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!

Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.

Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

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
Couples presenting to the infertility clinic- Do they really have infertility...Sujoy Dasgupta
Dr Sujoy Dasgupta presented the study on "Couples presenting to the infertility clinic- Do they really have infertility? – The unexplored stories of non-consummation" in the 13th Congress of the Asia Pacific Initiative on Reproduction (ASPIRE 2024) at Manila on 24 May, 2024.
2. OVERVIEW
A pulmonary embolism (PE) is a potentially life-threatening
medical emergency which often presents with very few clinical
signs or symptoms.
PARTIAL PE / TOTAL PE
THERE ARE SEVERAL TYPES OF EMBOLI THAT DEPEND ON THE
SITE WHICH IS FORMED IN
3. CASE STUDY
A 65-year-old man presents to the emergency department with acute onset of shortness of breath of 30
minutes' duration. Initially, he felt faint but did not lose consciousness. He is complaining of left-sided
chest pain that worsens on deep inspiration. He has no history of cardiopulmonary disease. A week ago
he underwent a total left hip replacement and, following discharge, was on bed rest for 3 days due to
poorly controlled pain. He subsequently noticed swelling in his left calf, which is tender on examination.
His vital signs revealed a fever of 38.0°C (100.4°F), heart rate 112 bpm, BP 95/65 mmHg, RR 24-28 and an
O₂ saturation on room air of 91%
4. RISK FACTORS
a) VENOUSE STASIS : (eg, bed rest >48 hours, long-distance auto or air travel, recent hospitalization)
b) ALTERATIONS IN COAGULATION ( eg, malignancy, previous PE/DVT, pregnancy, or protein C deficiency)
c) VASECULAR INJURY (eg, trauma, recent surgery, central lines, IV drug use)
A provoked PE refers
to a PE developing in an
individual who has
recognised risk factors
for PE.
An unprovoked
PE refers to a PE
developing in an
individual with no
known underlying risk
factors.
5. CLINICAL MANIFISTATION
Shortness of breath (DYSPNEA )
Pleuritic chest pain: with each breath, the pleura comes into contact with an ischaemic area of the lung.
Cough
Haemoptysis: secondary to infarcted lung tissue.
Dizziness or syncope: due to haemodynamic instability (i.e. right ventricular strain).
SYMPTOMS
6. CLINICAL MANIFISTATION
Tachypnoea: a respiratory rate of more than 20 breaths per minute.
Tachycardia: a heart rate of more than 100 beats per minute.
Hypotension: suggestive of right ventricular strain.
Evidence of deep vein thrombosis (DVT) such as a red, swollen calf.
Pleural rub: a squeaking or grating sound caused by ischaemic lung tissue coming in contact with the
pleura.
Cyanosis: a late sign that indicates a significant drop in blood oxygen levels (SpO2)
Signs
7. (PE) APPROACH
CT-ANGIO :is the accepted diagnostic modality of choice , It is rapid and sensitive for detecting proximal PE
ABG
V/Q scan : this test is infrequently used today except , when specific contraindications to a CTA exist, Although previously favored
for pregnant patients, guidelines now typically recommend CTA in pregnant patients
D-Dimer: fibrin degradation product that circulates in a patient with a dissolving fibrin thrombus. I t is found in the serum within 1
hour and stops circulating after 7 days
ECG: useful t o rule out a primary cardiac etiology , The classic S 1 Q3T3 combination of findings (S wave in lead I, Q wave in lead
III, and T wave inversion in lead III) is present in <20% of patient with confirmed PE. Right-sided heart strain seen as T-wave
inversions in the anterior leads (v1-v4) may be present in massive PE
CXR : evaluating other causes of the symptoms. In PE, CXR is nonspecific and nondiagnostic, with a normal radiograph
DOPPLAR ULTRASOUND : used to diagnose DVT in a patient with a high clinical suspicion of PE and a negative CTA.
Troponin : to screen for myocardial damage which may be due to acute coronary syndrome or secondary to PE (due to right heart
strain and prolonged tachycardia).
