Vision screening is important to identify vision impairments in children so they can receive treatment. Screening should begin at birth and continue at well-child visits. Early screening can detect conditions like amblyopia, which is most effectively treated in early childhood. While only 21% of preschoolers receive vision screening, screening is highly cost-effective for detecting and treating amblyopia and other vision issues. Pediatricians play a key role in regularly screening children's vision as part of comprehensive well-child care.

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
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.

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

Report Back from SGO 2024: What’s the Latest in Cervical Cancer?bkling
Are you curious about what’s new in cervical cancer research or unsure what the findings mean? Join Dr. Emily Ko, a gynecologic oncologist at Penn Medicine, to learn about the latest updates from the Society of Gynecologic Oncology (SGO) 2024 Annual Meeting on Women’s Cancer. Dr. Ko will discuss what the research presented at the conference means for you and answer your questions about the new developments.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
1. Screening
• screening test should be able to quickly
identify a health problem for which a
prevention or treatment is available.
2. Vision screening
• Vision screening is an efficient and cost-
effective method to identify children with
visual impairment or eye conditions that are
likely to lead to visual impairment so that a
referral can be made to an appropriate eye
care professional for further evaluation and
treatment.
3. The Importance of Pediatric Vision Screening
• Amblyopia affects up to 5% of the
population (>10 million Americans).
• In the first 4 decades of life amblyopia
causes more vision loss than all other
ocular diseases combined!
• Amblyopia has a “window period” for treatment
in early childhood.
• Screening can prevent otherwise fatal disorders
such as retinoblastoma.
4. Vision Screening: Scope of Problem
Only 21% of preschool children and even fewer
children below preschool age are screened for
these conditions.
Ottar WL, Scott WE, Holgado SI. Photoscreening for amblyogenic factors. J Pediatr Ophthalmol Strabismus. 1995;32(5):289–295
5. Amblyopia is Very Cost-Effective to Treat
• Membrano, et al: Cost/QALY $2,281 for
Amblyopia Tx
• Comparisons:
– Hypertension screening/therapy in asymptomatic
49 yo = $25,000/QALY
– Annual screening for Diabetic Retinopathy in high
risk diabetics = $41,700/QALY
6. Pediatricians Are the Natural First
Line of Defense – The Medical
Home
• Children already come to Pediatrician.
• Vaccinations and screening are
already a part of care protocol.
• Screening in pediatrics should be
most cost effective (no separate office
visit, no extra-time off work for parent).
6
7. AAP Policy on Vision Screening
• AAP in concert with AAO and AAPOS have a
joint policy statement recommending
screening beginning at birth and throughout
childhood during well child visit.
– Serial screening in the MEDICAL HOME
• Ensures age-appropriate monitoring of visual system.
• Is more efficient and cost effective than comprehensive
eye exams for asymptomatic children.
– Pediatricians are best champions for a child’s
health.
9. Amblyopia…In Other Words:
• The camera (eye) is capable of taking the
picture but the computer (brain) doesn’t
recognize that there is an image.
• “Either use it or lose it!”
10. Children are Different
• Developing cortical connections
• Window of opportunity for diagnosis and
treatment…just like with language development
11. Screen for Causes of Amblyopia
• Refractive errors
• Obstruction of optical pathway (e.g. cataract
or corneal scar)
• Strabismus
• Other—anything that blocks input of
visual information to the brain
12. Motility Terminology
• Strabismus = ocular
misalignment
• Esotropia = eyes turn in
• Exotropia = eyes turn
out
• Hypertropia = one eye
higher than the other
13. When Should We Screen?
• Begin at birth and during all subsequent well
child visits.
– Think of vision screening like vaccinations!
– Different screening at different
developmental/age levels.

15. Age Specific Screening: NEWBORN
• External evaluation for obvious ocular
malformations and infections
– NOTE: Too young to evaluate alignment!!!
• RED REFLEX TEST—preferably prior to
discharge from newborn nursery
– Very important to r/o retinoblastoma or
congenital cataracts
• If congenital cataracts not removed in first 2 to 3
months of life, permanent loss of sight occurs
17. Leukocoria is an Urgency!
Diff Dx include cataract, glaucoma, PHPV,
Retinoblastoma, Retinal detachment, etc.
In addition to sending a consult, CALL
ophthalmologist to make sure the patient is seen
ASAP!

19. Basic Techniques for Examining Children’s Eyes
• Age specific
• Start with HISTORY
– Moms are great diagnosticians!
• Common EXAM components
– Assessment of vision
– External anatomy
– Pupil function
– Motility
– Ocular fundus/Red Reflex
testing
20. Ocular History
• Does child appear to see well distance and
near?
• Any crossing?
• Family history of eye disorders?
• Recurrent discharge or redness?
• Extreme photophobia?
• NOT to worry about:
– “Sits close to TV a lot”
21. External Examination
• Are eyelids symmetric?
• Pupil symmetry?
• Any redness, inflammation, or
discharge?
• Cornea clear?
• Are the eyes aligned?
22. Pupil Exam
• Are the pupils round?
• Symmetric?
– If asymmetric, is it more asymmetric in dark or
light?
• Reactive to light?
23. Motility Assessment
• Is the pupil light
reflex central?
• Do the eyes move
fully in all
directions?
• Pseudostrabismus
vs. true strabismus
25. Vision Assessment
• Infants: Eye contact, follows face, smiles
• Toddlers: Cover each eye and follows
objects (fix and follow)
• Verbal: Visual acuity screening with
appropriate optotype (symbol/letters)
26. Visual Acuity (VA) Testing
• To have good VA both anterior and posterior
visual pathways must be functioning.
• VA testing is the current “gold standard.
• Should be performed at earliest possible
age.
27. Checking VA
The 3 common errors:
• Child peaks.
• Child memorizes.
• Examiner only projects one
letter at time (crowding
phenomenon).
28. AAPOS Vision Screening Kit
• Can order from:
– AAPOS:

b221192
30. New Screening Technology
• Remember in the pre-verbal child, the only
way to detect amblyopia is to indirectly
detect the risk factors.
– Refractive errors
– Media opacities
– Strabismus
34. Photoscreening
• Instrument-based screening is now endorsed
by the as a valid measure for screening
preschool children.
• A randomized controlled multi-centered cross
over study demonstrated photoscreening to
be superior to direct testing of visual acuity
for screening well visit children ages 3–6 in
the pediatrician office.*
• For children older than 5 years, VA testing
still preferred.
35. Summary
• Vision screening should begin at birth and
continue throughout well child visits.
• Vision screening is age-appropriate
– Early Red Reflex testing mandatory
– VA testing in verbal children
• Objective screening technology is effective,
improving, but needs to be reimbursed for
widespread adoption.
• Pediatricians are our best line of defense for
preventable blindness!
