RESUMO
The sharp rise in the number of predominantly natal female adolescents experiencing gender dysphoria and seeking treatment in specialized clinics has sparked a contentious and polarized debate among both the scientific community and the public sphere. Few explanations have been offered for these recent developments. One proposal that has generated considerable attention is the notion of "rapid-onset" gender dysphoria, which is assumed to apply to a subset of adolescents and young adults. First introduced by Lisa Littman in a 2018 study of parental reports, it describes a subset of youth, primarily natal females, with no childhood indicators of gender dysphoria but with a sudden emergence of gender dysphoria symptoms during puberty or after its completion. For them, identifying as transgender is assumed to serve as a maladaptive coping mechanism for underlying mental health issues and is linked to social influences from peer groups and through social media. The purpose of this article is to analyze this theory and its associated hypotheses against the existing evidence base and to discuss its potential implications for future research and the advancement of treatment paradigms.
RESUMO
In the 1960s, the demonstration of interference effects using two laser-beams raised the question: can two photons interfere? Its plausibility contested Dirac's dictum, "Interference between two different photons never occurs". Disagreements about this conflict led to a controversy. This paper will chart the controversy's contour and show that it evolved over two phases. Subsequently, I investigate the reasons for its perpetuation. The controversy was initiated and fuelled by several misinterpretations of the dictum. I also argue that Dirac's dictum is not applicable to two photon interference as they belong to different contexts of interference. Recognising this resolves the controversy.

OBJECTIVES: This study investigated levels of trust and attributions of blame in connection with a cervical screening programme following a controversy related to the programme's audit, incorporating an experimental test of the effectiveness of new information materials. DESIGN: We compared responses in Ireland (N = 872) to equivalent responses in Scotland (N = 400). Participants in Ireland were randomly assigned to either a treatment group that received the information materials or a control group that did not. Participants then responded to questions about their trust in cervical screening and to whom they would attribute blame in a range of scenarios describing women diagnosed with cervical cancer between screening rounds. RESULTS: Results showed that the control group in Ireland had lower trust and attributed higher blame towards screening services than participants in Scotland. However, exposure to information materials in the treatment group improved trust and reduced blame. CONCLUSIONS: The findings suggest that public controversies influence perceptions of screening programmes and underscore the importance of transparent, choice-based communication in mitigating these effects. The findings have valuable implications for screening services worldwide as all screening programmes will have associated false negative and false positive results.

The role of vitamin D in the prevention of chronic diseases including cancer, has received a great deal of attention during the past few decades. The term "Cancer" represents multiple disease states with varying biological complexities. The strongest link between vitamin D and cancer is provided by ecological and studies like observational, in preclinical models. It is apparent that vitamin D exerts diverse biological responses in a tissue specific manner. Moreover, several human factors could affect bioactivity of vitamin D. The mechanism(s) underlying vitamin D initiated anti-carcinogenic effects are diverse and includes changes at the muti-system levels. The oncogenic environment could easily corrupt the traditional role of vitamin D or could ensure resistance to vitamin D mediated responses. Several researchers have identified gaps in our knowledge pertaining to the role of vitamin D in cancer. Further areas are identified to solidify the role of vitamin D in cancer control strategies.

This paper explores news media discourse about care.data: an NHS England programme of work for amalgamating and sharing patient data from primary care for planning and research. It was scrapped in 2016 after three years of public outcry, delays and around 1.5 million opt-outs. I examine UK news media coverage of this programme through the 'fire object' metaphor, focusing upon the visions of purpose and value it inspired, the abrupt discontinuities, juxtapositions and transformations it performed, and the matters of concern that went unheeded. Findings suggest that, in care.data's pursuit of a societal consensus on NHS patient data exploitations, various visions for new and fluid data flows brought to presence narratives of transforming the NHS, saving lives, and growing the economy. Other realities and concerns that mattered for certain stakeholders, such as data ownership and commercialisation, public engagement and informed consent, commitment and leadership, operational capabilities, and NHS privatisation agendas, remained absent or unsettled. False dichotomies kept the controversy alive, sealing its fate. I conclude by arguing that such failed programmes can turn into phantom-like objects, haunting future patient data schemes of similar aspirations. The paper highlights the role news media can have in understanding such energetic public controversies.

Controversies surrounding social media platforms have provided opportunities for institutional reflexivity amongst users and regulators on how to understand and govern platforms. Amidst contestation, platform companies have continued to enact projects that draw upon existing modes of privatized governance. We investigate how social media companies have attempted to achieve closure by continuing to set the terms around platform governance. We investigate two projects implemented by Facebook (Meta)-authenticity regulation and privacy controls-in response to the Russian Interference and Cambridge Analytica controversies surrounding the 2016 U.S. Presidential Election. Drawing on Goffman's metaphor of stage management, we analyze the techniques deployed by Facebook to reinforce a division between what is visible and invisible to the user experience. These platform governance projects propose to act upon front-stage data relations: information that users can see from other users-whether that is content that users can see from "bad actors", or information that other users can see about oneself. At the same time, these projects relegate back-stage data relations-information flows between users constituted by recommendation and targeted advertising systems-to invisibility and inaction. As such, Facebook renders the user experience actionable for governance, while foreclosing governance of back-stage data relations central to the economic value of the platform. As social media companies continue to perform platform governance projects following controversies, our paper invites reflection on the politics of these projects. By destabilizing the boundaries drawn by platform companies, we open space for continuous reflexivity on how platforms should be understood and governed.

Dietetic practice aims to help people modify their diet to slow disease progression and manage disease-related complications while also meeting their nutritional and personal dietary needs. This can be challenging in people with kidney failure undergoing dialysis, particularly in our current food environment and culture. Fortunately, advancements in nutritional-behavioral science and technology are providing new avenues and resources to help meet the challenge. However, progress is slow, and much of dietetic practice in the dialysis population still relies on the interpretation, translation, and application of low-quality, indirect evidence. This Special Issue of Seminars in Dialysis provides readers with an update on and critical insights into some of the major issues and controversies impacting the field of kidney nutrition today.

This paper presents a corpus of Spanish news posts obtained from X with the annotation of controversy made via crowdsourcing. A total of 60 tweets were obtained from 8 different newspapers. For the annotation task, a survey was developed and sent to 31 different participants to answer it with the controversy level they perceived from the news post summary and headline presented on the post. The most frequent selected option was assigned as the initial controversy level of the post. The final annotation of the corpus was made via an analysis of the raw data by computing the Inter Annotator Agreement (IAA). The analysis showed that the binarization of the data was the most convenient way to annotate it. A potential use for this dataset is detailed in further sections.
RESUMO
BACKGROUND: Nursing students must graduate prepared to bravely enact the art and science of nursing in environments infiltrated with ethical challenges. Given the necessity and moral obligation of nurses to engage in discourse within nursing ethics, nursing students must be provided a moral supportive learning space for these opportunities. Situating conversations and pedagogy within a brave space may offer a framework to engage in civil discourse while fostering moral courage for learners. RESEARCH OBJECTIVE: The aim of this research is to explore the influence of a structured self-assessment tool called the ESA "Engagement Self-Assessment" on the alignment and creation of a brave space in a nursing ethics course. RESEARCH DESIGN: This study used an exploratory, cross-sectional survey design. PARTICIPANTS AND STUDY SETTING: Data from 39 undergraduate nursing students enrolled in a nursing healthcare ethics & law course using the ESA were recruited. ETHICAL CONSIDERATIONS: Participation was voluntary and informed without coercion. Written consent was obtained prior to participation. Research ethics approval was obtained by the Institutional Research Ethics Board of the recruited participants (Ethics # 2022-23-03). FINDINGS: The ESA provided structured self-reflection on the impact of shared vulnerability within a brave space. However, commitment to a brave space was not strongly influenced by the ESA, but rather by a mutual "commitment to others." CONCLUSION: A teaching tool such as an ESA can be used to facilitate instructor expectations of civil discourse and discussion of difficult topics. Rules of engagement such as those found in brave spaces can help transform fear of vulnerability into authentic growth for learners. A morally supportive learning space can support critical opportunities for ethical development. This study provides insight into how self-assessment and the use of a brave space in nursing ethics education can facilitate a morally supportive learning space.

British systematics was distinctly marked by a raft of vituperative controversies around the turn of the 1830s. After the local collapse of broad consensus in the Linnaean system by 1820, the emergence of new schemes of classification-most notably, the "quinarian" system of William Sharp Macleay-brought with it an unprecedented register of public debate among zoologists in Britain, one which a young Charles Darwin would bitterly describe to his friend John Stevens Henslow in October 1836 as possessing a "mean quarrelsome spirit," conducted in "a manner anything but like that of gentlemen." This article aims to provide a social and conceptual account of the remarkable tenor of zoological discourse in Britain in the late 1820s and early 1830s, with joint attention to the philosophical and interpersonal commitments at play. In doing so, it analyzes the three of the period's most striking public controversies, each of which counted key advocates of the quinarian system as central participants.

BACKGROUND: Practically every facet of the most common odontogenic tumor, odontoma, has been covered by an extensive volume of literature. However, uncertainty about its precise history has persisted. MATERIALS AND METHODS: The historical evolution of odontoma was traced with reference to the original illustrations that accompanied European and American reports published at the beginning of the 19th century and also at the turn of the century. RESULTS: The prevailing views regarding the first description of odontoma by Oudet of Paris in 1809 and the original designation "odontome" by Broca of Paris in 1867 are not entirely accurate. Before Broca's suggested term, "exostose dentaire" (dental exostosis) and "tumeur dentaire" (dental tumor) proposed by Oudet and Forget of Paris, respectively, were popular terms adopted in France, while in Briatin the terms "warty tooth" and "supernumerary teeth" proposed by Salter and Tomes of London, respectively, were widely coined. The original illustrations of complex odontoma were published by Wedl of Vienna in 1851, and in 1862 Tomes published the first drawing of compound odontoma denticles. Before the advent of diagnostic radiography in the early 1900s, spontaneous exposure or eruption of odontoma followed by secondary infection was very common. In 1887-1888, Bland Sutton of London criticized Broca's monumental research and formulated the first modern classification which, in essence, remains valid today. At that time, large osteomas of the maxilla were inappropriately classified as odontomas by many pathologists because of Bland Sutton's influential view. Interestingly, the first radiographic evidence of odontoma was published by the American oral surgeon Gilmer in 1899. CONCLUSION: In view of their fundamental achievements, the names of Wedl, Salter, Broca and Bland Sutton have been closely associated with the true history of odontoma.

AIMS: Since the Nobel Prize in Physiology or Medicine was awarded in 1923 to FG Banting and JJR Macleod, many voices have been raised against this decision. The bitterest protest was that of the Romanian scientist Nicolae C. Paulescu. In 2002, The Romanian Academy of Sciences, the European Association for the Study of Diabetes (EASD) and the International Diabetes Federation (IDF) planned to hold a series of academic events the following year in Paris to acknowledge Paulescu's scientific merits in the discovery of the antidiabetic hormone. However, the initiative was cancelled in August 2003, when the European Center of the Simon Wiesenthal Foundation (SWC) accused Paulescu of being antisemitic. The authors of this manuscript have decided to approach "the Paulescu case" from its double aspect, scientific and sociopolitical, to analyze the circumstances surrounding the discovery of the antidiabetic hormone, and Paulescu's alleged antisemitic past in the historical context of the Romanian nation in the interwar period. METHODS: We contacted the SWC and people related to the 2003 events in Paris. We performed a comparative review of the documents published by the Toronto group and by Paulescu and analyzed the correspondence and articles generated by international experts from the scientific community interested in the controversy. We carried out an exhaustive bibliographic search through several online catalogs (INDEXCAT, NLM Gateway, EUREKA, MEDHIST). We travelled to Bucharest, where we visited Paulescu's house-museum, interviewed a former student of the Romanian professor, and a prominent medical historian who was knowledgeable about Paulescu's scientific and political biography. Dan Angelescu, son of Dr. Constantin Angelescu (1904-1990), Paulescu's nephew and collaborator, provided us with a copy of all the available documentation from Paulescu's personal archive. It constitutes an essential source for understanding Paulescu's personal, political and academic biography. Archives consulted: RomânÇ Academy (Bucharest).

Books consulted for information on the history of Romania and antisemitism: "Nationalist ideology and antisemitism. The case of Romanian intellectuals in the 1930s", by Leon Volovici; "The mystique of ultranationalism: History of the Iron Guard, Romania, 1919-1941" by Francisco Vega; "Romania 1866-1947", by Keith Hitchins; "History of Romania. Compendium", by Ioan-Aurel Pop and Joan Bolovan; "The Holocaust in Romania. The destruction of Jews and Gypsies under the Antonescu regime, 1940-1944", by Radu Ioanid; "The Jews of East Central Europe between the World Wars", by Ezra Mendelson; "Cultural Politics in Greater Romania. Regionalism, Nation Building and Ethnic Struggle, 1918-1930", by Irina Livezeanu, and "Judeophobia. How and when it is born, where and why it survives", by Gustavo Daniel Perednik. Articles are referenced in the bibliography section at the end of the manuscript. RESULTS: A-Nicolae Paulescu developed an intense long-term research activity, which included complete pancreatectomy and preparation of a pancreatic extract (PE) containing the antidiabetic hormone he called pancreina. Parenteral administration of the PE achieved excellent results in the treatment of experimental diabetes in dogs and induction of hypoglycemia in the healthy animal. This work was initiated before 1916 and published at least eight months antedating the publication of the first article by Banting and Best (February 1922), who were acquainted with Paulescu's results, but misinterpreted them. The pancreatic extract of the two Canadian researchers, -iletin/insulin-, only achieved similar results to that of the Romanian scientist once they abandoned the use of the "degenerated pancreas" extract (ligation of the ductal system), replacing it with the pancreas of adult or fetal bovine. Pancreina and insulin were very similar. The award of the Nobel Prize in Physiology or Medicine to FG Banting and JJR Macleod in October 1923 honored the successful clinical use of insulin in patients with diabetes mellitus. Paulescu's achievements were ignored. B-Nicolae Paulescu publicly manifested his Judeophobic ideology on multiple occasions in academic and political interventions and in publications and participated with other figures from the Romanian intellectual sphere in the founding of the Uniunea NaÈional CrestinÇ (UNC, National Christian Union) in 1922 and of the Liga ApÇrÇrii NaÈional CresÈine (LANC, League for Christian National Defense) in 1923, antisemitic far-right political parties, associated with an irrational Christian orthodoxy and hatred of Jews. Paulescu played a pivotal role in the spread of antisemitism. CONCLUSIONS: A-The Romanian scientist NC Paulescu started an intense research program aimed at the isolation of the antidiabetic hormone before 1916, including an original procedure of pancreatectomy in the dog and the elaboration of a pancreatic extract that achieved excellent results in the treatment of experimental diabetes, demonstrating its beneficial effects on the metabolism of carbohydrates, proteins and fats and reducing both glycosuria and glycemia and the urinary excretion of ketone bodies of depancreatized dogs toward normality. The results of these investigations were published in 1920 and 1921, predating the first report published by FG ââBanting and CH Best in February 1922. It has been sufficiently demonstrated that Canadian researchers were aware of Paulescu's excellent results, mentioning them only in passing, albeit erroneously misrepresenting key results of the Romanian scientist's publication in the aforementioned seminal Canadian article. Expert historians and international scientists have recognized that the pancreatic extract that Paulescu called pancreina and that obtained by Banting and Best, insulin, were very similar. The October 1923 award of the Nobel Prize in Physiology or Medicine to FG Banting and JJR Macleod ignored Paulescu's scientific achievements in the treatment of experimental diabetes and rewarded the extraordinary advance of insulin treatment in human diabetes. B-At the end of August 2003, a few days before the date of the celebration at the Hôtel Dieu in Paris of the scheduled program of tribute to the scientific merits of NC Paulescu and his important contribution to the discovery of the antidiabetic hormone, convened by the Romanian Academy and the International Diabetes Federation, the Wiesenthal Foundation publicly accused the Romanian scientist of being an antisemite, an act that determined the cancellation of the announced events. The exhaustive investigation of the personal convictions and antisemitic behavior of Nicolae C. Paulescu has undoubtedly documented the Judeophobic ideology of the Romanian scientist, linked to his orthodox religious radicalism, manifested in multiple documents (mostly pamphlets) and interventions in collaboration with other relevant personalities of the Romanian intelligentsia of his time. Furthermore, Paulescu participated in the creation of political organizations of the most radical extreme right that played a fundamental role in the spread of antisemitism amongst the Romanian population and the university community.

This paper examines possible causes, consequences, and potential solutions for addressing vaccine hesitancy in the United States, focusing on the perspectives of academic scientists. By examining the experiences of scientists, who are arguably a critical community in US society, we gain deeper insights into how they understand the complexities of vaccine hesitancy and whether their insights and opinions converge with or diverge from the current literature. We present findings from a national survey of a representative sample of academic scientists from the fields of biology and public health regarding vaccine hesitancy and related topics. Empirical analysis using descriptive, bivariate, and multivariate analyses covers multiple topics, including vaccine controversy, trust in science, causes of vaccine hesitancy, preferred policy and regulatory approaches, risk perceptions, and scientists' ethics and perceived communication roles. The results highlight a diversity of opinions within the scientific community regarding how to improve science-society communication in regard to vaccines, including the need to be transparent and candid to the public about the risk of vaccines and their research.
RESUMO
In her controversial paper, Anna Smajdor proposes that brain-dead people could be used as gestation units for prospective parents unable or unwilling to undertake the act themselves-what she terms whole body gestational donation (WBGD). She explores the ethical issues of such an idea and, comparing it with traditional organ donation, asserts that such deceased surrogacy could be a way of outsourcing pregnancy's harms to a populace unable to be affected by them. She argues that if the prospect is unacceptable, this may reveal some underlying problems with traditional cadaveric organ donation. Smajdor's analysis, however, overlooks several problems arising from WBGD. This paper provides an account of those issues and argues that, in addition to WBGD being viscerally unpleasant, it is also ethically unviable. The paper starts by providing an account of WBGD before acknowledging its negative response within traditional and social media. After arguing that such cursory and gut reactions are insufficient to reject the proposal outright, this paper then provides three concerns regarding WBGD omitted by Smajdor: (i) the co-opting of life-saving organs for reproduction, (ii) the discrepancy between using cadaveric organs to save a life versus creating one, and (iii) the universalization of feminist concerns regarding reproductive body commodification. The paper concludes by tentatively agreeing with Smajdor that considering WBGD may help reveal vulnerable assumptions regarding organ donation and surrogacy, but that the significant ethical issues raised may prove insurmountable and make the intervention-thought experiment or otherwise-untenable.

It is argued that the emergence of controversial views in discussions of theoretical medicine and bioethics is best explained by the assumption of moral realism within those discursive practices. Neither of the main alternatives of realism in contemporary meta-ethics - moral expressivism and anti-realism - can account for the rise of controversies in the bioethical debate. This argument draws from the contemporary expressivist or anti-representationalist pragmatism as advanced by Richard Rorty and Huw Price, as well as the pragmatist scientific realism and fallibilism of the founder of pragmatism, Charles S. Peirce. In accordance with the fallibilist view, it is proposed that presenting controversial positions may serve epistemic purposes within bioethical debates, providing opportunities for inquiry by pointing towards problems to be solved and arguments and evidence for and against to be put forward.

What changes people's judgments on moral issues, such as the ethics of abortion or eating meat? On some views, moral judgments result from deliberation, such that reasons and reasoning should be primary drivers of moral change. On other views, moral judgments reflect intuition, with reasons offered as post-hoc rationalizations. We test predictions of these accounts by investigating whether exposure to a moral philosophy course (vs. control courses) changes moral judgments, and if so, via what mechanism(s). In line with deliberative accounts of morality, we find that exposure to moral philosophy changes moral views. In line with intuitionist accounts, we find that the mechanism of change is reduced reliance on intuition, not increased reliance on deliberation; in fact, deliberation is related to increased confidence in judgments, not change. These findings suggest a new way to reconcile deliberative and intuitionist accounts: Exposure to reasons and evidence can change moral views, but primarily by discounting intuitions.
