    Systemic lupus erythematosus (SLE), a complex and heterogeneous autoimmune disease, represents a significant challenge for both diagnosis and treatment. Patients with SLE in Latin America face special problems that should be considered when therapeutic guidelines are developed. The objective of the study is to develop clinical practice guidelines for Latin American patients with lupus. Two independent teams (rheumatologists with experience in lupus management and methodologists) had an initial meeting in Panama City, Panama, in April 2016. They selected a list of questions for the clinical problems most commonly seen in Latin American patients with SLE. These were addressed with the best available evidence and summarised in a standardised format following the Grading of Recommendations Assessment, Development and Evaluation approach. All preliminary findings were discussed in a second face-to-face meeting in Washington, DC, in November 2016. As a result, nine organ/system sections are presented with the main findings; an 'overarching' treatment approach was added. Special emphasis was made on regional implementation issues. Best pharmacologic options were examined for musculoskeletal, mucocutaneous, kidney, cardiac, pulmonary, neuropsychiatric, haematological manifestations and the antiphospholipid syndrome. The roles of main therapeutic options (ie, glucocorticoids, antimalarials, immunosuppressant agents, therapeutic plasma exchange, belimumab, rituximab, abatacept, low-dose aspirin and anticoagulants) were summarised in each section. In all cases, benefits and harms, certainty of the evidence, values and preferences, feasibility, acceptability and equity issues were considered to produce a recommendation with special focus on ethnic and socioeconomic aspects. Guidelines for Latin American patients with lupus have been developed and could be used in similar settings.Fil: Pons Estel, Bernardo A..

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

    Signaling value through gender diversity : evidence from initial coin offerings

    Get PDF
    We analyze women’s participation and the effects of team gender diversity on initial coin offering (ICO) success measured by the total funding amount raised in the actual ICO and the project’s long-term survival. Using a database featuring 875 initial coin offerings between 2017 and 2019, we find that women are significantly under-represented in ICO projects (on average, only 13% of team members are women). However, for projects that do have participation of women, we find that team gender diversity increases the total funding raised in the ICO. Moreover, when we separate team members into areas of expertise or roles in the project, we find that the presence of women in critical positions, such as being a founder or having financial or legal responsibilities, significantly reduces the likelihood of long-term coin failure. Our results are consistent with the notion that investors perceive women’s participation in leadership positions as a positive signal of desirable organizational practices that will translate into better performance. Our results are also consistent with the idea that having women, who abide by ethical values and are less prone to fraud, reduces the likelihood that informationally opaque ICOs turn out to be scams.https://orcid.org/0000-0001-7675-048Xhttps://orcid.org/0000-0002-7981-4968https://orcid.org/0000-0002-9592-7890https://www.scopus.com/authid/detail.uri?authorId=55207224400https://www.scopus.com/authid/detail.uri?authorId=57191261953https://www.scopus.com/authid/detail.uri?authorId=5520641670

    Attention to global warming and the success of environmental initial coin offerings : empirical evidence

    Get PDF
    We analyze the effects of attention to global warming on the success of environmental initial coin offerings (ICOs) measured by the total funding amount raised in the actual ICOs and the long-term survival of the projects. Using a database featuring 324 environmental initial coin offerings between 2017 and 2019, we find that attention to global warming increases the total funding raised in an environmental ICO. Moreover, we find that environmental offerings that occur during periods of greater attention to global warming are significantly less likely to fail in the long term. Our results are consistent with the idea that investor attention as a market-discipline mechanism increases the likelihood of survival for environmental ICOs.https://orcid.org/0000-0001-7675-048Xhttps://orcid.org/0000-0002-7981-4968https://orcid.org/0000-0002-9592-7890https://www.scopus.com/authid/detail.uri?authorId=55207224400https://www.scopus.com/authid/detail.uri?authorId=57191261953https://www.scopus.com/authid/detail.uri?authorId=5520641670

    Titulo en ingles: Identification of Leishmania (Viannia) guyanensis in dogs in rural area municipality of Villavicencio, Meta, Colombia.RESUMEN:  La leishmaniasis cutánea canina es una enfermedad emergente en Colombia. Aunque ha sido posible establecer que el canino pueden ser parasitado por especies de Leishmania (Viannia) de alta importancia epidemiológica como L. panamensis y L. braziliensis., aún no se ha determinado su papel en la transmisión de la Leishma- niasis cutánea americana (LCA). Se tomaron muestras para estudios moleculares en la vereda La Reforma del Municipio de Villavicencio, en donde se habían encontrado 6 caninos y un humano con lesiones compatibles con Leishmaniasis cutánea. Las muestras de tejido fueron recolectadas y procesadas para la identificación del parásito a través de la técnica de Reacción en Cadena de la Polimerasa (PCR). Se utilizaron los iniciadores OL1 y OL2 para la identificación del parásito, los iniciadores B1 y B2 para determinar el Sub-género y los iniciadores especie-específicos b1-b2, g1-g2, y p1-p2 para la especie. Se encontró en el humano y un canino un patrón de amplificación de ADN compatible con el reportado para Leishmania (Viannia) guyanensis. En conclusión, la identificación de esta especie de Leishmania fue posible mediante PCR, lo cual valida su uso en estudios futuros y además sugiere la existencia de un nuevo nicho ecológico para el parasito lo que representa un importante factor de riesgo para la presentación de un brote epidémico en la población.Palabras clave: Leishmaniasis cutánea, caninos, VillavicencioSUMMARY:  The canine cutaneous leishmaniasis is an emerging disease in our country.Although it has been possible to establish that the canines can be parasitized by species of Leishmania (Viannia) high epidemiological importance such as the L. panamensis and L. braziliensis. not yet determined its role in the transmission of American cutaneous leishmaniasis (ACL).

    1324 prison suicides in 10 countries in South America: incidence, relative risks, and ecological factors

    No full text
    Purpose:&nbsp;Although suicide rates of prison populations and incidence factors have been reported for high-income countries, data from low- and middle-income regions are lacking. The purpose of the study was to estimate suicide rates among prison populations in South America, to examine prison-related factors, and to compare suicide rates between prison and general populations. Methods:&nbsp;In this observational study, we collected the numbers of suicides in prison, rates of prison occupancy, and incarceration rates from primary sources in South America between 2000 and 2017. We compared suicide rates among prisoners with incidence rates in the general populations by calculating incidence rate ratios. We assessed the effect of gender, year, incarceration rates and occupancy on suicide rates in the prison populations using regression analyses. Results:&nbsp;There were 1324 suicides reported during 4,437,591 person years of imprisonment between 2000 and 2017 in 10 South American countries. The mean suicide rate was 40 (95% CI 16&ndash;65) per 100,000 person years for male and female genders combined. The pooled incidence rate ratio of suicide between prison and general populations was 3.9 (95% CI 3.1&ndash;5.1) for both genders combined, 2.4 (95% CI 1.9&ndash;3.1) for men and a higher ratio in women (13.5, 95% CI 6.9&ndash;26.9). High occupancies of prisons were associated with lower incidence of suicide (&beta;&thinsp;=&thinsp;&minus; 58, 95% CI &minus; 108.5 to &minus; 7.1). Conclusions:&nbsp;Suicides during imprisonment in South America are an important public health problem. Suicide prevention strategies need to target prison populations.</p
