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

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
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

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.

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.

3. Men’s fertility potential depends on
female factors
• Assessment of tests and treatments for the male is
challenging due to inconsistent endpoints and the
observation that many of these endpoints are
dependent upon and measured from the female
partner.
• Ideally, the endpoint for fertility trials should be "live
birth or cumulative live birth (WHO, 2021)
8. Limitations of WHO Guideline
• 5 percentile and time-to-pregnancy (TTP) concept
• Not true reference values but recommends
acceptable levels.
• Day to day variation
• Functional ability of the sperms?
9. Sperm DNA
Fragmentation (SDF)
Infertile men with:
• Repeated IUI or IVF failure
• Recurrent spontaneous
miscarriages (ESHRE, 2018)
• Previous low fertilization,
cleavage or blastulation rate
• Varicocele with
normozoospermia
• Advanced male age (>40 y)
Significance of SDF
• Live birth after IUI/ IVF/
ICSI- ?
• Oocytes can repair the
damaged DNA
• Lack of standardization
• Lack of definitive treatment

subfertility
• Lifestyle
• Occupation- Driving, IT, chemical industry (heavy
metal, pesticides)
• Medical history- Diabetes, Mumps, Cancer
• Surgical history- Hernia, Orchidopexy, Pituitary
Surgery, Bladder neck surgery
• Drug history- Sulphasalazine, Finesteride,
cytotoxic drugs, steroids
• Sexual history- Low libido, ED
25. Darren et al. Male infertility – The other side of the equation . 2017
26. Varicocele- always CLINICAL Diagnosis (EUA,
2018)
• Subclinical: not palpable or
visible, but can be shown by
special tests (Doppler
ultrasound).
• Grade 1: palpable during
Valsava manoeuvre, but not
otherwise.
• Grade 2: palpable at rest, but
not visible.
• Grade 3: visible at rest
27. Surgery for Varicocele
(EUA, 2018)
• Grade 3 varicocele
• Ipsilateral testicular atrophy
• Pain
• Abnormal semen parameters
• No other fertility factors in the couple
28. Do you recommend varicocelectomy here?
• 35 yr- Azoospermia
• Lt undescended testis
• 19 yr age- Lt orchidopexy
• 21 yr age- left testicular cancer
(mixed germ cell Tx)→
orchidectomy, f/b 3 cycles of
chemotherapy (BPC)
• 33 yr age-Papillary Ca Thyroid→
Total thyroidectomy and neck LN
dissection f/b Radio-iodine. Now
on Eltroxin 150
• FSH 27.14, LH 6.69, Testosterone
336 ng/dl, E2 26.0 pg/ml.
• Female age 35
29. In couples seeking fertility with ART, varicocele repair
• may offer improvement in semen parameters
• may decrease level of ART needed
30. Cryptorchidism in adults (EUA, 2018)
• In adulthood, a palpable undescended
testis should NOT be removed because it
still produces testosterone.
• Correction of B/L cryptorchidism, even in
adulthood, can lead to sperm production in
previously azoospermic men
• Perform testicular biopsy at the time of
orchidopexy in adult- to detect germ cell
neoplasia in situ
31. Cryptorchidism- bilateral in adults?
• 31 yr
• Azoospermia
• USG- Rt testis in lower abdomen, Lt testis in inguinal canal
• FSH 13.40. LH 6.87. Testo 6.89. E2 <10.
34. Importance of history and examination
Rt sided orchidopexy during appendicectomy at 18 yr
Subsequently Rt testis atrophied
Lt side operated after 6 months, could not be brought to scrotum,
biopsied, seen by MRI (not seen in USG)
35. Learning from mistake
• Secondary anejaculation and ED
• B/L abdominal testes
• 3 yr age- attempted Rt orchidopexy but
failed
• 13 yr age- Left sided orchidopexy
attempted but partial success.
• 32 yr age- B/L orchidectomy after
failed orchidopexy attempt
• 35 yr
• Left cryptorchidism (abdominal testis)
• Lt orchidectomy at 12 yr
• Testicular prosthesis
• Azoospermia
36. Imaging
Scrotal ultrasound
1. Clinically abnormal findings-
mass/ atrophy
2. Tight scrotum (Cremasteric
reflex)
3. Obese patient
• NOT for Varicocele detection
• NOT the replacement for
clinical examination
(EUA, 2018; ASRM, 2020)
Transrectal ultrasound (TRUS)
1. Low volume and pH of semen
2. Ejaculatory disorders
(EUA, 2018; ASRM, 2020)
38. Hormone Evaluation
Sperm concentration <10 million/ml
Sexual dysfunction
Clinically suspected endocrinopathy
FSH, LH, testosterone, HbA1C
FSH, LH low
Testosterone low
Hypogonadotropic hypodonadism
Pituitary imaging
hCG f/b hMG
therapy
for 6-24 months

40. TMSC PR/CYCLE
10–20 million 18.29%
5–10 million 5.63%
<5million 2.7%
Guven et al, 2008;Abdelkader & Yeh, 2009

EUA, 2018; ASRM, 2020; Vignera et al., J Med Microbiology, 2014
• The clinical significance is controversial.
• Special Tests- Round cells vs Pus cells
• Method of collection
• Hand washing before collection
• Culture of semen
• Antibiotics- only when documented infections
• Routine antibiotics- can harm
• Consider prostatic fluid culture
• NAAT for Chlamydia and gonorrhoea

93. Non-targeted investigations ?
• Delayed puberty
• Testo 100.86. FSH 28.33. LH 13.65. E2 27.83
• Testosterone injection started at puberty - sec sex charac, voice, genital size
improved
• MRI pitutary microadenoma
• GH, TSH, Cortisol, PRL, - all normal
94. Targeted female investigations
• If no risk factors for
tubal block- 3 cycles of
IUI, then tubal patency
test
• If risk factors- tubal
patency first
•Ovaries
•Tubes- IUI or IVF/ICSI?
95. Meticulous semen analysis in a standard laboratory
History and Physical examination
Rational use of Hormones, Imaging, Genetic testing
Avoid non-evidence based drugs for long time
Antioxidants- May be useful in mild problem
Antioxidants- Not reliable in severe problem
Donor sperm is NOT the only solution
IUI or IVF/ICSI- depends on the overall assessment
