Honores a Sir Ernest Shackleton en Sanidad Militar / Honors to Sir Ernest Shackleton in Military Health / Honras a Sir Ernest Shackleton em Saúde Militar

Ernest Shackleton ha sido en la historia, un personaje que dejó huella como ejemplo de resiliencia y liderazgo. En 1914 realizó como jefe de expedición su segundo viaje antártico, frustrado por el hundimiento de su buque insignia. La operación de rescate del grueso de la tripulación varada en el continente más meridional lo llevó a recalar en Montevideo. Desde este puerto partió el buque Instituto de Pesca N°1, con tripulación de Uruguay y Shackleton incluido, no logrando completar el salvamento. De esta acción nació el aprecio hacia la persona del explorador por parte del gobierno de la República. En su postrer travesía, ya fallecido llegó a las Islas Georgia del Sur y a su cuerpo se le realizó un proceso de conservación para ser traído a nuestro país y continuar viaje al puerto de origen en Inglaterra. Es en esa circunstancia que el gobierno del doctor Baltasar Brum solicitó a la Comisión Permanente del Parlamento, se le rindieran honores fúnebres de Ministro de Estado. El embalsamado del cuerpo fue realizado el 30 de enero de 1922, por parte de personal médico y técnico del Hospital Militar, así como los honores que le rindieron por el Servicio de Sanidad del Ejército y la Armada.

Ernest Shackleton has been in history, a character who left his mark as an example of resilience and leadership. In 1914, as expedition leader, he made his second Antarctic voyage, frustrated by the sinking of his flagship. The operation to rescue the bulk of the crew stranded on the southernmost continent led him to Montevideo. The Instituto de Pesca N°1, with Uruguayan crew and Shackleton included, departed from this port, but was unable to complete the rescue. From this action was born the appreciation of the explorer by the government of the Republic. In his last voyage, when he died, he reached the South Georgia Islands and his body underwent a preservation process to be brought to our country and continue his voyage to the port of origin in England. It is in this circumstance that the government of Dr. Baltasar Brum requested the Permanent Commission of the Parliament to pay him the funeral honors of a Minister of State. The embalming of the body was carried out on January 30, 1922, by medical and technical personnel of the Military Hospital, as well as the honors rendered by the Army and Navy Health Service.

Ernest Shackleton deixou sua marca na história como um exemplo de resiliência e liderança. Em 1914, ele fez sua segunda viagem à Antártica como líder da expedição, frustrado pelo naufrágio de seu navio principal. A operação para resgatar a maior parte da tripulação encalhada no continente mais ao sul o levou a Montevidéu. O Instituto de Pesca N°1, com tripulação do Uruguai e Shackleton incluído, partiu desse porto, mas não conseguiu concluir o resgate. Essa ação deu origem ao reconhecimento do explorador pelo governo da República. Em sua última viagem, quando morreu, chegou às Ilhas Geórgia do Sul e seu corpo foi preservado para que pudesse ser trazido ao nosso país e continuar sua viagem até o porto de origem na Inglaterra. Foi nessa circunstância que o governo do Dr. Baltasar Brum solicitou ao Comitê Permanente do Parlamento que lhe prestasse as honras fúnebres de um Ministro de Estado. O embalsamamento do corpo foi realizado em 30 de janeiro de 1922, pela equipe médica e técnica do Hospital Militar, bem como as honras prestadas a ele pelo Serviço de Saúde do Exército e da Marinha.

Medium-term mortality after hip fractures and COVID-19: A prospective multi-centre UK study / 中华创伤杂志(英文版)

PURPOSE@#The COVID-19 pandemic has caused 1.4 million deaths globally and is associated with a 3-4 times increase in 30-day mortality after a fragility hip fracture with concurrent COVID-19 infection. Typically, death from COVID-19 infection occurs between 15 and 22 days after the onset of symptoms, but this period can extend up to 8 weeks. This study aimed to assess the impact of concurrent COVID-19 infection on 120-day mortality after a fragility hip fracture.@*METHODS@#A multi-centre prospective study across 10 hospitals treating 8% of the annual burden of hip fractures in England between 1st March and 30th April, 2020 was performed. Patients whose surgical treatment was payable through the National Health Service Best Practice Tariff mechanism for "fragility hip fractures" were included in the study. Patients' 120-day mortality was assessed relative to their peri-operative COVID-19 status. Statistical analysis was performed using SPSS version 27.@*RESULTS@#A total of 746 patients were included in this study, of which 87 (11.7%) were COVID-19 positive. Mortality rates at 30- and 120-day were significantly higher for COVID-19 positive patients relative to COVID-19 negative patients (p < 0.001). However, mortality rates between 31 and 120-day were not significantly different (p = 0.107), 16.1% and 9.4% respectively for COVID-19 positive and negative patients, odds ratio 1.855 (95% CI 0.865-3.978).@*CONCLUSION@#Hip fracture patients with concurrent COVID-19 infection, provided that they are alive at day-31 after injury, have no significant difference in 120-day mortality. Despite the growing awareness and concern of "long-COVID" and its widespread prevalence, this does not appear to increase medium-term mortality rates after a hip fracture.

Analysis of the factors contributing to endometriosis in China and UK / 南方医科大学学报

OBJECTIVE@#To explore the differences in the factors associated with endometriosis between Chinese and British patients.@*METHODS@#This case-control study was conducted in 387 patients with endometriosis and 199 non-endometriosis patients admitted to John Radcliffe Hospital (Oxford, UK) and in 101 patients with endometriosis and 50 non-endometriosis patients admitted in the First Affiliated Hospital of Guangzhou University of Chinese Medicine. The clinical data including height, weight, body mass index, marital status, employment, menstruation, fertility, and operation reasons were collected via a standardized WERF EPHect questionnaire.@*RESULTS@#Multivariate logistic regression analysis indicated that body mass index, surgery for dysmenorrhea, history of pregnancy, counts of previous surgeries for endometriosis and status of employment were all significantly associated with endometriosis in the UK (P < 0.05), while a history of dysmenorrhea was significantly correlated with endometriosis in Chinese patients (P < 0.05).@*CONCLUSION@#Dysmenorrhea may be the most important common factor associated with endometriosis in China and the UK, but the other factors contributing to endometriosis may differ between these two countries.

COVID-19 meta-analyses: a scoping review and quality assessment / Metanálises sobre COVID-19: revisão de escopo e análise de qualidade

ABSTRACT Objective: To carry out a scoping review of the meta-analyses published regarding about coronavirus disease 2019 (COVID-19), evaluating their main characteristics, publication trends and methodological quality. Methods: A bibliometric search was performed in PubMed®, Scopus and Web of Science, focusing on meta-analyses about COVID-2019 disease. Bibliometric and descriptive data for the included articles were extracted and the methodological quality of the included meta-analyses was evaluated using A Measurement Tool to Assess Systematic Reviews. Results: A total of 348 meta-analyses were considered eligible. The first meta-analysis about COVID-19 disease was published on February 26, 2020, and the number of meta-analyses has grown rapidly since then. Most of them were published in infectious disease and virology journals. The greatest number come from China, followed by the United States, Italy and the United Kingdom. On average, these meta-analyses included 23 studies and 15,200 participants. Overall quality was remarkably low, and only 8.9% of them could be considered as of high confidence level. Conclusion: Although well-designed meta-analyses about COVID-19 disease have already been published, the majority are of low quality. Thus, all stakeholders playing a role in COVID-19 deseases, including policy makers, researchers, publishers and journals, should prioritize well-designed meta-analyses, performed only when the background information seem suitable, and discouraging those of low quality or that use suboptimal methods.

RESUMO Objetivo: Realizar uma revisão de escopo das metanálises publicadas sobre a doença pelo coronavírus 2019 (COVID-19), avaliando suas principais características, tendências de publicação e qualidade metodológica. Métodos: Uma busca bibliométrica foi realizada em PubMed®, Scopus e Web of Science, com foco em metanálises sobre a doença pelo COVID-19. Foram extraídos dados bibliométricos e descritivos dos artigos incluídos, e a qualidade metodológica foi avaliada usando a ferramenta A Measurement Tool to Assess Systematic Reviews. Resultados: Um total de 348 metanálises foram consideradas elegíveis. A primeira delas foi publicada em 26 de fevereiro de 2020, e, desde então, o número dessas publicações cresceu rapidamente. A maioria foi publicada em periódicos de infectologia e virologia. Grande parte é proveniente da China, seguida dos Estados Unidos, da Itália e do Reino Unido. Em média, as metanálises incluíram 23 estudos e 15.200 participantes. Em geral, a qualidade metodológica foi baixa, e apenas 8,9% delas podem ser consideradas de algum grau de confiabilidade Conclusão: Embora algumas metanálises bem conduzidas sobre a doença pelo COVID-19 tenham sido publicadas, a maioria apresenta baixa qualidade. Todos os envolvidos na abordagem da doença pelo COVID-19, incluindo formuladores de políticas, pesquisadores, editoras e periódicos, devem dar prioridade a metanálises de alta qualidade, realizadas apenas quando os dados são viáveis, e desencorajar as de baixa qualidade ou conduzidas com métodos subótimos.

The impact of the COVID-19 pandemic on the mental health of young people: A comparison between China and the United Kingdom / 中华创伤杂志(英文版)

PURPOSE@#As COVID-19 spreads globally and affects people's health, there are concerns that the pandemic and control policies may have psychological effects on young people (age from 17 to 35 years). This psychological impact might vary in different countries, and thus we compared the prevalence of self-reported psychological distress, loneliness and posttraumatic stress symptoms (PTSS) among young people in the United Kingdom (UK) and China at the beginning of the COVID-19 pandemic.@*METHODS@#Data of this study came from two sources. One source was the first wave of COVID-19 study in Understanding Society, a special wave of the UK household longitudinal study, which provided the high-quality, national-wide representative panel data. The sample comprised 1054 young people. The other source was an online survey on the mental health of 1003 young people from Shanghai, a highly developed area in China. The questionnaire included questions on the prevalence of common mental disorders (cut-off score ≥ 4), loneliness and potential PTSS (cut-off ≥ 33). Univariable analyses were conducted to test the differences in the self-reported prevalence of psychological distress and loneliness between the two groups. Multivariable logistic regression analyses were run to explore the predictors of psychological distress and loneliness among all the young people from England and Shanghai.@*RESULTS@#Among the samples with self-reported psychological distress, the UK sample accounted for 34.4% (n=1054) and the Chinese sample accounted for 14.1% (n=1003). The difference between the two groups was statistically significant (p < 0.001). Additionally, 57.1% of people in the UK and 46.7% in China reported that they sometimes or often felt lonely, of which the difference is statistically significant (p < 0.001). Regression analysis of the entire samples showed that nationality, gender, psychotherapy and loneliness were significant predictors of 12-item General Health Questionnaire scores, while the variables of age and living alone were not. Significant predictors of self-reported loneliness were the nationality, gender, age, living alone and psychotherapy. In China, 123 (12.3%) young people, 49 men (11.3%) and 74 women (13.0%), met the criteria of PTSS symptoms (cut-off scores ≥ 33). These scores were only collected in China.@*CONCLUSION@#This evidence suggests that mental health and loneliness reported by young people were lower in China than that in the UK during the studied period. More research is needed to understand these differences. If the differential negative psychological impacts are confirmed, country-specific measures of prevention and intervention should be adopted to improve the mental health of young people under the ongoing impact of the pandemic.

A review on the application of UK Biobank in neuroimaging / 生物医学工程学杂志

UK Biobank (UKB) is a forward-looking epidemiological project with over 500, 000 people aged 40 to 69, whose image extension project plans to re-invite 100, 000 participants from UKB to perform multimodal brain magnetic resonance imaging. Large-scale multimodal neuroimaging combined with large amounts of phenotypic and genetic data provides great resources to conduct brain health-related research. This article provides an in-depth overview of UKB in the field of neuroimaging. Firstly, neuroimage collection and imaging-derived phenotypes are summarized. Secondly, typical studies of UKB in neuroimaging areas are introduced, which include cardiovascular risk factors, regulatory factors, brain age prediction, normality, successful and morbid brain aging, environmental and genetic factors, cognitive ability and gender. Lastly, the open challenges and future directions of UKB are discussed. This article has the potential to open up a new research field for the prevention and treatment of neurological diseases.

Analysis of the development trend and severity of the COVID-19 panidemic in the global world / 北京大学学报(医学版)

OBJECTIVE@#To analyze the recent severity of COVID-19 in various countries.@*METHODS@#Data were ollected on the epidemic situation of COVID-19 in various countries as of January 16, 2021, and the scale and overall trend of the epidemic were retrospectively described; combined with the recent trend of newly confirmed cases, from January 10 to 16 (the 54th week) and the newly confirmed cases indexes, such as the number and incidence density the severity of the epidemic was classified. Feasible suggestions were put forward based on the variation of the virus, actual data of vaccine research and development and possible existence in many countries.@*RESULTS@#Up to January 16, 2021, there were 92 510 419 confirmed cases worldwide; 4 849 301 new confirmed cases were confirmed in the 54th week, and they were still growing. Among all the continents, the cumulative number of confirmed cases in Europe, North America, and Asia has exceeded 21 million, and the number of new confirmed cases in a single week in North America, South America and Asia were all increasing. Among the countries, the cumulative number of confirmed cases in 18 countries including the United States, India, and Brazil was more than 1 million, accounting for 77.04% of the total number of cumulative confirmed cases in the world. Eleven countries including the United States, Brazil, France, Spain, Colombia, The United Kingdom, Russia, Germany, South Africa, Italy, and India are at higher risk of the epidemic; The United States, Brazil, France, Spain, and Colombia were still experiencing new confirmed cases and increasing status, the risk of the epidemic was greater. Novel coronavirus mutates frequently, up to February 2021, there had been 3 931 mutant genotypes in the world. At the same time, a total of 11 vaccines were successfully launched, however we were still facing some troubles, such as the global shortage of vaccines, the public's willingness to vaccinate needed to be improved, and equity in the distribution of vaccines.@*CONCLUSION@#The global epidemic situation is still getting worse, with repeated epidemics in all the continents and countries, and has not been fundamentally controlled. At the continent level, North America, South America, and Europe have the most severe epidemics; at the national level, The United States, Brazil, France, Spain, Colombia and other countries have higher epidemic risks. Focusing on the severely affected countries will help bring the global epidemic under control as soon as possible. Under the premise of ensuring the safety and effectiveness of the vaccines, it is a key and feasible direction to improve the yield and vaccination rate of the vaccines, shorten the onset time of the vaccines and prolong the immune persistence.

Medidas de enfrentamento dos efeitos econômicos da Pandemia Covid-19: panorama internacional e análise dos casos dos Estados Unidos, do Reino Unido e da Espanha / Texto para Discussão (TD) 2559: Medidas de enfrentamento dos efeitos econômicos da Pandemia Covid-19: panorama internacional e análise dos casos dos Estados Unidos, do Reino Unido e da Espanha / Português

Este texto apresenta um panorama internacional das medidas econômicas adotadas para reduzir os graves efeitos econômicos da pandemia de Sars-COV-2 em três países: Estados Unidos, Reino Unido e Espanha. A análise toma como base primordialmente documentos governamentais que normatizaram as medidas de política econômica. São analisados os diversos canais por meio dos quais a crise sanitária afeta a economia. Por um lado, estão os fatores de oferta: oferta de trabalho, produtividade do trabalho e funcionamento das cadeias produtivas. Por outro lado, encontram-se os fatores de demanda: consumo das famílias, investimento privado e comércio exterior. O terceiro canal diz respeito aos fatores financeiros que incidem sobre as variáveis de demanda e, principalmente, sobre o grau de liquidez das empresas financeiras e não financeiras. As medidas adotadas nos três países apresentam como características comuns a mobilização de grande volume de recursos fiscais e financeiros, a adoção de uma grande diversidade de instrumentos de política econômica e o uso de arranjos institucionais sofisticados em termos de regras de focalização e de mecanismos de operacionalização das medidas adotadas.

This text presents an international overview of the economic measures adopted to reduce the serious economic effects of the Sars-COV-2 pandemic in three countries: the USA, the United Kingdom and Spain. The analysis is based primarily on government documents that regulated economic policy measures. The various channels through which the health crisis affects the economy are analyzed. On one hand, there are the supply factors: labor supply, labor productivity and the functioning of production chains. On the other hand, there are demand factors: household consumption, private investment and foreign trade. The third channel concerns the financial factors on demand variables and, mainly, on the degree of liquidity of financial and non-financial companies. The measures adopted in the three countries have as common characteristics the mobilization of large volumes of fiscal and financial resources, the adoption of a wide range of economic policy instruments and the use of sophisticated institutional arrangements in terms of targeting rules and mechanisms for operationalizing the measures adopted.

O espírito de um sobrevivente / The survivor's spirit / El espíritu de un sobreviviente

Em 2018, o Sistema Único de Saúde (SUS) completou 30 anos de sua criação no Brasil. Embora reúna muitas conquistas nessas três décadas, o SUS hoje enfrenta novos desafios, impostos pela agenda liberal e conservadora em curso no país. Nesse contexto, o documentário O Espírito de 45 (2013), dirigido por Ken Loach, que destaca a criação do Serviço Nacional de Saúde (National Health Service - NHS), no Reino Unido, é um filme salutar. Tendo a cidadania e o bem comum como grandes temas, a obra mostra como é possível, revisitando o passado, despertar o espírito combativo em defesa de uma sociedade mais justa e solidária, que privilegie o bem-estar da população em lugar do lucro e que aponte caminhos para a defesa do SUS, enquanto uma conquista do povo brasileiro.

In 2018, the SUS ­ Sistema Unificado de Saúde (Unified Health System) celebrated the 30th anniversary of its setting up in Brazil. Despite its many achievements in these three decades, nowadays SUS faces new challenges which were imposed by a liberal and conservative agenda ongoing in the country. In this context, the documentary The Spirit of '45 (2013), directed by Ken Loach, which highlights the creation of the National Health Service (NHS) in the United Kingdom, is a very important film. Addressing citizenship and the common good as major themes, the movie shows how it is possible by revisiting the past to awaken the combative spirit in favour of a fairer and more solidary society, in order to prioritize the population's wellbeing instead of the profit and to point out ways to defend SUS as an achievement of the Brazilian people.

William Shakespeare y la medicina / William Shakespeare and medicine

Si repensamos a escritores que se ocuparon de la medicina, el presente trabajo pretende destacar a William Shakespeare, como un escritor que prácticamente en toda su obra describe en sus personajes problemas de salud de todo tipo. Se harán ciertas referencias de los aspectos médicos desarrollados en la obra del escritor, advirtiendo que son sólo una parte de su extensa producción. (AU)

If we rethink writers who dealt with medicine, this paper intends to highlight William Shakespeare, as a writer who practically describes all kinds of health problems in his characters. Certain references will be made of the medical aspects developed in the writer's work, warning that they are only part of his extensive production. (AU)

Thoracic aortic aneurysm surgery in marfan patients: a perspective from the uk

Abstract Objective: Cardiovascular complications in Marfan patients include progressive aortic root dilation which can precipitate acute aortic dissection, ruptured aorta, severe aortic regurgitation, or all the aforementioned. Such complications can be fatal and the cause of death prior to any surgical intervention. We set out to identify the Marfan population in England and Wales and present their surgical outcomes. Methods: A total of 306 patients with Marfan syndrome who underwent aortic root surgery were identified between April 2007 and March 2013 from NICOR database. We examined the perioperative characteristics of such cohort along with in-hospital outcomes and survival. Results: Root and ascending segment procedures on Marfan patients performed in 3.3% of the total cohort by NICOR root surgery patients. The median reported age was 40 years (IQR = 29-49 years) and 100 (32.7%) were female. Of the patients analysed, 17.3% were treated non-electively and 68.6% of them received concomitant valve procedure. The in-hospital mortality was 2.0%. Reoperation for bleeding was required in 8.2% of patients and 1.3% of them suffered a cerebrovascular accident (CVA). Mortality at 1 year was reported as 5.5%. Conclusion: The outcomes of surgery on the root and ascending aorta in Marfan patients in the United Kingdom are satisfactory; however, the overall complexities of this patient population are not well understood and would benefit from further investigations.

Governança global, regulamentação flexível e os ensaios clínicos na medicina regenerativa no Reino Unido e na União Europeia / Global Governance, Flexible Regulation and Clinical Trials in Regenerative Medicine in the United Kingdom and the European Union

Resumo A medicina regenerativa encontra-se em fase de desenvolvimento dos ensaios clínicos em terapias celulares (TC), na sua manufatura e na sua adoção gradual dentro dos sistemas de saúde. Entretanto, há uma série de lacunas e contradições na governança e regulamentação na área e o objetivo principal deste artigo é sua discussão dentro das tendências globais, já que esses processos afetam de modo substantivo a saúde coletiva global e encontram-se ainda escassamente resolvidos. O texto foca nos processos prevalentes nos ensaios clínicos com TC em duas lideranças internacionais, o Reino Unido e a União Europeia, utilizando a análise bibliográfica e de conteúdo. O texto conclui com uma discussão das principais vantagens e desvantagens para a saúde coletiva global da transição de um modelo científico de comprovação das novas terapias celulares para, eventualmente, outro baseado na inovação médica ou clínica. O último procede desde a fase pré-clínica com animais à aplicação das novas terapias a grupos pequenos de pacientes e, logo a seguir, a sua inserção no mercado. Muitas vezes, esse modelo se associa a flexibilidades regulatórias, a serem ilustradas no artigo, e especialmente desenhadas para aumentar a rapidez no desenvolvimento e aplicação das terapias.

Abstract Regenerative medicine is at present in a stage of development of clinical trials in cell therapies (CT), their manufacture and gradual adoption by health systems. However, there are several gaps and contradictions in governance and regulation in the area and the main aim of this article is their discussion within global trends, as these processes remain still ill- resolved while substantively affecting collective global health. The text focuses on an analysis of prevailing processes in clinical trials with CT by two leading actors, the United Kingdom, and the European Union, and is based upon bibliographical and content analyses. The article concludes with a discussion of the main advantages and disadvantages for collective global health of the transition from a conventional scientific model to test the new therapies to, eventually, one based on medical or clinical innovation. The latter proceeds from the pre-clinical research phase with animals to clinical trials with small groups of patients and subsequently, to the entrance of cell therapies into the market. Often this model is associated to flexible regulations, to be illustrated in the article, which are specifically designed to diminish time-lags between therapy development and its full application.
