromán demokráciaelmélet: sajátos fajta liberalizmus. Harmadszor, áttekintem, hogy a republikánusoknak milyen elképzeléseik vannak a közösségi integrációról, annak jellegéről, céljáról és hasznáról. Látni fogjuk, hogy akár az egalitárius és demokratikus elképzeléseik, ezek sem mindig mutatnak túl a liberális elméleten.

Published: January 2022

Este texto apresenta as bases normativas do programa Educação com Movimento. Uma iniciativa que, no contexto da educação pública do Distrito Federal, incorpora a educação física nos projetos político-pedagógicos de escolas da educação infantil. Almeja-se que o professor de educação física realize um trabalho integrado e interdisciplinar junto aos pedagogos na educação das crianças pequenas. Parte da história da educação pública da capital federal contextualiza o texto, antes de recuperar que o Educação com Movimento tem sua gênese em condicionantes histórico-políticos favoráveis. Sua constituição se deve aos avanços curriculares progressistas que o Distrito Federal viveu em meio à construção coletiva de um currículo. Notadamente, o programa anseia por um desenvolvimento em compasso com as suas diretrizes que sugerem como auspiciosas as contribuições da educação física na educação da infância na escola pública.
EDUCAÇÃO INFANTIL EM ESCOLAS DE ENSINO FUNDAMENTAL: HÁ ESPAÇO PARA BRINCAR E “SE-MOVIMENTAR”?
Authors: Elesbão Heloisa , De Borba Nunes Natália , Da Silva Camargo Maria Cecília
Published: January 2022

O corpo e o movimento são reconhecidos como potentes manifestações expressivas das crianças, dentre outras possíveis. É por meio da linguagem corporal e de movimento que as crianças constituem suas identidades e estabelecem relações com seus pares e adultos, sobretudo nas brincadeiras, contribuindo no que a literatura classifica como culturas infantis. Considerando a relevância do binômio corpo/movimento e a centralidade do brincar na Educação Infantil (EI), o presente artigo tem por objetivo identificar o lugar destinado pelas professoras ao brincar e ao “se-movimentar” no cotidiano de turmas desta etapa de ensino em escolas de Ensino Fundamental na Região Central do Rio Grande do Sul. As narrativas docentes evidenciaram que as professoras têm perspectivas distintas sobre a importância do brincar e do “se-movimentar” no cotidiano da EI, ora reconhecendo o corpo e o movimento como linguagem infantil, ora reduzindo o binômio como instrumento para o desenvolvimento de outras habilidades.
DIÁLOGOS COM O CANTAR-DANÇAR NA EDUCAÇÃO INFANTIL
Authors: Correia Adriana Martins
Published: January 2022

Este texto, de caráter ensaístico, pretende colocar em cena o diálogo entre o universo dos brinquedos cantados e o trato com cantar-dançar na Educação Infantil. Parte da ideia de que o uso dessas manifestações traz em seu bojo uma lógica disciplinar, a partir das cantigas tradicionais e do brinquedo cantado pedagógico. Contudo, na contemporaneidade este trato lida também com um outro produto que existe a partir da midiatização, que incorpora e mantém velhos discursos, ao mesmo tempo em que os ressignifica a partir de novos sentidos e estéticas, dentro da flexibilidade própria da sociedade de controle. O trabalho é construído a partir da articulação entre a experiência da autora na docência, debates com docentes em formação inicial e continuada na Universidade, colocados em perspectiva com a literatura a respeito das relações entre escola e poder, educação das infâncias e ensino da dança na escola. Ao final são apresentadas algumas propostas e experiências que buscam deslocar o cantar-dançar para fora dessa lógica prescritiva, vislumbrando a potência da criatividade das infâncias.

Published: January 2022

The subject of this research is the combination of local and national tasks of the transport complex of the Russian Far East in the context of the changing foreign policy of the state. The purpose of the study is to consider the demand for the services of the transport when performing local and national tasks. Local tasks are to provide the activities of the macroregional socio-economic system. The increase of trade with Asian countries within the framework of the «turn to the East» policy led to an increase in the cargo volume for the transport of the Far Eastern Federal District, aggravation of infrastructure problems. This carries risks of incomplete fulfillment of the local tasks
