Abstract Background: Three-dimensional (3D) technologies have numerous medical applications and have gained a lot of interest in medical world. After the advent of three-dimensional printing technology, and especially in last decade, orthopedic surgeons began to apply this innovative technology in almost all areas of orthopedic traumatic surgery. Objective: The aim of this paper is to give an overview of 3D technologies current usage in orthopedic surgery for patient specific applications. Methods: Two major databases PubMed and Web of Science were explored for content description and applications of 3D technologies in orthopedic surgery. It was considered papers presenting controlled studies and series of cases that include descriptions of 3D technologies compatible with applications to human medical purposes. Results: First it is presented the available three-dimensional technologies that can be used in orthopedic surgery as well as methods of integration in order to achieve the desired medical application for patient specific orthopedics. Technology starts with medical images acquisition, followed by design, numerical simulation, and printing. Then it is described the state of the art clinical applications of 3D technologies in orthopedics, by selecting the latest reported articles in medical literature. It is focused on preoperative visualization and planning, trauma, injuries, elective orthopedic surgery, guides and customized surgical instrumentation, implants, orthopedic fixators, orthoses and prostheses. Conclusion: The new 3D digital technologies are revolutionizing orthopedic clinical practices. The vast potential of 3D technologies is increasingly used in clinical practice. These technologies provide useful tools for clinical environment: accurate preoperative planning for cases of complex trauma and elective cases, personalized surgical instruments and personalized implants. There is a need to further explore the vast potential of 3D technologies in many other areas of orthopedics and to accommodate healthcare professionals with these technologies, as well as to study their effectiveness compared to conventional methods.

Heart involvement in Cardiac Amyloidosis (CA) results in a worsening of the prognosis in almost all patients with both light-chain (AL) and transthyretin amyloidosis (ATTR). The mainstream CA is a restrictive cardiomyopathy with hypertrophic phenotype at cardiac imaging that clinically leads to heart failure with preserved ejection fraction (HFpEF). An early diagnosis is essential to reduce cardiac damage and to improve the prognosis. Many therapies are available, but most of them have late benefits to cardiac function; for this reason, novel therapies are going to come soon.

Inclusion And Diversity

This article answers the question, "is the use of the words inclusion and diversity an expression of institutional racism?" In almost all Western countries, immigrants and refugees barely penetrate all levels of organizations. Immigrants and refugees are mostly found in the lower echelons of an organization. To put it irreverently: the dirtier and heavier the work, the more immigrants and refugees are found there. Also in governments and parliaments immigrants (not even the second, third and fourth generation) are hardly to be found. So the good example is lacking. This article starts with an etymological examination of inclusion and diversity. The outcome is briefly summarized: " we want YOU -immigrant and/or refugee- to come and work for us because we are not allowed to hire only natives". That human rights are violated in this way does not seem to be an issue. Furthermore, we argue that it is precisely the words inclusion and diversity that prevent the recruitment of immigrants and refugees, as well as expats who have lost their jobs, from being given a high priority. This article proposes two new terms as just and equitable alternatives to inclusion and diversity. First, the statistical concept of representative and second, in support of the static concept of representative, the concept of wanting to be a mirror of the population from the neighbourhood, city or country that the leadership of the company or institution believes should be part of the work organization and from low to high. To further support this argument to replace the concepts of inclusion and diversity, Moscovici's (2001) concept of social representation is used. This article also looks at existing toolboxes and toolkits that Western countries have developed to ensure that organizations of governments, institutions independent of government, and businesses are representative of neighbourhoods, cities, and countries. Companies in particular are committed to this because they understand better than anyone that their paying customers are also immigrants, refugees and expats. This knowledge of toolboxes and toolkits was helpful in developing a guideline for organizations of governments, institutions independent of government and companies and therefore also parliaments and governments. The guideline also addresses violations of this guideline. To address violations, it proposes a self-learning model for teams in organizations that is also consistent with enforcing the Working Conditions Act in Western countries.

The unavoidable suffering is an outstanding theme which has its impact to almost all literary texts. Typically, unavoidable suffering is the supreme touchstone in life and literature. Poets used its presence incessantly. They are always conscious of its inevitability. Investigation of this theme gives the reader a panoramic view of vital issues that are unusually linked to some extent with suffering; such as religion, God, nature, love and immortality. In the poems discussed in this study, unavoidable suffering reflects the effect of modern psychology has had upon both literature and literary criticism. The main reflection of suffering which is implied in the characters presented reveal the very contradictions, absurdities and complexities of our life. The poets and novelists chosen in this paper portray suffering, as “an abstract force, in an attempt to come to terms with it as well as to fathom it.” (Gurra, 2019, p.5) In the inexorable quest to comprehend it, poets do not offer a final view of suffering because it remains for them the great unknown mystery. This paper, however, is an attempt to meticulously examine and critically analyze the images of suffering in minor characters presented in selected poems. The selected poems are of Robinson Jeffers, Allen Ginsberg, and Maya Angelou. The characters selected from different novels are minor ones. Characters like: Roger Chiilingworth from The Scarlet Letter (1850), Walter Morel from Sons and Lovers (1913), Zeena Frome from Ethan Frome (1911), and Rezia Warren Smith from Mrs. Dalloway (1925). Different kinds of suffering are disscussed in order to gain a better understanding of the writers’ perception of unavoidable suffering as well as to understand the western philosophy of it.

This case highlights Indian Tobacco Corporation (ITC)’s journey from being a pure leaf tobacco selling company to a reputed conglomerate with popular brands in diversified areas. ITC’s corporate social responsibility (CSR) and sustainability activities taking a turning point with the company taking an immense interest in integrating societal problems in its company’s policies and strategies. These transformations can be seen in almost all the business divisions of ITC. Mangaldeep division, an incense stick division is not an exception to this change. However, the authors are trying to analyze the activities of ITC–Mangaldeep Business unit from different perspectives such as CSR, sustainability and shared value initiatives. Considering the resource constraint and the demand to meet the societal needs, it will be quite interesting to know how both these two challenges are met by a conglomerate like ITC simultaneously in the days to come. The case uses both primary and secondary sources of information to develop this teaching case.
