#Com Dra. Valderês A. Robinson Achutti (*13/06/1931+15/16/2021)

Como está fazendo muito calor, preferi convidar os amigos para visitarmos as montanhas no norte da Italia (Dolomiti). Também, nosso Natal costumava ter algodão na decoração do pinheiro, imitando flocos de neve...

PAPAI NOEL?

Aloyzio Achutti (2016)

    Dá para acreditar no Papai Noel? A pergunta parece descabida, mas muitos de nós aceitamos essa ilusão durante algum tempo em nossa infância, assim como até hoje toleramos sem discutir muita coisa incerta, ilusória ou mentirosa. Convém crer, é melhor não duvidar, nem perguntar, e pode até não haver resposta…

    É preciso haver um mínimo de compatibilidade entre conhecimentos e “verdades”  utilizados em nosso cotidiano e, ao mesmo tempo, uma boa margem de tolerância, ou explicação razoável, para juntar ideias aparentemente conflitantes. Para viver bem não precisamos estar tentando testar a veracidade a cada momento, nem é preciso que todos tenhamos crenças iguais. Basta haver equilíbrio e estabilidade  no conjunto de crenças de cada um, e haja respeito à diversidade.

    Há quem diga que aquilo que chamamos de realidade não existe de fato (assim como Papai Noel), cada um lança mão da imaginação para construir um mundo como gostaria que fosse, ou como convém, e fique compatível com o restante de nossa memória pessoal. Dúvidas, discordâncias e contestações, nos causam algum desconforto, mas terminamos por nos acomodar.

    A ciência foi criada para colocar um mínimo de ordem na casa, mas mesmo existindo um arquipélago de postulados científicos bastante sólidos nos quais nos agarramos, sobra sempre espaço a ser preenchido pela imaginação.

    Gosto de repetir a frase de Albert Einstein: “imaginação é mais importante que o conhecimento”.

    Afinal de contas não sabemos de onde, nem como surgimos, nem para onde vamos como espécie, nem o sentido e o destino desse mundo. Imaginamos um universo imenso, a se perder no limite da capacidade de nossos sentidos, e das máquinas inventadas para enxergar  o inatingível. Mesmo assim, pelas distâncias que nos separam, estamos recém recebendo e misturando informações  de mundos provavelmente já desaparecidos. 

    Não sabemos o que preenche os espaços entre os astros e seres palpáveis de cuja existência não ousamos duvidar, nem do microcosmo de partículas componentes cuja realidade está a exigir cada vez mais definições, teorias e elucubrações só concebíveis no domínio da imaginação…

    Minha intenção inicial era explorar o clima de descrédito e insegurança no qual vivemos, onde não sobra mais ninguém para se acreditar - assim como Papai Noel que já se foi. Ninguém sabe, ninguém viu, não há provas materiais, só indícios que podem corresponder a um plano conspiratório...

    Ainda, voltando ao espírito natalino materializável na troca de presentes, deveríamos falar sobre o circuito da recompensa, radicado na satisfação gerada pelo mimo, pelo carinho, por qualquer ganho, propina, poder, perpetuando o caminho do prazer e do sucesso, no funcionamento do circuito cerebral naturalmente desenvolvido para garantir sobrevivência e evolução das espécies, mas isso terá que ficar para outra ocasião. 

    Enquanto isso - Feliz Natal!...

#É Natal!

The evolution of medicine as a profession. A 75-year perspective

F Hafferty 1, J C Salloway 

PMID: 8426585 
Abstract
Recomendação da Prof. Maria Inês Reinert Azambuja
The profession of medicine has changed dramatically in 75 years. Despite the commitment of individual practitioners to the highest ideals of professionalism, the profession itself has lost privilege, power, and public reputation. It has been toppled from the high moral ground of professionalism. This has happened not so much because individual clinicians have abandoned that ground, but largely because others have occupied it--primarily complex organizations that have developed public mandates to regulate and oversee health care. The issue is not one of unfeeling physicians--it is one of a health care system that has evolved so as to limit medicine's autonomy. This changing system places new constraints and pressures on the physician-patient relationship. The question we are left with is whether medicine can regain its professionalism. How do we reform a system that, by its complexity, has become amoral? The only way is for physicians to re-assume a stout position of advocacy--advocacy for individual patients in a complex and frightening system of care, advocacy for patients as a class of people in a political system that seeks to restrict care, advocacy for patients in a world of environmental and epidemic threats. Such advocacy requires an equally strong moral commitment to the principles of service. Acting in the patient's best interest is not enough. It requires that the profession avoid the appearance of blatant self-interest at every turn. It requires a revised commitment to political activism in the interest of service to patients as a community. The costs are extremely high--but the alternative, physicians-as-technicians and medicine as a slave to corporate and government interests, is hardly acceptable.

#Time

A quick programming note: Health Matters will be off next week, and return on Jan. 2. From all  of us on the TIME health team, we wish you a happy and health new year.  Health journalists should be some of the healthiest people around. All day long, we call up experts and ask them what people can do to live long and full lives. But knowing what's good for you doesn't always translate into optimal behaviors. We deprioritize exercise, spend hours scrolling through social media, and eat too many Christmas cookies. (Maybe just like you.) This year, everyone on our team made time for at least one new activity we felt sure would enrich our lives. From eating more ice cream to rage biking, some stuff worked so well that we're planning to take it with us into the new year.
