Practical guidelines on the prevention and management of diabetes-related foot disease (IWGDF 2023 update).

Diabetes-related foot disease results in a major global burden for patients and the healthcare system. The International Working Group on the Diabetic Foot (IWGDF) has been producing evidence-based guidelines on the prevention and management of diabetes-related foot disease since 1999. In 2023, all IWGDF Guidelines have been updated based on systematic reviews of the literature and formulation of recommendations by multidisciplinary experts from all over the world. In addition, a new guideline on acute Charcot neuro-osteoarthropathy was created. In this document, the IWGDF Practical Guidelines, we describe the basic principles of prevention, classification and management of diabetes-related foot disease based on the seven IWGDF Guidelines. We also describe the organisational levels to successfully prevent and treat diabetes-related foot disease according to these principles and provide addenda to assist with foot screening. The information in these practical guidelines is aimed at the global community of healthcare professionals who are involved in the care of persons with diabetes. Many studies around the world support our belief that implementing these prevention and management principles is associated with a decrease in the frequency of diabetes-related lower-extremity amputations. The burden of foot disease and amputations is increasing at a rapid rate, and comparatively more so in middle to lower income countries. These guidelines also assist in defining standards of prevention and care in these countries. In conclusion, we hope that these updated practical guidelines continue to serve as a reference document to aid healthcare providers in reducing the global burden of diabetes-related foot disease.

Standards for the development and methodology of the 2023 IWGDF guidelines.

AIMS: Diabetes-related foot disease is a major source of patient burden and societal costs. Investing in evidence-based international guidelines on diabetes-related foot disease is important to reduce this burden and costs, provided the guidelines are focused on outcomes important to key stakeholders and are evidence-based and properly implemented. MATERIALS AND METHODS: The International Working Group on the Diabetic Foot (IWGDF) has published and updated international guidelines since 1999. The 2023 updates were made using the Grading of Recommendations Assessment Development and Evaluation evidence-to-decision framework. This concerns formulating relevant clinical questions and important outcomes, conducting systematic reviews of the literature and meta-analyses where appropriate, completing summary of judgement tables, and writing recommendations that are specific, unambiguous and actionable, along with their transparent rationale. RESULTS: We herein describe the development of the 2023 IWGDF Guidelines on the prevention and management of diabetes-related foot disease, which consists of seven chapters, each prepared by a separate working group of international experts. These chapters provide guidelines related to diabetes-related foot disease on prevention; classification of diabetes-related foot ulcer, offloading, peripheral artery disease, infection, wound healing interventions, and active Charcot neuro-osteoarthropathy. Based on these seven guidelines, the IWGDF Editorial Board also produced a set of practical guidelines. Each guideline underwent extensive review by the members of the IWGDF Editorial Board as well as independent international experts in each field. CONCLUSIONS: We believe that the adoption and implementation of the 2023 IWGDF guidelines by healthcare providers, public health agencies, and policymakers will improve the prevention and management of diabetes-related foot disease, and subsequently reduce the worldwide patient and societal burden caused by this disease.

Radiological protection in human research ethics using a case study: toward update of the ICRP Publication 62.

The benefits of biomedical research involving humans are well recognised, along with the need for conformity to international standards of science and ethics. When human research involves radiation imaging procedures or radiotherapy, an extra level of expert review should be provided from the point of view of radiological protection. The relevant publication of the International Commission for Radiological Protection (ICRP) is now three decades old and is currently undergoing an update. This paper aims to provoke discussions on how the risks of radiation dose and the benefits of research should be assessed, using a case study of diagnostic radiology involving volunteers for whom there is no direct benefit. Further, the paper provides the current understanding of key concepts being considered for review and revision-such as the dose constraint and the novel research methods on the horizon, including radiation biology and epidemiology. The analysis revisits the perspectives described in the ICRP Publication 62, and considers the recent progress in both radiological protection ethics and medical research ethics.

Marshalling the Potential of Auger Electron Radiopharmaceutical Therapy.

Auger electron (AE) radiopharmaceutical therapy (RPT) may have the same therapeutic efficacy as α-particles for oncologic small disease, with lower risks of normal-tissue toxicity. The seeds of using AE emitters for RPT were planted several decades ago. Much knowledge has been gathered about the potency of the biologic effects caused by the intense shower of these low-energy AEs. Given their short range, AEs deposit much of their energy in the immediate vicinity of their site of decay. However, the promise of AE RPT has not yet been realized, with few agents evaluated in clinical trials and none becoming part of routine treatment so far. Instigated by the 2022 "Technical Meeting on Auger Electron Emitters for Radiopharmaceutical Developments" at the International Atomic Energy Agency, this review presents the current status of AE RPT based on the discussions by experts in the field. A scoring system was applied to illustrate hurdles in the development of AE RPT, and we present a selected list of well-studied and emerging AE-emitting radionuclides. Based on the number of AEs and other emissions, physical half-life, radionuclide production, radiochemical approaches, dosimetry, and vector availability, recommendations are put forward to enhance and impact future efforts in AE RPT research.

Development and the social sciences: international agencies in Brazilian favelas in the 1960s. / Desenvolvimento e ciências sociais: as agências internacionais nas favelas na década de 1960.

An analysis is presented of the work of three international entities in Brazilian favelas in the 1960s: Brasil-Estados Unidos Movimento, Desenvolvimento e Organização de Comunidade; Ação Comunitária do Brasil; and the United Nations. These entities conveyed the ideal of developmentalism through technical cooperation with countries deemed underdeveloped, drawing on the pure and applied social sciences through community development. Documents from the Anthony Leeds archive at Casa de Oswaldo Cruz were used to analyze these entities' actions in the favelas and their conceptions of development. Their official documents were compared, including newspapers and programs, as well as fieldnotes and letters by social scientists engaged in fieldwork in favelas in the period.

O artigo apresenta uma análise da atuação de órgãos internacionais nas favelas na década de 1960: o Brasil-Estados Unidos Movimento, Desenvolvimento e Organização de Comunidade, a Ação Comunitária do Brasil e a Organização das Nações Unidas. Tais entidades veicularam o ideal desenvolvimentista pela cooperação técnica aos países considerados subdesenvolvidos, articulando ciências sociais puras e aplicadas por meio do desenvolvimento de comunidade. Os documentos do Fundo Anthony Leeds custodiados na Casa de Oswaldo Cruz foram utilizados para analisar as ações dessas agências nas favelas e as suas concepções de desenvolvimento. Foram comparados documentos oficiais desses órgãos, como jornais e programas, com notas de campo e cartas de cientistas sociais que faziam trabalho de campo nas favelas no período.

Assessment of Occupational Carcinogenic Risk by Comparing Data from the Italian Register of Occupational Exposures to Carcinogens (SIREP) with the International Agency for Research on Cancer (IARC) Evidence.

In Italy, the National Register on Occupational Exposure to Carcinogens (SIREP) is established pursuant to article 243 of Legislative Decree 81/2008 and is aimed to collect information on the exposure of workers to carcinogens transmitted by employers. The aim of this study is to assess its level of implementation comparing prevailing carcinogens reported in SIREP with the monitoring of risks in the workplace evidenced by the International Agency for Research on Cancer (IARC). The data reported in the SIREP have been integrated with IARC and the database on carcinogenic risk in the workplace named MATline in order to build a matrix containing the carcinogens classified according to the IARC (Group 1 and 2A agents) and to a semi-quantitative indicator of risk level (High or Low) calculated upon the number of exposures reported in SIREP. The matrix contains the following data: carcinogens, economic sector (NACE Rev2 coding) and cancer sites. The comparison between SIREP and IARC evidence allowed us to highlight situations with a high risk of carcinogenicity and to address appropriate actions of prevention to contain the risks of exposure to carcinogenic substances.

Vancouver call for action to strengthen expertise in radiological protection worldwide.

Ionising radiation has been used for over a century for peaceful purposes, revolutionising health care and promoting well-being through its application in industry, science, and medicine. For almost as long, the International Commission on Radiological Protection (ICRP) has promoted understanding of health and environmental risks of ionising radiation and developed a protection system that enables the safe use of ionising radiation in justified and beneficial practices, providing protection from all sources of radiation. However, we are concerned that a shortage of investment in training, education, research, and infrastructure seen in many sectors and countries may compromise society's ability to properly manage radiation risks, leading to unjustified exposure to or unwarranted fear of radiation, impacting the physical, mental, and social well-being of our peoples. This could unduly limit the potential for research and development in new radiation technologies (healthcare, energy, and the environment) for beneficial purposes. ICRP therefore calls for action to strengthen expertise in radiological protection worldwide through: (1) National governments and funding agencies strengthening resources for radiological protection research allocated by governments and international organisations, (2) National research laboratories and other institutions launching and sustaining long-term research programmes, (3) Universities developing undergraduate and graduate university programmes and making students aware of job opportunities in radiation-related fields, (4) Using plain language when interacting with the public and decision makers about radiological protection, and (5) Fostering general awareness of proper uses of radiation and radiological protection through education and training of information multipliers. The draft call was discussed with international organisations in formal relations with ICRP in October 2022 at the European Radiation Protection Week in Estoril, Portugal, and the final call announced at the 6th International Symposium on the System of Radiological Protection of ICRP in November 2022 in Vancouver, Canada.

Showcasing the international atom: the IAEA Bulletin as a visual science diplomacy instrument, 1958-1962.

When the International Atomic Energy Agency (IAEA) began operations in 1958, one of its first routine tasks was to create and circulate a brief non-technical periodical. This article analyses the creation of the IAEA Bulletin and its circulation during its first years. It finds that diplomatic imperatives both in IAEA leadership circles and in the networks outside them shaped the form and appearance of the bulletin. In the hands of the IAEA's Division of Public Information, the bulletin became an instrument of science diplomacy, its imagery conveying the motivations for member states to strengthen ties with the IAEA, while simultaneously persuading them to accept the hierarchies and geopolitical logics implicit in those relations, as well as to endorse the central position of the IAEA as a clearing house and authority of globally circulating nuclear objects and information.
