Podcasts about dcd

DCD speaks to Dr. Tim Gregory, nuclear scientist at Sellafield, the UK's national nuclear laboratory, and author of the best-selling book Going Nuclear, about the history of nuclear power, how it actually works, and whether it can play a key role in powering the growth of AI both in the UK and further afield.

This episode is a bit different. With the festive period officially peaking, DCD decided to change tack and instead give you a "year in review," where we talk about our favorite stories from 2025. Join Charlotte Trueman, Zachary Skidmore, Georgia Butler, and Paul Lipscombe as they cover their respective beats. We hope you enjoy it - and happy holidays!

In this episode, the CardioNerds (Dr. Natalie Tapaskar, Dr. Jenna Skowronski, and Dr. Shazli Khan) discuss the process of heart transplantation from the initial donor selection to the time a patient is discharged with Dr. Dave Kaczorowski and Dr. Jason Katz. We dissect a case where we understand criteria for donor selection, the differences between DBD and DCD organ donors, the choice of vasoactive agents in the post-operative period, complications such as cardiac tamponade, and the choice of immunosuppression in the immediate post-operative period. Most importantly, we highlight the importance of multi-disciplinary teams in the care of transplant patients. Audio editing for this episode was performed by CardioNerds Intern, Dr. Julia Marques Fernandes. Enjoy this Circulation 2022 Paths to Discovery article to learn about the CardioNerds story, mission, and values.

Pearls When thinking about donor selection, you need to consider how much physiologic stress your recipient can tolerate, and this may guide your selection of “higher risk” or “lower risk” donors.   The use of DCD donors has increased the potential donor pool and shortened waitlist times with very similar perioperative outcomes to DBD transplantation.  Post-operative critical care management rests on a fundamental principle to apply as much inotropic/vasoactive therapy as needed to achieve some reasonable physiologic hemostasis, and then getting “the heck out of the way!” There are no standard regimens as practices vary across centers, but rest on providing adequate RV support, maintaining AV synchrony, and early resuscitation.   The RV is fickle and doesn't take a joke too well. RV dysfunction post-transplant is important to watch for, and it can be transient or require aggressive support. Don't miss assessing for cardiac tamponade which can require surgical evacuation- “where there's space, that space can be filled with fluid.”   Induction immunosuppression post-transplant varies across centers, but some considerations for use may include (1) high sensitization of the patient, (2) high risk immunologic donor-recipient matching, and (3) recipient renal dysfunction to provide a calcineurin inhibitor (CNI) sparing regimen long term.  Management of heart transplant patients is a multi-disciplinary effort that requires coordination amongst heart failure/transplant cardiologists, cardiac surgeons, anesthesiologists, pathology/immunologists and a slew of ancillary services. Without a dynamic and collaborative team, successful cardiac transplantation could not be possible.  Notes Notes: Notes drafted by Dr. Natalie Tapaskar  What are the basic components of donor heart selection? In practicality, it can be a very inexact science, but we use some basic selection criteria such as: (1) size matching (2) ischemic time (3) donor graft function (4) immunologic compatibility (5) age of the potential donor and recipient (6) severity of illness of the recipient (7) regional variation in donor availability When thinking about accepting older donors (>50 years old), we ideally would screen for donor coronary disease and try to keep ischemic times as short as possible. We may accept an older donor for a recipient who is highly sensitized, which leaves a smaller potential donor pool. There is no clear consensus on size matching, but the predicted heart mass is most used. We are generally more comfortable oversizing than under-sizing donor hearts. Serial echocardiography is important in potential donors as initially reduced ejection fractions can improve on repeat testing, and these organs should not be disregarded automatically. For recipients who are more surgically complex, (i.e. multiple prior sternotomies or complex anatomy), it's probably preferable to avoid older donors with some graft dysfunction and favor donors with shorter ischemic times. What is the difference between DBD and DCD? DBD is donation after brain death- these donors meet criteria for brain death. Uniform Determination of Death Act 1980: the death of an individual is The irreversible cessation of circulatory and respiratory functions or The irreversible cessation of all functions of the entire brain, including those of the brain stem DCD is donation after circulatory death- donation of the heart after confirming that circulatory function has irreversibly ceased. Only donors in category 3 of the Maastricht Classification of DCD donors are considered for DCD donations: anticipated circulatory arrest (planned withdrawal of life-support treatment). DCD hearts can be procured via direct procurement or normothermic regional perfusion (NRP). The basic difference is the way the hearts are assessed, either on an external circuit or in the donor body. For the most complex recipient, DCD may not be utilized at some centers due to concern for higher rates of delayed graft function, but this is center specific and data is still evolving. What are some features surgeons consider when procuring the donor heart? Visual assessment of the donor heart is key in DBD or NRP cases. LV function may be hard to assess, but visually the RV can be inspected. Palpation of the coronary arteries is important to assess any calcifications or abnormalities. Ventricular arrhythmias at the time of procurement may be concerning. Key considerations in the procurement process: (1) Ensuring the heart remains decompressed at all times and doesn't become distended (2) adequate cardioplegia delivery (3) aorta is cross-clamped properly all the way across the vessel (4) avoiding injury to adjacent structures during procurement What hemodynamic parameters should we monitor and what vasoactive agents are used peri-heart transplant? There is no consensus regarding vasoactive agent use post-transplant and practice varies across institutions. Some commonly seen regimens may include: (1) AAI pacing around 110 bpm to support RV function and preserve AV synchrony (2) inotropic agents such as epinephrine and dobutamine to support RV function (3) pulmonary vasodilators such as inhaled nitric oxide to optimize RV afterload Early post-transplant patients tend to have low cardiac filling pressures and require preload monitoring and resuscitation initially. Slow weaning of inotropes as the patient shows signs of stable graft function and hemodynamics. RV dysfunction may manifest as elevated central venous pressure with low cardiac index or hypotension with reducing urine output. Optimize inotropic support, volume status, metabolic status (acidosis and hypoxia), afterload (pulmonary hypertension), and assess for cardiac tamponade. Tamponade requires urgent take-back to the operating room to evacuate material. Refractory RV failure requires mechanical circulatory support, with early consideration of VA-ECMO. Isolated RV MCS may be used in the right clinical context. Why do pericardial effusions/cardiac tamponade happen after transplant? They are not uncommon after transplant and can be due to: Inherent size differences between the donor and recipient (i.e. if the donor heart is much smaller than the recipient's original heart) Bleeding from suture lines and anastomoses, pacing wires, and cannulation sites Depending on the hemodynamic stability of the patient and the location of the effusion, these effusions may require urgent return to the OR for drainage/clot evacuation via reopening the sternotomy, mini thoracotomy, and possible pericardial windows. What are the basics of immunosuppression post-transplant? Induction immunosuppression is variably used and is center-specific. Considerations for using induction therapy may include: (1) high sensitization of the patient (2) younger patients or multiparous women with theoretically more robust immune systems (3) crossing of recipient antibodies with donor antigens (3) renal function to provide a CNI sparing regimen long term Some considerations for avoiding induction may include: (1) older age of the recipient (2) underlying comorbid conditions such as infections or frailty of the recipient What are expected activity restrictions post-transplant? Sternal precautions are important to maintain sternal wire integrity. Generally avoiding lifting >10 pounds in the first 4-12 weeks, no driving usually in the first 4 weeks, monitoring for signs and symptoms of wound infections, and optimizing nutrition and physical activity. Cardiac rehabilitation is incredibly important as soon as feasible. References Kharawala A , Nagraj S , Seo J , et al.

A inteligência artificial, em seus múltiplos sentidos, tem dominado a agenda pública e até mesmo o direcionamento do capital das grandes empresas de tecnologia. Mas você já parou para pensar na infraestrutura gigantesca que dê conta de sustentar o crescimento acelerado das IAs? O futuro e o presente da inteligência artificial passa pela existência dos datacenters. E agora é mais urgente que nunca a gente discutir esse assunto. Estamos vendo um movimento se concretizar, que parece mais uma forma de colonialismo digital: com a crescente resistência à construção de datacenters nos países no norte global, empresas e governos parecem estar convencidos a trazer essas infraestruturas imensas com todos os seus impactos negativos ao sul global. Nesse episódio Yama Chiodi e Damny Laya conversam com pesquisadores, ativistas e atingidos para tentar aprofundar o debate sobre a infraestrutura material das IAs. A gente conversa sobre o que são datacenters e como eles impactam e irão impactar nossas vidas. No segundo episódio, recuperamos movimentos de resistência a sua instalação no Brasil e como nosso país se insere no debate, seguindo a perspectiva de ativistas e de pesquisadores da área que estão buscando uma regulação mais justa para esses grandes empreendimentos.  ______________________________________________________________________________________________ ROTEIRO [ vinheta da série ] [ Começa bio-unit ] YAMA: A inteligência artificial, em seus múltiplos sentidos, tem dominado a agenda pública e até mesmo o direcionamento do capital das grandes empresas de tecnologia. Mas você já parou para pensar na infraestrutura gigantesca que dê conta de sustentar o crescimento acelerado das IA? DAMNY: O futuro e o presente da inteligência artificial passa pela existência dos data centers. E agora é mais urgente que nunca a gente discutir esse assunto. Estamos vendo um movimento se concretizar, que parece mais uma forma de colonialismo digital: com a crescente resistência à construção de datacenters nos países no norte global, empresas e governos parecem estar convencidos a trazer os datacenters com todos os seus impactos negativos ao sul global. YAMA: Nós conversamos com pesquisadores, ativistas e atingidos e em dois episódios nós vamos tentar aprofundar o debate sobre a infraestrutura material das IAs. No primeiro, a gente conversa sobre o que são datacenters e como eles impactam e irão impactar nossas vidas. DAMNY: No segundo, recuperamos movimentos de resistência a sua instalação no Brasil e como nosso país se insere no debate, seguindo a perspectiva de ativistas e de pesquisadores da área que estão buscando uma regulação mais justa para esses grandes empreendimentos. [ tom baixo ] YAMA: Eu sou o Yama Chiodi, jornalista de ciência e pesquisador do campo das mudanças climáticas. Se você já é ouvinte do oxigênio pode ter me ouvido aqui na série cidade de ferro ou no episódio sobre antropoceno. Ao longo dos últimos meses investiguei os impactos ambientais das inteligências artificiais para um projeto comum entre o LABMEM, o laboratório de mudança tecnológica, energia e meio ambiente, e o oxigênio. Em setembro passado, o Damny se juntou a mim pra gente construir esses episódios juntos. E não por acaso. O Damny publicou em outubro passado um relatório sobre os impactos socioambientais dos data centers no Brasil, intitulado “Não somos quintal de data center”. O link para o relatório completo se encontra disponível na descrição do episódio. Bem-vindo ao Oxigênio, Dam. DAMNY: Oi Yama. Obrigado pelo convite pra construir junto esses episódios. YAMA: É um prazer, meu amigo. DAMNY: Eu também atuo como jornalista de ciência e sou pesquisador de governança da internet já há algum tempo. Estou agora trabalhando como jornalista e pesquisador aqui no LABJOR, mas quando escrevi o relatório eu tava trabalhando como pesquisador-consultor na ONG IDEC, Instituto de Defesa de Consumidores. YAMA: A gente começa depois da vinheta. [ Termina Bio Unit] [ Vinheta Oxigênio ] [ Começa Documentary] YAMA: Você já deve ter ouvido na cobertura midiática sobre datacenters a formulação que te diz quantos litros de água cada pergunta ao chatGPT gasta. Mas a gente aqui não gosta muito dessa abordagem. Entre outros motivos, porque ela reduz o problema dos impactos socioambientais das IA a uma questão de consumo individual. E isso é um erro tanto político como factual. Calcular quanta água gasta cada pergunta feita ao ChatGPT tira a responsabilidade das empresas e a transfere aos usuários, escondendo a verdadeira escala do problema. Mesmo que o consumo individual cresça de modo acelerado e explosivo, ele sempre vai ser uma pequena fração do problema. Data centers operam em escala industrial, computando quantidades incríveis de dados para treinar modelos e outros serviços corporativos. Um único empreendimento pode consumir em um dia mais energia do que as cidades que os abrigam consomem ao longo de um mês. DAMNY: Nos habituamos a imaginar a inteligência artificial como uma “nuvem” etérea, mas, na verdade, ela só existe a partir de data centers monstruosos que consomem quantidades absurdas de recursos naturais. Os impactos sociais e ambientais são severos. Data centers são máquinas de consumo de energia, água e terra, e criam poluição do ar e sonora, num modelo que reforça velhos padrões de racismo ambiental. O desenvolvimento dessas infraestruturas frequentemente acontece à margem das comunidades afetadas, refazendo a cartilha global da injustiça ambiental. Ao seguir suas redes, perceberemos seus impactos em rios, no solo, no ar, em territórios indígenas e no crescente aumento da demanda por minerais críticos e, por consequência, de práticas minerárias profundamente destrutivas. YAMA: De acordo com a pesquisadora Tamara Kneese, diretora do programa de Clima, Tecnologia e Justiça do instituto de pesquisa Data & Society, com quem conversamos, essa infraestrutura está criando uma nova forma de colonialismo tecnológico. Os danos ambientais são frequentemente direcionados para as comunidades mais vulneráveis, de zonas rurais às periferias dos grandes centros urbanos, que se tornam zonas de sacrifício para o progresso dessa indústria. DAMNY: Além disso, a crescente insatisfação das comunidades do Norte Global com os data centers tem provocado o efeito colonial de uma terceirização dessas estruturas para o Sul Global. E o Brasil não apenas não é exceção como parece ser um destino preferencial por sua alta oferta de energia limpa. [pausa] E com o aval do governo federal, que acaba de publicar uma medida provisória chamada REDATA, cujo objetivo é atrair data centers ao Brasil com isenção fiscal e pouquíssimas responsabilidades. [ Termina Documentary] [tom baixo ] VOICE OVER: BLOCO 1 – O QUE SÃO DATA CENTERS? YAMA: Pra entender o que são data centers, a gente precisa antes de tudo de entender que a inteligência artificial não é meramente uma nuvem etérea que só existe virtualmente. Foi assim que a gente começou nossa conversa com a pesquisadora estadunidense Tamara Kneese. Ela é diretora do programa de Clima, Tecnologia e Justiça do instituto de pesquisa Data & Society. TAMARA: PT – BR [ Eu acho que o problema da nossa relação com a computação é que a maioria parte do tempo a gente não pensa muito sobre a materialidade dos sistemas informacionais e na cadeia de suprimentos que permitem que eles existam. Tudo que a gente faz online não depende só dos nossos aparelhos, ou dos serviços de nuvem que a gente contrata, mas de uma cadeia muito maior. De onde ver o hardware que a gente usa? Que práticas de trabalho são empregadas nessa cadeia? E então, voltando à cadeia de suprimentos, pensar sobre os materiais brutos e os minerais críticos e outras formas de extração, abusos de direitos humanos e trabalhistas que estão diretamente relacionados à produção dos materiais que precisamos pra computação em geral. ] So I think, you know, the problem with our relationship to computing is that, most of the time, we don’t really think that much about the materiality of the computing system and the larger supply chain. You know, thinking about the fact that, of course, everything we do relies not just on our own device, or the particular cloud services that we subscribe to, but also on a much larger supply chain. So, where does the hardware come from, that we are using, and what kind of labor practices are going into that? And then be, you know, further back in the supply chain, thinking about raw materials and critical minerals and other forms of extraction, and human rights abuses and labor abuses that also go into the production of the raw materials that we need for computing in general. DAMNY: A Tamara já escreveu bastante sobre como a metáfora da nuvem nos engana, porque ela dificulta que a gente enxergue a cadeia completa que envolve o processamento de tantos dados. E isso se tornou uma questão muito maior com a criação dos chatbots e das IAs generativas. YAMA: Se a pandemia já representou uma virada no aumento da necessidade de processamento de dados, quando passamos a ir à escola e ao trabalho pelo computador, o boom das IA generativas criou um aumento sem precedentes da necessidade de expandir essas cadeias. DAMNY: E na ponta da infraestrutura de todas as nuvens estão os data centers. Mais do que gerar enormes impactos sócio-ambientais, eles são as melhores formas de enxergar que o ritmo atual da expansão das IAs não poderá continuar por muito tempo, por limitações físicas. Não há terra nem recursos naturais que deem conta disso. YAMA: A gente conversou com a Cynthia Picolo, que é Diretora Executiva do LAPIN, o Laboratório de Políticas Públicas e Internet. O LAPIN tem atuado muito contra a violação de direitos na implementação de data centers no Brasil e a gente ainda vai conversar mais sobre isso. DAMNY: Uma das coisas que a Cynthia nos ajudou a entender é como não podemos dissociar as IAs dos data centers. CYNTHIA: Existe uma materialidade por trás. Existe uma infraestrutura física, que são os data centers. Então os data centers são essas grandes estruturas que são capazes de armazenar, processar e transferir esses dados, que são os dados que são os processamentos que vão fazer com que a inteligência artificial possa acontecer, possa se desenvolver, então não existe sem o outro. Então falar de IA é falar de Datacenter. Então não tem como desassociar. YAMA: Mas como é um datacenter? A Tamara descreve o que podemos ver em fotos e vídeos na internet. TAMARA: [ Sim, de modo geral, podemos dizer que os data centers são galpões gigantes de chips, servidores, sistemas em redes e quando você olha pra eles, são todos muitos parecidos, prédios quadrados sem nada muito interessante. Talvez você nem saiba que é um data center se não observar as luzes e perceber que é uma estrutura enorme sem pessoas, sem trabalhadores. ] Yeah, so, you know, essentially, they’re like giant warehouses of chips, of servers, of networked systems, and, you know, they look like basically nondescript square buildings, very similar. And you wouldn’t really know that it’s a data center unless you look at the lighting, and you kind of realize that something… like, it’s not inhabited by people or workers, really. DAMNY: No próximo bloco a gente tenta resumir os principais problemas socioambientais que os data centers já causam e irão causar com muita mais intensidade no futuro. [tom baixo ] VOICE OVER: BLOCO 2 – A ENORME LISTA DE PROBLEMAS YAMA: O consumo de energia é provavelmente o problema mais conhecido dos data centers e das IAs. Segundo dados da Agência Internacional de Energia, a IEA, organização internacional da qual o Brasil faz parte, a estimativa para o ano de 2024 é que os data centers consumiram cerca de 415 TWh. A cargo de comparação, segundo a Empresa de Pesquisa Energética, instituto de pesquisa público associado ao Ministério das Minas e Energia, o Brasil consumiu no ano de 2024 cerca de 600 TWh. DAMNY: Segundo o mesmo relatório da Agência Internacional de Energia, a estimativa é que o consumo de energia elétrica por datacenters em 2030 vai ser de pelo menos 945 TWh, o que representaria 3% de todo consumo global projetado. Quando a gente olha pras estimativas de outras fontes, contudo, podemos dizer que essas são projeções até conservadoras. Especialmente considerando o impacto da popularização das chamadas LLM, ou grandes modelos de linguagem – aqueles YAMA: Ou seja, mesmo com projeções conservadoras, os data centers do mundo consumiriam em 2030, daqui a menos de cinco anos, cerca de 50% a mais de energia que o Brasil inteiro consome hoje. Segundo a IEA, em 2030 o consumo global de energia elétrica por data centers deve ser equivalente ao consumo da Índia, o país mais populoso do mundo. E há situações locais ainda mais precárias. DAMNY: É o caso da Irlanda. Segundo reportagem do New York Times publicada em outubro passado, espera-se que o consumo de energia elétrica por data centers por lá represente pelo menos 30% do consumo total do país nos próximos anos. Mas porquê os datacenters consomem tanta energia? TAMARA: [ Então, particularmente com o tipo de IA que as empresas estão investindo agora, há uma necessidade de chips e GPUs muito mais poderosos, de modo que os data centers também são sobre prover energia o suficiente pra todo esse poder computacional que demandam o treinamento e uso de grandes modelos de linguagem. Os data centers são estruturas incrivelmente demandantes de energia e água. A água em geral serve para resfriar os servidores, então tem um número considerável de sistemas de cooling que usam água. Além disso tudo, você também precisa de fontes alternativas de energia, porque algumas vezes, uma infraestrutura tão demandante de energia precisa recorrer a geradores para garantir que o data center continue funcionando caso haja algum problema na rede elétrica. ] So, you know, particularly with the kinds of AI that companies are investing in right now, there’s a need for more powerful chips, GPUs, and so Data centers are also about providing enough energy and computational power for these powerful language models to be trained and then used. And so the data center also, you know, in part because it does require so much energy, and it’s just this incredibly energy-intensive thing, you also need water. And the water comes from having to cool the servers, and so… So there are a number of different cooling systems that use water. And then on top of that, you also need backup energy sources, so sometimes, because there’s such a draw on the power grid, you have to have backup generators to make sure that the data center can keep going if something happens with the grid. YAMA: E aqui a gente começa a entender o tamanho do problema. Os data centers são muitas vezes construídos em lugares que já sofrem com infraestruturas precárias de eletricidade e com a falta de água potável. Então eles criam problemas de escassez onde não havia e aprofundam essa escassez em locais onde isso já era uma grande questão – como a região metropolitana de Fortaleza sobre a qual falaremos no próximo episódio, que está em vias de receber um enorme data center do Tiktok. DAMNY: É o que também relatam os moradores de Querétaro, no México, que vivem na região dos data centers da Microsoft. A operação dos data centers da Microsoft gerou uma crise sem precedentes, com quedas frequentes de energia e o interrompimento do abastecimento de água que muitas vezes duram semanas. Os data-centers impactaram de tal forma as comunidades que escolas cancelaram aulas e, indiretamente, foram responsáveis por uma crise de gastroenterite entre crianças. YAMA: E isso nos leva pro segundo ponto. O consumo de água, minerais críticos e outros recursos naturais. TAMARA: [O problema da energia tem recebido mais atenção, porque é uma fonte de ansiedade também. Pensar sobre o aumento da demanda de energia em tempos em que supostamente estaríamos transicionando para deixar de usar energias fósseis, o que obviamente pode ter efeitos devastadores. Mas eu acredito que num nível mais local, o consumo de água é mais relevante. Nós temos grandes empresas indo às áreas rurais do México, por exemplo, e usando toda a água disponível e basicamente deixando as pessoas sem água. E isso é incrivelmente problemático. Então isso acontece em áreas que já tem problemas de abastecimento de água, onde as pessoas já não tem muito poder de negociação com as empresas. Não têm poder político pra isso. São lugares tratados como zonas de sacrifício, algo que já vimos muitas vezes no mundo, especialmente em territórios indígenas. Então as consequências são na verdade muito maiores do que só problemas relacionados à energia. ] I think the energy problem has probably gotten the most attention, just because it is a source of anxiety, too, so thinking about, you know, energy demand at a time when we’re supposed to be transitioning away from fossil fuels. And clearly, the effects that that can have will be devastating. But I think on a local level, things like the water consumption can matter more. So, you know, if we have tech companies moving into rural areas in Mexico and, you know, using up all of their water and basically preventing people in the town from having access to water. That is incredibly problematic. So I think, you know, in water-stressed areas and areas where the people living in a place don’t have as much negotiating power with the company. Don’t have as much political power, and especially if places are basically already treated as sacrifice zones, which we’ve seen repeatedly many places in the world, with Indigenous land in particular, you know, I think the consequences may go far beyond just thinking about, you know, the immediate kind of energy-related problems. YAMA: Existem pelo menos quatro fins que tornam os data centers máquinas de consumir água. O mais direto e local é a água utilizada na refrigeração de todo equipamento que ganha temperatura nas atividades de computação, o processo conhecido como cooling. Essa prática frequentemente utiliza água potável. Apesar de já ser extremamente relevante do ponto de vista de consumo, essa é apenas uma das formas de consumo abundante de água. DAMNY: Indiretamente, os data centers também consomem a água relacionada ao seu alto consumo de energia, em especial na geração de energia elétrica em usinas hidrelétricas e termelétricas. Também atrelada ao consumo energético, está o uso nas estações de tratamento de água, que visam tratar a água com resíduos gerada pelo data center para tentar reduzir a quantidade de água limpa utilizada. YAMA: Por fim, a cadeia de suprimentos de chips e servidores que compõem os data centers requer água ultrapura e gera resíduos químicos. Ainda que se saiba que esse fator gera gastos de água e emissões de carbono relevantes, os dados são super obscuros, entre outros motivos, porque a maioria dos dados que temos sobre o consumo de água em data centers são fornecidos pelas próprias empresas. CYNTHIA: A água e os minérios são componentes também basilares para as estruturas de datacenter, que são basilares para o funcionamento da inteligência artificial. (…). E tem toda uma questão, como eu disse muitas vezes, captura um volume gigante de água doce. E essa água que é retornada para o ecossistema, muitas vezes não é compensada da água que foi capturada. Só que as empresas também têm uma promessa em alguns relatórios, você vai ver que elas têm uma promessa até de chegar em algum ponto para devolver cento e vinte por cento da água. Então a empresa está se comprometendo a devolver mais água do que ela capturou. Só que a realidade é o quê? É outra. Então, a Google, por exemplo, nos últimos cinco anos, reportou um aumento de cento e setenta e sete por cento do uso de água. A Microsoft mais trinta e oito e a Amazon sequer reporta o volume de consumo de água. Então uma lacuna tremenda para uma empresa desse porte, considerando todo o setor de Data centers. Mas tem toda essa questão da água, que é muito preocupante, não só por capturar e o tratamento dela e como ela volta para o meio ambiente, mas porque há essa disputa também com territórios que têm uma subsistência muito específica de recursos naturais, então existe uma disputa aí por esse recurso natural entre comunidade e empreendimento. DAMNY: Nessa fala da Cynthia a gente observa duas coisas importantes: a primeira é que não existe data center sem água para resfriamento, de modo que o impacto local da instalação de um empreendimento desses é uma certeza irrefutável. E é um dano contínuo. Enquanto ele estiver em operação ele precisará da água. É como se uma cidade de grande porte chegasse de repente, demandando uma quantidade de água e energia que o local simplesmente não tem para oferecer. E na hora de escolher entre as pessoas e empreendimentos multimilionários, adivinha quem fica sem água e com a energia mais cara? YAMA: A segunda coisa importante que a Cynthia fala é quando ela nos chama a atenção sobre a demanda por recursos naturais. Nós sabemos que recursos naturais são escassos. Mais do que isso, recursos naturais advindos da mineração têm a sua própria forma de impactos sociais e ambientais, o que vemos frequentemente na Amazônia brasileira. O que acontecerá com os data centers quando os recursos naturais locais já não forem suficientes para seu melhor funcionamento? Diante de uma computação que passa por constante renovação pela velocidade da obsolescência, o que acontece com o grande volume de lixo eletrônico gerado por data centers? Perguntas que não têm resposta. DAMNY: A crise geopolítica em torno dos minerais conhecidos como terra-rara mostra a complexidade política e ambiental do futuro das IA do ponto de vista material e das suas cadeias de suprimento. No estudo feito pelo LAPIN, a Cynthia nos disse que considera que esse ponto do aumento da demanda por minerais críticos que as IA causam é um dos pontos mais opacos nas comunicações das grandes empresas de tecnologia sobre o impacto de seus data centers. CYNTHIA: E outro ponto de muita, muita lacuna, que eu acho que do nosso mapeamento, desses termos mais de recursos naturais. A cadeia de extração mineral foi o que mais foi opaco, porque, basicamente, as empresas não reportam nada sobre essa extração mineral e é muito crítico, porque a gente sabe que muitos minérios vêm também de zonas de conflito. Então as grandes empresas, pelo menos as três que a gente mapeou, elas têm ali um trechinho sobre uma prestação de contas da cadeia mineral. Tudo que elas fazem é falar que elas seguem um framework específico da OCDE sobre responsabilização. YAMA: Quando as empresas falam de usar energias limpas e de reciclar a água utilizada, eles estão se desvencilhando das responsabilidades sobre seus datacenters. Energia limpa não quer dizer ausência de impacto ambiental. Pras grandes empresas, as fontes de energia limpa servem para gerar excedente e não para substituir de fato energias fósseis. Você pode ter um data center usando majoritariamente energia solar no futuro, mas isso não muda o fato de que ele precisa funcionar 24/7 e as baterias e os geradores a diesel estarão sempre lá. Além disso, usinas de reciclagem de água, fazendas de energia solar e usinas eólicas também têm impactos socioambientais importantes. O uso de recursos verdes complexifica o problema de identificar os impactos locais e responsabilidades dos data centers, mas não resolve de nenhuma forma os problemas de infraestrutura e de fornecimento de água e energia causados pelos empreendimentos. DAMNY: É por isso que a gente alerta pra não comprar tão facilmente a história de que cada pergunta pro chatGPT gasta x litros de água. Se você não perguntar nada pro chatGPT hoje, ou se fizer 1000 perguntas, não vai mudar em absolutamente nada o alto consumo de água e os impactos locais destrutivos dos data centers que estão sendo instalados a todo vapor em toda a América Latina. A quantidade de dados e de computação que uma big tech usa para treinar seus modelos, por exemplo, jamais poderá ser equiparada ao consumo individual de chatbots. É como comparar as campanhas que te pedem pra fechar a torneira ao escovar os dentes, enquanto o agro gasta em minutos água que você não vai gastar na sua vida inteira. Em resumo, empresas como Google, Microsoft, Meta e Amazon só se responsabilizam pelos impactos diretamente causados por seus data centers e, mesmo assim, é uma responsabilização muito entre aspas, à base de greenwashing. Você já ouviu falar de greenwashing? CYNTHIA: Essa expressão em inglês nada mais é do que a tradução literal, que é o discurso verde. (…)É justamente o que a gente está conversando. É justamente quando uma empresa finge se preocupar com o meio ambiente para parecer sustentável, mas, na prática, as ações delas não trazem esses benefícios reais e, pelo contrário, às vezes trazem até danos para o meio ambiente. Então, na verdade, é uma forma até de manipular, ou até mesmo enganar as pessoas, os usuários daqueles sistemas ou serviços com discursos e campanhas com esses selos verdes, mas sem comprovar na prática. YAMA: Nesse contexto, se torna primordial que a gente tenha mais consciência de toda a infraestrutura material que está por trás da inteligência artificial. Como nos resumiu bem a Tamara: TAMARA: [ Eu acredito que ter noção da infraestrutura completa que envolve a cadeia da IA realmente ajuda a entender a situação. Mesmo que você esteja usando, supostamente, energia renovável para construir e operar um data center, você ainda vai precisar de muitos outros materiais, chips, minerais e outras coisas com suas próprias cadeias de suprimento. Ou seja, independente da forma de energia utilizada, você ainda vai causar dano às comunidades e destruição ambiental. ] But that… I think that is why having a sense of the entire AI supply chain is really helpful, just in terms of thinking about, you know, even if you’re, in theory, using renewable energy to build a data center, you still are relying on a lot of other materials, including chips, including minerals, and other things that. (…) We’re still, you know, possibly going to be harming communities and causing environmental disruption. [ tom baixo ] YAMA: Antes de a gente seguir pro último bloco, eu queria só dizer que a entrevista completa com a Dra. Tamara Kneese foi bem mais longa e publicada na íntegra no blog do GEICT. O link para a entrevista tá na descrição do episódio, mas se você preferir pode ir direto no bloco do GEICT. [ tom baixo ] VOICE OVER: BLOCO 3 – PROBLEMAS GLOBAIS, PROBLEMAS LOCAIS YAMA: Mesmo conhecendo as cadeias, as estratégias de greenwashing trazem um grande problema à tona, que é uma espécie de terceirização das responsabilidades. As empresas trazem medidas compensatórias que não diminuem em nada o impacto local dos seus data centers. Então tem uma classe de impactos que são globais, como as emissões de carbono e o aumento da demanda por minerais críticos, por exemplo. E globais no sentido de que eles são parte relevante dos impactos dos data centers, mas não estão impactando exatamente nos locais onde foram construídos. CYNTHIA: Google, por exemplo, nesse recorte que a gente fez da pesquisa dos últimos cinco anos, ela simplesmente reportou um aumento de emissão de carbono em setenta e três por cento. Não é pouca coisa. A Microsoft aumentou no escopo dois, que são as emissões indiretas, muito por conta de data centers, porque tem uma diferenciação por escopo, quando a gente fala de emissão de gases, a Microsoft, nesse período de cinco anos, ela quadruplicou o tanto que ela tem emitido. A Amazon aumentou mais de trinta por cento. Então a prática está mostrando que essas promessas estão muito longe de serem atingidas. Só que aí entra um contexto mais de narrativa. Por que elas têm falado e prometido a neutralidade de carbono? Porque há um mecanismo de compensação. (…) Então elas falam que estão correndo, correndo para atingir essa meta de neutralidade de carbono, mas muito por conta dos instrumentos de compensação, compensação ou de crédito de carbono ou, enfim, para uso de energias renováveis. Então se compra esse certificado, se fazem esses contratos, mas, na verdade, não está tendo uma redução de emissão. Está tendo uma compensação. (…) Essa compensação é um mecanismo financeiro, no final do dia. Porque, quando você, enquanto empresa, trabalha na compensação dos seus impactos ambientais e instrumentos contratuais, você está ignorando o impacto local. Então, se eu estou emitindo impactando aqui o Brasil, e estou comprando crédito de carbono em projetos em outra área, o impacto local do meu empreendimento está sendo ignorado. YAMA: E os impactos materiais locais continuam extremamente relevantes. Além do impacto nas infraestruturas locais de energia e de água sobre as quais a gente já falou, há muitas reclamações sobre a poluição do ar gerada pelos geradores, as luzes que nunca desligam e até mesmo a poluição sonora. A Tamara nos contou de um caso curioso de um surto de distúrbios de sono e de enxaqueca que tomou regiões de data centers nos Estados Unidos. TAMARA: [ Uma outra coisa que vale ser lembrada: as pessoas que vivem perto dos data centers tem nos contado que eles são super barulhentos, eles também relatam a poluição visual causada pelas luzes e a poluição sonora. Foi interessante ouvir de comunidades próximas a data centers de mineração de criptomoedas, por exemplo, que os moradores começaram a ter enxaquecas e distúrbios de sono por viverem próximos das instalações. E além de tudo isso, ainda tem a questão da poluição do ar, que é visível a olho nu. Há muitas partículas no ar onde há geradores movidos a diesel para garantir que a energia esteja sempre disponível. ] And the other thing is, you know, for people who live near them, they’re very loud, and so if you talk to people who live near data centers, they will talk about the light pollution, the noise pollution. And it’s been interesting, too, to hear from communities that are near crypto mining facilities, because they will complain of things like migraine headaches and sleep deprivation from living near the facilities. And, you know, the other thing is that the air pollution is quite noticeable. So there’s a lot of particulate matter, particularly in the case of using diesel-fueled backup generators as an energy stopgap. DAMNY: E do ponto de vista dos impactos locais, há um fator importantíssimo que não pode ser esquecido: território. Data centers podem ser gigantes, mas ocupam muito mais espaço que meramente seus prédios, porque sua cadeia de suprimentos demanda isso. Como a água e a energia chegarão até os prédios? Mesmo que sejam usados fontes renováveis de energia, onde serão instaladas as fazendas de energia solar ou as usinas de energia eólica e de tratamento de água? Onde a água contaminada e/ou tratada será descartada? Quem vai fiscalizar? YAMA: E essa demanda sem fim por território esbarra justamente nas questões de racismo ambiental. Porque os territórios que são sacrificados para que os empreendimentos possam funcionar, muito frequentemente, são onde vivem povos originários e populações marginalizadas. Aqui percebemos que a resistência local contra a instalação de data centers é, antes de qualquer coisa, uma questão de justiça ambiental. É o caso de South Memphis nos Estados Unidos, por exemplo. TAMARA: [ Pensando particularmente sobre os tipos de danos causados pelos data centers, não é somente a questão da conta de energia ficar mais cara, ou quantificar a quantidade de energia e água gasta por data centers específicos. A verdadeira questão, na minha opinião, é a relação que existe entre esses danos socioambientais, danos algorítmicos e o racismo ambiental e outras formas de impacto às comunidades que lidam com isso a nível local. Especialmente nos Estados Unidos, com todo esse histórico de supremacia branca e a falta de direitos civis, não é coincidência que locais onde estão comunidades negras, por exemplo, sejam escolhidos como zonas de sacrifício. As comunidades negras foram historicamente preferenciais para todo tipo de empreendimento que demanda sacrificar território, como estradas interestaduais, galpões da Amazon… quer dizer, os data centers são apenas a continuação dessa política histórica de racismo ambiental. E tudo isso se soma aos péssimos acordos feitos a nível local, onde um prefeito e outras lideranças governamentais pensam que estão recebendo algo de grande valor econômico. Em South Memphis, por exemplo, o data center é da xAI. Então você para pra refletir como essa plataforma incrivelmente racista ainda tem a audácia de poluir terras de comunidades negras ainda mais ] I think, the way of framing particular kinds of harm, so, you know, it’s not just about, you know, people’s energy bills going up, or, thinking about how we quantify the energy use or the water use of particular data centers, but really thinking about the relationship between a lot of those social harms and algorithmic harms and the environmental racism and other forms of embodied harms that communities are dealing with on that hyper-local level. And, you know, in this country, with its history of white supremacy and just general lack of civil rights, you know, a lot of the places where Black communities have traditionally been, tend to be, you know, the ones sacrificed for various types of development, like, you know, putting up interstates, putting up warehouses for Amazon and data centers are just a continuation of the what was already happening. And then you have a lot of crooked deals on the local level, where, you know, maybe a mayor and other local officials think that they’re getting something economically of value. In South Memphis, the data center is connected to x AI. And so thinking about this platform that is so racist and so incredibly harmful to Black communities, you know, anyway, and then has the audacity to actually pollute their land even more. DAMNY: Entrando na questão do racismo ambiental a gente se encaminha para o nosso segundo episódio, onde vamos tentar entender como o Brasil se insere na questão dos data centers e como diferentes setores da população estão se organizando para resistir. Antes de encerrar esse episódio, contudo, a gente traz brevemente pra conversa dois personagens que vão ser centrais no próximo episódio. YAMA: Eles nos ajudam a compreender como precisamos considerar a questão dos territórios ao avaliar os impactos. Uma dessas pessoas é a Andrea Camurça, do Instituto Terramar, que está lutando junto ao povo Anacé pelo direito de serem consultados sobre a construção de um data center do TIKTOK em seus territórios. Eu trago agora um trechinho dela falando sobre como mesmo medidas supostamente renováveis se tornam violações territoriais num contexto de racismo ambiental. ANDREA: A gente recebeu notícias agora, recentemente, inclusive ontem, que está previsto um mega empreendimento solar que vai ocupar isso mais para a região do Jaguaribe, que vai ocupar, em média, de equivalente a seiscentos campos de futebol. Então, o que isso representa é a perda de terra. É a perda de água. É a perda do território. É uma diversidade de danos aos povos e comunidades tradicionais que não são reconhecidos, são invisibilizados. Então é vendido como território sem gente, sendo que essas energias chegam dessa forma. Então, assim a gente precisa discutir sobre energias renováveis. A gente precisa discutir sobre soberania energética. A gente precisa discutir sobre soberania digital, sim, mas construída a partir da necessidade do local da soberania dessas populações. DAMNY: A outra pessoa que eu mencionei é uma liderança Indígena, o cacique Roberto Anacé. Fazendo uma ótima conexão que nos ajuda a perceber como os impactos globais e locais dos data centers estão conectados, ele observa como parecemos entrar num novo momento do colonialismo, onde a soberania digital e ambiental do Brasil volta a estar em risco, indo de encontro à violação de terras indígenas. CACIQUE ROBERTO: Há um risco para a questão da biodiversidade, da própria natureza da retirada da água, do aumento de energia, mas também não somente para o território da Serra, mas para todos que fazem uso dos dados. Ou quem expõe esses dados. Ninguém sabe da mão de quem vai ficar, quem vai controlar quem vai ordenar? E para que querem essa colonização? Eu chamo assim que é a forma que a gente tem essa colonização de dados. Acredito eu que a invasão do Brasil em mil e quinhentos foi de uma forma. Agora nós temos a invasão de nossas vidas, não somente para os indígenas, mas de todos, muitas vezes que fala muito bem, mas não sabe o que vai acontecer depois que esses dados estão guardados. Depois que esses dados vão ser utilizados, para que vão ser utilizados, então esses agravos. Ele é para além do território indígena na série.

In this episode, the CardioNerds (Dr. Rachel Goodman, Dr. Shazli Khan, and Dr. Jenna Skowronski) discuss a case of AMI-shock with a focus on listing for heart transplant with faculty expert Dr. Kelly Schlendorf. We dive into the world of pre-transplant management, discuss the current allocation system, and additional factors that impact transplant timing, such as sensitization. We conclude by discussing efforts to increase the donor pool.  Audio editing for this episode was performed by CardioNerds Intern, Julia Marques Fernandes.

Pearls The current iteration of heart allocation listing is based on priority, with status 1 being the highest priority.  The are multiple donor and recipient characteristics to consider when listing a patient for heart transplantation and accepting a heart offer.  Desensitization is an option for patients who need heart transplantation but are highly sensitized.  Protocols vary by center.  Acceptance of DCD hearts is one of many efforts to expand the donor pool   Notes Notes: Notes drafted by Dr. Rachel Goodman  Once a patient is determined to be a candidate for heart transplantation, how is priority determined?  The current iteration of heart listing statuses was implemented in 2018.  Priority is determined by acuity, with higher statuses indicating higher acuity and given higher priority.  Status 1 is the highest priority status, and Status 7 is inactive patients. (1,2)  What criteria should be considered in organ selection when listing a patient for heart transplant?  Once it is determined that a patient will be listed for heart transplantation, there are certain criteria that should be assessed.  These factors may impact pre-transplant care and/or donor matching (3).  (1) PVR  (2) Height/weight   (3) Milage listing criteria  (4) Blood typing/cPRA/HLA typing  What is desensitization and why would it be considered?  Desensitization is an attempt to reduce or remove anti-HLA antibodies in the recipient.  It is done to increase the donor pool.  In general, desensitization is reserved for patients who are highly sensitized.  Desensitization protocols vary by transplant center, and some may opt against it.  When considering desensitization, it is important to note two key things: first, there is no promise that it will work, and second desensitization involves the use of immunosuppressive agents, thereby putting patients at increased risk of infection and cytopenia. (4)  Can you explain DCD and DBD transplant?  DBD: donor that have met the requirements for legal definition of brain death.   DCD: donors that have not met the legal definition of brain death but have been determined to have circulatory death.  Because the brain death criteria have not been met, organ recovery can only take place once death is confirmed based on cessation of circulatory and respiratory function. Life support is only withdrawn following declaration of circulatory death—once the heart has stopped beating and spontaneous respirations have stopped.

AtlasEdge emerged in 2021 after Liberty Global and Digital Bridge combined their European assets to make an “Edge” data center player on the continent. Initially, the company targeted smaller data centers - previously positing 4-6MW as the largest it would deploy when talking to DCD, but things have changed. The world has changed. Durvasula was hired in May 2024 and has since been leading the company through the new era, one where it's embracing larger facilities that before, and that's for one simple reason: AI. We discuss the changing strategy and what AtlasEdge looks like today.

This week's episode is a special cross-over with CMDA's Voice of Advocacy podcast, hosted by Dr. Brick Lantz, CMDA's Vice President of Advocacy and Bioethics. Joined by Dr. Gary Ott, a renowned cardiac transplant surgeon at Providence Heart and Vascular Clinic, they explore the ethical boundaries of life, death, and medical innovation – examining how we define death in the ICU era, the differences between brain death and donation after circulatory death (DCD), and how emerging technologies like “heart-in-a-box” systems and normothermic regional perfusion (NRP) are reshaping transplant medicine. With decades of experience and deep faith, Dr. Ott challenges us to uphold the sanctity of life and reflects on the Gospel image at the heart of transplantation – one life given so another may live.

Liver transplantation continues to evolve as strategies expand to address organ shortage and optimize outcomes. Normothermic machine perfusion (NMP) offers a novel way to preserve and assess donor livers prior to implantation. In this episode of Behind the Knife, our transplant team at University of Nebraska Medical Center discusses the latest evidence from randomized trials, practical applications in donation after circulatory death (DCD) grafts, and how NMP is shaping clinical decision-making in high-risk transplants.  Hosts -  Madeline Cloonan, MD PhD, General Surgery Resident, University of Nebraska Medical Center, @maddie_cloonan   - Jacqueline Dauch, MD, Assistant Professor, University of Nebraska Medical Center  -  Shaheed Merani, MD PhD, Associate Professor, University of Nebraska Medical Center  - Alan Langnas, DO, Professor, University of Nebraska Medical Center  Learning Objectives - Describe the principles of normothermic machine perfusion (NMP) and how it differs from static cold storage.  - Summarize the design and key outcomes of the PROTECT trial and the Chapman et al. trial on NMP in liver transplantation.  - Recognize the clinical scenarios where NMP provides the greatest benefit, particularly in high-risk grafts (e.g., DCD donors, high donor risk index).  - Apply a practical viability assessment framework for livers on NMP, including hemodynamics, bile production, lactate trajectory, and histology when indicated.  - Discuss the implications of NMP for allocation, system logistics, and future adoption trends in transplantation.  References   1.     Markmann JF, Abouljoud MS, Ghobrial RM, et al.

Welcome back to our weekend Cabral HouseCall shows!   This is where we answer our community's wellness, weight loss, and anti-aging questions to help people get back on track!   Check out today's questions:    Ashley: Hi Dr. Cabral, love what you've done for the health industry - so much so that I recently graduated as an IHP L2 and will be attending RHS this Fall! I'm writing as I've been experiencing itchy, stinging hives on my face (typically around the chin, mouth and lower cheek area) for 6 months; once the inflammation on the hives settle down I'm left with what appears to be a whitehead. If popped, the skin becomes extremely dry and peels off within 24hrs. I experienced this once in 2018 after a TBI, but worked with a ND (since retired) that resolved my symptoms w/ gut work. I intend to complete the big 5 to asses what's happening, likely followed by a DCD and CBO protocol but would love your thoughts to ensure I'm on the right track and if you have seen these symptoms before. THANK YOU!                                     Tricia: Hi Dr. Cabral - Earlier this year, I had a food sensitivity test done. My bloodwork came in showing above average to tomatoes. The results were 4.7 mcg/ml and anything great than 2 suggests a sensitivity or intolerance. I've been drinking your greens powder every morning and then realized it does have tomatoes but I'm guessing it is a very small amount. Do you think I'm okay to continuing drinking the green powder? I'm working on reducing inflammation in my body. I'm going to retest later this year with your kit. Your test is much more extensive. Thank you!                                                                    Tricia: Hi again, Recent bloodwork showed my Omega 3: EPA at 2.8% by wt is above average. They consider anything above a 2.3 too high. Have you ever seen this before? Not sure why my balance of Omega 3 fatty acids are shifting towards EPA. I was taking your fish oil but have stopped temporarily. All other numbers for Omegas are in range. My total Omega 3 is in range at 7.5. Omega 6-total in range at 39.4. AA/EPA Ratio in range at 4. Homocysteine is 7.7 mcg/dl in range. Omega 6/3 ratio is 5.2. Can I get your opinion please? I know you can't diagnose or treat. I just want your opinion of what it could be and what I should do. Should I continue to take fish oil? I do eat Wild Salmon about 3 times a week. My HS-CRP is 4.1. Thanks for any guidance.                                        Jenny: Hi Dr Cabral - Weighted vests seem to be the latest fitness craze. What is your opinion of them? Thank you!                             Belinda: Please I have ovarian cyst and PID for over four years and I have been taking antibiotics and it's not helping, what should I do           Thank you for tuning into today's Cabral HouseCall and be sure to check back tomorrow where we answer more of our community's questions!    - - - Show Notes and Resources: StephenCabral.com/3501 - - - Get a FREE Copy of Dr. Cabral's Book: The Rain Barrel Effect - - - Join the Community & Get Your Questions Answered: CabralSupportGroup.com - - - Dr. Cabral's Most Popular At-Home Lab Tests: > Complete Minerals & Metals Test (Test for mineral imbalances & heavy metal toxicity) - - - > Complete Candida, Metabolic & Vitamins Test (Test for 75 biomarkers including yeast & bacterial gut overgrowth, as well as vitamin levels) - - - > Complete Stress, Mood & Metabolism Test (Discover your complete thyroid, adrenal, hormone, vitamin D & insulin levels) - - - > Complete Food Sensitivity Test (Find out your hidden food sensitivities) - - - > Complete Omega-3 & Inflammation Test (Discover your levels of inflammation related to your omega-6 to omega-3 levels) - - - Get Your Question Answered On An Upcoming HouseCall: StephenCabral.com/askcabral - - - Would You Take 30 Seconds To Rate & Review The Cabral Concept?

Thank you for joining us for our 2nd Cabral HouseCall of the weekend! I'm looking forward to sharing with you some of our community's questions that have come in over the past few weeks…   Tommy: Hello Stephen. I'm an IHP. A year ago I started having dhiarrea daily. My sleep also suffered, waking up in the night unable to fall back asleep even with magnesium/melatonin/breathwork. I had some leftover healthy belly, so began taking 2 morning and 2 night. Everything cleared up, my bowells were perfect , my mind was clearer, my body was calmer. I thought it was the mastic gum that had killed some h-pylori. About 7 days after stopping healthy belly, it all came back again. I've since done a parasite protocol which i had to stop 11 days before the end as I was feeling fatigued. I ran a stool test just before these symptoms and it showed citrabacter friundi. I'm unsure whether to do a parasite protocol again or run another stool test. Appreciate you                                                                                                                                             Tommy: Hello Stephen, I heard you mention that a certain percentage of folk (possibly with the APOE genotype if memory serves me correctly), experience more inflammation with a higher fat diet. Would it be worth running a generic test to refine my unique needs a bit more as I'm prone to inflammation? Obviously this comes after the basic big 5. And Would it also explain susceptibility to mycotoxins? Thankyou for all that you do             Kay: Hi Dr. Cabral, What would you recommend to 59 or 60 year olds who are a pitta/vata body type and tend to be more catabolic when it comes to your DCD? Would you recommend to modify the 2 fasting days? Both my husband and I are generally ok during Day 1 of the fast, but Day 2 is always so difficult - my husband got bad headaches and because he had to work and focus, he ended up prematurely ending the DCD. I have gotten nausea and chills on Day 2, but the most difficult part for me is just really wanting to eat solid food. It also seems that my muscle tone is weakened afterwards. I know that muscle goes away much quicker when you are over the age of 50. Thanks for all your great podcasts- they are always so informative and I look forward to your response!                                 Kay:  Hi Dr. Cabral- Thanks for your awesome podcasts and the opportunity for us to ask you questions. I'm a 59 year old female and am in menopause. I never had cellulite on my arms and back of my upper thighs and glutes until I began taking HRT. Currently, I am on 1mg oral bioidentical estradiol bid and 100 mg oral progesterone qd at bedtime. I also recently began taking 5 mg DHEA (equilife) bid. I am at a good weight (5'2" 110) and do strength training 3 x per week and walk an average of 10k steps per day. I also have recently incorporated your dry brushing techniques and plan to switch to topical HRT sometime this year with the help of my medical provider. I am wondering what else I can do to eliminate the cellulite?                                                                                                                                                                Shelley: Hello, Dr. Cabral! I have recently gone on a health and wellness journey, going from 228 lbs down to now 167 pounds in just over a year. To aid in the process, of course exercise was a part of it. With the exercise came all the injuries of olde, but mainly my knee. I injured it back in my college years playing tennis and surgery wasn't recommended as they wanted to see if it would heal itself (torn meniscus, mostly in the vascular area). Well, fast forward more years than I care to count, and that residual tear on the avascular portion can be problematic. I have been looking into peptides, specifically BPC-157 and TB-500 to potentially help this knee without surgical intervention. What are your thoughts on peptide use (these two in particular) and do you think they might help my knee?           Thank you for tuning into this weekend's Cabral HouseCalls and be sure to check back tomorrow for our Mindset & Motivation Monday show to get your week started off right! - - - Show Notes and Resources: StephenCabral.com/3467 - - - Get a FREE Copy of Dr. Cabral's Book: The Rain Barrel Effect - - - Join the Community & Get Your Questions Answered: CabralSupportGroup.com - - - Dr. Cabral's Most Popular At-Home Lab Tests: > Complete Minerals & Metals Test (Test for mineral imbalances & heavy metal toxicity) - - - > Complete Candida, Metabolic & Vitamins Test (Test for 75 biomarkers including yeast & bacterial gut overgrowth, as well as vitamin levels) - - - > Complete Stress, Mood & Metabolism Test (Discover your complete thyroid, adrenal, hormone, vitamin D & insulin levels) - - - > Complete Food Sensitivity Test (Find out your hidden food sensitivities) - - - > Complete Omega-3 & Inflammation Test (Discover your levels of inflammation related to your omega-6 to omega-3 levels) - - - Get Your Question Answered On An Upcoming HouseCall: StephenCabral.com/askcabral - - - Would You Take 30 Seconds To Rate & Review The Cabral Concept?

We catch up with Keynote speaker: Professor Jill ZwickerDCD and ADHD keynote: How do developmental coordination disorder and ADHD intersect, and what are the implications for diagnosis and treatment?Join us for another brilliant conversation with a brilliant researcher - live from the EACD / IAACD Conference 2025, in Heidelberg Germany!

I'm joined today by two special guests to discuss an unusual and ethically complex type of organ donation – imminent death donation, or IDD. As you'll hear Thao Galvan explain in the episode, organ donation currently has three standard types: living donation, donation after brain death (a type of deceased donation in which the patient is declared brain dead, and thus legally dead), and donation after circulatory death, or DCD. In DCD, a patient who is not brain dead is removed from life support, but the heart keeps beating. If it takes the patient more than roughly 90 minutes to die, the organs may not be usable. IDD, or imminent death donation, attempts to prevent that, by retrieving non-vital organs (usually a kidney) for donation prior to the removal of life support. Thao Galvan is a transplant surgeon and professor of surgery at Baylor College of Medicine. Kathy Osterrieder is a retired financial analyst, who came to this issue after attempting, unsuccessfully, to donate the organs of her late husband, Robert Osterrieder, after making the difficult decision to remove him from life support. It is another first for the Taboo Trades podcast – the first time in over five years of recording that I've been unable to hold back the tears, as Kathy talks about what the experience was like for her family. LinksHost: Kimberly D.

DCD's EiC Sebastian Moss talks to SDxCentral executive editor Dan Meyer about what it means for the two publications to work together, and what we can learn about the current tech cycle from previous booms and busts.

What is the role of ferroptosis, programmed cell death characterized by intracellular iron accumulation and lipid peroxidation, in the context of ischemic injury related to heart transplantation? In this episode, Associate Editor Dr. Amanda LeBlanc (University of Louisville) interviews authors Dr. Kenneth Liao and Dr. Nandan Mondal (both at Baylor College of Medicine), along with expert Dr. Zachary Kiernan (Virginia Commonwealth University) about the latest study by Li et al. The authors found that prolonged cold storage increases the susceptibility of hearts donated after brain death (DBD) to ferroptotic cell death. In contrast, however, the authors found that warm ischemic injury increased the risk for ferroptotic cell death in hearts donated after circulatory death (DCD). Li et al. found that targeting ferroptosis could be beneficial for optimizing cold preservation for DBD hearts, while interventions for DCD hearts should focus on the early phase of warm ischemia. Heart transplantation is the gold standard therapy for patients with medically refractory advanced heart failure. However, demand greatly exceeds supply of donor hearts. Listen as we discuss the current state of the heart transplantation field and the many challenges it faces.   Shiyi Li, Katherine V. Nordick, Abdussalam E. Elsenousi, Rishav Bhattacharya, Randall P.

Mastering NRP for Organ Donation Success NRP is rewriting organ donation rules, and Matt Warhoover, CCP, takes you inside this bold frontier over a two-hour session. Using ECMO or bypass, NRP restarts circulation after circulatory death to recover organs in situ. Warhoover will cover cannulation, perfusion, and the ethics of this gray zone. I'll weigh in on its promise—like turning DCD into multi-organ wins—and its hurdles. You'll compare it to standard methods and see its impact on the donor pool. Perfusionists will find new turf here; transplant pros will grasp its potential. Dive in to shape the future of donation.

RE-RELEASED EPISODE This week on the Military Life Podcast, I speak with Army spouse Mel about a service dog called Maxx and how he saved her husband Damien. Mel and I also speak about; -What it's like when your Husband deploys every two years -Her Husband's decision to be proactive in seeking mental health support -Why a service dog was the right fit for her Husband and their family -Defence Community Dog program and the support the Defence Bank Foundation give the program -The impact Maxx has had on her Husband's everyday life and their family life -The type of support Maxx provides and why Mel being the third wheel is a good thing   Maxx was matched with Damien through the Defence Community Dog Program, a program that is funded by the Defence Bank Foundation thanks to Defence Bank. The DCD program provides highly trained service dogs to serving and ex-serving ADF members who need physical and emotional support for mood, depressive and anxiety disorders including Post-Traumatic Stress Disorder (PTSD). Every dog in the program is rescued from a pound/shelter/training facility and trained at the Bathurst Correctional Centre with the assistance of professional dog trainers and inmates. The admin costs to run the Defence Bank Foundation are met by Defence Bank to make sure that all donated funds are provided to the Defence Community Dogs program. Visit https://www.defencebankfoundation.com.au/ to make a donation or to find out more info.

Welcome back to our weekend Cabral HouseCall shows! This is where we answer our community's wellness, weight loss, and anti-aging questions to help people get back on track! Check out today's questions:    Ciro: Hi Dr. Cabral.Thank you for all the knowledge that you share.I have a question about weight training. I'm a 45 years old male; weight 194 lbs. and 5ft 11. I have a fairly robust looking body/torso with good muscle percentage in general, but my arms look very lean in comparison to the rest of my body. My biceps get toned fairly easily but my triceps just won't get toned. I don't take any supplements with regards to muscle gain, but I do weight training (using YBELL training or CrossFit inspired exercises) 2 times a week and soccer once a week. I go to a gym now but have the YBELL's at home as well. What would you recommend I look into? Which specific exercises do you recommend me doing so the arms will be more toned and specifically the triceps and shoulders?   Julia: Hi Dr. Cabral! I was wondering what your thoughts are on young livings Ningxia Red. They claim that “antioxidant drink is clinically shown to increase physical energy levels, improve sleep patterns, and reduce daily stress. It's packed with powerful antioxidants to help against oxidative stress, support normal cellular function, and promote healthy energy levels.” Some people I know swear by it and drink it daily and it anted to know if it's a good product. I searched the archive and couldn't find anything on it. Maybe you can do a product review? Thanks!   Natalia: Hi Stephen - I've been listening to your podcasts for a couple months now and they have helped me so much and I'm implementing things as I go. I feel fantastic so far on a 14 hour fast etc, but I would love to know how I can help my partner who has Chrons - he had the bag for a year, he had the surgery - the bag was removed - but they anticipate he will have more surgery - I would love to avoid that - his diet recommendations are so different to what I know as ‘right' for most people his diet recommended white bread, white rice, no vege skins etc. would you recommend he do a full lab test? He works hard all day - but he gets tired - I would just love to help go feel as energetic as I feel now - pls direct me to how I can help him - thanks   Samantha: Hello, I listen to the podcast all the time and it has helped me so much. Thank you for sharing your wealth of knowledge with us. My question is I have been told to stop taking DIM if I'm taking HRT. I only use the oestrogen gel as I have a Mirena coil fitted for progesterone. Please can you tell me if this is correct? Also please can you comment on hearing aids with blue tooth are they safe? Much appreciated. Samantha   Anonymous: Thank you for all you do! I've done a lot of work on my health (multiple DCD, CBO, HMD, take daily supplements, etc.). One thing I'm working on is getting into the parasympathetic more and lowering my slightly elevated heart rate. I've listened to podcasts on this subject and your interview with Patrick McKeown on how important breathing is. It seems every time I focus on my breath I feel more stressed. I've tried different breathing techniques, yoga and I make sure I'm not over oxygenating. It just seems to raise my heart rate and I haven't seen the relaxing benefits. Even when I try not to manipulate my breath and just move my focus to it, I feel the stress response. Any suggestions? Thanks   Thank you for tuning into today's Cabral HouseCall and be sure to check back tomorrow where we answer more of our community's questions!    - - - Show Notes and Resources: StephenCabral.com/2682 - - - Get a FREE Copy of Dr. Cabral's Book: The Rain Barrel Effect - - - Join the Community & Get Your Questions Answered: CabralSupportGroup.com - - - Dr. Cabral's Most Popular At-Home Lab Tests: > Complete Minerals & Metals Test (Test for mineral imbalances & heavy metal toxicity) - - - > Complete Candida, Metabolic & Vitamins Test (Test for 75 biomarkers including yeast & bacterial gut overgrowth, as well as vitamin levels) - - - > Complete Stress, Mood & Metabolism Test (Discover your complete thyroid, adrenal, hormone, vitamin D & insulin levels) - - - > Complete Food Sensitivity Test (Find out your hidden food sensitivities) - - - > Complete Omega-3 & Inflammation Test (Discover your levels of inflammation related to your omega-6 to omega-3 levels) - - - Get Your Question Answered On An Upcoming HouseCall: StephenCabral.com/askcabral - - - Would You Take 30 Seconds To Rate & Review The Cabral Concept?
