Understanding the degradation mechanisms of InGaN/GaN multiple quantum well UV photodetectors submitted to different current stresses
Authors: Dalapati Pradip , Yamamoto Kosuke , Egawa Takashi , Miyoshi Makoto
Published: June 2021

The degradation characteristics of InGaN/GaN multiple quantum well (MQW) photodetectors (PDs) stressed at 100 and 200 mA over 480 h are investigated. We have observed that the luminescence intensity, short circuit current density, and open circuit voltage decrease strongly, whereas the leakage current increases intensely due to the constant current stress. The strong activity of the Mg dopant and trap-assisted tunneling under the direct current stress are critical factors in the degradation of InGaN/GaN MQW PDs. Further, the photocurrent spectroscopy results reveal that for 100 mA stress current, the peak value of relative external quantum efficiency (EQE) slightly increases due to the widening of the space–charge region while, for the 200 mA of stress current, the peak value of EQE decreases (

Published: June 2021

The use of UV-visible fluorescence of hair as a promising technique for a simple and rapid preliminary diagnosis of osteoporosis was proposed recently by us. The molecules proposed as potential markers in that work were keratin, elastin as well as vitamin D and A whose fluorescence occurs in the vicinity of an emission peak located around 485 nm. The aim of the work presented here is to confirm these preliminary results. For that, new measurements based on the LIBS (Laser Induced Breakdown Spectroscopy) technique were performed on the same samples and focused on monitoring the evolution of calcium concentrations in hair in relation to the disease. The results showed a strong correlation between the evolution of calcium concentrations and the fluorescence peak located around 485 nm. This new finding highlighted the important role that the calcium-containing protein S100A3, which is abundantly present in the hair cuticle, may play on the fluorescence spectrum.

Brain tumors in adults may be infrequent when compared with other cancer etiologies, but they remain one of the deadliest with bleak survival rates. Current treatment modalities encompass surgical resection, chemotherapy, and radiotherapy. However, increasing resistance rates are being witnessed, and this has been attributed, in part, to cancer stem cells (CSCs). CSCs are a subpopulation of cancer cells that reside within the tumor bulk and have the capacity for self-renewal and can differentiate and proliferate into multiple cell lineages. Studying those CSCs enables an increasing understanding of carcinogenesis, and targeting CSCs may overcome existing treatment resistance. One approach to weaponize new drugs is to target these CSCs through drug repurposing which entails using drugs, which are Food and Drug Administration–approved and safe for one defined disease, for a new indication. This approach serves to save both time and money that would otherwise be spent in designing a totally new therapy. In this review, we will illustrate drug repurposing strategies that have been used in brain tumors and then further elaborate on how these approaches, specifically those that target the resident CSCs, can help take the field of drug repurposing to a new level.
A clinical diabetes risk prediction model for prediabetic women with prior gestational diabetes
Authors: Man Bernice , Schwartz Alan , Pugach Oksana , Xia Yinglin , Gerber Ben
Published: June 2021

Introduction

Without treatment, prediabetic women with a history of gestational diabetes mellitus (GDM) are at greater risk for developing type 2 diabetes compared with women without a history of GDM. Both intensive lifestyle intervention and metformin can reduce risk. To predict risk and treatment response, we developed a risk prediction model specifically for women with prior GDM.

Methods

The Diabetes Prevention Program was a randomized controlled trial to evaluate the effectiveness of intensive lifestyle intervention, metformin (850mg twice daily), and placebo in preventing diabetes. Data from the Diabetes Prevention Program (DPP) was used to conduct a secondary analysis to evaluate 11 baseline clinical variables of 317 women with prediabetes and a self-reported history of GDM to develop a 3-year diabetes risk prediction model using Cox proportional hazards regression. Reduced models were explored and compared with the main model.

Results

Within three years, 82 (25.9%) women developed diabetes. In our parsimonious model using 4 of 11 clinical variables, higher fasting glucose and hemoglobin A1C were each associated with greater risk for diabetes (each hazard ratio approximately 1.4), and there was an interaction between treatment arm and BMI suggesting that metformin was more effective relative to no treatment for BMI ≥ 35kg/m2 than BMI < 30kg/m2. The model had fair discrimination (bias corrected C index = 0.68) and was not significantly different from our main model using 11 clinical variables. The estimated incidence of diabetes without treatment was 37.4%, compared to 20.0% with intensive lifestyle intervention or metformin treatment for women with a prior GDM.

Conclusions

A clinical prediction model was developed for individualized decision making for prediabetes treatment in women with prior GDM.
Perioperative patient safety management activities: A modified theory of planned behavior
Authors: Kim Nam Yi , Jeong Sun Young
Published: June 2021

Patient safety is an important healthcare issue worldwide, and patient accidents in the operating room can lead to serious problems. Accordingly, we investigated the explanatory ability of a modified theory of planned behavior to improve patient safety activities in the operating room. Questionnaires were distributed to perioperative nurses working in 12 large hospitals in Korea. The modified theory of planned behavior data from a total of 330 nurses were analyzed. The conceptual model was based on the theory of planned behavior data, with two additional organizational factors—job factors and safety management system. Individual factors included attitude, subjective norms, perceived behavioral control, behavioral intention, and patient safety management activities. Results indicated that job factors were negatively associated with perceived behavioral control. The patient safety management system was positively associated with attitude, subjective norm, and perceived behavioral control. Attitude, subjective norm, and perceived behavioral control were positively associated with behavioral intention. Behavioral intention was positively associated with patient safety management activities. The modified theory of planned behavior effectively explained patient safety management activities in the operating room. Both organizations and individuals are required to improve patient safety management activities.
Foreign aid and economic growth: Do energy consumption, trade openness and CO2 emissions matter? A DSUR heterogeneous evidence from Africa’s trading blocs
Authors: Hongxing Yao , Abban Olivier Joseph , Dankyi Boadi Alex
Published: June 2021

The paramount vision of every country or sub-regions is to attain economic growth and sustainable economic growth. The paradigm drift of studies into foreign aid and sustainable economic growth has shown conflicting results that play on researchers to fill the gap of knowledge void. The plurality of studies looked at economic growth and foreign aid in single countries. However, one of the major determinants of sustainable growth such as CO2emissions and trade goes beyond the boundaries of a country. Deductively, grouped countries or sub-regional studies are needed to ascertain the heterogeneous relationship and cross-sectional dependency among panels grouping. We fill these gaps with the recent empirical methodology to unveil the impact of foreign aid, CO2emissions, trade openness, and energy consumption on economic growth. Thus a percentage rise in foreign aid corresponds to different significant weights in all panel groupings with exception of Southern African Development Community, which unveiled a non-significant estimate. Whereas trade openness in all panel grouping indicated a significant weight on economic growth. An increase in CO2emissions has a significant material effect on economic growth in Common Market for Eastern and Southern Africa, Economic Community of West African States, and Community of Sahel-Saharan States. The impact of energy consumption on economic growth across the panel groupings was statistically significant with Common Market for Eastern and Southern Africa having the highest weight impact. These results obtained in this study indicate that foreign aid, energy consumption, trade openness, and CO2emissions are positively correlated with economic growth. Based on the finding, the significant of the policy implications suggested. (a) The need for a paradigm shift from fossil fuel sources to renewables is encouraged in the various trading blocs (b) The need to embrace carbon storage and capturing techniques to decouple pollutant emissions from economic growth on the continent’s growth trajectory.
The prevalence and correlates of pre-diabetes in middle- to older-aged Irish adults using three diagnostic methods
Authors: Junker Kate , Buckley Claire M. , Millar Seán R. , Flynn Sinéad , Harrington Janas M. , Kearney Patricia M. , Perry Ivan J.
Published: June 2021

Background and objectives

Type 2 diabetes is a leading cause of death and disability worldwide and pre-diabetes is a strong predictor of diabetes development. To date, studies estimating the prevalence of pre-diabetes in the Irish population are sparse and conflicting. Monitoring the prevalence of pre-diabetes and a knowledge of associated factors is required to inform policies and to prevent development of type 2 diabetes. Therefore, this research examined the prevalence and correlates of pre-diabetes in a sample of middle- to older-aged Irish adults using three different methods for diagnosis.

Materials and methods

The Mitchelstown Cohort Rescreen (2016/17) was a follow-up, cross-sectional study of the Mitchelstown Cohort Study (2010/11). 1,378 participants were recruited from a random sample of patients attending a single primary care centre. Pre-diabetes was defined using three diagnostic criteria: American Diabetes Association (ADA) glycated haemoglobin A1c (HbA1c) cut-offs between 5.7%–6.4% (39–46 mmol/mol), World Health Organization International Expert Committee (WHO-IEC) HbA1c cut-offs between 6.0%–6.4% (42–46 mmol/mol) and ADA fasting plasma glucose (FPG) cut-offs between 5.6–6.9 mmol/l. Univariate and multivariable logistic regression analyses were used to determine factors associated with pre-diabetes.

Results

The prevalence of pre-diabetes was found to be 43.9% (95% CI: 41.2%─46.5%), 14.5% (95% CI: 12.7%─16.5%) and 15.8% (95% CI: 13.9%─17.8%) according to HbA1c ADA, HbA1c WHO-IEC and FPG ADA definitions, respectively. Depending on diagnostic method, factors associated with pre-diabetes in univariate analyses included sex, age, marital status, health rating, education and poor diet quality. In multivariable analysis, subjects classified by the FPG ADA pre-diabetes criterion displayed the least optimal metabolic profile defined by overweight and obesity (OR = 2.88, 95% CI: 1.53–5.43), hypertension (OR = 2.27, 95% CI: 1.51–3.40) and low high-density lipoprotein cholesterol concentrations (OR = 1.75, 95% CI: 1.07–2.87).

Conclusions

The discordance between prevalence estimates according to method of diagnosis is concerning. A National Diabetes Prevention Programme is currently being developed in Ireland. Monitoring the prevalence of pre-diabetes over time will be important to assess the effectiveness of this programme. This study will inform national decision-makers on which definition of pre-diabetes to use for monitoring purposes.
Impact of Covid-19 on attendances for a 1st episode of reduced fetal movements: A retrospective observational study
Authors: Marques-Fernandez Laia , Sharma Swati , Mannu Una , Chong Hsu Phern
Published: June 2021

Background

Prior studies have demonstrated an increased stillbirth rate. It was suggested that the COVID-19 pandemic may have impacted on attendances for reduced fetal movements. Thus, we sought to ascertain the impact of the pandemic on attendances for reduced fetal movements (RFM) in our unit, ultrasound provision for reduced fetal movements, and the stillbirth rate.

Methods

This was a single site retrospective cohort study involving all women complaining of a 1st episode of reduced fetal movements between 01/03/2020-30/04/2020 (COVID) to 01/03/2019-30/04/2019 (Pre-COVID). Data were retrieved from computerised hospital records and statistical analyses were performed using GraphPad Prism and SPSS.

Results

22% (179/810) of women presented with a 1st episode of reduced fetal movements Pre-COVID compared to 18% (145/803) during COVID (p = 0.047). Primiparous women were significantly over-represented in this population with a 1.4-fold increase in attendances during COVID (67% vs 48%, p = 0.0005). Neither the total stillbirth rate nor the stillbirth rate amongst women who presented with reduced fetal movements changed during COVID. Ultrasound provision was not impacted by COVID with 95% of the scans performed according to local guidelines, compared to Pre-COVID (74%, p = 0.0001).

Conclusions

There is a significant decrease in 1st attendances for reduced fetal movements during COVID-19 pandemic. Primiparous women were 1.4 times more likely to attend with RFM. Women should be reassured that COVID-19 has not resulted in a decreased provision of care for RFM, and has not impacted on the stillbirth rate.
Current smoking alters phospholipid- and surfactant protein A levels in small airway lining fluid: An explorative study on exhaled breath

Published: June 2021

Small airways are difficult to access. Exhaled droplets, also referred to as particles, provide a sample of small airway lining fluid and may reflect inflammatory responses. We aimed to explore the effect of smoking on the composition and number of exhaled particles in a smoker-enriched study population. We collected and chemically analyzed exhaled particles from 102 subjects (29 never smokers, 36 former smokers and 37 current smokers) aged 39 to 83 years (median 63). A breathing maneuver maximized the number exhaled particles, which were quantified with a particle counter. The contents of surfactant protein A and albumin in exhaled particles was quantified with immunoassays and the contents of the phospholipids dipalmitoyl- and palmitoyl-oleoyl- phosphatidylcholine with mass spectrometry. Subjects also performed spirometry and nitrogen single breath washout. Associations between smoking status and the distribution of contents in exhaled particles and particle number concentration were tested with quantile regression, after adjusting for potential confounders. Current smokers, compared to never smokers, had higher number exhaled particles and more surfactant protein A in the particles. The magnitude of the effects of current smoking varied along the distribution of each PEx-variable. Among subjects with normal lung function, phospholipid levels were elevated in current smokers, in comparison to no effect of smoking on these lipids at abnormal lung function. Smoking increased exhaled number of particles and the contents of lipids and surfactant protein A in the particles. These findings might reflect early inflammatory responses to smoking in small airway lining fluid, also when lung function is within normal limits.

Introduction

The aim of this study was to report 36-month longitudinal changes using the North Star Ambulatory Assessment (NSAA) in ambulant patients affected by Duchenne muscular dystrophy amenable to skip exons 44, 45, 51 or 53.

Materials and methods

We included 101 patients, 34 had deletions amenable to skip exon 44, 25 exon 45, 19 exon 51, and 28 exon 53, not recruited in any ongoing clinical trials. Five patients were counted to skip exon 51 and 53 since they had a single deletion of exon 52.

Results

The difference between subgroups (skip 44, 45, 51 and 53) was significant at 12 (p = 0.043), 24 (p = 0.005) and 36 months (p≤0.001).

Discussion

Mutations amenable to skip exons 53 and 51 had lower baseline values and more negative changes than the other subgroups while those amenable to skip exon 44 had higher scores both at baseline and at follow up.

Conclusion

Our results confirm different progression of disease in subgroups of patients with deletions amenable to skip different exons. This information is relevant as current long term clinical trials are using the NSAA in these subgroups of mutations.

Reflexões de professoras de educação infantil sobre a condição feminina na docência
Authors: Penafiel Kelly Jessie Queiroz , Da Silva Claudiane Alencar , Zibetti Marli Lúcia Tonatto
Published: June 2021

A pesquisa teve como objetivo investigar como as professoras que atuam na Educação Infantil em escolas municipais de Vilhena, Rondônia, compreendem o seu próprio trabalho e as questões de gênero no âmbito da docência. O trabalhou seguiu a abordagem qualitativa e utilizou como instrumento de coleta de dados a entrevista. Participaram do estudo quatro professoras. Os resultados demonstram concepções reducionistas sobre o protagonismo feminino na docência e uma associação da figura materna, carinhosa e abnegada, ao ideal de professora. As constatações se sustentam na concepção da “inclinação natural” da mulher para o cuidado. É notório que a questão de gênero precisa ser explorada nos currículos dos cursos de formação inicial, aprofundando as discussões sobre o tema, com o objetivo de abandonar discursos e práticas que fomentam a desigualdade de gênero.
Exploring Factors Influencing Knowledge Sharing Mechanisms and Technology to Support the Collaboration Ecosystem A Review
Authors: Sensuse Dana Indra , Lestari Puri Indah , Hakim Shidiq Al
Published: June 2021

Knowledge sharing (KS) plays an essential role in enhancing performance and innovation within organisations, and many organisations implement various mechanisms and technology to support successful KS. It is therefore crucial for organisations to understand what factors might have an impact on the application of knowledge sharing for collaboration within their organisations. This study conducted a systematic literature review to investigate what mechanisms or technologies organisations use to share knowledge and what factors influence that usage. This systematic literature review used the Kitchenham method, selecting 19 articles as eligible for this study from a total of 853. The articles chosen were published between 2015 and 2020 and were retrieved from five popular databases: Science Direct, Scopus, IEEE, ACM Digital library, and Springer. The results of the conducted review found that trust, appreciation, management support, and organisational goals were factors that facilitated collaboration in KS. Among the mechanisms identified were the use of face-to-face meetings, employment of a chief knowledge officer, the implementation of technology to support KS, and collaboration on a webblog.

This paper aims to measure the extent to which Bangladesh-based Library and Information Science (LIS) researchers have published in leading LIS journals indexed by Web of Science (WoS) and SCOPUS. To answer this question, bibliographic information from LIS publications published in leading bibliographic databases from 1971 to 2020 were examined. Data from 266 LIS publication were collected, compiled and cleaned. VOSviewer software was used to carry out the science mapping of bibliometric networks. From the data it was evidenced that joint authorship and international collaboration have been increasing during this time frame. Authors from 20 countries have published in collaboration with Bangladeshi LIS researchers. Faculty members and the Department of Information Science and Library Management (ISLM) of Dhaka University became the most prolific authors and LIS Department in Bangladesh. The data compiled and findings will benefit current Bangladeshi LIS researchers and practitioners to assess areas of focus by highlighting, what they have, what they lack, and how they could grow to get direction for future research.
II. Kirchliche Zufluchtsorte im Frühmittelalter
Authors: Kasten Brigitte
Published: June 2021

Church Spaces for Refugees in Early Medieval Ages. The paper deals with the spatial regulations of asylum. It shows that the spacious area of asylum of Late Antiquity was considerably reduced by many gentile Germanic kings. However, with the increasing Christianisation and the founding of monasteries and regional churches, the ability to grant asylum was extended to these churches, whereas in Late Antiquity in the Western Roman Empire, very likely only the episcopal churches – partly due to the lack of too many other churches – were qualified to grant asylum. In this way, a harmonization between profane and ecclesiastical places of refuge took place for just as “all” churches were (before?) all royal courts and not only the king’s residence were spaces of refuge. In the case of church spaces of refuge, it increasingly became a qualitative requirement that the church building or its parts (altar, gates etc.) had been sanctified by episcopal ordination. The reduction in the size of the asylum area did not initially go hand in hand with an impairment in the right of asylum. The bishop’s (priest’s) obligation to intercede or right to intercede was only levelled under emperor Charlemagne with reference to the competence of any worthy person to intercede.
V. Carl Erdmann – ein deutschbaltischer Provinzialrechtler mit Idealen
Authors: Luts-Sootak Marju
Published: June 2021

Carl Erdmann − a German-Baltic provincial lawyer with ideals. Carl Eduard Erdmann (1841–1898), almost forgotten today, produced the most comprehensive work on the private law of the Baltic provinces of the Russian Empire in the late 19th century. With a good reason, he is considered the most outstanding philosophical mind among the Baltic provincial lawyers. His doctrines on the person and ownership in law are deeply rooted not in the modern philosophy of freedom, but in Christian ideals. The person had its ultimate justification in the divine personality. The idea of ownership was to be kept free from individualistic egoism and embedded in the generational continuity of the family. These ideals explain how Erdmann was able to combine his legal technique of German Pandektistik with the pre-modern normative guidelines of Baltic private law codification.
Rechtsgeschichtliche Botschaften aus der Frühgeschichte der Menschheit
Authors: Willoweit Dietmar
Published: June 2021

Legal-historical messages from the early history of mankind. Until now, archaeology has only rarely permitted generalizations of a legal-historical nature. The work of Hermann Parzinger, with its worldwide comparison of archaeological finds, now for the first time opens up the possibility of recognizing “laws of motion of early human history”. This includes the ability to cooperate on the basis of contractual agreements and the emergence of hierarchical orders. Evidence of violent conflicts also suggests that there must have been early mechanisms for conflict resolution within social groups.
Transkription ausgewählter Lösungen zu vier Fällen aus: Wilhelm Girtanner: Rechtsfälle zu Puchtas Pandekten, Jena 1852
Authors: Wolter Miriam
Published: June 2021

Four selected legal cases from Girtanner’s “Rechtsfälle zu Puchta’s Pandekten”: A transcript. In 1852, the first edition of Wilhelm Girtanner’s casebook “Rechtsfälle zu Puchta’s Pandekten” was published in three volumes. The work contains 480 legal cases for study purposes, interspersed with blank pages that presumably served as a space for students to jot down notes. The following is a selected transcript of such handwritten notes, left in a copy of Girtanner’s book by an unknown writer. These notes help shed some light on a specific approach to analyzing legal cases, namely one that centers conciseness and focusses on an exegesis of the Pandects.

Günümüzde bankalar, mevcut ve potansiyel müşterileri ile interaktif olarak iletişimde olma, onların ihtiyaçlarını tanımlama ve bu ihtiyaçlara uygun ürün ve hizmetler ile ilgili reklam yapma gibi amaçlarla sosyal medyayı pazarlama stratejilerinde bir araç olarak kullanmaktadır. Bu çalışmanın amacı, Türkiye’deki mevduat ve katılım bankalarının Instagram kullanımlarını müşteri ilişkileri ve pazarlama yönetimi perspektifinde değerlendirmektir. Bu bağlamda çalışmada, Miranda vd. (2013) tarafından geliştirilen Facebook Değerlendirme Endeksi (FAI) kapsam geçerlilik analizi yapılarak Instagram özelinde uyarlanmıştır. Popülerlik, etkileşim ve içerik olmak üzere üç parametrede değerlendirilen bu endeks aracılığıyla bankaların Instagram kullanımları nicel olarak karşılaştırılmıştır. Parametrelere ilişkin veriler içerik analizi yöntemi ile elde edilmiştir. Bu yöntem, ilgili bankaların Instagram hesaplarından alınan halka açık verilerin değerlendirilmesine dayanmaktadır. Sonuçlar Türkiye’deki bankaların 2015 ve öncesi döneme göre Instagram kullanımlarının artığını ancak bu bankaların sadece %36,7’sinin Instagram’ı müşteri etkileşimlerinde etkin bir şekilde kullandığını göstermektedir. Ayrıca etkin Instagram kullanımında takipçi sayısının tek başına yeterli olmadığı aynı zamanda paylaşılan gönderilerin içeriği ve bu gönderilere iletilen müşteri geribildirimlerinin de önemli bir yere sahip olduğu tespit edilmiştir. Çalışma sonuçları bankalara Instagram kullanımlarını rakipleri ile karşılaştırma imkânı tanıyarak sosyal medya pazarlamasında Instagram’ın geleceğine yönelik ipuçları sunmaktadır. Ek olarak çalışma, sosyal meyda pazarlaması araçlarından Instagram’ın sektörel bazlı kullanımına ilişkin veriler sunması bakımından literatüre katkı sağlamaktadır.

Published: June 2021

The purpose of this study is to examine whether brand love has a mediating effect on the relationship between brand experience and brand equity. The research data were obtained from 503 participants between the ages of 18-24 in Istanbul. Face-to-face survey technique was used as a data collection method, quota sampling and convenience sampling methods were preferred as the sampling method. The collected data were tested using exploratory factor analysis, confirmatory factor analysis and structural equation modelling analysis within the framework of the conceptual model of the research. According to the findings of the research, it has been determined that four dimensions of brand experience (sensory, emotional, intellectual and behavioral) have a positive effect on two dimensions of brand love (affection, passion) and four dimensions of brand equity (brand awareness, brand associations, perceived quality, brand loyalty). However, it was concluded that brand love has no mediating effect on the relationship between brand experience and brand equity.

The morphological and thermal properties of composites containing a bioplastic blend and micro/nano-sized biochar from pyrolyzed jatropha seeds from microwave pyrolyzed jatropha seeds were investigated using scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, and differential scanning calorimetry. The biocomposite samples exhibited a brittle structure with a slightly ductile chip-like appearance. The Fourier transform infrared spectroscopy results for the PLA/PEMA/BC bio-composites were comparable to the PLA/BC biocomposites. A lower bio-filler content had more pronounced peak intensities than the higher bio-filler content biocomposites. The added PEMA compatibilizer in the PLA/PEMA/BC biocomposite showed more pronounced peaks, which indicated slightly improved bonding/interaction between the bio-filler and the matrix. Overall, increasing bio-filler content did not drastically affect the functional groups of the biocomposites. Thermogravimetric and differential scanning calorimetry analysis showed the developed biocomposites had a slight improvement in thermal stability, in comparison to the PLA sample. Improvements in the thermal stability of the PLA/PEMA/BC biocomposite could be attributed to the additional hydroxyl group, which was due to the added PEMA in the PLA and PLA/BC. According to the results of the analysis of the developed biocomposites, the biocomposites were more brittle and had reasonable thermal stability.

Authors: Farida Nida
Published: June 2021

Central retinal artery occlusion (CRAO) is a blinding event but not considered as a common emergency problem. Since awareness of the case is low, patients usually come to the ophthalmologist later than the golden period and havingthe worst prognosis. We report the case of patient with a central retinal artery occlusion that had visual improvement after emergency treatment.A 47-year-old woman with no comorbidities presented with symptoms of a sudden blurred vision, no pain or redness in the right eye (RE). Best-corrected visual acuity in the RE was 1/60. A relative afferent pupillary defect was observed in the RE. Ocular fundus examination of RE was suggestive of CRAO. Emergency treatment were performed, including rebreathing of expired CO2, ocular massage and ocular chamber paracentesis. One week later, the visual acuity was improved.This case highlights that fast and accurate response in acute management of CRAO should be conducted, especially within the golden hours which is less than 6 hours after the accident, to prevent permanent visual loss of thepatient.

Introduction: Hypertension is a chronic disease which its presence is often not known until occurrence of other diseases. Several studies had previously investigated the relationship between vitamin D concentration and hypertension. However, no concluding result is obtained. This paper aimed to determine the relationship between vitamin D 25(OH)D concentration and hypertension onelderly at a public health clinic located at Reni Jaya, South Tangerang.Methods: This was cross-sectional study conducted in a public health clinic between January 2017 to January 2018. One hundred and fifty subjects were recruited by consecutive sampling after informed consent were obtained.Anamnesis, physical examination, and anthropometric measurement were performed by general practitioners. The following day serum vitamin D 25(OH)D examination were collected and examined at certied laboratory. The data werethen analyzed using Chi-Square test.Results : As many as 80 (53.4%) subjects had insufficient vitamin D 25(OH)D concentration (25-50 nmol/L). Stage I and II hypertension were found in 51 (34.0%) and 34 (22.7%) subjects, respectively. Age was significantly associated with hypertension (p=0.048). No significant association was observed between vitamin D 25 (OH)D and hypertension p=0.347.Conclusions: There was no significant association between serum vitamin D 25(OH)D and hypertension.

Objetivo. Describir los estudios actuales sobre calidad de vida en adultos jóvenes con TDAH diagnosticados por primera vez en la adultez o que no recibieron ningún tipo de tratamiento para dicho trastorno. Método. Se realizó una metasíntesis en investigaciones que reportan evidencias teóricas, metodológicas y concluyentes sobre el objeto de estudio, siguiendo recomendaciones de la red Cochrane y la declaración PRISMA. Resultados. Seis documentos seleccionados y analizados de 418 encontrados arrojaron que el TDAH afecta negativamente el bienestar personal, emocional, físico y material del adulto joven sin diagnóstico ni tratamiento durante la etapa infanto-juvenil. La gran mayoría de los adultos jóvenes con TDAH, principalmente aquellos con trastornos comórbidos, tienen una pobre valoración de su calidad de vida.

Published: June 2021

Resumen. Objetivo. Sistematizar los aportes de la escucha analítica con elementos psicodramáticos y corporales en un grupo de hombres que experimentaron violencia durante su infancia. Método. Sistematización y análisis por categorías temáticas, a partir de observación participante, registros escritos y de audio, del discurso verbal y corporal de 9 hombres en un grupo de terapia psicoanalítica con técnicas psicodramáticas. Resultados. Se concluye que la violencia promueve una relación de maltrato con el propio sujeto y la experiencia de dolor es inscrita en el cuerpo como posibilidad de expresión. El abordaje grupal facilitó la reelaboración del sufrimiento psíquico mediante el uso del cuerpo para reconocer y verbalizar emociones de la escena traumática en un encuentro de subjetividades.

Introduction. Rheumatoid arthritis (RA) is a chronic, systemic, autoimmune inflammatory disease of unknown origin, mainly affecting synovial joints and related structures, including the adjacent musculature, generating great disability and reduction in quality of life. Aim. This study was designed to investigate the effect of low-level laser therapy (LLLT) on gastrocnemius of Wistar rats subjected to an experimental model of RA. Material and methods. Forty male Wistar rats were used, separated into: acute and chronic, being subdivided into Control Group (CG): without intervention, Lesion Group (LG): submitted to lesion, Laser Control Group (LCG): without lesion and with treatment, and Laser Lesion Group (LLG): submitted to lesion and LLLT. The treatment with LLLT occurred in four points of the right knee, wavelength of 660 nm, energy density of 5 J/cm2, energy per point of 0.003 J. Morphometric analysis was performed using a 40x magnification photomicrograph and analyzed using the Image-Pro-Plus 6.0 program. Results. As result of the acute group there was a difference only for muscle mass, being higher in CG. For the chronic group there was significant difference for cross-sectional area, larger and smaller diameter, again with the control group obtaining higher values than the others, for the number of nuclei LG was lower than CG and LCG, but LLG was not different from any of them. Conclusion. It is concluded that treatment with LLLT was not very effective in reversing the harmful effects of RA on the gastrocnemius muscle.

Introduction. Occupational exposure to potentially infectious material (PIM) is a serious problem for healthcare workers, including medical students. Aim. We assessed the state of knowledge about occupational exposure and frequency of exposure among students of selected medical faculties in Poland. Material and methods. Retrospective analysis with proprietary questionnaires. Results. Only 34.5% from 753 respondents correctly indicated bloodborne pathogens and 9.3% PIM. There were 84 reports of exposure, mostly during intravenous injections. 10.4% students claimed probable occupational exposure which was not reported. Most common reason for not reporting was fear of negative supervisor reaction. Conclusion. Student’s knowledge of this matter is poor. Significant percentage of students has never participated in occupational exposure training. Occupational exposure was experienced by surprisingly large number of students. Students are afraid to report the incidents. Additional education would be useful in reducing exposure risk.
The Evolution of Moscow Conceptualism: From Early Kabakov to Later Pepperstein
Authors: Kusovac Jelena
Published: June 2021

This article considers the most important strategies, techniques, and concepts that formed in the Moscow artistic environment from the late 1970s until the present day. The author of the article focuses on the creative work of Pavel Pepperstein, an artist and writer who belonged to the group of young conceptualists. The artist adopts some of the conceptual strategies he inherited from his father V. Pivovarov, I. Kabakov, and A. Monastyrsky and develops them in his own manner, thus giving them special characteristics and his own features. The aim of the article is to show and enlarge the context of the artist’s oeuvre by analysing his collaborations with other Moscow conceptualists and social artists, paying special attention to the Medical Hermeneutics Inspection group founded by Pepperstein in 1987 with S. Anufriev and Yu. Leiderman. Apart from visual artistic forms, mainly graphics, installations, and performances, one of the main activities of the group were numerous theoretical treatises that addressed issues of aesthetical, philosophical, and linguistic discourse in conceptual and contemporary art, as well as the relationship between art and its interpretation.
