RESUMEN

INTRODUCTION: Reviewing and updating research priorities is essential to assess progress and to ensure optimal allocation of financial and human resources in research. In 2001, WHO held a research priority setting workshop for herpes simplex virus type 2 (HSV-2) research in low-income and middle-income countries (LMICs). This study aimed to describe progress between 2000 and 2020 in three of the five key research priority areas outlined in the workshop: HSV-2/HIV interactions, HSV-2 control measures and HSV-2 mathematical modelling. The remaining priorities are addressed in a companion paper. METHOD: A systematic literature search of MEDLINE, CINAHL, Global Health and Cochrane databases was carried out. Relevant primary research studies based in LMICs, written in English and published on 2000-2020 were included. Papers were screened by two independent reviewers, and suitable variables were selected for manual extraction from study texts. Data were organised into an Excel spreadsheet and analysed using IBM SPSS. RESULTS: In total, 3214 discrete papers were identified, of which 180 were eligible for inclusion (HSV-2/HIV interactions, 98; control measures, 58; mathematical modelling, 24). Most studies were conducted in East Africa. The majority of the 2001 WHO HSV-2 research priorities were addressed at least in part. Overall, despite several studies describing a strong relationship between HSV-2 and the acquisition and transmission of HIV, HSV-2 control repeatedly demonstrated little effect on HIV shedding or transmission. Further, although mathematical modelling predicted that vaccines could significantly impact HSV-2 indicators, HSV-2 vaccine studies were few. Studies of antiviral resistance were also few. CONCLUSION: Since 2000, LMIC HSV-2 research addressing its control, HIV interactions and mathematical modelling has largely addressed the priorities set in the 2001 WHO HSV-2 workshop. However, key knowledge gaps remain in vaccine research, antiviral cost-effectiveness, antiviral resistance and specific geographical areas.

RESUMEN

Whereas medical practice stems from Hippocrates, cardiovascular science originates with Aristotle. The Hippocratic philosophy was championed by Galen (129-216 CE), whose advocacy of a tripartite soul found favor in the early Christian Church. In contrast, Aristotle's works were banned as heresy by ecclesiastical authority, only to survive and prosper in the Islamic Golden Age (775-1258 CE). Galen theorized that the circulation consisted of separate venous and arterial systems. Blood was produced in the liver and traveled centrifugally through veins. When arriving in the right ventricle, venous blood passed through tiny pores in the ventricular septum into the left ventricle, where it became aerated by air passing from the lungs through the pulmonary veins to the left side of the heart. Following arrival at distal sites, arterial blood disappeared, being consumed by the tissues, requiring that the liver needed to continually synthesize new blood. The heart was viewed as a sucking organ, and the peripheral pulse was deemed to result from changes in arterial tone, rather than cardiac systole. Galen's framework remained undisputed and dominated medical thought for 1,300 years, but the reintroduction of Aristotelian principles from the Islamic world into Europe (through the efforts of the Toledo School of Translators) were nurtured by the academic freedom and iconoclastic environment uniquely cultivated at the University of Padua, made possible by Venetian rebellion against papal authority. At Padua, the work of Andreas Vesalius, Realdo Colombo, Hieronymus Fabricius ab Acquapendente, and William Harvey (1543-1628) methodically destroyed Galen's model, leading to the modern concept of a closed-ended circulation. Yet, due to political forces, Harvey was ridiculed, as was James Lind, who performed the first prospective controlled trial, involving citrus fruits for scurvy (1747); it took nearly 50 years for his work to be accepted. Even the work of William Withering (1785), the father of cardiovascular pharmacology, was tarnished by professional jealously and the marketing campaign of a pharmaceutical company. Today's cardiovascular investigators should understand that major advances are routinely derided by the medical establishment for political or personal reasons; and it may take decades or centuries for important work to be accepted.

RESUMEN

Philanthropic foundations played a crucial role in rationalizating and organizing American society in the late 19th and early 20th centuries. The promotion of science was applied to medical reform, leading to the advent of genuine medical research within the framework of brand-new university hospital faculties. With the two world wars, the state became heavily involved in the field of healthcare. After 1945, it became the main source of funding for biomedical research. Philanthropy did not disappear from the institutional landscape; it continued to work in tandem with public authorities. Its role in medical research is now minor in terms of funding volume, but a strategic one in the development of projects aimed at advancing basic science and knowledge of various diseases.


Title: La philanthropie médicale aux États-Unis. Abstract: Les fondations philanthropiques ont pris une part décisive dans la rationalisation et l'organisation de la médecine dans la société américaine des débuts du xxe siècle, période pendant laquelle la promotion de la science a donné lieu à l'avènement d'une véritable recherche médicale spécialisée dans le cadre des nouvelles facultés hospitalo-universitaires. Avec les deux guerres mondiales, l'État fédéral s'est fortement engagé dans le champ de la santé. Au point qu'après 1945, il est devenu la principale source de financement de l'innovation biomédicale. La philanthropie ne disparaît pas pour autant du paysage institutionnel. Elle continue de fonctionner en tandem avec les pouvoirs publics. Son rôle est aujourd'hui minoritaire en termes de volume de financement, mais stratégique dans l'avènement de projets visant à faire avancer les connaissances sur des processus fondamentaux ainsi que sur de nombreuses maladies.

RESUMEN

The concept of the Land of Not-Unhappiness refers to the potential achievement of eliminating the pathologies of the aging process. To inform of how close we are to settling in the land, we summarize and review the achievements of research on anti-aging interventions over the last hundred years with a specific focus on strategies that slow down metabolism, compensate for aging-related losses, and target a broad range of age-related diseases. We critically evaluate the existing interventions labeled as "anti-aging," such as calorie restriction, exercise, stem cell administration, and senolytics, to provide a down-to-earth evaluation of their current applicability in counteracting aging. Throughout the text, we have maintained a light tone to make it accessible to non-experts in biogerontology, and provide a broad overview for those considering conducting studies, research, or seeking to understand the scientific basis of anti-aging medicine.

RESUMEN

The history of sex research demonstrates an ongoing coexistence of multiple, conflicting meanings of sex. This history raises questions for scientists about the deployment of a research variable that lacks precision. Cross-disciplinary collaboration between scientists and science and technology studies (STS) scholars offers a way to find solutions to this problem.

RESUMEN

Torben Fog was committed to multiple sclerosis (MS) research for more than four decades, starting before the defence of his thesis in 1948 and lasting until his death in 1987. His research was multi-facetted, making him one of the great pioneers in the study of essential parts of the pathology, immunology and treatment of MS. He has contributed with meticulous studies of the MS plaques, documenting the perivenous distribution of plaques in the spinal cord. He constructed a scoring system for the disability in MS and used a computer programme to calculate a total neurological deficit. Together with his co-workers, Fog in 1972 was the first to report the association between MS and the human leukocyte antigen system. Fog can be considered as the father of immunomodulatory therapy in MS, treating MS patients with the first transfer factor, and as early as 1980, he was the first to treat MS with intramuscular natural interferon.

RESUMEN

OBJECTIVE: This study aimed to analyse existing research on systemic sclerosis (SSc) conducted over the past 73 years to develop an essential reference for a comprehensive and objective understanding of this field of inquiry. METHODS: Using the Web of Science Core Collection, PubMed, and Scopus databases as data sources for the bibliometric analysis, we searched for published literature related to SSc over the past 73 years. The Bibliometrix package was used to analyse key bibliometric indicators, such as annual publication volume, countries, journals, author contributions, and research hotspots. RESULTS: From 1970 to 2022, the number of SSc articles steadily increased, reaching its peak in 2020-2022, with approximately 1200 papers published in each of these three years. Matucci-Cerinic et al.'s team published the most articles (425). The United States (11,282), Italy (7027), and France (5226) were the most predominant contexts. The most influential scholars in the field were Denton, Leroy, Steen, and Khanna, with H-indices of 86, 84, and 83, respectively. Arthritis and Rheumatism was the most influential journal in this field (H-index 142). High-frequency keywords in the SSc field included fibrosis (738), inflammation (242), vasculopathy (145), fibroblasts (120), and autoantibodies (118) with respect to pathogenesis, and interstitial lung disease (ILD, 708), pulmonary arterial hypertension (PAH, 696), and Raynaud's phenomenon (326) with regards to clinical manifestations. CONCLUSION: In the past three years, SSc research has entered a period of rapid development, mainly driven by research institutions in Europe and the United States. The most influential journal has been Arthritis and Rheumatism, and autoimmune aspects, vasculopathy, fibrogenesis, PAH, and ILD remain the focus of current research and indicate trends in future research.

RESUMEN

The National Institute on Aging (NIA), part of the National Institutes of Health (NIH), was founded in 1974 to support and conduct research on aging and the health and well-being of older adults. Fifty years ago, the concept of studying aging generated much skepticism. Early NIA-funded research findings helped establish the great value of aging research and provided the foundation for significant science advances that have improved our understanding of the aging process, diseases and conditions associated with aging, and the effects of health inequities, as well as the need to promote healthy aging lifestyles. Today, we celebrate the many important contributions to aging research made possible by NIA, as well as opportunities to continue to make meaningful progress. NIA emphasizes that the broad aging research community must continue to increase and expand our collective efforts to recruit and train a diverse next generation of aging researchers.
