Abstract
Objective: Twitter data have been increasingly used to address health-related issues. However, little is known about their potential for understanding public opinions and sentiments of the current COVID-19 pandemic. The present study explores public opinion and sentiments about the COVID-19 pandemic using Tweets from 3 popular Coronavirus-related hashtags (#COVID19, #Coronavirus, #SARSCoV2).Results: Of the 39,726 Tweets analysed, we found that over 60% of words used within Tweets in all hashtags (#COVID19, 63.9%; #Coronavirus: 65.6%; #SARSCoV2: 63.5%) conveyed a negative mood towards the pandemic. Our results also showed similar trends in Tweet volume in #COVID19 and #SARSCoV2, with a spike in the number of Tweets on the 3rd and 6th of April 2020. Further exploration of Tweets in both hashtags revealed similar Twitter discussions related to topics on “Hydroxychloroquine” and “Hospitalisations of the British Prime minister” and “ the attainment of 1 million cases of coronavirus globally”.The findings of this exploratory study indicate that there is potential for using data generated from Twitter to understand general public opinion and sentiments towards the COVID-19 pandemic. However, caution is needed due to several limitations in this study. It is also important for future studies to explore the context around Tweets.

Abstract
Background Emerging COVID-19 pandemic caused extensive lockdowns in a number of countries, but yet unknown number of cases positive to SARS-CoV-2 escapes surveillance systems. Methods Mothers participating in an Italian NINFEA birth cohort were invited to complete an online questionnaire on COVID-19-like symptoms in the household. We estimated the population prevalence of COVID-19-like symptoms in children and adults, assessed their geographical correlation with the cumulative number of COVID-19 cases by province, analysed their clustering within families, and estimated their sensitivity, positive (PPV) and negative predictive values (NPV) for COVID-19 diagnosis in individuals tested for SARS-CoV-2.Results Information was collected on 3184 households, 6133 adults, and 5751 children. There was a strong geographical correlation between the population cumulative incidence of COVID-19 and the prevalence of muscle pain, fatigue, low-grade fever, and breathing difficulties in adults (Spearman’s rho ≥0.70). Having at least one family member with a COVID-19 diagnosis, compared with none tested for SARS-CoV-2, was associated with an increased prevalence ratio of almost all COVID-19-like symptoms in adults, and only of low-grade fever (37-37.5oC; prevalence ratio 5.27; 95% confidence intervals: 2.37 to 11.74) and anosmia/dysgeusia in children. Among adults with COVID-19, fatigue, muscle pain, and fever had a sensitivity ≥70%. In individuals tested for SARS-CoV-2, with a 16.6% prevalence of COVID-19, breathing difficulties and nausea/vomiting had the highest PPVs, with point estimates close to 60%, and with NPVs close to 90%. Among tested Piedmont residents, with a COVID-19 prevalence of 18.5%, breathing difficulties and anosmia/disguesia reached PPVs above 80%.Conclusion Geographical prevalence of COVID-19-like symptoms in adults may inform on local disease clusters, while certain symptoms in family members of confirmed COVID-19 cases could help identification of the intra-familial spread of the virus and its further propagation in the community. Low-grade fever is frequent in children with at least one household member with COVID-19 and possibly indicates child infection.
Sclerotherapy: step by step – liquid sclerotherapy
Authors: Bogachev V. Yu. , Lobanov V. N. 
Published: June 2020

Classic sclerotherapy using drugs in the native (liquid) state is almost the oldest method of minimally invasive treatment of various forms of varicose veins of lower extremities and not only. Despite more than 300 years of development of the sclerotherapy methodology, enormous international experience and almost thorough study of its mechanisms, the development of new sclerosing drugs and technologies of their delivery to the lumen of the target vein continues. Measures aimed at reducing the frequency of undesirable side effects after sclerotherapy and improving the quality of life of patients during treatment and after its completion are discussed separately. Currently, there are several guidelines that regulate phlebosclerosing treatment in various clinical situations in terms of evidence-based medicine. This publication provides a brief historical background on the formation of sclerotherapy technology, presents basic principles for liquid sclerotherapy based on the analysis of international and Russian recommendations for the treatment of chronic venous diseases. Indications, contraindications and the basic methods of carrying out sclerotherapy with the use of officinal, registered in the Russian Federation phlebosclerosing detergent agents are presented, their actual physical and chemical properties, similarities and distinctions, and also optimal concentrations and doses are discussed. The classic sclerotherapy technique which has become known as “empty vein technique” is described in detail and illustrated.In addition, current clinical examples demonstrating successful use of compression sclerotherapy are presented. Again, the authors conclude that liquid sclerotherapy with the use of modern phlebosclerosing agents such as lauromacrogol 400 and sodium tetradecyl sulfate, performed according to the classical “empty vein” technology, demonstrates high efficiency and safety regarding large varicose veins of various localizations.
Review of the plethysmographic methods for studying hemodynamic disorders in patients with chronic lower extremites venous diseases
Authors: Sannikov A. B. , Emelyanenko V. M. , Drozdova I. V. 
Published: June 2020

Plethysmography as a method for studying peripheral circulatory system was first proposed by wletney in 1953. In Russia, the first most significant research studies on the feasibility of plethysmography in studying peripheral blood flow and circulatory physiology taken together were conducted at the St. Petersburg Pavlov Institute of Physiology in 1961. From this time onwards, the possibilities of plethysmography as a non-invasive objective method for the diagnosis of hemodynamic disorders, particularly in arterial pathology, were studied intensively. These parameters were not determined for the venous blood flow, but in 1980s the authors were able to establish plethysmographic criteria not only for various forms of venous pathology, but also for degrees of chronic venous insufficiency using a device significantly improved by V.N. Pavlov and V.E. Maslov.The purpose of this publication is to analyze the literature data on the use of aerial plethysmography and photoplethysmography in the study of hemodynamic disorders in patients with chronic diseases of the veins of the lower extremities. At present, in order to assess the venous blood flow in condition of air plethysmography, indicators of functional venous volume (VV), maximum venous outflow (MVO), venous filling index (VFI), evacuation volume (EV) and residual volume (RV), as well as an integral indicator – residual volume fraction (RVF) are determined in the world. A venous reflux test (VRT) is performed as part of photoplethysmography. The data published today show the high statistical reliability of the comparative analysis and the great scientific significance of the research. According to many foreign authors the use of plethysmographic methods of diagnosis allow to assess violations of venous blood flow in patients with chronic venous diseases of various clinical classes according to CEAP more precisely and to give a global assessment of disorders of the venous outflow from thrombotic occlusion of segmental to hypervolemia in patients with varicose veins in different forms of manifestations of chronic venous insufficiency. The analysis of the literature data allows to make a conclusion about the prospects of further research using these non-invasive methods of evaluation of venous blood flow in the lower extremities.
Foreign Brand Admiration Among Young Consumers in Indonesia
Authors: Sulhaini  , Sagir Junaidi , Sulaimiah  
Published: June 2020

This study extends the theoretical understanding of the positive and negative emotions of consumers towards foreign vs local brands by providing conceptualisation and measurement of foreign brand admiration and passive brand hate towards local brands. The study incorporates hedonic value dominance and home country image, which is the image of a consumer’s own country. The results show that young consumers in a developing country are both passive brand haters towards local brands and foreign brand admirers. When they possess an inferior image of their home country, they show admiration towards foreign brands. The positive emotion is however mainly influenced by hedonic value dominance, which also have a great contribution to passive brand hate toward local brands. As they have strong negative emotion, they tend to admire foreign brands that offer more hedonic values. In comparison to the negative emotion, the positive emotion indeed has a much stronger contribution toward willingness to pay more for foreign brands. The paper provides useful managerial implications for foreign brand and local brand owners to compete in the country’s marketplace.

Authors: Simangunsong Eliot , Handoko Rudy 
Published: June 2020

The rise of social media in today’s digital era is considered important because it helps people communicate and share information online. It is not surprising that ease of sharing information and communicating through social media has an impact on increasing many online activities, including business activities. This phenomenon is an inspiration that researchers can use to uncover the role of social media in Indonesia for business activities by knowing the factors that can influence a social media follower or fans into actual buyers. By surveying users of social media, 546 responses were collected from social media entrepreneurs and social media buyers. The data analysis showed there is enough evidence that social media is being used for business. The frequency of social media usage has strong links to users to use to buy products or do business in that venue. Young people, such as college students, tend to use social media for business more than those with higher levels of education who may already have permanent jobs. Multiple regression analyses have resulted in a proposed model of social media use for business and offers five major factors that influence satisfaction and performance when doing business on social media.

Authors: Hosny Samar , Sahyon Heba , Youssef Magdy , Negm Amr 
Published: June 2020

Background:
Despite significant advances in therapeutic interventions, liver cancer is the leading
cause of cancer mortality in the world. Potential phytochemicals have shown to be promising agents against
many life-threatening diseases because of their low toxicity and potential effectiveness.

Objective:
The current study aims to conduct an in vitro investigation of the anticancer activity of Apricot Extract
(AE) and Amygdalin Containing Fraction (ACF), additionally studying their therapeutic effects on DMBAinduced
liver carcinogenesis mice model to highlight their related biochemical and molecular mechanisms.

Methods and Results:
Amygdalin was isolated from the seeds of P. armeniaca L. Male mice received AE or
ACF, DMBA, DMBA+AE, DMBA+ACF, and vehicles. The oxidative stress and antioxidant markers, cell proliferation
by flow cytometric analysis of Proliferating Cell Nuclear Antigen (PCNA) expression, angiogenesis
marker (VEGF), inflammatory marker (TNF-α), apoptotic, anti-apoptotic and autophagy genes expression
(caspase-3, Bcl-2, and Beclin-1) were investigated. AE and ACF were found to stimulate the apoptotic process
by up-regulating caspase-3 expression and down-regulating Bcl-2 expression. They also reduced VEGF and
PCNA levels and increased the antioxidant defense system. Moreover, AE and ACF treatments also inhibited
HepG2 and EAC cell proliferation and up-regulated Beclin-1 expression.

Conclusion:
This study provides evidence that, in DMBA-induced hepatocarcinogenesis, the key proteins involved
in the proliferation, angiogenesis, autophagy, and apoptosis are feasible molecular targets for hepatotherapeutic
potential using AE and ACF.

Applying a Human-Centered Design to Develop a Patient Prioritization Tool for a Pediatric Emergency Department: Detailed Case Study of First Iterations
Authors: Schiro Jessica , Pelayo Sylvia , Martinot Alain , Dubos François , Beuscart-Zéphir Marie-Catherine , Marcilly Romaric 
Published: June 2020

Background
Overcrowding in the emergency departments has become an increasingly significant problem. Patient triage strategies are acknowledged to help clinicians manage patient flow and reduce patients’ waiting time. However, electronic patient triage systems are not developed so that they comply with clinicians’ workflow.

Objective
This case study presents the development of a patient prioritization tool (PPT) and of the related patient prioritization algorithm (PPA) for a pediatric emergency department (PED), relying on a human-centered design process.

Methods
We followed a human-centered design process, wherein we (1) performed a work system analysis through observations and interviews in an academic hospital’s PED; (2) deduced design specifications; (3) designed a mock PPT and the related PPA; and (4) performed user testing to assess the intuitiveness of the icons, the effectiveness in communicating patient priority, the fit between the prioritization model implemented and the participants’ prioritization rules, and the participants’ satisfaction.

Results
The workflow analysis identified that the PPT interface should meet the needs of physicians and nurses, represent the stages of patient care, and contain patient information such as waiting time, test status (eg, prescribed, in progress), age, and a suggestion for prioritization. The mock-up developed gives the status of patients progressing through the PED; a strip represents the patient and the patient’s characteristics, including a delay indicator that compares the patient’s waiting time to the average waiting time of patients with a comparable reason for emergency. User tests revealed issues with icon intuitiveness, information gaps, and possible refinements in the prioritization algorithm.

Conclusions
The results of the user tests have led to modifications to improve the usability and usefulness of the PPT and its PPA. We discuss the value of integrating human factors into the design process for a PPT for PED. The PPT/PPA has been developed and installed in Lille University Hospital's PED. Studies are carried out to evaluate the use and impact of this tool on clinicians’ situation awareness and prioritization-related cognitive load, prioritization of patients, waiting time, and patients’ experience.
