Higher Levels of Adiponectin Associated With Lower Risk of Type 2 Diabetes -
Doctor's Guide, 7/7/09 - "Although these epidemiologic
studies cannot establish causality, the consistency of the association across
diverse populations, the dose-response relationship, and the supportive findings
in mechanistic studies indicate that adiponectin
is a promising target for the reduction of risk of type 2
diabetes"
Muscle Damage From Statins May Evade Blood Test - WebMD, 7/6/09 -
"Studies suggest that between 10% and 15% of patients
who take cholesterol-lowering statin drugs like
Crestor, Lipitor, Lescol, Mevacor, Zocor, and Pravachol experience muscle pain
as a side effect of treatment ... Most do not end up with muscle damage, and a
simple blood test is routinely performed to identify patients who do ... But the
new study suggests the test for elevated levels of an enzyme associated with
muscle injury, known as creatine phosphokinase or CPK, may be less accurate than
widely believed ... Our findings call into question whether normal or mildly
elevated levels of serum (CPK) can be used to exclude underlying and possibly
ongoing muscle injury"

Understanding The Anticancer Effects Of Vitamin D3 - Science Daily, 7/6/09 -
"the active form of vitamin
D3 directly activates the CST5 gene in human colon
cancer cell lines, increasing levels of cystatin D protein. Functionally,
cystatin D was shown to inhibit the growth of human colon cancer cells lines in
vitro and when they were xenotransplanted into mice. As knocking down expression
of cystatin D in human colon cancer cell lines rendered them unresponsive to the
antiproliferative effects of the active form of vitamin D3, the authors conclude
that CST5 is a candidate tumor suppressor gene and that it mediates a large
proportion of the anticancer effects of the
active form of vitamin D3" - See
vitamin D at Amazon.com.
Muscle
Damage May Be Present In Some Patients Taking Statins - Science Daily,
7/6/09 - "Although in clinical practice, the majority of
patients with muscle symptoms improve rapidly after cessation of therapy, our
findings support that a subgroup of patients appears to be more susceptible to
statin-associated myotoxicity, suffering
persistent structural injury"
Folate linked to lower colorectal cancer risk: Study - Nutra USA, 7/6/09 -
"A possible explanation for the contradictory results of
studies with the vitamin and colorectal cancer may
be the difference between the synthetic and natural forms of the vitamin. “The
fact that folic acid, which is not a naturally
occurring form of the vitamin, is used by food and pharmaceutical industries for
fortification and supplementation is potentially of importance,” wrote Tufts
University’s Mason in Nutrition Reviews ... On passage through the intestinal
wall, folic acid is converted to 5-methyltetrahydrofolate, the naturally
circulating form of folate. However, some studies have suggested that oral doses
of folic acid in high doses may overwhelm this conversion pathway, leading to
measurable levels of folic acid in the blood ... There has been some concern
that this oxidized, non-substituted form of folate might feasibly be detrimental
because it is not a naturally occurring co-enzymatic form of the vitamin"

Fish Oil and
Heart Health - J Cardiovasc Pharmacol. 2009 Jun 26 -
"Large controlled trials have shown that intake of
fish oil (marine n-3 fatty acids,
eicosapentaenoic acid, and docosahexaenoic acid), whether from dietary
sources or fish oil supplements, may exhibit beneficial effects on total and
cardiovascular disease mortality.
Stabilization of cell membranes and suppression of cardiac arrhythmias have been
identified as possible mechanisms. Moreover, n-3 fatty acids have
anti-inflammatory effects, reduce blood pressure, and may also be
antiatherogenic. Finally, high doses of n-3 fatty acids can lower elevated serum
triglyceride levels. The n-3 index (erythrocyte eicosapentaenoic acid plus
docosahexaenoic acid) may be considered as a potential risk marker for coronary
heart disease mortality, especially sudden cardiac death. The balance of n-6 to
n-3 fatty acids is an important determinant in decreasing the risk for coronary
heart disease, both in the primary and in the secondary prevention of coronary
heart disease. Patients with known coronary heart disease should be recommended
to consume n-3 fatty acid supplements at 1 g per day, without raising concerns
for interactions with other medications or side effects. On the other hand, fish
in the diet (preferably oily fish, 1-2 meals/week) should be considered as part
of a healthy diet low in saturated fat"
Fatty fish
and fish omega-3 fatty acid intakes decrease the breast cancer risk: a
case-control study - BMC Cancer. 2009 Jun 30;9(1):216 -
"Using a multivariate logistic regression model, high
intake of fatty fish was associated with a reduced risk for
breast cancer in both pre- and postmenopausal
women (OR [95% CI] for highest vs. lowest intake quartiles, p for trend: 0.19
[0.08 to 0.45], p < 0.001 for premenopausal women, 0.27 [0.11 to 0.66], p =
0.005 for postmenopausal women). Similarly, reductions in breast cancer risk
were observed among postmenopausal subjects who consumed more than 0.101 g of
EPA (OR [95% CI]: 0.38 [0.15 to 0.96]) and
0.213 g of DHA (OR [95% CI]: 0.32 [0.13 to 0.82])
from fish per day compared to the reference group who consumed less than 0.014 g
of EPA and 0.037 g of DHA per day. Among premenopausal women, there was a
significant reduction in breast cancer risk for the highest intake quartiles of
omega-3 fatty acids (ORs [95% CI]: 0.46 [0.22 to 0.96]), compared to the
reference group who consumed the lowest quartile of intake" - See

Effect of
adjunct metformin treatment on levels of plasma lipids in patients with type 1
diabetes - Diabetes Obes Metab. 2009 Jun 25 - "After
1 year, in those patients who did not start or stop statin therapy during the
trial, metformin treatment significantly
reduced total and LDL cholesterol by approximately 0.3 mmol/l compared with
placebo (p = 0.021 and p = 0.018 respectively). Adjustment for statin use or
known cardiovascular disease did not change conclusions. In statin users
(metformin: n = 22, placebo: n = 13), metformin significantly lowered levels of
LDL and non-HDL cholesterol by approximately 0.5 mmol/l compared with placebo"
New users of
metformin are at low risk of incident cancer: A cohort study among people with
type 2 diabetes - Diabetes Care. 2009 Jun 29 -
"Activation of AMPK can suppress tumour formation and inhibit cell growth, in
addition to lowering blood glucose levels. We tested the hypothesis that
metformin reduces the risk of
cancer in people with type 2 diabetes ... Cancer
was diagnosed among 7.3% of 4,085 metformin users compared with 11.6% of 4,085
comparators, with median times to cancer of 3.5 years and 2.6 years respectively
(p < 0.001). The unadjusted hazard ratio for cancer was 0.46 (0.40-0.53). After
adjusting for sex, age, BMI, HbA1c, deprivation, smoking and other drug use,
there was still a significantly reduced risk of cancer associated with
metformin: 0.63 (0.53-0.75)" - See

"Compounds with neuromodulatory properties have been
effective in only a limited number of cases of
hypothalamic-pituitary-dependent Cushing disease, the most common form of
Cushing syndrome. These agents include serotonin antagonists
(cyproheptadine, ketanserin, ritanserin), dopamine agonists (bromocriptine,
cabergoline), GABA agonists (valproic acid [sodium valproate]), and
somatostatin analogs (octreotide). Interesting new avenues at the pituitary
level involve the potential use of thiazolidinedione compounds, such as
rosiglitazone, and of retinoic acid, which are ligands of different nuclear
hormone receptors involved in hypothalamic-pituitary regulation"

Wilson's
Reverse T3 Dominance Syndrome - knoxintegrativemed.com -
"However, when a person experiences prolonged
stress, the adrenal glands respond by manufacturing a large amount of
cortisol. Cortisol inhibits the conversion of T4 to T3 and favors the
conversion of T4 to RT3. If stress is prolonged, a condition called Reverse
T3 Dominance occurs and persists even after the stress passes and cortisol
levels fall. Apparently, RT3 itself acts like cortisol and blocks the
conversion of T4 to T3"
-
Wilson's Syndrome - providentmedical.com -
"We know that elevated amounts of cortisol, the
major stress hormone, can block 5 prime deiodinase, keeping T4 from being
converted to T3. This results in most of the T4 being converted into
reverse T3, which then needs the available 5 prime deiodinase to be
converted into T2."

Disappointing Data Confound Claims For DHEA Effectiveness [against
Alzheimer's] - Psychiatric News, 6/6/03 -
"DHEA has been reported

hormone," which in response to stress is released in large quantities that
have been linked to neuronal stress and damage" - Does anyone detect
bias in that title? I don't know if DHEA helps Alzheimer's or not but I
feel the title should have been something like "Alzheimer's Shows Trend
Toward Improvement with DHEA at 3 Months". Their attitude seems to be that
nothing works except what we write prescriptions for. The way I understand
it, Alzheimer's usually gets worse, not better and
cholinesterase inhibitors slow the
disease, they don't reverse it and three months is a short time to determine
if it is working. For example, see the following in the same issue of

"What they found was that a single enzyme in fat
cells that raises levels of cortisol — the “fight or flight” stress hormone
— triggers fat accumulation around the belly and its associated ill effects
... The researchers were drawn to the role of cortisol because patients with
a rare illness known as Cushing syndrome — who have too much of the steroid
hormone in their blood — develop severe obesity concentrated around their
middles and become diabetic ... Since overweight people without Cushing
syndrome typically don’t have too much cortisol in their bloodstreams, Flier
hypothesized that they may be producing high cortisol levels solely in their
fat cells — possibly because the enzyme HSD-1, which makes cortisol from an
inactive molecule, is overactive ... The level of cortisol in their stomach
fat tissue was 15 percent to 30 percent higher than in their non-engineered
counterparts"
- Note: The way I read this article, the final culprit is still the cortisol
and there are ways to reduce cortisol now.

RU-486 could aid variety of ills - MSNBC, 11/2/00 - "RU-486's ability to
block the action of a different hormone � cortisol � has prompted doctors to
try it for psychotic depression. In addition to feeling sad and worthless,
people with this devastating condition have distorted thinking and often
suffer delusions or hallucinations. Many
become suicidal.
They have very, very disturbing and crazy thoughts ... and they have no
ability to suppress them,� said Joseph K. Belanoff, a California
psychiatrist who is chief executive officer of Corcept Therapeutics Inc., a
small pharmaceutical company. Corcept is sponsoring a study of RU-486 for
psychotic depression.
Several lines of evidence have led researchers to suspect that some of the
symptoms of psychotic depression are caused by an excess of cortisol in the
brain. Cortisol levels rise in response to stress and may be abnormally
elevated in depressed individuals. Similar symptoms can occur in patients
with Cushing's syndrome, an overabundance of cortisol usually caused by a
tumor, and RU-486 has cured the mental disturbance in some
such cases.
Our feeling has been that a lot of the cognitive problems and delusions that
you see in some of the patients are due to the [cortisol],� said Alan F.
Schatzberg, chairman of the psychiatry department at Stanford University
School of Medicine, where researchers are conducting a study that will test
RU-486 on 30 patients with psychotic depression.
RU-486 or other cortisol-blocking drugs �may be better alternatives than ...
some of the typical treatments� such as antipsychotic drugs or electric
shock therapy, he said."

Neuroscience finds foggy link between depression and memory loss - CNN,
4/18/00 -
"Studies show that prolonged depression or stress
leads to elevated levels of cortisol, a "stress" hormone produced by the
adrenal glands. This in turn appears to shrink or atrophy the hippocampus,
the sea-horse shaped part of the brain associated with many kinds of memory
and learning."

has been used clinically for more than 40 years, primarily as the local
injectable anesthetic Novocaine. Despite the widespread use of procaine,
reports of side effects have been rare, and are usually associated with
excessive dosage, rapid absorption or inadvertent intravascular injection
... For the pharmacokinetics study, participants will receive Anticort(TM)
at a single oral dose of 200 mg (cohort A), 400 mg (cohort B), 600 mg
(cohort C) or 800 mg (cohort D). For the 8-week continuous dosing study,
participants will receive 200 mg (1 pill per day; cohort A), 400 mg (1 pill
twice daily; cohort B), 600 mg (1 pill three times daily; cohort C) or 800
mg (2 pills twice daily; cohort D). To ensure the safety of each dose level,
these cohorts will be enrolled sequentially"

Gerovital GH-3 information - International Antiaging Systems -
"It is also known that Gerovital-H3 can help reduce
cortisol levels, the hormone responsible for stress and a rare hormone in
that it is one of the few that increases with age. It is believed that
high-cortisol levels lead to accelerated aging because cortisol “attacks”
the hypothalamus, the area of the brain that “controls” the endocrine
system. Ironically cortisol may run out-of-control due to its ability to
damage the hypothalamus that controls the adrenal glands that produce
cortisol!" - Note: I'm not a doctor but the way I understand it,
GH-3 (procaine HCl) reduces 3-hydroxy-3-methylglutaryl-coenzyme A reductase
(HMG-CoA) activity. This is what statins do to lower cholesterol. Cortisol
is made from cholesterol therefore less cholesterol equals less cortisol.
The company making Anticort (procaine HCl), stopped after phase II studies.

- drlowe.com -
"During stress (such as surgery or an auto

Wilson's Reverse T3 Dominance Syndrome - knoxintegrativemed.com -
"However, when a person experiences prolonged
stress, the adrenal glands respond by manufacturing a large amount of
cortisol. Cortisol inhibits the conversion of T4 to T3 and favors the
conversion of T4 to RT3. If stress is prolonged, a condition called Reverse
T3 Dominance occurs and persists even after the stress passes and cortisol
levels fall. Apparently, RT3 itself acts like cortisol and blocks the
conversion of T4 to T3"

- "Under stress, the body excretes
corticotrophin-releasing hormone and adrenalin. This reaction stimulates the

glucocorticoid, stimulates glucose release into the bloodstream, which,
during periods of chronic stress, creates an excessive release of insulin.
Insulin, which is part of the endocrine system, is a fat-storage hormone
that overrides the stress signal from adrenalin to burn fat. The excess
release of insulin gives the body the message to store fat in the abdomen"

Mirtazapine Attenuates Hypothalamic-pituitary-adrenocortical Axis
Hyperactivity in Depressed Patients - Doctor's Guide, 4/17/03 -
"it has been shown to have an acute inhibiting effect on cortisol secretion
in healthy subjects ... Apparently,
mirtazapine
rapidly attenuates HPA axis hyperactivity in
depressed patients via direct
pharmaco-endocrinological effects. However, this amelioration of HPA system
dysregulation is not necessarily related to clinical improvement" -

New Stress-Buster Drugs Block Hormone Binding - Clinical Psychiatry
News, 4/03 - "A new class of anxiety-relieving
drugs—agents that interrupt core hypothalamic-pituitary-adrenal (HPA) stress
signals—will emerge in the next 2-3 years ... In his HPA axis model of
depression, the affected individual has a blunted ability to counterregulate
in response to stress-induced cortisol increases, and thus is unable to turn
off the fight-or-flight HPA mechanism. The result is constant anxiety and
overreaction to external stimuli, followed by a sense of learned
helplessness and loss of motivation. Many symptoms of deeply entrenched
depression—anxiety,
loss of appetite, reduced libido, elevated heart rate,
hypertension, and dyslipidemia—point to HPA dysregulation ... People
with melancholic depression do tend to produce abnormally high levels of
CRH. These individuals also have elevated levels of cortisol"

- How Your Mind Can
Heal Your Body - Time Magazine, 1/20/03 -
"More and more doctors—and patients—recognize that
mental states and physical well-being are intimately connected. An unhealthy
body can lead to an unhealthy mind, and an illness of the mind can trigger
or worsen diseases in the body. Fixing a problem in one place, moreover, can
often help the other ... Somehow depression
makes the body less responsive to insulin, the hormone that processes blood
sugar—plausibly through the action of cortisol,
a hormone that can interfere with insulin sensitivity and that is often
elevated in depressed patients ... Cortisol may also make depressed patients
more prone to osteoporosis ... Cizza estimates that some 350,000 women get
osteoporosis each year because of depression. Cortisol appears to interfere
with the ability of the bones to absorb calcium and offset the natural
calcium loss that comes with menopause and aging"

Depression-Altered Immune Function/Steroid Regulation Unrelated to Elevated
Cortisol - Doctor's Guide, 12/19/02
- New Vistas in
Antidepressant Development - Medscape, 11/21/02 -
"The evidence for corticotropin-releasing factor (CRF) hypersecretion in
depression and certain anxiety disorders is compelling ... CRF is
transported to the anterior pituitary via the hypothalamo-hypophyseal portal
system where it promotes the release of adrenocorticotropic hormone (ACTH)
into the general circulation, which in turn stimulates the production and
release of cortisol from the adrenal cortex ... Numerous studies have
revealed that the direct injection of CRF into the CNS of laboratory animals
produces effects reminiscent of the cardinal symptoms of depression,
including decreased libido"

pressure and high blood sugar, along with depression, fatigue, irritability
and weakened bones ... a protein called PPAR-gamma, which is found on
pituitary gland tumor cells, appears to be linked to overproduction of ACTH
... researchers injected mice with ACTH-secreting pituitary tumor cells and
then treated them with commonly used diabetes drugs,
rosiglitazone (Avandia) and troglitazone, or an inactive placebo ...
There was an 85% reduction in ACTH and a corresponding 96% reduction in

Cushing's syndrome is caused by prolonged
exposure of the body's tissues to high levels of the hormone cortisol. I've
talked to doctors who implied that it was black and white, i.e. you have
Cushing's or you don't. My personal opinion, and I'm not a doctor, is that
there is a linear gray area in between.
