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.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

10. “Everything I do is slow. I walk, talk, and think slowly… I still
have no short-term memory…
Much of the time I can't even remember the names of relatives
and close friends… I am always confused…
Because I look normal and often sound normal, people
assume I am normal. But I'm not…
I get depressed a lot knowing that I will never have my
competence back.”

11. • Whole-brain radiotherapy (WBRT) is the most widely
used treatment option for patients with multiple brain
metastases
• Benefits
• rapid palliation of neurologic symptoms
• improved local control as an adjuvant to resection or
radiosurgery.
• prolongs time to neurocognitive function (NCF)
decline.( deterioration in NCF preceded self-reported quality of
life decline by up to 153 days)
WBRT
12. • Before 1970, the human brain was thought
to be radioresistant;
• the acute central nervous system (CNS)
syndrome occurs after single doses of ≥30
Gy, and white matter necrosis can occur at
fractionated doses of ≥60 Gy
CNS Toxicity
13. • Radiation necrosis of the brain typically
occurs 3 months to several years after
radiotherapy (median 1–2 years)
• Emami et al
• 5% risk of radionecrosis at 5 years with
a dose of 60 Gy to one-third of the brain
with standard fractionation
• Quantec : For standard fractionation, the
incidence of radionecrosis appears to be
• <3% for a dose of <60 Gy.
• 5% with a dose of 72 Gy
• 10% with a dose of 90 Gy. However
But that’s not what we are talking
about!!
14. • Early neurocognitive decline, within the
first 1-4 months, which primarily reflects
memory.
• Long-term serious and permanent adverse
effects, including cognitive deterioration in
other domains and cerebellar dysfunction
• As many as11% of long-term brain
metastases survivors (>12 months) treated
with WBRT develop severe dementia,
especially with the use of larger dose-per-
fraction schedules
Neuro-cognitive toxicity in
WBRT
15. • According to the principle of double effect,
• “sometimes it is permissible to cause a harm as a
side effect (or “double effect”) of bringing about a
good result even though it would not be permissible
to cause such a harm as a means to bringing about
the same good end.”
Doctrine of Double Effect

PATHOGENESIS
17. • Approximately 100 000 patients per year
in the United States with primary and
metastatic brain tumor survive long
enough (>6 months) to develop
radiation-induced brain injury
Is this a big deal in these stage IV
patients?
18.
19. • At 4 months
• HA-WBRT versus WBRT
• 7% vs 30% memory score decline
• measured by the Hopkins Verbal
Learning Test (HVLT).
• By 6 months post-treatment, decline was 2
percent, on average

23. • MRI:
• 3D-SPGR axial MRI scan of the head with standard axial and coronal
FLAIR, axial T2-weighted and gadolinium contrast-enhanced T1-
weighted sequence acquisitions .
• 1.25mm slice thickness is preferred to contour the hippocampus
accurately. Slice thickness of 1.5mm or less is permitted.
• Obtain in supine position; immobilization devices used for CT simulation
and daily radiation treatments not necessary.
• CT Simulation:
• Non-contrast treatment-planning CT scan of the entire head region.
• 1.25-1.5mm slice thickness is preferred for accurate hippocampal
sparing planning. Slice thickness of 2.5mm or less is permitted.
• Immobilize patient in supine position using an immobilization device such
as an Aquaplast mask over the head. Treat patients in the
immobilization device.
• MRI-CT Fusion:
• Fuse the 3D-SPGR MRI and the treatment-planning CT.
