Separating aggregate discouraged and added worker effects: the case of a former transition country
Authors: Congregado Emilio , Gałecka-Burdziak Ewa , Golpe Antonio A. , Pater Robert
Published: September 2021

Research background: We analyse the added worker effect (AWE) and the discouraged worker effect (DWE) from an aggregate perspective. The first effect refers to an increase in labour force participation in response to a decrease in the wage rate. The second effect refers to the decision by workers who have been unsuccessful in their job search to leave the labour market or to decrease their labour force participation. For our analysis, we use the case of Poland, a country with a persistently low labour force participation rate.

Purpose of the article: While previous studies focused on the net of the two effects, we aim to analyse the two effects both separately and simultaneously. We propose a new approach for analysing the two effects. We generalise and model them as resulting from different shocks: (i) the AWE as the result of a negative wage income shock, and (ii) the DWE as the result of a positive job search time shock. The underlying assumption is that both shocks have at least a transitory effect on the labour force participation rate. However, we also track the potential long-lasting effects of these shocks, and we analyse the reactions of gender and age groups to them. While this approach demonstrates the robustness of our results, it also provides the range of the sensitivity, as it shows that there are large differences in the magnitude of the AWE and the DWE for different labour market cohorts.

Methods: We use the multivariate unobserved component model to extract the AWE and the DWE, and we then use VAR models, applying sign and exclusion restrictions to model the underlying shocks. We use quarterly data for Poland in 1995?2019. Most of these data come from the Labour Force Survey, while the rest come from Statistics Poland.

Findings & value added: In contrast to previous literature, which analysed only the net effect of the two effects, we model the AWE and the DWE separately. Contrary to the findings of previous research, our approach seems to confirm that both effects are simultaneously present in the labour market, and both effects influence the labour force participation rate. Thus, we find that both effects are significant. Specifically, we show that the AWE is stronger, but transitory; while the DWE is weaker, but long-lasting.
What affects employment by NGOs? Counteraction to precarious employment in the Polish non-profit sector in the perspective of COVID-19 pandemic crises
Authors: Mikołajczak Paweł
Published: September 2021

Research background: The precarious employment in non-governmental organizations has not been the subject of thorough scientific considerations so far. Meanwhile, the dominance of flexible forms of employment in an organization evokes a sense of instability, insecurity and uncertainty among employees. It weakens the relationship between staff and the organization, which, by not providing employees with prospects for permanent employment, creates a threat to its own development. The COVID-19 pandemic is reinforcing these fears as the situation in the labour market continues to deteriorate.

Purpose of the article: The purpose of this study is to identify the factors affecting NGOs employment of contract employees, as a key condition for crowding out precarious employment.

Methods: Logistic regression analysis was conducted based on a national representative survey of 1500 Polish NGOs.

Findings & value added: Its results indicate that NGOs are increasing the employment of contract staff in order to cope with the excessive bureaucracy of public administration. A stimulating impact on employment is also provided by difficulties in maintaining good staff and volunteers, as well as when there is no sense of security in running an organization. In turn, the lack of people ready to selflessly get involved in an organization's activities, as well as difficulties in accessing premises appropriate to NGOs both reduce the desire among staff to be employed full-time. The monitoring of precarious employment (PE) in NGOs is of key importance in the shaping and effectiveness of national policies aimed at improving the living standards of society as a whole. NGOs are an important element, as they fill the gaps remaining in the implementation of such policies. In the long term, improving the quality of full-time employment in such entities by reducing the barriers to their activity will increase their potential for fulfilling their social mission. To date, such barriers and their relation to employment have not been considered in research literature. However, a considerable proportion of employees in the Polish NGO sector may join the ranks of those excluded from employment and deprived of income due to the crisis on the job market caused by the COVID-19 pandemic. This article contributes to the existing literature and practice by identifying the influence of wide spectrum of barriers of NGOs activity on permanent employment.
Optimal Shift Scheduling at Ibu Pejabat Polis Daerah (IPD) Kuala Muda using Goal Programming
Authors: Syed Abas Sharifah FHahriyah , Bidin Jasmani , Abdul Nurul Aatikah
Published: September 2021

Many workplaces encounter complex problems in preparing an optimal work scheduling to meet the 24 hours work demand especially in shift working hours. The schedule needs to consider many constraints and multi objectives at the same time. A mathematical model such as Goal programming is able to cater this kind of problems. Thus, this study was designed to provide a systematic and optimal schedule for police officers at Criminal Unit, IPD Kuala Muda, Kedah. This study is aimed to formulate the best model for the shift rotating schedule of the police officers and to find the best way to optimize the police scheduling related to the limitations, requirements of the police   station and the preferences of the police. Lingo software is used to run the model. However, only one out of three goals set for the study was achieved. The new schedule obtained shows that all police officers have the same number of working days, which is 21 days in the 28-day planning period. The new schedule produced is better than the previous manual schedule since it takes less time to prepare it without neglecting the constraints involved. To improve efficiency and flexibility on the generated schedules, it is recommended to use other methods such as hybrid swarm-based optimization and many new limitations and preferences should be also considered in the analysis.
Network Automation using Ansible for EIGRP Network
Authors: Mohd Fuzi Mohd Faris , Abdullah Khairunnisa , Abd Halim Iman Hazwam , Ruslan Rafiza
Published: September 2021

Network automation has evolved into a solution that emphasizes efficiency in all areas. Furthermore, communication and computer networks rely on a platform that provides the necessary technological infrastructure for packet transfer through the Internet using routing protocols. The Enhanced Interior Gateway Routing Protocol (EIGRP) is a hybrid routing protocol that combines the properties of both distance-vector and link-state routing methods. The traditional technique to configure EIGRP is inefficient and requires repeated processes compared to the network automation concept. Network automation helps to assist network administrators in automating and verifying the EIGRP configuration using scripting. This paper implemented network automation using Ansible to configure EIGRP routing and advanced configuration in the GNS3 environment. This study is focused on automated scripting to configure IP Addresses to the interfaces, EIGRP routing protocol, a default static route and advanced EIGRP configurations. Ansible ran the scripting on Network Automation Docker and pushed the configurations to the routers. The network automation docker communicated with other routers via SSH. In the testing phase, the running configuration between the traditional approach and automation scripting in the Ansible playbook was compared to verify EIGRP configurations' accuracy. The findings show that Ansible has successfully deployed the configuration to the routers with no errors. Ansible can help network administrators minimized human mistakes, reduce time-consuming and enable device visibility across the network environment. Implementing EIGRP authentication and hardening process can enhance the network security level for future study.
Los anarquistas rusos de Golos Truda a mediados de los años ‘20
Authors: Piemonte Víctor Augusto
Published: September 2021

Un grupo de inmigrantes rusos anarquistas dio forma en 1917 a la Federación de Organizaciones Obreras Rusas de Sudamérica. Pese a su importancia para la historia de la inmigración y del anarquismo en la Argentina, la actividad de este grupo no resultó objeto de estudio. Este artículo tiene por objetivo recuperar y analizar la postura política plasmada en la actividad editorial de este grupo específico de inmigrantes a través de la lectura sistemática de Golos Truda, su órgano de prensa. Entre sus páginas primó el rechazo al comunismo soviético, con especial énfasis al control de los soviets ejercido por el estado y a la cruenta persecución de que fueron destinatarios los anarquistas a manos de los bolcheviques. Creado por y para anarquistas rusos en el exilio sudamericano, el periódico conservó una identidad política muy marcada, siendo su principal preocupación la situación de los anarquistas en la Rusia soviética y no el desarrollo del anarquismo en Sudamérica.
“Una realidad que llegó para quedarse”: La CTEP y el escenario emergente a partir de la Marcha de San Cayetano (2016)
Authors: Gonzalez Laureano Javier
Published: September 2021

En el siguiente artículo nos proponemos ver cómo a partir de la marcha de San Cayetano por Paz, Pan, Tierra, Techo y Trabajo (2016) se abrió un nuevo escenario social y político para la Central de los Trabajadores de la Economía Popular (CTEP). Aquí destacamos tres aspectos. En primer lugar, la visibilidad que cobró la organización, el sector social que representa y sus demandas. En segundo lugar, el rol de esta movilización en el fortalecimiento de los vínculos entre las diferentes organizaciones de la Economía Popular. Y, en tercer lugar, el acercamiento a otros sectores sociales, principalmente las organizaciones de trabajadores/as formales. Desde un abordaje cualitativo, contemplando las particularidades de la referencia religiosa, buscaremos comprender la significación de esta marcha para la CTEP y su lucha sectorial, en un contexto de reorganización del mapa político argentino por la llegada de la alianza Cambiemos al gobierno.
Dos sentidos de la democracia en el movimiento Teatro Abierto. Las instituciones y las calles en la “primavera democrática”
Authors: Manduca Ramiro Alejandro
Published: September 2021

Teatro Abierto constituye una referencia canónica a la hora de pensar los años de la transición de la última dictadura militar argentina a la democracia. En esta ocasión buscaremos abordar la etapa menos estudiada del movimiento, al calor del nuevo régimen político. Las preguntas que nos guiarán serán de qué modo fue entendido el mismo en el interior de Teatro Abierto, qué expectativas despertó y qué modos de intervención adoptaron sus distintos miembros. Analizaremos dos derivas: una de ellas, caracterizada por la inserción institucional de parte de los referentes históricos del movimiento; la otra, vinculada a la continuidad del mismo, pero bajo nuevas lógicas organizativas y estéticas que se desplegaron en espacios diversos: plazas, parques, hospitales psiquiátricos, casas tomadas y centros culturales barriales, entre otros. Será de particular interés para este trabajo analizar las diversas redes de afinidad que se fueron configurando, los cambios organizativos y las estéticas adoptadas.
“La nueva educación que los trabajadores queremos”. Luz y Fuerza Capital Federal y su proyecto de formación integral (1962-1975)
Authors: Scodeller Gabriela
Published: September 2021

El artículo se propone explorar la puesta en marcha del proyecto educativo que impulsó el Sindicato Luz y Fuerza Capital Federal en los años sesenta y setenta en Argentina. Como parte de su concepción de un “sindicalismo múltiple y de participación”, el mismo procuró la formación político-sindical de activistas y cuadros medios, pero también, una educación cultural integral que abarcase a toda la “familia lucifuercista” y a trabajadores de otros gremios. El lugar estratégico de la formación se anudaba a su meta por lograr una cada vez mayor participación de los trabajadores en los ámbitos de gestión empresarial y de poder estatal. A partir de un recorrido sustentado en fuentes documentales de la propia organización, se formulan una serie de interrogantes a los abordajes historiográficos sobre el período y se discute la necesidad de revisar ciertos supuestos e interpretaciones sobre actores y prácticas.

“¿Mollis o fortis femina?”: la ambigüedad del personaje de Briseida en la Historia Troyana Polimétrica
Authors: Miguens Agustina
Published: September 2021

El presente trabajo examinará la representación del personaje de Briseida en la Historia troyana polimétrica (HTP), tomando en consideración las diferencias con su fuente directa, el Roman de Troie, y las interpretaciones que podrían haber suscitado en sus contextos de circulación, la corte angevina del siglo XII y la castellana del XIV, respectivamente. Los temas principales de las obras son las armas y el amor, los cuales se ven sintetizados en el personaje de Briseida, la cautiva enamorada de Troylo, pero que luego lo olvida en favor del griego Diomedes. Aunque la trama amorosa tiene un importante desarrollo, en consonancia con los códigos del amor cortés, la volubilidad de Briseida es severamente reprochada por el narrador en un pasaje con una clara influencia del discurso misógino medieval. Allí se retoma el tópico de la mollis femina, la mujer de voluntad débil y cambiante, en contraste con la fortis femina, fuerte y constante. Esta última aparece identificada con la referencia a “una rica dama de rico rey”, que, según el texto y el contexto de recepción, puede interpretarse tanto como una dedicatoria a una dama de la corte, como a la Virgen María, modelo de virtud femenina.

Prevalence of Bacterial Vaginosis among Married Women in Kalar District, Iraqi Kurdistan Region
Authors: Mohammed- Amin Saman Mohammed
Published: September 2021

Abstract Bacterial vaginosis (BV) is an inflammatory disease, caused by polymicrobial infection, including pathogenic bacteria which replace the vaginal normal flora and finally this replacement causes manifestations of several physiological and clinical symptoms among women within different ages. BV has become one of the main problems that make woman patients visit gynecological and obstetric consultant hospitals in most country. The present study is designed to determine the causative pathogen and the prevalence of bacterial vaginosis among married women patients in Kalar district. This cross-sectional study was performed from the beginning of March to the mid April-2021 among women who attended Obstetrics and Gynecological governmental hospital and out-patient clinics in Kalar City. Intra vaginal swabs have been collected in sterile Amies transport medium sticks and processed for isolation and identification of bacterial species depending on colony morphology, Gram’s stain and microbiological analysis protocols. Then socio-demographic and gynaecologic data were collected by questionnaire. Out of the 108 participant women who suffered from Gynecological diseases, 67(62.03%) of them exhibited bacterial vaginosis. From the 73 different isolated colonies, 18 bacterial species were identified; coagulase-negative staphylococci (CoNS) were the predominant cause of BV (32.84%), followed by E. coli (14.93%), Staphylococcus aureus (13.43%), Klebsiella pneumonia (8.96) and Micrococcus luteus (7.46%), while Proteus spp. and some uncommon bacteria display (1.49%) for each of them. The socio-demographic analysis between positive and negative woman patients revealed that the association between all studied risk factors and BV were statistically significant (P value < 0.05) except the age factor which was statistically non-significant meaning that the age was not associated with BV. In addition, the clinical symptom analysis showed that abnormal vaginal discharge, lower back pain, dysmenorrhea and strawberry were significantly associated with BV (P value < 0.05), while the rest of other factor did not exhibit statistically significant association.
Citizen’s motivation in neighbourhood planning in North West England
Authors: Cao Xinxin , Sturzaker John
Published: September 2021

Although some researchers have addressed the question of what motivates citizens to become involved in lower tier planning in the UK, the phenomenon is not yet fully understood. A lack of hard data, combined with some mutually contradictory arguments in the field, makes for imperfect analysis, and this can potentially undermine the effectiveness of individual engagement in Neighbourhood Plans (NPs). This paper focuses on what motivates citizens to participate in the process of creating NPs in North West England, and explores past theories on individual motivation. This study achieved its research aims through extensive research of the relevant literature, combined with an empirical study of five neighbourhoods in North West England. The main conclusion drawn from the dissertation is that there are complex and multiple motivations of people participating in NPs, and these impetuses are affected by a range of political, environmental and socio-economic factors. This research offers opportunities to enhance the effectiveness of NPs for researchers and NP stakeholders alike.

Published: September 2021

Aims

Spontaneous coronary artery dissection (SCAD) is an emerging cause of acute myocardial infarction (AMI) in young women without a typical cardiovascular risk profile. Knowledge on SCAD is based on observational studies and is still scarce. The aim of this monocentric observational study was to evaluate the predisposing factors, clinical features and prognosis of SCAD patients.

Methods

Between 2013 and 2020, 58 patients with angiographic diagnosis of SCAD were identified in our centre with an overall prevalence of 0.9% among patients admitted for AMI (58 of 6414 patients).

Results

The mean age was 54 ± 11 years and the majority were women (n = 50, 86%) with one or fewer cardiovascular risk factors (n = 35, 60%). The prevalence of Fibromuscolar Dysplasia (FMD) was 39% (7 of 18 screened patients). The rate of major adverse cardiovascular and cerebrovascular events (MACCEs) was used to assess the prognosis. Out-of-hospital cardiac arrest because of ventricular fibrillation was observed in four (7%) patients. The majority of patients (n = 51, 88%) were treated conservatively without revascularization. The in-hospital and 30-day clinical course was uneventful in most patients (n = 54, 93%) with two cardiac deaths. During a median follow-up of 12 months, there were no further deaths. The global rate of SCAD recurrence was significant (n = 8, 14%) but predictors have not been identified.

Conclusion

Although overall survival seems good, SCAD is a potentially malignant, not rare disease, which can present with sudden cardiac death and not uncommon recurrence. Prognostic stratification and optimal management of SCAD patients remain to be defined.

Aim

There is lack of evidence regarding the screening role of ECG for sudden cardiac death (SCD) prevention. Our aim was to evaluate the prevalence of ECG abnormalities among teenagers according to sport participation and competitive status.

Methods

Eleven thousand nine hundred and forty-nine Italian pupils from 179 secondary schools (13–19 years) were consecutively enrolled. ECG abnormalities were divided into minor and major. Medical history, clinical examination and sport activity information were acquired. Further evaluations were suggested in case of major ECG abnormalities. Follow-up was performed at 2 years.

Results

N = 1945 (16%) pupils had ECG abnormalities. Major ECG abnormalities were detected in 13% of the cohort, minor in 34%. ECG abnormalities were more common in nonathletes compared with athletes. A diagnosis of cardiac disease was reached in 25 (1.6%) of the pupils with major ECG abnormalities.

Conclusion

ECG abnormalities are common among young populations and more prevalent in nonathletes. Among pupils with major ECG abnormalities 1.6% had a cardiac disease diagnosis. Our results are in line with the data supporting ECG screening in the general young population.
Development of a Testing Station for Empirical Verification of the Algebraic Model of Dry Ice Piston Extrusion
Authors: Górecki Jan
Published: September 2021

Efficient use of resources is a very important consideration for every production process, especially where waste materials are used as raw materials. One example of these kinds of processes is dry ice extrusion. Based on the subject literature, it can be observed that the machines available in the market that are used to compress dry ice are characterized by high working force value. This leads to low efficiency of resource consumption, in regards to both electrical energy and carbon dioxide. This paper presents a proposed design of a test stand used for measuring compression force as a function of piston displacement in the course of the dry ice extrusion. The first part of the article presents the testing methodology and test stand design. The second part presents the results of measurement of compression force as a function of piston displacement with three different die types. The results of the study allowed to establish the difference between the values of the measured limit force and the values calculated with an analytical model. The test stand design and the results presented in this paper are important for further research and development works in the area of efficient extrusion and compaction of dry ice.

Published: September 2021

In the present study, the biochemical composition and shape and dimensional traits of 25 rosehip (Rosa canina) genotypes were investigated. The shape and dimensional traits were determined by image processing technique. Seed-propagated rosehip genotypes belonging to R. canina were collected from the natural flora of Mesudiye (Ordu) and Talas (Kayseri) districts. Antioxidant activity (39.510–72.673 mmol · kg−1), total flavonoids (287.80–1,686.20 mg quercetin equivalent (QE) · kg−1) and total phenolics (38,519.40–79,080.60 mg gallic acid equivalent · kg−1) of the genotypes exhibited large variations. Width (12.2 mm) and thickness (12.5 mm) of fruits averages were found to be close to each other. The genotypes exhibited fruit lengths between 12.0 mm and 29.5 mm. Average projected area at horizontal orientation (179.7 mm2) was greater than the projected area at vertical orientation (120.4 mm2). Sphericity average was calculated as 71.4%. According to principal component (PC) analysis, the most important dimensional traits discriminating genotypes from each other were identified as surface area, geometric mean diameter and volume. In terms of shape attributes, distinctive differences were observed in sphericity, circularity, elongation and surface closure rates (SCR) of the genotypes. According to elliptic Fourier analysis (EFA), genotypes look like a sphere. In terms of shape, there were long, spherical, flat bottomed, pointed bottomed and asymmetric-looking genotypes indicating how environment and genotype affect the fruit shape. The greatest shape variation was transverse contraction and expansion. According to the clustering analysis for shape attributes, rosehip genotypes were classified into six groups. Dendrogram, scatter plots of linear discriminant analysis and paired comparison test results put forth the shape differences of the genotype successfully.
The Synthetic Performances of Teochew
Authors: Luo Zhuosi
Published: September 2021

Huang (2015) characterizes “Modern Chinese as a language of high analyticity at multiple levels” and demonstrates “a ranking of relative analyticity among the three dialects: Cantonese > Mandarin > TSM”. This paper argues that Teochew (cháoshànhuà, 潮汕話), another variety of Min, different from TSM, shows more synthetic performances than Mandarin. Chomsky’s “productivity” criterion (1970) helps distinguish lexical operations from syntactic ones. In this spirit, this paper will illustrate its arguments from two perspectives -- lexical and syntactic operations. When it comes to lexical operations, analyses on both the semantic changes within the same categories and the categorial shifts will be made. Besides, syntactic discussions on emphatic inflection, bare classifier phrases, verb-object order and other variants of V-movements in Teochew will also be demonstrated. All analyses will be put under the theoretical framework of generative grammar with the help of a cartography approach. For analyses at the lexical layer, this paper adopts Si’s 司富珍 (2012, 2017a, 2017b, 2018) XW structure, trying to capture the synthesis performances of the Teochew lexicon. As for syntactic operations, the split-CP hypothesis of Rizzi (1997, 2001, 2004) and Rizzi and Bocci (2015), the CL-to-D hypothesis of Simpson (2005), the light verb approach of Chomsky (1995) and the split-light verb hypothesis of Si 司富珍 (2018) will be used as references. Through comparative studies with Mandarin, Cantonese and other languages like English, this paper will conclude that Teochew is a dialect with higher synthesis compared with Mandarin.

ABSTRACT

Melon fruit which is undergone a minimal process is easy to damage (perishable) with short shelf life.  This study aims to determine the effect of coating aloe vera gel with a mixture of ascorbic acid and potassium sorbate on weight loss, pH, and organoleptic of fresh-cut melons. This study using a completely randomized design (CRD consisted of two treatment factors, namely ascorbic acid (0%, 1.5%, and 3%) and potassium sorbate (0%, 0.2% and 0.4%)). The experiment was replicated three times with a storage temperature of 5 ± 2?C. The results showed that ascorbic acid and potassium sorbate significantly affected the weight loss, pH, and organoleptic values ??of fresh-cut melons. Ascorbic acid and potassium sorbate can inhibit weight loss, maintain organoleptic values ??, and reduce the pH value of fresh-cut melons so that the activity of fungal and mold growth is inhibited. Aloe vera gel with the addition of 3% ascorbic acid and 0.2% potassium sorbate was the treatment that gave the best organoleptic value during storage. This combination can maintain the value of color and texture up to day 14 and maintain aroma until day 10.

Background: COVID-19 is a disease caused by infection of SARS-CoV-2 virus which leads to mortality due to respiratory failure. The progression of COVID-19 is more severe in patients with pre-existence morbidities, including liver disease. Recently, a few studie showed that liver cirrhosis patients with COVID-19 had a higher risk of mortality rather than liver cirrhosis patients without COVID-19 infection. Nevertheless, the study of survival COVID-19 in a patient with underlying liver cirrhosis is still limited. The aim of this study is to evaluate the survival of COVID-19 in adult patients with liver cirrhosisMethod: An observational study in Cipto Mangunkusumo Hospital was conducted. Patients with underlying liver cirrhosis between March 2020-January 2021 with positive confirmation of COVID-19 were enrolled in this study. Liver cirrhosis patients without COVID-19 were enrolled as a comparison. Both liver cirrhosis patients with and without COVID-19 were follow up at the time of hospital admission until 30 days outcome. Kaplan Meier and a log-rank test were conducted to evaluate the comparison of survival rate in liver cirrhosis patients with and without COVID-19. Multivariate Cox Proportional Hazard was conducted to identify the independent risk factors related to survival.Results: There were 22 liver cirrhosis patients with COVID-19 and 116 liver cirrhosis patients included in this study. Presentation of gender and age similar both of them. Predominantly males with average age were 57 years ± 13,60 for cirrhosis with COVID-19 patients and 53 years ± 12,75 for without COVID-19. The survival rate of liver cirrhosis patients with COVID-19 lower than liver cirrhosis patients without COVID-19  (35.8% vs. 67.2%, p-value 0.001). Median survival of liver cirrhosis patients with COVID-19 was 4 days (95% CI: 1-8 days), while median survival of liver cirrhosis patients without COVID-19 couldn’t be reached since the survival rate of this group above 50%. Final model Cox PH showed that liver cirrhosis with COVID-19 (HR: 8.99; CI 95%: 4.55 – 17.80, p-value 0.001) and Child-Pugh class C (HR: 5.61; 95% CI: 2.76 – 11.40, p-value 0.001) were the independent risk factors associated with poor survival.Conclusion: The survival rate of liver cirrhosis patients with COVID-19 lower than liver cirrhosis patients without COVID-19. Liver cirrhosis with COVID-19 and Child-Pugh class C were associated with poor survival.

Gastrointestinal endoscopy is used as a diagnostic and therapeutic tool. Patients receiving antithrombotic agents are at higher risk for bleeding in this procedure. Regarding its thromboembolic versus bleeding risk, physicians should consider to adjust antithrombotic therapy in patients undergoing gastrointestinal endoscopy. Some important factors including the urgency of the procedure, bleeding risk from the procedure and antithrombotic itself, and the risk of thromboembolic events during endoscopy if antithrombotic is to be stopped need to be considered wisely. Based on recommendations of ASGE, ESGE, and BSG, endoscopic procedures were divided based on the level of emergency, namely elective and urgent. In elective endoscopy with high risk of bleeding and thromboembolism, antithrombotic therapy is given in the minimum duration required and then discontinued before the procedure. In elective endoscopy with low risk of bleeding and thromboembolism, antithrombotic can be continued as usual. In urgent endoscopy due to gastrointestinal bleeding, all antithrombotic should be discontinued. Antithrombotic can be restarted within 48 hours after the procedure if no bleeding is evident

Hospital malnutrition is common in Indonesia and other developing countries. In Asia, the prevalence of hospital malnutrition ranges between 27-39%. The causes of malnutrition in hospital care include insufficient food intake and increased catabolic processes due to underlying causes such as metabolic disease, infection, and malignancy. Several studies have demonstrated that malnutrition increases the morbidity and mortality of hospitalized patients, prolongs hospital stay, and delays recovery. Therefore, healthcare providers must recognize malnutrition early by conducting nutritional screening and assessment to prevent worsening of malnutrition and administer the optimal nutritional therapy to patients. Apart from giving a standard diet, high-protein food supplementation in liquid form remains a suitable alternative for patients, especially since it is easily digestible. A high protein diet is associated with a better mortality rate, better weight gain, and improved SGA score in patients.

Background: Coronavirus disease 2019 (COVID-19) is a pandemic that causes various types of symptoms. Diarrhea is a gastrointestinal symptom that is hypothesized to be associated with patient morbidity and mortality. Research on the relationship between diarrhea and the incidence of transaminitis, severity and mortality has never been carried out, so further research is neededMethod: Descriptive-analytic research design with a case-control study approach. Sampling using consecutive sampling on patients in the inpatient installation of dr. Saiful Anwar, Malang. Research data on diarrhea incidence, transaminitis, severity, and mortality were obtained from secondary data on COVID-19 patients. Data were analyzed using chi-square with a significance level p 0.05Results: The incidence of diarrhea in COVID-19 patients with transaminitis was 45.8% and significantly associated (p = 0.025). Diarrhea in COVID-19 patients was associated with severity (p = 0.046) and patient mortality (p = 0.028).Conclusion: There is a relationship between the incidence of diarrhea in COVID-19 patients with trasnsaminitis, severity and mortality

Objective: To evaluate the influence of the type of cement on the fracture resistance of full-contour resin nanoceramic crowns cemented over preparations with knife-edge margins. Methods: A right lower premolar typodont model was prepared with a 1.5-mm axial reduction, a 2.0-mm occlusal reduction, and a knife-edge vertical margin. An anatomical crown was designed from the digital scanning of the preparation using CAD/CAM software. Then, 20 crowns were milled from resin nanoceramic CAD/CAM blocks (Cerasmart270™) as well as a replica of the dental preparation in a cobalt-chrome alloy. The 20 crowns were randomly divided into two groups. Group 1 crowns were cemented with self-adhesive resin cement (G-CEM LinkAce™) and group 2 crowns with resin-modified glass ionomer cement (FujiCEM™ 2). Subsequently, they were subjected to a loading test on an Instron universal testing machine until fracture occurred. The data were statistically analyzed using the parametric Student’s t-test (α=0.05). Results: The type of cement was shown to have a statistically significant effect on the crowns’ fracture resistance (p <0.001). Group 1 presented a mean of 1284.3±340.19 Newtons, much higher than the mean recorded in group 2, of 417.9±106.35 Newtons, with an increase of 207.3% in the fracture resistance after self-adhesive luting. Conclusions: Resin nanoceramic crowns cemented with self-adhesive resin cement showed considerably higher fracture resistance than those cemented with resin-modified glass ionomer cement.

Introduction. Cardiac surgeries using cardiopylmonary bypass (CB) have been successfully performed for more than 60 years, but at present it is necessary to further study the changes in tissue hemodynamics during interventions to minimize possible iatrogenic complications. One of these tissues available for direct observation of the vessels of the microvasculature is the retina. Aim – to study the structural and functional state of the retina in patients who underwent cardiac surgery with the use of CB, and to identify potential factors that negatively affect the retinal blood flow. Materials and methods. The clinical study involved 10 patients (20 eyes). All patients before cardiac surgery using CB and 10–14 days after it underwent visometry, perimetry, non-contact tonometry, biomicroscopy, reverse binocular ophthalmoscopy, fundus photography, optical coherence tomography of the retina of the macular region and optic nerve head with determination of the thickness of the layer of ganglion cell and the layer of nerve fibers. To carry out CB, pharmaco-cold cardioplegia was performed with the Custodiol solution using unified surgical and anesthetic tactics. CB was performed on a device with disposable membrane oxygenators (Strockert, Germany) under normothermic conditions, blood circulation was provided with non-pulsating blood flow with a volumetric flow rate of 2.4–2.8 L/min/m2 at an initial dose of heparin of 300 U/kg. Results. The studies revealed a correlation between changes in the histoarchitectonics of the retina and the level of mean arterial pressure (MAP). So, in 30 % of patients, the appearance of ischemic foci along the vascular arcades was found. In 10 % of patients, a decrease in the thickness of the ganglion layer and the layer of retinal nerve fibers was reported as a result of impaired blood circulation in the vessels supplying the optic nerve. Conclusion. Increase in MAP up to 90 mm Hg and above and fluctuations in its level of more than 20 mm Hg (p<0.05) during cardiac surgery under cardiopulmonary bypass in 67 % of cases is accompanied by transient disturbance of regional blood circulation at the level of vessels of the microvasculature of the retina with the appearance of ischemic foci in the retinal tissue. In this regard, it is necessary to carefully monitor the MAP parameters during the cardiopulmonary bypass to prevent circulatory disorders in various organs and tissues of the body.
The role of soluble leptin receptor in the pathogenesis of coronary heart disease
Authors: Polyakova E. A.
Published: September 2021

Introduction. The participation of soluble leptin receptor (SLR) in the formation of hyperleptinemia and leptin resistance in patients with coronary artery disease (CAD) in combination with obesity is discussed.Aim.Study of the role of SLR in the pathogenesis of ischemic heart disease.Materials and methods.A cohort study of 744 patients was performed: 465 patients with CAD (56 years old, Q1=44; Q3=62), 270 patients without CAD (52 years old, Q1=44; Q3=56). Methods: EchoCG, heart computed tomography, coronary angiography. In the blood serum, the lipids, glucose, creatinine, uric acid, and c-reactive protein were assessed using a highly sensitive method (HF-CRP). Concentrations of SLR, leptin (LN), adiponectin (total and high molecular weight), fatty acid binding protein-4 (FABP-4) tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), serum insulin were determined by enzyme immunoassay.Results.The level of SLR in blood serum in men and women with CAD is lower than in men without CAD (p <0.001). In CAD patients, obesity was associated with a low SLR level in the blood serum and a high free LN index. At a serum SLR concentration of <7.5ng/ml in men with CAD, the incidence of obesity was higher simultaneously with signs of visceral obesity of the heart, the presence of atherosclerotic plaques in the common carotid arteries, high glycaemic levels, insulin, IL-6, and LN in serum, serum LN/adiponectin ratio and a high HOMA-IR index. Diabetes mellitus, visceral obesity, high levels of hs-CRP, TNF-α, FABP-4, serum insulin, and HOMA-IR index were more often detected in women with coronary artery disease with SLR <10.2 ng/ml. In men and women with CAD, there were no differences in SLR concentration depending on the extent of coronary atherosclerosis.Conclusion.An increase in the free LN index indicates the disruption of connections in the leptin-receptor system and reflects the mechanisms of compensation for overcoming the resistance of peripheral tissues to leptin, which is confirmed by a noticeable negative relationship between the levels of SLR and leptin in the serum of men with coronary artery disease. A low concentration of SLR in patients with CAD is associated with obesity, pro-atherogenic and pro-inflammatory markers of cardiovascular diseases.

Osteoarthritis is a common disease of the musculoskeletal system, the cause of pain, loss of joint function and, as a consequence, a factor in the disability of the population. The treatment strategy for patients with gonarthrosis is not fully defined, especially in patients with stage 1–2. One of the treatment options for such patients is transcatheter embolization of the hypervascular network of the popliteal arteries. The article presents a series of clinical cases of embolization of the popliteal artery branches. Retrograde percutaneous puncture and catheterization of the target femoral artery were performed under local anesthesia. Then, selective angiography of the popliteal artery was performed to identify the hypervascular vasculature of the knee joint. After revealing the target artery along the interventional guidewire, selective catheterization of the artery of the hypervascular vascular network was performed using a microcatheter. Transcatheter arterial embolization of the hypervascular vascular network in osteoarthritis of various origins and localization can be successfully applied as an alternative treatment if conservative therapy is ineffective and if there are contraindications to surgical treatment. It should be noted that further randomized multicenter studies and meta-analyzes are needed to introduce this treatment method into everyday clinical practice.
