The aging process causes changes in both individual cells and organ systems over time through a combination of genetic and environmental factors. As we age, cells multiply more slowly, immune function decreases, and the process of cell death is disrupted. Bodily changes include loss of height from spinal compression, increased body fat and weight until mid-life, and altered drug processing. While some organ function declines gradually, normal aging itself is generally benign, though disease risks increase and individual aging rates vary.
As person get older, many health problems become more likely to pass, including problems that bear on the body and brain. And though some of these problems are unavoidable, becoming a senior citizen does not doom someone to a life of wellness troubles. to avoid this, here is summary of several steps that can be taken in prosperous age to avoid later health problems.

Unit vi ageing process and physiological changes m.sc ii yrsanjalatchi
Normal ageing is characterised by a decrease in bone and muscle mass and an increase in adiposity . A decline in muscle mass and a reduction in muscle strength lead to risk of fractures, frailty, reduction in the quality of life and loss of independence [45]. These changes in musculoskeletal system reflect the ageing process as well as consequences of a reduced physical activity. The muscle wasting in frail older persons is termed ‘sarcopaenia’. This disorder leads to a higher incidence of falls and fractures and a functional decline. Functional sarcopaenia or age-related musculoskeletal changes affect 7% of elderly above the age of 70 years, and the rate of deterioration increases with time, affecting over 20% of the elderly by the age of 80 Strength declines at 1.5% per year, and this accelerates to as much as 3% per year after 60 years of age . These rates were considered high in sedentary individuals and twice as high in men as compared with those in women . However, studies show that on an average, men have larger amounts of muscle mass and a shorter survival than women. This makes sarcopaenia potentially a greater public health concern among women than among men

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
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.

Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
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

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!

2. THE AGING PROCESS
As we age, our bodies change in many ways that affect the function of both
individual cells and organ systems. These changes occur little by little and
progress inevitably over time. However, the rate of this progression can be
very different from person to person. Research in aging is beginning to find
out the reasons for these changes and the genetic and environmental factors
that control them.
– Genetic and Environmental Factors
• Healthy Lifestyle Behaviors
–
–
Cellular Changes Associated with Aging
Bodily Changes Associated with Aging
• Changes in Height
• Changes in Weight
• Changes in Body Composition
– Other Changes with Aging
• Normal Aging and Disease
• Changes in the Regulation of Body Systems
3. Genetic and Environmental Factors
The aging process depends on a combination of both
genetic and environmental factors. Recognizing that
every individual has his or her own unique genetic
makeup and environment, which interact with each
other, helps us understand why the aging process can
occur at such different rates in different people.
Overall, genetic factors seem to be more powerful than
environmental factors in determining the large
differences among people in aging and lifespan.
4. Behaviors of a Healthy Lifestyle
– Not smoking
– Drinking alcohol in moderation
– Exercising
– Getting adequate rest
– Eating a diet high in fruits and vegetables
– Coping with stress
– Having a positive outlook
5. Cellular Changes Associated with Aging
Aging causes functional changes in cells. For
example, the rate at which cells multiply tends
to slow down as we age. Certain cells that are
important for our immune system to work
properly (called T-cell lymphocytes) also
decrease with age. In addition, age causes
changes in our responses to environmental
stresses or exposures, such as ultraviolet light,
heat, not enough oxygen, poor nutrition, and
toxins (poisons) among others.
6. Age also interferes with an important
process called apoptosis, which programs
cells to self-destruct or die at appropriate
times. This process is necessary for tissues
to remain healthy, and it is especially
important in slowing down immune
responses once an infection has been
cleared from the body.
7. Different diseases that are common in elderly people can
affect this process in different ways. For example, cancer
results in a loss of apoptosis. The cancer cells continue to
multiply and invade or take over surrounding tissue,
instead of dying as originally programmed. Other diseases
may cause cells to die too early. In Alzheimer’s disease, a
substance called amyloid builds up and causes the early
death of brain cells, which results in a progressive loss of
memory and other brain functions. Toxins produced as
byproducts of nerve-cell transmissions are also thought to
be involved in the death of nerve cells in Parkinson’s
disease.
8. Bodily Changes Associated with Aging
Our bodies normally change in appearance as
we age.
Changes in Height
We all lose height as we age, although when the
height loss begins and how quickly it progresses
vary quite a bit among different people.
Generally, our height increases until our late
forties and then decreases about two inches by
age 80. The reasons for height loss include the
following:
9. changes in posture
changes in the growth of vertebrae (the bones that make up
the spine)
a forward bending of the spine
compression of the discs between the vertebrae
increased curvature of the hips and knees
decreased joint space in the trunk and extremities
joint changes in the feet
flattening of the arches
The length of the bones in our legs does not change much.
10. Changes in Weight
In men, body weight generally increases until their mid-
fifties; then it decreases, with weight being lost faster in
their late sixties and seventies. In women, body weight
increases until the late sixties and then decreases at a rate
slower than that of men.
People that live in less technologically developed societies
do not show this pattern of weight change. This suggests
that reduced physical activity and changes in eating habits
may be causes of the change in body weight rather than the
aging process.
11. Changes in Body Composition
The proportion of the body that is made up of fat doubles
between age 25 and age 75. Exercise programs may
prevent or reverse much of the proportional decrease in
muscle mass and increase in total body fat. This change in
body composition is important to consider in nutritional
planning and level of activity. The change in body
composition also has an important effect on how the body
handles various drugs. For example, when our body fat
increases, drugs that are dissolved in fatty tissues remain
in the body much longer than when our body was younger
and more muscular
12. Other Changes with Aging
Normal aging in the absence of disease is a
remarkably benign process. In other words,
our body can remain healthy as we age.
Although our organs may gradually lose some
function, we may not even notice these changes
except during periods of great exertion or
stress. We may also experience slower reaction
times.
13. Normal Aging and Disease
Aging and disease are related in subtle and
complex ways. Several conditions that were once
thought to be part of normal aging have now been
shown to be due to disease processes that can be
influenced by lifestyle. For example, heart and
blood vessel diseases are more common in people
who eat a lot of meat and fat. Similarly, cataract
formation in the eye largely depends on the
amount of exposure to direct sunlight.
14. We should remember that there is a range of
individual response to aging. Biologic and
chronologic ages are not the same. In addition,
body systems do not age at the same rate within
any individual. For example, you might have
severe arthritis or loss of vision while the function
of your heart or kidneys is excellent. Even those
aging changes that are considered "usual" or
"normal" are not inevitable consequences of
aging.
