    AbstractObjectives:Coronavirus disease (COVID-19) has been identified as an acute respiratory illness leading to severe acute respiratory distress syndrome. As the disease spread, demands on health care systems increased, specifically the need to expand hospital capacity. Alternative care hospitals (ACHs) have been used to mitigate these issues; however, establishing an ACH has many challenges. The goal of this session was to perform systems testing, using a simulation-based evaluation to identify areas in need of improvement.Methods:Four simulation cases were designed to depict common and high acuity situations encountered in the ACH, using a high technology simulator and standardized patient. A multidisciplinary observer group was given debriefing forms listing the objectives, critical actions, and specific areas to focus their attention. These forms were compiled for data collection.Results:Logistical, operational, and patient safety issues were identified during the simulation and compiled into a simulation event report. Proposed solutions and protocol changes were made in response to the identified issues.Conclusion:Simulation was successfully used for systems testing, supporting efforts to maximize patient care and provider safety in a rapidly developed ACH. The simulation event report identified operational deficiencies and safety concerns directly resulting in equipment modifications and protocol changes.

    Today, tremendous attention has been devoted to a new coronavirus, SARS-CoV-2 (2019-nCoV), due to severe effects on the global public in all over the world. Rapid and accurate diagnosis of 2019-nCoV are important for early treatment and cutting off epidemic transmission. In this regard, laboratory detection protocols, such as polymerase chain reaction (PCR) and computed tomography (CT) examination, have been utilized broadly for 2019-nCoV detection. Recently, nano-based methods for 2019-nCoV diagnoses are rapidly expanding and declaring comparable results with PCR and CT. In this review, recent advances in nano-based techniques have been highlighted and compared briefly with PCR and CT as well-known methods for 2019-nCoV detection.

    Cultural tightness–looseness, one of the cultural dimensions that play an essential role in organizational development, is changing the perception of psychology and behavior in organizations. This study conducted a paired questionnaire survey of leaders and their employees from five Chinese companies over three periods during the COVID-19 pandemic. The results found that organizational cultural tightness was more influenced by transformational leadership. Different from previous findings, in the context of the Chinese epidemic, organizational cultural tightness positively predicted employees’ work engagement with the moderating effect of transformational leadership. Team-member exchange also mediated employees’ work engagement, which had a facilitative effect on employees’ work engagement. In future research, the contingent effects of other leadership styles and organizational cultural tightness will be explored to reveal the different mechanisms of action on employees’ work engagement.

    Background: COVID-19 is a respiratory disease transmitted through respiratory droplets with a high transmission rate. There's still no effective and approved antiretroviral treatment or vaccine, thus, preventive measures are the main key to contain this pandemic. Portugal is now in phase 3.2 of the mitigation of COVID-19, being imperative to understand the health literacy of our country and how to prevent the lack of information, through community empowerment. Material and methods: A cross-sectional study with a cohort from a primary care facility was conducted. We collected demographic and epidemiological data and carried out a questionnaire by phone call. Descriptive statistics and nonparametric tests were used to assess associations between the independent variables and the level of health literacy. The level of significance was set at p<0.05. Results: Our cohort includes 222 subjects (median age: 62 years old), mostly females (131), undergraduate (193) and with at least one risk factor for COVID-19 (144). Globally, younger individuals, females, graduates and the Non-Risk Group appear to have higher levels of health literacy, with some exceptions to this pattern. Conclusions: We observe a well-informed population. However, being a pandemic situation, we intend to identify and correct outliers/misconceptions. This work allows a perspective of the current state/pattern of health literacy as well as its possible predictors. Furthermore, this study makes aware of how relevant the specific communication approaches are. Further studies to understand the predictors of health literacy are necessary. Key-Words: COVID-19, pandemic, SARS-CoV2, Portugal, Health literacy.

    Online psikoterapi ve danışmanlık özellikle çağımız gelişen dijital dünyasında interneti kullanabilme özelliği olan, telefon, bilgisayar ve benzeri iletişim araçları ile uygulanan bir terapi çeşididir. Dijital dünyanın ve internetin kullanımındaki hızlı artış ile orantılı olarak son dönemlerde popüler olan online terapiler klasik psikoterapi uygulamalarına göre maliyetinin daha uygun olması, gizliliğe önem veren hasta ve danışanlar açısından avantajları, ev ya da seyahatte olunması durumlarında dahi zaman ve mekân açısından getirdiği avantajlar gibi nedenlerle tercih edilmekte ve her geçen gün kullanımı ve çeşitliliği artmaktadır. Bu makalede online terapi hizmetlerinin tanımı, tarihçesi, hangi terapi ve danışmanlık hizmetlerini içerdiği, dünyada ve ülkemizdeki kullanımı, dünya ve ülkemiz ölçeğinde etik ilkeleri, standartları, avantaj ve dezavantajları açısından genel bir bakışın sağlanması amaçlanmıştır. Aynı zamanda uzun yıllardır geleneksel olarak yüz yüze uygulanan klasik psikoterapi ve psikolojik yardım uygulamalarında var olan mesleki standartların ve etik ilkelerin online psikoterapi ve danışmanlık alanına güncel olarak uyarlanmasında önerilerde bulunmak amaçlanmıştır. Günümüzde özellikle bireysel kullanımı artan çağdaş teknolojilerle birlikte, ihtiyaç duyulan ve Covid-19 pandemi döneminde önemi daha da artan online terapi hizmetlerinin ülkemizde yasal mevzuatının, etik ilke ve standartlarının daha fazla netleştirilmesi gerekmektedir. Online psychotherapy and counseling, in our rapidly developing digital world, refer to the types of therapies which can use internet, and which are applied via smartphones, computers and similar communication gadgets. In addition to the fact that online therapies have gained the popularity with the increasing usage of the digital world and the internet, they also have some advantages against the classic psychotherapy such as lower cost, higher privacy and conveniences about time and place that is provided even from homes or vacations; therefore, they are widely preferred and they grow in both application and diversity. In this article, it is aimed to provide a general information about the online therapies’ definition, history, types and services, application and ethical principles within the Turkey and the World, standards, advantages and disadvantages. Therewithal, this article's another point is to make recommendations about the current adaptations of vocational standards and ethical principles from the classic psychotherapy and consultancy which have been applied face-to-face for a long time to online psychotherapy and consultancy. Today, especially in the Turkey where the demand for online therapy and the usage of internet and technology systems are increasing, even more during the Covid-19 pandemic, the legal regulations, ethical principles and standards of the online therapy services need to be further clarified.

    Въведение: Заболяването от COVID-19 води до мултиорганно засягане, ендотелно възпаление и микро- и макроваскулит, при които може да настъпи тромбоза в малките съдове, в съдове в различни органи, както и в сърдечните кухини. Някои от усложненията може да персистират, което се наблюдава в нашия клиничен случай и това го прави особено интересен. Клиничен случай: Представяме 73-годишен пациент с известно перманентно предсърдно мъждене и прояви на хронична сърдечна недостатъчност, поплитеална флеботромбоза и операция на лява тазобедрена става. 53 дни след доказан положителен тест за COVID-19 поради оплаквания от фебрилитет и кашлица на фона на негативен ваксинационен статус пациентът е хоспитализиран с клиника на лека дихателна недостатъчност и кардиогенен шок. От направените лабораторни изследвания се установиха повишени маркери за възпаление. ЕКГ показа тахиаритмия (170 уд./min) и предсърдно мъждене. ЕхоКГ разкри наличието на ДК-систолна дисфункция, пулмонална хипертония и масивен тромб в дясното предсърдие. С помощта на Доплер се доказа феморопоплитеална тромбоза вдясно, а CT-пулмоангиографията показа данни за масивна двустранна БТЕ. Взе се решение за провеждане на системна фибринолиза, която се понесе без усложнения. По време на хоспитализацията не се установи наличие на неопластично заболяване. Заключение: Този клиничен случай потвърждава високия риск от тромбози вследствие на Ковид инфекция (флеботромбоза, предсърдна тромбоза и масивна двустранна БТЕ) без оптимална антикоагулантна терапия и при прием на антиагрегант около 2 месеца след началото на симптомите. Background: The coronavirus disease (COVID-19 disease) leads to multiple organ disease, inflammation of the endothelium, and micro- or macrovasculitis that may result in thrombosis of the small vessels, and thrombosis of vessels in various organs, as well as intracardiac thrombosis. Some of the complications may be long-lasting, as in our case, which makes it particularly interesting to discuss. Case report: We present a 73-year-old male patient with a history of permanent atrial fibrillation and chronic heart failure (II NYHA class), popliteal phlebothrombosis, and surgery of the left hip joint. 53 days after a positive rapid test for Covid 19 performed because of fever and coughing, the patient, who is not vaccinated for Covid 19, was hospitalised at our Department with clinical signs of mild respiratory failure and cardiogenic shock. The laboratory tests revealed elevated markers of inflammation. The ECG showed tachyarrhythmia (170/min) and atrial fibrillation. The EchoCG displayed evidence of right systolic dysfunction, pulmonary hypertension, and a massive thrombus in the right atrium. The Doppler ultrasonography revealed the presence of right femoropopliteal thrombosis, while the CT-pulmoangiography showed evidence of massive bilateral PE. A decision was made to perform systemic fibrinolysis, which the patient tolerated without complications. During the hospitalisation, the examinations revealed no evidence of an oncological disease. Conclusion: The reported clinical case confirms the high risk of thrombosis due to a COVID-19 infection, such as phlebothrombosis, atrial thrombosis, and massive bilateral PE, in the absence of optimal anticoagulant therapy and against the backdrop of the administration of antiplatelet therapy roughly 2 months after the onset of the COVID-19 symptoms.
