RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

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.

2. What is Computer Vision Syndrome (CVS)?
Computer Vision Syndrome
(CVS) is the general term
used to describe a variety of
vision related symptoms
that may be aggravated by
regular use of a computer
for two or more hours a day.
3. Who is at risk for CVS?
According to AOA (American Optometric
Association), anyone who exceeds two hours of
computer use a day is at a risk for CVS.
(In the US, more than 70 percent of the
approximately 143 million Americans who work on
a computer on a daily basis)
6. What causes these symptoms?
• Characters (pixels) on computer screen do not
have well defined edges. They are brightest at
the center and diminish in intensity towards the
edges.
• This makes it very difficult for eyes to maintain
focus.
• Extensive focusing does not give much
opportunity to the eye muscles to move and this
leads to eye strain, burning,
tired – eyes feeling.
7. Other contributing factors
• Constant gazing at a near distance at the
monitor (which leads to convergence fatigue).
• Fixed posture while working long hours
• The eye muscles do not get much opportunity
to move.
• Uncorrected visual defects
• Glare from lighting in the work place and
direct light coming in from the exterior
8. Infrequent blinking
• Normally a person blinks 15 times/min, but
while working on a computer, the blink rate
comes down to 5 times /min because of
continuous staring at the screen.
• Blinking is critically important for spreading of
tears to form an even film on the eye surface
and also in refreshing this tear film.
• Thus in the absence of adequate blinking,
eyes become dry and irritated.
10. What can be done : 5 Es
• Examination
• Ergonomics
• Exercises
• Effective breaks
• Eye wear
11. Eye Examination
This is the most important thing you can do to
prevent or treat computer vision problems.
According to the National Institute of
Occupational Safety and Health (NIOSH),
computer users should have an eye exam
before they start working on a computer and
once a year thereafter. Be sure to tell your
eye doctor how often you use a computer at
work and at home.
12. Eye Exercises
To reduce your risk of tiring your eyes by constantly
focusing on your screen, look away from your computer
every 20 minutes and gaze at a distant object outside or
down the hallway. Looking far away relaxes the focusing
muscles inside the eye to reduce fatigue.
Another exercise is to look far away at an object for 10-15
seconds, then gaze at something up close for 10-15
seconds. Then look back at the distant object. Do this 10
times. This exercise reduces the risk of your eyes' focusing
ability to "lock up" (a condition called accommodative
spasm) after prolonged computer work.
Both of these exercises will reduce your risk of computer P.S: Blink - not to be
eye strain. Remember also to blink frequently during the confused with Wink…
exercises to reduce your risk of computer-related dry eye.
13. Ergonomics- Screen to eye distance
The screen should be at a
distance of 16-30 inches
from the eyes
14. Ergonomics-Adjusting height of the seat
Adjust the height of the
desk or chair so that the
middle of the computer
screen is about 20
degrees below eye level.
15. Ergonomics-Minimize glare
• Direct the overhead lights
away from computer
screens
• Position your monitor so
that all windows are to the
side rather than to the
back or front.
• Adjust window blinds so
that sunlight is away from
screen and your eyes.
Install an anti-glare optically
coated glass
filter on the computer screen
16. Eyewear -Computer glasses
• These glasses have a special tint that
reduces glare and the intensity of the light
produced by an average computer
monitor. They also feature a special UV
coating that blocks UV rays produced by
monitors and fluorescent lighting.
• These glasses are designed for people
who don't need vision correction or who
wear contact lenses to correct their vision.
• But be aware that tints alone don't address
the underlying cause of computer
eyestrain, which is focusing fatigue.
17. Eyecare -Use lubricating eye drops
• Lubricating eye drops are meant to provide
moisturizing relief to your eyes, which have
become dry and irritated by working for long
hours on the computer.
• Lubricating eye drops help in soothing the
eyes and relieving irritation, redness & the
eyestrain.
• Lubricating eye drops can be used as often
as you want, especially the newer ones,
which are safe to the eye enabling their
frequent use.
18. Effective short breaks
Computer users can reduce
fatigue by taking breaks
from work and can benefit
from taking a five minutes
break for every 30 minutes
of work.
