This document discusses teratogens and endocrine disruptors. It defines teratogens as agents that can permanently alter development, giving examples like thalidomide and rubella virus. Endocrine disruptors are chemicals that interfere with hormone signaling and include many pesticides, plastics, and pharmaceuticals. These chemicals are linked to developmental abnormalities, reproductive issues, cancer risks, and other health impacts due to their effects on hormone receptors and hormone levels during development. While natural hormones have always been present, the abundance of synthetic endocrine disruptors is posing new challenges to human health and physiology.

Nuestro futuro robado. La amenaza de los disruptores endócrinos
Por José Santamarta
Nuestro futuro robado, escrito por Theo Colborn, Dianne Dumanoski y Pete Myers, reunió por primera vez las alarmantes evidencias obtenidas en estudios de campo, experimentos de laboratorio y estadísticas humanas, para plantear en términos científicos, pero accesibles para todos, el caso de este nuevo peligro.
En 1962 el libro de Rachel Carson Primavera silenciosa dio el primer aviso de que ciertos productos químicos artificiales se habían difundido por todo el planeta, contaminando prácticamente a todos los seres vivos hasta en las tierras vírgenes más remotas. Aquel libro, que marcó un hito, presentó pruebas del impacto que dichas sustancias sintéticas tenían sobre las aves y demás fauna silvestre. Pero hasta ahora no se habían advertido las plenas
consecuencias de esta insidiosa invasión, que está trastornando el desarrollo sexual y la reproducción, no sólo de numerosas poblaciones animales, sino también de los seres humanos.

What Is Fetal Alcohol Syndrome?
1) When a pregnant person drinks alcohol, some of that alcohol easily passes across the placenta to the fetus.
2) People with this condition may have problems with their vision, hearing, memory, attention span, and abilities to learn and communicate.
3) You can prevent fetal alcohol syndrome by avoiding alcohol during pregnancy.
Prenatal development: germinal, embryonic &fetal period; Factors that can have a serious negative impact on the development of the unborn: maternal health, radiation, maternal nutrition, medication and drugs, age of the parents, diseases in the pregnant woman and the emotional state of the mother.

TOPIC: “Chemical Exposures & Life-Long Reproductive Health Impacts”
We will review what we understand about reproductive biology and environmental contamination exposure. We’ll discuss the role of environmental chemicals in breast development and puberty, increased susceptibility to breast cancer and exposures during early life development of both male and female offspring and life-long impacts from chemical exposure. We’ll also discuss some of the potential health implications of energy development based on what we currently understand about exposures during early reproductive and developmental biology.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

development, numerous environmental factors
can disrupt development
Abnormalities caused by exogenous
agents are called ‘disruptions’
Agents responsible for these disruptions are
called ‘teratogens’.

normal endocrine system actions leading to
deleterious effects on an organism or its progeny.
Disruptors may act directly or indirectly.
Direct acting disruptors are usually hormone
agonists or antagonists that interfere with
hormone actions on target cells.
Indirect acting disruptors alter hormone dynamics
in circulation, change hormone metabolism, or
interfere with hormone regulation.

17. Hormone Receptors are cellular proteins
that bind with high affinity to hormones &
are altered in shape & function by
binding; they exist in limited numbers.
Binding to hormone is noncovalent &
reversible.
Hormone binding will alter binding to
other cellular proteins & may activate
any receptor protein enzyme actions.
18. Membrane Receptors
Imbedded in target cell membrane; integral proteins/
glycoproteins; penetrate through membrane
For protein & charged hormones (peptides or
neurotransmitters)
3 major groups: Serpentine = 7 transmembrane
domains, Growth factor/cytokine = 1 transmembrane
domain, Ion channels
Nuclear Receptors
Nuclear proteins that usually act in pairs & bind to
specific Hormone Recognition Elements (HREs) =
sequences on the DNA in the promoter regions of
target genes
For small, hydrophobic molecules (steroids, thyroid
hormones)

22. Hormones & receptors co-evolve. It is common to have
several hormone receptors demonstrate varying affinity for
the same hormone. It is also common for one hormone to
have some affinity for several different receptor types.

31. Endocrine disruptors or hormonally active
agents have been with us for millennia as
elements of plants and cooking. The new
abundance of synthetic compounds has
unleashed a wave of new challenges to our
physiology, including the endocrine system.
The impacts are as pleiotropic as endocrine
actions are. Not surprisingly they involve
altered reproductive success, growth, and
cancer risks because of endocrine controls or
inputs in these processes. Due care will help
minimize impacts, but some increased risks
are here permanently.
