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
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

2. What we will cover
• How OCT works
• Layers of the retina
• 3D OCT Tips
• Healthy retina architecture
• Pathology
• Q&A
3. Seeing better with OCT
Light passing through
tissue is delayed
before it is reflected
back to the
camera
Measurement of this
‘delay’ provides
cross-sectional
information about the
structure of the tissue
being imaged
OCT is able to see the intricate and delicate layers of the
retina, optic nerve and other ocular tissues (e.g. the RPE).
8. • Trade off of scanning
area vs. image quality
• Typical Pre sets
– 8.2 mm x 3 mm @ 1,024 x
32 b scans (better image)
– 6 mm x 6 mm box @ 512
x 128 b scans (better
coverage)
Scanning Protocol
9. Patient preparation
• Pupil size
– Min pupil size is 3.7 mm
– Slightly dilated pupils will improve OCT and fundus image
quality
• Dry cornea
– A dry cornea will reduce the OCT image quality
– Make sure that your technicians tell the patient to blink
before the capture procedure
– Use drops if needed
• Fixation
10. Viewing Techniques
• View in Black and White
to provide better
contrast
• Use OCT image
adjustment bar
16. Pathology
• Reported incidence of pathology detected with
Topcon 3D OCT in a Lasik population during pre-
treatment evaluation was 1.6%
• Typical pathologies
– Epiretinal membrane
– Drusen
– Macular Edema
– Hard Exudates
– Macular Holes
– Vitromacular Traction
17. Epiretinal Membrane
• Incidence is 6% of patients over 60 yrs*.
• Appearance
– Rippling of ILM which can extend over the fovea resulting
of the loss of the normal foveal contour.
*Source: Optical Coherence Tomography of Ocular Diseases,
Schuman, JA, et al, 2004
22. Drusen
• Reported incidence of drusen in patients 43 to 54
was 2.2% (soft) and 3.3% (large)*
• Appearance
– Localized highly reflective area under Bruch’s membrane,
you may also see a slight flattening of the foveal contour.
*Source: Beaver Dam Eye Study
Ophthalmology. 2003 Oct: 109 (10): 1767-79.
27. Macular Edema
• Appearance
– Hypo echoic areas in the retina. Can be associated with
Diabetes (Diabetic Macular Edema- DME), cystic in
appearance (Cystoid Macular Edema- CME)
30. Hard Exudates
• Can be seen in any conditions that are associated
with vascular leakage
– Diabetic retinopathy
– Hypertensive retinopathy
• Appearance
– Focal hyper echoic areas in the ONL
32. Macular Holes
• Extremely rare in patients under except you can see
in the case of trauma. Various types
– Lamellar (partial macular hole)
– Full thickness macular hole
• Appearance
– Lamellar hole- pit/opening from ILM but not down to the RPE
– Full thickness macular hole- Opening down to the RPE, volcano
appeareance
