During this webinar Sophie Tully BSc MSc DipPT will discuss why nutrition research often fails to produce positive results and the methodological flaws that contribute to poor research outcomes.
Sophie will provide a detailed explanation of what we can learn from the recent wave of negative nutrition research and how to carefully consider and determine the right supplement regime for your clients’ health concerns. Covering the most important factors to consider when choosing the nutrients, dose and timescale of a nutritional intervention Sophie will provide you with a practical clinical toolkit that can be applied to all of your protocols to ensure client success.
During this webinar Dr Bailey reviews the latest evidence for the clinical application of omega-3 fats found in fish oil with a focus on choosing the best source, form, bioavailability and strength for your client’s condition management.
Stress and anxiety are common experiences for most people. In fact, 70% of adults in the United States say they feel stress or anxiety daily. These stress and anxiety give rise to unnecessary health diseases like impotence, take help of Filagra Oral Jelly Butterscotch Flavor.
In this informative webinar, with expert nutritionist Dr Nina Bailey, you will learn about how we can optimise our diet to help manage many of the symptoms associated with CFS/ME, namely lack of energy, extreme fatigue and ‘brain fog’:
Foods the brain and body needs to function optimally: what we should be eating
Foods that starve the brain and body of nutrients and energy: what foods we really need to avoid
Supplements: the best nutrients for providing energy and treating symptoms associated with CFS/ME, backed up by science
By making some relatively simple dietary changes that may, in some cases, include the use of dietary supplements, it is possible to see significant improvement in symptoms.
Advanced nutrition for the brain series: stress, the HPA-axis and neuroinflammation. Targeted nutritional interventions for successful treatment of mental health conditions.
Inflammation is a major contributing factor to chronic modern illness and is driven, in part, by chronic stress and HPA-axis over stimulation. Mental health conditions, in particular clinical depression, are increasingly linked with neuroinflammation. As such, anti-inflammatory interventions are known to result in significant clinical benefits.
During this webinar Dr Bailey will discuss the biological mechanisms linking stress, chronic inflammation and mood disorders, together with a review of the current evidence for a targeted, anti-inflammatory nutrition approach to treatment. Nina will also clarify why some of the recent trials have failed to report benefits and how to optimise your anti-inflammatory interventions to treat clients with anxiety, depression, schizophrenia and PTSD.

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

3. evidence-based alternative therapies
omega-3 fatty acids and sam-e
Exercise and a healthy diet have long been recognized as important adjuncts to talk therapy and drug
therapy for the treatment of mental illness. Recently, omega-3 fatty acids (primarily from fish oil and
flaxseed oil) and s-adenosylmethionine (SAM-e) have been used to treat symptoms of mental illness,
particularly depression. An evidence base now is being developed for these two “alternative” remedies.
A recent article by Adriane Fugh-Berman, M.D. and Jerry M. Cott, Ph.D. has documented the current
evidence base for the use of alternative therapies for mental illness.1 Since alternative remedies are
used by about half of mental health consumers, it is essential that this information be widely dissemi-
nated so that consumers and families affected by mental illness and providers of mental health care
can properly discuss and evaluate these alternatives as part of the treatment dialogue.
The alternative therapies which Fugh-Berman and Cott recognized as evidence-based for treatment of
mental illness were:
• St. John’s wort (hypericum perforatum) for depression.
• Ginkgo (ginkgo biloba) for mild dementia.
1
4. • Kava (piper methysticum) for anxiety and stress.
• Valerian (valeriana officinalis) for insomnia and stress.
• Omega-3 essential fatty acids (fish oil and flaxseed oil), for major depression, bipolar disorder,
and other psychiatric disorders.
• S-adenosylmethionine (SAM-e) for depression.
• Folate, tryptophan and phenylalanine to enhance the effectiveness of conventional anti-
depressants.
The article concluded that, although the effects of herbal therapies are milder than many prescription
medications, there is a substantial evidence base for the use of St. John’s wort, ginkgo, kava and valer-
ian, for relief of some symptoms of mental illness and for some people. In a 2000 pamphlet, the
National Association of Mental Health Planning and Advisory Councils (NAMHPAC) described the evi-
dence base for these herbal therapies. A recent JAMA-reported study (Shelton, et al., 2001)2 found a
minimum treatment effect for St. John’s wort in chronic, severe depression. However, there is strong
evidence of its effectiveness in mild to moderate depression. Ongoing studies should help resolve the
controversy. Evidence for the use of the remaining listed alternative therapies is promising, but not yet
as strong. Evidence for omega-3 fatty acids and SAM-e is summarized in this pamphlet. The other
alternative therapies evaluated but not found to be evidence-based at this time for treatment of men-
tal illness included: ginseng, passion flower, skullcap and mega-vitamins.

5. This pamphlet is not intended to encourage
the use of alternative therapies for mental ill-
ness. However, since many users of alternative
therapies do not inform their physicians of
their use, this pamphlet is intended to help
open a dialogue between consumers and fami-
lies affected by mental illness and providers of
mental health care, based on the evidence that
is now available. Counseling about side effects
and herb-drug interactions is very important to
avoid potential trouble. Based on the evidence
now available, physicians should be prepared
to discuss use of omega-3 fatty acids and
SAM-e with persons and families affected by
mental illness. Consumer autonomy and family
responsiveness are best fostered in an atmos-
phere of understanding and candor.

7. Omega-3 fatty acids
Because of the concern about the health effects of excessive consumption of fats, we have for too
long ignored the critical function of the essential fatty acid (omega-3/omega-6) balance in our diet.
This balance of essential fatty acids is necessary to regulate the cell membranes in our bodies, and par-
ticularly our brains, which are composed of 60% fat. This pamphlet seeks to summarize important
recent studies suggesting that additional ingestion of omega-3 essential fatty acids may be an impor-
tant remedy to the detrimental dietary changes that have come about in recent years. These changes
have emphasized omega-6 and partially hydrogenated (trans-) fat consumption and may have made
modern societies more prone to serious mental illness as a result.
This research is still ongoing, and these conclusions are not universally accepted. This pamphlet should
not be read as making such a claim. However, Andrew L. Stoll, M.D., Director, Psychopharmacology
Research Laboratory, McClean Hospital Faculty, Harvard Medical School, recently asserted in his
groundbreaking and comprehensive book, The Omega-3 Connection (Simon & Schuster, New York
2001), “we are learning that restoring the body’s natural balance of omega-3 oils may improve a mul-
titude of medical disorders, including coronary artery disease, major depression, and bipolar disorder
(also called manic-depressive illness).” Stoll added that: “other research suggests that omega-3 fatty
acids may yield new treatments for postpartum depression, schizophrenia, [and] attention deficit-
5
8. hyperactivity disorder.... Furthermore, it is possible that omega-3 fatty acids may actually prevent these
disorders from developing as well.”3
The National Institutes of Health convened a 1998 conference on “Omega-3 Essential Fatty Acids and
Psychiatric Disorders” (see http://nimh.nih.gov/events/omega.htm). Although the NIH was careful not
to express an opinion, eminent researchers from a range of disciplines unanimously supported lowering
the ratio of omega-6 to omega-3 fatty acids (currently as much as 25:1 in American diets) to promote
optimum health and linked psychiatric disorders to relative omega-3 deficits.
a short course in lipids
Fatty acids are a primary portion of human nutritional requirements, subdivided into saturated,
monounsaturated, polyunsaturated and trans- varieties. In this terminology, the term “saturated”
means a fat molecule with no double bonds between the carbon atoms. The distinction is important
because when they are packed together, molecules with double bonds resist compacting. The long-
chain, omega-3 and omega-6 polyunsaturated fatty acids are called “essential” fatty acids because
they or their precursors cannot be made by human bodies and must be found in our diet.4 These fatty
acids are carbon chain compounds with several double bonds, subdivided into those whose first dou-
ble bond occurs on the third carbon from the methyl end (omega-3 essential fatty acids) and those
whose first double bond occurs on the sixth carbon from the methyl end (omega-6 essential fatty
acids).
6
9. From the beginning of human evolution up until about 1920, the human diet consisted of between a
1:1 and a 2:1 ratio of omega-6 to omega-3 essential fatty acids.5 The modern (American) diet has
shifted this balance to between 10:1 and 30:1, as omega-3 essential fatty acids have declined due to
(1) the prevalent use of omega-6 seed oils (especially corn) instead of omega-3-rich plants to feed the
animals that make up our animal protein, (2) decline of fish consumption and general lack of flaxseed
oil, canola oil, walnuts, and leafy green vegetables in our diet, (3) hydrogenization of oils for use in
processed foods, thus increasing trans-fatty acid intake which interferes with fatty acid synthesis (4)
loss of cereal germ by modern milling processes, and (5) increase in sugar intake which interferes with
the enzymes of fatty acid synthesis.6
Alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentanoic acid (EPA) are the missing
omega-3-rich essential fatty acids needed to restore this balance. ALA is an essential fatty acid, and
DHA and EPA are derivatives, sometimes referred to as “conditionally essential fatty acids”7 because
they are dietary essentials for some people, especially those with metabolic deficiencies. DHA (written
as 22:6n-3, meaning twenty-two carbon atoms, six double bonds, and the first double bond at the
third carbon) is the brain’s principal long chain omega-3 fatty acid. DHA also is found in high amounts
in the mitochondria of nerve cells. Of equal importance, EPA (written as 20:5n-3) is the active anti-
inflammatory omega-3 essential fatty acid. EPA can be synthesized by the body from ALA, and DHA
can be synthesized by the body from EPA. ALA has the formula 18:3n-3.
7
10. The clinical studies thus far have generally used fish oil (about 3:2 EPA to DHA), except for one study
that used a pharmaceutical grade of pure EPA.8 There is no clear evidence of the relative contribution
of EPA and DHA to the observed outcomes. Stoll asserts that EPA appears to be “the most mood stabi-
lizing component” in fish oil, and cites anecdotal data that suggest that too much DHA relative to EPA
may actually worsen mood.9 However, this statement requires scientific validation.
It has been suggested that depletion of omega-3 essential fatty acids impairs membrane function. The
brain uses its cell membranes to control the movement of electrically charged ions such as sodium and
potassium and organizing the activities of the brain at the cellular level. The “lipid bilayer” forms the
membrane around brain cells and is shaped by phospholipids, containing two fatty acids for each
phospholipid molecule. It is theorized by Stoll that a 1:1 ratio of omega-6 to omega-3 essential fatty
acids in the diet promotes an optimal balance of phospholipids in cell membranes. Stoll concludes that:
“lipid bilayers composed of proper amounts of omega-3 fatty acids appear to function best.”10 He the-
orizes that the greater fluidity of cell membranes rich in omega-3 essential fatty acids may account for
this conclusion.11 In addition, neurotransmitter receptors lie embedded in the matrix of all membranes,
and their 3-dimensional conformation is dependent on the essential fatty acids, which give structure to
the membranes through their multiple double bonds.
Additional data are accumulating that suggest an association between essential fatty acids and the
“mood” neurotransmitter, serotonin. Severely depressed patients have lower levels of serotonin
8
11. metabolites.12 Both cholesterol lowering therapies and low cholesterol levels have been associated with
an increased risk of suicide. The prevailing theory holds that low cholesterol levels lower serotonin uti-
lization.13 However, drug and diet therapies to lower cholesterol also alter essential fatty acid levels.
Cholesterol levels may be only a surrogate marker for changes in essential fatty acids.
Stoll concludes that: “the implications of omega-3 deficiency on the brain are profound and span the
entire human life cycle. Beginning in pregnancy, premature birth and its potential neurologic complica-
tions may result from omega-3 deficiency. Babies who are bottle-fed or born from omega-3 deficient
mothers will lack the omega-3 fatty acids necessary for optimal cognitive and visual development.
Children deprived of omega-3s may have less ability to pay attention and control impulsive behavior
and may be at higher risk for depression. Teenagers and adults with omega-3 deficiency may be more
prone to hostility or violence. In aging, the loss of omega-3 fatty acids in the brain may result in a
higher risk of stroke, memory problems, or dementia. Individuals of any age without adequate
amounts of omega-3 fatty acids in the brain and body may also be at higher risk for depression, bipo-
lar disorder, and possibly other psychiatric disorders.”14
depression
It has been theorized that omega-3 essential fatty acids may reduce the development of depression,
since depressive patients show significant depletion of omega-3s. There appears to be an inverse rela-
tionship between the prevalence of major depression and the amount of fish consumed per capita
9
12. worldwide.15 There are at least four studies showing reduced levels of omega-3 essential fatty acids in
the blood of depressed patients.16 Uncontrolled clinical trials of omega-3 essential fatty acid supple-
ments have shown promise in the treatment of major depression, and several controlled trials are
underway.17
postpartum depression
Depletion of maternal omega-3 essential fatty acids also has been noted during pregnancy. The physi-
ology of pregnancy involves the mobilization of essential fatty acids from maternal stores to the fetus
and especially the developing brain and nervous system. Supplementation with omega-3 essential fatty
acids may ensure adequate supplies for the needs of the mother and the developing fetus and should
be as common as folic acid supplementation--now an almost universal health precaution to prevent
birth defects (e.g. Spina bifida).
Without dietary supplementation, levels of omega-3 essential fatty acids may remain low for some
time postpartum, particularly in lactating women since considerable amounts of omega-3s are found in
breast milk. Thus, it is possible that maternal omega-3 essential fatty acids depletion may contribute to
postpartum depression. Joseph Hibbeln of the National Institute of Alcohol Abuse and Alcoholism of
the National Institute of Health conducted an elegant 1998 epidemiological study showing an inverse
relationship between fish consumption and major depression that suggests a causal relationship.18
Double-blind clinical studies are needed to confirm this suggestion.
10
13. breast milk and infant formula
Breast milk, unlike infant formula, has relatively high concentrations of omega-3 and omega-6 essential
fatty acids. The World Health Organization recommends that essential fatty acids be added to infant
formulas. European infant formulas are routinely fortified, and the FDA has only recently allowed the
addition of fatty acids to infant formulas sold in the United States. It goes without saying that lactating
mothers should also consider taking omega-3 essential fatty acid supplements as long as they are
breast-feeding. Omega-3 essential fatty acids are crucial in the development of the fetal and neonatal
brain and nervous system. One study showed that intellectual development may also suffer in infants
deprived of these fatty acids.19
bipolar disorder
Bipolar disorder (manic-depressive illness) is a common neuropsychiatric illness with a high morbidity
and mortality. Despite the use of mood-stabilizing drugs, including lithium and valproate, there are
high rates of recurrence. All of the currently available mood-stabilizing drugs appear to affect neuronal
signal transduction (or second messenger) mechanisms. Biochemical studies have shown that dietary
treatment with omega-3 essential fatty acids leads to the incorporation of these compounds into the
membranes crucial for cell signaling. This mechanism may be similar to some of the actions of lithium
and valproate.
11
14. A recent double-blind study by Andrew Stoll, M.D., et al. (1999) demonstrated that dietary supplemen-
tation with omega-3 essential fatty acids resulted in marked mood-stabilizing activity for persons with
bipolar disorder. Significant group differences in favor of fish oil were seen on the Hamilton Depression
Scale, the Global Assessment Scale and the Clinical Global Impression. The authors concluded that
omega-3 essential fatty acids were well tolerated and improved the short-term course of the illness.20
schizophrenia
There is increasing evidence that neuronal injury due to oxidative stress (excess oxygen radicals) con-
tributes to the pathophysiology of schizophrenia. Considerable effort has been directed towards deter-
mining the respective roles of increased oxidative stress (resulting in increased fatty acid breakdown)
versus dietary deficiencies or defective metabolic pathways on membrane fatty acid concentration.21 It
is likely that both processes are important for the development of a pathological state.
In an uncontrolled study, dietary supplementation with concentrated fish oil led to significant improve-
ment in negative (alogia, flat affect, anhedonia, apathy, motor retardation) but not positive symptoms
(hallucinations, disorganized thought) as rated by the Positive and Negative Syndrome Scale.
Improvement in clinical symptoms was related to increased levels of omega-3 essential fatty acids in the
blood.22 Thus, it is conceivable that dietary supplementation with antioxidants and omega-3 essential
fatty acids at the initial stages of illness may prevent further oxidative injury and thereby ameliorate and
prevent further possible deterioration of associated neurological and behavioral deficits in schizophrenia.
12
15. adverse effects and interactions
No adverse effects of omega-3 essential fatty acid supplementation are known, other than “fishy”
reflux or loose stools with higher doses. Persons taking an anti-clotting agent such as warfarin or high
doses of aspirin should be monitored for safety while taking omega-3 supplements, since the supple-
ments reduce platelet aggregation and could increase bleeding time. Theoretically, there could be a
mechanical interaction with lipid lowering drugs that could be “binding” with dietary fats. If these
medications are used, they should not be taken at the same time as the supplements. No one should
taper off or discontinue any medications without the advice of a physician.
dosage
Stoll recommends careful choice of omega-3 essential fatty acid supplements, avoiding fish liver oil
(which may contain excessive environmental pollutants) and emphasizing a high EPA-to-DHA ratio.
However, as stated above, fish oil (about 3:2 EPA to DHA) is the only scientifically validated product at
this point. Stoll recommends one to two grams of total omega-3 essential fatty acids (EPA plus DHA)
for health, mood or cognitive enhancement and clinical doses of from two to five grams per day (up to
9.6 grams per day was used in the bipolar disorder study described above).23

16. SAM-e (s-adenosylmethionine)
S-adenosylmethionine is approved for use as a prescription drug in Germany, Italy, Spain and Russia,
and has been in use in Europe for over three decades for relief from symptoms of depression. Unlike
long-chain omega-3 essential fatty acids, SAM-e is a substance normally produced by the human body.
Thus, it is not an essential nutrient, and does not have to be ingested. Its precursors are readily avail-
able. However, it does play a role in regulating the activity of norepinephrine, dopamine and serotonin,
the neurotransmitters implicated in major depression.24
Spurred by European acceptance, recent studies have shown promising, though not conclusive, evi-
dence of effectiveness of SAM-e in treating depression. Specifically, a comprehensive 1994 meta-analy-
sis published in Acta Scandinavica Neurologica assembled data from twenty-five double-blind studies
(fourteen against other antidepressants and eleven against placebo) to show the efficacy of SAM-e.25 It
found that the anti-depressant response rate ranged from seventeen to thirty-eight percent better for
SAM-e than for the placebos, and that the effect was comparable to that of other antidepressants.
Since SAM-e is poorly absorbed from the stomach, most of the studies have used large doses (200-400
mg/day by intravenous injection or 800-1600 mg/day orally), well beyond the dosages commonly taken
14
17. without a prescription. SAM-e has an important role in the structure of the lipid bilayer in cell mem-
branes, perhaps altering their electrical properties.26 This in turn appears to affect mood.
adverse effects and interactions
Mild and transient anxiety, insomnia, loose bowels and heartburn are the only noted physical effects.
However, SAM-e can induce mania in patients with bipolar disorder.27 Thus, bipolar disorder needs to
be ruled out before initiating use of SAM-e. A careful psychiatric evaluation is the appropriate way to
make this differential diagnosis.
dosage
Since the clinical trials employed very high doses, dosage is the major remaining controversy concern-
ing use of SAM-e in treating depression. The expense may also be an issue since the cost is not reim-
bursed. Advice of a physician is essential in the current state of medical knowledge, as there remain
serious questions about dosage and negative side effect potential for SAM-e.
conclusion
In conclusion, use of omega-3 fatty acids and SAM-e for depression and for some other symptoms of
mental disorder is supported by a basic neurobiological rationale and by some clinical evidence. The
evidence thus far looks very promising. However, for SAM-e, dosage needs to be monitored, and coun-
15
18. seling to avoid triggering a manic episode is
very important. Use of alternative treatments
should be discussed between a person desiring
to use them and any professional providing
treatment, as part of an effective treatment
regimen. Professionals need to recognize that
consumers have ready access to alternative
treatments and that failure to discuss them
may lead to failures in the treatment process.
Candid discussion of these and other evidence-
based alternative treatments should become a
routine aspect of contemporary treatment of
mental disorders.
19. Acknowledgments
The state mental health planning and advisory councils have joined together to form the National
Association of Mental Health Planning and Advisory Councils (NAMHPAC). Federal law requires the
establishment of mental health planning councils to review state applications for block grant funding,
to serve as advocates for adults with serious mental disorders and children with serious emotional dis-
turbance, and to monitor and evaluate state mental health planning systems. Although these activities
are mandated, many states do not provide funding to support them. In many cases, this lack of fund-
ing, combined with council members’ often short tenures, prevent these organizations from making
their full impact on service delivery and consumer and family empowerment. NAMHPAC provides tech-
nical assistance to these organizations in the areas of exemplary practices, organizational development,
and information sharing. In addition, NAMHPAC provides a national presence on mental health policy
issues on behalf of the state planning and advisory councils.
