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).

2. BATH SALTS
Sing-Yi Feng, MD FAAP
Assistant Professor of Pediatrics/Medical Toxicologist
UT Southwestern Medical Center at Dallas
“Bath salts” were first reported as drug of abuse to
the North Texas Poison Center in 2010. Since then, Poison
Centers across the United States have reported increasing
numbers of calls involving “bath salts”. These “bath salts”
usually contain mephedrone and
methylenedioxypyrovalerone (MDPV) and are insufflated or
“snorted” much like cocaine.
Mephedrone is a synthetic stimulant of the
amphetamine and cathionine class.
Methylenedioxypyrovalerone is also a synthetic stimulant
with effects similar to amphetamines. Both drugs have
been reported to cause agitation, euphoria, hypertension
and tachycardia. These effects resemble
methamphetamine and cocaine toxicity. Patients can also
develop hyperthermia and ultimately rhabdomyolysis, end
organ failure and possibly death from the use of “bath
salts.” So far, one
death in Florida in
2011 has been
attributed to the
use of bath salts.
Bath salts
are easily
purchased on the
Internet and at
“head shops.” It
is considered a
designer drug
because although
mephedrone and
MDPV have never
been used for
bath salts, they
are labeled as
such with the
phrase “Not for
Human
Consumption” in
order to bypass
the Federal
Analog Act. The
Federal Analog
Act of the United
States Controlled
Substance Act states that any chemical "substantially
similar" to a controlled substance listed in Schedule I or II
is to be treated as if it were also listed in those schedules,
but only if intended for human consumption. Many states
such as Florida have now made the substances contained
in bath salts illegal to own and sell. Also, as of September
7, 2011, The United States Drug Enforcement
Administration (DEA) used its emergency scheduling
authority to temporarily control mephedrone. This was
deemed necessary to protect the public from the
supposed hazard posed by the drug. Except as authorized
by law, this action will make possessing and selling
mephedrone or the products that contain it illegal in the
U.S. for at least one year while the DEA and the United
States Department of Health and Human Services conduct
further study.

University of Minnesota Amplatz Children's Hospital
This is a case of 14 y/o male who had altered mental status and was found to be hypothermic with a
temperature of 91 F on the street. His EKG showed Osborne or J wave ( marked in the EKG ) which is the
upward deflection at the junction of QRS and ST representing distortion in the earliest phase of repolarization.
J waves are usually observed in people suffering from hypothermia with a temperature of less than 32 C
though they may also occur in people with high blood levels of calcium, brain injury, vasoplastic angina.

Heat illness is defined as “the

Heat stroke is a life-

to the environment.” Heat stroke

as severe hyperthermia (>40*C),
occurs when the excess body
temperature results in cellular injury,
with severe CNS dysfunction.

Ascaris
lumbricoides
Ascariasis is a nematode (roundworm) and one of the most common human parasitic infections worldwide.
Transmssion occurs via ingestion of contaminated water or food, or less commonly, contaminated soil. Its prevalence
is greatest in tropical climates, with the majority of infections in Asia, Africa, and South America. Often, there are no
symptoms with an A. lumbricoides infection. However, in the case of a particularly bad infection, symptoms may
include bloody sputum, cough, fever, abdominal discomfort, or passing worms. Most diagnoses are made by
identifying the appearance of the worm or eggs in feces. Due to the large quantity of eggs laid, physicians can
diagnose using only one or two fecal smears.
Infections can be treated with drugs called ascaricides. The treatment of choice is mebendazole. The drug
functions by binding to tubulin in the worms' intestinal cells and body-wall muscles.
