Background-: Left ventricular outflow tract obstruction is an independent predictor of adverse outcome in hypertrophic cardiomyopathy (HCM). The classical quantification of intraventricular obstruction is performed in resting conditions in supine position, but this assessment does not reflect what happens in HCM patients (pts) in their daily activities, neither during effort nor during orthostatic recovery.

Background: The systolic pulmonary artery pressure (PAPs) can be accurately estimated, noninvasively, using continuous-wave Doppler (CWD) ultrasound measurement of the peak velocity of a tricuspid regurgitant (TR) jet.

RESUMEN: La propuesta del articulo es analizar la diversidad sexual y la homofobia en el medio educativo portugués, a través del estudio comparado resultante del proyecto "Sexualidades Juventudes e Gravidez Adolescente a Noroeste de Portugal" con los datos del informe sobre homofobia y transfobia del Observatorio de Educación LGBT. La metodología utilizada fue estudio cualitativo en el primero y cuantitativo en el segundo. De ambos trabajos se llega a la conclusión que la mayoría de los jóvenes muestra una actitud desfavorable hacia las personas LGBT, desinformación acerca de la diversidad sexual, acompañada por una alta difusión de mitos y estereotipos, los cuales resultan en actitudes homofóbicas y sexistas. La escuela sigue siendo uno de los lugares privilegiados en la construcción de la identidad, pero que no está preparada para enfrentarse a la problemática de la diversidad sexual educar en el respeto a la diversidad afectivo-sexual es tarea de todas y todos.

In the increasingly competitive hotel environment, decision-makers must consider the risks and benefits of remaining independent or affiliating with a brand or consortium. This research sought to understand the level of importance associated with a set of motivating factors considered by Portuguese four- and five-hoteliers as it relates to remaining independent or affiliating. The study results suggest that independent hoteliers rank control over decision making and shorter decision making as most important in remaining independent, and increased sales and more aggressive marketing as most important in the decision to affiliate. Affiliated hoteliers rank shorter decision making and absence of fees as most important in remaining independent, and increased sales, brand value, and more aggressive marketing as most important in the decision to affiliate. Interestingly, independence and freedom were considered less important in the decision to remain independent, by all respondents. We apply Hofstede’s cultural dimensions theory to explain some of the key findings.

A 70-year-old man developed drug refractory acute pulmonary oedema secondary to acute severe mitral regurgitation (MR) immediately after implantation of a dual-chamber pacemaker for complete heart block. Clinical improvement occurred after allowing the patient to resume his native rhythm. A new lead was positioned within the right ventricular outflow tract (RVOT). The echocardiogram during pacing at RVOT showed minimal MR.

Purpose This paper aims to better understand community of practice (CoP)’s dynamics with a focus on the hotel sector and perceived benefits to members and business performance. Design/methodology/approach This is a case study research focusing on a successful experience within a CoP found in the hotel sector. The study reports in detail how a CoP was created and how it evolved to a digital platform to give birth to a fully co-designed tourism product. It analyzes this CoP’s social dynamics, processes of communication and interaction, as well as digital evolution. To collect rich data, method triangulation was applied by mixing quantitative and qualitative analyses. Findings The community is highly participated and valued because it is perceived as a dynamic system contributing to rapid information exchange and diffusion, efficient context for knowledge transfer and individual responsiveness to daily professional activities and challenges. The reasons why members perceive Amigas do Trade as a distinctive community include shared values and attitudes; professional area and position; and group composition. The majority of members acknowledged that belonging to this CoP has helped in making an informed decision with impact on business practice. The sub-theme more intensely participated and discussed concentrated on human resources issues. Research limitations/implications A case study brings useful insights into the understanding of CoP members’ behaviour; however, findings are not generalizable to other communities. Practical implications This study contributes in several ways to business practice and management. Hotel businesses pertain to a sector in which CoPs easily thrive. This seems to happen because businesses in the tourism and hospitality industry are highly dependent on networks, people, communication channels and technologies. Engagement with technological platforms is stimulated because of the unproblematic integration of these digital platforms into other technologies members already use in their daily work and life. Moreover, digital platforms are not expensive and potentially increase motivation levels within CoP, and consequently in companies. This example inspires the use of digital platforms to exchange knowledge in other CoPs in the hotel sector. Social implications CoPs are contexts of good interaction within a group of people by nurturing a good value system (comprehending trust, cohesion and good communication climate). Thus, a non-hierarchical and non-biased approach to CoP by managers could be accomplished by fostering an organizational culture based on joint innovation, coopetition and open communication principles. Expectedly, in this respect, intensive use of digital technologies in the business arena will keep playing a key role. Originality/value To the best of the authors’ knowledge, this is the first study on CoP applied to the hotel sector. Additionally, it is also the first time a CoP composed only by women working in the hotel sector was analyzed. One other element of novelty links to the fact that a CoP with physical and virtual dimensions was studied, introducing the use of digital platforms to the analysis of CoP dynamics.

Over the last months, since being declared as a pandemic by the World Health Organization (WHO) on March 11, 2020, the impacts on the political, social, and economic system, with no precedents, caused a global crisis to which the world is trying to respond in order to recover from a crisis that remains unpredictable due to the high contagiousness characteristic of the virus [1].According to WHO, the virus has spread to 115 countries, and almost 4,300 people have died in two months and on March 11, 2020, COVID-19 is called a pandemic disease [2]. Humanity was suspended for a couple of months, in the socalled lockdown. People stayed at home and the economy went through one of the most complicated periods ever. The tourism sector has stopped its activities due to business and leisure travel cancellations. Hotels closed doors, for the first time, since they had open to the public. Planes, instead of filling the skies, filled the airport parks. Tourism professionals start to work from home using technologies to continue their activities. Tourism is very rewardable to crises, like diseases, financial breakdowns, or wars in complex times. It is one of the activities that suffer the most of the direct and indirect impacts of these crises. In 2020, the world met a brand-new pandemic in the twenty-first century [3], so now it is important to S. Almeida ( )
