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).
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.

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
3. FAST
Minimal amount of fluid in abdomen detectable
by USG ~ 200 - 650ml
High sensitivity in detecting haemoperitoneum
(63 - 100%)
High specificity in detecting haemoperitoneum
(96 - 99%)
Low sensitivity in detecting specific organ lesions
(<50%)
Sensitivity may improve with contrast
4. FAST
4 views
– RUQ
– Pelvis
– LUQ
– Subcostal cardiac - for haemoperitoneum
5. FAST
Posterior peritoneum and reflections, indicating potential
sites of intra-abdominal fluid localization and spread.
6. FAST
4. Cardiac
2. LUQ
1. RUQ
3. Pelvis
Location of probe placement for the trauma examination.
14. Haemoperitoneum - Pelvis
Transverse pelvic view demonstrating a small
amount of blood in the Pelvis
15. Sonographic Pitfalls
Free fluid in pelvis will often be missed
without a full bladder
– Sensitivity improved from 63% to 79% with
full-bladder technique (McGahan et al)
16. Sonographic Pitfalls
Sonography can miss important organ injury that
will require surgery
– Dolich et al reported 43 patients with false-negative
sonographic findings, of which 10 (33%) required
surgery
– Shanmuganathan et al: 467 patients with organ injuries;
157 (34%) had no free fluid on USG; 26 of these 157
required surgery
– USG: triage for unstable patient
– CT still needed if intra-abdominal injury (IAI) is
suspected
17. Sonographic Pitfalls
Sonography is limited or unable to show
certain types of injuries
– Spinal and pelvic fractures
– Diaphragmatic ruptures
– Vascular injuries
– Pancreatic injuries
– Adrenal injuries
– Some bowel and mesenteric injuries
18. Free Fluid Scoring Systems
Huang at al:
– each ‘>2mm fluid pocket’ score 1;
– score > 3 = surgery
McKenney et al:
– vertical height of fluid in cm added
– score > 3 = ↑ need of surgery
19. Free Fluid Scoring Systems
Sirlin et al: fluid in each anatomic region = 1 point
Score IAI (%) Surgery (%)
0 1.4 0.4
1 59 13
2 85 36
3 83 63
Conclusion: an increase in the amount of free fluid
raises the likelihood of major IAI
20. Solid-Organ Injuries
Rothlin et al reported sensitivity of 41.4%
McGahan et al reported sensitivity of 41%
Stengel et al showed that injuries were more
easily detected with a 7.5 MHz linear probe
than with a 3.5 MHz convex probe
21. Solid-Organ Injuries
A diffuse heterogeneous pattern
predominant in splenic lacerations
A discrete hyperechoic pattern most often in
hepatic lacerations
Subcapsular splenic haematomas are shown
as either hyperechoic of hypoechoic rims
Severe kidneys injuries show a completely
disorganized pattern
22. Splenic Laceration
Sonography of LUQ shows splenic lacerations
confirmed by CT
23. Renal Laceration
A renal laceration at the mid-pole of Right Kidney
with huge anterior perinephric haematoma
24. Clinical PEARLS
Trendelenberg’s position
Scan the liver tip for small volume
haemoperitoneum
Repeat the scan if suspicious
Fill the bladder by foley
Lower the gain for pelvic scan
Clot can be echogenic
Look for acute angles = free fluid
25. Paracolic Gutters Views
Time consuming
Skill & experience demanding
Minimal increase in sensitivity
28. What if USG -ve?
Is CT needed?
Sirlin 2002
– 4000 patients
– 3680 USG -ve
– if Fracture or Haematuria → CT
• 11% to OR
– if no Fracture and no Haematuria → no CT
• only 0.1% to OR
31. Additional Utilization
Haemothorax
– anechoic areas above diaphragm
– high sensitivity & specificity
– reverse Trendelenberg or sitting improve
sensitivity
– as little as 20 ml may be detected
34. Additional Utilization
Pneumothorax
– lost of ‘sliding’ sign
– lost of reverberation artifact
– other artifacts: ring-down artifact; ?comet tail
artifact
– M-mode and Power Doppler may help
Rib fracture
– disruption of cortex
