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.

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
Basavarajeeyam is an important text for ayurvedic physician belonging to andhra pradehs. It is a popular compendium in various parts of our country as well as in andhra pradesh. The content of the text was presented in sanskrit and telugu language (Bilingual). One of the most famous book in ayurvedic pharmaceutics and therapeutics. This book contains 25 chapters called as prakaranas. Many rasaoushadis were explained, pioneer of dhatu druti, nadi pareeksha, mutra pareeksha etc. Belongs to the period of 15-16 century. New diseases like upadamsha, phiranga rogas are explained.
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. Contents
– Definition
– Classification
– Indications
– Contraindications
– Materials used
– Soft tissue and esthetic considerations before ridge augmentation procedure
– Techniques
– Techniques used during 1st and 2nd stage implant therapy
3. Definition
– Ridge augmentation is a periodontal procedure used to repair the deficient
edentulous ridge
It can be corrected by
– Hard tissue only
– Soft tissue only
– Soft and hard tissues
4. Classification
Sieberts classification (1983)
– Class 1 – buccolingual loss of tissue with normal ridge height in the apicocoronal direction
– Class 2 - apicocoronal loss of tissue with normal width in the buccolingual direction
– Class 3 – combination buccolingual and apicocoronal loss of tissue, resulting in loss of normal
height and width
Allens classification
– Mild - less than 3 mm reduction
– Morderate - between 3 to 6 mm reduction
– Severe - more than 6 mm reduction
5.
6. Indications
– Deficiency in alveolar ridge due to periodontal disease, loss of teeth, trauma,
neoplasm
– Pronounced concavity and loss of emergence profile in single tooth implant
7. Contraindications
– Systemic conditions – applicable to all surgeries
– Collagen disorders – eg. Lichen planus, pemphigoid. Due to its pathologic
healing mechanism
– Smokers – success of a graft thrives on vascularity. Smoking hampers with the
vascularity of graft due to the vasoconstrictive effect of nicotine
9. Free gingival graft
– First used graft
– Reliable and efficacious
– High and predictable success rate
– Used to increase amount of keratinized tissue (rocuzzo M et al., 2007)
– Gold standard procedure when keratinisation is needed
– Mostly taken from palatal area
– Used as rescue procedures, in place of high smile line, when there is a need for extensive soft tissue augmentation
and where there is no esthetic concern
Disadvantages
– “Patch like appearance” – colour doesn’t blend with the adjacent tissues. Kills the purpose of esthetics
– High morbidity
– Less amount of tissue available
10. Connective tissue graft
– Overcomes the esthetic drawback of FGG. Good colour match
– Gold standard when it comes to recession coverage procedures in esthetic areas
(Imberman M et al., 2007)
– Good vascularity
– Controversy over attachment with implant surface
Drawbacks
– High morbidity
– Lack of adequate tissue in the case of a large defect
11. Allografts
– Commonly used allografts
• Acellular dermal matrix
• Human fibroblast derived dermal derivative
– Low morbidity
– Results in good amount of KT (Hamerle CH et al., 2002)
Disadvantages
– Taken from cadaver specimens – ethical issues
– High risk of disease transmission
12. xenografts
– Commonly used – collagen membrane of porcine origin (Tradename :
MUCOGRAFT™)
– Overcomes the drawbacks of allografts
– Low risk of disease transmission and low morbidity (Jung RE et al., 2011)
– Esthetic results
– Good amount of tissue availability
– Clinical results comparable to gold standard CTG (Barone R et al., 1998)
– Mechanism of action – forms a scaffold into which fibroblasts, blood vessels and
surrounding epithelial cells migrate and transform into KT
13. Soft tissue expanders
– Soft tissue expansion is a technique used by plastic surgeons to cause a body to
grow additional bones, tissues, or skin.
– 2 types
• Silicon balloons
• Osmotic tissue expanders
14. Silicone baloons
– It is costume made according ti the area and expansion needed
– Made of medical grade silicone
– The liquid is injected externally through a liquid processing unit
– Placed under the tissue
– After the volume is achieved it is substituted by graft materials
– Technique sensitive
– Decreased swelling and less discomfort
15. Osmotic tissue expanders
– Self filling
– Made of polymers methyl methacrylate enclosed in a silicone sheathe
– Perforations can be made according to how much expansion is needed
– Absorbs tissue fluid through osmosis and expands
– Requires refining of surgical technique
– Easy augmentation
– High tissue gain
– Need for external filling eliminated
– Minimal complications
16. Soft tissue and esthetic considerations
before ridge augmentation procedures
Rationale
– Transmucosal seal
– Esthetic appearance
– Good emergence profile
– Convexity to simulate root prominence
– To withstand prosthetic mechanical challenge
– Good contour
– Self cleansing
– Withstand recession
17. Biology
periimplant and periodontal mucosa are mostly similar
– contain an epithelial component and connective tissue component
– Contains junctional epithelium
– Collagen type 1 is the predominant fibre in the supracrestal region
– Similar distribution of collagen type 1 3 4 7 and fibronectin (Chavrier CA et al., 1999)
– Less vascular area close to implant analogous to cicatricial fluid (Berglundh T et al., 1996)
– Periimplant tissue similar to scar tissue
Dissimilarities
– Length of junctional epithelium is longer in periimplant mucosa
– Collagen type 5 found to be higher in periimplant tissue (Chavrier CA et al., 1999)
– Fewer fibroblasts in periimplant mucosa than in gingival tissues
– Collagen fibres run parallelly in periimplant mucosa, but attach perpendicular to the cementum in
periodontal mucosa (Berglundh T et al., 1991)
– Periimplant mucosa resembles scar tissue without supracrestal fibres insertion into cementum
18. Biological width
– Bone requires a minimum of 1.5 connective tissue component and 2 mm
epithelial component (Berglundh T et al., 1991, 1994)
– The entire contact length between implant/ cementum, connective tissue and
implant constitute the biological width
– The minimum width is required, failing which the biological width is tried to be
reestablished by bone loss (Berglundh T et al, 1996)
– Same trait is found in loaded and unloaded conditions (Siar CH et al., 2003)
– Same trait is found in both one part and two part implants (Abrahamson I et al.,
1996)
19. Soft tissue health
– Soft tissue integrity is essential before any prosthetic replacement (Kan JY et al., 2003, Zigdon H et
al., 2008)
Soft tissue health is affected by
– Thickness of tissues – different thickness respond differently to inflammation. Thin tissues are more
prone to inflammation and recession (Maynard JG Jr et al., 1979, Kan JY et al., 2003)
– Amount of tissue surrounding bone – a minimum of 2 mm is required to avoid supra crestal bone
loss
– Amount of bone surrounding an implant – 1.8 mm of bone is required to surround an implant (Spray
JR et al., 2000)
– interimplant distance – 3 mm is required (Tarnow DP et al., 2000, 1992)
– Distance between contact area of clinical crown and crestal bone – if its is less than 5mm there will
be 100 percent interdental coverage with papilla formation
– Full thickness flaps amount to an average of 1 mm crestal bone loss in height and width (Cardoropoli
G et al., 2006)
20. Keratinized tissue
– Adequate Keratinized tissue is a requirement for any prosthetic procedure
– KT is a dense, collagen rich tissue with keratinised with firm attachment of underlying lamina propria to the bone (Ten Cate AR AR
Oral histology development structure and function)
– Alveolar Mucosa is less dense, with less collagen tissue with non keratinised epithelium with loose attachment to the muscles
underneath
– KT is required to resist recession, inflammation. Greater keratinised tissue around a prosthesis gives greater clinical parameters and
better longterm prognosis and maintenance of the prosthesis (Adibrad M et al., 2009, Thoma DS et al., 2014)
– Lining mucosa is more prone to detachment, recession and inflammation. Reduced with of KT indicates shallow vestibule, thus leads
to plaque accumulation and inflammation
– In patients with good oral hygiene, less than 2 mm width of attached gingiva caused lingual plaque accumulation, bleeding and soft
tissue recession over a period of 5 years (Schrott AR et al., 2009)
– Adequately keratinized zone of masticatory mucosa for good oral heath is <2mm of masticatory gingiva and >1mm of attached
gingiva in 5 years (Chung DM et al., 2006)
– KT should be created with mucogingival techniques prior to implant placement if not present in adequate amounts (Wennstrom JL
et al., 2012)
– Importance of KT is controversial. (Karring T et al., 1971, Wenstrom J et al., 1983) It may not be crucial for maintenance of soft tissue
health (Cairo F et al., 2007) and bone loss (Chung DM et al 2006)
21. Mucosal thickness
– A minimum of 3 mm mucosa. Otherwise bone loss occurs to compensate the
biological width
– Linkeviscious et al., in his study found that bone loss was greater (1.45mm) in
subjects with thin gingival biotype (<2.5mm) than in subjects with thick biotypes
(>2.5mm).
– “Black triangle” causes difficulty in phonetics, food accumulation and unpleasant
esthetic (Chow YC et al., 2010)
– Greater than 2.5 mm thickness of gingiva warranted better formation of soft tissue
contour and papilla
– It also depended on interdental distance, distance from crest to contact area, tooth
form and contour, mucosal thickness, amount of KT
22. Abutment material
– Titanium has always traditionally been used as the gold standard for its well
documented biocompatibility and mechanical properties
– Abbrahamson et al analysed the soft tissue healing and has shown that titanium
and ceramic promotes good soft tissue attachment whereas gold alloy and
porcelain failed to promote soft tissue attachment. But there was no difference
in terms of microbial sampling
23. Crest module and abutment
design/surface
– Crest module is the part of implant that receives crestal stress of implant after
loading
– It was found that irrespective of its distance from the crest, the crestal bone
loss reached till the first thread of implant (Jung YC et al., 1996)
– Hypothesis - The change from sheer force to compressive force by the crest
module caused the bone loss to slow down at that area (Jung YC et al., 1996)
– In an animal study, Micro grooved design showed better soft tissue response
and bone implant contact than micro textures and turned surface
– Pacora et al in a 3 year post operative result reported that Laser lock surface
treatment reduces crestal bone loss by 0.59 mm
24. Pink/ White esthetic score
– Can be Used to measure the esthetic value of a prosthesis (Cosyn J et al., 2013)
– The soft tissue color blend, contour, formation of interdental papilla, and
coverage of recession contributes to the esthetic value of a soft issue procedure
– Esthetic outcome is vital for clinical outcome (Cosyn J et al., 2013)
– CTG is required in 1/3rd patients undergoing prosthetic management to increase
PES score (Gu YX et al, 2015)
– Soft tissue augmentation in the second stage of the implant increases PES score
in short term follow up but reverts back when observed for 3 years (Dorfman HS
et al., 1982)
25. Soft tissue healing
– Graft uptake and healing requires 6 to 8 weeks
– The graft after healing and taking up post surgery mimics the gingival scar tissue
in composition, fiber orientation and vasculature
27. – Meltzer 1979 published first clinical report
– To correct esthetic anterior vertical ridge defect
– Siebert 1983 published a series of classic articles that detail the technique and
applications
Full thickness soft tissue onlay
graft
28.
29. Pouch procedure
– Garber and Roenberg 1981 developed this technique
– For treating ridges that had a horizontal loss o dimension
– Provides stabilisation of graft and ridge enhancement
– It is a refinement and advancement of the technique devised by langer and
abrams
30.
31. Ridge augmentation - Improved
technique
– In 1985, allen and colleagues improved a surgical technique for localised ridge
augmentation that was similar to the technique by kahldahl and colleagues
1982 except that the graft material was HA graft
– It permits unlimited donor source
– Greater predictability of results
32.
33. – Langer and calagna 1980 1982 designed a procedure that combined partial thickness flap anda connective tissue graft.
Advantages
– Versatility
– Primary closure
– Vascularity
– Combined with adjacent root coverage procedures
– Reduced trauma
Disadvantages
– Technically difficult
– Possible need for secondary mucogingival surgery owing to altered coronal position of mucogingival junction
Indication
– For correction of all types of ridge deformitues
Subepithelial connective tissue
graft
34.
35. – Its is given by siebert 1992
– Almost identical to the pouch procedure
– except that a thick connective tissue graft or wedge is positioned between the
free edge of the pouch and the exposed portion of t he ridge
– Used for treatment of class 1 ridge defects
Interpositional graft
36.
37. – Siebert and Louis 1995 96 developed this procedure
– For large class 3 ridge defects
– Meant to combine the best procedures of the interpositional graft and the onlay graft into one procedure
Advantages
– Increased revascularization of onlay graft
– smaller platal wound
– Less morbidity
– Increased ability to control direction of augmentation
• Apicocoronal
• Buccolingual
– No alteration in vestibular depth
Interpositional onlay graft
38.
39. – Papillary reconstruction is unpredictable with minimum results
– Most reports are in the form of individual case reports (takkei 1996, azzi and
colleugues 1999 2001)
– Neurovsky 2001 presented a case series with consistent improvement
– All procedures are the modification of the takei 1996 procdure
Azzi modification
40.
41. – It si a vascularised subepithelial connective tissue graft designed for esthetic reidge augmentation befire, during and after implant placement
– Will help prevent premature membrane exposure
– Provide sufficient additional vascularized tissue
– For vertical and buccal ridge augmentation
– Involves passive rotation of an interpositional periosteal retained connective tissue flap over the edentulous area into the buccal surface
Advantages
– Maintains intact vascular supply
– Allows large volume of soft tissue augmentation
– Excellent esthetic results
– Minimum post surgical shrinkage
– Primary wound closure
– Reduced morbidity
– Enhanced bone graft maturation
– Predicatble implant site development
Requirements
