Recent Longevity News for the seven days ending
11/18/09. You should consult your doctor if you are taking any
medications.
I got behind because the video card on my computer went
bad. I had to wait a day for a new one from Dell. By that time there
was nearly a thousand articles/abstracts in my RSS feed to go through in
addition to sites such as Doctor's Guide.
Flibanserin Drug: Will 'Female Viagra' Boost Sex Drive? - Time Magazine,
11/18/09 - "Whether or not the FDA approves flibanserin
to treat women's libidos, the German company's trial results have reignited a
decade-long debate over the merit of the HSDD diagnosis — the most commonly
diagnosed female sexual dysfunction"
Depression as deadly as smoking, study finds - Science Daily, 11/18/09 -

Vitamin
B niacin offers no extra benefit to statin therapy in seniors already diagnosed
with coronary artery disease, study suggests - Science Daily, 11/18/09 -
"This does not mean that niacin therapy may not have
other cardiovascular benefits, but any such benefits are independent of reducing
the amount of plaque buildup and patients should be aware of that ... Lima
cautions that an ongoing national study of the long-term vascular benefits of
dual therapy and whether extended-release niacin,
also known as nicotinic acid, lowers death rates from heart disease should
provide more definitive data" - Note: The article implies that
prescription Niaspan works better than immediate release niacin. See
http://www.lipidsonline.org/slides/slide01.cfm?q=effect+of+niacin&dpg=7
which implies the opposite. The prescription might have less flush but I
couldn't tell the difference. Like I've said in the past, the flush gets
less the longer you use it and is practically non-existent after you taken it
for several months if you take it with food. Also, the slow release may
produce liver damages. See:
Antifibrotic effects of green tea - Science Daily, 11/18/09 -
"The researchers drew a conclusion that
green tea may protect liver cells and reduce
the deposition of collagen fibers in the liver. Green tea provides a safe and
effective strategy for improving hepatic
fibrosis" - See

Scientists find molecular trigger that helps prevent aging and disease -
Science Daily, 11/18/09 - "diabetes reduces activation
of CBP, leading Dr. Mobbs to conclude that a high-calorie diet that leads to
diabetes would have the opposite effect of dietary
restriction and would accelerate aging"
Alcohol May Reduce Men's Heart Risk - WebMD, 11/18/09 -
"Drinking any type of
alcohol lowered the risk of serious
heart disease in men, with the amount of risk reduction associated with the
amount of alcohol: ... Light drinking reduced risk by 35% ... Moderate drinking
reduced risk by 51% ... High and very high levels of drinking reduced risk by
54% and 50% ... Light drinking was up to 5 grams a day -- or about one glass of
wine, one and one-half beers, or less than a half glass of hard liquor ...
Moderate drinking was 5 to 30 grams a day, or about two glasses of wine, two or
three beers, or a half to one glass of hard liquor ... High and very high levels
of drinking were 30 to 90 grams a day, or about five or more glasses of wine,
seven or more beers, and one to one and a half glasses or more of hard liquor"
How fish
is cooked affects heart-health benefits of omega-3 fatty acids - Science
Daily, 11/17/09 - "If you eat fish to gain the
heart-health benefits of its omega-3 fatty acids,
baked or boiled fish is better than fried, salted or dried"
HDL Cholesterol Inversely Associated With Cancer Risk - Doctor's Guide,
11/16/09 - "The investigators found a significant
inverse relationship between baseline HDL-C levels
and the rate of incident cancer, reporting that
every 10 mg/dL increase in HDL-C was associated with a 24% (95% CI: 1%-41%)
relative reduction in the cancer rate ... They also found a significant inverse
relationship between baseline LDL-C and the rate of incident cancer, with every
10-mg/dL reduction in LDL-C associated with a 14% (95% CI: 9%-18%) relative
increase in the cancer rate ... There was a significant direct relationship
between both age and BMI and rate of incident cancer, with every 5-year increase
in age associated with a 28% (95% CI: 16%-42%) relative increase in cancer (P <
.001) and every 1-kg/m2 increase in BMI associated with an 18% (95% CI: 6%-31%)
relative increase in the cancer rate"
Previous
seasonal flu infections may provide some level of H1N1 immunity - Science
Daily, 11/16/09 - "What we have found is that the swine
flu has similarities to the seasonal flu, which
appear to provide some level of pre-existing immunity. This suggests that it
could make the disease less severe in the general population than originally
feared ... "We found that the immune system's T cells can recognize a
significant percent of the markers in swine flu." T cells are infection-fighting
white blood cells in the body's immune system. "Nobody knows what level of
immunity is sufficient for protection. We do know that a T cell response is not
enough to prevent being infected by the virus. But, if infected, our data
suggests that T cells in those who have previously been exposed to influenza may
make the infection less severe," ... In a normal flu season, influenza infects
as much as 20 percent of the U.S. population, causes more than 200,000
hospitalizations and kills about 36,000 people" - Exactly what I've been
saying in previous newsletters.
Inadequate levels of vitamin D may significantly increase risk of stroke, heart
disease and death - Science Daily, 11/16/09 - "a new
study by researchers at the Heart Institute at Intermountain Medical Center in
Salt Lake City suggests that Vitamin D
contributes to a strong and healthy heart as well -- and that inadequate levels
of the vitamin may significantly increase a person's risk of
stroke,
heart disease, and death, even among people who've never had heart disease
... patients with very low levels of Vitamin D were 77 percent more likely to
die, 45 percent more likely to develop coronary artery disease, and 78 percent
were more likely to have a stroke than patients with normal levels. Patients
with very low levels of Vitamin D were also twice as likely to develop heart
failure than those with normal Vitamin D levels ... Recently, studies have also
linked Vitamin D to the regulation of many other bodily functions including
blood pressure, glucose control, and inflammation, all of which are important
risk factors related to heart disease" - See
vitamin D at Amazon.com.
Niacin Tops Zetia in Cutting Artery Plaque - WebMD, 11/16/09 -
"The question is whether
ezetimibe works at all
... Niacin has been around for 50 years. It's a
well-understood drug, and in this trial it was clearly superior ... Ultrasound
images of neck arteries showed that Niaspan reduced artery plaque by about 2%.
Zetia did not slow plaque buildup, although it did lower cholesterol" -
See
niacin at Amazon.com.
ARBITER 6-HALTS: HDL Raising With Niacin Superior to Ezetimibe - Medscape,
11/16/09 - "Adding extended-release
niacin (Niaspan, Abbott) to statin therapy
results in a significant regression of atherosclerosis as measured by carotid
intima-media thickness (IMT), whereas the addition of
ezetimibe (Zetia,
Merck/Schering-Plough) to statin therapy did not, according to an eagerly
anticipated study" - See
niacin at Amazon.com.
Heart
and bone damage from low vitamin D tied to declines in sex hormones -
Science Daily, 11/15/09 - "Researchers at Johns Hopkins
are reporting what is believed to be the first conclusive evidence in men that
the long-term ill effects of vitamin D deficiency are amplified by lower levels
of the key sex hormone estrogen, but not testosterone ... an adequate daily
intake of vitamin D is between 200 and 400
international units, but Michos feels this is inadequate to achieve optimal
nutrient blood levels (above 30 nanograms per milliliter). Previous results from
the same nationwide survey showed that 41 percent of men and 53 percent of women
are technically deficient in the nutrient, with vitamin D levels below 28
nanograms per milliliter" - See
vitamin D at Amazon.com.
HbA1c Levels Predict Carotid IMT in Diabetic Adolescents - Medscape,
11/13/09 -
"For every 1% increase in HbA1c,
the likelihood of having a thicker common
carotid IMT increased by 35%, after adjustment for sex, systolic blood
pressure z-score, and insulin use ... These data suggest that poor glycemic
control is associated with structural changes in the carotid artery that are
consistent with early atherosclerosis"
Egg
Yolks May Reduce Risk of Age-Related Macular Degeneration - Medscape,
11/13/09 - "Two eggs per day is probably all that is
needed to maximize blood levels of lutein and
zeaxanthin as well as macular pigment optic
density (MPOD) status"
NSAIDs
Prevent Early Sign Of Alzheimer Disease In Mice Science Daily, 11/12/09 -
"If taking nonsteroidal antiinflammatory drugs (NSAIDs)
such as ibuprofen or naproxen is to protect you from developing
Alzheimer disease then you will have to start
taking them at a very early age according to research in a mouse model of the
disease"
Another
Cause of Obesity: The Bacteria in Your Gut? - Time Magazine, 11/12/09 -
"When one group of mice was fed a typical Western diet,
high in fat and sugars, they tended to gain weight and grow more Firmicutes gut
bacteria and fewer Bacteroidetes. In mice given a low-fat, plant-based chow, the
distribution of the two groups of bugs flipped and the animals remained lean.
It's not clear whether the balance of gut bugs causes weight gain or is a result
of it, but the findings suggest that a "gut profile" could potentially serve as
a diagnostic tool for identifying who might have a propensity for obesity. If,
for instance, your gut environment contains a preponderance of Firmicutes, then
your body may be predisposed to digest calories in a way that leads to greater
fat storage. In fact, in Gordon's earlier work with identical twins of different
weights, he found that the obese twin tended to have more Firmicutes colonies
than the leaner sibling ...factors like gut microbes, which scientists
traditionally would not think of exerting influence on genes, may have a
surprisingly powerful effect, changing how a body's genes would normally control
the way it digest food and breaks it down into energy"

Gut microflora and obesity: Study highlights potential for pre-, probiotics
- Nutra USA, 11/12/09 - "One approach could involve
searching for nutritional interventions to modify specific gut microbial
species. Dietary components (prebiotics) might be found that alter growth of
specific microbial species capable of affecting host physiology, and the
Turnbaugh model can be used to pinpoint these elements and decipher the
mechanisms of the host-microbe collaboration"
Study: High Bisphenol A ( BPA) Linked to Sex Problems in Men - Science
Daily, 11/11/09 - "Compared to the unexposed factory
workers in the study, BPA-exposed workers were
four times more likely to report erectile
dysfunction, low sexual desire, and less than optimal satisfaction with
their sex lives. They were seven times more likely to report problems with
ejaculation ... BPA has been used for more than three decades to make plastic
bottles and other products shatter resistant and clear. It is also used in the
lining of many canned foods and a wide range of other commercial goods"
Unexpected Consequences Of Proton Pump Inhibitor Use In Reflux Disease -
Science Daily, 11/11/09 - "there are many unexpected
consequences and side effects from this class of
drugs. They can include: increased rates of hip fractures, possibly related
to altered calcium absorption; possible but yet unproven altered vitamin B12 and
iron absorption, related to alteration of the gastric pH; increased odds of
acquiring nosocomial Clostridium difficile-associated diarrhea; and increased
odds of contracting community-acquired pneumonia"
High
Fructose Corn Syrup: A Recipe For Hypertension, Study Finds - Science Daily,
11/10/09 - "people who ate or drank more than 74 grams
per day of fructose (2.5 sugary soft drinks per
day) increased their risk of developing
hypertension. Specifically, a diet of more than 74 grams per day of fructose
led to a 28%, 36%, and 87% higher risk for blood pressure levels of 135/85,
140/90, and 160/100 mmHg, respectively. (A normal blood pressure reading is
below 120/80 mmHg.)"
Heating,
Air-Conditioning And Carpets May Be Hazardous To Your Health - Science
Daily, 11/10/09 - "A damp building with high humidity
may lead to increased levels of dust mites
and mold, leading to increased
allergic respiratory symptoms, as well as the
worsening of asthma. And even if someone is not
allergic, molds may produce mycotoxins and volatile organic chemicals (VOCs)
that smell bad and may cause respiratory irritation"

Extended-Release Niacin or Ezetimibe and Carotid Intima-Media Thickness - N
Engl J Med. 2009 Nov 15 - "This
comparative-effectiveness trial shows that the use of extended-release
niacin causes a significant regression of
carotid intima-media thickness when
combined with a statin and that niacin is superior to ezetimibe"
Higher
circulating levels of igf-1 are associated with longer leukocyte telomere length
in healthy subjects - Mech Ageing Dev. 2009 Nov 10 -
"Both IGF-1 and LTL diminished with age
(IGF-1, r=-0.601, P<0.001; LTL, r=-0.706, P<0.001). Age-adjusted LTL was
positively associated with IGF-1 level throughout the age range of the cohort
(r=0.270, P<0.001). IGF-1 accounted for about 10% of the inter-individual
variation in LTL over and above the effect of age. Our findings suggest that
both circulating IGF-1 and LTL are indices of healthy aging in humans" -
Note: hGH increases igf-1.
The effect
of chronic antipsychotic drug administration on nitric oxide synthase activity
and gene expression in rat penile tissues - Eur Neuropsychopharmacol. 2009
Nov 13 - "Antipsychotic
drug treatment may be associated with common and problematic
sexual dysfunction, especially impotence,
which can diminish quality of life and lead to treatment noncompliance.
Nitric oxide synthase (NOS) is an important
cellular modulator of erectile function. We have therefore investigated the
effect of antipsychotic drug on activity and gene expression of NOS in rat
penile tissues. The activity of constitutive NOS was significantly suppressed
below control by a 21days administration of 1mg/kg haloperidol, which also
significantly decreased expression of endothelial NOS (eNOS) and neural NOS
mRNA. Risperidone at 0.5mg/kg also reduced eNOS mRNA expression. Haloperidol or
risperidone did not change gene expression and activity of inducible NOS (iNOS).
Quetiapine significantly increased activity and mRNA expression of iNOS with 20
and 40mg/kg doses"
Metformin
associated with lower cancer mortality in type 2 diabetes (ZODIAC-16) -
Diabetes Care. 2009 Nov 16 - "Median follow-up time was
9.6 years, average age at baseline was 68 years, and average HbA1c was 7.5%.
Five hundred seventy patients died, of which 122 from malignancies. SMR for
cancer mortality was 1.47 (95%CI 1.22-1.76). In
patients taking metformin compared to patients
not taking metformin at baseline, the adjusted hazard ratio (HR) for cancer
mortality was 0.43 (95%CI 0.23-0.80), and the HR with every increase of 1 gram
of metformin was 0.58 (95%CI 0.36-0.93) ... In general, patients with type 2
diabetes are at increased risk for cancer
mortality. In our group, metformin use was associated with lower cancer
mortality when compared to non-metformin use. Although the design cannot be
conclusive about causality, our results suggest a protective effect of metformin
on cancer mortality"
Aspirin is
associated with reduced cardiovascular and all-cause mortality in type 2
diabetes in a primary prevention setting: The Fremantle Diabetes Study -
Diabetes Care. 2009 Nov 16 - "Regular low-dose
aspirin may reduce all-cause and CVD
mortality in a primary prevention setting in
type 2 diabetes. All-cause mortality reductions appear greatest in men and those
aged >/=65 years. The present observational data support recommendations that
aspirin should be used in primary CVD prevention in all but the lowest risk
patients"
Neat Tech Stuff :
- Two easy ways to speed up Windows Vista:
- Go “Start – Control Panel”. In the “Classic” menu select “System”.
On the left select “Advanced system settings”. This should bring up the
“System Properties” box. Select the “Advanced” tab. Under performance
select “Settings…”. Select “Adjust for best performance” then “Apply”
then “OK”. Vista will go back to the classic menu and you’ll lose a lot
of the tacky whistles and bells like the rubbery icons at the bottom but
the performance will be much better.
- “Go “Start – Run” or “Start – Search” if you don’t have “Run” (there
a way to get “Run” back. Type “msconfig” and enter. This will bring up
the “System Configuration” box. Under the “General” tab select
“Selective startup” and under that select “Load system services” and
“Load startup items”. Select the “Startup” tab. Uncheck everything you
don’t need loaded into the memory on startup (they will still work) like
iTunes, Acrobat, Quick Time, Real Player, etc. Select “Apply” and “OK”.
The next time you boot the computer you’ll get a dialog box saying that
you did that. Just select “Don’t show this again”.

UniBlue.com bundle, it makes it easy to clean up registries and
check and update drivers.

concerns over whether this is a healthy diet for preventing heart disease,
stroke, and cancer. There is also potential loss of bone, and the potential
for people with liver and kidney problems to have trouble with the high
amounts of protein in these diets ... Those on the Atkins diet lost
significantly more weight over the first six months of the study. After 12

resulted in only a 12 percent reduction ... people on a diet including 35
percent of calories from MUFAs as well as those on a traditional low-fat,
high carbohydrate diet lost an average of 11 pounds over six months.
However, by 18 months, three times as many people on the MUFA diet remained
with the program and kept off the lost weight while the others regained an
average of five pounds each"

Vegetarian diet on solid ground, experts say - USA Today, 12/7/01 -
"McDougall points to a recent study in the Archives
of Internal Medicine that looked at Seventh-Day Adventists in California, a
group made up mostly of vegetarians. The 12-year of study of 34,192 people
found that on average, group members lived 10 years longer than the general
population ... Vegetarians have a 40% less risk of cancer and much less risk
of heart disease, diabetes, hypertension, kidney disease and other problems
that are common among meat eaters"

Diet Shows Small Cholesterol Benefit, But Don't Opt for Bacon Over Broccoli
Just Yet - WebMD, 3/23/01 -
"there could be a small benefit to a high-fat diet.
They randomly assigned 45 adults to eat for 3 months either a high-fat
low-carbohydrate diet or a more conventional "heart healthy" diet (American
Heart Association Step 2 diet). They found that the while the AHA diet was
more effective at reducing overall levels of LDL, only the high-fat diet
caused a significant reduction in the amount of very small, dense LDL
particles, a form of the bad cholesterol that is thought to be particularly
harmful to arteries that nourish the heart, and a major contributor to
atherosclerosis, or hardening of the arteries ... vegetarians had much
healthier arteries than the other group ... the real answer may be that a
Mediterranean style diet, rich in fruits, vegetables, and grains and
relatively low in animals fats, may be the easiest to follow, because it's
not as Spartan as the Ornish regimen or as monotonous as the Atkins
approach"
