Mitigating Potential Bias
Since I have received and honorarium
from Ferring
MFI Pharma
and am talking about Probiotics and
mentioning their products today there is
the potential for bias
I will mitigate this bias because I will be
discussing generic brands and other brands as
well as the sponsored brands
I will be following ministry guidelines
pertaining to this topic
I will remind the audience that I received an
honorarium from this company years ago when I
mention their products
Why physicians have
comphlementary

FISH OILS
eating fish or by taking supplements.
Fish rich in the beneficial oils known as omega-3 fatty acids
include mackerel, tuna, salmon, sturgeon, mullet, bluefish,
anchovy, sardines, herring, trout
1 gram of omega-3 fatty acids in about 3.5 ounces of fish.
.
Essential Fats (1)
Two types of fat are essential: omega 3
and omega 6 fatty acids
Docosahexaenoic acid (DHA) and
Eicosopentanoic Acid (EPA) are both
long chain omega-3 fatty acids that are
major structural fats of the brain
Dopamine and serotonin receptors are
composed mainly of omega 3 fatty acids
Essential Fats (2)
An omega 6 fatty acid, arachidonic acid
(ARA) is equally important for brain
development (babies)
Found in meat, eggs and milk
Generally, diets contain too much omega
6 fat. Need to increase omega 3s
OMEGA 3 AND
HYPERTRIGLICERIDEMIA
Ten studies show long-chain omega-3 fatty acids to be
effective in the treatment of hypertriglyceridemia.
The average decrease in triglycerides was 29%, total
cholesterol 11.6%, very low density lipoprotein (VLDL)
30.2%, and low-density lipoprotein (LDL) 32.5%.
One study found LDLs to increase by 25%.
many of the RCTs had serious shortcomings the authors
do not recommended routine use of omega-3’s for
hypertriglyceridemia
Lewis A, Lookinland S, Beckstrand RL, Tiedeman ME Treatment of
hypertriglyceridemia with omega-3 fatty acids: a systematic review.J Am
Acad Nurse Pract. 2004 Sep;16(9):384-95.
FISH OILS AND HEART
DISEASE
Yzebe and Lievre did a meta-analysis of 10 RCTs with
14,727 patients that showed that daily intake of omega-3
fatty acids for a mean duration of 37 months decreased all
causes of mortality by 16% and the incidence of death due
to MI by 24%.
because of the suboptimal quality of the studies included
into the meta-analysis and the absence of data in patients
receiving statins, the authors suggest that these results do
not justify adding fish oils systematically to the heavy
pharmaceutical assortment already recommended in CHD
patients
Yzebe D, Lievre M, Fish oils in the care of coronary heart
disease patients: a meta-analysis of randomized controlled
trials. Fundam Clin Pharmacol. 2004 Oct;18(5):581-92.
FISH OILS AND HEART
A Cochrane review-48 RCT’s and 41 cohort analyses
“it is not clear that dietary or supplemental omega 3 fats alter
total mortality, combined cardiovascular events or cancers in
people with, or at high risk of, cardiovascular disease or in the
general population.’
no evidence we should advise people to stop taking rich
sources of omega 3 fats, but further high quality trials are
needed to confirm suggestions of a protective effect of omega
3 fats on cardiovascular health.
no clear evidence that omega 3 fats differ in effectiveness
according to fish or plant sources, dietary or supplemental
sources, dose

Ness AR, Capps NE, Davey Smith G, Riemersma RA, Ebrahim SB. Omega 3 fatty acids for prevention
and treatment of cardiovascular disease.Cochrane Database Syst Rev. 2004 Oct 18;(4):CD003177.
FISH OILS AND HIGH BP
8 studies in hypertensive participants found a statistically significant
reduction in systolic and diastolic BP; 2.56 mmHg (95% CI 0.58 to
4.53) and 1.47 mmHg (95% CI 0.41 to 2.53), respectively.
Meta-regression showed no significant relationship between dose
of fish oil and the effect on BP.
Conclusion: The small but statistically significant effects of fish-oil
supplements in hypertensive participants in this review have
important implications for population health and lowering the risk of
stroke and ischaemic heart disease. Their modest effects, however,
mean that they should not be recommended as an alternative to
BP-lowering drugs where guidelines recommend treatment.

EPA AND DEPRESSION
60 outpatients major depressive disorder score
>/=15 in the 17-item Hamilton Depression Rating
Scale (HDRS) were randomly allocated to
receive daily either 1000 mg EPA or 20 mg
fluoxetine, or their combination for 8 weeks.
EPA and fluoxetine had equal therapeutic effects
in major depressive disorder. EPA + fluoxetine
combination was superior to either of them alone.

eicosapentaenoic acid and fluoxetine, separately and in
combination, in major depressive disorder Aust N Z J
Psychiatry. 2008 Mar;42(3):192-8.
FISH OILS AND DEPRESSION
Several epidemiological studies suggest covariation
between seafood consumption and rates of mood
disorders.
Biological marker studies indicate deficits in omega-3 fatty
acids in people with depressive disorders,
several treatment studies indicate therapeutic benefits from
omega-3 supplementation.

EPA-FFA REDUCES COLONIC POLYPS
55 patients with FAP
Treatment with EPA-FFA for 6 months was associated with a mean
22.4% (95% CI 5.1% to 39.6%) reduction in polyp number (p=0.012)
and a 29.8% (3.6% to 56.1%) decrease in the sum of polyp
diameters (p=0.027).
Global polyp burden worsened over 6 months in the placebo group
(-0.34) unlike the EPA-FFA group (+0.09, difference 0.42 (0.100.75), p=0.011).
EPA-FFA was well tolerated with an incidence of adverse events
similar to placebo.

FISH OILS AND INFANTS
infant formulas containing DHA provide improved performance on the
Mental Development Index in term infants and better mental
development in pre-term infants.
One study demonstrated significantly better visual maturation of
term infants fed long-chain fatty acids including DHA compared to
control formula for a 12-month period.
A metanalysis of 5 RCT’s involving term infants and three RCT’s
involving pre-term infants found that in term infants, ALA (alpha
linoleic) supplementation was associated with increased weight and
length at 12 months, which was at least 4 months after the end of
dietary intervention.
FISH OIL CONCERNS
high doses of fish oil is POSSIBLY UNSAFE. Taking more than 3 grams
per day might keep blood from clotting and can increase the chance of
bleeding
High doses of fish oil might also reduce the immune system’s activity,
reducing the body’s ability to fight infection
larger amounts can increase levels of the “bad” LDL cholesterol in some
people? Do blood tests periodically to ensure LDL cholesterols is not
elevated
Some fish meats (especially shark, king mackerel, and farm-raised
salmon) can be contaminated with mercury and other industrial and
environmental chemicals,
fish oil supplements typically do not contain these contaminants.
FISH OIL CONCERNS
An implanted defibrillator (a surgically placed
device to prevent irregular heartbeat):
Some, but not all, research suggests that fish
oil might increase the risk of irregular heartbeat
in patients with an implanted defibrillator.
Stay on the safe side by avoiding fish oil
supplements if patient has a defibrillator

prehypertensive subgroups
BP was not significantly reduced in the normotensive subgroups
9 trials used chocolate containing 50% to 70% cocoa compared with white
chocolate or other cocoa-free controls,
6 trials compared high- with low-flavanol cocoa products.

GLUCOSAMINE
Glucosamine is an
aminomonosaccharide, which is a
normal constituent of
glycosaminoglycans in cartilage
matrix and synovial fluid.
POSSIBLE MECHANISM
OF ACTION
experiments on cultured human chondrocytes
have shown that glucosamine increases the
production of aggrecans, and reduces the
formation of nitric oxide and interleukin in
response to interleukin 1ß
Therefore it may have a chondroprotective and
anti-inflammatory effect.
experiments in animals have suggested that
circulating glucosamine can localize in cartilage.

advise our patients with osteoarthritis of the knee to take
glucosamine. Rheumatology 2004; 43: 100-101
METANALYSIS-OA OF
KNEE AND HIP
McAlinden et al reviewed 15 randomly
assigned double blind controlled trials of
more than 4 weeks duration for
osteoarthritis of the knee and hip and
found glucosamine had a positive effect
on symptoms. The researchers had
some concerns about the methological
flaws of many of the studies.[i]

Antibiotic Associated Diarrhea
Antibiotics have helped save millions of lives,
but like most drugs, there are side effects.
The most common side effect is diarrhea (AAD), and it
is reported that 20% of people taking antibiotics are
affected by AAD.
Diarrhea results when the balance between “good” and
“bad” bacteria is disrupted.

Antibiotic Associated Diarrhea
In some cases, the result of “bad” bacterial
over-proliferation is just a mild case of diarrhea.
In other cases, pathogenic bacteria may produce toxins
which can build up and damage the bowel wall, leading
to inflammation.

GINGER
Zingiber officinale (ginger) has
been used as medicine by Folk,
Chinese and Indian herbalists for
centuries.
NAUSEA AND VOMITING
There have been a number of
randomly assigned, double blind
controlled trials for nausea and
vomiting

SURGERY
In two studies involving elective laparoscopic and major
gynecological surgery the incidence of nausea and
vomiting were statistically better than placebo and the
request for postoperative antiemetics was lower in those
receiving ginger.

303 subjects reporting nausea were enrolled (26.3% of 1151)
received a gauze pad saturated with a randomly chosen aromatherapy
agent and were told to inhale deeply 3 times

The powdered rhizome of ginger
reduced the symptoms of motion
sickness better than
dimenhydrinate and placebo in
patients that were experimentally
provoked by a revolving chair.

SIDE EFFECTS
Few side effects are linked to
ginger when it is taken in small
doses.
Side effects most often reported
are gas, bloating, heartburn, and
nausea. These effects are most
often associated with powdered
ginger.
MASSAGE THERAPY
Pre-term infants who were given 15 minute
massage 3 times a day for 10 days while still
in the incubator gained 47% more weight than
control and performed better on infant
development scores
Similar results were found in cocaine
exposed babies, HIV exposed babies and in
full term infants
When parents were taught to massage their
infants it seemed that parents had less
anxiety and reduced stress.

MASSAGE THERAPY
Pregnant woman who were massaged versus
receiving relaxation therapy reported lowered
anxiety and depression, less pain and fewer
obstetrical and postnatal complications.
When significant others were taught to
massage their pregnant partners during
childbirth, the massaged women had lower
anxiety, and depression, less need for
medication, less postpartum depression and
fewer days in hospital compared to women
who received standard breathing coaching

lavender (Lavendula vera) oil, or rest
periods
Those who received the massage
with lavender oil reported a greater
improvement in mood as measured
by a self-rating 4-point scale.

MASSAGE
RCT 72 hospitalized children and adolescents
half with adjustment disorder and half with
depression

significantly declined during the 5-day treatment
(P=.01), and the massage group was less
depressed than the control group at the end

MANIPULATION
2870 non-randomized LBP patients with acute or
chronic back pain attending primary care physicians or
chiropractics.
In the short term patients with chronic back pain
treated by chiropractors reported less pain and both
acute and chronic chiropractic patients experience
somewhat greater relief up to one year.

MANIPULATION
672 patients randomized to receive medical or
chiropractic care of low back pain
expressed greater satisfaction from chiropractic
care even though there was no significant
difference in pain improvement or disability
scores.
They found that receipt of self-care advice and
explanation of treatment accounted for the
difference in patient satisfaction.
