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.

Tom Selleck Health: A Comprehensive Look at the Iconic Actor’s Wellness Journeygreendigital
Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
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

Epilepsy-Epidemiology,Signs and symptoms,Triggers,Seizures types,Causes ,Diagnosis,anti epileptic drugs
1. • Epilepsy is a group of neurological
disorders characterized by epileptic seizures.
Epilepsy
• Epileptic seizures are episodes that can vary
from brief and nearly undetectable periods to
long periods of vigorous shaking
• The cause of most cases of epilepsy is unknown
• Some cases occur as the result of brain
injury, stroke, brain tumors, infections of the
brain, and birth defects through a process
known as epileptogenesis.
2. Epidemiology
• Epilepsy is one of the most common serious
neurological disorders affecting about 39 million
people as of 2015. It affects 1% of the population by
age 20 and 3% of the population by age 75. It is more
common in males than females with the overall
difference being small. Most of those with the disorder
(80%) are in the developing world.
. Epilepsy begins each year in 40–70 per 100,000 in
developed countries and 80–140 per 100,000 in
developing countries. Poverty is a risk and includes both
being from a poor country and being poor relative to
others within one's country . In the developing world its
onset is more common in older children and young adults
due to the higher rates of trauma and infectious diseases.
3. Signs and symptoms
Epilepsy is characterized by a long-term risk of
recurrent seizures. These seizures may present in
several ways depending on the part of the brain
involved and the person's age
• Seizures
• Post- ictal
• Psychosocial
4. Triggers
• Medication
Not taking one’s anti-epileptic medication
Other medications that are taken in addition to anti-epileptic
medication
• Internal Factors
• Stress, excitement and emotional upset
• This type of over-stimulation may lower the person’s resistance to
seizures by affecting sleeping or eating habits.
• Boredom
• Research shows that individuals who are happily occupied are less
likely to have a seizure.
• Lack of sleep can change the brain’s patterns of electrical activity and
can trigger seizures.
• Fevers may make some children more likely to have a seizure.
• Menstrual cycle
• Many females find their seizures increase around this time of their
period. This is referred to as catamenial epilepsy and is because of
changes in hormone levels, increased fluid retention and changes
in anti-epileptic drug levels in the blood.
5. External Factors
• Alcohol can affect the rate at which the liver breaks down anti-
epileptic medication.
• This may decrease the blood levels of anti-epileptic medications,
affecting an individual’s seizure control.
• Poor diet
• Many seizures take place when blood sugar is low.
• Stimulants such as tea, coffee, chocolate, sugar, sweets, soft
drinks, excess salt, spices and animal proteins may trigger seizures
by suddenly changing the body’s metabolism.
• Some parents have reported that allergic reactions to certain foods
(e.g. white flour) also seem to trigger seizures in their children.
• Certain nutrient shortages, such as a lack of calcium, have also
been found to trigger seizures.
• Very warm weather, hot baths or showers, especially when there is a
sudden change in temperature.
• Television, videos and flashing lights
• The “strobe effect” from fast scene changes on a bright screen,
rapidly changing colours or fast-moving shadows or patterns can all
be trigger seizures.
6. Seizures
The most common type (60%) of seizures are convulsive . Of these, one-third
begin as generalized seizures from the start, affecting both hemispheres of the
brain. Two-thirds begin as focal seizures (which affect one hemisphere of the
brain) which may then progress to generalized seizures . The remaining 40% of
seizures are non-convulsive.
There are six main types of generalized seizures:-
• tonic- clonic
• tonic
• clonic
• myoclonic
• absence
• atonic seizures .
They all involve loss of consciousness and typically happen without warning.
7. • Tonic-clonic seizures occur with a contraction of the limbs
followed by their extension along with arching of the back which lasts 10–
30 seconds (the tonic phase). A cry may be heard due to contraction of
the chest muscles, followed by a shaking of the limbs in unison (clonic
phase).
• Tonic seizures produce constant contractions of the muscles. A
person often turns blue as breathing is stopped.
• Clonic seizures there is shaking of the limbs in unison. After
the shaking has stopped it may take 10–30 minutes for the person to
return to normal; this period is called the "postictal state" or "postictal
phase."
• Myoclonic seizures involve spasms of muscles in either a few
areas or all over.
• Absence seizures can be subtle with only a slight turn of
the head or eye blinking.
• Atonic seizures involve the loss of muscle activity for greater
than one second. This typically occurs on both sides of the body
8. Post-ictal
After the active portion of a seizure
(the ictal state) there is typically a period of
recovery during which there is confusion, referred
to as the postictal period before a normal level of
consciousness returns. It usually lasts 3 to 15
minutes but may last for hours.
Other common symptoms include feeling
tired, headache , difficulty speaking, and abnormal
behavior. Psychosis after a seizure is relatively
common, occurring in 6–10% of people.
9. Psychosocial
Epilepsy can have adverse effects on social and psychological
well-being. These effects may include social isolation,
stigmatization, or disability. They may result in lower
educational achievement and worse employment outcomes
.Learning disabilities are common in those with the
condition, and especially among children with epilepsy .
Certain disorders can
occur depression, anxiety, obsessive–compulsive
disorder (OCD), and migraine. Attention deficit
hyperactivity disorder affects three to five times more
children with epilepsy than children without the
condition. ADHD and epilepsy have significant consequences
on a child's behavioral, learning, and social development.
Epilepsy is also more common in children with autism .
10. Causes
Epilepsy can have both genetic and acquired causes, with interaction of
these factors in many cases. Established acquired causes include serious
brain trauma, stroke, tumours and problems in the brain as a result of a
previous infection . In about 60% of cases the cause is unknown. Epilepsies
caused by genetic , congenital , or developmental conditions are more
common among younger people, while brain tumors and strokes are more
likely in older people.
Seizures may also occur as a consequence of other health problems; if they
occur right around a specific cause, such as a stroke, head injury, toxic
ingestion or metabolic problem, they are known as acute
symptomatic seizures and are in the broader classification of seizure-
related disorders rather than epilepsy itself.
11. Genetics
• Some epilepsies are due to a single gene defect (1–2%); most are
due to the interaction of multiple genes and
environmental factors.
• Most genes involved affect ion channels, either directly
or indirectly. These include genes for ion
channels themselves, enzymes , GABA, and G
protein-coupled receptors .
• In identical twins , if one is affected there is a 50–60% chance that
the other will also be affected . In non-identical twins the risk is
15%. These risks are greater in those with generalized rather than
focal seizures. If both twins are affected, most of the time they have
the same epileptic syndrome (70–90%).
12. Acquired
Epilepsy may occur as a result of a number of other conditions including
tumors, strokes, head trauma, previous infections of the central nervous system,
genetic abnormalities, and as a result of brain damage around the time of birth.
Of those with brain tumors, almost 30% have epilepsy, making them the cause of
about 4% of cases. The risk is greatest for tumors in the temporal part and those
that grow slowly. Other mass lesions such as cerebral cavernous
malformations and arteriovenous malformations have risks as high as 40–
60%.Of those who have had a stroke, 2–4% develop epilepsy. In the United
Kingdom strokes account for 15% of cases and it is believed to be the cause in 30%
of the elderly. Between 6 and 20% of epilepsy is believed to be due to head
trauma. Mild brain injury increases the risk about two-fold while severe brain
injuryincreases the risk seven-fold. In those who have experienced a high-
powered gunshot wound to the head, the risk is about 50%.
Some evidence links epilepsy and coeliac disease and non-celiac gluten sensitivity
, while other evidence does not. There appears to be a specific syndrome which
includes coeliac disease, epilepsy and calcifications in the brain. A 2012 review
estimates that between 1% and 6% of people with epilepsy have CD while 1% of
the general population has the condition.
13. Mechanism
Normally brain electrical activity is non-
synchronous. Its activity is regulated by various factors
both within the neuron and the cellular environment.
Factors within the neuron include the type, number
and distribution of ion channels, changes
to receptors and changes of gene expression . Factors
around the neuron include ion concentrations, synaptic
plasticity and regulation of transmitter breakdown
by glial cells.
14. Epilepsy
The exact mechanism of epilepsy is unknown, but a little is known
about its cellular and network mechanisms. However, it is unknown
under which circumstances the brain shifts into the activity of a
seizure with its excessive synchronization.
In epilepsy, the resistance of excitatory neurons to fire
during this period is decreased. This may occur due to
changes in ion channels or inhibitory neurons not functioning
properly. This then results in a specific area from which seizures
may develop, known as a "seizure focus".[ Another mechanism of
epilepsy may be the up-regulation of excitatory circuits or down-
regulation of inhibitory circuits following an injury to the
brain. These secondary epilepsies occur through processes
known as epileptogenesis .Failure of the blood–brain barrier may
also be a causal mechanism as it would allow substances in the
blood to enter the brain.
15. Seizures
Seizures are often brought on by factors such as stress, alcohol abuse,
flickering light, or a lack of sleep, among others. The term seizure
threshold is used to indicate the amount of stimulus necessary to bring
about a seizure. Seizure threshold is lowered in epilepsy.
In epileptic seizures a group of neurons begin firing in an
abnormal, excessive, and synchronized manner. This results
in a wave of depolarization known as a paroxysmal depolarizing shift.
Normally, after an excitatory neuron fires it becomes more resistant to
firing for a period of time. This is due in part to the effect of inhibitory
neurons, electrical changes within the excitatory neuron, and the
negative effects of adenosine.
Focal seizures begin in one hemisphere of the brain while
generalized seizures begin in both hemispheres. Some types
of seizures may change brain structure, while others appear to have
little effect. Gliosis, neuronal loss, and atrophy of specific areas of the
brain are linked to epilepsy but it is unclear if epilepsy causes these
changes or if these changes result in epilepsy
17. An EEG can aid in locating the focus of the epileptic seizure.
The diagnosis of epilepsy is typically made based on observation of the seizure
onset and the underlying cause. An electroencephalogram (EEG) to look for
abnormal patterns of brain waves and neuroimaging (CT scan or MRI) to look at
the structure of the brain are also usually part of the workup. While figuring
out a specific epileptic syndrome is often attempted, it is not always
possible. Video and EEG monitoring may be useful in difficult cases
Diagnosis
18. Diet
A ketogenic diet (high-fat, low-carbohydrate, adequate-
protein) appears to decrease the number of seizures and
eliminate seizures in some, however further research is
necessary. It is a reasonable option in those who have
epilepsy that is not improved with medications and for
whom surgery is not an option. About 10% stay on the diet
for a few years due to issues of effectiveness and
tolerability. Side effects include stomach and intestinal
problems in 30%, and there are long-term concerns about
heart disease. Less radical diets are easier to tolerate and
may be effective. It is unclear why this diet works.
Exercise has been proposed as possibly useful for
preventing seizures with some data to support this claim.
19. Surgery
Epilepsy surgery may be an option for people with focal seizures that remain a
problem despite other treatments. These other treatments include at least a trial
of two or three medications. The goal of surgery is total control of
seizures[107] and this may be achieved in 60–70% of cases. Common procedures
include cutting out the hippocampus via an anterior temporal lobe resection,
removal of tumors, and removing parts of the neocortex. Some procedures such
as a corpus callosotomy are attempted in an effort to decrease the number of
seizures rather than cure the condition. Following surgery, medications may be
slowly withdrawn in many cases.
Neurostimulation may be another option in those who are not candidates for
surgery.[63] Three types have been shown to be effective in those who do not
respond to medications: vagus nerve stimulation, anterior thalamic stimulation,
and closed-loop responsive stimulation.
20. Mortality
People with epilepsy are at an increased risk of death.[124] This
increase is between 1.6 and 4.1 fold greater than that of the general
population[125] and is often related to: the underlying cause of the
seizures, status epilepticus, suicide, trauma, and sudden unexpected
death in epilepsy (SUDEP). Death from status epilepticus is primarily
due to an underlying problem rather than missing doses of
medications. The risk of suicide is between two and six times higher
in those with epilepsy. The cause of this is unclear. SUDEP appears to
be partly related to the frequency of generalized tonic-clonic seizures
and accounts for about 15% of epilepsy related deaths. It is unclear
how to decrease its risk. The greatest increase in mortality from
epilepsy is among the elderly . Those with epilepsy due to an
unknown cause have little increased risk.[ In the United Kingdom, it is
estimated that 40–60% of deaths are possibly preventable. In the
developing world, many deaths are due to untreated epilepsy leading
to falls or status epilepticus.
21. Tests
An electroencephalogram (EEG) can assist in showing brain
activity suggestive of an increased risk of seizures. It is only
recommended for those who are likely to have had an
epileptic seizure on the basis of symptoms. In the diagnosis
of epilepsy, electroencephalography may help distinguish
the type of seizure or syndrome present. In children it is
typically only needed after a second seizure. It cannot be
used to rule out the diagnosis and may be falsely positive in
those without the disease. In certain situations it may be
useful to perform the EEG while the affected individual is
sleeping or sleep deprived.
Diagnostic imaging by CT scan and MRI is recommended
after a first non-febrile seizure to detect structural
problems in and around the brain . MRI is generally a better
imaging test except when bleeding is suspected, for which
CT is more sensitive and more easily available.
